Our Product Candidate

Nimacimab

We completed the acquisition of Bird Rock Bio, Inc. (“Bird Rock”), a privately held, clinical-stage biotechnology company, in August 2023. Through this transaction, we acquired nimacimab, a humanized IgG4 negative allosteric modulating ("NAM") antibody that specifically binds to the CB1 receptor with no cross-reactivity to certain other GPCRs, including cannabinoid receptor 2 ("CB2").

Unmet Need and Market Opportunity

Obesity is a complex, heterogeneous, chronic, and progressive disease, which substantially affects health, quality of life and mortality. "Obesity" and "severe obesity" are defined by a body mass index ("BMI") of greater than 30 and 40 kg/m2, respectively, with abnormal or excessive fat accumulation. "Overweight" is defined by a BMI of greater than 25 kg/m2. Obesity and overweight states are characterized by a chronic energy surplus in which the body’s energy intake exceeds its energy expenditure and are often associated with excess and chronic inflammation of adipose and other tissues. Other stressors and environmental factors contribute to this chronic imbalance. Today, obesity is the fifth-leading risk factor cited by the World Health Organization ("WHO") for contributing as a primary cause of death globally. Based on estimates by the WHO, globally, obesity affected more than 890 million adults as of 2022, and we believe it has continued to increase in prevalence worldwide since the WHO declared a global obesity epidemic in 1997. In addition, the WHO estimates that 2.5 billion adults were overweight as of 2022. Current estimates by the World Obesity Atlas suggest that 54% of the global population will be overweight or obese by 2035, compared to 46% in 2025. In addition, it is estimated that 39% of, or 770 million, children between the ages of five and nineteen years of age will be overweight or obese by 2035 compared to 28% of, or 550 million, such children in 2025. Based on several analyst estimates, we believe this deeply rooted global health crisis could represent a total addressable market of more than $100 billion annually by 2030. Previous treatments for obesity have been limited by safety concerns and insufficient efficacy, which we believe hindered their success. However, incretin-based therapeutics have shown significant weight loss and positive cardiovascular effects in clinical studies. While glucagon-like peptide-1 ("GLP-1") receptor agonists have been effective in reducing overall body weight, this weight loss also includes, on average, an estimated 25-40% loss of lean muscle mass. Patients using GLP-1 therapies also face tolerability issues, particularly gastrointestinal discomfort, which can affect the duration of treatment and lead to high rates of discontinuation. Moreover, even for those patients who can tolerate therapy there are still up to 15% of these patients that lose less than 5% of weight at three months of treatment and are considered non-responders. Despite the remarkable efficacy and commercial success of GLP-1 therapies, we believe there is still potential to improve the quality and sustainability of weight loss regimens, as well as, help patients who can not tolerate or do not respond to GLP-1 therapies. We believe the combination of non-incretin mechanisms, such as nimacimab, with incretin therapies like GLP-1s could improve outcomes compared to solely using incretin therapies. Alternatively, we believe a non-incretin mechanism could be used as a follow-up to standard GLP-1 treatments or as an alternative for specific patient groups with obesity and overweight.

Role of CB1 in the Treatment of Obesity and Other Metabolic Conditions

The CB1 receptor is one of the most abundant receptors in the endocannabinoid system ("ECS"), playing a significant role both in the central nervous system ("CNS") and peripheral tissues. In the CNS, the CB1 receptors are involved in motor control, cognition, emotional regulation, and hunger cues. However, CB1 receptors are also highly prevalent in peripheral tissues, including the liver, kidney, adipose tissue (fat cells), pancreas, and gastrointestinal tract. Notably, the role of CB1 in peripheral tissues is crucial for metabolic regulation. In adipose tissue, for example, activation of CB1 receptors is closely linked to the promotion of fat storage, making it a key target for obesity-related therapies. In the kidney, CB1 signaling helps regulate blood flow, which is essential for waste filtration and maintaining electrolyte balance and blood pressure. In the liver, CB1 plays a critical role in regulating lipid metabolism and glucose homeostasis. Additionally, activation of CB1 receptors in the gastrointestinal tract influences the release of neurotransmitters and hormones that regulate appetite, gastric motility, and nutrient absorption. Given its widespread influence on metabolic processes in peripheral tissues, targeting CB1 outside the CNS represents a promising therapeutic strategy for improving metabolic health and addressing obesity.

Building on the diverse roles of CB1 receptors in peripheral tissues, the "CB1 axis" emerges as a critical pathway for metabolic regulation, linking the activation of CB1 receptors across various organs to the broader control of energy balance and metabolic function. The distribution and function of the CB1 axis provides a strong rationale to target this critical physiological system as a therapeutic to treat different pathological states. Moreover, dysregulation of the CB1 axis in peripheral tissues has been associated with metabolic disorders such as obesity and kidney disease. Recent research highlights that inhibiting CB1 outside the brain can influence leptin sensitivity and adipocyte signaling, directly impacting fat cell physiology. Activation of CB1 promotes fat accumulation and disrupts mitochondrial function in obesity models, whereas inhibiting CB1 enhances mitochondrial biogenesis. This metabolic adjustment results in weight loss through heightened energy expenditure, increased lipolysis, and fatty acid oxidation processes, particularly in brown adipose tissue.

CB1 Inhibition: Small Molecule Clinical Experience and New Approaches

It has been previously demonstrated that inhibiting the CB1 receptor can significantly reduce weight in patients with obesity. In 2006, Sanofi (formerly Sanofi-Aventis) developed a small molecule CB1 inverse agonist called rimonabant, which demonstrated 10% or greater weight loss after one year, in 25.2% of patients receiving 20 mg of rimonabant. Despite being approved by the European Medicines Agency, the drug was soon taken off the market due to severe adverse neuropsychiatric side effects, including suicidal ideation. Since rimonabant was taken off the market, a significant amount of research was conducted to better understand why rimonabant failed. Ultimately it was determined that rimonabant, a small molecule, readily entered the brain, resulting in severe adverse neuropsychiatric side effects.

A new generation of small molecule CB1 inhibitors are being developed with the aim of minimizing inhibition of CB1 receptors in the brain and maximizing exposure in the peripheral tissues. These new generation small molecule CB1 inverse agonists have been modified to discourage distribution in the CNS and brain by increasing the polarity of surface residues, which also impacts membranous trafficking and bioavailability. While these altered small molecules yield notable reductions in CNS distribution relative to non-biased small molecules such as rimonabant, its presence and significant CB1 occupancy in the brain has still been noted in chronic preclinical and clinical settings. Phase 2 data related to this new generation of small molecules resulted in dose-dependent mild to moderate adverse neuropsychiatric side effects, such as irritability, anxiety and sleep disturbances, confirming that these molecules continue to cross the blood-brain barrier when dosed at levels required to achieve desired levels of weight loss.

We believe that the safest and most effective way to inhibit CB1 is with a large-molecule approach to potentially eliminate safety concerns from the molecule penetrating the blood-brain barrier. We believe nimacimab, as a large molecule, has the potential to mitigate safety concerns associated with the CB1 class due to our ability to administer higher doses of nimacimab, without significant concentrations of nimacimab penetrating the blood-brain barrier.

