TSO

In January 2011, in connection with our acquisition of the assets of Asphelia Pharmaceuticals, Inc. (“Asphelia”), we acquired the exclusive rights to TSO in North America, South America and Japan under a sublicense agreement with OvaMed GmbH (“OvaMed”), as well as a manufacturing and supply agreement with OvaMed to provide us with our clinical and commercial requirements for TSO. In December 2011, we entered into a binding Terms of Agreement with OvaMed and Dr. Falk Pharma GmbH (“Falk”), OvaMed’s sublicensee in Europe for gastroenterology indications, under which we agreed to collaborate in the development of TSO for Crohn’s and, in March 2012, entered into the Collaboration Agreement with OvaMed and Falk.

TSO is the microscopic eggs of a parasitic helminth, or worm, that is found in pigs. TSO is not a human pathogen and is eliminated from the body within several weeks without treatment. Multiple investigator-sponsored clinical trials of TSO for the treatment of Crohn’s and UC have been completed in which TSO demonstrated clinical benefit with regard to accepted outcome measurements of remission of disease and was shown to be well tolerated. An Investigational New Drug Application (“IND”) was filed with the United States Food and Drug Administration (“FDA”) in September 2011 and we initiated a single dose, dose escalation study in patients with Crohn’s that was completed in February 2012. The study showed that TSO is safe and well tolerated. Falk is currently conducting a Phase 2 clinical trial in Europe evaluating TSO in Crohn’s. An independent data safety monitoring committee will conduct an interim analysis of clinical data early in the second quarter of 2012 and communicate their findings to Falk in the form of a blinded recommendation regarding the trial. Based on current enrollment rates, preliminary results from Falk’s Phase 2 clinical trial in Crohn’s are currently expected in the first quarter of 2013. We expect to initiate a multi-center Phase 2 clinical trial in Crohn’s in the United States in the second quarter of 2012. Assuming positive results from these Phase 2 clinical trials, we expect to collaborate with Falk for future Phase 3 clinical trials in Crohn’s to support a submission by us of a Biologic License Application (“BLA”) with the FDA.

CNDO–109

In November 2007, we acquired exclusive worldwide rights to develop and market CNDO–109 from the University College London Business PLC (“UCLB”). CNDO–109 is a compound that has been shown to activate NK cells. When activated, NK cells have the ability to differentiate between normal cells and cancer cells, and kill cancer cells by granzyme mediated lysis, a biochemical process whereby the NK cells directly kill cancer cells by destroying their cell membranes and structures.

In vitro preclinical studies conducted at the University College of London have demonstrated that CNDO–109 activated NK cells directly kill cells that cause hematologic malignancies including myeloid leukemia and multiple myeloma, as well as breast, prostate and ovarian cancers. Results from the first investigator-sponsored Phase 1 clinical trial of CNDO–109 activated NK cells in eight patients with high-risk AML were presented at the American Society of Hematology (ASH) Annual Meeting on December 13, 2011. Although the primary endpoint of the Phase 1 clinical trial was safety, based on the data obtained from this Phase 1 study, we believe early efficacy was observed. The investigators observed that the majority of the patients experienced a longer complete remission than their previous complete remission,

In February 2012, we submitted an IND for a multi-center Phase 1/2 clinical trial to evaluate CNDO–109 activated NK cells in patients with relapsed AML. In March 2012, the FDA indicated to us they had no further comments on our IND. We intend to commence this trial in mid-2012 and to use the results of this Phase 1/2 clinical trial to develop a plan for future clinical trials of CNDO–109 to support the filing of a BLA in the United States and similar marketing applications in other countries.

Immunology Therapeutics Markets

Autoimmune diseases represent a diverse collection of diseases in terms of their demographic profile and primary clinical manifestations. The phenotypic commonality between them, however, is the damage to tissues and organs that arise from the loss of tolerance or recognition of “self.” Autoimmune disorders include inflammatory bowel

disease (“IBD”) such as Crohn’s and UC, MS, rheumatoid arthritis, lupus, and type-1 diabetes. According to a 2010 Decision Resources report, in the United States and Japan, the prevalence of Crohn’s was 585,000 patients, UC was 712,000 patients and MS was 400,000 patients. Prevalence rates for all autoimmune disorders are expected to continue to rise in the next several years. Each of these diseases is believed to be associated with an excessive inflammatory response by the T helper (Th) cells and suppressed activity of T regulatory (Treg) cells.

Crohn’s is characterized by inflammation of the gastrointestinal tract that causes painful and debilitating symptoms. Most patients with Crohn’s experience relapses, and no current therapy is completely effective in preventing acute flares. Although immunosuppressants and TNF-inhibitors are effective maintenance therapies, according to an article published in Alimentary Pharmacology & Therapeutics in 2011, fewer than 50% of patients maintain long-term remission with these drugs. According to a 2007 article in Surgical Clinics of North America, the majority of Crohn’s patients require surgery during their lifetime despite available therapies. Therefore, the greatest unmet need is for more effective maintenance therapies that are also safe for long-term use.

The etiology and pathophysiology of UC are not fully understood, but research appearing in several industry publications, including Inflammatory Bowel Disease (2006) and the World Journal of Gastroenterology (2006), strongly suggests that genetic susceptibility and environmental factors, coupled with an abnormal immune response, contribute to the development of the disease. Despite significant advances in the understanding of genetic susceptibility and its role in IBD, novel, targeted therapies for the treatment of UC have yet to be identified. The need for more effective maintenance therapies with sustained long-term efficacy are the greatest unmet need in the management of UC.

MS is an autoimmune inflammatory disease of the central nervous system that is characterized by progressive neuronal loss that manifests clinically as worsening physical disability. The key pathophysiological hallmark of MS is the loss of myelin, a layer of lipids and proteins produced by cells called oligodendrocytes that wrap around the neuron and act like an insulating sheath to facilitate electrical conduction along the nerve. Destruction of myelin by an inflammatory cascade leads to neuronal degeneration. As a result, we believe that there is a substantial unmet need for effective treatments for chronic progressive MS as well as a need for therapies that are more conveniently delivered (e.g., oral agents, less frequently administered injectable drugs).

Since many autoimmune diseases are being diagnosed in younger patients, the impact of long-term medical treatment, including dosing convenience and safety, is becoming increasingly important.

Oncology Therapeutics Markets

The American Cancer Society estimates that over 1.6 million people in the United States are expected to be diagnosed with cancer in 2012, excluding basal and squamous cell skin cancers and in situ carcinomas (other than urinary bladder carcinomas). This is an increase of approximately 33% from the estimated number of new cancer diagnoses in 2000. We believe this rate is unlikely to decrease in the foreseeable future as the causes of cancer are multiple and poorly understood.

Despite continuous advances every year in the field of cancer research, there remains a significant unmet medical need in the treatment of cancer, as the overall five-year survival rate for a cancer patient diagnosed between 2001 and 2007 still averages only 67% according to the American Cancer Society. According to that same source, cancer is the second leading cause of mortality in the United States behind heart disease. Overall, the American Cancer Society estimates that approximately one in four deaths in the United States is due to cancer.

AML is one of the most deadly and most common types of acute leukemia in adults. There are over 30,000 cases worldwide, primarily afflicting elderly and relapsed and refractory populations. Once diagnosed with AML, patients typically receive induction and consolidation chemotherapy, with the majority achieving complete remission. However, about 70–80% of patients who achieve first complete remission will relapse, and the overall five year survival rate is less than 25%.

One of the main treatments for cancer is chemotherapy. While chemotherapy is the most widely used class of anti-cancer agents, individual chemotherapeutic agents show limited efficacy because tumors maintain complex machinery to repair the DNA damage to tumor cells caused by chemotherapy. Solutions to this problem include combination chemotherapy, but while combination chemotherapy has been intensively studied, it offers only limited hope for improvement as a result of additive toxicities. The limitations inherent in chemotherapy are mirrored by limitations in other therapeutic modalities for cancer, including radiation therapy, targeted therapies and surgical intervention. Each of these therapies either has high levels of toxicity and/or potentially severe adverse events, which in turn frequently limit the amount of treatment that can be administered to a patient.

As a result, we believe that there is a significant unmet medical need for alternatives to existing chemotherapy drugs that do not have the associated toxicities of traditional chemotherapy drugs.

Our Product Candidates

TSO

TSO is a biologic product candidate for the treatment of autoimmune diseases. We initially plan to investigate TSO for the treatment of Crohn’s, UC and MS. TSO originates from the work of Dr. Joel V. Weinstock, currently the Chief of the Division of Gastroenterology/Hepatology at Tufts New England Medical Center in Boston. Dr. Weinstock’s research has centered on the evolutionary role of parasitic helminth (worm) infections in the prevention of inflammatory diseases such as IBD, specifically Crohn’s and UC. Dr. Weinstock has discovered that when the microscopic eggs of a certain helminth, preferably T. suis, the pig whipworm, are administered to patients with IBD a beneficial immune response is induced, which provides clinical benefit to the underlying disease with minimal side-effects. Dr. Weinstock is a consultant to us, a member of our scientific advisory board and certain of his colleagues are currently our consultants.

Background

The use of helminths in the treatment of autoimmune disease is based on the belief that the immune systems of populations living in the relatively sterile environments found in developed countries with little or no exposure to parasites may develop in abnormal ways. This “hygiene hypothesis” is based on epidemiologic findings of an inverse relationship between autoimmune diseases and helminthic colonization. According to articles published in The New England Journal of Medicine in 2002 and Inflammatory Bowel Disease in 2009, the incidence of IBD is highest in the developed world and in temperate climates, with positive correlations noted among persons of higher socioeconomic status and high levels of domestic hygiene experienced in childhood. Conversely, the incidence of IBD is rare in less developed countries and in persons with blue-collar jobs involving exposure to dirt and physical exercise.

In contrast to the epidemiologic findings of IBD, according to articles by Dr. Weinstock and others published in The New England Journal of Medicine in 2002 and the International Journal for Parasitology in 2007, the prevalence of helminths is highest in warm climates and in populations characterized by crowding, poor sanitation, and impure food supply. Furthermore, the incidence of IBD has increased over the past several decades, while the prevalence of helminths in the United States and Europe has steadily declined during the same time period. These findings have led to the hypothesis that eliminating intestinal helminths in the industrialized world has eliminated a natural T regulatory cell mechanism that prevents excessive T-cell activation such as occurs in IBD as well as in other immune-mediated diseases such as MS and allergies.

The immunologic basis for helminth therapy for IBD is derived from experimental animal and human data demonstrating that these organisms alter immune responses beyond those directed against the worms. In animal models, helminths blunt Th1 responses and promote Th2 responses associated with increased production of IL-4 and IL-3. Helminthic colonization in humans can result in diminished Th1 immune responses to challenges with unrelated antigens, as well as increased production of immunomodulatory molecules such as IL-10, transforming growth factor (TGF)-ß, and regulatory T-cells. Thus, as noted in the National Review of Immunology in 2007, genetically susceptible persons who are never exposed to helminths may lack a strong Th2 immune response and develop a poorly regulated and destructive intestinal Th1 response, leading to chronic colitis or ileitis.

TSO was chosen as an appropriate helminth for therapeutic application due to its ability to colonize in humans briefly without invading or infecting the host. Although not a human parasite, T. suis resembles the human whipworm T. Trichuris and is able to colonize a human host for several weeks before being eliminated from the body without any specific therapy. As reported in the American Journal of Gastroenterology in 2005, TSO has potential for being a natural immune system modulator without significant risk of causing disease in humans. Mature T. suis produce ova that exit the porcine host with the stool, however, ova are not infective until incubating in the soil for several weeks, thereby preventing direct host-to-host transmission. No human diseases have been associated with exposure to T. suis or TSO.

