Prospective Registry Investigating Maternal and Infant Outcomes in Anifrolumab Users

Purpose

PRIMULA Preg (Prospective Registry Investigating Maternal and Infant Outcomes in Anifrolumab Users) is a prospective, observational cohort study designed to evaluate the association between anifrolumab exposure during pregnancy and subsequent adverse maternal, fetal, and infant outcomes. This study will fulfil an FDA post-marketing requirement.

  • Drug: Anifrolumab
    Anifrolumab is a human monoclonal antibody that binds to subunit 1 of the type 1 interferon receptor, which was developed based on the evidence supporting the role of type 1 interferon pathway in SLE. Clinical trial evidence from TULIP 1 and TULIP 2 have showed that monthly intravenous administration of anifrolumab led to a higher percentage of patients with a response, assessed with the British Isles Lupus Assessment Group-based Composite Lupus Assessment, compared with patients receiving placebo. Moreover, the phase II MUSE study showed that administration of anifrolumab resulted in substantially reduce disease activity, as measured by the SLE Responder Index, compared to patients receiving placebo. Anifrolumab was approved by the FDA and EMA in July 2021 and February 2022, respectively, for the treatment of adult patients with moderate to severe SLE who are receiving standard therapy.

Detailed Description

PRIMULA Preg (Prospective Registry Investigating Maternal and Infant Outcomes in Anifrolumab Users) is a US-based, prospective, observational cohort study designed to evaluate the association between anifrolumab exposure during pregnancy and subsequent adverse maternal, fetal, and infant outcomes. The objective of the pregnancy registry is to compare adverse maternal, fetal, and infant outcomes of pregnant individuals with moderate/severe systemic lupus erythematosus (SLE) who are exposed to anifrolumab during pregnancy with outcomes in an internal comparison cohort of pregnant individuals with moderate/severe SLE who are not exposed to anifrolumab during pregnancy. Participation in the registry is voluntary and participants can withdraw their consent to participate at any time. The study is strictly observational; the schedule of office visits and all treatment regimens will be determined by HCPs. Only data that are documented in patients' medical records during medical care will be actively collected. No additional laboratory tests or HCP assessments will be required as part of this registry. This study will fulfil an FDA post-marketing requirement.
