A Study of Abatacept in Patients With Active Ulcerative Colitis

Ulcerative Colitis Clinical Trial

Official title: A Phase 3, Multi-Center, Randomized, Placebo-Controlled Study to Evaluate the Clinical Efficacy and Safety of Induction and Maintenance Therapy With Abatacept in Subjects With Active Ulcerative Colitis (UC) Who Have Had an Inadequate Clinical Response and/or Intolerance to Medical Therapy

Status Completed

Clinical Trial Summary

The purpose of this clinical research study is to learn if abatacept can improve signs and symptoms of active ulcerative colitis in patients who have not had an adequate response to other therapies. The safety of this treatment will also be studied

Clinical Trial Description

The Induction Period First Cohort (IP1C) arms (30/10 mg/kg and 10 mg/kg) were placebo-controlled arms that were used for the primary endpoint and its analysis. The Induction Period Second Cohort arms (IP2C 30/10 mg/kg and 10 mg/kg) were not placebo-controlled, their sole purpose being to provide sufficient numbers of participants for the maintenance phase. The first cohort (IP1C) was randomized to receive placebo or 1 of 3 doses of abatacept. Following completion of the IP1C randomization, a second cohort (IP2C) was randomized to receive 1 of 2 doses of abatacept. After all participants in the IP1C completed or discontinued, the data was locked and the formal analysis for the Induction Period primary endpoint was performed. Summary tables for the second cohort (IP2C) and the Maintenance and Open-label phases were generated from a second, subsequent data lock. ;
