Biomea Fusion (BMEA) Risk Analysis

We may not be able to initiate or continue our ongoing and planned clinical trials on a timely basis or at all for our product candidates if we are unable to recruit and enroll a sufficient number of eligible patients to participate in these trials through completion of such trials as required by the FDA or other comparable foreign regulatory authorities. Patient enrollment is a significant factor in the timing of clinical trials. Our ability to enroll eligible patients may be limited or may result in slower enrollment than we anticipate. Our clinical trials will compete with other clinical trials that are in the same therapeutic areas as our product candidates, and this competition reduces the number and types of patients available to us, as some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Because the number of qualified clinical investigators and clinical trial sites is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. In addition, there may be limited patient pools from which to draw for clinical studies. In addition to the rarity of some diseases, particularly certain cancer indications, the eligibility criteria of our clinical trials will further limit the pool of available study participants as we will require that patients have specific characteristics that we can measure or to assure their disease is either severe enough or not too advanced to include them in a study. Patient enrollment for our ongoing and planned clinical trials may be affected by other factors, including: - size and nature of the patient population;- severity of the disease under investigation;- availability and efficacy of approved drugs or other methods of treatment for the disease under investigation;- patient eligibility criteria for the trial in question as defined in the protocol;- perceived risks and benefits of the product candidate under study;- clinicians' and patients' perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new products that may be approved or future product candidates being investigated for the indications we are pursuing;- clinicians' willingness to screen their patients for biomarkers to indicate which patients may be eligible for enrollment in our clinical trials;- delays in or temporary suspension of the enrollment of patients in our planned clinical trials due to a continued and prolonged public health emergency such as the COVID-19 pandemic;- ability to obtain and maintain patient consents;- patient referral practices of physicians;- the ability to monitor patients adequately during and after treatment;- proximity and availability of clinical trial sites for prospective patients; and - the risk that patients enrolled in clinical trials will drop out of the trials before completion, including as a result of contracting health conditions, or, because they may be late-stage cancer patients, will not survive the full terms of the clinical trials. These factors may make it difficult for us to enroll enough patients to complete our clinical trials in a timely and cost-effective manner. Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates and jeopardize our ability to obtain marketing approval for the sale of our product candidates. Furthermore, even if we are able to enroll a sufficient number of patients for our clinical trials, we may have difficulty maintaining participation in our clinical trials through the treatment and any follow-up periods.

If our product candidates are associated with undesirable side effects or have unexpected characteristics in preclinical studies or clinical trials when used alone or in combination with other approved products or investigational new drugs we may need to interrupt, delay or abandon their development or limit development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may prevent us from achieving or maintaining market acceptance of the affected product candidate and may adversely affect our business, financial condition and prospects significantly. As is the case with many oncology drugs, it is likely that there may be significant side effects associated with their use. BMF-219, BMF-500 or future product candidates may be used in populations for which safety concerns may be reviewed by regulatory agencies. For example, if the administration of BMF-219 leads to levels of menin inhibition that far exceed those achieved by well-studied non-covalent menin inhibitors, it is possible that patients' responses could be both unexpected and negative. In addition, we or our future collaborators may study BMF-219 in combination with other therapies, which may exacerbate adverse events associated with the therapy. Further, our product candidates will be used in patients that have weakened immune systems, which may exacerbate any potential side effects associated with their use. Patients treated with BMF-219, BMF-500 or any of our future product candidates may also be undergoing surgical, radiation and chemotherapy treatments, which can cause side effects or adverse events that are unrelated to our product candidate but may still impact the success of our clinical trials. The inclusion of critically ill patients in our clinical trials may result in deaths or other adverse medical events due to other therapies or medications that such patients may be using or due to the gravity of such patients' illnesses. For example, it is expected that some of the patients enrolled in our clinical trials of BMF-219 will die or experience major clinical events either during the course of our clinical trials or after participating in such trials. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. If further significant adverse events or other side effects are observed in any of our current or future clinical trials, we may have difficulty recruiting patients to the clinical trials, patients may drop out of our trials, or we may be required to abandon the trials or our development efforts of that product candidate altogether. We, the FDA, other comparable regulatory authorities or an IRB may suspend clinical trials of a product candidate at any time for various reasons, including a belief that subjects in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics developed in the biotechnology industry that initially showed therapeutic promise in early-stage trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance due to its tolerability versus other therapies. Any of these developments could materially adversely affect our business, financial condition and prospects. Further, if any of our product candidates obtains marketing approval, toxicities associated with such product candidates previously not seen during clinical testing may also develop after such approval and lead to a number of potentially significant negative consequences, including, but not limited to: - regulatory authorities may suspend, limit or withdraw approvals of such product, or seek an injunction against its manufacture or distribution;- regulatory authorities may require additional warnings on the label, including "boxed" warnings, or issue safety alerts, Dear Healthcare Provider letters, press releases or other communications containing warnings or other safety information about the product;- we may be required to change the way the product is administered or conduct additional clinical trials or post-approval studies;- we may be required to create a risk evaluation and mitigation strategy (REMS), which could include a medication guide outlining the risks of such side effects for distribution to patients;- we may be subject to fines, injunctions or the imposition of criminal penalties;- we could be sued and held liable for harm caused to patients; and - our reputation may suffer. Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could seriously harm our business.

