Study Description
Brief Summary:
A randomised, double-blind, placebo-controlled trial to evaluate the role of intracoronary injection of progenitor cells compared to placebo injection in patients with Dilated Cardiomyopathy who have been pre-treated with G-CSF (Granocyte™) injections for 5 days, and patients treated with a 5 day course of G-CSF (Granocyte™) injection only compared to placebo injection

Condition or disease Intervention/treatment Phase
Dilated Cardiomyopathy Drug: granulocyte colony stimulating factor (GCSF) Procedure: bone marrow mononuclear cells Phase 2

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomised Controlled Trial to Compare the Effects of G-CSF (Granocyte™) and Autologous Bone Marrow Progenitor Cells on Quality of Life and Left Ventricular Function in Patients With Idiopathic Dilated Cardiomyopathy
Study Start Date : August 2010
Primary Completion Date : December 2012
Study Completion Date : July 2013

Arms and Interventions

Arm Intervention/treatment
Experimental: Peripheral
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
Drug: granulocyte colony stimulating factor (GCSF)
10mcg/kg per day 5 days
Other Name: Lenograstim, Granocyte™, Chugai Pharma UK, Limited
Experimental: Interventional arm
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
Procedure: bone marrow mononuclear cells
intra coronary injection of stem cells or placebo

Outcome Measures

Primary Outcome Measures :
  1. Change in left ventricular ejection fraction as measured by cardiac magnetic resonance imaging or computerised tomography [ Time Frame: 3 months ]

Secondary Outcome Measures :
  1. Change in: Concentrations of N-terminal prohormone of brain natriuretic peptide (cardiac enzyme) [ Time Frame: 3 months and 12 months ]
  2. Changes in V02 max (exercise capacity) [ Time Frame: 3 months and 12 months ]
  3. Changes in left ventricular ejection fraction, ventricular dimensions as measured by cardiac magnetic resonance imaging or computerised tomography [ Time Frame: 3 months and 12 months ]
  4. Functional class changes according to NYHA and quality of life (QoL - EQ-5D & Kansas City) questionnaires [ Time Frame: 3 months and 12 months ]
  5. Occurrence of a Major Adverse Cardiac Event (MACE) defined as cardiac death, myocardial infarction (CK / CK-MB over 2 times the upper limit of normal) [ Time Frame: 3 months and 12 months ]
  6. Hospitalization for Heart failure & the occurrence of major arrhythmias defined as symptomatic ventricular tachycardia or survived sudden death [ Time Frame: 3 months and 12 months ]
  7. The occurrence of major arrhythmias defined by symptomatic ventricular tachycardia or survived sudden death [ Time Frame: 3 months and 12 months ]

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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

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
