Descriptive Information
Brief Title  ICMJE Safety and Efficacy of Tafamidis in Patients With Transthyretin Cardiomyopathy
Official Title  ICMJE A MULTICENTER, INTERNATIONAL, PHASE 3, DOUBLE-BLIND, PLACEBO-CONTROLLED, RANDOMIZED STUDY TO EVALUATE THE EFFICACY, SAFETY, AND TOLERABILITY OF DAILY ORAL DOSING OF TAFAMIDIS MEGLUMINE (PF-06291826) 20 MG OR 80 MG IN COMPARISON TO PLACEBO IN SUBJECTS DIAGNOSED WITH TRANSTHYRETIN CARDIOMYOPATHY (TTR-CM)
Brief Summary This Phase 3 study will investigate the efficacy, safety and tolerability of an oral daily dose of 20 mg or 80 mg tafamidis meglumine capsules compared to placebo in subjects with either transthyretin genetic variants or wild-type transthyretin resulting in amyloid cardiomyopathy.
