Responder and Partial Responders (RPR): Percentage of Participants From Monotherapy Studies (JAHL, JAHM) Who Achieved a Response of Investigator's Global Assessment (IGA) 0 or 1Primary· Weeks 16, 36 and 52
The IGA measures the investigator's global assessment of the participant's overall severity of their atopic dermatitis (AD), based on a static, numeric 5-point scale from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting, and lichenification.
The results were analyzed using non-responder imputation (NRI). All participants who either discontinued the study treatment or discontinued the study for any reason at any time were defined as non-responders for the NRI analysis for categorical variables su

Adverse events — posted to ClinicalTrials.gov
Time frame: Baseline through Week 200.
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of this study is to evaluate the long-term safety and efficacy of baricitinib in participants with atopic dermatitis.
Participants were enrolled in this study from the originating studies (JAHL, JAHM, JAIY) or were directly enrolled in the open-label arm.
