Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Composite outcome of all major congenital malformations (MCMs)

    An abnormality of body structure or function that is present at birth, is of prenatal origin (i.e., birth defect), has significant medical, social, or cosmetic consequences for the affected individual, and typically requires medical intervention. Relevant exposure window is limited to 1st trimester of pregnancy.

    From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births

Secondary Outcomes (15)

  • Composite outcome of all minor congenital malformations

    From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births

  • Worsening of underlying disease

    From date of conception (DOC) to pregnancy outcome, up to 42 weeks of pregnancy

  • Premature rupture of membranes

    From date of conception (DOC) to pregnancy outcome, up to 42 weeks of pregnancy

  • Pregnancy-induced hypertension

    From 20 gestational weeks to pregnancy outcome, up to 42 weeks of pregnancy

  • Composite outcome of preeclampsia/eclampsia

    From 20 gestational weeks to pregnancy outcome, up to 42 weeks of pregnancy

  • +10 more secondary outcomes

Study Arms (2)

Exposed cohort

Pregnant individuals with a diagnosis of moderate/severe SLE who are exposed to anifrolumab at any time during pregnancy

Drug: Anifrolumab

Unexposed cohort

Pregnant individuals with a diagnosis of moderate/severe SLE who are not exposed to anifrolumab at any time during pregnancy but who are exposed to other products for the treatment of SLE

Interventions

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.

Study Population

The study population will include 2 cohorts of pregnant individuals: a cohort of individuals with moderate/severe SLE who are exposed to anifrolumab and a cohort of individuals with moderate/severe SLE who are unexposed to anifrolumab but who are exposed to other products for the treatment of SLE.

You may qualify if:

  • Exposed cohort
  • Currently or recently (within 1 year of pregnancy outcome) pregnant
  • Diagnosis of moderate/severe SLE
  • Consent to participate

  • Currently or recently pregnant
  • Diagnosis of moderate/severe SLE
  • Consent to participate
  • Authorization for their HCP(s) to provide data to the registry
  • Exposure to other products for the treatment of moderate/severe SLE

You may not qualify if:

  • Exposure to known teratogens and/or investigational medications during pregnancy
  • Unexposed cohort
