Future Outlook

The company expects operating expenses, particularly R&D, to increase substantially as clinical trials for SkinJect™ and Teverelix continue. It anticipates incurring significant losses for the foreseeable future and may never become profitable, necessitating additional financing for R&D and commercialization. While believing it has access to capital, there is no assurance of availability or favorable terms. The company aims for Teverelix to be a first-in-market product for specific prostate cancer and AUR indications. Future healthcare reforms are expected to lead to reductions in funding, more rigorous coverage criteria, and downward pressure on product pricing. The company is evaluating the impact of new accounting standards on future financial disclosures.

Management Comments

• We are a clinical-stage, multi-strategy, life science and biotech company focused on investing in and accelerating the clinical development programs of novel and disruptive therapeutic assets.
• Our principal purpose is to advance the clinical development program of the Products, which include SkinJectTM a novel, minimally invasive treatment for basal cell carcinoma and potentially other common forms of non-melanoma skin cancer and Teverelix, a next generation gonadotrophin-releasing hormone ('GnRH') antagonist that is a potentially first in market product for cardiovascular high-risk prostate cancer patients and patients with first acute urinary retention ('AUR') episodes due to enlarged prostate.
• We also seek to opportunistically identify, evaluate and acquire accretive assets, properties or businesses.
• We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements.
• We have included important factors in the cautionary statements included in this prospectus, particularly the factors described in the 'Risk Factors' section of this prospectus, that could cause actual results or events to differ materially from the forward-looking statements that we make.
• Management believes that the estimates utilized in preparing the financial statements are reasonable, however, actual results could differ from those estimates.
• Management believes that the Company has access to additional capital resources through public and/or private equity offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements.
• The Company expects to continue to incur significant operating losses for the foreseeable future and may never become profitable.
• The conclusion of the [SKNJCT-001 Phase 1] study was that D-MNA patch was well tolerated with no evidence of dose limiting toxicity.
• The clinical study report concluded that SKNJCT-001 study met both its primary and secondary endpoints.
• Based on the mice and minipig pharmacokinetic data, we concluded that human systemic exposure to doxorubicin is unlikely through the application of the D-MNA.
• We believe BCC is a rational target for chemo-immunotherapy using D-MNAs.
• The findings of the interim analysis are preliminary and may or may not correlate with the findings of the study once completed.
• We expect our R&D expenses to increase substantially for the foreseeable future as we continue with the SKNJCT-003 study and trials.
• There can be no assurance that the Company will be able to complete its clinical trials, that the trials will be successful, or that the product will ultimately reach commercialization.
• We do not anticipate that we will declare or pay dividends in the foreseeable future on our common shares. Instead, we anticipate that all of our earnings will be used for the operation and growth of our business.

Industry Context

The company operates in the highly competitive and rapidly evolving biotechnology and pharmaceutical industry, facing larger, better-funded competitors. Its strategy of opportunistic acquisitions, such as Antev, and partnerships, like the non-binding MOU with Helix Nanotechnologies Inc. for mRNA-based vaccines, aligns with common industry practices to expand pipelines and leverage complementary technologies. For skin cancer, the company aims to provide a novel, minimally invasive alternative to current surgical and topical treatments, which have varying efficacy and side effects. In prostate cancer, Teverelix targets an unmet need for high-risk cardiovascular patients by offering a GnRH antagonist that avoids the testosterone surge associated with conventional agonists. The regulatory landscape, including FDA approvals and ongoing healthcare reform measures, significantly influences drug development, pricing, and market access across the industry.

Comparison to Industry Standards

• SkinJect™ for BCC aims to be a more robust alternative to current surgical and topical treatments. Existing topical treatments like imiquimod show 84% tumor-free status after 3 years, 5-fluorouracil 68%, and tazarotene 30.5%. SkinJect™ Phase 1 showed 6 out of 13 participants (46%) with complete responses, and Phase 2 interim analysis showed over 60% clinical clearance, suggesting potential for improved efficacy compared to some topical options, but direct comparison to surgical standards is not yet available.
• The D-MNA delivers doxorubicin at very low doses (e.g., 25g) compared to typical systemic doses (104-130mg), aiming for localized effect and reduced systemic toxicity, which could be a significant advantage over traditional chemotherapy approaches.
• Teverelix for prostate cancer/AUR aims to be a first-in-market product for cardiovascular high-risk prostate cancer patients and patients with first acute urinary retention (AUR) episodes due to enlarged prostate. Unlike GnRH agonists, Teverelix directly suppresses sex hormone production without an initial testosterone surge, potentially reducing cardiovascular risks, a key differentiator for high-risk patients.
• For AUR, there are currently no FDA-approved pharmacologic treatments to prevent recurrence; standard care involves catheterization, alpha-blockers, and surgery, all with significant risks. Teverelix aims to offer a novel non-surgical approach by shrinking the prostate and increasing urinary flow.
• Teverelix Phase 2a data showed testosterone suppression comparable to existing treatments (97.5% castration levels by day 29), with better tolerability and lower incidence of CV-related adverse events, suggesting a competitive profile, especially for the high-risk patient population.

Stakeholder Impact

• Shareholders face potential significant dilution from future equity financings, no anticipated dividends, and risk of share price volatility and decline due to small public float and future sales by selling shareholders. There is also difficulty for U.S. shareholders to enforce judgments against the company or Canadian-resident directors/officers.
• Employees are subject to intense competition for qualified personnel, and incentive provisions (stock options) may lose value if the share price is low. Job security could be a concern if the company curtails operations due to lack of financing.
• Future customers' acceptance of products depends on risk/benefit, price, and comparison to other treatments. Coverage and reimbursement from third-party payors are critical, with risks of reduced demand or pricing pressure from healthcare reforms.
• Creditors, including debenture holders, face risks of non-payment or delays if the company experiences financial difficulties, although proceeds from the SEPA are intended to repay debentures.
• Regulatory authorities will continue extensive scrutiny, and the company faces risks of non-compliance with regulations, leading to sanctions or delays. Increased reporting obligations as a U.S. public company add to compliance burdens.

Next Steps

• Continue SKNJCT-003 Phase 2 clinical study in the United States.
• Continue SKNJCT-004 Phase 2 clinical study in the UAE.
• Conduct Type C Meeting with FDA (requested for week of October 6, 2025) to discuss D-MNA product development and clinical pathway.

Key Dates

Recommendation

The company is a clinical-stage biotech with promising product candidates (SkinJect™ and Teverelix) showing positive early clinical data and regulatory progress (FDA 505(b)(2) pathway, Phase 2 studies underway). The acquisition of Antev expands its pipeline. However, it faces significant financial challenges, including substantial operating losses and an auditor's going concern warning, indicating high operational risk. While recent capital raises have improved liquidity, the company will require further financing, which could dilute existing shareholders. The current S-1 is for secondary sales, not primary capital. Given the early stage of development, high burn rate, and inherent risks of biotech, a 'Hold' recommendation is appropriate for investors who are already exposed and believe in the long-term potential, acknowledging the significant speculative nature and financial uncertainties. New investors should approach with extreme caution due to the going concern risk and the need for substantial future financing.
