Overview
Brief Summary
A study to assess the safety and preliminary efficacy of serial intravenous dose of Allogeneic Mesenchymal Bone Marrow Cells in subjects with heart failure and implanted left ventricular assist devices.

Eligibility Criteria
Inclusion Criteria
- •Age ≥18 years.
- •Advanced Heart Failure
- •Advanced HF defined as HF requiring LVAD implantation and deemed stable on his/her LVAD.
- •On stable medical therapy (per the discretion of the treating physician) including beta-blockers, ACE-inhibitors, angiotensin receptors blockers, angiotensin receptor neprilysin inhibitor, mineralocorticoid receptor antagonists, isosorbide, hydralazine, and mineralocorticoid receptor antagonists) and optimized pump speed for at least a month prior to randomization.
- •HS-CRP level≥2 mg/l.
