Aldeyra Therapeutics' Reproxalap is now on its third NDA, which was filed in June 2025. It supposedly fixes prior trial flaws. ALDX believes a potential FDA acceptance could set a PDUFA date for December 2025. After that, AbbVie may pay $100 million upfront and share US profits if Reproxalap wins approval, which should materially de-risk its eventual commercialization.
Aldeyra Therapeutics (NASDAQ:ALDX) shares plummeted more than 70% after the biotechnology company received a letter of refusal from the Food and Drug Administration (FDA) for its investigational dry eye disease therapy reproxalap. The company said the rejection was based on insufficient evidence of efficacy in treating ocular symptoms associated with dry eye disease.
The U.S. Food and Drug Administration has declined to approve Aldeyra Therapeutics' treatment for dry eye disease, the company said on Thursday.
Aldeyra's reproxalap faced an FDA setback but showed positive trial results, leading to a resubmitted NDA with a PDUFA date of April 2025. Despite a controversial deal with AbbVie, Aldeyra remains financially solid, with $100M in cash and potential milestone payments. The DED market is strong, and reproxalap's data surpasses competitors, indicating significant undervaluation of Aldeyra's stock.
Aldeyra Therapeutics is finally nearing commercialization, attracting renewed attention from some analyst firms. Drug giant AbbVie has a significant option agreement on Aldeyra's primary pipeline asset that will likely be triggered upon FDA approval in April. An updated analysis around Aldeyra Therapeutics follows in the paragraphs below.
