Filter by: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.
This study will evaluate the efficacy and safety of vutrisiran 25 mg administered subcutaneously (SC) once every 3 months (q3M) compared to placebo in patients with ATTR amyloidosis with cardiomyopathy.
To evaluate the efficacy of eplontersen compared to placebo in participants with ATTR-CM receiving available standard of care (SoC). For more information, please visit https://www.cardio-ttransform.com.
This is an open-label, multicenter, Phase 2 study in subjects with newly diagnosed stage 3B light chain (AL) amyloidosis.
Severe aortic stenosis is defined with a mean transvalvular pressure gradient (MTPG) > 40mmHg and a calculated aortic valve area of < 1cm2. However, a considerable proportion of patients do have a MTPG < 40mmHg due to a reduced stroke volume (stroke volume indexed to body surface area ≤ 35ml/m2) despite a normal left ventricular ejection fraction (LVEF > 50%). This entity is termed paradoxical low flow low gradient aortic stenosis (PLFLG AS) and is associated with a worse prognosis. ATTR amyloidosis is a disease of the elderly and might coexist in patients with severe aortic stenosis. Case reports and small observational studies suggest that senile ATTR amyloidosis could be frequent but underdiagnosed in patients with aortic stenosis. There is significant overlap between PLFLG AS and cardiac amyloidosis with regard to symptoms, increasing prevalence with age, concentric hypertrophy, impaired diastolic filling of the left ventricle (LV), as well as longitudinal LV dysfunction despite preserved ejection fraction - all features, which lead to a reduction in stroke volume, the underlying mechanism of the low flow condition as observed in PLFLG AS patients.
Increased circulating b-amyloid and decreased Mitochondrial-derived peptide (MOTS-c), a peptide improving tissue insulin sensitivity, are reported in diabetes. The investigators plan to investigate the association of both biofactors with high on-clopidogrel platelet reactivity and cardiovascular mortality in type 2 diabetic patients with Coronary artery disease
The purpose of this study is to evaluate the efficacy and safety of patisiran in participants with ATTR amyloidosis with cardiomyopathy.
The purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in participants with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran subcutaneous (SC) injection once every 3 months (q3M) or the reference comparator patisiran intravenous (IV) injection once every 3 weeks (q3w) during the 18 month Treatment Period. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints during the 18 Month Treatment Period. Following the 18 Month Treatment Period, all participants will be randomized to receive vutrisiran SC injection once every 6 months (q6M) or q3M in the Randomized Treatment Extension (RTE) Period.
Transthyretin is a protein produced in the liver that transports thyroid hormone and vitamin A. A single substitution of an amino acid in the structure of TTR can result in a relatively unstable protein, the breakdown products of which (predominantly monomers) aggregate abnormally and produce proteinaceous deposits in nerves and the heart. These deposits are known as amyloid and produce progressive nerve and heart damage. Amyloidosis due to a mutant TTR is usually an autosomal dominant and hence is a familial condition. Wild-type TTR is also capable of producing amyloid deposits which predominantly involves the heart (rather than the nervous system) resulting in a progressive decrease in cardiac function with increasing signs of heart failure. This study aims to determine whether subcutaneous injection of an antisense oligonucleotide drug, known as inotersen, that has been specifically designed to reduce production of the protein transthyretin by the liver, can slow or stop the progression of TTR amyloid cardiomyopathy as compared to historical controls, using advanced echocardiography and cardiac MRI. The study also aims to determine the tolerability and safety of this drug when administered over a 24-month period to patients with TTR amyloid cardiomyopathy.
The purpose of this study is to learn if Ixazomib maintenance treatment (chemotherapy) works to control the disease. Through this study, the investigators hope to learn more about ways to prevent or delay relapse of AL Amyloidosis.
