Primary Outcome Measures:
  • SYSTEMIC LUPUS ERYTHEMATOSUS RESPONDER INDEX (SRI) RESPONSE RATE WITH THE MODIFIED SYSTEMIC LUPUS ERYTHEMATOSUS DISEASE ACTIVITY INDEX (SLEDAI)-2000 SCORING FOR PROTEINURIA AT WEEK 52 [ Time Frame: At Week 52 ]
    SRI response is defined as subjects with>=4 point reduction from baseline in SELENA SLEDAI score (with the modified SLEDAI-2000 scoring for proteinuria), and no worsening (increase of <0.30 points from baseline) in Physician's Global Assessment (PGA), and no new British Isles Lupus Assessment Group (BILAG) A organ domain score or 2 new BILAG B organ domain scores compared with baseline at the time of assessment (i.e., at Week 52).


Secondary Outcome Measures:
  • SRI RESPONSE RATE WITH THE SELENA SLEDAI FOR SCORING OF PROTEINURIA AT WEEK 52 [ Time Frame: At Week 52 ]
    SRI response is defined as subjects with>=4 point reduction from baseline in SELENA SLEDAI score, and 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 compared with baseline at the time of assessment (i.e., at Week 52).

  • TIME TO FIRST SEVERE FLARE (SLE FLARE INDEX) [ Time Frame: Baseline and up to 52 weeks ]
    Time to first severe flare (as measured by the modified SLE Flare Index[SFI]); with SLEDAI-2000 and SELENA SLEDAI as the SLEDAI criterion of the SFI, over 52 weeks will be compared between the treatment groups. Analysis will be performed using Cox proportional hazard model.

  • REDUCTION IN PREDNISONE DOSE [ Time Frame: Baseline and up to Week 52 ]
    Percent of subjects whose average prednisone dose has been reduced by >= 25% from baseline to <= 7.5 milligrams (mg)/day during Weeks 40 through 52 in subjects receiving greater than 7.5 mg/day at baseline.

  • NUMBER OF PARTICIPANTS WITH ADVERSE EVENTS (AES), SERIOUS AES, SEVERE AES AND AES LEADING TO DICSONTINUATION [ Time Frame: Up to 84 weeks ]
    An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations judged by physician, is associated with liver injury and impaired liver function.

  • NUMBER OF PARTICIPANTS WITH LABORATORY ABNORMALITIES [ Time Frame: Up to 84 weeks ]
    Number of participants with abnormalities in hematology, clinical chemistry and urinalysis will be summarized.

Detailed Description:
Study participants receive stable standard therapy for lupus in addition to receiving either placebo (no active medicine) or belimumab. The controlled period of the study is 52 weeks. The random assignment in this study is "2 to 1" which means that for every 3 participants, 2 will receive belimumab and 1 will receive placebo. Participants who successfully complete the 52-week study may enter into a 6-month open-label extension. All participants in the open-label extension receive belimumab plus standard therapy.
  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • At least 18 years of age.
  • Self-identified black race.
  • Have a clinical diagnosis of SLE according to the American College of Rheumatology (ACR) criteria
  • Have active SLE disease defined as a SELENA SLEDAI score >= 8 at screening
  • Have 2 unequivocally positive autoantibody test results defined as a positive antinuclear antibody (ANA) test [i.e., titer >= 1:80 by human epithelial cell line 2 (HEp-2) immunofluorescence assay (IFA) and/or positive enzyme immunoassay (EIA)] and/or a positive anti- double stranded deoxyribonucleic acid (dsDNA) (>= 30 international units [IU]/milliliter [mL]) serum antibody test as follows:

    • From 2 independent time points within the study screening period. Screening results must be based on the study's central laboratory results, OR
    • One positive historical test result and 1 positive test result during the screening period.

Historical documentation of a positive ANA test (e.g., HEp-2 IFA or EIA) or anti-dsDNA (eg, anti-dsDNA by any validated commercial assay) must include the date and type of the test, the name of the testing laboratory, numerical reference range, and a key that explains values provided as positive versus negative OR negative, equivocal/borderline positive). Only unequivocally positive values as defined in the laboratory's reference range are acceptable; borderline values will not be accepted.

  • On a stable SLE treatment regimen consisting of any of the following medications (alone or in combination) for a period of at least 30 days prior to Day 0 (i.e., day of 1st dose of study agent):

    • Corticosteroids (prednisone or prednisone equivalent, up to 40 mg/day): For subjects on SLE combination therapy, their stable steroid dose must be fixed within the range of 0 to 40 mg/day (prednisone or prednisone equivalent). For subjects whose only SLE treatment is steroids, their stable steroid dose must be fixed within the range of 7.5 to 40 mg/day (prednisone or prednisone equivalent). For those subjects on alternating day doses of steroids, use the average of 2 daily doses to calculate the average daily steroid dose.
    • Other immunosuppressive or immunomodulatory agents including methotrexate, azathioprine, leflunomide, mycophenolate (including mycophenolate mofetil, mycophenolate mofetil hydrochloride, and mycophenolate sodium), calcineurin inhibitors (e.g., tacrolimus, cyclosporine), sirolimus, oral cyclophosphamide, 6-mercaptopurine, mizoribine, or thalidomide.
    • Anti-malarials (e.g., hydroxychloroquine, chloroquine, quinacrine).
    • Non-steroidal anti-inflammatory drugs (NSAIDs).

Note:

  • Pre-existing SLE medications must be stable for at least 30 days prior to Day 0.
  • Corticosteroids may be added as new medication or their doses adjusted only up to 30 days prior to Day 0.
  • New SLE therapy other than corticosteroids must not be added within 60 days of Day 0.
  • A female subject is eligible to enter the study if she is:

    • Not pregnant or nursing;
    • Of non-childbearing potential defined as: pre-menopausal females with a documented tubal ligation, hysterectomy, documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, or documented bilateral oophorectomy, OR postmenopausal defined as 12 months of spontaneous amenorrhea with an appropriate clinical profile [e.g., > 45 years, in the absence of hormone replacement therapy or other cause for amenorrhea]; in questionable cases obtain a blood sample for follicle stimulating hormone (FSH) and estradiol simultaneously to confirm. Diagnostic levels for FSH and estradiol vary by specific laboratories/assays;
    • OR is of child-bearing potential with negative pregnancy test as determined by serum human chorionic gonadotrophin (hCG) test at screening and urine hCG test prior to dosing AND agrees to use one of the contraception methods for 2 weeks prior to the day of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until 16 weeks following the last dose of study agent.
    • OR has only same-sex partners, when this is her preferred and usual lifestyle.
    • Have the ability to understand the requirements of the study, provide written informed consent (including consent for the use and disclosure of research-related health information), and comply with the study protocol procedures (including required study visits).
