Descriptive Information
Brief Title  ICMJE PF-06651600 for the Treatment of Alopecia Areata
Official Title  ICMJE A PHASE 2B/3 RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, DOSE-RANGING STUDY TO INVESTIGATE THE EFFICACY AND SAFETY OF PF-06651600 IN ADULT AND ADOLESCENT ALOPECIA AREATA (AA) SUBJECTS WITH 50% OR GREATER SCALP HAIR LOSS
Brief Summary This is a global Phase 2b/3 study to evaluate the safety and effectiveness of an investigational study drug (called PF-06651600) in adults and adolescents (12 years and older) who have 50% or greater scalp hair loss. The study is placebo-controlled, meaning that some patients entering the study will not receive active study drug but will receive tablets with no active ingredients (a placebo). This is a dose-ranging study, investigating 5 different dosing regimens. It will be double-blinded, meaning that the sponsor, the study doctors, the staff, and the patients will not know whether a patient is on active study drug (or the dose) or placebo.
