Clinical Trial Summary

To demonstrate efficacy and safety of the Lutonix® Drug Coated Balloon for treatment of long TASC II Class C and D lesions (≥ 14 cm) lesions in the SFA

Description:

The study will enroll patients presenting with claudication or ischemic rest pain (Rutherford Category 2-4) and TASC II Class C or D lesions ≥14 cm in length in the native femoropopliteal artery. After successful pre-dilatation (1mm < RVD) and spot stenting (if necessary, with length minimized to mechanical defect), subjects will receive treatment with the Lutonix Drug Coated Balloon (DCB).

The primary safety and efficacy endpoint assessments are performed at 12 months. Clinical follow-up continues through a minimum of 2 years and telephone follow-up through a minimum of 3 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Medical Safety	Combination assessment of freedom from all-cause peri-procedural (=30 day) death and freedom at 1 year from the following: index limb amputation (above or below the ankle) and index limb re-intervention. Success is freedom from all specified events; failure is one or more specified events occurs.	12 Months
Primary	Primary Endpoint Efficacy, measured by presence of primary patency of the target lesion. Patency is assessed by a Corelab based on ultrasound images	Primary Patency is defined as Freedom from Clinically-Driven Target Lesion Revascularization and from Binary Restenosis. Binary restenosis is adjudicated by the independent, blinded core laboratory based on threshold Doppler PSVR = 2.5 (together with wafeform analysis & color mosaic appearance) or based on angiographic = 50% diameter stenosis (if angiography is performed although not required per protocol). Clinically-Driven TLR is adjudicated by the Clincal Events Committee.	12 Months
Secondary	Secondary Endpoint Medical Safety: Major vascular complications	Major vascular complications will be counted: Haematoma at access site >5 cm; False aneurysm; AV fistula; Retroperitoneal bleed; Peripheral ischemia/nerve injury; Any transfusion required will be reported as a vascular complication unless clinical indication clearly other than catheterization complication; Vascular surgical repair	=30 days after index procedure
Secondary	Secondary Endpoint Medical Safety: Composite Safety	Combination assessment of freedom from all-cause death and freedom from the following: index limb amputation (above or below the ankle) and index limb re-intervention. Success is freedom from all specified events; failure is one or more specified events occurs.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Medical Safety: All-cause death	Death by any cause will be counted.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Medical Safety: Major amputation at target limb	Amputations above the ankle of the target leg will be counted.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Medical Safety: Minor amputation at target limb	Amputations below the ankle of the target leg will be counted.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Medical Safety: Target Vessel Revascularization (TVR)	Repeat intervention at the target vessel will be counted.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Medical Safety: Target Limb Reintervention	Repeat intervention at the target leg will be counted.	1, 6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Efficacy: Acute Device Success	Device success is defined as, a per device basis, the achievement of successful delivery and deployment of the study device(s) as intended at the intended target lesion, without balloon rupture or inflation/deflation abnormalities and a successful withdrawal of the study system. If a device is inserted into the subject but not used due to user error (e.g. inappropriate balloon length or transit time too long), this device will not be included in the device success assessment.	During index procedure
Secondary	Secondary Endpoint Efficacy: Technical Success	Technical Success of the balloon procedure is defined as successful access and deployment of the device and visual estimate of = 30% diameter residual stenosis during the index procedure.	During index procedure
Secondary	Secondary Endpoint Efficacy: Procedural Success	Attainment of = 30% residual stenosis in the treatment area by independent core lab analysis without major adverse events (defined as occurrence of death, major amputation of the target limb, target vessel or distal revascularization) during the index procedure and through the hospital stay.	Until index hospitalization discharge
Secondary	Secondary Endpoint Efficacy: Primary Patency	Primary Patency is defined as Freedom from Clinically-Driven Target Lesion Revascularization and from Binary Restenosis. Binary restenosis is adjudicated by the independent, blinded core laboratory based on threshold Doppler PSVR = 2.5 (together with waveform analysis & color mosaic appearance) or based on angiographic = 50% diameter stenosis (if angiography is performed although not required per protocol). Clinically-Driven Target Lesion Revascularization is adjudicated by the Clinical Evenbts Committee.	6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Efficacy: Secondary Patency	Secondary Patency of the target lesion is defined as the absence of binary restenosis as adjudicated by the blinded, independent core laboratory, independent of whether or not patency is re-established via an endovascular procedure.	6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Efficacy: Clinically-driven Target Lesion Revascularization (TLR)	Revascularization of the target vessel with evidence of diameter stenosis >50% determined by duplex ultrasound or angiography and new distal ischemic signs (worsening ABI or worsening Rutherford Category associated with the target limb or due to clinical symptoms) OR revascularization of a target vessel with an in-lesion diameter stenosis of >70% by angiography, in the absence of the previously mentioned ischemic signs or symptoms.	6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Efficacy: Target Lesion Revascularization (TLR)	A repeat revascularization procedure (percutaneous or surgical) of the original target lesion site.	6, 12, 24, 36 months after index procedure
Secondary	Secondary Endpoint Efficacy: Change of Rutherford classification from baseline	Patients are enrolled with a Rutherford grade of 2-4 for their target leg. The Rutherford scale is an indicator for the severity of Peripheral Vascular Disease: 0 = no symptoms, 6 = functional foot is no longer salvageable (leading to foot amputation).	6, 12, 24 months after index procedure
Secondary	Secondary Endpoint Efficacy: Change of resting Ankle Brachial Index (ABI) from baseline	The ABI values will be recorded and compared to the baseline values. The ABI is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm. A ratio of 0.9-1.3 is in the normal range. Lower ratios indicate bad blood perfusion of the leg.	6, 12, 24 months after index procedure
Secondary	Secondary Endpoint Efficacy: Change in Walking Impairment Questionnaire from baseline	The Walking Impairment Questionnaire values will be recorded and compared to the baseline values.; This questionnaire is a validated tool to assess walking capability in patients with Peripheral Arterial Disease in different situations. Worst possible score in this study would be 0, best possible score would be 92.	6, 12, 24 months after index procedure
Secondary	Secondary Endpoint Efficacy: Change in quality of life from baseline, as measured by EQ-5D	The EQ-5D Questionnaire values will be recorded and compared to the baseline values.; It is a validated questionnaire to measure the quality of life based on 5 different paremeters. Worst possible score in this study would be 0, best possible score would be 1. In addition the patient indicates her/his current health on an analog scale from 0 (worst) to 100 (best).	6, 12, 24 months after index procedure
