CLINICAL RATIONALE
Transthyretin amyloid cardiomyopathy is a disease characterized by the accumulation of amyloid fibrils composed of misfolded transthyretin protein in the heart. Misfolded monomers or oligomers of transthyretin are deposited in the myocardium, leading to cardiomyopathy and symptoms of heart failure. Infiltration of the conduction system can lead to bundle-branch block, atrioventricular block, sinoatrial disease, and atrial fibrillation. Transthyretin amyloid cardiomyopathy is a late-onset disease; symptoms are predominately manifested in male patients 60 years of age or older. The condition can be inherited as an autosomal dominant trait caused by pathogenic mutations in the transthyretin gene TTR (ATTRm) or by the deposition of wild-type transthyretin protein (ATTRwt). There are more than 120 pathogenic mutations in TTR that result in a variable phenotypic presentation. The prevalence of ATTRwt is uncertain, some studies have reported a prevalence of 13% among patients with heart failure with a preserved ejection fraction, 16% among patients undergoing transcatheter aortic-valve replacement for severe aortic stenosis, and 5% among patients with presumed hypertrophic cardiomyopathy. Treatments have previously been limited to supportive care. Median survival in untreated patients is reported to be 2.5 years after diagnosis for ATTRm caused by the TTR Val122Ile mutation and 3.6 years for ATTRwt. Death in most patients is from cardiac causes, including sudden death and heart failure.2 Diagnosis of cardiac amyloidosis (CA) is performed through radionuclide bone scintigraphy with technetium-labeled bisphosphonates or cardiac biopsy.3,4
Tafamidis is a selective stabilizer of TTR. Tafamidis binds to TTR at the thyroxine binding sites, stabilizing the tetramer and slowing dissociation into monomers, the rate-limiting step in the amyloidogenic process. Efficacy was demonstrated in a multicenter, international, randomized, double-blind, placebo-controlled study in 441 patients with wild type or hereditary ATTR-CM. Patients were randomized in a 1:2:2 ration to receive Vyndaqel 20 mg, Vyndaqel 80 mg, or placebo once daily for 30 months, in addition to standard of care (e.g. diuretics). Treatment assignment was stratified by the presence or absence of a variant TTR genotype as well as baseline disease severity (NYHA Class). The primary analysis points were all-cause mortality and frequency of cardiovascular-related hospitalizations. The analysis demonstrated a significant reduction in all-cause mortality and frequency of cardiovascular-related hospitalizations in the pooled Vyndaqel group.1
