Inclusion criteria
Inclusion criteria: 1) Meet criteria (1) to (5) below and are confirmed as such by at least 1 specialist qualified by the Japanese Society for Cardiovascular Surgery and at least 1 physician with deep experience Cardiovascular Intervention.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary endpoints: at 6 months after gene transfer - Rate of increase in absolute claudication distance (ACD) - ACD - Peak walking time - Initial claudication distance (ICD) - Claudication onset time | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints: at 6 months after gene transfer - Measurement of oxygen dynamics in the leg muscles by near infrared spectroscopy after a treadmill load test - Proportion of subjects in whom readministration was not required - Evaluation of QOL based on the Walking Impairment Questionnaire (WIQ) - Time-course changes using clinical stage classifications (Fontaine classification, Rutherford classification) - Ankle-brachial pressure index - Toe-brachial pressure index - Time-course changes in pain at rest evaluated by the visual analogue scale - Time-course changes in pain at rest evaluated by the frequency of analgesic use - Incidence of cardiovascular events (to be followed up to 5 years after administration) | — |
