Primary Outcome Measures

Number of Participants With the Indicated Type of Adverse Event (AEs) and Serious Adverse Event (SAEs)
An AE is defined as any untoward medical occurrence in a participant (par.) temporally associated with the use of a investigational product (IP), whether or not considered related to the IP. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of an IP. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is an important medical event that jeopardizes the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition, or is associated with liver injury and impaired liver function. Only those participants available at the specified time points (represented by n=X, in the category titles) were analyzed.
AE Rates by System Organ Class (SOC) During the Study
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 adverse events (AEs) are summarized. The Baseline is defined as the Year 1 Day 0 values 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 / Participant Years. Participant years were calculated as sum across all participants ([last visit of interval day - first visit of interval day + 1]/365). Participant years excluded between study gaps if participant had not started extension study on date of last visit of parent study.

Primary Outcome Measure Information:
Title
Number of Participants With the Indicated Type of Adverse Event (AEs) and Serious Adverse Event (SAEs)
Description
An AE is defined as any untoward medical occurrence in a participant (par.) temporally associated with the use of a investigational product (IP), whether or not considered related to the IP. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of an IP. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is an important medical event that jeopardizes the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition, or is associated with liver injury and impaired liver function. Only those participants available at the specified time points (represented by n=X, in the category titles) were analyzed.
Time Frame

Title
AE Rates by System Organ Class (SOC) During the Study
Description
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 adverse events (AEs) are summarized. The Baseline is defined as the Year 1 Day 0 values 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 / Participant Years. Participant years were calculated as sum across all participants ([last visit of interval day - first visit of interval day + 1]/365). Participant years excluded between study gaps if participant had not started extension study on date of last visit of parent study.
