Review of Transthyretin Silencers, Stabilizers, and Fibril Removal Agents in the Treatment of Transthyretin Cardiac Amyloid

AbstractPurpose of ReviewTo provide a functional review for practicing clinicians on the current and emerging treatment considerations for transthyretin (TTR) cardiac amyloidosis (ATTR-CA).Recent FindingsCurrent treatment considerations are characterized as those silencing TTR translation, stabilizing TTR tetramers, and disrupting amyloid fibril deposition.SummaryHistorically considered a rare disease state, ATTR-CA is increasingly recognized as an important mediator of heart failure morbidity and mortality. The emergence of widely available therapies for ATTR-CA has developed hope for patients where little was previously present. Thus, it is important that all cardiology clinicians have a functional understanding of the disease state and treatment options. This review will discuss agents within each of the above classes with expanded discussion on tafamidis given its favorable efficacy, safety, and availability. ATTR-CA diagnostic considerations are reviewed with regard to the identification of potential tafamidis candidates, and practical economic considerations are also reviewed.
