New SOL-1 post-hoc analyses presented at VBS reinforce AXPAXLI’s unmatched durability in wet AMD with sustained disease control
AXPAXLI demonstrated robust CSFT control with a median time of 39 weeks and 46 weeks to ≥30 and ≥75 uM increases from Week 8
In all AXPAXLI subjects who had a vitreous floater AE, drug particles are no longer visible (mean time of 20 weeks)
Subjects treated with AXPAXLI generally maintained loading phase visual acuity gains up to Week 52 across quartile subgroups based on BCVA at screening
Company remains on track to submit NDA based on SOL-1 alone, subject to planned formal discussions with the U.S. FDA, consistent with recent FDA public commentary
BEDFORD, Ma., April 13, 2026 (GLOBE NEWSWIRE) -- Ocular Therapeutix, Inc. (NASDAQ: OCUL, “Ocular”), an integrated biopharmaceutical company committed to redefining the retina experience, today announced additional positive Week 52 data from the SOL-1 Phase 3 superiority trial of AXPAXLI (also known as OTX-TKI), its investigational product candidate for the treatment of wet age-related macular degeneration (wet AMD). The additional post-hoc analyses, presented at the 14th Annual Vit-Buckle Society (VBS) Meeting, reinforce the superior durability, strong sustained disease control, and generally well-tolerated safety seen with AXPAXLI in SOL-1.
“The new analyses of the SOL-1 Phase 3 data further strengthen our conviction in AXPAXLI’s potential to redefine retina treatment. A clear drug profile has emerged for AXPAXLI: a product candidate with durability that is unmatched in the wet AMD space while demonstrating excellent sustained disease control,” said Pravin U. Dugel, MD, Executive Chairman, President and Chief Executive Officer of Ocular Therapeutix. “Several analyses presented at VBS reinforce this profile. As retina specialists, anatomic control measured with OCT guides our treatment decisions. The time-to-CSFT increase analyses provide powerful additional evidence of AXPAXLI’s efficacy. After Week 8, it takes a median of 39 weeks to reach a clinically meaningful increase of ≥30 uM in CSFT, and even longer to reach ≥75 uM. This is simply an unprecedented level of sustained disease control and allows us to re-imagine the management of wet AMD for patients. These data continue to increase our confidence that AXPAXLI may be adopted broadly and immediately, if approved. Most importantly, we remain on track to submit our NDA based on SOL-1 alone, subject to planned formal U.S. FDA discussions. The FDA Commissioner recently noted that the Agency expects this new default framework for approval based on a single pivotal trial to be phased in over the next six months or so, aligning with our goal of bringing AXPAXLI to patients as soon as possible.”
Highlights from the data presented at VBS include:
- Strong overall efficacy profile with unmatched durability: Achieved statistical significance in the first three of five key secondary endpoints tested in hierarchical order. In addition, six other pre-specified secondary endpoints measuring clinically significant functional and anatomic outcomes were met with statistical significance.
- Sustained disease control (post-hoc analysis): Subjects in the AXPAXLI arm had significantly lower risk in anatomic worsening from Week 8 compared to the aflibercept (2 mg) arm. Week 8 was chosen to give both arms adequate time from the last aflibercept (2 mg) injection and start at a similar reference timepoint.
- The median time to ≥30 uM Central Subfield Thickness (CSFT) increase from Week 8 was 39 weeks in the AXPAXLI group and 16 weeks in the aflibercept (2 mg) group, a 23-week difference. An estimated hazard ratio of 0.7 indicates that, at any time from Week 8 to Week 52, subjects in the treatment group experienced a
30% lower risk of the event (descriptive p=0.0028) compared with the control group. - The median time to ≥75 uM CSFT increase from Week 8 was 46 weeks in the AXPAXLI group and 24 weeks in the aflibercept (2 mg) group, a 22-week difference. An estimated hazard ratio of 0.5 indicates that, at any time from Week 8 to Week 52, subjects in the treatment group experienced a
50% lower risk of the event (descriptive p<0.0001) compared with the control group.
- The median time to ≥30 uM Central Subfield Thickness (CSFT) increase from Week 8 was 39 weeks in the AXPAXLI group and 16 weeks in the aflibercept (2 mg) group, a 23-week difference. An estimated hazard ratio of 0.7 indicates that, at any time from Week 8 to Week 52, subjects in the treatment group experienced a
- Sustained visual outcomes (post-hoc analysis): Visual acuity gains achieved during the loading phase were generally maintained up to Week 52 with AXPAXLI across screening BCVA quartile subgroups. The magnitude of vision improvements was influenced by BCVA at screening. For example, AXPAXLI subjects in the lowest vision quartile group at screening had the greatest visual gains with +11.8 ETDRS letters compared to +8.5 letters in the aflibercept (2 mg) arm at Week 52. The mean vision at screening in this arm is similar to baseline BCVA in prior wet AMD studies. In comparison, subjects in the best vision quartile at screening had essentially no change in vision at Week 52 (-0.5 vs +1.1 letters; AXPAXLI vs aflibercept) as they started with almost 20/20 vision.