From time to time, we have announced or published, and may continue to publicly disclose, preliminary or top-line data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the top-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, top-line data should be viewed with caution until the final data are available. From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. Adverse differences between preliminary or interim data and final data could materially adversely affect our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our common stock. Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be adversely affected, which could materially adversely affect our business, financial condition and results of operations.

The discovery and development of covalent small molecule therapies for patients with genetically-defined cancers and metabolic diseases, with a particular focus on menin, is an emerging field. While there is scientific evidence to support the feasibility of developing covalent therapies, the significant complexity and potential safety and toxicity concerns associated with poorly designed covalent binders have historically discouraged drug developers from pursuing this drug class. In particular, a significant risk for toxicity is posed by these small-molecule covalent binders if they demonstrate a more promiscuous binding profile than intended, which can potentially cause unacceptable levels of off-target interactions. While we believe the significant expertise, foundational knowledge and capabilities that our management team members have accumulated over their extensive careers and that we have expanded and refined since our inception positions us to overcome such challenges, there can be no assurance that we will be successful. Even if we are able to limit off-target interaction, there can be no assurance that treatment with any of our novel covalent small molecule product candidates will demonstrate the deep inactivation of their targets or offer greater therapeutic windows than conventional non-covalent drugs. It is possible that the targets we select, such as menin, could be effectively and safely treated by more frequent dosing of non-covalent drugs, which could limit the potential advantages or perceived benefits of our covalent inhibitor product candidates. Furthermore, although we believe, based on our preclinical work and research on covalent binders generally, that highly selective covalent inhibitors of certain critically important oncogenic drivers, such as menin, known to impact cellular processes have potential as precision oncology targets, clinical results may not confirm this hypothesis or may only confirm it for certain inhibitors or certain tumor types. In addition, our lead product candidate, BMF-219, is in clinical development, and we dosed the first patient with our second product candidate, BMF-500, in October 2023, following clearance of our IND by the FDA in May 2023. Our current data is primarily limited to clinical data in a relatively small patient population for BMF-219, as well as animal models and preclinical cell lines for BMF-219 and BMF-500. These results may not be replicated in larger clinical trials, or, in the case of preclinical data, translate into humans. As such, even if we are able to develop small-molecule therapy candidates that demonstrate positive results in preclinical studies or early-stage clinical trials, there can be no assurance that such product candidates will subsequently demonstrate significant clinical benefit in vivo or in larger trials or will be well-tolerated. Further, even if our approach is successful in demonstrating the clinical benefit of using our lead product candidate, BMF-219, which is designed to be a highly active and selective covalent inhibitor of menin, in certain menin-driven cancers and/or metabolic diseases, we may never successfully identify additional covalent binding product candidates to validated oncology or other targets through our FUSIONTM System. Therefore, we do not know if our approach of treating patients with genetically-defined cancers and metabolic diseases will be successful, and if our approach is unsuccessful, our business will be materially adversely affected.

