Overview
Brief Summary
The purpose of this study is to evaluate the safety and tolerability of catheter based injections of VM202 into the heart.
Detailed Description
A phase I/II, open label, dose-escalation, multicenter, 12 month study designed to assess the safety and tolerability of catheter based percutaneous myocardial injection of VM202 in patients with chronic refractory myocardial ischemia. The study will consist of three (3) cohorts with a total of 4 subjects enrolled in each cohort. Endocardial injections will be performed with the MyoStar Injection Catheter under guidance of the NOGA XP Cardiac Navigation System.

Eligibility Criteria
Inclusion Criteria
- •Age ≥ 21 years, but less than or equal to 75 years.
- •Stable chronic refractory angina classified as Canadian Cardiovascular Society (CCS) functional class II - IV
- •Left ventricular ejection fraction (LVEF) of ≥30% and ≤ 50%;
- •Clinical signs and symptoms of significant ischemia by treadmill test or Stress imaging (SPECT, Echo or CARDIAC MRI acceptable)
- •Subjects must be able to complete a minimum of 3 minutes, but no more than 10 minutes on a Modified Bruce treadmill protocol.
- •Patients on maximal medical therapy including at least 2 of the following (unless hemodynamic parameters or intolerance contraindicate their use):(a) Long acting nitrate, (b) Beta Blocker or (c) Calcium Channel Blocker (d) Ranolazine. Optimal medical regimen for each subject will be decided by the referring cardiologist or principal investigator. Patients must be on stable medical regimen for 30 days prior to enrollment.
- •Coronary angiogram within 1 year to confirm the presence of coronary disease which is not amenable to standard revascularization procedures.
- •Candidates must not be eligible for any other revascularization procedures. The participant and his/her coronary film must have been discussed with an independent cardiac surgeon and must have been denied for CABG or PTCA. Participants who are marginal or poor candidates for conventional revascularization will be considered eligible if the risks of performing a CABG or PTCA procedure outweigh the potential benefit and/or such a procedure is unlikely to offer a worthwhile clinical benefit. The criteria defining such cases may include, but may not be limited to, the following examples:
- •Diffuse or distal vessel disease
- •Chronic occlusions
Exclusion Criteria
- •Subjects who have undergone a successful revascularization procedure within 6 months of enrollment;
- •MI, unstable angina requiring \> 24 hour hospitalization, or percutaneous coronary intervention, within last 90 days;
- •Stroke or TIA within last 180 days;
- •Predominant CHF symptoms;
- •Hemodynamically significant severe primary valvular heart disease, unless corrected by a properly functional prosthetic valve;
- •Uncontrolled hypertension as defined as systolic BP 170 mmHg or diastolic \> 90 mmHg at baseline/ screening evaluation;
- •Sustained ventricular tachycardia or automatic implantable cardiodefibrillator (AICD) firing within last 180 days;
- •History of ventricular fibrillation;
- •Use of the MyoStar catheter may not be appropriate for patients with prosthetic valves. Patients with a mechanical valve at risk for injury due to the interventional approach should be excluded;
- •Subjects with any comorbidity that may interfere with the ability to perform a maximal treadmill test (e.g. severe arthritis, musculoskeletal disorders, COPD);