Nimacimab Product Differentiation

Weight loss continues to be the primary endpoint to evaluate efficacy in patients with obesity and overweight. However, we recognize, through our engagement with key advisors and healthcare providers, that the obesity and overweight market is heterogeneous and that different patients may need different therapies to manage their condition(s). As these markets grow, we believe there is an increasing demand from healthcare providers for alternative therapies to treat obesity and other metabolic conditions, along with their associated comorbidities. While the current GLP-1 drugs are efficacious, we believe there is room to optimize dosing regimens, develop drugs with more favorable side effect profiles, and build upon the current mechanisms to re-establish healthy metabolic pathways.

The current incretin mimetic drugs approved for weight loss act primarily through caloric restriction by increasing GLP-1 in the gut and signaling to the CNS feelings of satiety or fullness. While caloric restriction is an effective way to manage weight loss, it has been shown that caloric restriction alone, without appropriate lifestyle intervention, will lead to loss of lean mass. For example, based on clinical trial data for semaglutide, a GLP-1 agonist, on average 25-40% of the weight loss results from the loss of lean mass (which can include both muscle and bone). In addition, up to 70% of patients experience gastrointestinal ("GI") side effects with semaglutide including nausea, vomiting, constipation and diarrhea, which can lead to discontinuation of treatment in some cases.

We believe nimacimab stands apart from GLP-1s and other incretin-based weight loss therapies because its primary mechanism goes beyond suppression of food intake. While peripheral CB1 inhibition can reduce elevated leptin levels as well as modulate appetite-regulating hormones to broadly blunt appetite, key additional drivers of weight loss include increased energy expenditure, fat metabolism, and insulin sensitivity as well as reduced inflammation. As a result, clinical data from this class of drugs have demonstrated not only weight loss but also lean mass preservation, improved insulin sensitivity, and reductions in cholesterol. Additionally, preclinical obesity models using CB1 inhibitors have shown improvements in hyperleptinemia, leptin sensitivity, and increased energy expenditure. This unique mechanism offers a potential alternative, and even complementary, approach to chronic weight management, broadening therapeutic options for patients with obesity and overweight.

Nimacimab’s Differentiation Within the CB1 Class

Within the CB1 inhibitor class, we believe nimacimab is distinct from competing drug candidates primarily because it is a large-molecule antibody and has a distinct mechanism of noncompetitive inhibition that collectively confers several advantages over the small molecules in development.

1.Enhanced Selectivity and Safety - As an antibody, nimacimab exhibits high specificity for CB1, reducing the risk of off-target toxicity—a critical factor given the historical safety concerns with CB1 inhibition. Our Phase 1 and Phase 2a studies established the potential for nimacimab’s favorable safety profile, with no observed neuropsychiatric adverse effects and excellent GI tolerability, a key differentiation from previous CB1-targeting drugs.

Table of Contents

2.Negative Allosteric Modulation - Nimacimab functions as a negative allosteric modulator of CB1, which means it binds to a distinct area of CB1 'away' from the receptor’s primary active site (the orthosteric site) and thus inhibits CB1 activity without any competition from the endogenous ligands (endocannabinoids). We believe this noncompetitive mode of action is distinct from small-molecule inhibitors, which target CB1 receptor’s orthosteric site and require successful competition with endocannabinoids for receptor occupancy to inhibit CB1 signaling. We believe this can become critical as CB1 signaling is often overactive in metabolic diseases, and direct competition with an inhibitor that binds at the orthosteric site and competes with endocannabinoids for binding to the receptor may be insufficient in tissues with excessive CB1 activity. In such disease states, where both CB1 receptor density and endocannabinoid levels are elevated, orthosteric small molecules must outcompete high concentrations of endocannabinoids, which can negatively impact their Pharmacodynamic ("PD") profile and ultimately limit their efficacy.

3.Inverse Agonism - As described above, nimacimab is a noncompetitive inhibitor which we believe confers specific advantages. Additionally, nimacimab can inhibit CB1 without an agonist present in which case it can drive the opposite signaling of CB1 agonists such as promoting increased cAMP and reducing b-arrestin recruitment. Thus, nimacimab inhibits CB1 as both a noncompetitive antagonist and an inverse agonist.

4.Superior Dosing and PK Profile - Small-molecule CB1 inhibitors require daily oral dosing, which increases systemic exposure and potential toxicity risks. Nimacimab, with its 18-22 day half-life, supports once-monthly subcutaneous dosing, enhancing patient compliance while maintaining consistent receptor inhibition.

5.Potential for Combination Therapies - The antibody format opens opportunities for combinations with therapeutics targeting orthogonal and/or distinct mechanistic pathways using bi- or tri-specific bioconjugation approaches. Combining a more tolerable dose of a GLP-1 agonist (to drive caloric restriction) with a safe CB1 inhibition mechanism (to drive fat metabolism) could yield additive or even synergistic weight loss effects. Our Phase 2a study includes an exploratory arm evaluating the combination of Wegovy (semaglutide) with Nimacimab to assess this potential.

Summary of Preclinical Data

The CB1 pathway is clinically validated to drive weight loss and has many supporting studies that highlight peripheral mechanisms to promote productive metabolic changes, including weight loss. We endeavored to understand if nimacimab could drive weight loss using a diet-induced obesity ("DIO") mouse model. Since nimacimab does not cross-react with mouse CB1, a transgenic mouse was generated which targeted the murine CB1 ("mCB1") loci for insertion of human CB1 ("hCB1"). This targeted disruption of mCB1 for hCB1 knockin mice was confirmed genetically as well as functionally, as measured by productive CB1 signaling in a THC-induced hyperthermia model as well as the ability to generate obese mice with a high fat diet ("HFD") with similar kinetics and magnitude of weight gain. We found that the use of nimacimab in this mouse DIO model demonstrated the following:

•significant dose-dependent weight loss compared to vehicle;

•significant fat mass loss with lean mass preservation; and

•dose-dependent glycemic improvements

Furthermore, an additional preclinical mouse DIO study provided further evidence for the potential combination of nimacimab with incretins and demonstrated the potential durability of response with nimacimab as a monotherapy or maintenance therapy post-incretin treatment. This preclinical mouse DIO study demonstrated that at day 25 the combination of nimacimab and a suboptimal tirzepatide dose (3nmol/kg daily) yielded 44% vehicle-adjusted weight loss (29.6% weight loss). The combination outperformed either agent alone with nimacimab demonstrating 21.5% vehicle-adjusted weight loss (7.1% weight loss) and the suboptimal tirzepatide dose demonstrating 29.7% vehicle-adjusted weight loss (15.4% weight loss). The combination efficacy also exceeded an optimal dose of tirzepatide (10 nmol/kg), which resulted in 38.9% vehicle-adjusted weight loss (24.6% weight loss). The preclinical mouse DIO study also demonstrated that, when used as a monotherapy, nimacimab-driven weight loss persisted for about 20 days after treatment cessation, while mice treated with tirzepatide alone regained most of their lost weight within a week post-treatment. Lastly, the preclinical mouse DIO study demonstrated that when nimacimab alone was used after an initial tirzepatide or combination treatment in the preclinical mouse DIO mouse model, it reduced rebound weight gain in these groups of mice.

In addition to clinical data sets from monlunabant and rimonabant, we believe these DIO data support the hypothesis that peripheral CB1 inhibition is sufficient for weight loss while central CB1 inhibition is not required for metabolic improvements such as weight loss.

Nonclinical Data

Two Investigational New Drug Applications ("IND")-enabling nonclinical studies with nimacimab were completed in non-human primates, which demonstrated a strong safety profile with a no adverse effect level ("NOAEL") of 75 mg/kg with bi-weekly dosing for 26 weeks. In addition, nimacimab was shown in two independent non-human primate biodistribution studies to have almost no exposure in the brain (~0.02%), with multi-dose studies demonstrating no accumulation.

