NCT ID: NCT06240403 Not yet recruiting - Clinical trials for Diabetes Mellitus, Type 2

Digoxin and Senolysis in Heart Failure and Diabetes Mellitus

Start date: September 1, 2024
Phase: Phase 2
Study type: Interventional

In pilot studies the investigators have shown that subcutaneous adipose tissue (SAT) from patients with reduced ejection fraction heart failure (HFrEF) and type 2 diabetes mellitus (T2DM) is dysfunctional. Endothelial cells from the adipose tissue from these patients are senescent and have deleterious effects on healthy human subcutaneous adipocytes, including increasing expression of IL-6 (gene and protein) and reducing glucose uptake. Digoxin, a well-established treatment for HFrEF, selectively clears these senescent endothelial cells and prevents adipocyte dysfunction. This study will examine the effect of digoxin on adipose tissue on the burden of senescent cells.

Physiological Effects of Lactate in Individuals With Chronic Heart Failure

Start date: November 22, 2023
Phase: N/A
Study type: Interventional

Background: Lactate is continuously produced in the human body through two primary processes: glycolysis and microbial fermentation in the gastrointestinal tract. At rest, its concentration in the bloodstream typically ranges from 1 to 2 mmol/L. However, during periods of physical exertion or insufficient oxygen supply, such as during intense exercise, lactate levels significantly increase. Traditionally, lactate was perceived as a byproduct of anaerobic metabolism. Nevertheless, emerging research has illuminated its vital role as both a signaling molecule and a crucial energy source for vital organs like skeletal muscle, brain, and the heart. Objectives: The primary aim of this study is to investigate the impact of physiological levels of circulating lactate on the hemodynamics of individuals with chronic heart failure. This research seeks to understand how lactate affects the cardiovascular response in this specific patient population. Design and Endpoints: The study design employs a double-blind, randomized crossover approach involving 12 heart failure patients. Each participant will undergo two separate visits. Visit 1: Participants will receive a three-hour intravenous infusion of either a racemic (D/L) mixture of sodium lactate or an intravenous isotonic sodium chloride placebo, with a subsequent crossover to the opposite infusion on the same day. Visit 2: Similar to the first visit, participants will receive either an orally administered racemic (D/L) mixture of sodium lactate or an isocaloric, isovolumic oral placebo (maltodextrin), with a crossover to the opposite administration after three hours. The study's endpoints include cardiac output (primary), mixed venous saturation (SVO2), pulmonary wedge pressure, resting echocardiography (left ventricular ejection fraction and myocardial work efficiency), and measurements of vasoactive substances in blood samples. Methods: The study employs invasive Swan-Ganz monitoring to measure cardiac output, echocardiography, and frequent venous blood sample collections. These measurements and samples will be taken at specific intervals during the study visits. Intervention: To investigate the isolated hemodynamic and physiological effects of lactate, the study utilizes lactate infusion and ingestion to induce a state of hyperlactatemia within the physiological range. The intended dosages aim to stay within the physiological range, with no values expected to exceed 3-4 mmol/L.

Beneficial Effects of Vitamin D Combined With Oral Iron Supplementation in Patients With Chronic Heart Failure and Iron Deficiency

VICTORID-HF
Start date: January 15, 2024
Phase: Phase 4
Study type: Interventional

