NatiOnal Referral cenTEr Study of Transthyretin Amyloid Cardiomyopathy(ATTR) Patients on Tafamidis (NOTE-ATTR)

April 13, 2026 updated by: Paolo Milani

NatiOnal Referral cenTEr Study of Transthyretin Amyloid Cardiomyopathy(ATTR) Patients on Tafamidis: Real World Prospective Study

All ATTRwt patients on tafamidis 61 mg treatment will be clinically evaluated before treatment initiation and subsequently every six months for the eligibility to continue tafamidis treatment, according to Italian Medicines Agency regulations. C onsidering the significant risk of developing heart rhythm disturbances due to cardiac amyloidosis, especially in transthyretin form (ATTRwt), in routine clinical practice a stricter heart rhythm monitoring is recommended in ATTRwt patients. Moreover, particular attention is usually paid for those who present atrio-ventricular and/or intraventricular block at the baseline electrocardiogram. Data about rhythm disturbances and diuretic dose need will be collected during the planned physical examination every six months and the Holter ECG monitoring requested by the physician at the end of every planned clinical evaluation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All patients with a diagnosis of ATTRwt disease and eligible for tafamidis treatment according to the national drug regulatory agency criteria and no prior history of atrial trachy-arrhythmia and/or bradyarrhythmias in their past medical history will undergo screening procedure to be enrolled in the present study.

Description

Inclusion Criteria:

  • Diagnosis of ATTRwt amyloidosis.
  • 18 years or older;
  • evidence of cardiac involvement at echocardiography or cardiac MRI.
  • No known prior history of atrial fibrillation or major bradyarrhythmia (second degree atrioventricular block, third-degree atrioventricular block, high-grade atrioventricular block or alternating right and left branch block)
  • female patients who are postmenopausal for at least 1 year before the screening visit
  • patients on therapy or candidates for therapy with tafamidis 61 mg
  • voluntary written consent must be given before performance of any study-related procedure not part of standard medical care with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

Exclusion Criteria:

  • Non-ATTR amyloidosis;
  • NYHA class III and IV;
  • Pregnant or nursing women;
  • Previous pacemaker implantation;
  • any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with a fully comprehension of the written consent form

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cumulative incidence of atrial tachy-arrhythmia and brady-arrhythmias requiring pacemaker and/or defibrillator
Time Frame: 18 months
All ATTRwt patients eligible for tafamidis with no prior history of atrial tachy-arrhythmia or brady-arrhythmias will be prospectively enrolled. The events (arrythmias incidence) will be collected by the usually rhythm monitoring that physician will recommend at the end of clinical evaluation according to clinical practice
18 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
patient diuretic dose need (i.e. Furosemide), reported as mg/Kg/die
Time Frame: 18 months
18 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 26, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
January 26, 2027

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
