What this study is about
The goal of this observational registry is to evaluate the safety and outcomes of pregnancy and lactation in women with Fabry disease who are exposed to pegunigalsidase alfa within 30 days prior to conception and/or during pregnancy and lactation. The main objectives are to: * Assess pregnancy outcomes, including maternal and infant health.
View original scientific description
The goal of this observational registry is to evaluate the safety and outcomes of pregnancy and lactation in women with Fabry disease who are exposed to pegunigalsidase alfa within 30 days prior to conception and/or during pregnancy and lactation. The main objectives are to: * Assess pregnancy outcomes, including maternal and infant health. * Evaluate the occurrence of congenital malformations and other neonatal outcomes. This is a global, decentralized, single-arm, prospective and retrospective registry planned to enroll participants over a 10-year period. Eligible patients may be enrolled by their physician or may self-enroll, where permitted by local regulations. Data will be collected through a secure web-based platform, allowing patients and physicians to enter information via electronic case report forms (eCRFs). Pregnancy and clinical outcomes will be documented throughout pregnancy and up to 12 months post-birth. Data from self-enrolled patients will be confirmed by their primary care or attending physician. This registry is observational and does not impact clinical care or treatment decisions.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