Third Party Clinical Trials

The initial safety and efficacy of TSO in Crohn’s has been evaluated in two open-label investigator-sponsored clinical trials. The first, a small pilot clinical trial conducted by Dr. Weinstock and his colleagues and reported in the American Journal of Gastroenterology in 2003, administered a single dose of 2500 embryonated TSO orally to four patients with refractory Crohn’s. Patients were followed every two weeks for at least 12 weeks, with the efficacy of therapy determined by the Crohn’s Disease Activity Index (“CDAI”) and the Inflammatory Bowel Disease Quality of Life questionnaire (“IBDQ”). Using an IBDQ score > 170 to indicate remission, three of four (75%) patients achieved remission by week 8. Similarly, three of four (75%) patients achieved remission during the observation period as assessed by a CDAI < 150. However, two of the three patients who achieved remission relapsed at the end of the 12-week observation period. No significant clinical complications or adverse events occurred in any of the patients in this study.

In a subsequent open-label clinical trial reported in GUT in 2005, Dr. Weinstock and his colleagues examined the safety and efficacy of TSO in 29 patients with active Crohn’s, defined by a CDAI > 220. Patients received TSO in individual aliquots of 2500 ova suspended in a solution every three weeks for 24 weeks. Patients maintained diaries of clinical symptoms, and disease activity was measured by CDAI. Therapy with TSO was associated with substantial and sustained improvement, with 79.3% patients experiencing a response (decrease in CDAI > 100 points or CDAI < 150) and 72.4% achieving remission (CDAI < 150) at week 24. TSO was well tolerated. No significant clinical complications or adverse events occurred in any of the patients in this study.

Falk is currently conducting a Phase 2 double-blind, randomized, placebo-controlled, multi-center trial in Europe evaluating the efficacy and safety of three different dosages of TSO in Crohn’s. This trial is expected to enroll over 200 patients. An independent data safety monitoring committee will conduct an interim analysis of clinical data early in the second quarter of 2012 and communicate their findings to in the form of a blinded recommendation regarding the trial. Based on current enrollment rates, preliminary results from Falk’s Phase 2 clinical trial in Crohn’s are currently expected in the first quarter of 2013.

Two investigator-sponsored studies of TSO have been conducted in patients with UC. The first study was a pilot study conducted by Dr. Weinstock and his colleagues (American Journal of Gastroenterology, 2003) in which three patients with refractory UC were treated with a single dose of 2500 embryonated T. suis eggs orally and observed every two weeks for 12 weeks. The IBDQ and Simple Clinical Colitis Activity Index (“SCCAI”) were used to determine the efficacy of therapy. Using an IBDQ score > 170 to define remission, all three patients had achieved remission by week eight. Using an SCCAI < 4 to indicate remission, each of the UC patients achieved remission during the treatment and observation period, and one patient experienced a relapse. No significant clinical complications or adverse events occurred in any of the patients in this study.

As reported in the American Journal of Gastroenterology in 2005, Dr. Weinstock and his colleagues subsequently conducted a randomized, double-blind, placebo-controlled clinical trial to determine the safety and efficacy of TSO in 54 patients with active UC (defined by an Ulcerative Colitis Disease Activity Index (“UCDAI”) > 4) who were treated with placebo or 2500 TSO every two weeks for 12 weeks. After the first 12 weeks of treatment, placebo-treated patients were switched to TSO for a second 12-week interval and TSO patients were switched to placebo. The blind was maintained during the crossover phase. In order to calculate UCDAI and SCCAI scores, patients kept diaries detailing their clinical symptoms. The primary measure of efficacy was clinical improvement at 12 weeks, defined as a decrease in UCDAI > 4. Clinical remission, defined as UCDAI < 2, was a secondary endpoint. Of the 54 patients enrolled in the study, 24 received placebo and 30 received TSO during the first 12 weeks of the study. The proportion of patients achieving a favorable response was significantly higher with TSO compared with placebo in both the intention-to-treat (“ITT”) (43.3% vs. 16.7%, p = 0.04) and per protocol (PP) (44.8% vs. 17.4%, p = 0.04) populations. Only patients with active disease (UCDAI > 4) were included in the analysis of the crossover phase of

the study. Among 31 patients (n=15 for placebo, n=16 for TSO) analyzed, the percentage of TSO -treated patients achieving response was higher than that for placebo-treated patients (56.3% vs. 13.3%, p = 0.02). When the two study periods were combined, TSO administration was associated with significantly higher responses in both the ITT and PP populations. No significant clinical complications or adverse events occurred in any of the treated patients in this study.

In a study reported in the Multiple Sclerosis Journal in 2011, Dr. John Fleming and his colleagues at the University of Wisconsin studied five subjects with newly diagnosed, treatment-naïve, relapsing–remitting multiple sclerosis (“RRMS”). They were given 2500 TSO orally every 2 weeks for 3 months in a baseline versus treatment controlled trial. They showed that the mean number of new gadolinium-enhancing magnetic resonance imaging (“MRI”) lesions (n-Gdþ) fell from 6.6 at baseline to 2.0 at the end of TSO administration, and two months after TSO was discontinued, the mean number of n-Gdþ rose to 5.8 new lesions. No significant adverse effects were observed. In preliminary immunological investigations, increases in the serum level of the cytokines IL-4 and IL-10 were noted in four of the five subjects. These first five patients represented the first part of a 2-part study (known as HINT-1 and HINT-2). Additional patients are currently being studied for up to 10 months. Results from this second cohort are expected in the first half of 2013.

In studies to be presented by Dr. John Fleming and by Dr. Per Soelberg Soerensen, Copenhagen Denmark, at the American Academy of Neurology in New Orleans on April 25, 2012, TSO was used in MS patients with strong safety data. Abstracts for these studies, entitled “Temporal Changes in MRI Activity, Inflammation, Immunomodulation, and Gene Expression in Relapsing-Remitting Multiple Sclerosis Subjects Treated with Helminth Probiotic Trichuris Suis” (Fleming) and “Trichuris Suis Ova Therapy for Relapsing Multiple Sclerosis—A Safety Study” (Soerenson) are available on the American Academy of Neurology 2012 Annual Meeting website.

We are also aware of additional ongoing or planned investigator-initiated clinical trials evaluating TSO in various indications, including MS, UC, and rheumatoid arthritis.

Our Clinical Trial Program

As the result of a pre-IND meeting held among representatives of our company, OvaMed and the FDA, the FDA indicated that no additional pre-clinical studies were required to open the IND in the United States, which was filed with the FDA in September 2011. In February 2012, we announced results from our Phase 1 single dose, dose escalation study in patients with Crohn’s.

The Phase 1 clinical trial was a multi-center, sequential dose-escalation, double-blind, placebo-controlled study, the primary objective of which was to evaluate the safety and tolerability of TSO. The trial enrolled 36 patients with Crohn’s ranging in age from 20 to 54 with an equal distribution of male and female patients in three single dose cohorts of orally administered 500, 2500 and 7500 ova. Each cohort had 12 patients, with nine patients receiving TSO and three receiving placebo. Primary safety assessments were determined at day 14 post dose.

Table of Contents

Overall, TSO was found to be safe and well tolerated across all three dose levels tested. There were only two adverse events (metallic taste and sour taste) that were considered to be study drug related as assessed by the investigators, one which was reported in the 7500 ova dose group and the other in a patient receiving placebo, respectively. All other reported events were assessed as unrelated to study drug and were self-limiting. Mild gastrointestinal side effects such as nausea (in one placebo treated patient and two TSO treated patients) and diarrhea and/or abdominal pain (in two TSO treated patients) were reported. Safety laboratory values were assessed throughout the study and no clinically significant adverse trends were observed and no laboratory-related adverse events were reported. There were no serious adverse events reported and no patient discontinued the study prematurely.

As a result of acceptable tolerance determined by this study, we expect to begin a multicenter Phase 2b study in patients with Crohn’s in the second quarter of 2012. Our future clinical trial program in Crohn’s will reflect the collaboration and cross-licenses between us and Falk under the Collaboration Agreement, enabling us to use in our regulatory filings data obtained from clinical trials in Crohn’s conducted by Falk in Europe. Based on current enrollment rates, preliminary results from the Falk Phase 2 trial are currently expected in the first quarter of 2013. A Steering Committee comprised of representatives of Falk, OvaMed and Coronado will oversee the Crohn’s development program, under which we and Falk are expected each to be responsible for clinical testing on approximately 50% of the total number of patients required for regulatory approval of TSO for Crohn’s in the United State and Europe.

We also plan to have discussions with the FDA regarding the requirements to initiate a Phase 2 trial in MS patients. In addition, we plan to conduct pilot studies and support certain investigator initiated clinical trials in various other autoimmune diseases.

Manufacturing

We have contracted with OvaMed to produce and supply us with all of our requirements of TSO. OvaMed’s contractor inoculates young pathogen-free pigs with T. suis from a master ova bank and harvests the ova which are incubated to maturity and are processed to remove any viruses and other pathogens. Ova then are processed and extensively tested to assure uniformity. They are then used to repopulate the master ova bank and are processed further by OvaMed into a final formulation of the drug product that is a clear, tasteless and odorless liquid. OvaMed manufacturing is conducted at one facility in Germany, which has received Good Manufacturing Practice, or GMP, certificate granted by the European Medicines Agency, or EMA. OvaMed’s manufacturing operations will be subject to an FDA inspection to assess compliance with FDA standards. See “Government Regulation and Product Approval.”

CNDO–109

CNDO–109 is a lysate (disrupted CTV-1 cells, cell membrane fragments, cell proteins and other cellular components) that activates donor NK cells. CTV-1 is a leukemic cell line recently re-classified as a T-cell acute lymphocytic leukemia (“ALL”). We acquired exclusive worldwide rights to develop and commercialize CNDO–109 activated NK cells for the treatment of cancer from UCLB.

Background

Standard therapy for patients with advanced cancer include chemotherapy therapies, or therapies that are toxic to the cells, that suppress the immune system and carry significant risks of life-threatening infections and other toxicities in the absence of hope for cure. Despite effective cancer therapies that induce clinical responses, including complete remissions, minimal residual disease (“MRD”), a term referring to disease that is undetectable by conventional morphologic methods, often remains and serves as a source of cancer recurrence. For years, scientists have studied ways to enhance the patient’s immune system to target cancer cells, maintain remission and possibly even eradicate all cancer cells in the body, including MRD. Researchers believe that a cure for cancer might be possible if immunotherapy is successfully applied to the treatment of cancer.

The most common immunotherapy studied to date involves the use of targeted humanized monoclonal antibodies such as rituximab (anti-CD20) or trastuzumab (anti-HER2/neu). These antibodies bind targets that are over-expressed on cancer cells and promote cell death by a number of immune mechanisms, including antibody dependent cell-mediated cytotoxicity (“ADCC”). In ADCC, the most common mechanism of tumor killing, the antibody tags the cancer cell and recruits the cells from the patient’s immune system to attack the tumor. Immune cells recruited by the antibody to kill the cancer include granulocytes, macrophages and NK cells.

Table of Contents

Another common therapy that activates the innate immune system involves the administration of high dose Interleukin-2 (“IL-2”). Through binding to the IL-2 receptor, IL-2 activates NK cells to attack cancer cells. After high-dose IL-2 therapy, NK cells are activated to search out and kill cancer cells. Unfortunately, the use of IL-2 therapy is limited because of its severe side effects, which include severe life-threatening infusion reactions and induction of autoimmune disease.

