Phase 3, Multi-Center, Multinational, Randomized, Double-Blind, Study to Evaluate the Efficacy and Safety of Belimumab (HGS1006) in Combination with Azathioprine for the Maintenance of Remission in Wegener’s Granulomatosis and Microscopic Polyangiitis

The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

The purpose of this study is to evaluate the efficacy and safety of belimumab, in combination with azathioprine, for the maintenance of remission following a standard induction regimen in patients with Wegener's granulomatosis or microscopic polyangiitis. The random assignment in this study is "1 to 1" which means that participants have an equal chance of receiving belimumab or placebo. This is a multicenter study. The target enrollment across all sites is 400. At this site, we expect to enroll 8-10 patients. The study will be approximately 3 years in length
