Primary Outcome Measures:
  • Number of Participants With the Indicated Type of Adverse Event (AEs) and Serious Adverse Event (SAEs) [ Time Frame: Approximately up to 13 years ]
    An AE 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 [eg], increase in frequency or severity) of pre-existing conditions. An SAE is defined as an AE resulting in any of the following outcomes: death, is life threatening (that is, an immediate threat to life), inpatient hospitalization, prolongation of an existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, and is medically important.

  • Adverse Event (AE) Rates by System Organ Class (SOC) During the Study [ Time Frame: Approximately up to 13 years ]
    AE rates by SOC adjusting for participant-years on study drug anytime post Baseline are summarized, which included the follow up visits. Only treatmentemergent AEs are summarized. The Baseline is defined as the last available value prior to belimumab start date, for participants treated with placebo in the parent study and last pre-treatment value in the parent study for participants treated with belimumab in the parent study. The event rate of an AE was calculated as the number of events per 100 participant years: Event Rate=100* number of events divided by participant years. Participant years were calculated as sum across all participants ([last visit of interval day minus first visit of interval day plus 1] divided by 365).

  • SAE Rates by System Organ Class (SOC) During the Study [ Time Frame: Approximately up to 13 years ]
    SAE rates by SOC adjusting for participant-years on study drug anytime post Baseline are summarized, which included the follow up visits. Only treatmentemergent SAEs are summarized. The Baseline is defined as the last available value prior to belimumab start date, for participants treated with placebo in the parent study and last pretreatment value in the parent study for participants treated with belimumab in the parent study. The event rate of an SAE was calculated as the number of events per 100 participant years: Event Rate=100* number of events divided by participant years. Participant years were calculated as sum across all participants ([last visit of interval day minus first visit of interval day plus 1] divided by 365).
