Executive Commentary
"We sharpened our focus and embraced a single bold mission to redefine the retina experience. Despite established treatments, the burden of frequent dosing leads up to 40% of patients discontinuing treatment in the first year. AXPAXLI has the potential to disrupt this paradigm by offering a more sustainable solution with best-in-class durability."
Dr. Praveen Dugel, Executive Chairman, President and CEO
"The FDA approved an amendment to our SOL-1 trial incorporating re-dosing at weeks 52 and 76, unlocking potential for a 6 to 12-month dosing label. This allowed us to reduce SOL-R enrollment from 825 to 555 subjects while maintaining 90% statistical power, accelerating timelines and capital efficiency."

Strategic Positioning
1. Complementary Clinical Trial Design Enhances Regulatory and Commercial Value
Ocular’s dual Phase 3 trials, SOL-1 and SOL-R, were designed to provide comprehensive data on AXPAXLI’s durability and repeat dosing potential. SOL-1, a superiority study, evaluates single-dose efficacy to maintain vision at 36 weeks, now enhanced with re-dosing at weeks 52 and 76 to extend durability insights. SOL-R, a non-inferiority study, compares AXPAXLI dosed every 24 weeks against aflibercept every eight weeks, with a reduced enrollment target reflecting the added re-dosing data from SOL-1. This complementary approach is innovative in the retina space, enabling a robust regulatory submission and a differentiated label.
2. Trial Size Reduction and Accelerated Timelines Drive Capital Efficiency
The FDA-approved re-dosing amendment in SOL-1 enabled Ocular to reduce SOL-R enrollment by 33%, from 825 to 555 subjects, without compromising statistical power. This reduction is expected to expedite patient recruitment, data readout, and regulatory filings, enhancing capital efficiency. The retention rate in SOL-1 has been exceptional, supporting the streamlined approach. This operational agility positions Ocular to potentially bring AXPAXLI to market faster with a more attractive dosing regimen.
3. Potential 6 to 12-Month Dosing Label Positions AXPAXLI as Best-in-Class
The inclusion of re-dosing at 52 and 76 weeks in SOL-1 aims to support a label reflecting dosing flexibility between six and twelve months. This represents a significant improvement over current wet AMD therapies, which typically require more frequent injections with limited durability extensions. The potential for extended dosing intervals addresses a critical unmet need by reducing treatment burden and improving patient adherence, which historically suffers from up to 40% discontinuation within the first year.
4. Expanding Indications in Diabetic Retinopathy and Macular Edema
Beyond wet AMD, Ocular is advancing AXPAXLI into non-proliferative diabetic retinopathy (NPDR) and diabetic macular edema (DME). The positive Phase 1 HELIOS trial results and upcoming FDA feedback on trial design expected in the first half of 2025 highlight a strategic opportunity to address large underserved patient populations. Successful expansion into these indications could significantly broaden the commercial potential of AXPAXLI.
