What this trial studies

This is an observational registry collecting both prospective and retrospective data on people with hypoparathyroidism who were exposed to YORVIPATH during pregnancy or within the 15 days before conception. Data will include pregnancy and maternal complications, fetal and neonatal outcomes, and infant follow-up through at least the first year of life, using medical records and participant-provided information. Participants must provide consent (or assent with guardian consent for minors) and a medical release of information to allow data collection. The registry is sponsored by Ascendis Pharma and lists enrollment through the Ascendis Investigational Site in Morgantown, West Virginia.

Who should consider this trial

Good fit: Ideal candidates are people aged 15–50 with hypoparathyroidism who received at least one dose of YORVIPATH within 15 days before conception or at any time during pregnancy and who can provide consent and a medical release.

Not a fit: People who were not exposed to YORVIPATH during the specified window or pregnancies where only the male partner was exposed are not eligible and would not benefit from this registry's findings.

Why it matters

Potential benefit: If successful, the registry could provide clearer safety information to help pregnant people and clinicians make informed treatment and counseling decisions about YORVIPATH use.

How similar studies have performed: Pregnancy registries for other medications have helped identify safety signals and guide counseling, but pregnancy-specific data for YORVIPATH are novel and limited.
