Description: ALDX Aldeyra The October 28, 2025

Aldeyra Therapeutics (NASDAQ: ALDX) is a U.S.-based biotech focused on immune-mediated and metabolic disorders. Its flagship asset, reproxalap-a reactive aldehyde species (RASP) modulator-is in a pivotal Phase III trial for dry-eye disease (DED) and allergic conjunctivitis. The company’s pipeline also includes ADX-2191 (a dihydrofolate reductase inhibitor for retinitis pigmentosa) and ADX-629, an oral RASP modulator currently in Phase II for COVID-19, atopic asthma, psoriasis, and alcohol intoxication, plus several preclinical RASP candidates (ADX 248, ADX 743, ADX 631, ADX 246). Aldeyra, incorporated in 2004 and renamed from Aldexa in 2014, is headquartered in Lexington, Massachusetts.

Key market and financial context: the global dry-eye disease market is projected to exceed $5 billion by 2028, offering a sizable addressable base for reproxalap; Aldeyra reported cash and equivalents of roughly $45 million as of its latest 10-Q, giving it an estimated 12-month runway assuming no additional financing; and biotech R&D spend has risen ~8 % YoY, indicating a favorable capital environment but also heightened competition for trial participants and talent.

Given the high attrition rates in ophthalmology Phase III trials (≈30 % success), Aldeyra’s progression to this stage is a material risk mitigant, yet the ultimate commercial upside hinges on regulatory clearance and market uptake versus entrenched therapies such as cyclosporine eye drops.
