The purpose of this study is to evaluate the safety of two doses of PVS-10200, an allogeneic cellular therapy, delivered as a single injection following percutaneous transluminal ("balloon") angioplasty and stent placement for the treatment of peripheral artery disease (PAD).
This is an open-label dose escalation safety study of PVS-10200 in 30 subjects with peripheral artery disease (PAD) requiring balloon angioplasty and stent placement in the superficial femoral artery (SFA). The study will be completed sequentially in two dose cohorts of 10 subjects (low dose group, Cohort A) and 20 subjects (high dose group, Cohort B). A Data Safety Monitoring Board (DSMB) will conduct regular safety reviews. Each subject will receive one treatment of PVS-10200 delivered by ultrasound guided injection to the perivascular region (external to the vessel) of the stented target lesion. The treatment will be administered within 24 hours after balloon angioplasty/stent placement.

Maintenance of Primary Patency of Superficial Femoral Artery (SFA)
Primary patency was defined as duplex ultrasound peak systolic velocity \[PSV\] ratio ≤2.4.Ultrasound data was obtained for each patient at each time point and had to be considered diagnostic and evaluable by the core lab; if it was not, then this analysis could not be done for that particular subject.

Rate of Binary In-stent Restenosis
Binary restenosis relied on duplex ultrasound data with a Yes/No assessment with 0-49% being No (peak systolic velocity \[PSV\] ratio ≤2.4) and Yes being 50-99% (PSV ratio \>2.4), with the PSV ratio calculated as PSV from stenosis divided by the PSV from a normal segment of artery proximal to the stenosis. Ultrasound data was obtained for each patient at each time point and had to be considered diagnostic and evaluable by the core lab; if it was not, then this analysis could not be done for that particular subject.

Resting Ankle-brachial Index
ABI was calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressures in the arm. This test is used to predict the severity of PAD.
Time frame: within 4, 24 and 48 weeks from study procedure
Changes in Physical Exam
Changes in physical examination were compared to baseline: numbers of subjects presenting any new finding or worsening of abnormal findings compared to the screening examination are reported
Time frame: within 4, 24 and 48 weeks from baseline