The goal of this randomized, controlled, open-label, interventional study is to evaluate whether, in patients with heart failure (HF) and iron deficiency (ID), the administration of vitamin D in combination with sucrosomial iron is as effective as intravenous ferric carboxymaltose in improving symptoms of HF. The main hypothesis which the study aims to test is the non-inferiority of sucrosomial iron (± vitamin D) compared with FCM treatment, after 24 weeks. Primary endpoint: the performance of the Six-Minute Walking Test, comparing the mean difference from baseline of the distance walked by patients in meters. Participants will be evaluated in outpatient scheduled visits at 6, 12 and 24 weeks, performing blood tests, clinical evaluation, instrumental investigations and recording any adverse events, cardiovascular events, re-hospitalizations and fractures. The study will involve randomization into 3 groups with a 1:1:1 ratio: 1. Control group [standard of care]: administration of FCM (Ferinject®) with a dose between 500 and 2000 mg (depending on body weight and hemoglobin values), to be administered in 1 or 2 doses (time 0 ± 6 weeks) with possible additional administration of 500 mg at week 12 in case of persistent ID. 2. Sucrosomial iron group: administration of sucrosomial iron (SiderAl Forte®) at a dose of 60 mg (2 tablets) once a day for 24 weeks. 3. Sucrosomial iron and vitamin D group: administration of sucrosomial iron (SiderAl Forte®) at a dose of 60 mg (2 tablets) once daily + vitamin D3 (100,000 IU load at time 0, then 2,000 IU daily) for 24 weeks

NCT ID: NCT05632432 Not yet recruiting - Clinical trials for Coronary Artery Disease

Atrial Appendage Micrograft Transplants to Assist Heart Repair After Cardiac Surgery

AAMS2
Start date: December 1, 2022
Phase: N/A
Study type: Interventional

Ischemic heart disease (IHD) leads the global mortality statistics. Atherosclerotic plaques in coronary arteries hallmark IHD, drive hypoxia, and may rupture to result in myocardial infarction (MI) and death of contractile cardiac muscle, which is eventually replaced by a scar. Depending on the extent of the damage, dysbalanced cardiac workload often leads to emergence of heart failure (HF). The atrial appendages, enriched with active endocrine and paracrine cardiac cells, has been characterized to contain cells promising in stimulating cardiac regenerative healing. In this AAMS2 randomized controlled and double-blinded trial, we use the patient's own tissue from the right atrial appendage (RAA) for therapy. A piece from the RAA can be safely harvested upon the set-up of the heart and lung machine at the beginning of coronary artery bypass (CABG) surgery. In the AAMS2 trial, a piece of the RAA tissue is processed and utilized as epicardially transplanted atrial appendage micrografts (AAMs) for CABG-support therapy. In our preclinical evaluation, epicardial AAMs transplantation after MI attenuated scarring and improved cardiac function. Proteomics suggested an AAMs-induced glycolytic metabolism, a process associated with an increased regenerative capacity of myocardium. In an open-label clinical trial, we have demonstrated the safety and feasibility of AAMs therapy. Moreover, as this study suggested increased thickness of the viable myocardium in the scarred area, it also provided the first indication of therapeutic benefit. Based on randomization with estimated enrolment of a total of 50 patients with 1:1 group allocation ratio, the piece of RAA tissue is either perioperatively processed to AAMs or cryostored. The AAMs, embedded in a fibrin matrix gel, are placed on an extracellular matrix sheet (ECM), which is then epicardially sutured in place. The location is determined by preoperative late gadolinium enhancement cardiac magnetic resonance imaging (LGE-CMRI) to pinpoint the ischemic scar. Study blood samples, transthoracic echocardiography (TTE), and LGE-CMRI are performed before and at 6-month follow-up after the surgery. The trial's primary endpoints focus on changes in cardiac fibrosis as evaluated by LGE-CMRI and circulating levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP). Secondary endpoints center on other efficacy parameters, as well as both safety and feasibility of the therapy.

Ferric Carboximaltose on Intra-myocardial Iron Load in Patients With Heart Failure

