Study information
Study design | Randomised, double blind, interventional study |
---|---|
Primary study design | Interventional |
Secondary study design | Randomised controlled trial |
Study setting(s) | Hospital |
Study type | Treatment |
Scientific title | |
Study acronym | The PRIMATIVE Study |
Study objectives | Autologous bone-marrow derived stem cells delivered percutaneously to the damaged myocardium via the heart attack related artery can significantly improve left sided heart function after a heart attack without significant adverse effects. This impact is evident even if the bone marrow cells are delivered late after the index event. |
Ethics approval(s) | Ethics approval received from the Leicestershire, Northamptonshire and Rutland Committee 1 on the 12th December 2006 (ref: 06/Q2502/58). EudraCT number: 2006-003319-39. |
Health condition(s) or problem(s) studied | Coronary Heart Disease |
Intervention | Status of trial amended to 'stopped' as of 05/04/2013 due to notification that it was not started. The control group will receive a placebo stem cell transfusion made up of autologous heparinised plasma and the study group will receive autologous Stem Cell Therapy (SCT). The following measurements will be made: 1. Coronary Angiogram 2. Four Magnetic Resonance Imaging (MRI) scans 3. Bone marrow cell aspiration 4. Stem cell transfusion 5. Holter monitoring 6. Atrial Natriuretic Peptide (ANP)/Brain Natriuretic Peptide (BNP) blood samples 7. Cardiac markers samples |
Intervention type | Other |
Primary outcome measure | Improvement in left ventricular function is determined by the comparison of the mean left ventricular EF in the stem cell treated and control groups, measured on initial MRI and that at four months in the early stem cell group and comparison of mean left ventricular EF measured at four months and one year in stem cell treated and control in the late treatment group. Maintenance of benefit will be assessed by comparison of EF at 12 months in subjects randomised to SCT in the early treatment group. |
Secondary outcome measures | 1. All cause and cardiac mortality at 12 months 2. Troponin and CK enzyme rise at 12 months post all interventional procedures 3. Hospitalisation for heart failure (symptoms of dyspnoea at minimal effort or at rest despite conventional treatment) at twelve months 4. Recurrent MI within 12 months 5. Need for revascularisation (exercise tolerance test positive)(PCI/CABG) to Target Lesion Revascularisation (TLR) and non-TLR at four and 12 months 6. Hospitalisation for arrythmias 7. Presence of malignant arrythmias (ventricular fibrillation, ventricular tachycardia, frequent ventricular ectopics) on 24 hour Electro cardiogram (ECG) monitoring at one, six and 12 months 8. ANP/BNP measured at baseline, four and 12 months 9. Inflammatory status (full blood leucocytes count and C-Reactive Protein performed pre- and post- SCT) 10. Scar size assessed by Gadolinum enhanced MRI scans in 50% each group |
