FDA grants orphan drug designation to ADX-2191 for retinitis pigmentosa

The FDA has granted orphan drug designation to ADX-2191 for the treatment of retinitis pigmentosa, according to a press release from Aldeyra Therapeutics.

Currently, there are no approved drug treatments for retinitis pigmentosa.

“ADX-2191 has now received orphan designations for three distinct clinical indications, highlighting the broad platform potential of ADX-2191 to treat an array of rare retinal disorders,” Todd C. Brady, MD, PhD, president and CEO of Aldeyra, said in the release.

ADX-2191 (methotrexate for intravitreal injection) previously received the designation to treat primary vitreoretinal lymphoma and to prevent proliferative vitreoretinopathy.
