Rituximab Plus Cyclophosphamide Followed by Belimumab for the Treatment of Lupus Nephritis: a Randomized, Controlled Phase 2 Open Label Multicenter Study

IRB Number: 2015-038
(inactive trial)

Institutional Review Board, Hospital for Special Surgery

March 18, 2016

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.

This trial will be conducted as a  randomized  open label multicenter study in individuals with active lupus nephritis age 18 and older. There will be two treatment groups of a total of 40 participants.

The study treatment will include rituximab, cyclophosphamide (CTX), and Solumedrol. This treatment will be followed by prednisone and belimumab in one group, and by prednisone without belimumab in the other group. 

The total study duration will be 200 weeks. The enrollment period for this study will be 104 weeks. Study participation period will be 96 weeks, which includes a treatment phase of 48 weeks and an assessment phase of 48 weeks.
