• Male and/or female participants 18 to 90 years of age inclusive, at the time of signing the informed consent
• Diagnosis of transthyretin (ATTR) amyloidosis with cardiomyopathy, classified as hereditary ATTR amyloidosis with cardiomyopathy (ATTRv-CM) or wild type cardiomyopathy (ATTRwt-CM).
• Must have a body weight of at least 45 kilograms (kg) at Screening visit
• New York Heart Association (NYHA) Class I-III heart failure
• At least 1 prior hospitalization for heart failure and/or clinical evidence of heart failure.
• Able to complete ≥150 meters on the 6-minute walk test (6-MWT) during the Screening period.
  • Cardiomyopathy Exclusion Criteria (UK only):
• Amyloidosis attributable to non-TTR protein, e.g., amyloid light-chain (AL) amyloidosis

  • Investigational TTR stabilizer (e.g., AG-10)
• Participants with heart failure that in the opinion of the investigator is caused by ischemic heart disease, hypertension, or uncorrected valvular disease and not primarily due to transthyretin amyloid cardiomyopathy.
• Participants with a history of sustained ventricular tachycardia or aborted ventricular fibrillation or with a history of atrioventricular (AV) nodal or sinoatrial (SA) nodal dysfunction for which a pacemaker is indicated but will not be placed. Pacemaker or defibrillator placement, initiation of or change in anti-arrhythmic medication within 28 days prior to study drug administration.
