Brainstorm Cell Therapeutics (GHD) Risk Analysis

Our intended cell therapeutic treatment NurOwn for ALS involves a new approach using stem cells to treat ALS. Cell therapy is still a developing area of research, with few cell therapy products approved for clinical use. Many of the existing cellular therapy candidates are based on novel cell technologies that are inherently risky and may not be understood or accepted by the marketplace. The novel nature of our cell therapy technology creates significant challenges with respect to product development and optimization, manufacturing, government regulation and approval, third-party reimbursement.

Despite our prior experience in conducting and managing clinical trials, we may not be able to conduct and manage future trials successfully. We have limited experience in the application process to obtain regulatory approvals. If our clinical trials are unsuccessful, or if we do not complete our clinical trials, we may not receive regulatory approval for or be able to commercialize our stem cell therapies. If we do not succeed in conducting and managing our preclinical development activities or clinical trials, or in obtaining regulatory approvals, we might not be able to commercialize our stem cell therapies, or might be significantly delayed in doing so, which will materially harm our business. Our ability to generate revenues from any of our stem cell therapies will depend on a number of factors, including our ability to successfully complete clinical trials, obtain necessary regulatory approvals and implement our commercialization strategy. We may, and anticipate that we will need to, transition from a company with a research and development focus to a company capable of supporting commercial activities and we may not succeed in such a transition.

We are subject to the risks of failure inherent in the development of products based on new technologies. The novel nature of our autologous stem cell therapy creates significant challenges with regard to product development and optimization, manufacturing, government regulations, and market acceptance. For example, although cell therapy has been available in oncology, the FDA's experience with mesenchymal stem cell therapies is limited. None have been approved by the FDA for commercial sale in the US, and the pathway to regulatory approval for our stem cell therapies may accordingly be more complex and lengthy. As a result, the development and commercialization pathway for our therapies may be subject to increased uncertainty, as compared to the pathway for new conventional drugs. If serious or unexpected adverse side effects are identified during the development of our NurOwn stem cell therapy, we may need to abandon or limit its development. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Undesirable side effects caused by NurOwn could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. If patients treated with our NurOwn stem cell therapy suffer serious or unexpected adverse effects, we may need to abandon its development or limit development to certain uses or subpopulations in which these effects are less prevalent, less severe or more acceptable from a risk-benefit perspective. Any of these occurrences may harm our business, financial condition and prospects significantly.

