Active clinical trials for "Cardiomyopathies"

The purpose of this phase 2 open-label pilot study is to evaluate the efficacy, pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of MYK-461 in subjects with symptomatic HCM and LVOT obstruction aged 18-70 years.

The goal of this observational study is to demonstrate the ability of using non-invasive Phosphorus (31P) Magnetic Resonance Spectroscopy (MRS) to monitor changes of in-vivo markers of mitochondrial function in skeletal and cardiac muscles in muscles in large B- or T-cell lymphoma patients during treatment with (R-)CHOP. The main question it aims to answer is: • Can 31P-MRS be used to monitor changes of in vivo markers of mitochondrial function in skeletal and cardiac muscles in large B- or T-cell lymphoma patients during treatment with (R-)CHOP? To be able to answer this main question, participants will undergo 31P-MRS imaging of the calf muscles and of the heart 3 times during the study period.

The goal of this observational study is to test the accuracy of computer (machine learning-based) algorithms to diagnosis heart diseases and predict if and when heart complications will occur. The AID-MRI research team has developed algorithms aimed at modelling 3D heart structure and movement (deformation), showing these may be of value to achieve these tasks. The International AID-MRI study aims to test the performance of these algorithms across 11 international sites, using data obtained from a broad variety of patients using different MRI scanners. In addition to an established cohort of 10,000 patients, AID-MRI will recruit an additional 1100 patients from its international sites, these serving as an external validation cohort.

Male subjects with cardiomyopathy secondary to Duchenne muscular dystrophy (DMD) meeting all inclusion and no exclusion criteria will be randomized. All subjects will be at least 12 years of age. They will be randomized in a 1:1 manner to either intracoronary infusion of CAP-1002 in three coronary arteries supplying the three major cardiac territories of the left ventricle of the heart (anterior, lateral, inferior/posterior) or usual care. In the active treatment arm, all three major cardiac territories will be treated (infused) during a single procedure in an open-label fashion.

The purpose of this study is to investigate the effect of COR-1 in combination with standard therapy in patients with heart failure. The safety and tolerability of COR-1 will also be assessed.

This is a pilot study to evaluate the safety and efficacy of the Algisyl-LVR™ device. The purpose of this study is to investigate Algisyl-LVR™ employed as a method of left ventricular augmentation and restoration in patients with dilated cardiomyopathy. Algisyl-LVR™ will be injected into the myocardium under direct visualization during the surgical procedure. This study will evaluate the concept that direct mid left ventricular (LV) intramyocardial injections of Alginate hydrogel implants into the free wall of the failing LV will reduce LV size, restore LV shape, lower LV wall stress and improve global LV function. The Primary Efficacy Endpoint of the study is the change in Peak VO2 (maximum oxygen uptake) from baseline to 6 months of follow-up. The Primary Safety Endpoint of the study is to estimate the 30 day mortality associated with the implantation of the Algisyl-LVR device The hypothesis of the study is that there is a statistically significant difference in change in Peak VO2 from baseline to 6 month follow-up when the medically managed arm is compared to the Algisyl-LVR arm, i.e. the Algisyl LVR arm is superior to medical management.

BACKGROUND. In patients with non-ischemic dilated cardiomyopathy, intracoronary stem cell transplantation has been shown to improve exercise capacity, reduce ventricular remodelling and improve 1-year survival. Pre-clinical data demonstrate that stem cell effects on the diseased heart can be further enhanced by direct intramyocardial delivery route. AIMS. To evaluate safety and efficacy of intramyocardial stem cell therapy in patients with non-ischemic dilated cardiomyopathy. To directly compare clinical effects of intracoronary and intramyocardial stem cell delivery. METHODS. Of 60 patients with dilated cardiomyopathy, 30 will be randomized to intramyocardial transplantation of CD34+ cells (Study Group), and 30 will receive intracoronary stem cell therapy (Control Group). In both groups peripheral blood stem cells will be mobilised by daily subcutaneous injections of filgrastim; CD34+ cells will be collected via apheresis and labelled with technetium. In the Study Group electromechanical mapping will be used to identify viable myocardium and intramyocardial injections in the target areas will be performed with NOGA catheter. In the Control group patients will undergo myocardial perfusion scintigraphy and CD34+ cells will be injected intracoronary in the artery supplying segments of reduced viability. Patients will be followed for 1 year. Primary endpoints will include changes in left ventricular ejection fraction and left ventricular dimensions (measured by echocardiography). Secondary endpoints will include changes in exercise capacity and changes in NT-proBNP values. HYPOTHESES. At 1 year, intramyocardial stem cell therapy will be associated with improved left ventricular ejection fraction, reduced left ventricular dimensions, improved exercise capacity and reduced levels of NT-proBNP. Beneficial effects of intramyocardial stem cell therapy will be superior to those observed with intracoronary stem cell delivery.

This Phase 3 study will investigate the efficacy, safety and tolerability of an oral daily dose of 20 mg or 80 mg tafamidis meglumine capsules compared to placebo in subjects with either transthyretin genetic variants or wild-type transthyretin resulting in amyloid cardiomyopathy.

This is a Phase 2 pilot study, involving a 48-week treatment period, designed to test the effectiveness of investigational study drug ARRY-371797 in treating patients with symptomatic genetic dilated cardiomyopathy due to a lamin A/C gene mutation, and to further evaluate the drug's safety. Approximately 12 patients from the US will be enrolled in this study.

The purpose of this study was to evaluate the safety and efficacy of revusiran (ALN-TTRSC) in patients with transthyretin (TTR) mediated Familial Amyloidotic Cardiomyopathy. Dosing has been discontinued; patients are being followed-up for safety.
