Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include currently or recently pregnant individuals diagnosed with systemic lupus erythematosus who have either been exposed to anifrolumab or other treatments for moderate/severe SLE.
✕Probably not a fit
Patients who have experienced pregnancy outcomes prior to enrollment or those exposed to known teratogens during pregnancy may not benefit from this study.

What this trial studies
PRIMULA Preg is a prospective, observational cohort study aimed at evaluating the effects of anifrolumab exposure during pregnancy on maternal, fetal, and infant outcomes. The study compares outcomes in pregnant individuals with systemic lupus erythematosus (SLE) who have been exposed to anifrolumab to those who have not. Participation is voluntary, and data will be collected from medical records without requiring additional tests or assessments. This registry is part of an FDA post-marketing requirement.
Why it matters
Potential benefit: If successful, this study could provide critical insights into the safety of anifrolumab for pregnant individuals with SLE and inform treatment decisions.
How similar studies have gone: While this study addresses a specific post-marketing requirement, similar observational studies have shown success in evaluating treatment safety during pregnancy.
