AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with transthyretin amyloidosis (ATTR) with heart disease, who have had heart failure. It compares nucresiran with placebo.

Age
18 to 85 years
Sex
All sexes
Disease stage
ATTR amyloidosis with cardiomyopathy, hereditary or wild-type. History of heart failure with at least 1 hospital stay for it, or symptoms that need a diuretic.
Earlier treatment
Can be taking approved TTR stabilizers (for example tafamidis, acoramidis) and heart failure treatment. Cannot have had, or be getting, TTR-lowering therapy.
Biomarker or test result
NT-proBNP above 300 ng/L and below 8500 ng/L. With permanent or persistent atrial fibrillation: above 600 ng/L and below 8500 ng/L.

Main reasons for not taking part

  • NYHA Class IV heart failure
  • NYHA Class III heart failure together with ATTR Amyloidosis Disease Stage 3
  • Polyneuropathy disability (PND) score IIIa, IIIb, or IV
  • eGFR below 30 mL/min/1.73m^2 at screening
  • Past or current TTR-lowering therapy

TRITON-CM: A Phase 3 Global, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Nucresiran in Patients With Transthyretin-Mediated Amyloidosis With Cardiomyopathy (ATTR Amyloidosis With Cardiomyopathy)

The purpose of this study is to:

* Evaluate the efficacy of nucresiran compared to placebo on reducing all-cause mortality and cardiovascular (CV) events * Evaluate the efficacy of nucresiran compared to placebo on additional assessments of CV events and/or death * Evaluate the efficacy of nucresiran compared to placebo on patient-reported health status and health-related quality of life

Inclusion: Has documented diagnosis of ATTR amyloidosis with cardiomyopathy including those with hereditary ATTR (hATTR) or wild-type ATTR (wATTR) amyloidosis; Has medical history of heart failure (HF) with at least 1 prior hospitalization for HF or signs and symptoms that require treatment with a diuretic; Has screening N-terminal prohormone B-type natriuretic peptide (NT-proBNP) >300 ng/L and <8500 ng/L; In patients with permanent or persistent atrial fibrillation, screening NT-proBNP >600 ng/L and <8500 ng/L; Patients may be receiving approved TTR stabilizers for ATTR amyloidosis (eg, tafamidis, acoramidis) and may be receiving background therapy for HF at the discretion of the Investigator.

Exclusion: Has received prior or currently receiving TTR-lowering therapy; Has New York Heart Association (NYHA) Class IV HF; or NYHA Class III heart failure AND ATTR Amyloidosis Disease Stage 3; Has an estimated glomerular filtration rate (eGFR) of <30 mL/min/1.73m\^2 at screening; Has a polyneuropathy disability (PND) Score IIIa, IIIb, or IV.
