Summary: In this study, the Janus kinase/spleen tyrosine kinase inhibitor ASN002 reversed the lesional skin transcriptome toward a nonlesional phenotype. It also rapidly and significantly suppressed key inflammatory pathways implicated in AD pathogenesis, including TH2, TH17/TH22, and TH1 axes and barrier-related measures. Significant improvements in AD gene signatures were observed predominantly in the 40- and 80-mg dose groups. Smaller and largely nonsignificant molecular changes were seen in the 20-mg and placebo groups. In summary, ASN002 significantly suppressed key AD inflammatory pathways, corresponding to clinical response. This supports the potential for ASN002 as a novel therapeutic agent for moderate-to-severe AD.

Summary: ASN002 is an oral dual inhibitor of Janus kinase and spleen tyrosine kinase, which are involved in the pathogenesis of atopic dermatitis (AD) through their regulatory role on T helper (Th)1, Th2 and Th17/Th22 pathways. The objectives of this study were to evaluate the efficacy, safety, pharmacokinetics and effects on systemic biomarkers of ASN002 in patients with moderate-to-severe AD. A total of 36 patients with moderate-to-severe AD were randomized (3 : 1) to ASN002 or placebo in the phase Ib study. Three dosage cohorts were studied over a 28‑day period (20 mg, 40 mg and 80 mg once daily). ASN002 was superior to placebo for the proportion of patients achieving Eczema Area and Severity Index (EASI) 50, EASI 75 and in change from baseline in pruritus. Adverse events were generally mild and similar across all groups. ASN002 showed dose-dependent plasma exposure with low interpatient variability, significantly downregulated several serum biomarkers involved in Th1, Th2 and Th17/Th22 immunity, and decreased the atherosclerosis-associated biomarker E selectin/SELE. In summary, in patients with moderate-to-severe AD, ASN002 showed strong efficacy with rapid onset of action and associated improvements in systemic inflammation.
