• SOL-R evaluates repeat AXPAXLI™ dosing for wet age-related macular degeneration (wet AMD)
  
• Global non-inferiority study comparing AXPAXLI, dosed every six months, to 2 mg aflibercept every eight weeks

BEDFORD, Mass., July 30, 2024 (GLOBE NEWSWIRE) -- Ocular Therapeutix, Inc. (NASDAQ: OCUL, “Ocular”, the “Company”), a biopharmaceutical company committed to improving vision in the real world through the development and commercialization of innovative therapies for retinal diseases and other eye conditions, today announced that the first patients have been enrolled in the Phase 3 SOL-R clinical trial evaluating repeat dosing of AXPAXLI™ (axitinib intravitreal implant, also known as OTX-TKI) for the treatment of patients with wet age-related macular degeneration (wet AMD).

SOL-R is a global, 825-patient, non-inferiority study evaluating repeat dosing of AXPAXLI every six months (Q6M) compared to 2 mg aflibercept, dosed every eight weeks (Q8W) in patients with wet AMD. A third arm evaluating 8 mg aflibercept dosed Q6M is incorporated to ensure the study is adequately masked. The trial is evaluating AXPAXLI versus the current standard of care under the “real world” requirements of a repeat-dosing regimen.

“Our first Phase 3 trial, SOL-1, is intended to show that AXPAXLI can safely and durably maintain visual acuity in patients with wet AMD. SOL-R is intended to build on that by providing physicians with important evidence regarding the potential to re-dose AXPAXLI every six months, which better aligns with a likely ‘real world’ experience,” said Pravin U. Dugel, MD, Executive Chairman, President and Chief Executive Officer of Ocular Therapeutix. “SOL-R will initially enroll patients who do not qualify to be randomized in SOL-1. Subsequently, SOL-R will be opened to direct enrollment of patients who are treatment naïve or diagnosed with wet AMD within three months prior to enrollment. Patients enrolled in SOL-R are similar to those enrolled in our successful U.S. Phase 1 study, with further enrichment through multiple aflibercept loading doses. Further, these patients are evaluated to limit retinal fluid fluctuations between visits prior to randomization, increasing our confidence in the study’s potential success.”

“There is increasing evidence that pulsatile VEGF suppression may result in OCT fluctuations that could lead to poor long term visual outcomes. Even with new therapeutics entering the wet AMD market, the need for a durable and sustained treatment is substantial for many of my patients. The SOL-R study is critically important because results from this large, repeat-dosing study may provide the retina community with insight on how AXPAXLI may be used in our practices,” said Arshad M. Khanani, MD, MA, FASRS, Director of Clinic Research at Sierra Eye Associates, Reno, Nevada. “Providing patients who do not qualify for SOL-1 randomization with an opportunity to enroll in the SOL-R study is a tremendous service to physicians and the patients they serve. Moreover, I appreciate that SOL-R is designed for AXPAXLI re-treatment at six months, which is in-line with how often I’d ideally like to see my wet AMD patients. That said, it is not uncommon to reschedule appointments, leaving more time in between visits. Fortunately, SOL-1 is designed to generate valuable evidence to determine the ultimate durability of a single AXPAXLI implant. Together, these trials aim to provide a comprehensive picture of the flexibility of dosing intervals to meet individual patient needs.”

About AXPAXLI

AXPAXLI™ (axitinib intravitreal implant, also known as OTX-TKI) is an investigational bioresorbable, hydrogel implant incorporating axitinib, a small molecule, multi-target, tyrosine kinase inhibitor with anti-angiogenic properties, being evaluated for the treatment of wet AMD, diabetic retinopathy and other retinal diseases.

About the SOL-R study

The Phase 3 SOL-R trial (NCT06495918) is designed to evaluate the safety and efficacy of AXPAXLI in a multi-center, double-masked, randomized (2:2:1), three-arm study that will involve sites located in the U.S. and the rest of the world. The trial is intended to randomize approximately 825 patients who are treatment naïve or diagnosed with wet AMD in the study eye within three months prior to enrollment.

The one-year, non-inferiority study reflects a patient enrichment strategy that includes multiple loading doses of aflibercept and monitoring to exclude those with significant retinal fluid fluctuations. In the first arm, patients will be randomized to receive a single dose of AXPAXLI at Day 1 and re-dosed at Week 24. In the second arm, patients will receive aflibercept (2 mg) on-label every 8 weeks. In a third arm, patients will receive a single dose of aflibercept (8 mg) at Day 1 and re-dosed at Week 24, aligned to the AXPAXLI treatment arm for adequate masking. Subjects in any arm meeting pre-specified rescue criteria will receive a supplemental dose of aflibercept.

The primary endpoint is non-inferiority in mean best corrected visual acuity (BCVA) change from baseline between the AXPAXLI and on-label aflibercept (2 mg) arms at one year.

About Wet AMD

Wet age-related macular degeneration (wet AMD) is a leading cause of severe, irreversible vision loss affecting approximately 14 million individuals globally and 1.65 million in the United States alone (2023 Market Scope^® Retinal Pharmaceuticals Market Report). 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 40% patient discontinuation with continued disease progression. Taken together, these factors lead to undertreatment and a lack of vision improvement for patients.
