Bone Marrow Derived Adult Stem Cells for Dilated Cardiomyopathy (REGEN-DCM)
Dilated Cardiomyopathy
About this trial
This is an interventional treatment trial for Dilated Cardiomyopathy focused on measuring dilated cardiomyopathy, adult stem cells, bone marrow progenitor cells, bone marrow stem cells, autologous, granulocyte-colony stimulating factor, intracoronary injection, left ventricular function, To determine if patient's own bone marrow derived stem cells can be used to improve cardiac function
Eligibility Criteria
Inclusion Criteria:
- Symptomatic patients with a confirmed diagnosis of dilated cardiomyopathy (NYHA II-III) attending their local 'Heart Failure clinic' who are on optimal heart failure treatment, under supervision from their physician or heart failure nurse specialist, and have no other treatment options
- Patients who are NYHA II that have been hospitalised with a dilated cardiomyopathy related condition
- Coronary angiography will be performed where necessary to confirm the diagnosis and ensure no other conventional treatment options are indicated
- Prior to recruitment to the study patients at risk of ventricular arrhythmia will have undergone electrophysiological assessment and appropriate clinical management (including implantable defibrillator insertion) where indicated (as per NICE guidelines)
Exclusion Criteria:
- NYHA I
- Referral hospitals most recent documented ejection fraction of >45% (any imaging modality)
- The presence of cardiogenic shock
- The presence of acute left and/or right sided pump failure as judged by the presence of pulmonary oedema and/or new peripheral oedema
- Known severe pre-existent left ventricular dysfunction (with a documented ejection fraction of <10% from referral hospital) prior to randomisation
- Congenital cardiac disease
- Cardiomyopathy secondary to 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
- Previous cardiac surgery
- Contra-indication for bone marrow aspiration
- Known active infection
- Known infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), HTLV or syphilis.
- Chronic inflammatory disease requiring ongoing medication
- Serious known concomitant disease with a life expectancy of less than one year
- Follow-up impossible (no fixed abode, etc)
- Patients with an irregular heart rhythm (AF allowed if paced in a regular rhythm)
- Patients with renal impairment (Creatinine >200mmol/L)
- Neoplastic disease without documented remission within the past 5 years
- Weight>140kg
- Subjects of childbearing potential

Experimental
Peripheral
Interventional arm
Half the patients will be randomised to the non-interventional part of the trial. In this subgroup of patients will be randomised 1:1 to 5 day course of subcutaneous placebo injections or a 5 day course of G-CSF(Granocyte™) subcutaneous injections
In the subgroup of the interventional arm patients will be randomised 1:1 to receive a 5 day course of subcutaneous G-CSF (Granocyte™) injections and bone marrow aspiration at day 5, they will then receive either stem cells or placebo via intracoronary injection