A 3-week subcutaneous injection toxicity study in cynomolgus monkeys was completed to determine the toxicity and toxicokinetic ("TK") profile of two dose levels of 25 mg/kg and 75 mg/kg of nimacimab versus a matching placebo, following two subcutaneous ("SC") injections two weeks apart. In this study, no mortality occurred and there were no effects noted on clinical signs, ophthalmology, electrocardiography, hematology, clinical chemistry, coagulation and urinalysis during the course of the study. There were no nimacimab effects noted on organ weights, and no nimacimab-related macroscopic or microscopic observations.

Subsequently, a repeat-dose toxicity study was conducted in cynomolgus monkeys at two dose levels of 40 mg/kg and 75 mg/kg nimacimab versus matching placebo to determine the toxicity and TK profile of nimacimab administered every two weeks over 26 weeks (13 total doses), and to assess the reversibility of any changes following an eight week recovery period. In this study, nimacimab was well-tolerated with results similar to the three week study with the only nimacimab-related macroscopic or microscopic observations consisting of reversible minimal to moderate inflammation at the injection site. In general, the TK of nimacimab indicates slow absorption from subcutaneous injection sites, low systemic clearance, a limited volume of distribution and a long terminal half-life. Based on the results of these studies, the NOAEL was considered to be the high dose of 75 mg/kg/dose.

Two non-human primate studies were conducted to further elucidate the CNS exposure of nimacimab. The first study dosed cynomolgus monkeys with nimacimab at 3mg/kg and 40 mg/kg and collected cerebral spinal fluid ("CSF") at multiple timepoints as a surrogate measure for CNS exposure. This data demonstrated that nimacimab has almost no exposure with little to no accumulation in the brain. A second study evaluated direct CNS exposure by performing a biodistribution study with radiolabeled nimacimab. Nimacimab was radiolabeled with 124-Iodine, and after confirmation of expected in vitro potency, administered intravenously ("IV") to 2 rhesus monkeys with positron emission tomography ("PET") scans were acquired for 30 minutes at 6 and 24 hours post-injection. Overall, animals showed lower signals in the heart, lung, liver, spleen and kidney at 24 hours compared to 6 hours. No significant uptake of nimacimab was observed in the brain at the time points studied.

Taken together, we believe these nonclinical studies demonstrate that nimacimab is safe, with an NOAEL of 75 mg/kg, and that very little, if any, nimacimab enters the CNS.

Clinical Development History of Nimacimab

Summary of Completed Phase 1 Studies

In June 2017, Bird Rock initiated a Phase 1b study. The purpose of the study was to evaluate the safety and tolerability of multiple doses of nimacimab after four weeks of dosing in subjects with non-alcoholic fatty liver disease ("NAFLD"), now known as metabolic-associated steatotic liver disease ("MASLD"). Secondary objectives included determination of pharmacokinetics of nimacimab for multiple doses and to determine levels of anti-drug antibodies ("ADA") after dosing with nimacimab. The study was carried out in subjects who had baseline MASLD. This was done to enable the preliminary assessment of biomarkers of liver disease with short term therapy. We believe the short duration of treatment, small number of patients in each cohort and lack of any dietary restrictions should be taken into account when considering the results.

In Part A of this study, 24 healthy volunteers were randomized to receive a single dose of either placebo or single ascending doses of nimacimab (0.6, 1.2 or 2.5 mg/kg). In Part B of this study, 82 patients with pre-diabetes or diabetes and MASLD were randomized to receive either placebo or multiple escalating doses of nimacimab (0.6, 1.2 or 2.5 mg/kg) once a week for four weeks. There were no deaths, serious adverse events ("SAEs") or treatment-emergent adverse events ("TEAEs") that lead to discontinuation. All TEAEs were graded as mild to moderate in intensity except for one severe TEAE (dizziness) in the nimacimab 0.6 mg/kg dose group determined to have not been related to study drug. The majority of TEAEs were not related to study drug and there was no apparent relationship between the dose level and the type, severity, or incidence of the TEAEs.

For all subjects at all doses, concentrations of nimacimab were quantifiable in serum by 0.5 hours after the first dose and remained quantifiable in most subjects through the last time point, day 67. Exposure to nimacimab as measured by AUC and Cmax increased with increasing doses of nimacimab. At all dose levels, median Tmax ranged from 0.5 to 2 hours and mean t1/2 ranged from 18 to 22 days.

Immunogenicity was assessed in all subjects throughout the study. Only two subjects had consistently elevated titers over multiple time points of ADA. This data suggest that nimacimab has an overall low immunogenicity profile.

Table of Contents

The placebo group in the Phase 1 study had an increase in weight while the treatment groups showed stable weight resulting in a numerical difference that represents an early trend for potential efficacy. Decreases in mean alanine transaminase ("ALT") and aspartate aminotransferase ("AST") were observed during the study in the active treatment groups, but not in the placebo group. Numeric decreases in ELF score and statistically significant reduction in hyaluronic acid ("HA") was observed in the 1.2 mg/kg dose group compared to placebo (p=0.02). Assessment of serum lipids indicated a dose-dependent trend towards reduction of low-density lipoprotein cholesterol (LDL-c) starting from Day 29; on Day 67 there was a mean 8.9 mg/dL decrease in LDL-c in the 2.5 mg/kg dose group compared with a mean 8.3 mg/dL increase in the placebo group (p=0.0073). No effect was observed in total cholesterol, high-density lipoprotein cholesterol (HDL-c), and triglycerides. No significant treatment effect was observed on liver fat percentage, de-novo lipogenesis, inflammatory biomarkers and OGTT test.

Full study data was presented at the European Association for the Study of Diabetes ("EASD") Annual Meeting in September 2025.

Summary of Phase 2a Study

In October 2025, we announced the results from our CBeyond Phase 2a proof-of-concept clinical trial of nimacimab administered as a subcutaneous injectable for the treatment of obesity and overweight in the United States. CBeyond is a randomized, placebo- and active-controlled, double-blind Phase 2a trial that enrolled 136 adults with obesity or overweight, including individuals with a BMI ≥27 kg/m² with at least one comorbidity. Patients were randomized across four arms, 2:2:1:1 to arms with weekly nimacimab 200 mg subcutaneously, placebo, nimacimab 200 mg plus semaglutide (Wegovy®), or placebo plus semaglutide, and were dosed weekly for 26 weeks. Patients not participating in a 26-week extension were monitored for 13 weeks post-treatment. We reported the following 26 week data from the CBeyond Phase 2a study :

•The nimacimab monotherapy arm did not achieve the primary endpoint of weight loss compared to placebo (-1.52% vs. -0.26 for placebo, mITT). Preliminary pharmacokinetic analysis suggested an association between exposure and response, indicating that the 200 mg, subcutaneous weekly dose was suboptimal as a monotherapy.

•At the tested dose and exposure levels, nimacimab 200 mg demonstrated a favorable safety profile with placebo-like tolerability. In combination with semaglutide, there was no increase in gastrointestinal (GI) adverse events. Importantly, there were no increases in neuropsychiatric adverse events reported resulting from treatment with nimacimab.

