Study to Evaluate Efficacy and Safety of PF-04965842 in Subjects Aged 12 Years And Older With Moderate to Severe Atopic Dermatitis

Summary

B7451012 is a Phase 3 study to evaluate PF-04965842 in patients aged 12 years and older with a minimum body weight of 40 kg who have moderate to severe atopic dermatitis. The efficacy and safety of two dosage strengths of PF-04965842, 100 mg and 200 mg taken orally once daily, will be evaluated relative to placebo over 12 weeks of study participation. Eligible patients will have an option to enter a long-term extension study after completing 12 weeks of treatment.
