Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Major Adverse Event (MAE) | 30 days | Primary safety endpoint is freedom from MAE which is defined as a composite of: * Death due to all causes * Index limb major amputation (at or above the ankle) * Clinically-driven target lesion revascularization (TLR) |
| Freedom From Vessel Patency | 0 to 365 days | This is the primary effectiveness endpoint which is defined as the absence of in-stent restenosis (≥ 50%) as determined by duplex ultrasonography or arteriography and without clinically driven TLR. The vessel patency rate was estimated by the Kaplan-Meier method with the standard error estimated using the Greenwood formula. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acute Success : Technical Success | With in 2 days of index post procedure | Technical success: Device success plus attainment of final residual stenosis of \< 30% |
| Freedom From Vessel Patency | 0 to 30 days | This is the primary effectiveness endpoint which is defined as the absence of in-stent restenosis (≥ 50%) as determined by duplex ultrasonography or arteriography and without clinically driven TLR. The vessel patency rate was estimated by the Kaplan-Meier method with the standard error estimated using the Greenwood formula. |
| Ankle Brachial Index (ABI) for the Treated Limb | Pre-Procedure | A measure of the fall in blood pressure in the arteries supplying the legs and is used to detect evidence of blockages in the peripheral vessels. It is calculated by dividing the higher systolic blood pressure in the ankle (dorsalis pedis or posterior tibial) of the one leg by the higher of the two systolic blood pressures in the arms. ABI=Highest Ankle Systolic Pressure/Highest Brachial Systolic Pressure. The ABI is the ratio of the ankle to arm pressure, and an ABI between 0.9 and 1.3 is considered normal. A reduced ABI (less than 0.9) is consistent with peripheral artery occlusive disease, with values below 0.8 indicating moderate disease and below 0.5 severe disease. A value greater than 1.3 is considered abnormal suggesting calcification of the walls of the arteries and noncompressible vessels, reflecting severe peripheral vascular disease. For patients in whom the ABI cannot be accurately measured , toe pressure measurement and toe brachial index should be used. |
| Clinically-driven Target Lesion Revascularization (CD-TLR) | At 1 month | Revascularization within the borders of the stent, +5 mm unstented vessel at both ends, with diameter stenosis ≥ 50% (determined by duplex ultrasound or angiographic core laboratory) (Note: This does not include coincidental overlap of a percutaneous transluminal angioplasty (PTA) balloon or stent into a study stent, that has \<50% stenosis, while treating a non-target lesion in the target vessel) plus one or both of the following: * Worsening Rutherford-Becker Clinical Category; * Change in ABI by \>0.15 and ABI ≤0.8 |
| Any Target Lesion Revascularization (TLR) | At 1 month | TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion.

The target lesion is defined as the treated segment from 5 mm proximal to the stent and to 5 mm distal to the stent. |
| Target Vessel Revascularization (TVR) | At 1 month | TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The target vessel is defined as the ipsilateral superficial femoral artery and the proximal popliteal artery, including the target lesion itself. |

For this trial, the definition of amputation will only include amputations of the limb that was treated. A minor amputation will be defined as below the ankle; a major amputation will be defined as at or above the ankle. |

| Rutherford-Becker Clinical Category for the Treated Limb | Pre-procedure | The Rutherford Becker clinical category is a scale to measure chronic limb ischemia. Category and Clinical Description: 0 = Asymptomatic, no hemodynamically significant occlusive disease, 1 = Mild claudication, 2 = Moderate claudication, 3 = Severe claudication, 4 = Ischemic rest pain, 5 = Minor tissue loss, non-healing ulcer, or focal gangrene with diffuse pedal ischemia, 6 = Major tissue loss, extending above transmetatarsal level, functional foot no longer salvageable. |

It is a measure of subject-perceived walking performance for subjects with Peripheral Artery Disease (PAD) and/or intermittent claudication. The WIQ quantifies patient-reported walking speed, walking distance, and stair-climbing ability, respectively, on a scale of 0 (= worst) to 100 (= best). The highest possible score for each domain is 100%, which indicates no difficulty. Lowest possible score for each domain is 0%, which indicates inability to perform the activity. |

Ankle Brachial Index (ABI) for the Treated Limb
A measure of the fall in blood pressure in the arteries supplying the legs and is used to detect evidence of blockages in the peripheral vessels. It is calculated by dividing the higher systolic blood pressure in the ankle (dorsalis pedis or posterior tibial) of the one leg by the higher of the two systolic blood pressures in the arms. ABI=Highest Ankle Systolic Pressure/Highest Brachial Systolic Pressure. The ABI is the ratio of the ankle to arm pressure, and an ABI between 0.9 and 1.3 is considered normal. A reduced ABI (less than 0.9) is consistent with peripheral artery occlusive disease, with values below 0.8 indicating moderate disease and below 0.5 severe disease. A value greater than 1.3 is considered abnormal suggesting calcification of the walls of the arteries and noncompressible vessels, reflecting severe peripheral vascular disease. For patients in whom the ABI cannot be accurately measured , toe pressure measurement and toe brachial index should be used.
Time frame: Pre-Procedure
Population: ITT population, per subject analysis. The number of participants analyzed includes the subjects with available follow-up data at that time-point. ABI \> 1.3 was excluded from the analysis.

TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. All TLR should be prospectively classified as clinically-driven or not clinically-driven by the investigator prior to repeat angiography.

Vascular Quality of Life (VascuQol) Total Scores
Vascular Quality of Life (VascuQol) : A standardized, validated questionnaire used to evaluate vascular disease-specific health outcomes. VascuQol total score includes scores of Activity Domain, Symptom Domain, Pain Domain, Emotional Domain and Social Domain. Each item is rated as a 7 point response scale, with a score of 1 being the worst and a score of 7 the best possible. The total average score is the sum of all 25 items scores divided by 25. For each separate domain an average score can be calculated (sum of all items of one domain divided by the number of items of that domain). The highest score for each domain is 7, which indicates best health outcome. There are no sub scales.

Walking Impairment Questionnaire Scores
Measured by the Walking Impairment Questionnaire (WIQ), a disease-specific instrument utilized to characterize walking ability through a questionnaire as an alternative to treadmill testing. It is a measure of subject-perceived walking performance for subjects with Peripheral Artery Disease (PAD) and/or intermittent claudication. The WIQ quantifies patient-reported walking speed, walking distance, and stair-climbing ability, respectively, on a scale of 0 (= worst) to 100 (= best). The highest possible score for each domain is 100%, which indicates no difficulty. Lowest possible score for each domain is 0%, which indicates inability to perform the activity.

The highest possible score for each domain is 100%, which indicates no difficulty. Lowest possible score for each domain is 0%, which indicates inability to perform the activity.
Time frame: 12 months
Population: ITT population, per subject analysis. The number of participants analyzed includes the subjects with available follow-up data at that time-point.

Walking Impairment Questionnaire Scores
Measured by the Walking Impairment Questionnaire (WIQ), a disease-specific instrument utilized to characterize walking ability through a questionnaire as an alternative to treadmill testing. It is a measure of subject-perceived walking performance for subjects with Peripheral Artery Disease (PAD) and/or intermittent claudication. The WIQ quantifies patient-reported walking speed, walking distance, and stair-climbing ability, respectively, on a scale of 0 (= worst) to 100 (= best). The highest possible score for each domain is 100%, which indicates no difficulty. Lowest possible score for each domain is 0%, which indicates inability to perform the activity.
