Investigational Trial to Evaluate XC001 Delivered Via an Cardiac Catheter in Subjects With Chronic Angina.

XC001 administered by percutaneous catheter delivery using the Extroducer® Infusion Catheter System.

Subjects randomized to the sham catheterization procedure group will receive the same procedure as the treatment group (with introduction of an iliofemoral or radial sheath, positioning of the pigtail catheter in the left ventricle, generation of ventriculograms, and mimicking of the injection procedure by the interventional team following a Cath Lab script), except they will not have the delivery catheter inserted and will not receive any endocardial injections
