What this trial studies

The INTERSTELLAR study aims to gather real-world evidence on the effectiveness of Anifrolumab when added to standard care for patients with Systemic Lupus Erythematosus (SLE). This multi-country, observational cohort study will collect clinical assessments and patient-reported outcomes over a one-year follow-up period after the initial prescription of Anifrolumab. The study will include a retrospective baseline data collection and will standardize measures across participating countries to facilitate comprehensive analysis. It seeks to inform healthcare providers and patients about the potential benefits of Anifrolumab in treating SLE, particularly its impact on skin manifestations.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been newly prescribed Anifrolumab for their SLE treatment.

Not a fit: Patients currently involved in other clinical trials or those with prior exposure to Anifrolumab may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the real-world effectiveness of Anifrolumab for patients with SLE, potentially improving treatment strategies.

How similar studies have performed: While this study is observational and aims to generate real-world evidence, similar studies have shown promise in evaluating treatment outcomes for autoimmune diseases.
