TXA127 in Non-Ambulant Patients With DMD Cardiomyopathy
DMD-Associated Dilated CardiomyopathyThis open-label, single-arm multi-center study studying the safety and efficacy of TXA127 on non-ambulant patients with DMD Cardiomyopathy will comprise of two phases: 6-month open-label treatment phase: Male DMD patients with documented cardiomyopathy, will receive a daily subcutaneous injection of TXA127 0.5 mg/kg. Treatment will be provided for 6 months. Treatment safety will be assessed by collection and review of AEs, vital signs, ECGs, physical examinations, PFTs, and laboratory parameters on Day 1, Month 1, and Month 6. Ejection Fraction, upper extremity strength and biomarker levels will be assessed at these study visits as well. In addition, an abbreviated safety visit will be conducted at Month 3. 12-month optional extension phase: Patients will continue the same study drug regime for an additional 12 months. The primary objective of this phase is to obtain long-term safety data. Efficacy data will also be collected. Safety, efficacy, and exploratory biomarkers will be assessed at Month 12 and Month 18, using the same methods as in the treatment phase. In addition, abbreviated safety visits will be conducted at Month 9 and Month 15.

Treating Congestive HF With hiPSC-CMs Through Endocardial Injection
Cardiovascular DiseasesCongestive Heart Failure1 moreHeart failure is the primary cause of morbidity and mortality worldwide. Currently drug treatments for heart failure manage the symptoms, but not restore the loss cardiomyocytes due to the very limited regenerative capability in the adult heart. Novel reparative therapies that replace the cardiomyocytes loss are highly demanded to restore the cardiac function. The main purposes of this explanatory study is to investigate the safety and efficacy of the catheter-based endocardial delivery of human iPSC-derived cardiomyocytes in patients with congestive heart failure.
Examining the Effects of Mitochondrial Oxidative Stress in DCM
Dilated CardiomyopathyDouble blind, randomised, placebo-controlled trial of MitoQ (mitoquinol mesylate) in 106 patients with dilated cardiomyopathy, examining the effect of reducing mitochondrial oxidative stress on myocardial energetics and myocardial function using 31-phosphorus magnetic resonance spectroscopy and cardiovascular magnetic resonance.
Conduction System Pacing Versus Biventricular Pacing for Cardiac resYNChronization
Dilated Cardiomyopathy With Conduction DefectLeft Bundle-Branch Block4 moreCardiac resynchronization therapy (CRT) with biventricular pacing (BiV) is the cornerstone treatment for heart failure patients with ventricular dyssynchrony. Recently, a new concept, conduction system pacing (CSP) with permanent pacing, including His bundle pacing and left bundle branch pacing, has been proposed as a potential alternative to conventional BiV-CRT. The prospective, randomized trial will compare echocardiographic, electrocardiographic, and clinical effects of CSP versus conventional BiV pacing in heart failure patients with reduced ejection fraction (LVEF ≤ 35%), sinus rhythm, and left bundle branch block. Patients will be randomized to either CSP or biventricular pacing study group and followed up for at least 6 months. The study will explore whether CSP is non-inferior to BiV pacing in echocardiographic, electrocardiographic, and clinical outcomes.

Arrhythmic Risk Stratification in Nonischemic Dilated Cardiomyopathy
Sudden Cardiac Death Due to Cardiac ArrhythmiaDilated CardiomyopathyNonischemic dilated cardiomyopathy is a heterogeneous disease often associated with increased rates of sudden cardiac death. Although many algorithms have been proposed, risk stratification remains suboptimal, and implantable cardioverter-defibrillators are currently recommended only in patients with poor left ventricular function. However, most cases of sudden cardiac death occur at earlier stages, in patients with relatively preserved left ventricular function and exercise capacity, for which device-therapy is currently not indicated. Several noninvasive risk factors have been associated with increased arrhythmic risk, including clinical history (syncope), imaging (fibrosis on cardiac magnetic resonance imaging and left ventricular dimensions in echocardiography) and electrocardiographic parameters (ventricular arrhythmic burden, late potentials, heart rate variability and repolarization abnormalities). The investigators hypothesized that the encouraging findings of studies assessing more sophisticated stratification-algorithms in patients with ischemic heart disease could be extrapolated in patients with nonischemic dilated cardiomyopathy. Thus, combining noninvasive risk factors with programmed ventricular stimulation may risk-stratify such patients more accurately. In this regard, the prospective observational multicenter ReCONSIDER study aims to integrate several approaches to arrhythmic risk stratification in nonischemic dilated cardiomyopathy in a tiered, multifactorial, approach, in which noninvasive risk factors are combined with electrophysiologic studies. This approach may pave the way for a more comprehensive risk stratification algorithm in patients with nonischemic dilated cardiomyopathy, leading to more rational device-therapy, and, ultimately to lower mortality.
Absolute Coronary Flow in Patients With Heart Failure With Reduced Ejection Fraction and Left Bundle...
Left Bundle-Branch BlockHeart Failure2 moreCardiac resynchronization therapy (CRT) is an effective therapeutic strategy in patients with symptomatic heart failure (HF) patients with LVEF of ≤35% and left bundle branch block (LBBB). However, approximately one-third of CRT-recipients do not improve after therapy (non-responders), despite meeting the required criteria. Previous studies have documented that the positive respons to CRT is related to the delayed electrical activation of the left ventricle in patients with LBBB. It has also been illustrated that non-ischemic CRT-candidates with LBBB demonstrate lower regional myocardial blood flow and metabolism in the septum. Additionally, it has been suggested that LBBB can lead to impaired coronary blood flow in the left anterior descending artery (LAD). This observation is based on an echocardiography-based study, that showed that the percentage of diastolic flow duration (%DD) in LAD was shorter in patients with LBBB compared to the control-group and patients with right-ventricular pacing. It has been demonstrated that CRT has positive effects on septal myocardial perfusion in patients with HF and LBBB. The dominant hypothesis explaining this phenomenon is built on improved septal myocardial work after CRT-implantation, which leads to increased myocardial energy and therefore increased myocardial perfusion. In contrast, it has been suggested that due to re-established synchronous left ventricular electrical activation, CRT reduces the septal intramyocardial pressure in early diastole, leading to a relatively longer antegrade flow duration in LAD. Therefore, the aim of the study is to evaluate the effect of CRT on coronary blood flow in LAD in patients with non-ischemic HF and LBBB. The investigators hypothesize that increased LV-function after CRT not only is due to resynchronized LV ejection and filling, but also improved coronary flow. The study aims to enroll 60 patients with heart failure due to non-ischemic dilated cardiomyopathy, LBBB, with or without CRT. All patients meeting the criteria will be recruited from the outpatient clinic at the Department of Cardiology, Aalborg University Hospital. Invasive flow measurements in the LAD, including fractional flow reserve (FFR), absolute coronary flow and -reserve will be conducted with the CRT on and off, respectively.