A key element of our strategy is to utilize our FUSIONTM System to build a pipeline of novel covalent small molecule product candidates and progress these product candidates through clinical development for the treatment of various cancers and metabolic diseases. Although our research and development efforts to date have resulted in our discovery and preclinical development of BMF-219, BMF-500 and other programs, BMF-219, BMF-500 and such other programs may not be safe or effective in our target indications, and we may not be able to further develop BMF-219, BMF-500 or any future product candidates. Our FUSIONTM System is unproven and may not enable us to build a pipeline of product candidates. For example, we may not be successful in identifying validated and novel targets that are amenable to direct intervention with a covalent binder, we may not succeed in creating novel chemical scaffolds to exploit target proteins and we may not be able to maximize the selectivity, potency and safety of our covalent small molecules. There can be no assurance that any development problems we experience in the future related to our platform will not cause significant delays or unanticipated costs or that such development problems can be solved. Even if we are successful in building our pipeline of product candidates, the potential product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable toxicity or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. Furthermore, if one or more of our covalent small molecule product candidates generally proves to be ineffective, unsafe or commercially unviable, the development of our entire platform and pipeline utilizing our FUSIONTM System could be delayed, potentially permanently. Even if our product candidates are successful in inhibiting certain protein binding, such success would not provide a guarantee of the effectiveness of such product candidate in total tumor regression in vivo. For example, even if BMF-219 demonstrates an ability to inhibit menin in vivo, there can be no assurance that such inhibition will provide significant clinical benefit when evaluated in humans. In addition, development of covalent small molecules is highly complex and we may experience delays in developing a sustainable, reproducible and scalable manufacturing process or transferring that process to manufacturing partners, which may prevent us from initiating or completing our planned clinical trials or commercializing any products we develop on a timely or profitable basis, if at all. In addition, since we have not yet entered clinical development, we do not know the specific doses that may be effective in the clinic or, if approved, commercially. Finding a suitable dose may delay our anticipated clinical development timelines. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue which could materially adversely affect our business, financial condition and results of operations.