•In the combination arm, nimacimab 200 mg, subcutaneous weekly dose plus semaglutide demonstrated a clinically meaningful magnitude of weight loss compared to semaglutide alone (-13.2% vs -10.25%, p=0.0372, mITT), with no plateau being observed through Week 26. In the combination arm, 100% of patients achieved greater than 5% weight loss (vs. 85% with semaglutide alone) and 67% achieved greater than 10% weight loss (vs. 50% with semaglutide alone) based on the per protocol analysis. This finding supports potential further studies to evaluate combinations of nimacimab and incretin-based therapies, like semaglutide or tirzepatide. Other findings in the combination arm included:

◦Nimacimab plus semaglutide showed a change of -11.26cm (1.16cm) in waist circumference versus -8.09cm (1.2cm) for semaglutide alone, resulting in a difference of -3.17cm (1.59cm) (p=0.0492, using least-squares mean (LSM)).

◦An improvement in lean mass to fat mass ratio was observed at week 26 when comparing the nimacimab plus semaglutide combination arm to the placebo arm (0.26 vs. 0.02, p <0.0001), and the combination arm compared to semaglutide alone (0.26 vs. 0.13, p = 0.0126).

◦A decrease in rebound weight gain in an analysis of participants 12 weeks post-treatment when nimacimab 200 mg (subcutaneous, weekly) was combined with semaglutide when compared to semaglutide alone (17.8% versus 37.3% weight rebound). Moreover, at 12 weeks post-treatment, the nimacimab plus semaglutide group maintained significant weight loss compared to the placebo group (p=0.006), while the semaglutide alone group lost significance over the placebo group (p=0.12) and followed a trajectory of rebound weight gain consistent with previously reported data (Wilding et al., 2022, STEP-1 Trial Extension), which demonstrated that patients will gain a majority of weight back within 1-year of stopping treatment with semaglutide.

Topline data from our CBeyond Phase 2a study was presented at ObesityWeek medical conference in November 2025.

Summary of Phase 2a Extension Study

Patients who completed 26 weeks of treatment in the Phase 2a study were eligible to enroll in a 26-week extension for a potential full treatment duration of 52 weeks with a 13-week follow-up period. A total of 43 patients were enrolled, with 19 and 24 patients in the combination and monotherapy cohorts, respectively. In the combination arms, continued with blinded treatment with nimacimab or placebo and continued receiving semaglutide (Wegovy®). Patients in the monotherapy arm received nimacimab 300 mg during the extension.

In February 2026, the Company reported the following interim results from the combination cohort of its Phase 2a extension study:

•19 participants in the combination cohorts completed week 26 were eligible for, and enrolled in the extension study, which continued in a blinded manner for 26 weeks, maintaining their original treatment assignment (10 nimacimab plus semaglutide; 9 placebo plus semaglutide). An additional 22 participants completed week 26 and were either ineligible for the extension or chose not to join the extension study and continued on post-treatment follow-up (11 nimacimab plus semaglutide; 11 placebo plus semaglutide).

•Of the 10 participants in the nimacimab plus semaglutide arm who joined the extension study, the mean weight loss at 26 weeks was 14.4%. 7 participants completed the additional 26 weeks of treatment and lost an additional 7.9% of weight, resulting in a mean weight loss of 22.3% after 52 weeks of treatment. According to initial results in this limited cohort, the combination therapy remained safe and well tolerated. No SAEs or AESIs were reported during the extension period.

•Of the 9 participants in the placebo plus semaglutide arm that joined the extension study, mean weight loss at 26 weeks was -13.9%. 7 participants completed treatment of the additional 26 weeks and lost an additional -5.8% of weight during the extension period, resulting in a mean weight loss of -19.7% after 52 weeks of treatment.

Full topline reporting of the CBeyond Phase 2a extension data including nimacimab monotherapy data and 13-week off-therapy follow-up is expected to take place in the third quarter of 2026.

Clinical Development Plan

In March 2026, we initiated an expansion study (Part C) of the CBeyond Phase 2a trial to assess preliminary safety and pharmacokinetic (PK) profile of nimacimab administered intravenously (IV). The expansion study will comprise two cohorts of nimacimab monotherapy (400 mg IV and 600 mg IV) compared to placebo administered weekly over 15 weeks (16 doses), with a 12 week follow up period, to generate preliminary monotherapy safety, PK, and exploratory efficacy data. Within each dose cohort, 8 participants will be randomized in a 3:1 ratio to nimacimab (n=6) or placebo (n=2). We expect to report topline data from the expansion study in the fourth quarter of 2026.

We have received comments from the agency regarding our Type C meeting request in which they responded to our proposed Phase 2b clinical trial design, we intend to use data from the CBeyond trial, including the CBeyond expansion study (Part C), to inform the design of a potential Phase 2b study and potential registration path for nimacimab as a combination therapy with GLP-1s. Key design elements under evaluation include patient selection, dose selection, treatment duration, and endpoints. Final trial design and timing remain subject to ongoing data analysis, regulatory feedback and capital considerations.

Competition

The biopharmaceutical and pharmaceutical industries are intensely competitive and characterized by rapid technological progress. In general, competition among pharmaceutical products is based in part on product efficacy, safety, reliability, availability, price and patent position. An important factor is the relative timing of the market introduction of our products and our competitors’ products. Accordingly, the speed with which we can develop products, complete clinical trials and approval processes and supply commercial quantities of the products to the market impacts our competitiveness. Our competitive position also depends upon our ability to show differentiation with a product that is either more efficacious, particularly in the relevant target populations, offers a better safety or tolerability profile, is less expensive or quicker to manufacture, or represents a combination of these advantages. We also depend upon our ability to attract and retain qualified personnel, obtain patent protection or otherwise develop proprietary products or processes and secure sufficient capital resources for the often substantial period between technological conception and commercial sale. While we believe that our knowledge, experience and scientific resources provide us with competitive advantages, we face competition from major pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions, among others.

If nimacimab is approved for the indications for which we expect to conduct clinical studies, it will compete with the foregoing therapies and currently marketed drugs, as well as any drugs potentially in development. It is also possible that we will face competition from other pharmaceutical approaches as well as other types of therapies. The key competitive factors affecting the success of our program, if approved, is likely to be its efficacy, safety, differentiation, convenience, price, level of generic competition, and availability of reimbursement. Despite significant biopharmaceutical industry investment, no therapy targeting CB1 has been approved for the treatment of obesity in the US.

Large and established pharmaceutical companies are developing GLP-1 agonists or combinations with other incretin-mimetics, which compete in the same market as our product candidates. These companies generally have greater experience and resources to support their research and development efforts, conduct testing and clinical trials, obtain regulatory approvals to market products, manufacture such products on a broad scale and market approved products. These companies also have significantly greater research and marketing capabilities than we do and may also have products that have been approved or are in late stages of development and have collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the products that we develop obsolete. We also face competition from smaller companies who, like us, rely on investors to fund research and development and compete for co-development and licensing opportunities from large and established pharmaceutical companies. Regarding the use of nimacimab to target peripheral inhibition of CB1 for the treatment of obesity and metabolic conditions, our direct competition includes monlunabant, a small molecule CB1 receptor inverse agonist.

Other companies are targeting proteins associated muscle preservation and growth with the aim of complementing the GLP-1 agonists by improving lean mass preservation. While many of these drugs are in the same stage of development, they have a different and potentially more difficult regulatory path than nimacimab. Based on the recent FDA guidance, companies who wish to receive marketing approval for lean mass preservation must obtain acceptance from the FDA as to the appropriate primary endpoints, while the FDA guidance for drugs approved for weight loss in the overweight and obese population remains unchanged and clearly defined.

