摘要
BackgroundRandomized controlled trials have shown the efficacy and safety of brodalumab in patients with moderate to severe plaque psoriasis.ObjectiveTo evaluate the efficacy and safety of brodalumab through 120 weeks of treatment in the AMAGINE-2 trial.MethodsPatients received ustekinumab through week 52 followed by brodalumab 210 mg every 2 weeks, continuous brodalumab 210 mg every 2 weeks, or any dose of brodalumab. Efficacy data were reported through 120 weeks by using observed data, last observation carried forward, and nonresponder imputation analyses.ResultsOf patients who received brodalumab 210 mg every 2 weeks, 84.4%, 75.6%, and 61.1% achieved 75%, 90%, and 100% improvement from baseline in Psoriasis Area and Severity Index at 120 weeks (observed data analysis), respectively. Patients who received brodalumab 210 mg every 2 weeks after receiving ustekinumab through 52 weeks achieved a similar skin clearance response as patients who received continuous brodalumab 210 mg every 2 weeks. Safety through 120 weeks was comparable to that of the blinded study periods.LimitationsA large number of discontinuations toward the end of the study (31% in the final 6 months) were due to early termination and led to differences between observed data and nonresponder imputation results.ConclusionsBrodalumab is well tolerated and showed robust efficacy for more than 2 years.