We are early in our development efforts. We have not yet successfully completed clinical testing of our lead product candidate, BMF-219, in human subjects for various types of solid tumors or liquid tumors or type 2 diabetes mellitus, or our second product candidate, BMF-500, in human subjects for relapsed or refractory acute leukemia with FLT3 wild-type and FLT3 mutations, including those with MLLr/NPM1 mutations. We have only recently received IND clearance to pursue the clinical development of BMF-219 in human subjects with type 1 diabetes mellitus. Our ability to generate product revenue, which we do not expect will occur for many years, if ever, will depend heavily on the successful clinical development and eventual commercialization of BMF-219, BMF-500, and one or more of our future product candidates. The success of our product candidates will depend on several factors, including the following: - our ability to continue our business operations and product candidate research and development, and adapt to any changes in the regulatory approval process, manufacturing supply or clinical trial requirements and timing due to a continued and prolonged public health emergencies such as the COVID-19 pandemic;- successful completion of preclinical studies;- receipt of authorization to proceed under INDs for our planned clinical trials or future clinical trials;- successful initiation, patient enrollment in, and completion of clinical trials, including our ongoing Phase 1 clinical trial of BMF-219 in various types of liquid tumors, our Phase 1/1b clinical trial of BMF-219 in various types of solid tumors, our Phase 1/2 clinical trial of BMF-219 in type 2 diabetes mellitus, our Phase 2 clinical trial of BMF-219 in type 1 diabetes mellitus, and our Phase 1 clinical trial of BMF-500 in relapsed or refractory acute leukemia with FLT3 wild-type and FLT3 mutations, including those with MLL1r / NPM1 mutations;- whether BMF-219, BMF-500 or any other product candidates that we may identify and pursue will demonstrate safety, tolerability and efficacy profiles that are satisfactory to the FDA or any foreign regulatory authority for marketing approval;- receipt of marketing approvals for our product candidates from applicable regulatory authorities;- completion of any required post-marketing approval commitments to applicable regulatory authorities in order to maintain marketing authorization for any of our product candidates that receive regulatory approval;- obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;- making arrangements with third-party manufacturers, or establishing manufacturing capabilities, for both clinical and commercial supplies of our product candidates, if any product candidates are approved;- establishing sales, marketing, and distribution capabilities and launching commercial sales of our products, if and when approved, whether alone or in collaboration with others;- acceptance of our products, if and when approved, by patients, the medical community and third-party payors;- effectively competing with other therapies for cancer or metabolic diseases;- obtaining and maintaining third-party coverage and adequate reimbursement; and - maintaining a continued acceptable safety profile of our products following approval. Many of these factors are beyond our control, and it is possible that we may never obtain regulatory approval for our product candidates even if we expend substantial time and resources seeking their development and approval. If we do not achieve regulatory approval in a timely manner or at all, we could experience significant delays or an inability to commercialize our current or future product candidates, which would materially adversely affect our business. If we do not receive regulatory approvals for our current or future product candidates, we will not be able to continue our operations. The success of our business, including our ability to finance our company and generate revenue from products in the future, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of the product candidates we develop, which may never occur. Our current product candidates, and any future product candidates we develop, will require additional preclinical and clinical development, management of clinical, preclinical and manufacturing activities, marketing approval in the United States and other markets, demonstrating cost-effectiveness to pricing and reimbursement authorities, obtaining sufficient manufacturing supply for both clinical development and commercial production in accordance with cGMP, building of a commercial organization, and substantial investment and significant marketing efforts before we generate any revenue from product sales, if ever. We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process or transferring that process to commercial partners, which may prevent us from completing our preclinical studies or clinical trials or commercializing our product candidates on a timely or profitable basis, if at all. Changes in the manufacturing process or facilities will require further comparability analysis and approval by FDA before implementation, which could delay our preclinical studies, clinical trials and product candidate development, and could require additional preclinical studies and clinical trials, including bridging studies, to demonstrate consistent and continued safety and efficacy. We have not previously submitted an NDA to the FDA or similar approval filings to a comparable foreign regulatory authority, for any product candidate. An NDA or other relevant regulatory filing must include extensive preclinical and clinical data and supporting information to establish that the product candidate is safe and effective for each desired indication. The NDA or other relevant regulatory filing must also include significant information regarding the chemistry,manufacturing and controls for the product. We cannot be certain that our current or future product candidates will be successful in clinical trials or receive regulatory approval. Further, even if they are successful in clinical trials, our product candidates or any future product candidates may not receive regulatory approval. If we do not receive regulatory approvals for current or future product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approval to market a product candidate, our revenue will depend, in part, upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights for each product candidate, as well as the availability of competitive products, whether there is sufficient third-party reimbursement and adoption by physicians.