The development and commercialization of therapies for the treatment of obesity and overweight is highly competitive. Our product candidate, nimacimab, if approved, will face significant competition, including from well-established, currently marketed therapies that have been developed by large, well-known pharmaceutical companies, and our failure to demonstrate a meaningful improvement to the existing standard of care may prevent us from achieving significant market penetration. In particular, there is intense competition in the obesity and overweight field, especially with the advent of GLP-1 RAs, such as Wegovy, marketed by Novo Nordisk, and Zepbound, marketed by Eli Lilly. In addition to injectable therapies for overweight and obesity, Wegovy became the first FDA approved oral GLP-1 receptor agonist in December 2025 and other oral therapies are in development for treating overweight and obesity, including those being development by Eli Lilly, Structure Therapeutics, and Viking Therapeutics. There are numerous other companies that have commercialized or are developing treatments for obesity and overweight that we will compete with. Competitors to nimacimab that are targeting peripheral inhibition of CB1 for the treatment of obesity and metabolic conditions include Novo Nordisk and their development effort of monlunabant. We face competition from these companies and other major pharmaceutical and biotechnology companies, including specialty pharmaceutical companies, academic institutions, governmental agencies and public and private research institutions, among others. Refer to "Risks Related to Commercialization — We face significant competition from entities that have made substantial investments into developing novel treatment for patients with obesity and overweight, including large pharmaceutical companies with approved therapies in our current indications, and biopharmaceutical, specialty pharmaceutical and biotechnology companies developing novel treatments and technology platforms. If the companies develop competing technologies or product candidates more rapidly than we do or their technologies are more effective, our ability to develop and successfully commercialize products may be adversely affected" in our Risk Factors section for additional information.

Manufacturing

We do not own or operate manufacturing facilities and we rely on third-party contract manufacturing organizations (“CMOs”) to supply nimacimab for our pre-clinical and clinical studies. Nimacimab, a monoclonal antibody, is produced under current good manufacturing practices (“cGMP”) through recombinant DNA technology, leveraging established upstream cell culture processes and downstream purification methods. The resulting drug substance is formulated and filled into pre-filled syringes by our third-party partners.

To meet anticipated clinical and commercial needs, we are making a substantial investment in our manufacturing infrastructure through these CMOs. Key activities include:

•Formulation Optimization: We are evaluating multiple formulations aimed at improving patient convenience.

•Process Optimization: We continue to optimize our manufacturing to evaluate modifications to both our upstream and downstream processes to improve product yield. The activities are aligned with our goals to establish a commercial manufacturing process that is reliable and repeatable at large commercial scales.

•Device Strategy: We are exploring new delivery platforms for nimacimab, with a view towards improving patient experience and adherence in later-stage clinical studies and eventual commercial distribution.

12

We believe that our collaborative approach with leading CMOs and other partners involved in our chemistry, manufacturing and controls ("CMC") operations, positions us to reliably meet future clinical and commercial demand for nimacimab and further optimize its potential for the treatment of obesity, overweight, and related metabolic disorders.

Halozyme License Agreement

In December 2025, the Company entered into a Non-exclusive Global Collaboration and License Agreement (the “Halozyme License Agreement”) with Halozyme, Inc. (“Halozyme”).

Under the terms of the Halozyme License Agreement, Halozyme granted the Company a non-exclusive license to Halozyme’s ENHANZE® drug delivery technology for the development of a subcutaneous co-formulation with nimacimab (such combination, the “Product”). Halozyme will also be the Company’s exclusive supplier of clinical and commercial supplies of the active pharmaceutical ingredient ("API") for Halozyme’s rHuPH20 bulk drug product.

Among other considerations, the Company will make milestone payments to Halozyme tied to achievement of certain development and commercialization milestone events with respect to the Product, as well as milestone payments based on achievement of certain net sales levels of the Product. The Company will also make mid-single digit royalty payments based on worldwide net sales of the Product. To date, none of such milestones has been achieved.

The Halozyme License Agreement became effective in December 2025 and, unless earlier terminated, will continue until the expiration of the royalty term for the applicable product in each country, which begins upon the first commercial sale of the product in such country and continues until the last valid patient claim covering the product in that country or the length of time specified in the Halozyme License Agreement. The Halozyme License Agreement also includes customary termination rights, representations and warranties, covenants and indemnification obligations for a transaction of this nature.

Intellectual Property

The success of our product candidates will depend in large part on our ability to obtain and maintain patent and other legal protection for the proprietary technology, inventions and improvements we consider important to our business, prosecute our patent applications and defend any issued patents we obtain, preserve the confidentiality of our trade secrets, and operate without infringing the patents and proprietary rights of third parties. We strive to protect the proprietary technologies that we believe are important to our business, including seeking and maintaining patent protection intended to cover the compositions of matter of our product candidates, their methods of use, related technologies, and other inventions that are important to our business. We employ a comprehensive approach to intellectual property protection and obtaining patent protection is not the only method that we utilize to protect our proprietary rights and technologies. We also rely upon trade secrets and know-how and continuing technological innovation to develop and maintain our proprietary and intellectual property position. We seek to protect our proprietary information in part using confidentiality agreements with our collaborators, scientific advisors, employees and consultants, and invention assignment agreements with our employees and selected consultants, scientific advisors and collaborators. The confidentiality agreements are designed to protect our proprietary information and, in the case of agreements or clauses requiring invention assignment, to grant us ownership of technologies that are developed through a relationship with a third party.

As of March 1, 2026, we owned three granted U.S. patents, 30 granted foreign patents, including granted patents in Europe, Japan, Korea and China, as well as other commercially relevant jurisdictions, and 10 pending U.S. and foreign patent applications directed to the compositions of matter for the nimacimab antibody and molecular variants, and to methods of treatment and uses of nimacimab and its variants for treating a number of diseases responsive to the modulation of the CB1 receptor, including obesity and related metabolic conditions. The patents, and, if issued, the patent(s) resulting from the pending patent applications will expire between 2035 and 2036, excluding any potential available patent term adjustment or patent term extension.

The use of nimacimab in therapeutic doses and methods for treating obesity and weight related comorbidities is further covered in two international (PCT) patent applications owned by us and from which we expect to file U.S. and other national-phase patent applications in commercially relevant jurisdictions. If issued, the patent(s) resulting from the pending applications have an expiration date of no earlier than 2045, excluding any potential patent term adjustment or patent term extension.

The use of nimacimab in a method of predicting whether a patient is at risk for developing Fast Progressing Renal Disease ("FPRD") and treating patients to avoid such risks is further covered in pending applications in the United States, Europe, Japan and Korea, as well as other commercially relevant jurisdictions. These claims are directed towards methods of diagnosing FPRD and towards treatment of patients suffering from FPRD with nimacimab. If issued, the patent(s) resulting from the pending application have an expiration date of no earlier than 2043, excluding any potential patent term adjustment or patent term extension.

Government Regulation

Government authorities in the United States, at the federal, state and local level, and in other countries, extensively regulate, among other things, the research, development, testing, manufacture, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, import and export of pharmaceutical products such as those we are developing.

The processes for obtaining regulatory approvals in the United States and in foreign countries, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources. A failure to comply with such laws and regulations or prevail in any enforcement action or litigation related to noncompliance could have a material adverse impact on our business, financial condition and results of operations and could cause the market value of our common stock to decline.

