Subclinical Transthyretin Cardiac Amyloidosis in V122I TTR Carriers
Approximately 1.5 million of the 44 million Blacks in the United States are carriers of the valine-to-isoleucine substitution at position 122 (V122I) in the transthyretin (TTR) protein. Virtually exclusive to Blacks, this is the most common cause of hereditary cardiac amyloidosis (hATTR-CA) worldwide. hATTR-CA leads to worsening heart failure (HF) and premature death. Fortunately, new therapies that stabilize TTR improve morbidity and mortality in hATTR-CA, especially when prescribed early in the disease. However, hATTR-CA is often diagnosed at an advanced stage and conventional diagnostic tools lack diagnostic specificity to detect early disease. The overall objectives of this study are to determine the presence of subclinical hATTR-CA and to identify biomarkers that indicate amyloid progression in V122I TTR carriers. The central hypothesis of this proposal is that hATTR-CA has a long latency period that will be detected through subclinical amyloidosis imaging and biomarker phenotyping. The central hypothesis will be tested by pursuing 2 specific aims: Aim 1) determine the association of V122I TTR carrier status with CMRI evidence of amyloid infiltration; Sub-aim 1) determine the association of V122I TTR carrier status with cardiac reserve; Aim 2) determine the association between amyloid-specific biomarkers and V122I TTR carrier status; and Sub-aim 2) determine the association of amyloid-specific biomarkers with imaging-based parameters and evaluate their diagnostic utility for identifying subclinical hATTR-CA. In Aim 1, CMRI will be used to compare metrics associated with cardiac amyloid infiltration between a cohort of V122I TTR carriers without HF formed by cascade genetic testing and age-, sex-, and race-matched non-carrier controls. For Sub-Aim 1, a sub-sample of carriers and non-carrier controls enrolled in Aim 1 will undergo novel exercise CMRI to measure and compare cardiac systolic and diastolic reserve. Aim 2 involves measuring and comparing amyloid-specific biomarkers in V122I TTR carriers without HF with samples matched non-carriers (both from Aim 1) and individuals with symptomatic V122I hATTR-CA from our clinical sites. These biomarkers detect and quantify different processes of TTR amyloidogenesis and include circulating TTR, retinol binding protein 4, TTR kinetic stability, and misfolded TTR oligomers. Sub-aim 2 will establish the role of these biomarkers to detect imaging evidence of subclinical hATTR-CA disease.

Safety, Efficacy, and Pharmacokinetics of Tafamidis in Patients With Transthyretin-mediated Amyloidosis Post Orthotopic Heart Transplantation
Transthyretin cardiac amyloidosis (ATTR-CA) is a relentlessly progressive disease that can progress to end stage heart failure, at which point recently approved transthyretin production silencing or structure stabilizing therapies provide no clinical benefit. For well-selected individuals, heart transplantation is an excellent therapeutic option to improve survival. Historically, concomitant liver transplantation has been used to halt the progression of non-cardiac transthyretin amyloidosis (ATTR) manifestations, especially for individuals with TTR genotypes associated with significant neuropathy. However, despite this, patients continue to experience progressive non-cardiac manifestations, particularly gastrointestinal and neuropathic, which can have a substantial influence on post-heart transplantation morbidity. Concomitant liver transplantation is also associated with substantial morbidity and its future therapeutic role is questionable with recently established therapies for ATTR. Therefore, there is a clear unmet need to determine the utility and safety of ATTR targeted therapies for patients with recent heart transplantation for end-stage ATTR-CA. The central hypothesis of this proposal is that in patients who have received a heart transplantation for end-stage ATTR-CA, tafamidis therapy will be efficacious and well-tolerated. We aim to determine the safety and efficacy of tafamidis in stable patients who have undergone heart or combined heart/liver transplantation for ATTR (wild-type or variant) cardiac amyloidosis. The proposed study will be a single-arm intervention clinical trial with tafamidis. Because of the efficacy of tafamidis for both variant ATTR-CA and wild-type ATTR-CA, there is no clinical equipoise for an inactive-comparator placebo arm. The primary endpoint of this study will be serial change in plasma transthyretin (TTR) levels from baseline to 12 months at 3-month intervals. The secondary endpoints of this study will include serial changes in neuropathy assessments, modified body mass indices, incident transplant-specific adverse events, and pharmacokinetics of tafamidis. Observations from this study will establish the role of tafamidis use for the management of ATTR in patients after transplantation for end-stage ATTR-CA.
