Study information

Scientific title


Northern trial

Study hypothesis

To demonstrate the clinical efficacy and safety of vascular endothelial growth factor (VEGF165) when delivered by direct myocardial injection through the NOGA navigational catheter, to improve myocardial perfusion in patients with severe angina pectoris for whom conventional percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) are either not possible or not ideal. Secondary objective will be to determine the effects of VEGF gene therapy on angina symptoms, patient-perceived quality of life and exercise capacity.

Patient information sheet


Coronary artery disease with severe angina


Randomisation NOGA Catheter Mapping and Administration of Gene Therapy. The NOGA catheter will be passed into the left ventricle across the aortic valve and endocardial mapping carried out. Once the endocardial map is complete, an injection catheter will be introduced into the left ventricle. Patients will be randomly assigned to receive 2 mg of either plasmid DNA encoding the gene for VEGF 165 suspended in phosphate buffered saline or placebo (phosphate buffered saline) in 10 divided injection sites spaced at least 1 cm apart. Injections will be targeted to regions of ischaemia identified by nuclear imaging which correlate with electro-mechanical NOGA map.

Primary outcome measures

Myocardial perfusion - Rest and Stress perfusion Scores (SRS), changes in Summed Stress Scores (SSS) from baseline to 12 weeks follow-up between placebo and VEGF treated groups; this analysis will be repeated at 6 months.

Secondary outcome measures

1. Symptom evaluation (Canadian Cardiovascular Society [CCS] class Seattle Angina Questionnaire)
2. Patient-perceived Quality of Life (36-item Short Form health survey [SF-36] questionnaire)
3. Exercise performance
4. Major Adverse Cardiac Events
