Aldeyra Therapeutics is facing multiple class action lawsuits filed by Bronstein, Gewirtz & Grossman, LLC and Rosen Law Firm. The lawsuits allege that Aldeyra Therapeutics made false and/or misleading statements to investors between November 3, 2023, and March 16, 2026, concerning the inconsistent results of its reproxalap drug candidate's clinical trials. Investors who purchased Aldeyra Therapeutics securities during this period are encouraged to join the lawsuit, with a lead plaintiff deadline of May 29, 2026. The core of the complaint is that the purported positive findings from these trials were unreliable, rendering the company's statements about its business, operations, and prospects materially false and misleading.
