Official title
A Multicenter, Open-Label, Single Arm, Post-Marketing Clinical Study to Evaluate the Therapeutic Effects of Acoramidis Hydrochlorideon Cardiac Biomarkers and Current Clinical Features in Patients With Transthyretin-type Cardiac Amyloidosis: The CARE ATTR Study
Overview
The purpose of this study is to confirm that the treatment with acoramidis prevents the deterioration of the ATTR-CM disease progression index and that these indexes are surrogate markers of disease progression.
Interventions
- Drug Acoramidis
Participants will receive acoramidis tablets orally.
Primary outcome measures
- Disease Progression Rate as Measured by N-terminal pro-brain-type Natriuretic Peptide (NT-proBNP) and/or Outpatient Diuretic Intensification (ODI) [Time frame: Baseline through 12 months]
Secondary outcome measures (6)
- Disease Progression Rate as Measured by NT-proBNP and/or High-sensitivity Cardiac Troponin T (hs-CTnT) [Time frame: Baseline through 12 months]
- Change from Baseline in Serum Transthyretin (TTR) [Time frame: Baseline, 28 days]
- Number of Participants with a 30% Change from Baseline in NT-proBNP [Time frame: Baseline, 12 months and 18 months]
- Change from Baseline in hs-CTnT [Time frame: Baseline, 12 months and 18 months]
- Change from Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ-12) Overall Summary Score [Time frame: Baseline, 12 months and 18 months]
- Change from Baseline in Estimated Glomerular Filtration Rate (eGFR) [Time frame: Baseline, 12 months and 18 months]
Eligibility criteria
Inclusion criteria
- Treatment history of ATTR-CM is one of the following:
- Naive participants: newly diagnosed with ATTR-CM and no prior treatment with drugs for ATTR-CM
- Switch participants: Participants who are using tafamidis, a TTR stabilizer, as treatment for ATTR-CM and who, in the judgment of the post-marketing clinical trial investigator (co-principal investigator), can be expected to benefit from switching to acoramidis.
- Naive participants must meet the following requirements:
- History of hospitalization for heart failure or heart failure symptoms requiring treatment, including diuretics
- Echocardiographic end-diastolic ventricular septal thickness greater than 12 millimeters (mm)
- Confirmed diagnosis of ATTR-CM (wild type or mutant) by one of the following diagnostic methods
- Tissue biopsy shows amyloid deposition and TTR precursor protein is identified by immunohistochemistry or mass spectrometry.
- Bone scintigraphy showing strong accumulation \*\* (Perugini score ≥ 2) consistent with myocardium and no M protein, negating the possibility of AL amyloidosis
Exclusion criteria
- Have confirmed diagnosis of AL amyloidosis
- Switch participants: prior treatment with gene silencing agents (pachysilane sodium, butrisilane sodium) as treatment for ATTR-CM (including when specifically scheduled to start treatment with a gene silencing agent)
- Likelihood of receiving a heart transplant within 1 year from the time screening begins
- Hypersensitivity to acoramidis, its metabolites, or additives in the formulation has been confirmed.
- Pregnant or lactating women
- Has a clinically significant medical condition, an abnormal laboratory test result, or a condition that may jeopardize the safety of the study participant, increase the risk of participation in the post-marketing clinical trial, or affect the study
- Participating in an interventional study other than this study, including a clinical trial
- In the opinion of the responsible (sub)physician for the post-marketing clinical trial, has a history of drug abuse, alcoholism, or psychiatric disorder that would preclude compliance with this Post-Marketing Clinical Study Protocol
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
