Effectiveness of Belimumab Treatment in a Subpopulation of Systemic Lupus Erythematosus (SLE) Patients: a Pooled Analysis of BLISS-52 and BLISS-76

September 12, 2013 updated by: GlaxoSmithKline
This pooled analysis will assess data from the Phase 3 belimumab registration studies BLISS-52 (aka BEL110752) and BLISS-76 (aka BEL110751). The analysis was pre-planned and agreed prior to the unblinding of either study. The primary objective is to evaluate the impact of belimumab treatment on a more severe subpopulation of systemic lupus erythematosus (SLE) subjects from BLISS-52 and BLISS-76 to aid physicians and payers in decision making. Subjects are from the modified Intent-to-Treat (ITT) population defined as randomized subjects who received at least 1 dose of study agent. This more severe subpopulation will have renal, neurological, haematological, or cardiovascular/respiratory organ domain involvement (as defined by a British Isles Lupus Assessment Group (BILAG) domain score of A, B or C in at least one of the domains) at baseline AND anti-double-stranded deoxyribonucleic acid (anti-dsDNA) positive (≥ 30 IU/mL) at baseline OR low C3 and/or C4 complement relative to the normal range at baseline.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

ANA test results obtained in the screening period were only considered positive if the ANA titer ≥ 1:80 and/or anti-dsDNA serum antibody was ≥ 30 IU/mL
  • on a stable SLE treatment regimen for at least 30 days prior to Day 0, which consisted of any of the following (alone or in combination): prednisone or equivalent (from 0 to 40 mg/day when used in combination with other SLE treatment or from 7.5 to 40 mg/day alone), anti-malarials, non-steroidal anti inflammatory drugs (NSAIDs), or any immunosuppressive therapy (i.e., methotrexate, azathioprine, leflunomide, or mycophenolate calcineurin inhibitors, sirolimus, oral cyclophosphamide, 6-mercaptopurine, or thalidomide).

  • Additional inclusion criteria for the purpose of this analysis: subpopulation of patients from the pooled modified Intent-to-Treat population from BLISS-52 and BLISS-76 who have renal, neurological, haematological, or cardiovascular/respiratory organ domain involvement (as defined by a BILAG domain score of A, B or C in at least one of the domains) at baseline and 1 of the following:

    • are anti-dsDNA positive (≥ 30 IU/mL) at baseline, OR
    • have low C3 and/or C4 complement relative to the normal range at baseline.

Exclusion Criteria:

  • Key exclusion criteria for BLISS-52 and BLISS-76 included:
  • severe active lupus nephritis or Central Nervous System (CNS) lupus
  • pregnancy
  • receipt of any B cell target therapy at any time
  • receipt of an investigational agent within 60 days prior to Day 0 for non-biologics and within 1 year for biologics
  • receipt of abatacept (within 1 year), intravenous (IV) cyclophosphamide (within 6 months), anti-tumor necrosis factor (anti-TNF) therapy, anakinra, IV immunoglobulin (IVIG), prednisone > 100 mg/day, or plasmapheresis within 3 months, or live vaccine within 1 month.

Adults with systemic lupus erythematosus (SLE)

The ongoing SLE treatment regimen was to have been stable for at least 30 days prior to Day 0, which consisted of any of the following (alone or in combination): prednisone or equivalent (from 0 to 40 mg/day when used in combination with other SLE treatment or from 7.5 to 40 mg/day alone), anti-malarials, non-steroidal anti inflammatory drugs (NSAIDs), or any immunosuppressive therapy (ie, methotrexate, azathioprine, leflunomide, or mycophenolate calcineurin inhibitors, sirolimus, oral cyclophosphamide, 6-mercaptopurine, or thalidomide).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Responder Rate
Time Frame: Week 52
Response is defined as: ≥4 point reduction from baseline in SELENA SLEDAI score, no worsening (increase of < 0.30 points from baseline) in PGA, and no new BILAG A organ domain score or 2 new BILAG B organ domain scores.
Week 52

Secondary Outcome Measures

Secondary Outcome Measures
