Filter by:The primary objective of this study is to evaluate the diagnostic performance of an algorithm in identifying patients with ATTR amyloidosis.
Specific, standardized, comprehensive, universally accepted Patient-Reported Outcome Measures (PROMs) are currently lacking for variant and wild-type cardiac amyloid transthyretin amyloidosis (v-ATTR/wt-ATTR). Our goal is then to create two scores able to provide a cumulative assessment of cardiac involvement, peripheral neuropathy (in v-ATTR), and comorbidities, and their impact on the quality of life. In the setting of a nationwide collaboration involving 5 main Italian referral centers for this condition (in Ferrara, Florence, Pavia, Pisa and Messina), a panel will be created, including experts of ATTR cardiomyopathy, neurologists, geriatricians, health management specialists, as well as patients with either variant or wild-type ATTR cardiomyopathy (n=50). The most clinically relevant domains for patients (such as physical limitations, symptoms, self-efficacy and knowledge, social interference, quality of life, age-related issues, social and family environment, frailty, comorbidities) will be identified. Two sets of 30 items (one for variant and another for wild-type ATTR cardiomyopathy) will be created in collaboration with patients. Questions will be formatted for gender neutrality, clarity, interpretability, and possible foreign language translations. PROMs scores will be validated through administration to around 250 consecutive outpatients. Score performance will be evaluated in terms of internal consistency, response to clinical changes, comparison with conventional clinical measures. The time needed for completion, the clarity of questions and the need for assistance from a family caregiver will be evaluated. This project will hopefully lead to the identification of disease-specific metrics that may serve as a clinically meaningful outcome in cardiovascular research, patient management, and quality assessment.
The purpose of this study is to: - Describe epidemiological and clinical characteristics, natural history and real-world clinical management of ATTR amyloidosis patients - Characterize the safety and effectiveness of patisiran and vutrisiran as part of routine clinical practice in the real-world clinical setting - Describe disease emergence/progression in pre-symptomatic carriers of a known disease-causing transthyretin (TTR) variant
Introduction: Transthyretin cardiac amyloidosis (ATTR) is an important cause of heart failure. Cardiac planar radionuclide imaging using 99mTc-labeled bone seeking radiopharmaceuticals is used as a noninvasive diagnostic criterion in patients without detectable monoclonal protein. The visual assessment remains the main noninvasive criterion for the diagnosis. Medical therapy using tafamidis meglumine that binds to transthyretin and prevents amyloidogenesis, recently demonstrated a reduction in all-cause mortality and cardiovascular-related hospitalizations. As a consequence, there is a need for quantitative approaches that would be useful for diagnosis and prognosis assessment but also for the evaluation of patient therapeutic response. Materials and methods: The investigators aim to include 35 patients with a suspected diagnosis of cardiac ATTR amyloidosis in whom a cardiac planar radionuclide imaging using 99mTc-labeled bone seeking radiopharmaceuticals is planned as part of routine noninvasive diagnosis work-up. Using a test-retest approach, the aim is to compare a quantitative method vs. conventional semi-quantitative approaches for the assessment of cardiac uptake of bone radiopharmaceuticals using new 3D CZT-based SPECT-CT cameras in patients with suspected cardiac ATTR amyloidosis. The investigators estimated that 20 patients will have a diagnosis of cardiac ATTR amyloidosis. In the latter patients, the aim is to evaluate the impact of 6-month therapy using tafamidis on quantitative and semi-quantitative assessment of cardiac uptake of bone radiopharmaceuticals Perspectives: This new non invasive imaging techniques for the quantitative assessment of the amyloid burden in patients with cardiac ATTR amyloidosis may help identify the responders and the patients who should benefit from dose intensification.
The study will investigate the stabilization effects of Tafamidis utilizing cardiac imaging cardiac magnetic resonance imaging (CMR). The investigators propose to pursue the following specific aims: 1. Utilize cardiac magnetic resonance to assess stabilization of ATTR after Tafamidis therapy based on extracellular volume mapping. 2. Investigate left ventricular myocardial mass, native T1, T2, and extracellular volume mapping after 12 month follow-up. 3. Utilize cardiac magnetic resonance feature tracking at baseline and at 12 month follow-up.
AL (or light chain) amyloidosis begins in the bone marrow where abnormal proteins misfold and create free light chains that cannot be broken down. These free light chains bind together to form amyloid fibrils that build up in the extracellular space of organs, affecting the kidneys, heart, liver, spleen, nervous system and digestive tract. The primary purpose of this study is to determine whether CAEL-101, a monoclonal antibody that removes AL amyloid deposits from tissues and organs, improves overall survival and it is safe and well tolerated in patients with stage IIIa AL amyloidosis.

Patients with light chain (AL) amyloidosis who have advanced cardiac damage are at risk of premature mortality. There is ongoing unmet need for effective therapies to rapidly induce deep hematologic response and decrease the early death rate. Lately, trials of daratumumab in newly-diagnosed and relapsed/refractory AL amyloidosis have shown dramatic response rates. However, the benefits of upfront daratumumab in stage III AL patients, especially stage IIIb patients, have not yet been demonstrated definitely in prospective studies. Therefore, we designed a phase II, single arm clinical trial to investigate the efficacy and safety of co-administration of daratumumab with bortezomib and dexamethasone (BD) regimen in treatment-naïve patients with Mayo 04 stage III AL amyloidosis. We planned to enroll 40 patients, who would receive daratumumab and BD treatment for a total duration of 12 months. The primary endpoint is complete response and very good partial response at 3 months after treatment initiation. Secondary endpoints include overall survival, organ response and adverse events.
The primary purpose of this study is to determine whether treatment with lecanemab is superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether treatment with lecanemab is superior to placebo in reducing brain amyloid accumulation as measured by amyloid positron emission tomography (PET) at 216 weeks of treatment (A3 Trial). This study will also evaluate the long-term safety and tolerability of lecanemab in participants enrolled in the Extension Phase.
Cardiac amyloidosis is an increasingly contributor of degenerative cardiac diseases. However, its frequency remains underestimated, and diagnosis is often realized at late stages of the disease. A larger use of clinical and echographic Red Flag signals during routine echocardiographic examination may enhance the identification of early stage of the disease.
