In the infiltrative cardiomyopathy study, 35 patients with wild-type or Val122Ile TTR amyloidosis with cardiomyopathy also received tafamidis once daily for 12 months, with TTR stabilization at week 6 compared with baseline as the primary end point, and secondary outcome measures, including incidence of treatment-emergent adverse events and change from baseline in echocardiography, cardiac MRI, chest x-ray, and Holter monitoring parameters, NT-proBNP, troponin I and T cardiac biomarkers, 6-minute walk test (6MWT), and health-related QOL measures. This evidence concerns the gene TTR and amyloidosis.
