Safety and Effectiveness of BENLYSTA (Belimumab) in Systemic Lupus Erythematosus (SLE) Registry

Study 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.

Primary Outcome

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 m
