About ALDX

Company Profile

ALDX logo image Aldeyra Therapeutics, Inc. is a biotechnology company, which engages in research and development activities with related general business planning, including raising capital. The company is headquartered in Lexington, Massachusetts and currently employs 9 full-time employees. The company went IPO on 2014-05-02. The firm's approach is to develop pharmaceuticals that modulate protein systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Its product candidates include reactive aldehyde species (RASP) modulators ADX-629, ADX 248, ADX-743, ADX-631, ADX-246, and chemically related molecules for the potential treatment of systemic and retinal 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.
