Aldeyra Therapeutics Announces Positive Dry Eye Disease Pre-NDA Meeting with the FDA and Highlights Upcoming Corporate Milestones

LEXINGTON, Mass.--(BUSINESS WIRE)-- Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra) today announced that, following the recent receipt of official minutes from its pre-NDA (New Drug Application) meeting with the U.S. Food and Drug Administration (FDA), the Company remains on schedule to submit an NDA in the fourth quarter of 2022 requesting marketing approval of the novel RASP modulator reproxalap, an investigational new drug, for the treatment of dry eye disease.

“Based on the outcome of our pre-NDA meeting, we believe that we have aligned with the FDA on the content of the regulatory package that will support what we expect to be a uniquely comprehensive NDA submission for the treatment of dry eye disease, encompassing data demonstrating improvement that may occur within minutes of drug administration in symptoms and three different objective signs,” stated Todd C. Brady, M.D., Ph.D., Aldeyra’s President and Chief Executive Officer. “In contrast to currently available dry eye therapies that may require weeks of administration to achieve even modest benefit, the rapid onset of activity of reproxalap observed in clinical trials represents a potential paradigm shift in the treatment of dry eye disease.”

Consistent with prior guidance, with results from five adequate and well-controlled completed clinical trials, Aldeyra intends to submit the NDA with data for ocular dryness symptom score, ocular redness, Schirmer test, and Schirmer test ≥10 mm responder analysis. The NDA efficacy package is expected to include activity ranging from within minutes of drug administration to up to 12 weeks of treatment, crossover and parallel-group clinical trial designs, and assessment in dry eye chamber challenge and natural environment settings. In addition to efficacy data, Aldeyra plans to submit up to 12 months of safety data. Topical ocular reproxalap has been studied in more than 2,000 patients with no observed safety concerns; mild and transient instillation site irritation is the most commonly reported adverse event in clinical trials.

In addition to the planned NDA submission for reproxalap in dry eye disease, Aldeyra highlighted the following expected upcoming corporate milestones:

• The pre-NDA meeting for ADX-2191 for the treatment of primary vitreoretinal lymphoma has been scheduled for the fourth quarter of 2022.
• Results from Part 1 of the Phase 3 GUARD trial of ADX-2191 in proliferative vitreoretinopathy are expected in the third or fourth quarter of 2022.
• Results from the Phase 2 clinical trial of ADX-2191 in retinitis pigmentosa are expected in the first half of 2023.
• Results from the Phase 3 INVIGORATE-2 trial of reproxalap in allergic conjunctivitis are expected in 2023.

About Reproxalap

Reproxalap, an investigational new drug candidate, is a first-in-class small-molecule modulator of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease. Reproxalap’s mechanism of action has been supported by the demonstration of statistically significant and clinically relevant activity in multiple physiologically distinct late-phase clinical indications.

About Dry Eye Disease

Dry eye disease is a common inflammatory disease estimated to affect 39 million or more adults in the United States.¹ The disease is characterized by insufficient moisture and lubrication in the anterior surface of the eye, leading to dryness, inflammation, pain, discomfort, irritation, diminished quality of life, and in severe cases, permanent vision impairment. Among many physicians and patients, existing therapy for dry eye disease is generally regarded as inadequate and often requires weeks or months to demonstrate activity. In patients with dry eye disease, RASP may contribute to ocular inflammation, diminished tear production, ocular redness, and changes in tear lipid composition.² By diminishing RASP levels, Aldeyra’s lead RASP modulator reproxalap represents a novel and differentiated approach for the treatment of the symptoms and signs of dry eye disease.

About Aldeyra

Aldeyra is a clinical-stage biotechnology company developing innovative therapies designed to treat immune-mediated diseases. Our approach is to discover pharmaceuticals that modulate immunological systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Two of our lead product candidates, reproxalap and ADX-629, target pre-cytokine, systems-based mediators of inflammation known as RASP (reactive aldehyde species). Reproxalap is in late-stage clinical trials in patients with dry eye disease and allergic conjunctivitis. ADX-629, an orally administered RASP modulator, is in Phase 2 clinical testing for the treatment of systemic immune-mediated diseases. Our pipeline also includes ADX-2191 (intravitreal methotrexate 0.8%), in development for the prevention of proliferative vitreoretinopathy and the treatment of retinitis pigmentosa and primary vitreoretinal lymphoma.
