CRL for Aldeyra’s Reproxalap for Dry Eye
FDA has issued a complete response letter to Aldeyra Therapeutics for its NDA for reproxalap to treat the signs and symptoms of dry eye disease. A company statement says the CRL indicated that while no safety or manufacturing issues were identified, the NDA “failed to demonstrate efficacy in adequate and well-controlled studies in treating ocular symptoms associated with dry eye.” The letter said that at least one additional study should be conducted to demonstrate a positive effect. FDA also reportedly identified concerns with data from the trial submitted with the NDA that may have affected study result interpretation, possibly due to methodological issues.
The company says it expects to announce top-line results from two ongoing trials in the second quarter. “Subject to positive results and discussions with FDA, Aldeyra intends to resubmit the NDA mid-year 2025,” it says.
Reproxalap is described as an investigational drug candidate being developed to treat dry eye disease and allergic conjunctivitis. It is a first-in-class small molecule modulator of RASP, which are elevated in ocular and systemic inflammatory diseases.
