  <brief_summary>
    <textblock>
      The purpose of this study is to evaluate the efficacy and safety of belimumab, in combination&#xD;
      with azathioprine, for the maintenance of remission following a standard induction regimen in&#xD;
      patients with Wegener's granulomatosis or microscopic polyangiitis. The random assignment in&#xD;
      this study is &quot;1 to 1&quot; which means that participants have an equal chance of receiving&#xD;
      belimumab or placebo.&#xD;

    <measure>Time to First Relapse</measure>
    <time_frame>Approximately up to 4 years</time_frame>
    <description>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.</description>

  <secondary_outcome>
    <measure>Number of Participants With Major Relapse During the Double-blind Phase of the Study</measure>
    <time_frame>Approximately up to 4 years</time_frame>
    <description>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.</description>

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.</description>

    <participant_flow>
      <recruitment_details>Participants with diagnosis of Granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) were randomized in this study. The study was conducted at 37 centers in 15 countries in North America, Central America, South America, Western Europe, Eastern Europe, and Australia during 20 March 2013 - 06 February 2017.</recruitment_details>
      <pre_assignment_details>A total of 164 participants were screened and 106 were enrolled and randomized in a 1:1 ratio to receive placebo or belimumab 10 milligram per kilogram (mg/kg). Of which, 105 received at least 1 dose of study agent and one participant was randomized in error.</pre_assignment_details>
      <group_list>
        <group group_id="P1">
          <title>Placebo</title>
          <description>Participants were administered induction therapy (corticosteroids and either cyclophosphamide or rituximab) in the 6 months leading up to randomization. After randomization, participants were administered matching placebo intravenously over 1 hour, at Day 0, 14, 28 and every 28 days thereafter until 12 months after the last subject was randomized. All participants received oral azathioprine at a target dose of 2 milligram per kilogram per day (mg/kg/day). In Belgium-only open-label extension, all participants received belimumab 10mg/day every 28 days until Week 24, with a final evaluation at Week 28.</description>

        <title>Time to First Relapse</title>
        <description>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.</description>

          <description>Participants were administered induction therapy (corticosteroids and either cyclophosphamide or rituximab) in the 6 months leading up to randomization. After randomization, participants were administered matching placebo intravenously over 1 hour, at Day 0, 14, 28 and every 28 days thereafter until 12 months after the last subject was randomized. All participants received oral azathioprine at a target dose of 2 milligram per kilogram per day (mg/kg/day). In Belgium-only open-label extension, all participants received belimumab 10mg/day every 28 days until Week 24, with a final evaluation at Week 28.</description>

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.
allocation: Randomized
intervention model: Parallel Assignment
primary purpose: Treatment
masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
measure: Time to First Relapse
time frame: Approximately up to 4 years
description: 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.
measure: Number of Participants With Major Relapse During the Double-blind Phase of the Study
time frame: Approximately up to 4 years
description: 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.
arm group label: Placebo plus azathioprine
arm group type: Placebo Comparator
description: 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.
arm group label: Belimumab 10 mg/kg plus azathioprine
arm group type: Experimental
description: 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.