Review and approval of drugs and biologics in the United States

In the United States, the Food and Drug Administration ("FDA") regulates drugs under the Federal Food, Drug and Cosmetic Act (the "FDCA"), and its implementing regulations, and regulates biologics under the FDCA, the Public Health Service Act (the "PHSA"), and their implementing regulations. The process required by the FDA before new drug and biologic product candidates may be marketed in the United States generally involves the following:

•completion of nonclinical or preclinical laboratory tests and formulation studies conducted in accordance with Good Laboratory Practice regulations ("GLPs"), and other applicable regulations, which studies can include animal studies;

•submission to the FDA of an IND, which must become effective before human clinical trials may begin;

•approval by an independent institutional review board ("IRB"), or ethics committee at each clinical site before each trial may be initiated;

•performance of adequate and well-controlled human clinical trials in accordance with Good Clinical Practice regulations ("GCPs") to evaluate the safety and effectiveness of a proposed drug candidate, and the safety, purity and potency of a proposed biological product candidate, for its intended use;

•preparation and submission to the FDA of a New Drug Application ("NDA"), for a drug or a Biologics License Application ("BLA") for a biologic, after completion of all pivotal trials;

•a determination by the FDA within 60 days of its receipt of an NDA or BLA to file the application for review;

•satisfactory completion of an FDA advisory committee review, if applicable;

•satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug or biologic is produced to assess compliance with current Good Manufacturing Practice requirements ("cGMPs"), to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;

•satisfactory completion of potential inspection of selected clinical investigation sites to assess compliance with GCPs; and

•FDA review and approval of the NDA or BLA to permit commercial marketing of the product for particular indications for use in the United States.

Once a product candidate is identified for development, it enters the preclinical testing stage. Preclinical tests, which can include animal studies, include laboratory evaluations of product chemistry, toxicity and formulation. An IND sponsor must submit, among other things, the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of an IND. An IND is a request for authorization from the FDA to administer an investigational product to humans. An IND will also include a protocol detailing, among other things, the objectives of the clinical trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated, if the trial includes an efficacy evaluation. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, places the IND on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during clinical trials due to safety concerns or non-compliance with FDA requirements, in which case clinical trials may not begin or continue until the FDA notifies the sponsor that the hold has been lifted. The FDA may also place a trial on a partial clinical hold. A partial clinical hold is a delay or suspension of only part of the clinical work requested or ongoing under the IND. No more than 30 days after imposition of a clinical hold or partial clinical hold, the FDA will provide the sponsor a written explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation (or full investigation in the case of a partial clinical hold) may only begin or resume after the FDA has notified the sponsor that the investigation may proceed.

14

Clinical trials involve the administration of the investigational product to humans under the supervision of qualified investigators in accordance with GCP requirements. This includes the requirement that all research subjects/patients provide their informed consent in writing for their participation in any clinical trial. Clinical trials must be conducted under protocols detailing, among other things, the objectives of the trial, dosing procedures, subject selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol for each clinical trial must be submitted to the FDA as part of the IND, and a separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. While the IND is active, progress reports summarizing the results of the clinical trials and nonclinical studies performed since the last progress report, among other information, must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and investigators for serious and unexpected suspected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs or biologics, findings from animal or in vitro testing suggesting a significant risk to humans, and any clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the protocol or investigator brochure. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information.

Furthermore, an independent IRB or ethics committee at each institution participating in the clinical trial must review and approve each protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form that must be provided to each trial subject or his or her legal representative, monitor the study until completed and otherwise comply with IRB regulations. The FDA or the sponsor 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 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 requirements or if the investigational product has been associated with unexpected serious harm to patients. In addition, some clinical trials are overseen by an independent group of qualified experts organized by the sponsor, known as a data safety monitoring board or committee. Depending on its charter, this group may determine whether a trial may move forward at designated check points based on access to certain data from the trial. There are also requirements governing the registration of certain clinical trials and reporting of clinical trial results to public registries, including clinicaltrials.gov.

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

•Phase 1: The product candidate is initially introduced into healthy human subjects or, in certain indications, patients with the target disease or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early indication of its effectiveness and to determine maximal dosage.

•Phase 2: The product candidate is administered to a limited patient population with a specified disease or condition to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy and safety of the product candidate for specific targeted diseases, and to determine dosage tolerance and optimal dosage.

•Phase 3: The product candidate is administered to the established patient population expected to benefit based upon the risk/benefit profile. Generally, this phase of studies are conducted at geographically dispersed clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the efficacy and safety of the product for approval, to establish the overall risk-benefit profile of the product, and to provide adequate information for the labeling of the product.

Post-approval trials, sometimes referred to as Phase 4 studies, may be conducted after initial regulatory approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA or BLA.

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

15

NDA and BLA review and approval process

Assuming successful completion of all required testing in accordance with applicable regulatory requirements, the results of the product development, including among other things, results from nonclinical and clinical studies, together with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of an NDA or BLA requesting approval to market the product for one or more indications. The NDA or BLA must include all relevant data available from preclinical and clinical studies, including negative or ambiguous results as well as positive findings, among other things. The submission of an NDA or BLA requires payment of a substantial user fee to the FDA, and the sponsor of an approved NDA or BLA is also subject to an annual program fee. A waiver of certain user fees may be obtained under certain limited circumstances.

The FDA conducts a preliminary review of all NDAs and BLAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may refuse to file any NDA or BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the NDA or BLA must be resubmitted with the additional information requested before FDA will review the application. Once filed, the FDA reviews a BLA to determine, among other things, whether the product is safe, pure and potent for its intended use, and an NDA to determine, among other things, whether the drug is safe and effective for its intended use. As part of the NDA and BLA review, the FDA also evaluates whether the manufacturing of the products is cGMP-compliant to assure and preserve the product's identity, strength, quality and purity.

Under the Prescription Drug User Fee Act ("PDUFA"), guidelines that are currently in effect, the FDA has a goal of reviewing and responding to a standard submission within ten months from the date of the “filing” of an original NDA or BLA to review and act on the submission. This review typically takes twelve months from the date the NDA or BLA is submitted to the FDA because the FDA has approximately two months to make a “filing” decision. The FDA does not always meet its PDUFA goal dates, however, and the review process can be significantly extended by the FDA requests for additional information or clarification, the applicant's submission of additional information, or other reasons.

The FDA may refer an application for a novel biologic or drug to an advisory committee. The FDA may also refer to the advisory committee certain scientific questions raised by an application. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and may provide a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

During its review of an NDA or BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. Additionally, within the review period and before approving a BLA or NDA, the FDA will likely inspect one or more clinical trial sites to assure compliance with GCPs and the integrity of the clinical data submitted. After evaluating the NDA or BLA and all related information, including the advisory committee recommendation, if any, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in some cases, a complete response letter ("CRL"). A CRL generally contains a statement of specific conditions that must be met to secure final approval of the NDA or BLA and may require additional clinical or nonclinical testing in order for the FDA to reconsider the application. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA’s satisfaction, the FDA will typically issue an approval letter for the NDA or BLA. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications.

If the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product's labeling; require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the product's safety or effectiveness or safety, purity, and potency after approval; require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, including a risk evaluation and mitigation strategy ("REMS"), which can materially affect the potential market and profitability of the product. If the FDA concludes a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS in connection with the application. The FDA will not approve the application without an approved REMS, if one is required. The REMS could include medication guides, physician communication plans, assessment plans, and/or elements to assure safe use, such as restricted distribution methods, patient registries, or other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of commercial products.