The importance of NK cells in the host system’s defense against cancer was recognized by Dr. Mark Lowdell at the Royal Free Hospital in London and others when they noted that patients who could mount an immune response to their AML became long-term survivors after chemotherapy. Researchers identified that a key to the successful immune response of the patient’s immune systems was the NK cell. Dr. Lowdell determined that activated NK cells were the key to eliminating AML cells and that NK cells require two signals to kill a tumor cell—a priming signal followed by a trigger signal. NK cells that can be activated by certain cancer cells provide both signals resulting in killing the cancer cell. Cancer cells that cannot be killed only trigger one signal and therefore are considered resistant to NK cells. NK cells which have not been primed cannot respond to the trigger. The “priming signal” can be provided by either cytokines, such as high dose IL-2 or IL-15 or by CNDO–109. In contrast to IL-2 or IL-15, NK cells activated by CNDO–109 retain their activated state after cryopreservation and thawing. This allows commercialization of the process since the NK cells can be activated with CNDO–109 and prepared at a manufacturing facility under GMP conditions and shipped to the clinical center as a frozen patient-specific dose, ready for infusion. The results of the research conducted by Dr. Lowdell and his colleagues were published in the British Journal of Haematology in 2002 and The Journal of Immunology in 2007 and all inventions and related intellectual property that arose from such research are covered by our license agreement with UCLB. Dr. Lowdell is a consultant to us.

Although AML is the prototype tumor lysed by CNDO–109 activated NK cells, CNDO–109 activated NK cells are expected to be active against most cancer types. Based on in vitro preclinical efficacy studies of CNDO–109 conducted by Dr. Lowdell at the Royal Free Hospital in London using human specimens of breast cancer, prostate and ovarian cancer, we expect CNDO–109 to be active against tumors that have been successfully treated by high dose IL-2 therapy such as renal cell carcinoma and melanoma.

The treatment of patients with CNDO–109 activated NK cells involves several steps. The activated NK cells are infused into the patient after resting NK cells are incubated with CNDO–109 for at least eight hours. Preparation of CNDO–109 activated NK cells takes about 24 hours from start to finish. If the source of the NK cells being used is someone other than the patient, “an allogeneic donor”, the patient will need some form of immunosuppression to allow the CNDO–109 activated NK cells to persist long enough to eradicate MRD. Preliminary data on a small number of patients from the UK Phase 1 clinical trial demonstrated that CNDO–109 activated NK cells can remain active for weeks. Due to the complex manufacturing requirements, we anticipate developing CNDO–109 activated NK cell therapy using PCT.

Completed Clinical Trial

An investigator-initiated Phase 1 clinical trial of CNDO–109 activated haploidentical NK cells was conducted at the Royal Free Hospital in London in eight patients with high risk (i.e. chemo-sensitive relapsed/refractory) AML who were not eligible for a stem cell transplant. The results of this trial were presented at the American Society of Hematology (ASH) Annual Meeting in December 2011. Although the primary endpoint of the Phase 1 clinical trial was safety, the results demonstrated that the majority of AML patients experienced a longer complete remission after receiving CNDO–109 activated NK cells than their previous complete remission.

Our Clinical Program

We submitted an IND for the CNDO–109 activated NK cell product in the United States in February 2012 using data from UCL’s Phase 1 clinical trial in the United Kingdom. We plan to initiate a Phase 1/2 clinical trial in the United States in mid-2012 using CNDO–109 to activate NK cells to treat MRD in AML patients with relapsed/refractory disease. In phase 1/2 oncology clinical trials, dose limiting toxicity (“DLT”) stopping rules are commonly applied. The CNDO–109 phase 1/2 trial is subject to a set of DLTs that could suspend or stop dose escalation by predetermined criteria, including allergic reactions, prolonged aplasia or other organ toxicities of a serious nature. We are also evaluating selected pilot Phase 1 clinical trials in other tumor types, including multiple myeloma breast, prostate and ovarian cancer, with both allogeneic and autologous cells.

Manufacturing

The manufacturing process for CNDO–109 activated NK cells is currently under development. We have produced a master cell bank and a working cell bank of CTV-1 cells in collaboration with BioReliance Corporation (“BioReliance”) in Maryland. Manufacture and testing of CNDO–109 activated NK cells for our planned Phase 1/2 clinical trial will be conducted at Progenitor^TM Cell Therapy, LLC (“PCT”), with facilities in Allendale, NJ and Mountain View, CA. We have entered into master service agreements with both companies as well as a supply agreement with PCT. The master service agreements provide the general framework for the relationships, with specific terms to be established in connection with particular projects. Indirectly, we also rely on Miltenyi Biotec to provide the equipment and reagents necessary for the identification and selection of NK cells.

Strategic Alliances and Commercial Agreements

TSO

Sublicense Agreement with OvaMed GmbH

In January 2011, in connection with our acquisition of the assets of Asphelia relating to TSO, Asphelia assigned the Exclusive Sublicense Agreement, dated December 2005, between Asphelia and OvaMed (as amended, the “OvaMed License”) and Manufacturing and Supply Agreement dated March 2006, between Asphelia and OvaMed (as amended, the “OvaMed Supply Agreement”) to us and we assumed Asphelia’s obligations under these agreements. Under the OvaMed License, we received an exclusive sublicense, with a right to grant additional sublicenses to third parties, under OvaMed’s patent rights and know-how to make, use and sell products encompassing TSO in North America, South America and Japan (the “Territory”). OvaMed’s patent rights arise, in turn, from an exclusive license granted in 2005 by the University of Iowa Research Foundation (“UIRF”) to OvaMed covering inventions and related intellectual property rights that arose as a result of research relating to TSO performed by Dr. Weinstock and his colleagues while employed by the University of Iowa. In November 2011, we entered into an agreement with UIRF and OvaMed primarily amending certain diligence provisions of the UIRF license agreement with OvaMed and obtaining certain rights in the event of an OvaMed breach of this license.

Under the OvaMed License, we are required to make milestone payments to OvaMed totaling up to approximately $5.45 million, primarily upon the achievement of various regulatory milestones for the first product that incorporates TSO, and additional milestone payments upon the achievement of regulatory milestones relating to subsequent indications. In the event that TSO is commercialized, we are obligated to pay to OvaMed royalties equal to 4% of net sales. Additionally, we are obligated to pay to OvaMed a percentage of certain consideration we receive from sublicensees (ranging from 10% to 20% of such consideration depending on the stage of clinical development at the time of the sublicense), as well as an annual license maintenance fee of $250,000 and reimbursement of patent costs. We are responsible for all clinical development and regulatory activities and costs relating to licensed products in the Territory. The OvaMed License terminates upon the expiration of the last licensed patent right, provided that either party may also terminate the agreement under certain customary conditions of breach and we have the right to terminate the OvaMed License with 30 days prior notice.

Under the OvaMed Supply Agreement, OvaMed agreed to manufacture and supply us with and we are required to purchase from OvaMed our clinical and commercial requirements of TSO at pre-determined prices. The OvaMed Supply Agreement currently expires in March 2013 but will automatically renew for successive one-year periods, unless we give 12 months’ prior notice of our election not to renew. The OvaMed Supply Agreement is subject to early termination by either party under certain customary conditions of breach and by us in the event of specified failures to supply or regulatory or safety failures.

In January 2011, as part of the purchase price for the Asphelia assets, we paid OvaMed an aggregate of approximately $3.4 million in satisfaction of Asphelia’s agreement to pay OvaMed for certain development costs, the annual license maintenance fee and patent reimbursement costs. We agreed that, subject to certain conditions, the IND would initially be submitted by OvaMed and subsequently transferred to us and such transfer was effected in March 2012.

Terms of Agreement and Collaboration Agreement with OvaMed and Falk

In December 2011, we entered into a binding Terms of Agreement with Falk and OvaMed under which we agreed to enter into a collaboration agreement relating to the development of TSO for Crohn’s. In March 2012, the parties entered into the Collaboration Agreement, under which Falk granted us exclusive rights and licenses under certain Falk patent rights, pre-clinical data, and clinical data from Falk’s clinical trials of TSO in Crohn’s, including the ongoing Falk Phase 2 clinical trial, for use in the Territory. In exchange, we granted Falk exclusive rights and licenses to our pre-clinical data and data from clinical trials of TSO in Crohn’s for use in Europe.

In addition, we agreed to pay Falk a total of €5 million after receipt of certain preclinical and clinical data, all of which is expected to be paid by the first half of 2013, and a royalty equal to 1% of net sales of TSO in the Territory.

Under the Collaboration Agreement, a Steering Committee comprised of Coronado, Falk and OvaMed representatives will oversee the TSO development program for Crohn’s, under which Coronado and Falk will each be responsible for clinical testing on approximately 50% of the total number of patients required for regulatory approval of TSO for Crohn’s in the United States and Europe and will share in certain pre-clinical development costs.

The Collaboration Agreement may be terminated by either Falk or Coronado under certain conditions including if the other party fails to cure a material breach under the agreement, subject to prior notice and the opportunity to cure, if the other party is subject to bankruptcy proceedings or if the terminating party terminates all development of TSO.

License Agreement with UCL Business PLC

In November 2007, we entered into a license agreement with UCLB under which we received an exclusive, worldwide license to develop and commercialize CNDO–109 to activate NK cells for the treatment of cancer and related conditions. Under a September 2009 amendment, we also received a non-exclusive license, without the right to sublicense, to certain clinical data solely for use in the IND for CNDO–109.

In consideration for the license, we will be required to make future milestone payments totaling up to approximately $22 million contingent upon the achievement of various milestones related to regulatory events for the first three indications for which CNDO–109 is developed. In March 2012, we recognized our obligation to pay UCLB a $250,000 milestone related to the IND for CNDO–109. In the event that CNDO–109 is commercialized, we will be obligated to pay to UCLB royalties ranging from 3% to 5% of net sales of the product or, if commercialized by a sublicensee, a percentage of certain consideration we receive from such sublicensee (ranging from 20% to 30% of such consideration depending on the stage of clinical development at the time of the sublicense). Under the terms of the agreement, we must use diligent and reasonable efforts to develop and commercialize CNDO–109 activated NK cells worldwide and may grant sublicenses to third parties without the prior approval of UCLB.

The agreement terminates upon the expiration of the last licensed patent right, unless the agreement is earlier terminated. Either party may terminate the agreement in the event of material breach by the other party, subject to prior notice and the opportunity to cure, or in the event the other party enters into bankruptcy or is dissolved for any reasons other than in connection with a merger or acquisition. UCLB may terminate the license agreement if we, or our affiliates, commence or assist in legal proceedings to challenge the validity or ownership of the patents licensed to us under the agreement, or if we market or sell a competing product without UCLB’s prior written consent. In addition, we may terminate the agreement by providing written notice to UCLB at least 30 days’ prior to any contemplated termination.

We have entered into consulting agreements with Dr. Mark Lowdell and UCL Consultants Limited (a wholly-owned subsidiary of UCLB) that provide for Dr. Lowdell to provide various services to us relating to our CNDO–109 program.

Services Agreement with Progenitor Cell Therapy

In April 2010, we entered into a master contract services agreement (the “PCT agreement”), with PCT pursuant to which PCT may, from time to time, provide consulting, preclinical, laboratory and/or clinical research-related services, product/process development services, manufacturing services and other services to us in connection with the CNDO–109 development program. PCT is currently performing services related to the development of manufacturing processes for CNDO–109 under the PCT agreement. We pay for services under the PCT agreement pursuant to statements of work entered into from time to time. Any product resulting from the services performed or product improvement, inventions or discoveries, including new uses for product resulting from the services performed and related patent rights which arise as a result of the services performed by PCT under the PCT agreement are owned solely and exclusively by and assigned to us. Cost of services provided by PCT vary. Through December 31, 2011, we have entered into statements of work with PCT aggregating $1.1 million. This is not an indication of the cost of services we will engage PCT to perform in the future.

