Aldeyra Announces Positive Top-Line Phase 1 Clinical Trial Results and Clinical Development Plans for ADX-629
The Phase 1 clinical trial was a single-ascending and multiple-ascending dose trial to assess the pharmacokinetic, pharmacodynamic, safety, and tolerability profile of ADX-629 administered orally to healthy volunteers. Of the 85 subjects enrolled in the trial, 41 received ADX-629 orally as a single dose; 23 received ADX-629 orally twice per day for 10 days; and 21 received placebo. ADX-629 was well-tolerated, and no treatment-related adverse events were observed in the trial. No clinically meaningful changes were observed in vital signs, quantitative electrocardiography, or blood chemistry results. Clinically relevant plasma concentrations exceeding known levels of RASP were observed. Relative to subjects treated with placebo, reduction in the commonly described pro-inflammatory RASP malondialdehyde was observed in treated subjects.
“To our knowledge, ADX-629 is the first orally available and irreversible covalent inhibitor of pro-inflammatory RASP, and potentially represents a new paradigm in the understanding and treatment of immune-mediated disease,” stated
Unlike most currently available drugs, the RASP targets of ADX-629 are small molecules rather than proteins. As such, ADX-629 could represent a new pharmacotherapeutic approach with potential applications across a large number of immune-mediated diseases. RASP are upstream mediators of inflammation, regulating known mediators such as NF-κB, inflammasomes, and scavenger receptor A. ADX-629 covalently binds RASP, which are then degraded intracellularly. In animal models of cytokine storm, ADX-629 and structural analog reproxalap, now in Phase 3 clinical testing for certain inflammatory ocular diseases, have demonstrated reduction in the levels of a variety of pro-inflammatory cytokines, including TNF-α, IFN-γ, IL-1, and IL-17, while upregulating the principal anti-inflammatory cytokine, IL-10.
Aldeyra plans to facilitate the clinical testing of ADX-629 in patients with COVID-19-associated respiratory compromise by requesting a pre-investigational new drug meeting with the Infectious Disease Division of the
In addition, contingent on clinical research facility availability, which is currently limited due to COVID-19 precautions, Aldeyra plans to test ADX-629 in Phase 2 clinical trials of respiratory and dermal conditions associated with elevated levels of RASP, potentially including atopic asthma, chronic cough, psoriasis, and atopic dermatitis.
“We are excited to add potential new milestones to our clinical pipeline as we advance ADX-629 to Phase 2 clinical testing and expand our clinical development focus to include systemic disease,”