The therapeutic treatment development and regulatory approval process is expensive, uncertain and time-consuming. As part of the regulatory process, we conduct clinical trials, for our NurOwn stem cell therapy to demonstrate safety and efficacy in humans to meet the requirements of the FDA and regulatory authorities in other countries. We have completed our Phase 3 ALS trial and announced on February 2021 that the FDA concluded from their initial review that the current level of clinical data does not provide the threshold of substantial evidence that FDA is seeking to support a BLA. On November 10, 2022, we announced that we had received a RTF letter from the FDA regarding our BLA. The FDA indicated that we could request a Type A meeting to discuss the content of the RTF letter, and the Type A meeting was held on January 11, 2023. We notified the FDA on February 6, 2023 of our decision to request the FDA to file the NurOwn BLA for ALS over Protest. We submitted an amendment to our BLA on March 7, 2023, in which we responded to the majority of the items included in the RTF letter. Written notification was received on March 22, 2023 from the FDA project manager associated with the BLA confirming the FDA's decision to grant an ADCOM for the NurOwn BLA for ALS. On September 27, 2023, we announced that the Advisory Committee voted, with 17 voting no, one voting yes, and one abstention, that NurOwn did not demonstrate substantial evidence of effectiveness for treatment of mild to moderate ALS. On October 18, 2023, we announced that the FDA invited the Company to request an expedited face-to-face meeting to discuss the path forward for NurOwn as a treatment for ALS. BrainStorm remains committed to the ALS Community and is actively exploring the next steps in support of NurOwn, including publication of emerging clinical data and development of a protocol for an additional clinical study. On October 18, 2023 Brainstorm announced that the BLA for NurOwn would be withdrawn. The BLA was withdrawn on November 3, 2023. The decision to withdraw the BLA was coordinated with the FDA and is viewed by the FDA as a withdrawal without prejudice. On November 20, 2023, we announced that the FDA granted the company a meeting to discuss the regulatory path forward for NurOwn in ALS. The meeting took place on December 6, 2023. On December 7, 2023, we announced the completion of a productive meeting with the FDA to discuss NurOwn. The primary objective of the meeting was to discuss plans for a SPA with the FDA on the overall protocol design for a planned Phase 3b registrational trial for NurOwn. As an outcome of the meeting, BrainStorm will submit relevant documentation as outlined by the FDA to support the SPA. The ultimate goal of the SPA is to secure the FDA's agreement that critical elements of the overall protocol design (e.g., entry criteria, endpoints, planned analyses) are adequate and acceptable for a study intended to support a future marketing application. On February 23, 2024, we announced that we submitted the SPA request to the FDA for the planned Phase 3b clinical trial of NurOwn for the treatment of ALS. If we fail to obtain regulatory approval for our NurOwn stem cell therapy, we will be unable to market and sell it and we may never be profitable. A failure of one or more of our clinical trials can occur at any stage of testing. Results of later stage clinical trials may fail to show the desired safety and efficacy despite acceptable results in earlier clinical trials. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that have believed their product candidates performed satisfactorily in preclinical and clinical trials have nonetheless failed to obtain marketing approval of their treatments. Specifically, we are currently comparing NurOwn stem cell therapy against placebo. Comparisons of outcomes of other reported clinical trials may provide some insight into the efficacy of NurOwn stem cell therapy, however, these studies may be of limited comparative value due to the many factors that affect the outcome of clinical trials, some of which are not apparent in published reports. Additionally, several of our past, planned and ongoing clinical trials utilize an "open-label" trial design. An "open-label" clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved drug or placebo. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a "patient bias" where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an "investigator bias" where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge. The results from an open-label trial may not be predictive of future clinical trial results with any of our product candidates for which we include an open-label clinical trial when studied in a controlled environment with a placebo or active control.

We will need to acquire additional capabilities and effectively manage our operations and facilities to successfully pursue and complete future research, development and, if our NurOwn stem cell therapy receives regulatory approval, commercialization efforts. Currently, we have no experience in commercial-scale manufacturing, managing of large-scale information technology systems or managing a large-scale distribution system. We will need to add personnel and expand our capabilities, which may strain our existing managerial, operational, regulatory compliance, financial and other resources. To do this effectively, we must: - train, manage and motivate a growing employee base;- accurately forecast demand for our treatment; and - expand existing operational, financial and management information systems.

Regulatory approval of stem cell therapies that utilize novel technology such as ours can be more expensive and take longer than for other treatments that are based on more well-known or more extensively studied technology. This may lengthen the regulatory review process, require us to perform additional studies, including clinical trials, increase our development costs, lead to changes in regulatory positions and interpretations, delay or prevent approval and commercialization of these stem cell therapies or lead to significant post-approval limitations or restrictions. For example, the differentiated cell component of our NurOwn stem cell therapy is a complex biologic product that is manufactured from the patient's own bone marrow that must be appropriately harvested, isolated, expanded and differentiated so that its identity, strength, quality, purity and potency may be characterized prior to release for treatment. No differentiated cell treatment for ALS has yet been approved for marketing by the FDA or any other regulatory agency. The novel nature of our NurOwn stem cell therapy also means that fewer people are trained in or experienced with treatments of this type, which may make it difficult to recruit, hire and retain capable personnel for the research, development and manufacturing positions that will be required to continue our development and commercialization efforts.

