Aldeyra Therapeutics Achieves Primary Endpoint in Phase 3 Dry Eye Disease Clinical Trial of Reproxalap

New Drug Application Resubmission Anticipated in 2024

Lexington, Mass., August 08, 2024 – Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a biotechnology company devoted to discovering and developing innovative therapies designed to treat immune-mediated and metabolic diseases, today announced the achievement of the primary endpoint in a Phase 3 randomized, double-masked, vehicle-controlled dry eye chamber clinical trial of 0.25% reproxalap ophthalmic solution, an investigational new drug candidate, for the treatment of dry eye disease. Reproxalap was statistically superior to vehicle for the prespecified primary endpoint of ocular discomfort (P=0.004), a U.S. Food and Drug Administration (FDA)-accepted symptom of dry eye disease.

“To our knowledge, the results announced today represent the first positive Phase 3 clinical trial in a dry eye chamber with a symptom as a primary endpoint, and we believe that the results are supportive of the potential rapid clinical effect of reproxalap on reducing the ocular discomfort associated with dry eye disease,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra.

In the Phase 3 clinical trial, patients were administered vehicle (the drug product without the active ingredient) before and during exposure to a dry eye chamber in a manner that Aldeyra believes is consistent with the FDA’s dry eye disease draft guidance1. Qualifying patients were subsequently randomized to receive either reproxalap or vehicle before and during exposure to an additional dry eye chamber. Of the 132 patients randomized, 66 patients received reproxalap and 66 patients received vehicle. The primary endpoint was ocular discomfort, an FDA-accepted symptom of dry eye disease, from 80 to 100 minutes in the chamber. The dry eye chamber clinical trial was designed to satisfy the FDA’s New Drug Application (NDA) resubmission requirement, identified in the previously received complete response letter, of “at least one additional adequate and well-controlled study to demonstrate a positive effect on the treatment of ocular symptoms of dry eye.” Through the FDA Special Protocol Assessment process and additional comments, the FDA provided feedback on the clinical trial protocol and statistical plan.

To Aldeyra’s knowledge, in patients with dry eye disease, reproxalap is the first investigational drug with pivotal data supportive of acute and chronic activity in reducing symptoms, and the first investigational drug for chronic administration with pivotal data supportive of acute activity in reducing ocular redness. The potential NDA resubmission is anticipated in 2024. Based on FDA guidance, the resubmission NDA review period is expected to be six months.

There were no safety signals observed in the clinical trial, and reproxalap was observed to be well tolerated. Consistent with prior clinical trials, the most commonly reported adverse event was mild and transient instillation site discomfort. No treatment-related discontinuations were reported. Reproxalap has now been studied in over 2,500 patients.

About Aldeyra

Aldeyra Therapeutics is a biotechnology company devoted to discovering innovative therapies designed to treat immune-mediated and metabolic diseases. Our approach is to develop pharmaceuticals that modulate protein systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Our product candidates include RASP (reactive aldehyde species) modulators ADX-629, ADX-248, ADX-743, ADX-631, and chemically related molecules for the potential treatment of systemic and retinal immune-mediated and metabolic diseases. Our late-stage product candidates are reproxalap, a RASP modulator for the potential treatment of dry eye disease and allergic conjunctivitis, and ADX-2191, a novel formulation of intravitreal methotrexate for the potential treatment of retinitis pigmentosa.

About Reproxalap

Reproxalap is an investigational new drug candidate in development for the treatment of dry eye disease and allergic conjunctivitis, two of the largest markets in ophthalmology. Reproxalap is a first-in-class small-molecule modulator of RASP, which are elevated in ocular and systemic inflammatory diseases. The mechanism of action of reproxalap has been supported by the demonstration of statistically significant and clinically relevant activity in multiple physiologically distinct late-phase clinical indications. Reproxalap has been studied in more than 2,500 patients with no observed safety concerns; mild and transient instillation site irritation is the most commonly reported adverse event in clinical trials.
