Interventions
Device: Drug-Coated Balloon (DCB)
Registration Number
NCT01566461
Lead Sponsor
Medtronic Endovascular
Brief Summary

The purpose of the study is to demonstrate the safety and efficacy of the IN.PACT Admiral drug-coated balloon (DCB) in comparison to any standard balloon for treatment of peripheral arterial disease (PAD) in the superficial femoral artery and proximal popliteal artery.

Detailed Description

The IN.PACT SFA Trial enrolled in 2 phases: IN.PACT SFA I and IN.PACT SFA II. The 150-patient IN.PACT SFA I phase is intended to support the second phase IN.PACT SFA II IDE trial with congruent design and protocol. Aggregate data from the two phases is intended to provide statistical power for the 12-month primary safety and effectiveness endpoints.

Primary Outcome Measures
NameTimeMethod
Primary Patency12 month

Primary patency is defined as freedom from clinically-driven target lesion revascularisation (CD-TLR) or restenosis as determined by duplex ultrasound (DUS) Peak Systolic Velocity Ratio (PSVR) ≤2.4.

Primary Safety Composite12 month

Primary safety composite is defined as freedom from death through 30 days or target limb major amputation or clinically-driven target vessel revascularization (CD-TVR) within 12 months post index procedure.

Secondary Outcome Measures
NameTimeMethod
Target Vessel Revascularization (TVR)12 month
Thrombosis at the Target Lesion12 month
Major Adverse Event (MAE) Composite12 month

Major Adverse Event (MAE) composite is defined as all cause death, clinically-driven target vessel revascularization, major target limb amputation, thrombosis at the target lesion site.

All-cause Death12 month
Target Lesion Revascularization (TLR)12 month
Major Target Limb Amputation12 month
Time to First Clinically Driven Target Lesion Revascularization (CD-TLR)12 month

Clinically-driven target lesion revascularization (CD-TLR) is defined as any re-intervention within the target lesion due to symptoms or drop of ankle brachial index (ABI) of ≥20% or \>0.15 when compared to post procedure baseline.

Walking Capacity Assessment by Walking Impairment Questionnaire (WIQ)12 month

Walking capacity assessment by WIQ at 1 year compared to baseline. WIQ is a quality of life questionnaire that was specifically designed to assess the degree of impairment experienced by patients with claudication.

Clinical outcomes were assessed by patients responses to question 1A. Question 1A is specific for calf or buttocks claudication and is used to create a summary score for analysis. Question 1A is expressed on a scale of 0% (unable to perform because of severe claudication) to 100% (no impairment).

Device SuccessDay 1

Device success is defined as successful delivery, balloon inflation and deflation and retrieval of the intact study device without burst below rated burst pressure (RBP).

Duplex-defined Binary Restenosis (Peak Systolic Velocity Ratio (PSVR) >3.4)12 month
Primary Sustained Clinical Improvement12 month

Freedom from target limb amputation, target vessel revascularization (TVR), and increase in Rutherford class.

Secondary Sustained Clinical Improvement12 month

Freedom from target amputation and increase in Rutherford class.

Duplex-defined Binary Restenosis (Peak Systolic Velocity Ratio (PSVR) >2.4)12 month
Quality of Life Assessment by EuroQol Group 5-Dimension Self-Report Questionnaire (EQ5D)12 month

Quality of life assessment by EQ5D at 1 year compared to baseline. EQ5D is a standardised measure of health status and economic appraisal. The EQ5D consists of the EQ5D descriptive system which comprises the following variables for the 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: (1) no problems, (2) some problems, (3) extreme problems. A complex algorithm that took individual dimensions and generated an overall score was used.

EQ5D health state is used in the algorithm to calculate an overall score where - 0.109 = 'worst possible outcome' and 1.000 = 'best possible outcome'.

Change in Walking Distance as Assessed by Six Minute Walk Test (6MWT)From baseline to 12 month

Change from baseline in walking distance by Six Minute Walk Test (6MWT) at 12 month.

Procedural SuccessDay 1

Procedural success is defined as residual stenosis of ≤50% (non-stented subjects) or ≤30% (stented subjects) by core lab assessment.

Clinical SuccessDay 1

Clinical success is defined as procedural success without procedural complications (death, major target limb amputation, thrombosis of the target lesion, or Target vessel revascularization (TVR)) prior to discharge.

Days of Hospitalization Due to the Index Lesion12 month

Days of hospitalization from procedure through 12 month.
