What this trial studies

This observational study aims to assess the safety of pregnancy outcomes in women diagnosed with hereditary transthyretin-mediated amyloidosis with polyneuropathy (hATTR-PN). It will compare outcomes between women who have been exposed to the treatment TEGSEDI and those who have not. The study will also evaluate pediatric outcomes for children up to one year of age. Participants will be recruited from a specialized pregnancy coordinating center in Morgantown, West Virginia.

Who should consider this trial

Good fit: Ideal candidates include pregnant women diagnosed with hATTR-PN, either exposed or unexposed to TEGSEDI.

Not a fit: Patients who are not pregnant or do not have a diagnosis of hATTR-PN will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety of TEGSEDI during pregnancy, potentially guiding treatment decisions for affected women.

How similar studies have performed: While there may be limited data on similar studies, this approach is relatively novel in the context of hATTR-PN and pregnancy.
