Aldeyra Therapeutics receives complete response letter from the US Food and Drug Administration for the reproxalap new drug application for the treatment of signs and symptoms of dry eye disease
17 March 2026 - Aldeyra Therapeutics today announced receipt of a complete response letter from the US FDA for the new drug application of reproxalap, an investigational drug candidate, for the treatment of dry eye disease.
The complete response letter stated that there is “a lack of substantial evidence consisting of adequate and well-controlled investigations … that the drug product will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in its proposed labeling” and that “the application has failed to demonstrate efficacy in adequate and well controlled studies in the treatment of signs and symptoms of dry eye disease.”