In order to obtain FDA approval to market a new small molecule product, we must demonstrate the safety and efficacy of our product candidates in humans to meet the FDA requirements. To meet these requirements, we will have to conduct adequate and well-controlled clinical trials. Clinical testing is expensive, time-consuming, and subject to uncertainty. Before we can commence clinical trials for a product candidate, we must complete extensive preclinical studies that support our planned and future INDs in the United States. At present, we have two product candidates, BMF-219 and BMF-500, under investigation in clinical trials, with the first patient recently dosed with BMF-500. We cannot be certain of the timely completion or outcome of our preclinical studies and clinical trials and cannot predict if the FDA will allow our existing and proposed clinical programs to proceed or if the outcomes of our preclinical studies and clinical trials will ultimately support further development of our programs. Our lead product candidate, BMF-219, is in clinical development in selected liquid tumors, solid tumors, and type 1 and type 2 diabetes mellitus, and we cannot be sure that we will be able to submit INDs or similar applications with respect to additional indications or other product candidates on the timelines we expect, if at all, and we cannot be sure that submission of IND or similar applications will result in the FDA or other regulatory authorities allowing clinical trials to begin. Conducting preclinical testing and clinical trials represents a lengthy, time-consuming and expensive process. The length of time may vary substantially according to the type, complexity and novelty of the program, and often can be several years or more per program. Delays associated with programs for which we are directly conducting preclinical studies may cause us to incur additional operating expenses. The commencement and rate of completion of preclinical studies and clinical trials for a product candidate may be delayed by many factors, including, for example: - inability to generate sufficient preclinical or other in vivo or in vitro data to support the initiation of clinical trials;- timely completion of preclinical laboratory tests, animal studies and formulation studies in accordance with the FDA's GLP requirements and other applicable regulations;- approval by an independent IRB ethics committee at each clinical site before each trial may be initiated;- delays in reaching a consensus with regulatory agencies on study design and obtaining regulatory authorization to commence clinical trials;- delays in reaching agreement on acceptable terms with prospective CROs, and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;- delays in identifying, recruiting and training suitable clinical investigators;- delays in recruiting suitable patients to participate in our clinical trials;- delays in manufacturing, testing, releasing, validating or importing/exporting sufficient stable quantities of our product candidates for use in clinical trials or the inability to do any of the foregoing;- insufficient or inadequate supply or quality of product candidates or other materials necessary for use in clinical trials, or delays in sufficiently developing, characterizing or controlling a manufacturing process suitable for clinical trials;- imposition of a temporary or permanent clinical hold by regulatory authorities;- developments on trials conducted by competitors for related technology that raises FDA or foreign regulatory authority concerns about risk to patients of the technology broadly, or if the FDA or a foreign regulatory authority finds that the investigational protocol or plan is clearly deficient to meet its stated objectives;- delays in recruiting, screening and enrolling patients and delays caused by patients withdrawing from clinical trials or failing to return for post-treatment follow-up;- difficulty collaborating with patient groups and investigators;- failure by our CROs, other third parties or us to adhere to clinical trial protocols;- failure to perform in accordance with the FDA's or any other regulatory authority's GCPs, or applicable regulatory guidelines in other countries;- occurrence of adverse events associated with the product candidate that are viewed to outweigh its potential benefits, or occurrence of adverse events in trial of the same class of agents conducted by other companies;- changes to the clinical trial protocols;- clinical sites deviating from trial protocol or dropping out of a trial;- changes in regulatory requirements and guidance that require amending or submitting new clinical protocols;- changes in the standard of care on which a clinical development plan was based, which may require new or additional trials;- selection of clinical endpoints that require prolonged periods of observation or analyses of resulting data;- the cost of clinical trials of our product candidates being greater than we anticipate;- clinical trials of our product candidates producing negative or inconclusive results, which may result in our deciding, or regulators requiring us, to conduct additional clinical trials or abandon development of such product candidates;- transfer of manufacturing processes to larger-scale facilities operated by a contract manufacturing organization (CMO), and delays or failure by our CMOs or us to make any necessary changes to such manufacturing process; and - third parties being unwilling or unable to satisfy their contractual obligations to us. In addition, disruptions caused by continued and prolonged public health emergencies such as the COVID-19 pandemic, may increase the likelihood that we encounter such difficulties or delays in initiating, enrolling, conducting or completing our planned and ongoing preclinical studies and clinical trials. Any inability to successfully initiate or complete preclinical studies or clinical trials could result in additional costs to us or impair our ability to generate revenue from product sales. In addition, if we make manufacturing or formulation changes to our product candidates, we may be required to or we may elect to conduct additional studies to bridge our modified product candidates to earlier versions. Clinical trial delays could also shorten any periods during which our products, if and when approved, have patent protection and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product candidates and may seriously harm our business. Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable foreign regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates. Delays in the completion of any preclinical studies or clinical trials of our product candidates will increase our costs, slow down our product candidate development and approval process and delay or potentially jeopardize our ability to commence product sales and generate product revenue. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. Any delays to our preclinical studies or clinical trials that occur as a result could shorten any period during which we may have the exclusive right to commercialize our product candidates and our competitors may be able to bring products to market before we do, and the commercial viability of our product candidates could be significantly reduced. Any of these occurrences may harm our business, financial condition and prospects significantly.

We will be required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are safe and effective before we can seek regulatory and marketing approvals for their commercial sale. Success in preclinical studies does not mean that future clinical trials will be successful. For instance, we do not know whether BMF-219 or BMF-500 will perform in clinical trials as BMF-219 or BMF-500 have performed in preclinical studies, nor can we predict how our future product candidates will perform in future preclinical studies or clinical trials. Product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA and other comparable foreign regulatory authorities despite having progressed through preclinical studies and early-stage clinical trials. Regulatory authorities may also limit the scope of later-stage trials until we have demonstrated satisfactory safety, which could delay regulatory approval, limit the size of the patient population to which we may market our product candidates or prevent regulatory approval. In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, differences in and adherence to the dose and dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. Patients treated with our product candidates may also be undergoing surgical, radiation and chemotherapy treatments and may be using other approved products or investigational new drugs, which can cause side effects or adverse events that are unrelated to our product candidates. As a result, assessments of efficacy can vary widely for a particular patient, and from patient to patient and site to site within a clinical trial. This subjectivity can increase the uncertainty of, and adversely impact, our clinical trial outcomes.

