“The promising results exhibited by ADX-629 represent the first clinical data supportive of RASP modulation as a novel pharmacology for the potential treatment of systemic disease,” stated
Top-Line Data from Phase 2 Proof-of-Concept Trials of ADX-629
Autoimmune Disease: Psoriasis
Following treatment of ten moderate psoriasis patients with ADX-629 for 12 weeks, psoriasis area and severity index (PASI) scores were statistically significantly decreased (p=0.0008 vs. baseline at Week 12), and peak PASI 50% and PASI 75% responder percentages were 57% (p=0.001) and 25% (p=0.051), respectively. Investigator global assessment scores decreased over the duration of treatment (p=0.01 vs. baseline at Week 12). Lesional pan-gene expression analysis suggested a trend toward normalization of global gene expression patterns; by Week 12 no gene expression pathways in lesional tissue were dysregulated compared to non-lesional skin. Plasma levels of the commonly described pro-inflammatory RASP malondialdehyde were reduced relative to baseline as soon as four weeks after initiation of treatment (p=0.02).
Allergic Inflammation: Asthma
In a placebo-controlled crossover trial of eight mild asthma patients treated for 7 days, asthma symptom scores and sputum eosinophil cell counts were numerically reduced following treatment with ADX-629 relative to treatment with placebo. Compared to placebo treatment, treatment with ADX-629 led to statistically significant reductions in plasma levels of the pro-inflammatory cytokines IL-5 (p=0.02) and TNFα (p<0.0001), and numerical reductions in plasma levels of malondialdehyde.
Infectious Disease: COVID-19
Following treatment of 11 mild to moderate COVID-19 patients with ADX-629 or placebo for four weeks, change from baseline in the
Across all three clinical trials, in patients treated with ADX-629, no safety concerns were evident from adverse events and there were no serious adverse events observed.
ADX-629 Advanced to New Indications
Today’s R&D Day will include a presentation from
Aldeyra also will announce the advancement of ADX-629 to new clinical development indications: ethanol toxicity; chronic cough; minimal change disease, a rare renal disease that commonly afflicts children; and Sjögren-Larsson Syndrome, a rare inborn error of aldehyde metabolism. Results from the ethanol toxicity trial are expected in the second half of 2022 and results from the chronic cough, minimal change disease, and Sjögren-Larsson Syndrome trials are expected in 2023.
