Pregnancy and postpartum outcomes after pegunigalsidase alfa exposure in women with Fabry disease
Official title: Maternal and Postnatal Outcomes Study (MOS) A Worldwide Decentralized Observational Registry to Evaluate the Safety in Women With Fabry Disease and Their Infants Exposed to Elfabrio® (Pegunigalsidase Alfa-iwxj/Pegunigalsidase Alfa) During Pregnancy and/or Lactation
Run by Chiesi Farmaceutici S.p.A. · NCT06941025 · Data updated 2026-11-12
This registry will collect information to see how pregnancies and babies do when women with Fabry disease received pegunigalsidase alfa shortly before conception, during pregnancy, or while breastfeeding.

Is this trial a fit for you?
✓Likely a good fit
Women with Fabry disease who received at least one dose of pegunigalsidase alfa within 30 days before conception or at any time during pregnancy or lactation, and their infants, who can provide consent or have a legal representative, are ideal candidates.
✕Probably not a fit
Patients who were not exposed to pegunigalsidase alfa, whose exposure fell outside the defined window, who cannot provide consent, or who cannot complete follow-up are unlikely to gain useful data from this registry.

What this trial studies
This global, decentralized registry will collect both retrospective and prospective data on pregnancies and infant health when mothers with Fabry disease were exposed to pegunigalsidase alfa within 30 days prior to conception or during pregnancy or lactation. Enrollment is planned over a 10-year period and participants may be entered by their clinician or may self-enroll where local regulations permit, with data entered through a secure web-based platform and electronic case report forms. Pregnancy outcomes, delivery details, reported congenital malformations (adjudicated by an independent Scientific Advisory Committee), and infant health up to 12 months of age will be documented. The registry is observational, does not dictate treatment, and collects real-world safety and outcome data without exclusion criteria beyond exposure and ability to consent.
Why it matters
Potential benefit: If successful, the registry could provide clearer safety information to help clinicians and pregnant women with Fabry disease make informed treatment decisions about pegunigalsidase alfa during pregnancy and breastfeeding.
How similar studies have gone: Pregnancy registries for enzyme replacement therapies in other lysosomal storage disorders have generated useful safety signals, but published data specifically on pegunigalsidase alfa in pregnancy are limited.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Female patients with Fabry disease who have been exposed to at least 1 dose of pegunigalsidase alfa at any time during pregnancy (defined as having received pegunigalsidase alfa within 30 days prior to the DOC and/or during pregnancy) and/or during lactation, and their infants. o DOC, defined as 20/7 gestational weeks, will be calculated from last menstrual period \[LMP\] or ultrasound * Patient or parent/legally authorized representative must be able to understand and provide consent through an Institutional Review Board / Independent Ethics Committee (IRB/IEC) approved Informed Consent Form. Exclusion Criteria: * None