We are currently focused on the discovery and development of novel covalent small molecules to treat patients with genetically defined cancers and metabolic diseases. We seek to maintain a process of prioritization and resource allocation among our programs to maintain a balance between advancing our lead product candidate, BMF-219, as well as developing BMF-500 and any future product candidates. Our decisions concerning the allocation of research, development, collaboration, management, and financial resources toward particular product candidates or therapeutic areas may not lead to the development of any viable commercial product and may divert resources away from better opportunities with other therapeutic platforms or product candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through future collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights. In addition, if we make incorrect determinations regarding the viability or market potential of any of our programs or product candidates or misread trends in the cancer or metabolic disease treatment landscape or in the pharmaceutical, biopharmaceutical or biotechnology industry more generally, our business, financial condition and results of operations could be materially adversely affected.

We have never commercialized a product candidate and we currently have no sales force, marketing or distribution capabilities. To achieve commercial success for the product candidates which we may license to others, we will rely on the assistance and guidance of those collaborators. For product candidates for which we retain commercialization rights and marketing approval, we will have to develop our own sales, marketing and supply organization or outsource these activities to a third party. Factors that may affect our ability to commercialize our product candidates, if approved, on our own include recruiting and retaining adequate numbers of effective sales and marketing personnel, developing adequate educational and marketing programs to increase public acceptance of our product candidates, ensuring regulatory compliance of our company, employees and third parties under applicable healthcare laws and other unforeseen costs associated with creating an independent sales and marketing organization. Developing a sales and marketing organization will be expensive and time-consuming and could delay the launch of our product candidates upon approval. We may not be able to build an effective sales and marketing organization. If we are unable to build our own distribution and marketing capabilities or to find suitable partners for the commercialization of our product candidates, we may not generate revenue from them or be able to reach or sustain profitability.

If the FDA determines that a product candidate offers a treatment for a serious condition and, if approved, the product would provide a significant improvement in safety or effectiveness, the FDA may designate the product candidate for priority review. A priority review designation means that the goal for the FDA to review an application is six months, rather than the standard review period of ten months. We may request priority review for our product candidates. The FDA has broad discretion with respect to whether or not to grant priority review status to a product candidate, so even if we believe a particular product candidate is eligible for such designation or status, the FDA may decide not to grant it. Moreover, a priority review designation does not necessarily result in an expedited regulatory review or approval process or necessarily confer any advantage with respect to approval compared to conventional FDA procedures. Receiving priority review from the FDA does not guarantee approval within the six-month review cycle or at all.

As part of our business strategy, we may seek orphan drug designation (ODD) for any eligible product candidates we develop, and we may be unsuccessful. Regulatory authorities in some jurisdictions, including the United States, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population of 200,000 or more in the United States where there is no reasonable expectation that the cost of developing and making available the drug will be recovered from sales in the United States. Our target indications may include diseases with large patient populations or may include orphan indications. However, there can be no assurances that we will be able to obtain orphan designations for our product candidates. In the United States, ODD entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. In addition, if a product that has ODD subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity. Orphan drug exclusivity in the United States provides that the FDA may not approve any other applications, including a full NDA, to market the same drug for the same indication for seven years, except in circumstances such as a showing of clinical superiority to the product with orphan product exclusivity in instances of supply issues. Even if we obtain ODD for a product candidate, we may not be able to obtain or maintain orphan drug exclusivity for that product candidate. We may not be the first to obtain marketing approval of any product candidate for which we have obtained ODD for the orphan-designated indication due to the uncertainties associated with developing pharmaceutical products. In addition, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to ensure that we will be able to manufacture sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs may be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug with the same active moiety for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care or the manufacturer of the product with orphan exclusivity is unable to maintain sufficient product quantity. Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the product candidate any advantage in the regulatory review or approval process.
