About ALDX
Aldeyra Therapeutics, Inc. is a biotechnology company focused on discovering therapies designed to treat immune-mediated and metabolic diseases.

Its late-stage product candidates are reproxalap, a RASP modulator for the potential treatment of dry eye disease and allergic conjunctivitis, and ADX-2191, a novel formulation of intravitreal methotrexate for the potential treatment of retinitis pigmentosa. ADX 629 is in Phase II clinical trials for moderate alcohol-associated hepatitis and Sjogren-Larsson Syndrome.
