What is the TEGSEDI-PRG Pregnancy Observational Study

The TEGSEDI-PRG pregnancy observational study was developed by Akcea Therapeutics, Inc. to follow patients who have been exposed to at least one dose of TEGSEDI® (inotersen) during their pregnancy (or patients who became pregnant within 25 weeks of taking TEGSEDI). The purpose of this study is to learn more about the health of pregnant women who are taking or have taken TEGSEDI and the health of their babies.

Pregnant women with the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN), who have not been exposed to TEGSEDI, are also eligible for this observational pregnancy study.

Your participation in this study will help Akcea Therapeutics Inc. to gather more information that could help women in the future and their doctors make more informed decisions.
