About this trial

The goal of CELL-VAD Pilot trial is to investigate a personalized stem cell therapy approach for patients with advanced non-ischemic chronic heart failure (NICM) who are supported by LVAD. In the clinical trial, the investigators aim to enroll 10 patients with NICM, scheduled for LVAD implantation. After successful LVAD implantation, patients will be enrolled and followed for 2 months to allow for postoperative rehabilitation and heart failure medical therapy and LVAD support optimization. All patients will then undergo autologous CD34+ cell therapy which will be intracoronaryly delivered to the target myocardium using NOGA electromechanical mapping system. All patients will be followed for 6 months after cell therapy. At baseline, and at 1, 3, and 6 months after cell therapy, the investigators will perform comprehensive clinical evaluation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

non-ischemic dilated cardiomyopathy

patient accepted for LVAD support

optimal (or maximal tolerable therapy) heart failure ≥ 2 months

age 18-65 years

Disqualifiers

ischemic cardiomyopathy

Cardiomyopathy with a reversible cause that has not been treated e.g. thyroid disease, alcohol abuse, hypophosphataemia, hypocalcaemia, cocaine abuse, selenium toxicity & chronic uncontrolled tachycardia.

Cardiomyopathy in association with a neuromuscular disorder e.g. Duchenne's progressive muscular dystrophy.

ongoing or recent (less than 1 month) infection

Trial design

Design model

Single group

Treatments tested in this trial

  • CD34+ stem cell therapy

    Biological/Vaccine

    After 5-days GCSF stimulation all patients will undergo apheresis to obtain CD34+ cell which will subsequently be injected in the target coronary artery using microcatheter.
