Material Changes and Clinical Updates
Wet Age-Related Macular Degeneration (wet AMD) Program
- SOL-1 Trial (Phase 3):
- Status: Randomization of 344 subjects completed in December 2024.
- Retention: Exceeds 95% of randomized subjects remaining on-trial.
- Safety: No new or unexpected safety signals observed; >95% of rescue events met protocol criteria.
- Design: Compares AXPAXLI 450 µg to aflibercept 2 mg. Primary endpoint is visual acuity maintenance at Week 36.
- Timeline: Topline results expected in Q1 2026.
- SOL-R Trial (Phase 3):
- Status: Enrollment completed; randomization ongoing.
- Design: Three-arm trial (approx. 555 subjects) evaluating non-inferiority of AXPAXLI dosed every 24 weeks vs. aflibercept every 8 weeks.
- Timeline: Topline results expected in H1 2027.
- SOL-X Trial (Extension): Planned long-term, open-label extension for subjects completing SOL-1 or SOL-R safety follow-up to evaluate long-term safety and visual outcomes over an additional three years.
Non-Proliferative Diabetic Retinopathy (NPDR) Program
- Market Context: Company estimates <1% of U.S. NPDR patients are currently treated with approved anti-VEGF therapies.
- HELIOS-2 Trial (Phase 3):
- Status: FDA agreement received in August 2025 regarding trial design and novel ordinal endpoint.
- Design: ~432 subjects; compares AXPAXLI 450 µg to ranibizumab 0.3 mg.
- Endpoint: Ordinal 2-step Diabetic Retinopathy Severity Score (DRSS) change at Week 52.
- HELIOS-3 Trial (Phase 3):
- Design: ~930 subjects; three-arm superiority trial comparing AXPAXLI to sham comparator.
- Endpoint: Identical to HELIOS-2 (ordinal 2-step DRSS change at Week 52).
Intellectual Property
- Update: Received a notice of allowance from the U.S. Patent and Trademark Office in September 2025 for a patent covering methods of treating ocular diseases with AXPAXLI.
- Expiration: Expected to expire in 2044, absent extensions.
Guidance, Outlook, and Risks
Outlook: The Company plans to submit a New Drug Application (NDA) to the FDA for AXPAXLI for wet AMD following favorable topline data from both SOL-1 and SOL-R trials.
Risks and Contingencies:
- Regulatory Risk: FDA may not agree with trial designs, statistical analysis plans, or interpret data as supporting marketing approval despite prior SPA agreements.
- Clinical Risk: Preliminary or interim data may not be predictive of final results; long-term benefits in SOL-X are uncertain.
- Financial Risk: Uncertainty regarding cash runway and ability to fund future operations and clinical trials.
- Debt Risk: Existing indebtedness could be accelerated by creditors upon certain events of default.
Investor Verification Checklist
- Verify the sufficiency of the Company's cash runway to fund the SOL-1, SOL-R, HELIOS-2, and HELIOS-3 trials through completion.
- Confirm the specific terms of the Company's existing indebtedness and potential triggers for acceleration.
- Monitor the Q1 2026 topline data release for the SOL-1 trial to assess the probability of NDA submission.
- Review the final issued patent claims to ensure they align with the notice of allowance received in September 2025.
- Track enrollment progress in the SOL-R trial to ensure the H1 2027 data readout timeline remains feasible.
