Brief Summary:
The primary purpose of this trial is to determine the safety of XC001 (AdVEGFXC1) in patients who suffer from angina caused by coronary artery disease and have no other treatment options. Subjects in this study will receive one of four intramyocardial doses of XC001 that expresses human vascular endothelial growth factor (VEGF) which induces therapeutic angiogenesis (revascularization).

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Ischemia Angina Refractory Cardiovascular Diseases Heart Diseases Biological: AdVEGFXC1 Phase 1 Phase 2

Detailed Description:
This is a Phase 1/2, first-in-human, multicenter, open-label, single arm dose escalation trial of XC001. Approximately 12 subjects (N=3 per cohort) who have refractory angina will be enrolled into 4 ascending dose groups, followed by an expansion of the highest tolerated dose with 32 additional subjects. XC001 will be administered by a transthoracic epicardial procedure. Safety will be the focus for the initial 6 months after XC001 administration followed by one safety focused telephone evaluation at Month 12.
