Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AE) [ Time Frame: Up to 9 years ]
    An adverse event is defined as any unfavorable or unintended sign, symptom, or disease that is temporally associated with the use of a study agent but is not necessarily caused by the study agent. This includes worsening (example: increase in frequency or severity) of preexisting conditions. Participants with incidences of any event at any time post-baseline are presented by yearly interval. Only treatment-emergent AEs are summarized.

  2. AE Rates by System Organ Class (SOC) During the Study [ Time Frame: Up to 9 years ]
    AE rates by SOC adjusting for participant-years on study drug anytime post Baseline are summarized, which included the follow up visits. Only treatment-emergent AEs are summarized. The event rate of an AE was calculated as the number of events per 100 participant years. Participant years were calculated as sum across all participants ([last visit of interval day - first visit of interval day + 1] divided by365). Participant years excluded between study gaps if participant had not started extension study on date of last visit of parent study.

  3. Number of Participants With Serious Adverse Events (SAE) [ Time Frame: Up to 9 years ]
    An adverse event resulting in death, is life threatening (ie, an immediate threat to life), inpatient hospitalization, prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect or any other situation which is medically important is categorized as SAE. Only treatment-emergent AEs are summarized.

  4. SAE Rates by SOC During the Study [ Time Frame: Up to 9 years ]
    SAE rates by SOC adjusting for participants-years on study drug anytime post Baseline are summarized, which included the follow up visits. Only treatment-emergent SAEs are summarized. The event rate of an SAE was calculated as the number of events per 100 participant years. Participants years were calculated as = sum across all participants ([last visit of interval day - first visit of interval day + 1] divided by 365). Participants years excluded between study gaps if participant had not started extension study on date of last visit of parent study.

    The SLICC/ACR Damage Index was assessed every 48 weeks and at the exit visit as a measure of disease activity. It was developed to assess the accumulated damage since the onset of the disease. The number of participants with worsening in their SLICC/ACR Damage Index score compared with Baseline have been presented. Worsening was defined as a change in score (post-Baseline visit score - Baseline score) > 0. Baseline includes extension Year 1 Day 0 values for MITT participants treated with placebo in the parent study, and the last pre-treatment value in the parent study for MITT participants treated with Belimumab in the parent study. For years in which a participant was withdrawn from the study, the exit visit assessment was used in place of the Week 48 assessment for the year. This value was not carried forward through later years. Only those participants available at the specified time points (represented by n=X in the category titles) were analyzed.