Intellectual Property

General

Our goal is to obtain, maintain and enforce patent protection for our product candidates, formulations, processes, methods and any other proprietary technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United States and in other countries. Our policy is to actively seek to obtain, where appropriate, the broadest intellectual property protection possible for our current product candidates and any future product candidates, proprietary information and proprietary technology through a combination of contractual arrangements and patents, both in the United States and abroad. However, patent protection may not afford us with complete protection against competitors who seek to circumvent our patents.

We also depend upon the skills, knowledge, experience and know-how of our management and research and development personnel, as well as that of our advisors, consultants and other contractors. To help protect our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we currently rely and will in the future rely on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all of our employees, consultants, advisors and other contractors to enter into confidentiality agreements that prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

TSO

Under the OvaMed License, we have exclusive rights to United States Patent Nos. 6,764,838, 7,250,173 and 7,833,537, owned by the University of Iowa and licensed by UIRF to OvaMed. These patents claim, respectively, methods of producing a pharmaceutical composition comprising an helminthic parasite preparation, pharmaceutical compositions suitable for oral administration comprising an isolated and purified T. suis helminthic parasite preparation, and methods of treating inflammatory bowel disease, including Crohn’s and UC, in an individual by the administration of a helminthic parasite preparation obtained from a group of helminthic parasites. These patents are scheduled to expire in December 2018, except for the ‘537 patent, which is set to expire about nine months later. Under the patent term restoration provisions of the patent laws, we may choose to restore a portion of the term of one of these patents, or any other relevant patents that may be granted prior to marketing approval of TSO, to recover at least a portion of the delays associated with obtaining regulatory approval. We also have exclusive rights through the OvaMed License under a second patent family owned by UIRF, which is directed to methods of using helminthic parasite preparations to treat patients with a Th1 or Th2 related autoimmune disease. Any patents that mature from this second patent family would not expire until at least November 2023.

Table of Contents

Under the Collaboration Agreement, we have an exclusive license in North America and Japan to Falk’s interest in two patent families: one directed to a process for the preparation of the pharmaceutical product comprised of viable eggs of parasitic helminths and another directed to a method of determining biological activity of embryonated Trichuris eggs. Applications for patents are pending in the United States, Canada and Japan for both patent families.

Our success for preserving market exclusivity for our product candidates relies on our ability to obtain and maintain a regulatory period of data exclusivity over an approved biologic, currently 12 years from the date of marketing approval, and to preserve effective patent coverage. Once any regulatory period of data exclusivity expires, depending on the status of our patent coverage, we may not be able to prevent others from marketing and selling products that are biosimilar to or interchangeable with our product candidates. We are also dependent upon the diligence of third parties, which control the prosecution of pending domestic and foreign patent applications and maintain granted domestic and foreign patents.

In addition to any regulatory exclusivity we may be able to obtain, we also seek to protect additional intellectual property rights such as trade secrets and know-how, including commercial manufacturing processes and proprietary business practices.

CNDO–109

We have exclusive rights to International Patent Application No. PCT/GB2006/000960 and all pending United States and foreign counterpart applications including pending United States Patent Application Serial No. 11/856,466 and the corresponding national phase applications filed in Australia, Canada, Europe, India and Japan, directed to the method of stimulating natural killer cells using CNDO–109 for the treatment of cancer and other conditions. This patent family has been in-licensed on an exclusive basis from UCLB. The CNDO–109 patents that may issue from this patent family would expire in March 2026 in the absence of any patent term extension.

Competition

We operate in highly competitive segments of the biotechnology and biopharmaceutical markets. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Many of our competitors have significantly greater financial, product development, manufacturing and marketing resources than us. Large pharmaceutical companies have extensive experience in clinical testing and obtaining regulatory approval for drugs. In addition, many universities and private and public research institutes are active in cancer research, some in direct competition with us. We also may compete with these organizations to recruit scientists and clinical development personnel. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

We expect TSO, if approved for the treatment of Crohn’s, to compete directly with Centocor Ortho Biotech Inc.’s Remicade (infliximab), UCB S.A.’s Cimzia (certolizumab pegol) and Abbott Laboratories’ Humira (adalimumab), each of which is currently approved for the treatment of various diseases, including IBD, UC and Crohn’s, and several other products. TSO, if developed and approved for the treatment of MS, would compete with Biogen Idec’s Avonex (interferon beta-1a), Bayer Healthcare Pharmaceuticals’ Betaseron (interferon beta-1b), Teva Pharmaceuticals Industries, Ltd.’s Copaxone (Glatiramer Acetate) and Novartis AG’s Gilenya (fingolimod) and several other products. New developments, including the development of other pharmaceutical technologies and methods of treating disease, occur in the pharmaceutical and life sciences industries at a rapid pace.

Each cancer indication for which we are developing products has a number of established therapies with which our candidates will compete. Most major pharmaceutical companies and many biotechnology companies are aggressively pursuing new cancer development programs, including both therapies with traditional, as well as novel, mechanisms of action. Some of the anticipated competitor treatments for AML include Genzyme Corporation’s Clolar (clofarabine), currently approved as a treatment for ALL, Eisai Corporation’s Dacogen (decitabine), currently approved as a treatment for Myelodysplastic Syndromes (“MDS”), Celgene Corporation’s Vidaza (azacitidine), currently approved as a treatment for MDS, and Vion Pharmaceuticals, Inc.’s Onrigin (laromustine) currently being developed as a treatment for AML, any or all of which could change the treatment paradigm of acute leukemia. Each of these compounds is further along in clinical development than is the CDNO–109 activated NK cell product.

Manufacturing

We do not own or operate manufacturing facilities for the production of TSO or CNDO–109 nor do we plan to develop our own manufacturing operations in the foreseeable future. We currently depend on third party contract manufacturers for all of our required raw materials, active pharmaceutical ingredient and finished products for our preclinical and clinical trials. Pursuant to the OvaMed Supply Agreement, we are required to purchase from OvaMed and OvaMed has agreed to manufacture and supply us with clinical and commercial requirements of TSO at pre-determined prices. PCT provides us with clinical services and supplies for CNDO–109. We do not have a contractual arrangement for the manufacture of commercial supplies of CNDO–109.

Manufacturers of our products are required to comply with applicable FDA manufacturing requirements contained in the FDA’s current good manufacturing practice standards (“cGMP”) regulations. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation. Pharmaceutical product manufacturers and other entities involved in the manufacture and distribution of approved pharmaceutical products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved NDA/BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Government Regulation and Product Approval

Government authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing.

United States Pharmaceutical Product Development Process

In the United States, the FDA regulates pharmaceutical (drug and biologic) products under the Federal Food, Drug and Cosmetic Act, and implementing regulations. Pharmaceutical products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable United States requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The process required by the FDA before a pharmaceutical product may be marketed in the United States generally includes the following:

13

Table of Contents

The lengthy process of seeking required approvals and the continuing need for compliance with applicable statutes and regulations require the expenditure of substantial resources and approvals are inherently uncertain.

Products for somatic cell therapy are derived from a variety of biologic sources, including directly harvested autologous, allogeneic, or cultured cell lines. Product safety requires that these sources be well characterized, uniform, and not contaminated with hazardous adventitious agents. Also, cells directly from humans pose additional product safety issues. Because of the complex nature of these products a controlled, reproducible manufacturing process and facility, are required and relied on to produce a uniform product. The degree of reliance on a controlled process varies depending on the nature of the product. Because complete chemical characterization of a biologic product is not feasible for quality control, the testing of the biologic potency receives particular attention and is costly.

Before testing any compounds with potential therapeutic value in humans, the pharmaceutical product candidate enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the pharmaceutical product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including good laboratory practices. The sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA places the IND on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a pharmaceutical product candidate at any time before or during clinical trials due to safety concerns or non-compliance. Accordingly, we cannot be certain that submission of an IND will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such clinical trial.

Clinical trials involve the administration of the pharmaceutical product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by the sponsor. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety. Each protocol must be submitted to the FDA if conducted under a US IND. Clinical trials must be conducted in accordance with the FDA’s good clinical practices requirements. Further, each clinical trial must be reviewed and approved by an independent institutional review board (“IRB”) or ethics committee if conducted outside of the US, at or servicing each institution at which the clinical trial will be conducted. An IRB or ethics committee is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB or ethics committee also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. We intend to use third party clinical research organizations (“CROs”) to administer and conduct our planned clinical trials and will rely upon such CROs, as well as medical institutions, clinical investigators and consultants, to conduct our trials in accordance with our clinical protocols and to play a significant role in the subsequent collection and analysis of data from these trials. The failure by any of such third parties to meet expected timelines, adhere to our protocols or meet regulatory standards could adversely impact the subject product development program.

Table of Contents

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Post-approval studies, or Phase 4 clinical trials, may be conducted after initial marketing approval. These studies are used to gain additional experience from the treatment of patients in the intended therapeutic indication and may be requested by the FDA as a condition of approval.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk for human subjects. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor or, if used, its data safety monitoring board may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB or ethics committee can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s or ethics committee’s requirements or if the pharmaceutical product has been associated with unexpected serious harm to patients.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the pharmaceutical product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the pharmaceutical product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final pharmaceutical product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the pharmaceutical product candidate does not undergo unacceptable deterioration over its shelf life.

United States Review and Approval Processes

The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the pharmaceutical product, proposed labeling and other relevant information are submitted to the FDA as part of an NDA/BLA requesting approval to market the product.

The NDA/BLA review and approval process is lengthy and difficult and the FDA may refuse to approve an NDA/BLA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Even if such data and information is submitted, the FDA may ultimately decide that the NDA/BLA does not satisfy the criteria for approval. If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. Drug manufacturers and their subcontractors are required to register

15

Table of Contents

their establishments with the FDA, and are subject to periodic unannounced inspections by the FDA for compliance with cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. We cannot be certain that we or our suppliers will be able to comply with the cGMP and other FDA regulatory requirements.

Post-Approval Requirements

Any pharmaceutical products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, promoting pharmaceutical products for uses or in patient populations that are not described in the pharmaceutical product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties.

The FDA also may require post-marketing testing, known as Phase 4 testing, risk minimization action plans and surveillance to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.

Orphan Drugs

Under the Orphan Drug Act, special incentives exist for sponsors to develop products for rare diseases or conditions, which are defined to include those diseases or conditions that affect fewer than 200,000 people in the U.S. Requests for orphan drug designation must be submitted before the submission of an NDA or BLA. We intend to request orphan drug designation for CNDO–109 for the treatment of AML.

If a product that has an orphan drug designation is the first such product to receive FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity for that use. This means that, subsequent to approval, the FDA may not approve any other applications to market the same drug for the same disease, except in limited circumstances, for seven years. FDA may approve a subsequent application from another person if the FDA determines that the application is for a different drug or different use, or if the FDA determines that the subsequent product is clinically superior, or that the holder of the initial orphan drug approval cannot assure the availability of sufficient quantities of the drug to meet the public’s need. If the FDA approves someone else’s application for the same drug that has orphan exclusivity, but for a different use, the competing drug could be prescribed by physicians outside its FDA approval for the orphan use, notwithstanding the existence of orphan exclusivity. A grant of an orphan designation is not a guarantee that a product will be approved. If a sponsor receives orphan drug exclusivity upon approval, there can be no assurance that the exclusivity will prevent another person from receiving approval for the same or a similar drug for the same or other uses.

Other Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services (formerly the Health Care Financing Administration), other divisions of the United States Department of Health and Human Services (e.g., the Office of Inspector General), the United States Department of Justice and individual United States Attorney offices within the Department of Justice, and state and local governments.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of reimbursement from third-party payors, including government health administrative authorities, managed care providers, private health insurers and other

16

Table of Contents

organizations. Third-party payors are increasingly examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy, and, accordingly, significant uncertainty exists as to the reimbursement status of newly approved therapeutics. Adequate third party reimbursement may not be available for our products to enable us realize an appropriate return on our investment in research and product development. We are unable to predict the future course of federal or state health care legislation and regulations, including regulations that will be issued to implement provisions of the health care reform legislation enacted in 2010, known as the Affordable Care Act. The Affordable Care Act and further changes in the law or regulatory framework could have a material adverse effect on our business.

