Aldeyra Therapeutics (NasdaqCM:ALDX) Earnings Call Presentation

Corporate Overview - Aldeyra Therapeutics focuses on developing innovative therapies for immune-mediated diseases by modulating protein systems rather than directly inhibiting single protein targets[7,8] - As of September 30, 2025, Aldeyra had $753 million in cash, cash equivalents, and marketable securities, expected to fund the company into the second half of 2027[10] RASP Modulation Platform - Aldeyra's approach involves modulating Reactive Aldehyde Species (RASP), which are formed by oxidation and bind to proteins, leading to pro-inflammatory signaling cascades[14] - RASP modulation allows for control of protein systems without completely turning single proteins on or off, potentially leading to broader activity with less toxicity[20,22] - ADX-629, an orally administered RASP modulator, has shown statistically significant changes in lipid profiles in multiple clinical trials, including a Phase 1 trial (P=0.005 for HDL), a Phase 2 psoriasis trial (P=0.036 for LDL/HDL ratio and P=0.0004 for FFA)[33] - ADX-248 binds to pro-inflammatory RASP HNE, leading to cytokine reduction in LPS-challenged mice and improved epidermal erosion scores in an oxazolone mouse model of atopic dermatitis (P=0.0093)[38] - ADX-248 increased brain dopamine and improved motor function in a preclinical Parkinson's disease model, with significant P values at different doses (P=0.05, P=0.001, P=0.004)[42] - ADX-246 binds to RASP retinaldehyde, reducing the toxic retinaldehyde metabolite A2E (P=0.04) in an Abcr knockout mouse model of dry AMD[44] Reproxalap - Reproxalap, a RASP modulator for dry eye disease, showed rapid activity in clinical trials and achieved the primary endpoint of ocular discomfort in a Phase 3 dry eye chamber trial (P=0.002)[48,53] - Aldeyra has an exclusive option agreement with AbbVie Inc for reproxalap, including a potential $100 million upfront payment, a $100 million milestone payment upon FDA approval in dry eye disease, and $200 million in additional regulatory and commercial milestones[61] - Phase 3 INVIGORATE allergen chamber trials for allergic conjunctivitis showed that reproxalap achieved the primary endpoint of patient-reported ocular itching with all P values < 0.0001[63] ADX-2191 - ADX-2191 has the potential to be the first approved drug for primary vitreoretinal lymphoma (PVRL), with approximately 200-600 new cases diagnosed in the United States per year[71]
