LEXINGTON, MA, USA I December 19, 2023 I Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a biotechnology company devoted to discovering and developing innovative therapies designed to treat immune-mediated diseases, today announced positive top-line results from a Phase 2 clinical trial of ADX-629, an investigational RASP modulator, in patients with atopic dermatitis. Relative to baseline, the clinical trial demonstrated statistically significant and clinically relevant improvement in investigator-assessed and patient-reported outcomes across a number of different physiological and psychosocial assessments, including complete resolution of affected body surface area observed in one patient and elimination of itching reported by two patients.
“The demand for safe, tolerable, and orally administered atopic dermatitis therapies, particularly for mild to moderate patients, is substantial,” stated Dr. Matthew Zirwas, founder of the Bexley Dermatology Research clinic and Board-certified dermatologist who served as Principal Investigator of the clinical trial. “The data announced today offer a glimpse into what may be possible for many patients who today are not adequately treated.”
An open-label, single-center Phase 2 clinical trial of ADX-629 was conducted in eight mild to moderate atopic dermatitis patients. Over three months of treatment, patients received 250mg ADX-629, administered orally twice daily. The primary endpoint of the clinical trial was safety and tolerability. Secondary endpoints included Eczema Area and Severity Index (EASI), Investigator Global Assessment (IGA), Patient-Oriented Eczema Measure (POEM), Peak Pruritus Numerical Rating Scale, time to flare, Hamilton Depression Rating Scale (HAM-D), and Beck Anxiety Inventory (BAI).
Relative to baseline, over three months of treatment, improvement was observed in all patients. Statistical significance was achieved for improvement in EASI (p=0.0006). EASI thresholds for 50% improvement (EASI‑50), 75% improvement (EASI-75), and 90% improvement (EASI-90) were met in four patients (50%), three patients (38%), and one patient (13%), respectively. Statistical significance was achieved for improvement in affected body surface area (p<0.0001); one patient (13%) achieved complete clearance of affected body surface area. Statistical significance was achieved for improvement in IGA (p<0.0001). The IGA threshold score of 0 (clear) or 1 (almost clear) was met in one (13%) patient. Statistical significance was achieved for improvement in patient-reported itching (p=0.0002); the clinically relevant threshold of improvement by 4 or more points was met in three patients (38%), and two patients (25%) reported elimination of itching. Statistical significance was achieved for improvement in patient-reported eczema severity (POEM, p<0.0001); the clinically relevant threshold of improvement by 4 or more points was met in six patients (75%). Statistical significance was achieved for improvement in depression (HAM-D, p=0.02) and numerical improvement was observed for improvement in anxiety (BAI, p=0.1).
All enrolled patients completed the trial per protocol. No patients experienced flare requiring rescue therapy. Only two adverse events deemed to be at least possibly related to ADX-629 were reported, and both events were mild. There were no observed serious adverse events or discontinuations due to adverse events.
“The results from the clinical trial of ADX‑629 in atopic dermatitis are consistent with activity demonstrated in previously disclosed clinical trials of ADX‑629, including Phase 2 clinical trials in psoriasis, asthma, and chronic cough, adding to a growing body of evidence that we believe is supportive of the activity of RASP modulators in systemic diseases associated with inflammation,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “Based on the signal-finding activity of ADX‑629, we enthusiastically plan to advance our next-generation investigational RASP modulator ADX‑246 to Phase 1/2 clinical testing in healthy volunteers and patients with atopic dermatitis.”
Aldeyra expects to initiate a multicenter, randomized, placebo-controlled Phase 1/2 clinical trial of ADX‑246 in healthy volunteers and patients with atopic dermatitis in the first half of 2024. Topline results from the trial are expected in the second half of 2024.
Conference Call & Webcast Information
Aldeyra will host a conference call at 8:00 a.m. ET today, December 19, 2023, to discuss the top-line results of the Phase 2 clinical trial of ADX-629 in atopic dermatitis. The dial-in numbers are (888) 415-4305 for domestic callers and (646) 960-0336 for international callers. The access code is 5858366. A live audio webcast of the conference call also will be accessible from the “Investors & Media” section of Aldeyra’s website at ir.aldeyra.com. A live webcast of the conference call will be available on the Investor Relations page of the company’s website at https://ir.aldeyra.com.

About Aldeyra
Aldeyra Therapeutics is a biotechnology company devoted to discovering innovative therapies designed to treat immune-mediated diseases. Our approach is to develop pharmaceuticals that modulate immunological systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Our product candidates include RASP (reactive aldehyde species) modulators ADX‑629, ADX‑246, ADX‑248, and chemically related molecules for the potential treatment of systemic and retinal immune-mediated diseases. Our pre-commercial 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 proliferative vitreoretinopathy and retinitis pigmentosa.
About ADX-629 and ADX-246
ADX-629 is an orally administered RASP modulator currently in development as a signal-finding molecule for the treatment of mass-market immune-mediated diseases. ADX‑629 has demonstrated potential activity in clinical trials of patients with psoriasis, asthma, COVID, ethanol toxicity, chronic cough, and atopic dermatitis. In more than 100 healthy volunteers and patients, no consistent adverse events associated with ADX‑629 have been identified. An analog of ADX-629, ADX‑246 is an orally administered next-generation RASP modulator expected to initiate clinical testing in the first half of 2024 in a Phase 1/2 clinical trial in healthy volunteers and patients with atopic dermatitis. Top-line results from the Phase 1/2 clinical trial are expected in the second half of 2024.
