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.
