Aldeyra Therapeutics Announces Positive Primary Vitreoretinal Lymphoma Pre-NDA Meeting with the FDA
ADX-2191, which has received FDA Orphan Drug Designation for the treatment of primary vitreoretinal lymphoma, is a novel, vitreous-compatible formulation of methotrexate.
Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra) today announced that, following the recent receipt of official minutes from its pre-NDA (New Drug Application) meeting with the U.S. Food and Drug Administration (FDA), the Company plans to submit an NDA as soon as the end of 2022 for marketing approval of the investigational drug candidate ADX-2191 for the treatment of primary vitreoretinal lymphoma.
“Pending FDA review, ADX-2191 could be the first FDA-approved therapy for primary vitreoretinal lymphoma, a rare but potentially fatal cancer with a median survival of less than five years,” stated Todd C. Brady, M.D., Ph.D., Aldeyra’s President and Chief Executive Officer.
ADX-2191, which has received FDA Orphan Drug Designation for the treatment of primary vitreoretinal lymphoma, is a novel, vitreous-compatible formulation of methotrexate. The planned NDA submission is expected to include a combination of published literature on the safety and efficacy of methotrexate for the treatment of primary vitreoretinal lymphoma and safety data from the recently completed Phase 3 GUARD Trial of ADX-2191 in proliferative vitreoretinopathy. During the Phase 3 GUARD Trial, no safety signals were observed, and ADX-2191 was well tolerated; there were no observed treatment-emergent serious adverse events. The most common adverse event associated with ADX-2191 treatment was punctate keratitis, a frequently observed side effect of intravitreal methotrexate, that was most commonly mild in severity. In the Phase 3 GUARD Trial, the incidence of punctate keratitis with ADX-2191 administration was observed to be less than that previously reported with intravitreal injection of compounded methotrexate.1
Based on the pre-NDA meeting minutes, Aldeyra intends to request Priority Review designation, which reduces the review period in which the FDA aims to take action on an NDA to within 6 months (compared to 10 months under standard review). The designation is intended to direct overall attention and resources to the evaluation of applications for drugs that, if approved, would represent significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.
In addition to the planned NDA submission for ADX-2191 in primary vitreoretinal lymphoma, a Type C meeting with the FDA to discuss the completion of clinical development of ADX-2191 for the prevention of proliferative vitreoretinopathy is planned for the first half of 2023, and results from the Phase 2 clinical trial of ADX-2191 in retinitis pigmentosa are expected in the first half of 2023.
About ADX-2191
ADX-2191 (methotrexate injection, USP) is a sterile, non-compounded intravitreal formulation of methotrexate for the potential prevention or treatment of specific rare retinal diseases, including primary vitreoretinal lymphoma, proliferative vitreoretinopathy, and retinitis pigmentosa. The ADX-2191 intravitreal formulation is preservative-free, designed to be vitreous-compatible, and optimized for excipient composition, viscosity, density, tonicity, pH, concentration, and volume of administration. ADX-2191 has received FDA Orphan Drug Designation for the prevention of proliferative vitreoretinopathy, and the treatment of primary vitreoretinal lymphoma and retinitis pigmentosa.
About Primary Vitreoretinal Lymphoma
Primary vitreoretinal lymphoma is a rare, aggressive, and potentially fatal retinal cancer that is diagnosed in approximately 300 to 600 patients in the United States per year. The median survival for newly diagnosed patients is 4.83 years. The most common ocular complaints reported by patients include blurred vision, painless loss of vision, floaters, red eye, and photophobia. No approved treatments are currently available, though methotrexate represents the current standard of care.2
About Aldeyra
Aldeyra Therapeutics is a clinical-stage biotechnology company developing innovative therapies designed to treat immune-mediated diseases. Our approach is to discover pharmaceuticals that modulate immunological systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Our pre-commercial product candidates are reproxalap, a potential treatment for dry eye disease and allergic conjunctivitis, and ADX-2191, a potential treatment for primary vitreoretinal lymphoma, proliferative vitreoretinopathy, and other rare sight-threatening retinal diseases. In addition, we are developing other product candidates, including ADX-629 and chemically related molecules, for the potential treatment of systemic and retinal immune-mediated diseases.
