Harefield Recovery Protocol Study for Patients With Refractory Chronic Heart Failure
Stopped early · Phase 1
Conditions studied: Heart Failure, Dilated Cardiomyopathy
In brief
The purpose of this study is to evaluate whether patients with chronic heart failure not due to coronary artery disease who require use of a left ventricular assist device (LVAD) for refractory heart failure can recover sufficient heart function to allow the pump to be explanted. The study aims to avoid the need for transplantation in these patients by using standard heart failure medications to reduce the size of the left ventricle and then using the investigational drug, clenbuterol, to further improve left ventricular function.

You may qualify if…
- Patients with refractory symptomatic heart failure (NYHA Class IV, or Stage D) due to dilated, non-ischemic cardiomyopathy who meet the following criteria:
- Severe clinical heart failure with associated haemodynamic compromise resistant to intensive medical therapy and requiring LVAD implantation
- Duration of heart failure symptoms to be ≥ 12 months prior to LVAD implant
- Documentation of LVEF ≤ 40% at least 1 year prior to LVAD implantation
- LVEF ≤ 30% and cardiomegaly at the time of LVAD implantation as documented by radionuclide or contrast ventriculography or by echocardiography
- Nonischemic etiology confirmed by coronary angiography within two years of enrollment
- Listed for heart transplantation or plan to list for heart transplantation pending successful LVAD implantation in one of the participating centers, as per usual transplant listing policy at each participating center
- >= 18 years of age
- Body surface area >= 1.5 m2
- Have an implantable defibrillator in place or a commitment to implant an ICD prior to hospital discharge
