Official title: Real-World Effectiveness of Belimumab in Patients with Systemic Lupus Erythematosus in the United States
Trial description: The goal of this study is to assess the real-world effectiveness of belimumab, among treatment adherent participants with SLE versus those treated with standard of care in the US. The real-world insight gained would help healthcare decision-makers in differentiating belimumab from other treatment options for SLE.

Inclusion and exclusion criteria
Inclusion criteria:
- Inclusion Criteria : Both cohorts:
- Greater than or equal to 6 months of continuous health plan enrollment prior to the index date (Baseline period)
- Greater than or equal to 24 months of continuous health plan enrollment following the index date (follow-up period)
- Diagnosis of SLE during the Baseline period or on the index date based on: >= 2 outpatient (OP) medical claims in any position; or >= 1 inpatient/emergency department (IP/ED) claim in any position
- Greater than or equal to 18 years of age at the index date. Belimumab Adherer Cohort:
- Evidence of belimumab treatment between 01-Jan- 2012 and 31-Mar-2018 with PDC >=80 percent (%) over the 24-month post-index period.
- The index date will be defined as the date of the first claim (dispensing or administration) for belimumab; participants will be required to only use the belimumab Intravenous (IV) formulation on the index date and during the 24-month post-index period (i.e., participants using the belimumab subcutaneous formulation will be excluded). Belimumab Non-User Cohort:
- Evidence of SOC treatment for SLE between 01-January-2012 and 31-March-2018. The index date will be selected among all SOC treatment initiation date (i.e., among participants first claim for an nonsteroidal anti-inflammatory drugs [NSAID], immunosuppressant, corticosteroid, or antimalarial)
- Greater than or equal to 2 dispensings/treatments of any one of the following standard treatment regimens for SLE, at least 6 months apart over the 24-month post-index period; Corticosteroids, NSAIDs, Antimalarials, and Immunosuppressants. Exclusion Criteria: Both Cohorts:
- Greater than or equal to 1 medical claim with a diagnosis of drug-induced SLE any time prior to or on the index date.
- Greater than or equal to 2 diagnoses of renal conditions during the Baseline period or on the index date. Belimumab Adherer Cohort:
- Greater than or equal to 1 dispensing of belimumab subcutaneous formulation on the index date or during the 24-month post-index period Belimumab Non-User Cohort:
- Greater than or equal to 1 dispensing of belimumab at any time during the treatment identification period (01-Jan-2012 to 31-Mar-2018).
