  • If an original responder from week 16 (V7) completed the last visit Week 28 (EOS) or dropped to a EASI 50 score prior to Week 28.

• Women of childbearing potential (WOCBP)1 must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly for the duration of the trial and 16 weeks after last study drug administration. A list of contraception methods meeting these criteria is provided in the patient information.
