Press Release Details

LEXINGTON, Mass., June 6, 2017 /PRNewswire/ -- Aldeyra Therapeutics, Inc. (NASDAQ: ALDX) (Aldeyra), a clinical-stage biotechnology company devoted to treating inflammation, inborn errors of metabolism, and other diseases related to aldehydes, today announced that it has enrolled the first patient into a Phase 2a clinical trial of topical ocular ADX-102 for the treatment of Dry Eye Disease (DED).

"Dry Eye Disease is a common ocular inflammatory condition with high unmet medical need, representing one of the largest ophthalmic markets worldwide," commented Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. "Based on the success of ADX-102 in two ocular inflammation Phase 2 clinical trials announced last year, we are pleased to initiate clinical development in this disease, and we expect to report results in the third quarter of this year."

ADX-102 and other product candidates generated from Aldeyra's aldehyde trap platform sequester and facilitate the degradation of aldehydes, a class of endogenously generated pro-inflammatory mediators that are elevated in DED patients. The Phase 2a clinical trial will test three formulations of topical ocular ADX-102 over 28 days of dosing. Endpoints will include standard signs and symptoms characteristic of DED.

A clinical trial synopsis is available on clinicaltrials.gov (NCT03162783).

About Aldeyra Therapeutics

About Dry Eye Disease
Dry Eye Disease is a common inflammatory disease characterized by insufficient moisture and lubrication in the anterior surface of the eye. Symptoms may include ocular irritation, burning or stinging, and, in severe cases, decreased vision. In patients with Dry Eye Disease, aldehydes may contribute to ocular inflammation as well as the impairment of lipids (fats) that lubricate the surface of the eye.
