Ocular Therapeutix™ Announces FDA Agreement to Amend Special Protocol Assessment (SPA) for Pivotal Clinical Trial of AXPAXLI™ in Wet AMD

SPA amendment expands eligibility criteria for SOL clinical trial

Broadening of eligibility criteria anticipated to accelerate overall trial enrollment

BEDFORD, Mass., Jan. 25, 2024 (GLOBE NEWSWIRE) — Ocular Therapeutix, Inc. (NASDAQ:OCUL), a biopharmaceutical company focused on the formulation, development, and commercialization of innovative therapies for diseases and conditions of the eye, today announced that the U.S. Food and Drug Administration (FDA) has agreed to a Special Protocol Assessment (SPA) Agreement Modification for the Company’s pivotal Phase 3 SOL clinical trial of AXPAXLI™ (axitinib intravitreal implant, also known as OTX-TKI) for the treatment of wet age-related macular degeneration (wet AMD).

The SPA Agreement Modification enables the trial to include treatment-naïve wet AMD subjects with visual acuity of approximately 20/80 or better at the initial screening visit. After two aflibercept injections in the screening period, eligible participants would need to gain at least 10 ETDRS letters from the initial screening visit to Day 1 or achieve a visual acuity of approximately 20/20 or better at Day 1, in addition to satisfying other criteria, to qualify for enrollment in the trial. The SPA Agreement Modification also allows the pivotal trial to move forward, evaluating AXPAXLI with a single optimized implant with a drug load of 450 µg of a more soluble form of axitinib. This optimized configuration is expected to provide for a slightly increased daily release of the drug and is designed to improve synchronization of axitinib drug depletion with hydrogel bioresorption.

“With the changes reflected in the SPA Agreement Modification agreed to by the FDA, we believe we can accelerate the enrollment process for the SOL trial,” said Antony Mattessich, CEO of Ocular Therapeutix. “We have worked closely with the FDA to ensure that the SOL trial meets the agency’s updated guidance for wet AMD clinical trials, and we are eager to advance our engagement with clinical sites to enroll this trial under these new criteria.”

About AXPAXLI
AXPAXLI 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 and other retinal diseases.

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 1.6 million in the United States alone (2022 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 repeated intraocular injections every 1 to 4 months, treatment-related adverse events, patient compliance, and lack of vision improvement.
