Brief summary
The purpose of this prospective, observational cohort study is to evaluate the incidence of adverse events of special interest (AESI) and effectiveness in participants with active, autoantibody-positive SLE treated with and without BENLYSTA (belimumab). Participants will be enrolled into 1 of 2 cohorts: (1) BENLYSTA cohort: participants receiving or initiating BENLYSTA plus standard of care (SOC) at Baseline; (2) comparison cohort: participants not receiving BENLYSTA but receiving SOC at Baseline. After enrollment, changes in lupus medications, including starting or stopping BENLYSTA, are at the discretion of the physician, and all participants will continue to be followed regardless of changes in their lupus medicines until study completion. All participants will be assessed for AESI including serious infections, opportunistic infections and other infections of interest, malignancies, selected serious psychiatric events and mortality. Data will be collected at enrollment and at 6 month intervals for 5 years. BENLYSTA is a registered trademark of GlaxoSmithKline (GSK) group of companies.
Interventions
As prescribed. Belimumab is a recombinant, human, IgG1λ monoclonal antibody for the treatment of systemic lupus erythematosus.
As prescribed. At baseline, SoC therapy must have included an immunosuppressant. During the registry, SoC therapy could include any of the following (alone or in combination): immunosuppressants, corticosteroids, antimalarials, other biologics, investigational agents for SLE, as clinically indicated.

| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events of Special Interest (AESI) Using Initial Exposure Intent-to-Treat (ITT) Strategy | Up to 63 Months | An adverse event (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. AESIs included mortality, malignancies (excluding non-melanoma skin cancers \[NMSC\]), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events. Initial exposure ITT strategy assigned exposure status of participants based on SLE medication (Benlysta or Non-Benlysta) at enrollment (Day 0). This exposure strategy analyzed all accrued AESI data during the whole follow-up period irrespective of treatment switching from Benlysta to Non-Benlysta or vice-versa. |
| Incidence Rate of AESI Up to 12 Months Using As-Exposed - Time Varying Strategy | Up to 12 Months | 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. AESIs including mortality, malignancies (excluding NMSC), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events were summarized. As-exposed (time varying) exposure strategy dynamically assigned participants' exposure group based on Benlysta/Non-Benlysta use at time of event, during study follow-up. Hence, a participant's exposure group could change over time depending on the SLE medication in use at specific time during study follow-up. For Benlysta, a 14-week risk window was applied wherein exposure ended 14 weeks after Benlysta stopped. Incidence rate is calculated as: Number of first events divided by (/) Total participant-years at risk of event expressed per 100 participant-years. |
| Incidence Rate of AESI Up to 24 Months Using As-Exposed - Time Varying Strategy | Up to 24 Months | 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. AESIs including mortality, malignancies (excluding NMSC), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events were summarized. As-exposed (time varying) exposure strategy dynamically assigned participants' exposure group based on Benlysta/Non-Benlysta use at time of event, during study follow-up. Hence, a participant's exposure group could change over time depending on the SLE medication in use at specific time during study follow-up. For Benlysta, a 14-week risk window was applied wherein exposure ended 14 weeks after Benlysta stopped. Incidence rate is calculated as: Number of first events / Total participant-years at risk of event expressed per 100 participant-years. |
| Incidence Rate of AESI Up to 36 Months Using As-Exposed - Time Varying Strategy | Up to 36 Months | 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. AESIs including mortality, malignancies (excluding NMSC), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events were summarized. As-exposed (time varying) exposure strategy dynamically assigned participants' exposure group based on Benlysta/Non-Benlysta use at time of event, during study follow-up. Hence, a participant's exposure group could change over time depending on the SLE medication in use at specific time during study follow-up. For Benlysta, a 14-week risk window was applied wherein exposure ended 14 weeks after Benlysta stopped. Incidence rate is calculated as: Number of first events / Total participant-years at risk of event expressed per 100 participant-years. |
| Incidence Rate of AESI Up to 48 Months Using As-Exposed - Time Varying Strategy | Up to 48 Months | 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. AESIs including mortality, malignancies (excluding NMSC), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events were summarized. As-exposed (time varying) exposure strategy dynamically assigned participants' exposure group based on Benlysta/Non-Benlysta use at time of event, during study follow-up.

| Event Rate of AESI Up to 12 Months Using As-Exposed - Time Varying Strategy | Up to 12 Months | An AE is any unfavorable or unintended sign, symptom, or disease that is temporally associated with use of study agent but is not necessarily caused by study agent. AESIs including malignancies (excluding NMSC), serious infections, opportunistic infections and other infections of interest, NMSC, and selected serious psychiatric events were summarized. As event rate was computed for potentially recurrent events, no event rate was computed for mortality. As-exposed (time varying) exposure strategy dynamically assigned participants' exposure group based on Benlysta/Non-Benlysta use at time of event, during study follow-up. So, a participant's exposure group could change over time depending on SLE medication in use at specific time during study follow-up. For Benlysta, 14-week risk window was applied wherein exposure ended 14 weeks after Benlysta stopped. Event rate is calculated as: Number of all events / Total participant-years at risk of event expressed per 100 participant-years. |