International Regulation

In addition to regulations in the United States, there are a variety of foreign regulations governing clinical trials and commercial sales and distribution of any product candidates. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval.

Risks Related to Our Business and Industry

Our product candidates are at an early stage of development and may not be successfully developed or commercialized.

Our two product candidates are in the early stage of development and will require substantial further capital expenditures, development, testing, and regulatory clearances prior to commercialization. Of the large number of drugs in development, only a small percentage successfully complete the FDA regulatory approval process and are commercialized. Accordingly, even if we are able to obtain the requisite financing to fund our development programs, we cannot assure you that our product candidates will be successfully developed or commercialized. If we are unable to develop or receive regulatory approval for or successfully commercialize any of our product candidates, we will not be able to generate product revenues.

Because we in-licensed our product candidates from third parties, any dispute with our licensors or non-performance by us or by our licensors may adversely affect our ability to develop and commercialize the applicable product candidates.

All of our product candidates, including related intellectual property rights, were in-licensed from third parties. Under the terms of our license agreements, the licensors generally have the right to terminate such agreement in the event of a material breach by us. Our licenses require us to make annual, milestone or other payments prior to commercialization of any product and our ability to make these payments depends on our ability to generate cash in the future. These agreements generally require us to use diligent and reasonable efforts to develop and commercialize the product candidate. In the case of TSO, OvaMed licenses TSO from a third party, UIRF, in exchange for annual and milestone payments, patent cost reimbursement, royalties based on sales and diligence obligations. Our rights to TSO are, therefore, also subject to OvaMed’s performance of its obligations to UIRF, any breach of which we may be required to remedy in order to preserve our rights.

If there is any conflict, dispute, disagreement or issue of non-performance between us and our licensing partner regarding our rights or obligations under the license agreement, including any conflict, dispute or disagreement arising from our failure to satisfy payment obligations under such agreement, our ability to develop and commercialize the affected product candidate may be adversely affected. Similarly, any such dispute or issue of non-performance between OvaMed and UIRF that we are unable to cure could adversely affect our ability to develop and commercialize TSO. Any loss of our rights under our license agreements could delay or completely terminate our product development efforts for the affected product candidate.

Table of Contents

Because the results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we advance into clinical trials may not have favorable results in later clinical trials, if any, or receive regulatory approval.

Pharmaceutical development has inherent risk. We will be required to demonstrate through well-controlled clinical trials that our product candidates are effective with a favorable benefit-risk profile for use in their target indications before we can seek regulatory approvals for their commercial sale. Success in early clinical trials does not mean that later clinical trials will be successful as product candidates in later-stage clinical trials may fail to demonstrate sufficient safety or efficacy despite having progressed through initial clinical testing. Companies frequently suffer significant setbacks in advanced clinical trials, even after earlier clinical trials have shown promising results. In addition, only a small percentage of drugs under development result in the submission of an NDA or BLA to the FDA and even fewer are approved for commercialization.

Any product candidates we may advance into clinical development are subject to extensive regulation, which can be costly and time consuming, cause unanticipated delays or prevent the receipt of the required approvals to commercialize our product candidates.

The clinical development, manufacturing, labeling, storage, record-keeping, advertising, promotion, import, export, marketing and distribution of our product candidates are subject to extensive regulation by the FDA in the United States and by comparable health authorities in foreign markets. In the United States, we are not permitted to market our product candidates until we receive approval of a BLA from the FDA. The process of obtaining BLA approval is expensive, often takes many years and can vary substantially based upon the type, complexity and novelty of the products involved. Approval policies or regulations may change and the FDA has substantial discretion in the pharmaceutical approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons. Despite the time and expense invested in clinical development of product candidates, regulatory approval is never guaranteed.

The FDA or and other regulatory agency can delay, limit or deny approval of a product candidate for many reasons, including, but not limited to:

With respect to foreign markets, approval procedures vary among countries and, in addition to the aforementioned risks, can involve additional product testing, administrative review periods and agreements with pricing authorities. In addition, recent events raising questions about the safety of certain marketed pharmaceuticals may result in increased cautiousness by the FDA and comparable foreign regulatory authorities in reviewing new pharmaceuticals based on safety, efficacy or other regulatory considerations and may result in significant delays in obtaining regulatory approvals. Any delay in obtaining, or inability to obtain, applicable regulatory approvals would prevent us from commercializing our product candidates.

Any product candidate we advance into clinical trials may cause unacceptable adverse events or have other properties that may delay or prevent their regulatory approval or commercialization or limit their commercial potential.

Unacceptable adverse events caused by any of our product candidates that we advance into clinical trials could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications and markets. This, in turn, could prevent us from commercializing the affected product candidate and generating revenues from its sale. For example, in phase 1/2 oncology trials, DLT stopping rules are commonly applied. The CNDO–109 phase 1/2 trial is subject to a set of DLTs that could suspend or stop dose escalation by predetermined criteria, including allergic reactions, prolonged aplasia or other organ toxicities of a serious nature.

We have not yet completed testing of any of our product candidates for the treatment of the indications for which we intend to seek product approval in humans, and we currently do not know the extent of adverse events, if any, that will be observed in patients who receive any of our product candidates. If any of our product candidates cause unacceptable adverse events in clinical trials, we may not be able to obtain regulatory approval or commercialize such product or, if such product candidate is approved for marketing, future adverse events could cause us to withdraw such product from the market.

Delays in the commencement of our clinical trials could result in increased costs and delay our ability to pursue regulatory approval.

The commencement of clinical trials can be delayed for a variety of reasons, including delays in:

Any delays in the commencement of our clinical trials will delay our ability to pursue regulatory approval for our product candidates. In addition, many of the factors that cause, or lead to, a delay in the commencement of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate.

Delays in the completion of clinical testing could result in increased costs to us and delay our ability to generate product revenues.

Once a clinical trial has begun, patient recruitment and enrollment may be slower than we anticipate. Clinical trials may also be delayed as a result of ambiguous or negative interim results or difficulties in obtaining sufficient quantities of product manufactured in accordance with regulatory requirements. Further, a clinical trial may be modified, suspended or terminated by us, an IRB, an ethics committee or a data safety monitoring committee overseeing the clinical trial, any clinical trial site with respect to that site, or the FDA or other regulatory authorities due to a number of factors, including:

19

Table of Contents

Changes in regulatory requirements and guidance also may occur and we may need to amend clinical trial protocols to reflect these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for re-examination, which may impact the costs, timing and the likelihood of a successful completion of a clinical trial. If we experience delays in the completion of, or if we must terminate, any clinical trial of any product candidate, our ability to obtain regulatory approval for that product candidate will be delayed and the commercial prospects, if any, for the product candidate may suffer as a result. In addition, many of these factors may also ultimately lead to the denial of regulatory approval of a product candidate.

We rely completely on OvaMed, PCT and other third parties to manufacture our preclinical and clinical pharmaceutical supplies and expect to continue to rely on OvaMed and other third parties to produce commercial supplies of any approved product candidate, and our dependence on third party suppliers could adversely impact our business.

We are completely dependent on third party manufacturers for product supply. In particular, we rely and expect to continue to rely exclusively on OvaMed to supply us with our requirements of TSO. OvaMed is the sole supplier of this product, which it is currently producing at only one facility in Germany, where it also is producing product for clinical trials by third parties, including Falk. If OvaMed becomes unable or unwilling to deliver sufficient quantities of TSO to us on a timely basis and in accordance with applicable specifications and other regulatory requirements, there would be a significant interruption of our TSO supply, which would materially adversely affect clinical development and potential commercialization of the product. Similarly, we rely on BioReliance and PCT for our CNDO–109 requirements and our CNDO–109 clinical program would be adversely affected by a significant interruption in the supply of this product. Furthermore, if OvaMed, BioReliance and/or PCT or any other contract manufacturers cannot successfully manufacture material that conforms to our specifications and with FDA regulatory requirements, we will not be able to secure and/or maintain FDA approval for our product candidates. Our third party suppliers will be required to maintain compliance with cGMPs and will be subject to inspections by the FDA or comparable agencies in other jurisdictions to confirm such compliance. Any delay, interruption or other issues that arise in the manufacture, packaging, or storage of our products as a result of a failure of the facilities or operations of our third party suppliers to pass any regulatory agency inspection could significantly impair our ability to develop and commercialize our products.

We will also rely on our manufacturers to purchase from third-party suppliers the materials necessary to produce our product candidates for our anticipated clinical trials. There are a small number of suppliers for certain capital equipment and raw materials that are used to manufacture our product candidates and, in the case of TSO, OvaMed relies on a single source of ova. We do not have any control over the process or timing of the acquisition of these raw materials by our manufacturers. Moreover, we currently do not have any agreements for the commercial production of these raw materials. Any significant delay in the supply of a product candidate or the raw material components thereof for an ongoing clinical trial could considerably delay completion of our clinical trials, product testing and potential regulatory approval of our product candidates.

We do not expect to have the resources or capacity to commercially manufacture any of our proposed products, if approved, and will likely continue to be dependent upon third party manufacturers. Our dependence on third parties to manufacture and supply us with clinical trial materials and any approved products may adversely affect our ability to develop and commercialize our products on a timely basis or at all.

Table of Contents

We rely on third parties to conduct our clinical trials. If these third parties do not meet our deadlines or otherwise conduct the trials as required, our clinical development programs could be delayed or unsuccessful and we may not be able to obtain regulatory approval for or commercialize our product candidates or at all.

We do not have the ability to conduct all aspects of our preclinical testing or clinical trials ourselves. We intend to use CROs to conduct our planned clinical trials and will rely upon such CROs, as well as medical institutions, clinical investigators and consultants, to conduct our trials in accordance with our clinical protocols. Our future CROs, investigators and other third parties play a significant role in the conduct of these trials and the subsequent collection and analysis of data from the clinical trials.

There is no guarantee that any CROs, investigators and other third parties upon which we rely for administration and conduct of our clinical trials will devote adequate time and resources to such trials or perform as contractually required. If any of these third parties fail to meet expected deadlines, fail to adhere to our clinical protocols or otherwise perform in a substandard manner, our clinical trials may be extended, delayed or terminated. If any of our clinical trial sites terminate for any reason, we may experience the loss of follow-up information on patients enrolled in our ongoing clinical trials unless we are able to transfer the care of those patients to another qualified clinical trial site. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be jeopardized.

If our competitors develop treatments for the target indications of our product candidates that are approved more quickly, marketed more successfully or demonstrated to be more effective than our product candidates, our commercial opportunity will be reduced or eliminated.

We operate in highly competitive segments of the biotechnology and biopharmaceutical markets. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Our product candidates, if successfully developed and approved, will compete with established therapies, as well as new treatments that may be introduced by our competitors. Many of our competitors have significantly greater financial, product development, manufacturing and marketing resources than us. Large pharmaceutical companies have extensive experience in clinical testing and obtaining regulatory approval for drugs. In addition, many universities and private and public research institutes are active in cancer research, some in direct competition with us. We also may compete with these organizations to recruit management, scientists and clinical development personnel. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. New developments, including the development of other pharmaceutical technologies and methods of treating disease, occur in the pharmaceutical and life sciences industries at a rapid pace. Developments by competitors may render our product candidates obsolete or noncompetitive. We will also face competition from these third parties in recruiting and retaining qualified personnel, establishing clinical trial sites and patient registration for clinical trials and in identifying and in-licensing new product candidates.

If we are unable to establish sales and marketing capabilities or fail to enter into agreements with third parties to market, distribute and sell any products we may successfully develop, we may not be able to effectively market and sell any such products and generate product revenue.

