Background:Atopic dermatitis(AD)affects approximately 10％of adults worldwide.CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling.This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods:This multicenter,randomized,double-blind,placebo-controlled,phase 2b trial was conducted in 21 medical institutions in China from February to November 2021.Totally 120 eligible patients were enrolled and randomized(1∶1∶1)to receive subcutaneous injections of 300 mg CM310,150 mg CM310,or placebo every 2 weeks for 16 weeks,followed by an 8-week follow-up period.The primary endpoint was the proportion of patients achieving ≥75％improvement in the Eczema Area and Severity Index(EASI-75)score from baseline at week 16.Safety and pharmacodynamics were also studied.Results:At week 16,the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups(70％[28/40]for high-dose and 65％[26/40]for low-dose)than that in the placebo group(20％[8/40]).The differences in EASI-75 response rate were 50％(high vs.placebo,95％CI 31％-69％)and 45％(low vs.placebo,95％CI 26％-64％),with both P values＜0.0001.CM310 at both doses also significantly improved the EASI score,Investigator's Global Assessment score,daily peak pruritus Numerical Rating Scale,AD-affected body surface area,and Dermatology Life Quality Index compared with placebo.CM310 treatment reduced levels of thymus and activation-regulated chemokine,total immunoglobulin E,lactate dehydrogenase,and blood eosinophils.The incidence of treatment-emergent adverse events(TEAEs)was similar among all three groups,with the most common TEAEs reported being upper respiratory tract infection,atopic dermatitis,hyperlipidemia,and hyperuricemia.No severe adverse events were deemed to be attributed to CM310.Conclusion:CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.
