The study met primary and secondary endpoints with mostly mild-to-moderate adverse effects reported. The data were presented as a late-breaking oral presentation today at the American Academy of Dermatology Annual Meeting, taking place in New Orleans, March 17-21.\n\nIn the study “CBP-201, a next-generation IL-4Rα antibody, achieved all primary and secondary efficacy endpoints in the treatment of adults with moderate-to-severe atopic dermatitis (AD): A randomized, double-blind, pivotal trial in China (CBP-201-CN002),” researchers reported on results from Stage 1 of the pivotal China trial of CBP-201 in moderate-to-severe AD. This 16-week trial stage included 255 adults in the primary analysis population who received a 600 mg CBP-201 loading dose, followed by 300 mg CBP-201 every two weeks, compared to placebo. Patients on active therapy experienced rapid relief of symptoms, with a reduction in itch at Week 1 and significant improvement in all study endpoints by Week 4, which was sustained to Week 16. Furthermore, there was no plateau in IGA and EASI efficacy response at Week 16.\n\nSpecifically, the baseline median Eczema Area and Severity Index (EASI) was 26.9. 54.5% of patients were considered severe, with a baseline Investigators Global Assessment (IGA) score of 4. At 16 weeks, a greater proportion of patients treated with CBP-201 achieved an IGA score of 0-1 (clear or almost clear skin) and a 2 point IGA reduction than those on placebo (30.3% vs. 7.5%), meeting the study’s primary endpoint. 62.9% percent of CBP-201 patients achieved a 75% skin clearance (EASI-75), versus 23.4% in the placebo group and 35.8% achieve...
