Details and patient eligibility


This study is testing a potential new medicine, NNC6019-0001, for people who have a heart disease due to TTR amyloidosis.The study will look at if this medicine can reduce the symptoms of a heart disease due to TTR amyloidosis, such as heart failure. Participants will either get NNC6019-0001 (apotential new medicine) or placebo (a medicine which has no effect on the body). Which treatment participants get is decided by chance. The chance of getting NNC6019-0001 is two times higher than getting placebo. NNC6019-0001 is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe yet. Participants will get an infusion of the study medicine 13 times, once every 4 weeks. The study will last for about 64 weeks after the first dose of medicine. Participants cannot participate in this study if they have a heart disease other than a heart disease due to TTR amyloidosis.

Inclusion criteria

* Male or female. * Age greater than or equal to (\>=) 18 to less than (\<) 85 years at the time of signing informed consent. * Have an established diagnosis of Transthyretin amyloid cardiomyopathy (ATTR CM) with either wild-type transhyretin (TTR) or hereditary transthyretin (TTR) genotype as per local standards. * Expected to be on stable doses of cardiovascular medical therapy 6 weeks prior to the randomisation visit. * Known end-diastolic interventricular septal wall thickness greater than or equal to (\>=) 12 millimeters (mm). * Presently classified as New York Heart Association (NYHA) Class II-III. * N-terminal-pro brain natriuretic peptide (NT-proBNP) concentration greater than or equal to (\>=) 650 picograms per milliliter (pg/mL) in sinus cardiac rhythm and greater than (\>) 1000 pg/mL in atrial fibrillation at screening. * Completed greater than or equal to (\>=) 150 meters to less than or equal to (\<=) 450 meters on the 6-minute walk test (MWT) at screening. * Estimated glomerular filtration rate (eGFR) greater than or equal to (\>=) 25 milliliter per minute per 1.73 meter square (mL/min/1.73 m\^2) at screening.

Exclusion criteria

* Cardiomyopathy not primarily caused by transthyretin amyloid cardiomyopathy transthyretin amyloid cardiomyopathy (ATTR CM), for example, cardiomyopathy due to hypertension, valvular heart disease, or ischemic heart disease. * A prior solid organ transplant. * Planned solid organ transplant during the study. * Presence or history of malignant neoplasm (other than basal or squamous cell skin cancer, insitu carcinomas of the cervix, or in-situ/high grade prostatic intraepithelial neoplasia (PIN) or low-grade prostate cancer) within 5 years before screening. * Current treatment with calcium channel blockers with conduction system effects (example \[e.g.\], verapamil, diltiazem). The use of dihydropyridine calcium channel blockers is allowed. The use of digoxin will only be allowed if required for management of atrial fibrillation with rapid ventricular response. * Acute coronary syndrome, unstable angina, stroke, transient ischemic attack (TIA), coronary revascularization, cardiac valve repair, or major surgery within 3 months of screening. * Body weight \>120 kilogram (kg) (264.6 pounds \[lb\]) at screening. * History of contrast allergy or adverse reactions to gadolinium-containing agents.