Because we have limited financial and managerial resources, we have focused development of our NurOwn stem cell therapy for use in patients with ALS, PMS and AD. As a result, we may forego or delay pursuit of opportunities with other stem cell therapies or for other indications that later prove to have greater commercial potential. Our resource allocation decisions also may cause us to fail to capitalize on a viable commercial treatment, a more viable indication or profitable market opportunities. We have based our research and development efforts on our NurOwn stem cell therapy. Notwithstanding our large investment to date and anticipated future expenditures in our NurOwn stem cell therapy, we have not yet developed, and may never successfully develop, any marketed treatments using this approach. As a result of pursuing the development of our NurOwn stem cell therapy, we may fail to develop stem cell therapies or address indications based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success.

The pharmaceutical industry is characterized by rapidly changing markets, technology, emerging industry standards and frequent introduction of new products. The introduction of new products embodying new technologies, including new manufacturing processes, and the emergence of new industry standards may render our technologies obsolete, less competitive or less marketable. Advances in other treatment methods or in disease prevention techniques could significantly reduce or entirely eliminate the need for our stem cell services, planned products and therapeutic efforts. Additionally, technological or medical developments may materially alter the commercial viability of our technology or services, and require us to incur significant costs to replace or modify equipment in which we have a substantial investment. In either event, we may experience a material adverse effect on our business, results of operations and financial condition. To date, approved conventional therapies have not shown significant clinical benefit as disease modifying therapies in the indications that we are currently working on.

We have received royalty-bearing grants from the IIA, for research and development programs that meet specified criteria. The terms of the IIA's grants may limit various technology transfer know-how developed under an approved research and development program outside of Israel.

Regulatory authorities in some jurisdictions, including the United States and EU, may designate drugs or biologics for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is 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 the drug will be recovered from sales in the United States. In order to obtain Orphan Drug Designation, the request must be made before submitting a BLA. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. If a product that has Orphan Drug Designation subsequently receives the first FDA approval of that particular product for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, to market the biologic for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. As a result, even if one of our product candidates receives orphan exclusivity, the FDA can still approve other biologics for use in treating the same indication or disease or the same biologic for a different indication or disease during the exclusivity period. Furthermore, the FDA can waive orphan exclusivity if we are unable to manufacture sufficient supply of our product or orphan drug exclusivity can be overcome if a subsequent applicant demonstrates clinical superiority over our product. In the EU, the Committee for Orphan Medicinal Products of the EMA grants orphan designation to promote the development of products that are intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition, which either affects not more than five in 10,000 persons in the EU, or products intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and chronic condition when, without incentives, it is unlikely that the medicine would generate sufficient return to justify the necessary investment in its development. In each case, there must be no satisfactory method of diagnosis, prevention, or treatment which is authorized for marketing in the EU, or, if a method exists, the product would be of significant benefit to those affected by the condition. We have obtained from the FDA and EMA Orphan Drug Designations for NurOwn for the treatment of ALS. We may seek Orphan Drug Designation for other product candidates. Even if we obtain Orphan Drug Designation, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective, if we are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition, or if a subsequent applicant demonstrates clinical superiority over our products. In addition, although we may seek Orphan Drug Designation for other product candidates, we may never receive such designations. Any failure to obtain, maintain or otherwise recognize the benefits of orphan drug designation for our products or product candidates could have a material adverse effect on our prospects. On August 3, 2017, Congress passed the FDA Reauthorization Act of 2017 ("FDARA"). FDARA, among other things, codified the FDA's pre-existing regulatory interpretation to require that a sponsor demonstrate the clinical superiority of an orphan drug that is otherwise the same as a previously approved drug for the same rare disease in order to receive orphan drug exclusivity. The legislation reverses prior precedent holding that the Orphan Drug Act unambiguously requires that the FDA recognize the orphan exclusivity period regardless of a showing of clinical superiority. The FDA may further reevaluate the Orphan Drug Act and its regulations and policies. We do not know if, when, or how the FDA may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may make to its orphan drug regulations and policies, our business could be adversely impacted.
