Brief Title  ICMJE Safety, Efficacy, and Tolerability Study of PF-06480605 in Subjects With Moderate to Severe Ulcerative Colitis.
Official Title  ICMJE A PHASE 2A, MULTICENTER, SINGLE ARM, OPEN- LABEL, TWO-STAGE, STUDY TO EVALUATE THE EFFICACY, SAFETY, TOLERABILITY AND PHARMACOKINETICS OF PF-06480605 IN SUBJECTS WITH MODERATE TO SEVERE ULCERATIVE COLITIS
Brief Summary The purpose of this study is to evaluate the safety, tolerability, and efficacy of PF-06480605 in subjects with moderate to severe ulcerative colitis.
Detailed Description This is a Phase 2a, single arm, two-stage study in subjects with moderate to severe ulcerative colitis. Subjects will receive 500 mg of PF-06480605 intravenously every 2 weeks for a total of 7 doses. Blood, stool, and tissue samples will be collected at various time points throughout the study to evaluate safety, tolerability, efficacy, pharmacokinetics, and immunogenicity. Duration of participation for subjects will be approximately 8 months.
