What this trial studies

The PRIM program is a supplemental pharmacovigilance effort that gathers enhanced secondary data on pregnancies exposed to anifrolumab reported to AstraZeneca's safety database. Initial pregnancy reports are captured from patients or healthcare providers and are followed up near delivery and again at 12 months postpartum to collect infant outcomes. Retrospective reports with completed outcomes are also included, and data are mapped to pre-specified analytic variables using targeted follow-up checklists and guidance. Cases already enrolled in the prospective pregnancy registry or involving known teratogens or investigational drugs are excluded.

Who should consider this trial

Good fit: People who are currently pregnant or recently pregnant (outcome within the past year) who received at least one dose of anifrolumab during pregnancy or within 16 weeks before conception and who are not enrolled in the prospective pregnancy registry are ideal candidates.

Not a fit: People who were not exposed to anifrolumab, who were exposed to known teratogens or investigational medications, or who were already enrolled in the separate prospective pregnancy registry will not benefit from inclusion in this program.

Why it matters

Potential benefit: If successful, this program could improve understanding of anifrolumab safety in pregnancy and help inform treatment decisions for people with lupus.

How similar studies have performed: Pregnancy registries and post-marketing surveillance programs for biologic therapies have previously provided useful safety signals, but data specifically for anifrolumab are limited and this program supplements an existing prospective registry.
