Acoramidis Transthyretin Amyloidosis Prevention Trial in the Young (ACT-EARLY) Study in Asymptomatic Carriers of a Pathogenic TTR Variant

The AG10-501 ACT-EARLY study is a randomized, multicenter, double-blind, placebo-controlled study of acoramidis for prevention of ATTR (with specific reference to either its cardiomyopathic or polyneuropathic manifestations). Participants will be stratified at randomization. The study population will be asymptomatic carriers of a known pathogenic TTR gene variant. A participant must be 18 to 75 inclusive years of age, and the age of the participant must be within 10 years younger than or older than the predicted age of disease onset (PADO) based either on family history (pedigree analysis) or, if family history is insufficient, based on a TTR Variant Actuarial table from published literature. For example, if PADO for a given individual is found to be 50 years, the age of the participant must be between 40 and 75 years inclusive.
