Brief Summary:
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.

Arm Intervention/treatment
Placebo Comparator: Placebo plus azathioprine
Placebo IV plus oral azathioprine 2 mg/kg/day; placebo administered on Days 0, 14, 28, and then every 28 days until the end of the study. If the results in the double-blind period show that belimumab is safe and effective, then participants have the option to receive treatment with belimumab in a 6-month open-label extension phase. Placebo patients who opt to participate in the extension will receive belimumab 10 mg/kg IV every 28 days plus oral azathioprine 2 mg/kg/day for an additional 6 months.
 Biological: Placebo

Drug: Azathioprine
Azathioprine
Experimental: Belimumab 10 mg/kg plus azathioprine
Belimumab 10 mg/kg IV plus oral azathioprine 2 mg/kg/day; belimumab administered on Days 0, 14, 28, and then every 28 days until the end of the study. If the results in the double-blind period show that belimumab is safe and effective, then participants have the option to continue treatment with belimumab in a 6-month open-label extension phase. Patients who opt to participate in the extension will continue to receive belimumab 10 mg/kg IV every 28 plus oral azathioprine 2 mg/kg/day days for an additional 6 months.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to First Relapse [ Time Frame: Approximately up to 4 years ]
    Time to relapse is defined as the number of days from Day 0 until the participant experienced a relapse (relapse date - treatment start date +1). Only post-baseline relapses were considered in these analyses. Only relapses occurring up to and including the last visit date in the double-blind treatment period were considered in these analyses. Intent-to-treat population comprised of all randomized participants who received at least one dose of study agent (belimumab or placebo). NA indicates that the data was not available as the Number of events is too low to estimate the value. Median and Inter-quartile range were presented and were based on Kaplan Meier estimates.


Secondary Outcome Measures :
  1. Number of Participants With Major Relapse During the Double-blind Phase of the Study [ Time Frame: Approximately up to 4 years ]
    Data for number of participants with major relapse [defined as experiencing at least 1 major Birmingham Vasculitis Activity Score (BVAS) item] during the double-bind phase of the study was reported. Analysis was performed using a Cox proportional hazard model.

Criteria

Key Inclusion Criteria:

  • Clinical diagnosis Wegener's granulomatosis or microscopic polyangiitis by Chapel Hill criteria.

  • Maintenance therapy on this study must start no more than 2 weeks after confirmation of remission.

Key Exclusion Criteria:

  • Pregnant or nursing.
  • Receipt of a B cell targeted therapy (other than rituximab) at anytime
  • Receipt of an investigational biological agent within the past 60 days.
  • Required management of acute or chronic infections within the past 60 days.
  • Current drug or alcohol abuse or dependence.
  • Current or past positive test for human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