IronHeart
Start date: August 30, 2019
Phase: Phase 4
Study type: Interventional

In general, anemia is associated with a greater presence of HF symptoms, worsening NYHA functional class, higher rate of hospitalization for heart failure, and reduced survival. However, it is unclear whether anemia is the cause of decreased survival or a marker for more advanced disease. Correction of iron deficiency in patients with New York Heart Association (NYHA) class II or III HF using intravenous iron (Ferinject®) improved "overall patient self-assessment" and NYHA functional class of 6-minute walk and health-related quality of life) in the FAIR-HF trial. It is unknown if iron deficiency is correlated with intra-myocardial iron load as assessed by cardiac magnetic resonance (CMR) and if the treatment with intravenous iron has any impact on intra-myocardial iron load and left ventricular function. The aim of the present study is to evaluate the effect of intravenous iron replacement on intra-myocardial iron deposits and the effect on left ventricular function. Because it is a pilot study with few data in the literature, it is planned to use an initial sample of 20 patients. We aim to evaluate the global ventricular function, the iron load by the T2 * method, the cardiac strain, the "Fiddle" and the "Fat water" of each patient by CMR. After this examination, patients will undergo intravenous infusion of 1g of Ferric Carboxymaltose (Ferinject®). A comparative analysis of the ejection fraction values at the beginning and at the end of the study by CMR will be performed, in addition to a clinical reassessment. The inclusion criteria will be: Patients older than 18 years, with iron deficiency and reduced ejection fraction defined as: serum ferritin <100 μg / L or with ferritin 100-299 μg / L with transferrin saturation <20 %; Hemoglobin <12g / dL in women and <13g / dL in men; Clinical stability in the last 3 months; Left ventricular ejection fraction (LVEF) <40% assessed by transthoracic echocardiography or CMR in the last 3 months. The exclusion criteria will be: patients with preserved ejection fraction (> 50%), pregnant women, refusal to participate in the present study, implantable pacemaker or implantable defibrillator incompatible with MRI, cerebral cerebral aneurysm clip and/or intracerebral or intraocular metal fragments, electronic cochlear implants, patients with claustrophobia, patients with clinical or hemodynamic instability and patients with indication for blood transfusion (Hb ≤ 7g / dL).

NCT ID: NCT03392740 Not yet recruiting - Clinical trials for Heart Failure, Systolic

Prophylactic Lisinopril to Prevent Anthracycline Cardiomyopathy.

Start date: March 15, 2018
Phase: Phase 4
Study type: Interventional

The intent of the study is to show the potential benefits of angiotensin converting enzyme inhibitors in preventing anthracycline induced cardiotoxicity. This is a prospective, randomized, blinded and placebo-controlled clinical trial that will enroll patients who are to be treated with anthracycline chemotherapy (doxorubicin, epirubicin, idrarubicin, or mitoxantone) to either lisinopril or placebo group. The study will be performed at the Genesys Hurley Cancer Institute. The treating oncologist who intends to start the patient on anthracycline chemotherapeutic agent will provide the patient with a recruitment flyer and informed consent form and then referred to the research nurse. Subjects interested in participation, that do not meet any of the exclusion criteria, will be consented and enrolled by the research nurse prior to their first treatment with chemotherapy. Over a period of 1 to 3 weeks the study medication will be titrated in a stepwise fashion to a target of 20 mg daily, maintaining a systolic blood pressure greater than 90 mmHg. A baseline echocardiogram with strain and strain rate imaging will be obtained prior to initiation of anthracycline chemotherapy. Subsequent echocardiograms with strain and strain rate imaging will be performed every 3 months for a total of 12 months. Patients will be followed for a total of 12 months, starting on the day of enrollment. We intend to recruit a total of 200 patients. The primary endpoint of this study is a change in change in strain and strain rate parameters prior to, during, and after anthracycline chemotherapy compared to placebo. Study data will be collected and managed using the Ascension installation of REDCap (Research Electronic Data Capture). REDCap is a secure, web application designed to support data capture for research studies, providing user-friendly web-based case report forms, real-time data entry validation (e.g. for data types and range checks), audit trails and a de-identified data export mechanism to common statistical packages. Echocardiographic data will be stored in cine-loop format on a private, password protected echocardiogram viewing software and analyzed by a separate blinded cardiologist. Patients will be evaluated according to the standard oncologic evaluation. The treating oncologist will make decisions on their treatment based on their personal standards and clinical judgement.
