Risk Change Over Time
- Accounting & Financial Operations - Risk 1We have a limited operating history, have incurred significant losses since our inception and anticipate incurring increasing expenses and continuing losses for the foreseeable future. Our independent registered public accountants and management have expressed substantial doubt as to our ability to continue as a going concern. *
We are a commercial-stage medical device and Phase I clinical-stage pharmaceutical company with a limited operating history upon which you can evaluate our business and prospects. We have incurred significant losses since inception, including net losses of $19.9 million for the nine months ended September 30, 2024. As of September 30, 2024, we had an accumulated deficit of $269.4 million. We anticipate incurring increased sales and general and administrative expenses related to our operations and transition into a public company for the foreseeable future. Losses will likely continue and may increase in the future as we continue to incur significant expenses related to drug development. We may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in revenues, which would further increase our losses. In addition, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by clinical-stage pharmaceutical companies. If we are unable to achieve and/or sustain profitability, or if we are unable to achieve the growth that we expect from these efforts, it could have a material adverse effect on our business, financial condition or results of operations. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods.
Risk Highlights Q2, 2026
Risk Factors Full Breakdown - Total Risks 68
- Innovation / R&D - Risk 1We are early in our pharmaceutical development efforts for nelitolimod, and if we are unable to advance our product candidates, including nelitolimod in clinical development for any reason (including due to lack of funding), obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business, results of operations, financial condition and prospects may be materially adversely affected.
We are in the early stages of our development efforts and have only one product candidate, nelitolimod, in early clinical development. We have completed nelitolimod dosing in Phase 1 and Phase 1b clinical trials for UMLM, ICC and HCC, and locally- advanced pancreatic cancer. Based on physician and investigator interest, we are supporting two Investigator Initiated Trials with nelitolimod, one in patients with advanced HCC in combination with cryoablation, durvalumab and tremelimumab another in patients with resectable colorectal liver metastases. Due to the excessive costs of capital, we are looking for potential partners for funding to advance nelitolimod development in Phase II trials in one or more chosen indications based on the results of these early studies. Results will be available in 2026, and we will begin discussions on further clinical development. Phase II studies will require FDA authorization prior to initiation. Our ability to generate product revenues from our product candidate, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidate. The success of this product candidate will depend on several factors, including the following: - successful enrollment in clinical trials and completion of clinical trials and preclinical studies with favorable results;- clearance of INDs by the FDA or similar regulatory filings by comparable foreign regulatory authorities for the conduct of clinical trials of our product candidate and our proposed design of future clinical trials;- demonstrating the safety and efficacy in the proposed indications for use of our product candidate to the satisfaction of applicable regulatory authorities;- receipt of marketing approvals from applicable regulatory authorities, including New Drug Applications ("NDAs") from the FDA and maintaining such approvals;- making arrangements with third-party manufacturers for, or establishing, clinical and commercial manufacturing capabilities;- establishing sales, marketing and distribution capabilities and launching commercial sales of our product candidate, if and when approved, whether alone or in collaboration with others;- establishing and maintaining patent and trade secret protection or regulatory exclusivity for our product candidate;- maintaining an acceptable safety profile of our products following approval; and - building and maintaining an organization of people who can successfully develop our product candidate. The success of our business depends in part on the successful development, regulatory approval, and commercialization of our product candidate, nelitolimod, as well as any other future product candidates, which may never occur. We have not yet succeeded in, and we may not succeed in, obtaining marketing approval for nelitolimod. If we are unable to develop or obtain regulatory approval for nelitolimod, or if approved, successfully commercialize our product candidates, we may not be able to generate any revenue from our pharmaceutical development efforts and this may have a material adverse effect on our business, results of operations, financial condition and prospects.
- Innovation / R&D - Risk 2Clinical trials of our product candidates or potential product candidates may fail to produce results necessary to support regulatory clearance or authorization.