We do not currently have the infrastructure for the sales, marketing and distribution of any of our product candidates, and must build this infrastructure or make arrangements with third parties to perform these functions in order to commercialize any products that we may successfully develop. The establishment and development of a sales force, either by us or jointly with a partner, or the establishment of a contract sales force to market any products we may develop will be expensive and time-consuming and could delay any product launch. If we, or our partners, are unable to establish sales and marketing capability or any other non-technical capabilities necessary to commercialize any products we may successfully develop, we will need to contract with third parties to market and sell such products. We may not be able to establish arrangements with third-parties on acceptable terms, if at all.

If any product candidate that we successfully develop does not achieve broad market acceptance among physicians, patients, healthcare payors and the medical community, the revenues that it generates from their sales will be limited.

Even if our product candidates receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors and the medical community. Coverage and reimbursement of our product candidates by third-party payors, including government payors, generally is also necessary for commercial success. The degree of market acceptance of any approved products will depend on a number of factors, including:

If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, hospitals, healthcare payors and patients, we may not generate sufficient revenue from these products and may not become or remain profitable.

We may incur substantial product liability or indemnification claims relating to the clinical testing of our product candidates.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials, and claims could be brought against us if use or misuse of one of our product candidates causes, or merely appears to have caused, personal injury or death. While we have and intend to maintain product liability insurance relating to our clinical trials, our coverage may not be sufficient to cover claims that may be made against us and we may be unable to maintain such insurance. Any claims against us, regardless of their merit, could severely harm our financial condition, strain our management and other resources or destroy the prospects for commercialization of the product which is the subject of any such claim. We are unable to predict if we will be able to obtain or maintain product liability insurance for any products that that may be approved for marketing. Additionally, we have entered into various agreements where we indemnify third parties for certain claims relating to the testing and us of our product candidates. These indemnification obligations may require us to pay significant sums of money for claims that are covered by these indemnifications.

Table of Contents

Healthcare reform and restrictions on reimbursements may limit our financial returns.

Our ability or the ability of our collaborators to commercialize any of our product candidates that may receive the requisite regulatory approval may depend, in part, on the extent to which government health administration authorities, private health insurers and other organizations will reimburse consumers for the cost of these products. These third parties are increasingly challenging both the need for and the price of new drug products. Significant uncertainty exists as to the reimbursement status of newly approved therapeutics. Adequate third party reimbursement may not be available for our product candidates to enable us or our collaborators to maintain price levels sufficient to realize an appropriate return on their and our investments in research and product development.

If we fail to attract and retain key management and clinical development personnel, we may be unable to successfully develop or commercialize our product candidates.

We will need to expand and effectively manage our managerial, operational, financial and other resources in order to successfully pursue our clinical development and commercialization efforts. As a company with a limited number of personnel, we are highly dependent on the development, regulatory, commercial and financial expertise of the members of our senior management, in particular Glenn L. Cooper, M.D. our executive chairman, and Bobby W. Sandage, Jr., Ph.D., our president and chief executive officer. The loss of such individuals or the services of any of our other senior management could delay or prevent the further development and potential commercialization of our product candidates and, if we are not successful in finding suitable replacements, could harm our business. Our success also depends on our continued ability to attract, retain and motivate highly qualified management and scientific personnel and we may not be able to do so in the future due to the intense competition for qualified personnel among biotechnology and pharmaceutical companies, as well as universities and research organizations. If we are not able to attract and retain the necessary personnel, we may experience significant impediments to our ability to implement our business strategy.

We use biological materials and may use hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time consuming or costly.

We may use hazardous materials, including chemicals and biological agents and compounds, that could be dangerous to human health and safety or the environment. Our operations also produce hazardous waste products. Federal, state and local laws and regulations govern the use, generation, manufacture, storage, handling and disposal of these materials and wastes. Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our product development efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials or wastes. We do not carry specific biological or hazardous waste insurance coverage and our property and casualty and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination. Accordingly, in the event of contamination or injury, we could be held liable for damages or penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended.

Our success will depend upon intellectual property, proprietary technologies and regulatory market exclusivity periods, and the intellectual property protection for our product candidates depends significantly on third parties.

Our success will depend, in large part, on obtaining and maintaining patent protection and trade secret protection for our product candidates and their formulations and uses, as well as successfully defending these patents against third-party challenges. UIRF, Falk and OvaMed are responsible for prosecuting and maintaining patent protection relating to their respective patents relating to TSO and UCLB is responsible for prosecuting and maintaining patent protection for CNDO–109, in each case at our expense for our territories. If UIRF, Falk, OvaMed and/or UCLB fail to appropriately prosecute and maintain patent protection for these product candidates, our ability to develop and commercialize these product candidates may be adversely affected and we may not be able to prevent competitors from making, using and selling competing products. This failure to properly protect the intellectual property rights relating to these product candidates could have a material adverse effect on our financial condition and results of operations.

Table of Contents

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or our partners will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following:

In addition to patents, we and our partners also rely on trade secrets and proprietary know-how. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants and advisors, third parties may still obtain this information or come upon this same or similar information independently.

We also intend to rely on our ability to obtain and maintain a regulatory period of market exclusivity for any of our biologic product candidates that are successfully developed and approved for commercialization. Although this period in the United States is currently 12 years from the date of marketing approval, reductions to this period have been proposed. Once any regulatory period of exclusivity expires, depending on the status of our patent coverage and the nature of the product, we may not be able to prevent others from marketing products that are biosimilar to or interchangeable with our products, which would materially adversely affect us.

In addition, United States patent laws may change which could prevent or limit us from filing patent applications or patent claims to protect our products and/or technologies or limit the exclusivity periods that are available to patent holders. For example, on September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law, and includes a number of significant changes to United States patent law. These include changes to transition from a “first-to-invent” system to a “first-to-file” system and to the way issued patents are challenged. These changes may favor larger and more established companies that have more resources to devote to patent application filing and prosecution. The United States Patent and Trademark Office is currently developing regulations and procedures to administer the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act will not become effective until one year or 18 months after its enactment. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will ultimately have on the cost of prosecuting our patent applications, our ability to obtain patents based on our discoveries and our ability to enforce or defend our issued patents.

If we or our partners are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in that litigation would have a material adverse effect on our business.

Our success also depends upon our ability and the ability of any of our future collaborators to develop, manufacture, market and sell our product candidates without infringing the proprietary rights of third parties. Numerous United States and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing products, some of which may be directed at claims that overlap with the subject

Table of Contents

matter of our intellectual property. Because patent applications can take many years to issue, there may be currently pending applications, unknown to us, which may later result in issued patents that our product candidates or proprietary technologies may infringe. Similarly, there may be issued patents relevant to our product candidates of which we are not aware.

There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and biopharmaceutical industries generally. If a third party claims that we or any of our licensors, suppliers or collaborators infringe the third party’s intellectual property rights, we may have to:

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, found to be unenforceable, or interpreted narrowly and could put our patent applications at risk of not issuing. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

We may be subject to claims that our consultants or independent contractors have wrongfully used or disclosed alleged trade secrets of their other clients or former employers to us.

As is common in the biotechnology and pharmaceutical industry, we engage the services of consultants to assist us in the development of our product candidates. Many of these consultants were previously employed at, or may have previously been or are currently providing consulting services to, other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may become subject to claims that we or these consultants have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or their former or current customers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Risks Relating to our Finances, Capital Requirements and Other Financial Matters

We are a development stage company with a history of operating losses that are expected to continue and we are unable to predict the extent of future losses, whether we will generate significant revenues or whether we will achieve or sustain profitability.

We are a company in the development stage and our prospects must be considered in light of the uncertainties, risks, expenses and difficulties frequently encountered by companies in their early stages of operations. We have generated operating losses in all periods since our inception in June 2006, including losses of approximately $3.7 million, $10.0 million, and $36.4 million for the years ended December 31, 2009, 2010 and 2011, respectively. At December 31, 2011, we had an accumulated deficit of approximately $56.6 million. We expect to make

25

Table of Contents

substantial expenditures and incur increasing operating costs in the future and our accumulated deficit will increase significantly as we expand development and clinical trial activities for our product candidates. Our losses have had, and are expected to continue to have, an adverse impact on our working capital, total assets and stockholders’ equity. Because of the risks and uncertainties associated with product development, we are unable to predict the extent of any future losses, whether we will ever generate significant revenues or if we will ever achieve or sustain profitability.

We will need substantial additional funding and may be unable to raise capital when needed, which would force us to delay, curtail or eliminate one or more of our research and development programs or commercialization efforts.

Our operations have consumed substantial amounts of cash since inception. During the years ended December 31, 2009, 2010 and 2011, we incurred research and development expenses of approximately $2.3 million, $8.3 million and $8.6 million, respectively. We expect to continue to spend substantial amounts on product development, including conducting clinical trials for our product candidates and purchasing from contract manufacturers clinical trial materials. We believe that our cash on hand will sustain our operations into the fourth quarter of 2012 and that we will require substantial additional funds to support our continued research and development activities, as well as the anticipated costs of preclinical studies and clinical trials, regulatory approvals and potential commercialization. We have based this estimate, however, on assumptions that may prove to be wrong, and we could spend our available financial resources much faster than we currently expect. Our current financial condition raises substantial doubt about our ability to continue as a going concern.

Until such time, if ever, as we can generate a sufficient amount of product revenue and achieve profitability, we expect to seek to finance future cash needs through equity or debt financings or corporate collaboration and licensing arrangements. We currently have no commitments or agreements relating to any of these types of transactions and we cannot be certain that additional funding will be available on acceptable terms, or at all. If we are unable to raise additional capital, we will have to delay, curtail or eliminate one or more of our research and development programs.

Raising additional funds by issuing securities or through licensing or lending arrangements may cause dilution to our existing stockholders, restrict our operations or require us to relinquish proprietary rights.

To the extent that we raise additional capital by issuing equity securities, the share ownership of existing stockholders will be diluted. Any future debt financing may involve covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, redeem our stock, make certain investments and engage in certain merger, consolidation or asset sale transactions, among other restrictions. In addition, if we raise additional funds through licensing arrangements, it may be necessary to relinquish potentially valuable rights to our product candidates, or grant licenses on terms that are not favorable to us.

If we fail to maintain proper and effective internal control over financial reporting in the future, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, investors’ views of us and, as a result, the value of our common stock.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 and related rules (collectively, “SOX”), for the year ending December 31, 2012, our management will be required to report on, and our independent registered public accounting firm may be required to attest to, the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. To comply with the requirements of being a reporting company under the Securities Exchange Act of 1934 (the “Exchange Act”), we may need to further upgrade our systems, including information technology, implement additional financial and management controls, reporting systems and procedures and hire additional accounting and finance staff.

Historically we did not have sufficient accounting and supervisory personnel with the appropriate level of technical accounting experience and training necessary for, or adequate documented accounting policies and procedures to support effective, internal controls. These material weaknesses contributed to audit adjustments for the years ended December 31, 2010, 2009 and 2008. While we have commenced the process of documenting, reviewing and improving our internal controls over financial reporting for compliance with Section 404 of SOX and have made

26

Table of Contents

efforts to improve our internal controls and accounting policies and procedures, including hiring new accounting personnel and engaging external temporary resources, we may in the future identify deficiencies and weaknesses in our internal controls. If material weaknesses or deficiencies in our internal controls exist and go undetected, our financial statements could contain material misstatements that, when discovered in the future could cause us to fail to meet our future reporting obligations and cause the price of our common stock to decline.

Risks Associated with our Capital Stock

One of our directors and principal stockholders can individually control our direction and policies, and his interests may be adverse to the interests of our other stockholders.

