Safety Study of Gene Therapy in Treating Critical Leg Ischemia

The study will consist of four (4) cohorts with a total of 3 subjects enrolled in each cohort to VM202.For each dose cohort, VM202 will be administered as a local intramuscular injection in 2 divided doses with a 2-week interval between the injections. Preliminary efficacy (hemodynamic assessments), safety and tolerability will be evaluated at Baseline (screening) and at designated time points throughout the study. After the first subject in each cohort completed Day 30 (±2 days), and before the Day 15 dosing of the other 2 subjects in the same cohort, an interim safety evaluation was performed with the submission of safety data to the Data Safety Monitoring Committee. All four dose cohorts will be followed for up to 5 years from the time of the first dose of study drug administration.
