A Non-Interventional Multi-Country Post-Authorisation Safety Study (PASS) to Assess the Incidence of Serious Infections & Malignancies in Systemic Lupus Erythematosus (SLE) Patients Exposed to Anifrolumab
This is an observational study, in which the main research question is to evaluate the risk of malignancies and serious infections among moderate/severe SLE patients who receive anifrolumab compared with a comparable population of moderate/severe SLE patients on standard of care who do not initiate anifrolumab.
• First prescription of anifrolumab in the study period (no anifrolumab prescription prior to index date): date of first anifrolumab prescription will be the index date
• A minimum data availability of 12 months prior to index date
• Age ≥18 years at index date
• SLE severity: patients with moderate to severe SLE at index date
• SLE activity: patients with at least a flare (uncontrolled SLE) in the 6 months prior to index date