At March 20, 2012, Lindsay A. Rosenwald, M.D., a member of our board of directors, beneficially owned approximately 18.1% of our issued and outstanding capital stock, and certain trusts established for the benefit of Dr. Rosenwald and his family members additionally beneficially owned an aggregate of approximately 7.9% of our issued and outstanding capital stock. By virtue of his holdings and his membership on our board of directors, Dr. Rosenwald may influence the election of the members of our board of directors, our management and our affairs and may make it difficult for us to consummate corporate transactions such as mergers, consolidations or the sale of all or substantially all of our assets that may be favorable from our standpoint or that of our other stockholders.

The market price of our common stock may be volatile and may fluctuate in a way that is disproportionate to our operating performance.

Our stock price may experience substantial volatility as a result of a number of factors, including:

Many of these factors are beyond our control. The stock markets in general, and the market for pharmaceutical and biotechnological companies in particular, have historically experienced extreme price and volume fluctuations. These fluctuations often have been unrelated or disproportionate to the operating performance of these companies. These broad market and industry factors could reduce the market price of our common stock, regardless of our actual operating performance.

The availability of a substantial number of shares for resale may adversely impact any trading market that may develop for our common stock.

Almost all of our 18.6 million outstanding shares of common stock, as well as a substantial number of shares of our common stock underlying outstanding warrants, are available for sale in the public market, either pursuant to Rule 144 under the Securities Act or an effective registration statement. The availability of a substantial number of shares for resale may adversely impact any trading market that may develop for our common stock.

We have never paid and do not intend to pay cash dividends.

We have never paid cash dividends on any of our capital stock and we currently intend to retain future earnings, if any, to fund the development and growth of our business.

None.

Our principal executive offices at 15 New England Executive Park, Burlington, Massachusetts 01803 are occupied under a lease expiring in July 2012 for approximately 600 square feet of space providing for rental payments of approximately $5,200 per month.

We are not involved in any litigation that we believe could have a material adverse effect on our financial position or results of operations. There is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of our executive officers, threatened against or affecting our company or our officers or directors in their capacities as such.

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes thereto and other financial information appearing elsewhere in this Form 10-K.

Overview

We are a biopharmaceutical company focused on the development of novel immunotherapy agents for autoimmune diseases and cancer. Our two principal pharmaceutical product candidates in clinical development are:

We acquired the OvaMed License in January 2011 from Asphelia for an aggregate purchase price of $20.7 million, consisting of 2,525,677 shares of our Series B Convertible Preferred Stock (“Series B Shares”) valued at $6.38 per share, the assumption of promissory notes due to Paramount Credit Partners, LLC (“PCP”) in the amount of $750,000 and the assumption of Asphelia’s obligation to reimburse OvaMed for certain development costs. Of this purchase price $3.8 million was paid in cash, including $3.4 million to OvaMed and $0.4 million for repayment of Asphelia’s debt, including $61,000 to a related party. Under the terms of the OvaMed License, we are required to make annual license payments to OvaMed of $250,000, reimburse patent expenses, make potential future payments totaling up to $5.45 million upon the achievement of various milestones related to regulatory events for the first product, and make additional milestone payments upon the achievement of regulatory events relating to subsequent indications. In the event that TSO is commercialized, we will be obligated to pay annual royalties based upon net sales of the product as well as a portion of certain sublicense revenues. We are also required to purchase our clinical and commercial requirements of TSO from OvaMed at pre-determined prices.

In December 2011, we entered into a binding Terms of Agreement with Falk and OvaMed under which we agreed to enter into a collaboration agreement relating to the development of TSO for Crohn’s. In March 2012, the parties entered into the Collaboration Agreement, under which Falk granted us exclusive rights and licenses under certain

29

Table of Contents

Falk patent rights, pre-clinical data, and clinical data from Falk’s clinical trials of TSO in Crohn’s, including the ongoing Falk Phase 2 clinical trial, for use in the Territory. In exchange, we granted Falk exclusive rights and licenses to our pre-clinical data and data from clinical trials of TSO in Crohn’s for use in Europe and agreed to pay Falk €5 million (approximately $6.5 million), all of which is currently estimated to be paid by the first half of 2013. We also agreed with Falk to share in certain costs relating to the development of TSO for Crohn’s in the United States and Europe.

We acquired an exclusive worldwide license to CNDO–109 in November 2007 from UCLB. In consideration for the license, we paid UCLB initial license fees totaling $0.1 million and are required to make future milestone payments totaling up to $22 million upon the achievement of various milestones related to regulatory events for the first three indications. In March 2012, we recognized our $250,000 milestone obligation to UCLB related to our IND filed in February 2012. If CNDO–109 is commercialized, we will be obligated to pay to UCLB annual royalties based upon net sales of the product or a portion of sublicensing revenues.

On June 30, 2011, we completed a private placement of our Series C Convertible Preferred Stock (“Series C Shares”) which resulted in net proceeds, after placement agent commissions and offering expenses, of approximately $22.9 million.

Critical Accounting Policies and Use of Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this Form 10-K. We believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Research and Development (“R&D”) Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued R&D expenses. This process involves reviewing open contracts and purchase orders, reviewing the terms of our license agreements, communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. The majority of our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples of estimated accrued R&D expenses as of December 31, 2011 include fees to:

Table of Contents

We base our expenses related to clinical studies on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical studies on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows and expense recognition. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual accordingly. Our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in our reporting changes in estimates in any particular period. To date, our estimates have not materially differed from actual costs. Expenses related to annual license fees are accrued on a pro rata basis throughout the year.

Stock-Based Compensation

We expense stock-based compensation to employees over the requisite service period based on the estimated grant-date fair value of the awards and considering estimated pre-vesting forfeiture rates. For stock-based compensation awards to non-employees, we re-measure the fair value of the non-employee awards at each reporting period prior to vesting and finally at the vesting date of the award. Changes in the estimated fair value of these non-employee awards are recognized as compensation expense in the period of change.

Determining the appropriate fair value of stock-based awards requires the use of subjective assumptions. Prior to November 17, 2011 and the absence of a public trading market for our common stock, we conducted periodic assessments of the valuation of our common stock. These valuations were performed concurrently with the achievement of significant milestones or with a significant financing. We use a Black-Scholes option-pricing model to determine the fair value of stock options. The determination of the grant date fair value of options using an option-pricing model is affected by our estimated common stock fair value as well as assumptions regarding a number of other subjective variables. These variables include the fair value of our common stock, our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates, and expected dividends, which are estimated as follows:

31

Table of Contents

The estimation of the number of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period in which estimates are revised. We consider many factors when estimating expected forfeitures, including types of awards, employee class and historical experience. Actual results, and future changes in estimates, may differ substantially from our current estimates.

For the years ended December 31, 2011, 2010, and 2009, stock-based compensation expense was $1.5 million, $2.3 million, and $39,000, respectively. As of December 31, 2011, we had approximately $3.7 million of total unrecognized compensation expense, net of related forfeiture estimates which we expect to recognize over a weighted-average period of approximately 2.2 years.

If any of the assumptions used in a Black-Scholes model changes significantly, stock-based compensation for future awards may differ materially compared with the awards granted previously.

Common Stock Valuations prior to becoming a publicly-traded company

Prior to our becoming a publicly-traded company on November 17, 2011, the fair value of the common stock underlying our stock options, common stock warrants and restricted stock was determined by our board of directors, which intended all options granted to be exercisable at a price per share not less than the per share fair value of our common stock underlying those options on the date of grant. However, certain options granted on October 5, 2010 were granted with an exercise price that was below the fair value of our common stock as determined by an independent valuation as of that date. All other options previously granted or to be granted in the future were granted at the determined grant date fair value. The valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions we use in the valuation model are based on future expectations combined with management judgment. In the absence of a public trading market, our board of directors with input from management exercised significant judgment and considered numerous objective and subjective factors to determine the fair value of our common stock as of the date of each option, restricted stock and warrant grant, including the following factors:

In valuing our common stock, we have used a variety of methodologies that have evolved as the life cycle of our company has progressed. For the underlying valuations of our common stock in periods prior to December 31, 2009, given the early stage of our company and its development programs, we used a cost approach to estimate the fair value of our common stock. The cost approach is based on the premise that an investor would pay no more for an asset than its replacement or reproduction cost. The cost to replace the asset would include the cost of constructing a similar asset of equivalent utility at prices applicable at the time of the valuation

analysis. Under this methodology, a valuation analysis is performed for a company’s identified fixed, financial, intangible and other assets. The derived aggregate fair value of the assets is then netted against the estimated fair value of all existing and potential liabilities, resulting in an indication of the fair value of total equity. This approach was considered an appropriate indication of value as the programs were still in early stages of the development cycle.

As our business and programs evolved, beginning in 2010, we migrated away from the cost approach to a market approach to incorporate the indication of value established through our development efforts and reflected in our Series A share issuances during 2010. Under this approach, the business enterprise value was established based on the contemporaneous equity offerings. Pursuant to the AICPA Guidelines, an option pricing method was used to value the shares using a contingent claims analysis, which applies a series of call options whose inputs reflect the liquidation preferences and conversion behavior of the different classes of equity. The value of the common stock was then derived by analyzing the fair value of these options. After the equity value of the business enterprise was determined, the total equity value of any equity instruments such as preferred stock, stock options, restricted stock and warrants outstanding and the concluded common stock value on a converted basis is allocated. Next, the option pricing method was used to allocate the residual equity value (inclusive of any infusion of cash from in-the-money options and warrants) to the common stock of the company. Since our shares were not publicly traded, a discount for lack of marketability was applied. This lack of marketability discount was estimated to be 10% prior to becoming a publicly-traded company, valuations, using a theoretical put option model that captures the cost to ensure stock could be sold at the price prevailing at the valuation date after the time required to finding a market, or the time until an expected liquidity event. The put option model considers the expected time to a liquidity event, estimated volatility based on peer company data, risk free interest rates and management judgment. The ultimate fair values of our common stock were used as an input in determining the fair value of the warrants, restricted stock and stock options at various periods of time.

Results of Operations

General

To date, we have not generated any revenues from operations and, at December 31, 2011, we had an accumulated deficit of $56.6 million primarily as a result of R&D expenses, purchase of in-process research and development and general and administrative (“G&A”) expenses. While we may in the future generate revenue from a variety of sources, including license fees, milestone payments, research and development payments in connection with strategic partnerships and/or product sales, our product candidates are at an early stage of development and may never be successfully developed or commercialized. Accordingly, we expect to continue to incur substantial losses from operations for the foreseeable future and there can be no assurance that we will ever generate significant revenues.

R&D Expenses

Conducting research and development is central to our business. For the years ended December 31, 2009, 2010 and 2011, R&D expenses were $2.3 million, $8.3 million, $8.6 million, respectively, and such expenses were $24.5 million for the period from inception (June 28, 2006) to December 31, 2011. R&D expenses consist primarily of:

33

Table of Contents

We expect to continue to incur substantial expenses related to our research and development activities for the foreseeable future as we continue product development. Since product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials, we expect that our R&D expenses will increase in the future. In addition, if our product development efforts are successful, we expect to incur substantial costs to prepare for potential commercialization of any late-stage product candidates and, in the event one or more of these product candidates receive regulatory approval, to fund the launch of the product. From inception through December 31, 2011, direct, external development costs incurred for our CNDO–109 product development program were $4.4 million, including $0.4 million, $2.1 million, and $1.9 million respectively, for the years ended December 31, 2009, 2010 and 2011. From inception through December 31, 2011, direct, external development costs incurred for our TSO product development program were $2.9 million, excluding $20.7 million of in-process research and development costs related to our acquisition of the asset in 2011. Our results of operations for the years ended December 31, 2009, 2010 and 2011 include direct, external development costs incurred in connection with two product development programs that have been discontinued. From inception through December 31, 2011, such expenses totaled $5.2 million.