We incur substantial expense for, and devote significant time to, clinical trials but cannot be certain that the trials will ever result in commercial gains. We may experience significant setbacks in clinical trials, even after earlier clinical trials showed promising results, and failure can occur at any time during the clinical development process. Our products may produce undesirable adverse effects that could cause us, institutional review boards ("IRBs") or regulatory authorities to interrupt, delay or halt clinical trials. We, IRBs, the FDA, or another regulatory authority may suspend or terminate clinical trials at any time to avoid exposing trial participants to unacceptable health risks. Our clinical trials may produce negative or inconclusive results or may demonstrate a lack of effect of our product candidates. Additionally, the FDA may disagree with our interpretation of the data from our pilot studies and clinical trials, or may find the clinical trial design, conduct or results inadequate to demonstrate safety or effectiveness, and may require us to pursue additional clinical trials, which could further delay the clearance or authorization of our product candidates. If we are unable to demonstrate the safety and effectiveness of product candidates in our clinical trials, we will be unable to obtain the regulatory clearances or authorizations we need to commercialize new products.
- Innovation / R&D - Risk 3Interim, "topline" and preliminary data from clinical trials of our product candidates may change as more patient data becomes available and are subject to confirmation, audit, and verification procedures that could result in material changes in the final data.
From time to time, we may publish interim, topline or preliminary data from our 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 becomes available. Preliminary or topline 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, interim and preliminary data should be viewed with caution until the final data is available. Adverse differences between preliminary or interim data and final data could significantly harm our reputation and business prospects.
- Innovation / R&D - Risk 4Delays in clinical trials are common and have many causes, and any delay could result in increased costs to us and could jeopardize or delay our ability to obtain regulatory approval and commence future product sales. We may also find it difficult to enroll patients in our clinical trials, which could delay or prevent the development of our product candidates.
We may experience delays in clinical trials of our drug candidates. Planned clinical trials may not begin on time, have an effective design, enroll a sufficient number of patients or be completed on schedule, if at all. Our clinical trials have been and can be delayed for a variety of reasons, including: - inability to raise or delays in raising funding necessary to initiate or continue a trial;- delays in obtaining regulatory approval to commence a trial;- delays in reaching agreement with the FDA on final trial design;- imposition of a clinical hold for safety reasons or following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;- delays in reaching agreement on acceptable terms with prospective contract manufacturing organizations ("CMOs"), or contract research organizations ("CROs"), and clinical trial sites, or failure by such CMOs to complete the manufacturing of clinical trial materials or CROs to follow and carry out the clinical study protocol at each site in accordance with the terms of our agreements with them;- delays in obtaining required IRB, approval at each site;- difficulties or delays in having patients' complete participation in a trial or return for post-treatment follow-up;- clinical sites electing to terminate their participation in one of our clinical trials, which would likely have a detrimental effect on subject enrollment;- time required to add new clinical sites; or - delays by prospective CMOs to produce and deliver sufficient supply of clinical trial materials. If initiation or completion of our planned clinical trials is delayed for any of the above reasons or other reasons, our development costs may increase, our regulatory approval process could be delayed and our ability to commercialize and commence sales of our drug candidates could be materially harmed, which could have a material adverse effect on our business. In addition, identifying and qualifying patients to participate in clinical trials of our drug candidates is critical to our success. The timing of our clinical trials depends on the speed at which we can recruit patients to participate in testing our drug candidates as well as completion of required follow-up periods. We may not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired characteristics or to complete our clinical trials in a timely manner. Patient enrollment is and completion of the trials are affected by a variety of factors, including: - severity and prevalence of the disease under investigation;- design of the trial protocol;- size of the patient population;- eligibility criteria for the trial in question;- perceived risks and benefits of the drug candidate under trial;- proximity and availability of clinical trial sites for prospective patients;- availability of competing therapies and clinical trials;- efforts to facilitate timely enrollment in clinical trials;- patient referral practices of physicians; and - ability to monitor patients adequately during and after treatment.
- Innovation / R&D - Risk 5Use of toll-like receptor (TLR) agonist, including nelitolimod, may negatively impact the immune system. Serious adverse event data relating to TLR agonists may require us to reduce the scope of or discontinue certain of our pre-clinical or clinical activities.
Nelitolimod, an investigational agent in development, is a toll-like receptor 9 (TLR9) agonist which is believed to bind to the TLR9 receptors found on suppressive immune cells including myeloid-derived suppressor cells, antigen-presenting immune cells and other immune cells. TLRs play a key role in the innate immune system and create a bridge to adaptive immunity. It is believed that activating TLR9 primes immune cells to promote anti-tumor T-cells. If nelitolimod or any of our future product candidates in clinical trials or similar products from competitors produce serious adverse event data, we may be required to delay, discontinue or modify many of our clinical trials or our clinical trial strategy. If a safety risk based on mechanism of action or the molecular structure were identified, it may hinder our ability to develop our product candidates or enter into potential collaboration or commercial arrangements. Rare diseases and a numerical imbalance in cardiac adverse events have been observed in patients in our clinical trials. If adverse event data are found to apply to our TLR agonist and/or inhibitor technology as a whole, we may be required to significantly reduce the scope of or discontinue certain of our pre-clinical or clinical activities.
