Key clinical point: Downtitrated baricitinib treatment was efficacious in most patients with moderate-to-severe atopic dermatitis (AD) through 16 weeks; clinically relevant efficacy was observed in most patients who were readministered the original dose due to downtitration or treatment withdrawal-related efficacy loss.
Major finding: In the 4-mg and 2-mg cohorts, 61% and 71% of patients maintained a validated Investigator’s Global Assessment for AD (vIGA-AD) score of 0/1/2 at downtitration week 16 and 80%/85%/88% and 90%/56%/86% of patients who switched to original dose in the continuous dosing/downtitration/treatment withdrawal group re-achieved vIGA-AD 0/1/2, respectively.
Study details: This BREEZE-AD3 trial substudy included 526 patients with moderate-to-severe AD treated with 4/2 mg baricitinib at trial entry who achieved vIGA-AD 0/1/2 at week 52, with each cohort being re-assigned to continuous dosing, downtitration, or treatment withdrawal.