G&A Expenses

G&A expenses consist principally of personnel-related costs, professional fees for legal, consulting, audit and tax services, rent and other general operating expenses not otherwise included in R&D. For the years ended December 31, 2009, 2010 and 2011, G&A expenses were $0.3 million, $0.9 million, and $5.8 million, respectively, and such expenses were $7.6 million from inception through December 31, 2011. We anticipate G&A expenses will increase in future periods, reflecting continued and increasing costs associated with:

Table of Contents

R&D expenses increased $242,000, or 3%, from the year ended December 31, 2010 to the year ended December 31, 2011. This increase was primarily due to $2.5 million of external development costs related to TSO, including a milestone-related charge of $1.5 million relating to the filing of an IND for TSO and $0.6 million of increased consulting expenses, severance-related costs, and other general expenses, primarily offset by a $1.4 million decrease in stock-based compensation expense related to the 2010 vesting of restricted common stock issued to non-employees in 2007, a $1.2 million decrease in development costs related to discontinued product candidates and a $0.3 million decrease in CNDO–109 development costs. Payment of the milestone to OvaMed is due in the fourth quarter of 2012. We expect our R&D expenses to increase in future quarters as we commence our clinical programs for TSO and CNDO–109 and for the contractual payments to Falk of approximately $6.5 million, all of which is currently expected to be paid by the first half of 2013.

G&A expenses increased $4.9 million from the year ended December 31, 2010 to the year ended December 31, 2011, reflecting the substantial increase in the level of our business activity during 2011 and transition to a public company. The increase in G&A expenses to support these activities consisted primarily of a $1.9 million increase in professional fees, consisting of legal and accounting fees, a $1.3 million increase in personnel costs, $0.5 million in increased stock compensation expense, and $0.4 million increase in consulting and outside services.

In January 2011, we acquired from Asphelia a sublicense and related agreements for TSO and assumed certain liabilities of Asphelia. As consideration for such acquisition, we issued 2,525,677 Series B shares valued at $6.38 per share, assumed the PCP Note of $750,000 and made cash payments totaling $3.8 million, including $3.4 million to OvaMed and $0.4 million for repayment of Asphelia’ s debt, including $61,000 to a related party. The total consideration paid in connection with the acquisition of Asphelia’s assets, including the assumption of certain liabilities of Asphelia, was $20.7 million, which was recorded as in-process research and development expense in 2011.

In 2011, we incurred $74,000 of interest expense related to the PCP Note. Interest expense of $1,535,000 in 2010 related to an aggregate of $9.9 million of debt which was either repaid or converted to our Series A shares between April 2010 and December 2010.

The increase in interest income in 2011 compared to the same period last year was primarily due to higher cash balances.

Warrant expense of $1,407,000 in 2011 is a noncash expense relating to the marking-to-market of the warrants for Series C shares issued to the placement agent for their services in connection with the Series C financing. A warrant liability of $1,286,000 was established at June 30, 2011 upon the issuance of the warrants. This liability was valued for a final time at $2,693,000 on November 15, 2011 upon the effectiveness of our resale registration statement on Form S-1. The expense represents the change in value from June 30, 2011 to November 15, 2011. This liability was reclassified to equity upon effectiveness of the Form S-1.

NM—Not meaningful

R&D expenses increased $6.1 million from the year ended December 31, 2009 to the year ended December 31, 2010. This increase was primarily attributable to $2.3 million higher non-cash charges for stock-based compensation, $2.2 million higher salaries and administrative costs associated with increased staffing and related overhead costs, $1.7 million higher expenses related to the technology transfer for CNDO–109 to a GMP environment, and $0.3 million higher costs relating to our two discontinued product development programs.

35

Table of Contents

G&A expenses increased $0.6 million from the year ended December 31, 2009 to the year ended December 31, 2010. This increase is primarily attributable to higher legal, accounting and other professional expenses and increased personnel-related costs due to increased staffing to support our product development programs and establish and infrastructure to support growth.

Interest income was $61,000 for the year ended December 31, 2010. There was minimal interest income for the year ended December 31, 2009. The interest income in 2010 was primarily attributable to cash balances resulting from the proceeds of our Series A shares issued in April 2010.

Other income of $0.7 million for the year ended December 31, 2010 reflects the government grant received by us under the Therapeutic Discovery Project. This income will not be recurring.

Interest expense, net includes interest on our senior notes, related party notes and the amortization of costs associated with charges for the issuance of debt. For the year ended December 31, 2010 total interest expense, was $1.5 million, compared with $1.1 million for the year ended December 31, 2009. $0.8 million in 2010 related to the amortization of the embedded conversion feature of the senior convertible and related party notes, partially offset by reduced interest expense on this debt that converted to Series A Shares in April 2010.

Liquidity and Capital Resources

To date, we have funded our operations through the sale of debt and equity securities aggregating $52.1 million of net proceeds. At December 31, 2011, we had cash and cash equivalents of $23.2 million. On June 30, 2011, we completed a private placement of our Series C Shares which resulted in net proceeds, after placement agent commissions and offering expenses, of approximately $22.9 million.

We expect to incur substantial expenditures in the foreseeable future for the research, development and potential commercialization of our product candidates. We will require additional financing to develop, prepare regulatory filings and obtain regulatory approvals, fund operating losses, and, if deemed appropriate, establish manufacturing, sales and marketing capabilities. We have funded our operations to date primarily through the sale of equity and debt. We believe that our current cash and cash equivalents are sufficient to fund operations into the fourth quarter of 2012 based on our current business plan. Our current financial condition raises substantial doubt about our ability to continue as a going concern. Our failure to raise capital as and when needed would have a material adverse impact on our financial condition and our ability to pursue our business strategies. We will seek funds through equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing. Adequate additional funding may not be available to us on acceptable terms or at all. If adequate funds are not available to us, we will be required to delay, curtail or eliminate one or more of our research and development programs.

As of December 31, 2010, all notes and other debt was either repaid or converted into our Series A Shares. At December 31, 2011, we had outstanding $750,000 of promissory notes due to PCP which we assumed from Asphelia. These notes are due in December 2013 or earlier in the event of a merger transaction.

On November 15, 2011, our resale registration statement on Form S-1 became effective. Upon effectiveness, all of our then outstanding Series A Shares, Series B Shares and Series C Shares automatically converted into shares of our common stock on a one-to-one basis, resulting in an 11,496,186 share increase in our outstanding common stock and an increase in additional paid in capital of $66,993,000. After the conversion, we had 18,524,185 shares of common stock outstanding. Additionally, upon effectiveness of the Form S-1, our 461,263 outstanding warrants for Series C Shares became exercisable for common stock. As of November 15, 2011, we determined the fair value of these warrants to be $2,693,000, a $1,407,000 increase from the original valuation of $1,286,000 at June 30, 2011, and during the year ended December 31, 2011, recorded this increase in warrant liability as a noncash charge. The final warrant liability of $2,693,000 was reclassified to additional paid in capital.

Cash Flows for the Three Years Ended December 31, 2011, 2010 and 2009

Operating Activities

Net cash used in operating activities increased $5.3 million from the year ended December 31, 2010 to the year ended December 31, 2011. The increase in net loss of $26.3 million, included $1.4 million related to the increase to the fair value of the Series C warrant liability and $1.6 million related to the increase in accounts payable and accrued expenses, offset by $20.7 million of noncash expense for in-process research and development expense related to the Asphelia asset purchase, a $0.9 million decrease in stock-based compensation and a $0.9 million decrease in the change in fair value of a warrant-embedded conversion feature.

Cash used in operating activities increased $3.3 million from the year ended December 31, 2009 to the year ended December 31, 2010 primarily due to increased operating expenses partially offset by the $0.7 million government grant received in 2010.

Investing Activities

Net cash used in investing activities was $3.8 million in 2011 and consisted solely of cash payments related to the Asphelia asset purchase.

Cash used in investing activities for the years ended December 31, 2010 and 2009 was not significant.

Financing Activities

Net cash provided by financing activities in the year ended December 31, 2011 of $23.1 million consisted of $22.9 million of net proceeds from issuance of the Series C Shares and $193,000 from exercise of employee stock options.

Cash provided by financing activities increased $15.2 million from the year ended December 31, 2009 to the year ended December 31, 2010 primarily due to the issuance of our Series A Shares which resulted in net proceeds of $19.4 million in 2010, while the primary source of cash from financing activities in 2009 was $3.9 million from net debt proceeds.

Contingent Contractual Payments

Based on our development plans and license agreements in effect as of December 31, 2011, we have committed to make potential future milestone payments to our licensors upon achievement of certain development or regulatory milestones. Under the OvaMed License for TSO, the milestone payments aggregate approximately $5.45 million, including $1.5 million relating to the achievement of the milestone for the filing of an IND for TSO, for the first indication and $2.0 million for each subsequent indication. Under the UCLB license for CNDO–109, the milestone payments aggregate approximately $22 million for the first three indications. We incurred a milestone-related charge of $1.5 million in the three month period ended December 31, 2011 relating to the filing of an IND for our first indication for TSO. Payment for this milestone to OvaMed is due in the fourth quarter of 2012. In addition, as a result of the Collaboration Agreement entered into in March 2012, we have committed to pay Falk €5 million (approximately $6.5 million based on exchange rates effective on December 31, 2011), all of which is estimated to be paid by the first half of 2013. Additionally, under employment agreements with certain of our executive officers, such officers are entitled to cash bonuses based on our common stock satisfying certain market capitalization, trading volume and other criteria.

Off-Balance Sheet Arrangements

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts.

Quantitative and Qualitative Disclosures about Market Risks

We held no marketable securities at December 31, 2010 and 2011. Our existing debt is at a fixed rate and we currently do not have exposure to foreign currency fluctuations.

Net Operating Loss Tax Carry-Forwards

As of December 31, 2011, we had net federal operating loss carryforwards of approximately $27.9 million to offset future federal income taxes which expire beginning in 2026. Current federal and state tax laws include substantial restrictions on the utilization of net operating loss and tax credits in the event of an ownership change. Even if the carryforwards are available, they may be subject to substantial annual limitations, due to ownership change limitations provided by the Internal Revenue Code of 1986 as amended, or IRC and similar state provisions. At December 31, 2010 and 2011, we recorded a 100% valuation allowance against our deferred tax assets, as our management believes it is more likely than not that they will not be fully realized. If we determine in the future that we will be able to realize all or a portion of our net operating loss carryforwards, an adjustment to our net operating loss carryforwards would increase net income in the period in which we make such a determination.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness, as of December 31, 2011, of the design and operation of our disclosure controls and procedures, as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based on this evaluation, our principal executive officer and principal financial officer have concluded that, as of such date, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Internal Control Over Financial Reporting

Management’s Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting refers to the process designed by, or under the supervision of, our principal executive officer and principal financial officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:

(1) Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

(2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorization of our management and directors; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of our assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Management is responsible for establishing and maintaining adequate internal control over financial reporting for our company.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness, as of the end of the period covered by this report, of our disclosure controls and procedures, as such term is defined in Exchange Act Rule 13a-15(e). Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective.

This Annual Report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the Company’s registered public accounting firm due to a transition period established by rules of the Securities and Exchange Commission for newly public companies.

Changes in Internal Controls over Financial Reporting.

There has been no change in our internal control over financial reporting during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Coronado Biosciences, Inc.

(a development stage enterprise)

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of changes in convertible preferred stock and stockholders’ equity (deficit) and of cash flows present fairly, in all material respects, the financial position of Coronado Biosciences, Inc. and its subsidiary (a development stage enterprise) at December 31, 2011 and December 31, 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011 and, cumulatively, for the period from June 28, 2006 (date of inception) to December 31, 2011 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has incurred recurring losses and negative cash flows from operations since inception and will require additional financing to fund future operations. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