- Innovation / R&D - Risk 6The complexity of a combination product that includes a drug and a medical device presents additional, unique development and regulatory challenges, which may adversely impact our development plans and our ability to obtain regulatory approval or clearance of our product candidates.
We may decide to pursue marketing authorization for a combination product comprised of drug candidates and medical devices. A combination product includes, among other possibilities, a combination of a drug and device intended to be used together, according to their proposed labeling where both are required to achieve the intended use, indication or effect. Developing and obtaining regulatory approval or clearance for combination products pose unique challenges because they involve components that are regulated by the FDA pursuant to different regulatory frameworks and by different FDA centers. As a result, such products raise regulatory, policy and review management challenges. For example, because divisions from both FDA's Center for Drug Evaluation and Research and FDA's Center for Devices and Radiological Health must review submissions concerning product candidates that are combination products comprised of drug and devices, the regulatory review and approval for these products may be lengthened. In addition, differences in regulatory pathways for each component of a combination product can impact the regulatory processes for all aspects of product development and management, including clinical investigation, marketing applications, manufacturing and quality control, adverse event reporting, promotion and advertising, user fees and post-approval modifications. Similarly, the device components of our product candidates will require any necessary approvals or clearances or other marketing authorizations or certifications in other jurisdictions, which may prove challenging to obtain.
- Innovation / R&D - Risk 7We intend to use the FDA's expedited drug development programs for nelitolimod but may not be able to achieve expedited development or approval for this product candidate.
The FDA has established various expedited drug development programs to facilitate more rapid and efficient development, review and approval of certain types of drugs. Such programs include fast track designation, breakthrough therapy designation, accelerated approval, and priority review. We intend to use one or more expedited drug development programs for nelitolimod . The FDA has broad discretion on whether or not to admit a drug candidate for these programs, so even if we believe a particular product candidate is eligible for an expedited drug development program, we cannot assure you that the FDA would agree. Even if any of our product candidates is admitted to any of the expedited drug development programs, we may not experience a faster development process, review or approval compared to conventional FDA approval timelines, and the FDA may still decline to approve such product candidates. Fast track designation is designed to facilitate the development and expedite the review of therapies for serious conditions that fill an unmet medical need. Programs with fast track designation may benefit from early and frequent communications with the FDA, potential priority review and the ability to submit a rolling application for regulatory review. If any of our product candidates receive fast track designation but do not continue to meet the criteria for fast track designation, or if our clinical trials are delayed, suspended or terminated, or put on clinical hold due to unexpected adverse events or issues with clinical supply or due to other issues, we will not receive the benefits associated with the fast track program. Fast track designation alone does not guarantee qualification for the FDA's priority review procedures. FDA may award breakthrough therapy designation to a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or biologic may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. For product candidates that have been designated as breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Designation as a breakthrough therapy is within the discretion of the FDA. Even if one or more of our product candidates qualify as breakthrough therapies pursuant to FDA standards, the FDA may later decide that the product no longer meets the conditions for qualification. Thus, even though we may seek breakthrough therapy designation for one or more of our current or future product candidates, there can be no assurance that we will receive breakthrough therapy designation. If any of our programs or product candidates receive fast track or breakthrough therapy designation by the FDA or similar designations by other regulatory authorities, there is no assurance that we will receive any benefits from such programs or that we will continue to meet the criteria to maintain such designation. Even if we obtain such designations, we may not experience a faster development process, review or approval compared to conventional FDA procedures. A fast track or breakthrough therapy designation does not ensure that a product candidate will receive marketing approval or that approval will be granted within any particular time frame. In addition, the FDA may withdraw any such designation if it believes that the designation is no longer supported by data from our clinical development program upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application. The FDA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that our data is insufficient for approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of nelitolimod or any future product candidates. Any marketing approval we or our collaborators ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.
