Aldeyra Shares Fall as FDA Postpones Review of Key Drug Marketing Application
FDA Review Delay: Aldeyra Therapeutics experienced a ~12% drop in premarket trading after announcing a delay in the FDA review of its resubmitted marketing application for reproxalap, with a new target action date set for March 16, 2026.
Clinical Study Report Submission: The delay follows the company's submission of a clinical study report for a dry eye disease trial, which the FDA deemed a major amendment to the new drug application (NDA).
Trial Results: The trial did not meet its primary goal of improving dry eye symptoms, and Aldeyra submitted the safety data to the FDA in August.
Prospective Labeling: Despite the delay, the FDA has provided a draft of the prospective label for reproxalap, indicating that if no major deficiencies are found, the company will receive proposed labeling requests and potential postmarketing requirements.