16

In addition, the Pediatric Research Equity Act ("PREA") requires a sponsor to conduct pediatric clinical trials for most biologics and drugs. Under PREA, original NDAs and BLAs (and certain supplements) for a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration must contain a pediatric assessment or reports on the molecularly targeted pediatric cancer investigation, unless the sponsor has received a deferral or waiver or an exception applies. The required assessment must evaluate the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations, and support dosing and administration for each pediatric subpopulation for which the product is deemed safe and effective. The sponsor may request, or the FDA may grant, a deferral of pediatric clinical trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that the drug or biologic is ready for approval for use in adults before pediatric clinical trials are complete or that additional data needs to be collected before the pediatric clinical trial begins.

Expedited development and review programs

The FDA has a number of programs intended to expedite the development or review of a marketing application for an investigational product. For example, the fast track designation program is intended to expedite or facilitate the process for developing and reviewing product candidates that meet certain criteria. Specifically, investigational drugs and biologics are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. The sponsor of a fast track product candidate has opportunities for more frequent interactions with the applicable FDA review team during product development and, once a marketing application is submitted, the application may be eligible for priority review. With regard to a fast track product candidate, the FDA may consider for review sections of the application on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the applications and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA or BLA.

A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and review. A product candidate can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product candidate, alone or in combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product candidate, including involvement of senior managers.

Any product candidate submitted to the FDA for approval, including a product candidate with a fast track designation or breakthrough designation, may also be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. An NDA or BLA is eligible for priority review if the product candidate is designed to treat a serious condition, and if approved, would provide a significant improvement in safety or efficacy compared to available therapies. The FDA will attempt to direct additional resources to the evaluation of an NDA or BLA designated for priority review in an effort to facilitate the review. The FDA endeavors to review applications with priority review designations within six months of the filing date as compared to ten months for review of original NDAs or BLAs under its current PDUFA review goals.

In addition, a product candidate may be eligible for accelerated approval. A product candidate intended to treat serious or life-threatening diseases or conditions may be eligible for accelerated approval upon a determination that the product candidate has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA generally requires that a sponsor of a biologic receiving accelerated approval perform adequate and well-controlled confirmatory clinical trials, and may require that such confirmatory trials be underway prior to granting accelerated approval. Products receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor fails to conduct the required confirmatory trials in a timely manner or if such trials fail to verify the predicted clinical benefit. In addition, the FDA currently requires as a condition of accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product.

Fast track designation, breakthrough therapy designation, priority review, and accelerated approval do not change the standards for approval, but may expedite the development or approval process. Even if a product candidate qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

17

Post-Approval Requirements

Drugs and biologics manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion, and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims are subject to FDA review and approval prior to implementation. There also are continuing annual program fees for any marketed products and the establishments at which such products are manufactured, as well as new application fees for supplemental applications with clinical data.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP requirements and impose reporting and documentation requirements upon the sponsor and any third party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

•restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•fines, warning letters or holds on post-approval clinical trials;

•refusal of the FDA to approve pending NDAs, BLAs or supplements to approved NDAs or BLAs, or suspension or revocation of product licenses or approvals;

•product seizure or detention, or refusal to permit the import or export of products;

•consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;

•mandated modification of promotional materials and labeling and the issuance of corrective information;

•issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or

•injunctions or the imposition of civil or criminal penalties.

In addition, the FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs and biologics may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may legally prescribe commercially-available products for uses that are not described in the product's labeling and that differ from those tested by use and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of such physicians in their choice of treatments. The FDA does, however, restrict manufacturers' communications on the subject of off-label use of their products.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act ("PDMA"), which regulates the distribution of drugs and drug samples at the federal level and sets minimum standards for the registration and regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution.

18

Combination Products

Certain of our product candidates, may be comprised of components, such as drug components and biologic components, that would normally be regulated under different regulatory pathways, regulatory authorities, and frequently by different centers at the FDA. In addition, our injectable product candidates are being developed together with an injector device, which will render them combination products with a device component. We also are focusing our development efforts on at least one product candidate as a therapy intended to be used in combination with GLP-1 receptor agonists (and potentially other anti-obesity therapies). Even where such therapies are not physically combined or co-packaged with our product candidates, seeking approval for use in combination may require additional clinical and nonclinical evidence and could increase development time, cost, and regulatory risk.

Specifically, under regulations issued by the FDA, a combination product may include:

•a product comprised of two or more regulated components that are physically, chemically, or otherwise combined or mixed and produced as a single entity;

•two or more separate products packaged together in a single package or as a unit and composed of drug and device products, device and biological products, biological and drug products or biological products, drug products and device products;

•a drug, or device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for use only with an individually specified drug, or device, or biological product where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product, the labeling of the other product would need to be updated (e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose); or

•an investigational drug, or device, or biological product packaged separately that according to its proposed labeling is for use only with another individually specified investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

Under the FDCA and its implementing regulations, the FDA is charged with assigning a center with primary jurisdiction, or a lead center, for review of a combination product. The designation of a lead center generally eliminates the need to receive approvals from more than one FDA center for combination products, although it does not preclude consultations by the lead center with another FDA center. The determination of which center will be the lead center is based on the “primary mode of action” of the combination product. The FDA has established an Office of Combination Products to address issues regarding combination products and provide more certainty to the regulatory review process. This office is responsible for developing guidance and regulations to clarify the regulation of combination products, and for assigning the FDA center that will have primary jurisdiction for review of a combination product where the jurisdiction is unclear or in dispute.

Following approval of a combination product, each component of a combination product retains its regulatory status (as a biologic, drug or device, for example) and is subject to the requirements established by the FDA for that type of component. Combination products require coordination within the FDA for review of each of their components (e.g., drug, device and/or biologic components) that would ordinarily require review by different FDA centers if authorized as standalone products, and this coordination may result in additional delays due to regulatory timing constraints and uncertainties in the product development and approval process.

A combination product candidate with a biologic primary mode of action generally would be reviewed and approved pursuant to a BLA. However, the applicable approval pathway for a product candidate may be a BLA or an NDA, depending on FDA’s determination of, among other things, the product’s primary mode of action and constituent parts, and we cannot predict with certainty how FDA will classify any of our product candidates. In reviewing the BLA for such a product, however, FDA reviewers in the biologic center could consult with their counterparts in the drug or device centers to ensure that the drug and device component of the combination product candidate, as applicable, met all requirements applicable to its category. In addition, under FDA regulations, combination products are subject to the cGMP requirements applicable to each component within the combination. We believe our combination product candidates are likely to be reviewed by the FDA under a BLA.

U.S. Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of FDA approval of our current product candidates and any future product candidates, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (commonly referred to as the "Hatch Waxman Amendments"). The Hatch Waxman Amendments permit restoration of the patent term of up to five years as compensation for patent term lost during product development and FDA regulatory review process. Patent term restoration, however, cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one half the time between the effective date of an IND and the submission date of a BLA plus the time between the submission date of a

19

BLA and the approval of that application, except that the review period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office ("PTO"), in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we may apply for restoration of patent term for our currently owned or licensed patents to add patent life beyond its current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant BLA.

An abbreviated approval pathway for biological products shown to be biosimilar to, or interchangeable with, an FDA licensed reference biological product was created by the Biologics Price Competition and Innovation Act of 2009. This amendment to the PHSA, in part, attempts to minimize duplicative testing. Biosimilarity, which requires that the biological product be highly similar to the reference product notwithstanding minor differences in clinically inactive components and that there be no clinically meaningful differences between the product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies and a clinical trial or trials. Interchangeability requires that a biological product be biosimilar to the reference product and that the product can be expected to produce the same clinical results as the reference product in any given patient and, for products administered multiple times to an individual, that the product and the reference product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological product without such alternation or switch.

