Aldeyra files application for Treatment of Primary Vitreoretinal Lymphoma

 -Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra) today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for ADX‑2191 (methotrexate injection, USP), an investigational drug candidate, for the treatment of primary vitreoretinal lymphoma, a rare but potentially fatal cancer with no FDA-approved therapy.

The NDA submission is supported by 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 for the prevention of 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
