Brief summary

The utility of GP1101 will be evaluated relative to that of surgical bypass in the treatment of Femoral/Popliteal Arterial Symptomatic Peripheral Arterial Disease. Efficacy will be measured by comparison to a Surgical Bypass Efficacy Goal, and Invasiveness will be measured by comparison to Surgical Bypass data derived from a retrospective study.

Retrospective Surgical Bypass Outcomes
Retrospective data collection (Apr 2012 - Apr 2014) of 68 surgical procedures (performed after Jan 2002) at six Japanese centers used to treat femoral-popliteal artery symptomatic PAD for purposes of establishing the invasiveness control data for hospital stay duration, avoidance of general anesthesia and avoidance of intra-operative transfusion. Eligibility criteria for inclusion were established to be consistent with the experimental arm.
