Prospective, Observational Safety Study Of Patients With Granulomatosis With Polyangiitis (Wegener’s) Or Microscopic Polyangiitis Treated With Rituximab

IRB Number: 2014-273
(inactive trial)

Institutional Review Board, Hospital for Special Surgery

March 28, 2014

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.
