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.
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.

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.

RECRUITINGComposite 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.
Time frame: From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births
Composite outcome of all minor congenital malformations
An anomaly or abnormality of body structure that is present at birth, is of prenatal origin (i.e., birth defect), poses no significant health problem in the neonatal period, and tends to have limited social or cosmetic consequences for the affected individual. Relevant exposure window includes any trimester of pregnancy.
Time frame: From date of conception (DOC) to pregnancy outcome for fetal losses or 12 months of infant age for live births
Worsening of underlying disease
Any increase in disease activity or severity in the pregnancy period compared to the baseline period (6 months prior to pregnancy) as assessed by the disease flare or disease activity algorithms or as reported by an HCP. Relevant exposure window includes any trimester of pregnancy.
Time frame: From date of conception (DOC) to pregnancy outcome, up to 42 weeks of pregnancy
Premature rupture of membranes
A disorder of pregnancy defined as rupture of membranes before the onset of labor. Relevant exposure window includes any trimester of pregnancy.
Time frame: From date of conception (DOC) to pregnancy outcome, up to 42 weeks of pregnancy
Pregnancy-induced hypertension
A disorder of pregnancy defined as a systolic blood pressure 140 mmHg or more or a diastolic blood pressure of 90 mmHg or more, or both, on 2 occasions at least 4 hours apart after 20 weeks gestation, in a woman with a previously normal blood pressure.

Composite outcome of preeclampsia/eclampsia
Preeclampsia is a disorder of pregnancy associated with new-onset hypertension, which occurs most often after 20 weeks of gestation and frequently near term, and proteinuria. Or, in the absence of proteinuria, it is defined as new-onset hypertension with the new onset of any of the following: * Thrombocytopenia: platelet count less \<100 ,000/mL * Renal insufficiency: serum creatinine concentrations \>1.1mg/dL or a doubling of the serum creatinine concentration in the absence of other renal disease * Impaired liver function: elevated blood concentrations of liver transaminases to twice normal concentration * Pulmonary edema * New-onset headache unresponsive to medication and not accounted for by alternative diagnoses or visual symptoms. Eclampsia is new-onset tonic-clonic, focal, or multifocal seizures in the absence of other causative conditions such as epilepsy, cerebral arterial ischemia and infarction, intracranial hemorrhage, or drug use.
Time frame: From 20 gestational weeks to pregnancy outcome, up to 42 weeks of pregnancy
Maternal hospitalization for serious illness

Time frame: From date of conception (DOC) to pregnancy outcome, up to 42 weeks of pregnancy
Spontaneous abortion
An involuntary fetal loss or the expulsion of the products of conception occurring at \<20 gestational weeks.
Time frame: From date of conception (DOC) to <20 gestational weeks
Elective termination
An intervention that is intended to terminate a suspected or known ongoing intrauterine pregnancy and that does not result in a live birth. Relevant exposure window includes any trimester of pregnancy.
