Transthyretin Amyloid Cardiomyopathy Clinical Trial
An Extension Study to Assess Long-Term Safety of Eplontersen in Adults With Transthyretin-Mediated Amyloid Cardiomyopathy (ATTR-CM)
The purpose of this study is to evaluate the safety and tolerability of extended dosing with eplontersen in participants with ATTR-CM.
This is a multicenter, open-label, Phase 3 study in up to approximately 1400 participants. Eligible participants will receive eplontersen once every 4 weeks for up to 36 months or 6 months after eplontersen is approved and available in the site's country, whichever occurs first. Participants will also receive daily supplemental doses of the recommended daily allowance (RDA) of vitamin A. This study will consist of the following periods: less than or equal to (≤) 10-week screening assessment period, up to 36-month treatment period, and up to 6-month post-treatment evaluation period.
Satisfactory completion of Treatment Period and the End of Treatment Visit of the Index Study (ION-682884-CS2) OR diagnosis of ATTR-CM and satisfactory participation on ISIS 420915- CS101 study as judged by the Investigator and Sponsor.
Investigator is willing to treat the participant with open-label eplontersen.
Willingness to adhere to vitamin A supplementation per protocol.
Permanently discontinued study drug administration while participating in the Index Study (ION 682884-CS2) or IST (ISIS 420915-CS101 Study).
