Official title: A Non-Interventional Multi-Database Post-Authorisation Study to Assess Pregnancy-Related Safety Data From Women With SLE Exposed to Anifrolumab

Run by AstraZeneca · NCT07049653 · Data updated 2026-11-12

This study looks at pregnancy outcomes in women with moderate to severe SLE who took anifrolumab during pregnancy and compares them to similar women who did not take the drug.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women with moderate to severe SLE who were exposed to anifrolumab during pregnancy or in the 16-week preconception period and have continuous database enrollment for at least 12 months before LMP.

Probably not a fit

Pregnancies in women with SLE who were not exposed to anifrolumab during pregnancy or who do not meet the exposure criteria may not see information about drug-related pregnancy safety from this study.

What this trial studies

This is a non-interventional, multi-database post-authorisation study designed to describe congenital malformations, adverse pregnancy outcomes, and birth outcomes in pregnancies exposed to anifrolumab. It will compare these outcomes with pregnancies in women with SLE who received standard of care but not anifrolumab, and will also examine infant growth up to one year of age. The analysis relies on real-world data from observational sources to characterize safety signals in this patient group. The study includes women with continuous database enrollment, a diagnosis of SLE before pregnancy, and exposure to anifrolumab during pregnancy or in the 16 weeks prior to the last menstrual period, as well as a comparator group not exposed to the drug.

Why it matters

Potential benefit: If successful, the study could clarify the safety of anifrolumab in pregnancy and inform clinicians and patients on potential risks and outcomes for infant health.

How similar studies have gone: Prior observational safety studies in autoimmune diseases have provided useful signals; this design aims to extend that approach to anifrolumab pregnancy data.
