Primary outcome measure(s)

  • Risk of major congenital malformations (MCM) — From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births
    Describe and estimate the risk of MCM in live and non-live offspring from the women who had moderate/severe SLE and were exposed to anifrolumab during the first trimester of pregnancy or exposed to SOC and unexposed to anifrolumab during the first trimester of pregnancy
  • Relative risk of MCM — From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births
    Estimate the relative risk of MCM in live and non-live offspring from the women who had moderate/severe SLE and were exposed to anifrolumab during the first trimester of pregnancy or exposed to SOC and unexposed to anifrolumab during the first trimester of pregnancy
  • Risk of select pregnancy loss outcomes — At delivery/birth
    Describe and estimate the risk of select pregnancy loss outcomes (composite of spontaneous abortion and stillbirth) in all pregnancies from women who had moderate/severe SLE and were exposed or unexposed to anifrolumab during pregnancy
  • Relative risk of select pregnancy loss outcomes — At delivery/birth
    Estimate the relative risk of select pregnancy loss outcomes (composite of spontaneous abortion and stillbirth) in pregnancies from women who had moderate/severe SLE and were exposed or unexposed to anifrolumab during pregnancy