A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the U.S. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a biological product if the licensure is for a supplement for the biological product or for a subsequent application by the same sponsor or manufacturer of the biological product (or licensor, predecessor in interest, or other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device or strength, or for a modification to the structure of the biological product that does not result in a change in safety, purity, or potency.

Pediatric exclusivity is another type of regulatory market exclusivity in the U.S. Pediatric exclusivity, if granted, adds six months to existing regulatory exclusivity periods for all formulations, dosage forms, and indications of the biologic. This six-month exclusivity may be granted based on the voluntary completion of a pediatric trial in accordance with an FDA issued “Written Request” for such a trial.

Federal and State Fraud and Abuse, Data Privacy and Security Laws and Regulations

In addition to FDA restrictions on marketing of pharmaceutical products, federal and state fraud and abuse laws restrict business practices in the pharmaceutical industry. These laws include anti-kickback and false claims laws and regulations as well as data privacy and security laws and regulations.

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce or in return for purchasing, leasing, ordering, or arranging for or recommending the purchase, lease, or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exemptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases, or recommendations may be subject to scrutiny if they do not meet the requirements of a statutory or regulatory exception or safe harbor. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

The federal False Claims Act prohibits any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, using, or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. government. A violation of the federal Anti-Kickback Statute may also constitute a false or fraudulent claim for purposes of the civil False Claims Act.

20

Several pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved, and thus non-covered, uses. In addition, many states have similar fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.

The federal False Claims Act also created federal criminal statutes that prohibit knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third party payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Pharmaceutical companies are also subject to the civil monetary penalties statute, which imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and other health care providers. The Patient Protection and Affordable Care Act, as amended by the ACA, signed into law on March 2010, created new federal requirements for reporting, by applicable manufacturers of covered drugs, payments and other transfers of value to physicians and teaching hospitals. Applicable manufacturers are also required to report annually to the government certain ownership and investment interests held by physicians and their immediate family members. In addition, certain states require implementation of commercial compliance programs and compliance with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, impose restrictions on marketing practices, and/or tracking and reporting of gifts, compensation and other remuneration or items of value provided to physicians and other health care professionals and entities.

We may also be subject to data privacy and security obligations, including federal and state laws related to the privacy and security of personal information. The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and its implementing regulations (the “HIPAA Rules”) imposes specified requirements relating to the privacy, security and transmission of protected health information (“PHI”) and may apply to certain of the information we process. Among other things, HITECH makes HIPAA’s security and certain of its privacy requirements directly applicable to “business associates,” defined as independent contractors or agents of covered entities, or other business associates, that create, receive, maintain, obtain, or transmit PHI in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same requirements, thus complicating compliance efforts.

To the extent that any of our product candidates, once approved, are sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or other transfers of value to healthcare professionals.

The shifting commercial compliance environment and the need to build and maintain robust systems to comply with different compliance and/or reporting requirements in multiple jurisdictions increase the possibility that a healthcare company may violate one or more of the requirements. If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs and imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

21

Coverage and reimbursement

Successful sales of our product candidates in the U.S. market, if approved, will depend, in part, on the extent to which our drugs will be eligible for adequate reimbursement by third-party payors, such as government health programs, such as Medicare and Medicaid, and private health insurance (including managed care plans). Patients generally rely on such third-party payors to reimburse all or part of the costs associated with their prescriptions and therefore adequate coverage and reimbursement from such third-party payors are critical to new and ongoing product acceptance. Coverage and reimbursement policies for drug products can differ significantly from payor to payor as there is no uniform policy of coverage and reimbursement for drug products among third-party payors in the United States. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a return on our investment. There may be significant delays in obtaining coverage and reimbursement as the process of determining coverage and reimbursement is often time consuming and costly. Further, third-party payors are increasingly reducing reimbursements for medical drugs and services and implementing measures to control utilization of drugs such as requiring prior authorization or step therapy for coverage, among other things. For products administered under the supervision of a physician or other healthcare professional, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used or delivered may not be available, which may impact physician utilization.

Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic drugs. Adoption or expansion of price controls and cost-containment measures could further limit our net revenue and results. Decreases in third-party payor reimbursement for our product candidates, if approved, or a decision by a third-party payor to not cover our product candidates could have a material adverse effect on our sales, results of operations and financial condition.

General regulatory cost control measures may also affect reimbursement for our products. If we obtain approval to market a product candidate in the United States, we may be subject to spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs and/or any significant taxes or fees.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the Centers for Medicare and Medicaid Services ("CMS"), an agency within the Department of Health and Human Services ("HHS"), determines whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree.

Factors payors consider in determining reimbursement are based on whether the product is:

•a covered benefit under its health plan;

•safe, effective and medically necessary;

•appropriate for the specific patient;

•cost-effective; and

•neither experimental nor investigational.

Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of reimbursement. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs.

Healthcare reform

The U.S. government, state legislatures, and foreign governments have shown significant interest in implementing cost containment programs to limit the growth healthcare costs, including price-controls, restrictions on reimbursement, and requirements for substitution of generic products for branded prescription drugs.

22

For example, in March 2010, the Affordable Care Act, or ACA, was enacted in the United States and substantially changed the way healthcare is financed by both the government and private insurers. The ACA contains provisions that may reduce the profitability of drug products. Among other things, the ACA established an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents; extended manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; expanded eligibility criteria for Medicaid programs; expanded the entities eligible for discounts under the 340B drug pricing program; and increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program. Since its enactment, there have been executive, judicial and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Thus, the ACA will remain in effect in its current form.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminated the statutory Medicaid drug rebate cap, for single source and innovator multiple source drugs, beginning January 1, 2024. The rebate was previously capped at 100% of a drug’s average manufacturer price. Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries, presidential executive orders and proposed and enacted federal and state legislation and regulations designed to, among other things, reduce the cost of prescription drugs under Medicare, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products.

Most recently, on August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 ("IRA"), into law. Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations with Medicare (beginning in 2026), with prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program (effective January 1, 2025). The IRA permits the Secretary of the Department of Health and Human Services, or HHS, to implement many of these provisions through guidance, as opposed to regulation, for the initial years.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs.

Existing healthcare reform measures, as well as the implementation of additional cost containment measures or other reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates, if approved.

Foreign Regulation

In order to market any product outside of the United States, we must comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy and governing, among other things, clinical trials and commercial sales and distribution of our products. While our management and many of our consultants are familiar with and have been responsible for gaining marketing approval in many countries, we have not reviewed the specific regulations in countries outside of the United States.

Employees & Human Capital Resources

As of March 9, 2026, we have a total of 12 full-time employees, four of whom hold a Ph.D or MD degree. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We consider our relationships with our employees to be good. In addition, we rely on a number of consultants to assist us.

We strive to foster collaborative, communicative and flexible environment so that our employees feel supported in the workplace. Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and new employees. The principal purposes of our benefits and incentive plans are to attract, retain and motivate our employees, consultants and directors through the granting of stock-based compensation awards, providing competitive benefits packages and providing cash-based performance bonuses, in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives.

We anticipate that we will need to hire additional employees or independent contractors for our continued development efforts. We also intend to utilize independent contractors and outsourced services, such as contract research organizations ("CROs") and third party manufacturers, where possible and appropriate.