- Sustained visual outcomes in rescue-free subjects (post-hoc analysis): Observed difference for change in BCVA from baseline at Week 24 in the rescue-free subjects was -1.9 ETDRS letters in the AXPAXLI arm (+7.5 letters from screening) vs -2.6 letters in the aflibercept arm (+6.0 letters from screening). Of note,
81% of the AXPAXLI subjects were rescue-free at Week 24. At Week 36,75% of AXPAXLI subjects remained rescue-free and lost <1 additional letter from Week 24 (+6.6 letters from screening). - Well-tolerated profile: For all AXPAXLI subjects with a vitreous floater adverse event reported, drug particles are no longer visible (mean time of 20 weeks). Further analysis continues to illustrate the appearance of floaters corresponds closely to expected hydrogel bioresorption and drug elution without adversely affecting vision.
Andrew A. Moshfeghi, MD, MBA, FASRS, USC Roski Eye Institute commented, “What matters most to patients is preserving their vision - not just measuring change - and subjects treated with AXPAXLI in SOL-1 maintained excellent visual acuity throughout the study. The durability we are seeing is exceptional, with
Ocular Therapeutix remains on track to submit its New Drug Application (NDA) for AXPAXLI in wet AMD based on the SOL-1 trial alone, subject to planned formal discussions with U.S. FDA. This planned submission is consistent with recent FDA commentary, including a February 2026 New England Journal of Medicine editorial indicating that a single well-controlled Phase 3 trial is expected to become the new default standard for approval. In early-April, 2026, the FDA Commissioner further noted that this framework is anticipated to be phased in over the next six months, highlighting that the same statistical power can be achieved with a well-designed, well controlled, appropriately powered, single pivotal trial. These recent comments further reinforce the Company’s confidence in NDA acceptability based on SOL-1 alone, aligning with its goal of bringing AXPAXLI to patients as quickly as possible.
About AXPAXLI
AXPAXLI™ (also known as OTX-TKI) is an investigational, bioresorbable, intravitreal hydrogel incorporating axitinib, a small molecule, multi-target, tyrosine kinase inhibitor with anti-angiogenic properties, being evaluated for the treatment of wet AMD and diabetic retinal disease.
About the SOL-1 Trial
The registrational Phase 3 SOL-1 trial (NCT06223958) is designed to evaluate the safety and efficacy of AXPAXLI in a multi-center, double-masked, randomized (1:1), parallel group trial that involves more than 100 clinical trial sites located in the U.S. and Argentina. In December 2024, the trial completed randomization of 344 treatment-naïve subjects with a diagnosis of wet AMD in the study eye. Two randomized subjects withdrew from the trial prior to receiving Day 1 treatment.
The superiority trial has an eight-week loading segment prior to randomization. During the loading segment, subjects who have 20/80 vision or better and a central subfield thickness (CSFT) of ≤500 μm receive two doses of aflibercept (2 mg) at Week -8 and Week -4. Subjects who achieve best corrected visual acuity (BCVA) of 20/20 at Day 1 (baseline) or gain at least 10 Early Treatment Diabetic Retinopathy Study (ETDRS) letters at Day 1 along with a CSFT of ≤350 μm were then randomized to receive a single dose of AXPAXLI (0.45 mg) or a single dose of aflibercept (2 mg). At Week 52 and at Week 76, all subjects are re-dosed with their respective initial treatment of AXPAXLI (0.45 mg) or aflibercept (2 mg). Subjects will be followed for safety until the end of Week 104.
Throughout the trial, subjects are assessed monthly. Trial subjects and designated trial personnel will remain masked through the end of Week 104. The clinical trial protocol requires that, during the trial, subjects in either arm meeting the pre-specified rescue criteria, which includes a BCVA loss of ≥15 ETDRS letters from baseline or new vision-threatening macular hemorrhage, will receive a supplemental dose of aflibercept (2 mg). The protocol provides that after the first rescue injection, rescue therapy may be provided at investigator discretion per their clinical judgement.
The primary endpoint of SOL-1 is the proportion of subjects who maintain visual acuity, a loss of <15 ETDRS letters of BCVA from baseline, at Week 36. Predefined statistical rules were applied to adjust for treatment discontinuation or deviation as per the pre-specified statistical analysis plan. The trial remained masked following Week 36 and subjects were evaluated for treatment durability at Week 52. The trial is being conducted under a Special Protocol Assessment (SPA) agreement with the FDA.
In February 2026, Ocular reported positive SOL-1 Week 52 topline data. The superiority primary endpoint was met with
About Wet AMD
Wet age-related macular degeneration (wet AMD) is a leading cause of severe, irreversible vision loss affecting approximately 14.8 million individuals globally and 1.7 million in the United States alone. Wet AMD causes vision loss due to abnormal new blood vessel growth and hyperpermeability and associated retinal vascularity in the macula, which is primarily stimulated by local upregulation of vascular endothelial growth factor (VEGF). Without prompt and continuous treatment to control this exudative activity, patients develop irreversible vision loss. With proper treatment, patients may maintain visual function for a period of time and may temporarily regain lost vision. Challenges with current therapies include pulsatile, repeated intraocular injections, treatment-related adverse events and up to
