It’s déjà vu all over again for Aldeyra Therapeutics Inc., which disclosed its third complete response letter (CRL) for dry eye disease candidate reproxalap, with the U.S. FDA citing a lack of substantial and consistent evidence of efficacy.
Aldeyra Therapeutics Inc. is making another run at U.S. FDA clearance for reproxalap in dry eye disease (DED) after nailing the primary endpoint in a phase III randomized, double-masked, vehicle-controlled dry eye chamber trial of 0.25% ophthalmic solution.
Aldeyra Therapeutics Inc. is hoping that research already underway will satisfy the U.S. FDA, which delivered to the company another complete response letter (CRL) related to the NDA for reproxalap in dry eye disease (DED).
Aldeyra Therapeutics Inc. has bounced back from a complete response letter in November to produce positive phase III data for reproxalap in treating dry eye disease. The company is one of many developing treatments using diverse mechanisms of action.
Aldeyra Therapeutics Inc. has expanded its novel reactive aldehyde species (RASP) modulator pipeline with the discovery and advancement of new RASP modulators for the treatment of inflammatory and metabolic diseases.
As expected, Aldeyra Therapeutics Inc. received a complete response letter (CRL) from the U.S. FDA regarding its NDA for reproxalap in dry eye disease, with the agency requiring “at least one” additional study to prove efficacy of the reactive aldehyde species, or RASP, modulator.
Investors awaiting the announcement of a partnering deal for RASP modulator reproxalap ahead of the drug’s Nov. 23 PDUFA date were in for a rude awakening, as Aldeyra Therapeutics Inc. disclosed that the U.S. FDA had raised issues with the NDA, putting its imminent approval in dry eye disease in doubt. The update, disclosed in an SEC filing, sent shares (NASDAQ:ALDX) sinking 66%, or $3.60, to close Oct. 16 at $1.83.
In its newly issued complete response letter (CRL) to Aldeyra Therapeutics Inc., the U.S. FDA said there’s just not enough evidence of efficacy right now to approve ADX-2191, an injectable vitreous-compatible formulation of methotrexate to treat primary vitreoretinal lymphoma (PVRL).
With the drug already under review by the U.S. FDA for dry eye disease (DED), Aldeyra Therapeutics Inc.’s reproxalap hit statistical significance in the second phase III study for allergic conjunctivitis (AC), and the firm is mulling what CEO Todd Brady called the “high-class problem” of how to best commercialize the product. A partner may help puzzle that out.
Aldeyra Therapeutics Inc. is eyeing the start of clinical trials with reactive aldehyde species (RASP) modulators ADX-246 for systemic immune-mediated diseases and ADX-248 for geographic atrophy.
