• Status: Completed
• Trial end date: 2020-10-07
• Target enrollment: 0
• Participant gender: All

Summary

B7451014 is a Phase 3 study to investigate PF-04965842 in patients aged 12 years and over with a minimum body weight of 40 kg who have moderate to severe atopic dermatitis. Subjects responding well to an initial open-label 12 week treatment of PF-04965842 (200 mg) taken orally once daily (QD) will be identified and randomized in a double-blind manner to receive 200 mg QD PF-04965842, 100 mg QD PF-04965842, or QD placebo. Efficacy and safety of 2 doses of PF-04965842 will be evaluated relative to placebo over 40 weeks. Subjects experiencing significant worsening of their symptoms, i.e., protocol-defined flare, enter 12 weeks rescue treatment and receive 200 mg PF-04965842 together with a marketed topical medicine. Eligible patients will have the option to enter a long-term extension study after completing the initial 12 week treatment, the 12 week rescue treatment, and the 40 week blinded treatment.
