6 Clinical Trials for Various Conditions
The goal of this clinical trial is to learn if sotagliflozin, a dual SGLT1 and SGLT2 inhibitor, works to treat symptomatic, nonobstructive hypertrophic cardiomyopathy (noHCM) in adult patients. It will also learn about the safety of sotagliflozin in this patient population. The main questions it aims to answer are: 1. Will sotagliflozin be well tolerated in patients with nonobstructive HCM? 2. Will sotaglifozin improve exercise capacity, diastolic dysfunction and/or physical functioning in patients with nonobstructive HCM? 3. Will sotagliflozin improve circulating markers of cardiac metabolism in patients with nonobstructive HCM? Researchers will compare sotagliflozin to a placebo (a look-alike substance that contains no drug) to see if sotagliflozin is effective at treating hypertrophic cardiomyopathy (HCM). Participants will: Take sotagliflozin or a placebo every day for 12 weeks. They will then cross-over (or switch) to taking placebo or sotagliflozin (whichever one they did not take initially) for an additional 12 weeks. Visit the clinic once every 4-12 weeks for checkups, surveys, and tests including a stress test and echocardiogram.
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.
This study will test the feasibility of a modified procedure for treating obstructive hypertrophic cardiomyopathy (OHC). Patients with OHC have a thickening of the heart muscle that obstructs blood flow out of the heart, causing breathlessness, chest pain, palpitations, tiredness, lightheadedness, and fainting. The current treatment for OHC is a procedure called alcohol septal ablation (also percutaneous transluminal septal ablation, or PTSA), which involves injecting a small amount of alcohol into a tiny artery that supplies the part of muscle causing blood flow obstruction. The success of PTSA is limited, however, by problems of heart anatomy and the ability to find the appropriate artery to inject. Modifying the procedure by injecting the alcohol through the wall of the lower right chamber of the heart may improve its safety and effectiveness. The new technique requires positioning a catheter (a flexible tube) into the appropriate area of the heart. This study will test the ability to accurately guide the catheter to that area. Patients with OHC 18 years of age and older who are scheduled to have a cardiac catheterization may be eligible for this study. At the end of the catheterization procedure, participants will undergo intra-cardiac echocardiographic imaging. For this test, one of the catheters placed in the femoral artery (at the top of the leg) for cardiac catheterization will be substituted for a larger one. Through this catheter, a special catheter will be introduced and advanced to the heart to provide images. This pilot feasibility study does not involve injection of alcohol.
DDD pacing improves symptoms and relieves LV outflow tract (LVOT) obstruction in most patients with hypertrophic cardiomyopathy (HCM). Notably, when pacing is temporarily discontinued, the beneficial effects of pacing are evident in sinus rhythm. The long term results of this novel therapy are, however, uncertain. We propose (1) to record the hemodynamic changes following \>4 years of pacing; and (2) to determine whether DDD pacing continues to be necessary in patients who have had a substantial relief of their LVOT obstruction. Patients who have had \>50% reduction in LVOT pressure gradients will be randomized to two pacing modalities: DDD at 70 beats per minute and AAI pacing at 70 beats per minute (DDD switched off), and reevaluated after a six-month period.
The purpose of the study is to evaluate the effect between two different single doses of mavamten in healthy participants.
Coronary artery disease (CAD) is caused by a narrowing of the blood vessels that supply blood and oxygen to the heart. Balloon angioplasty and stent placement are two treatment options for people with reduced heart function caused by CAD. This study will use magnetic resonance imaging (MRI) procedures to evaluate heart function over time in people with CAD who have undergone a balloon angioplasty or stent placement procedure.
