Press Release Details

LEXINGTON, Mass., July 12, 2018 /PRNewswire/ -- Aldeyra Therapeutics, Inc. (NASDAQ: ALDX) (Aldeyra), a biotechnology company devoted to the development of next-generation medicines to improve the lives of patients with immune-mediated diseases, announced that the last patient has completed dosing in Aldeyra's randomized, double-masked, vehicle-controlled, multi-center, parallel-group Phase 2b clinical trial of topical ocular reproxalap in dry eye disease.

"Dry eye disease, a persistently disturbing ocular inflammatory condition, represents one of the largest ophthalmic markets worldwide," commented Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra.  "Based on the positive results of our Phase 2a dry eye disease clinical trial, as well as our Phase 2 clinical successes in other ocular inflammatory disorders, we are pleased to complete dosing in our Phase 2b dry eye disease trial, which is designed to establish the drug concentration and patient group sizes for Phase 3 testing. We look forward to providing the top-line results from the trial later this year."

The Phase 2b clinical trial tested two concentrations of topical ocular reproxalap (0.1% and 0.25%) against vehicle over 12 weeks of treatment in 300 dry eye disease patients. The primary objective of the trial is to select a drug concentration for Phase 3 clinical testing, and to determine appropriate patient numbers for Phase 3 clinical testing, based on the activity of drug versus vehicle on standard dry eye disease signs and symptoms. 

In September 2017, Aldeyra announced that the results of a randomized, double-masked, parallel-group Phase 2a clinical trial of topical ocular reproxalap demonstrated statistically and clinically relevant improvement from baseline in multiple signs and symptoms associated with dry eye disease. Improvement in symptoms was noted as soon as one week following initiation of therapy. Tear RASP (pro-inflammatory reactive aldehyde species) biomarkers diminished over the course of treatment, and greater RASP reduction generally correlated with clinical response.

Results from the Phase 2b trial are expected to be announced in the second half of 2018. 

About Aldeyra Therapeutics
Aldeyra Therapeutics is developing next-generation medicines to improve the lives of patients with immune-mediated diseases. Aldeyra's lead product candidate, reproxalap, is a first-in-class treatment in late-stage development for dry eye disease and other forms of ocular inflammation. The company is also developing other product candidates for autoimmune and metabolic diseases. None of Aldeyra's product candidates have been approved for sale in the U.S. or elsewhere.

About Dry Eye Disease
Dry eye disease is a common and chronic inflammatory disease estimated to affect approximately 20 million people in the United States, and is characterized by insufficient moisture in the anterior surface of the eye, leading to dryness, inflammation, pain, discomfort, irritation, and, in severe cases, decreased vision. Among physicians and patients, existing therapy for dry eye disease is generally regarded as inadequate.
