Brief Summary:
The Chocolate Touch study is a randomized, multi-center, prospective, adaptive study, designed to show sufficient safety and effectiveness of the Chocolate Touch™ for use in superficial femoral or popliteal arteries with the intention of obtaining regulatory approval to market this device in the United States

Condition or disease Intervention/treatment Phase
Intermittent Claudication Ischemia Device: Chocolate Touch Device: Lutonix Drug Coated Balloon Not Applicable

Detailed Description:

The primary objective of the Chocolate Touch study is to demonstrate non-inferior safety and non-inferior effectiveness of the Chocolate Touch™ compared to the Lutonix® drug coated balloon catheter. These data are intended to show safety and effectiveness of the Chocolate Touch sufficient to support regulatory approval to market this device in the United States for use in superficial femoral or popliteal arteries.

Study success is defined as statistical demonstration of the non-inferiority hypothesis tests for both the primary safety and effectiveness hypothesis.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 585 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: A Randomized Trial to Confirm the Safety and Effectiveness of Chocolate Touch™ Paclitaxel Coated Balloon Catheter, in Above the Knee Lesions
Actual Study Start Date : July 26, 2017
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2022

Drug Information available for: Paclitaxel

Arm Intervention/treatment
Experimental: Test Group (Chocolate Touch)
  • The diameter of the Chocolate Touch should correspond to the diameter of the vessel for treatment with a balloon to artery ratio of 1.1:1.
  • The Chocolate Touch must be inflated to at least nominal pressure. Maintain balloon inflation for a minimum of 2 minutes. The balloon may be inflated as long as required to achieve optimal angioplasty outcome.
  • If delivery is attempted and failed, a new Chocolate Touch should be used for subsequent attempts after pre-dilatation.
Device: Chocolate Touch
The Chocolate Touch™ Paclitaxel Coated Balloon Catheter is indicated for balloon dilatation, after appropriate vessel preparation as needed, of lesions in native superficial femoral or popliteal arteries up to 15 cm in length that are appropriate for angioplasty with balloon diameters from 3.5 mm to 6.0mm.
Other Name: Chocolate Touch™ Paclitaxel Coated Balloon Catheter

Active Comparator: Control Group (Lutonix Drug Coated Balloon)
  • Never inflate the Lutonix® Drug Coated Balloon (DCB)prior to reaching the target lesion.
  • The Lutonix® Catheter should be advanced to the target site as fast as possible (i.e. 30 seconds) and immediately inflated to appropriate pressure to ensure full wall apposition (balloon to artery ratio of >1:1).
  • If the deployment of the Lutonix® Catheter exceeds 3 minutes, the catheter requires placement with a new unit.
  • Maintain balloon inflation for a minimum of 2 minutes (120 seconds). The balloon may be inflated as long as required by standard of care to achieve a good angioplasty outcome.
Device: Lutonix Drug Coated Balloon
The Lutonix® 035 Drug Coated Balloon Catheter is indicated for improving luminal diameter for the treatment of obstructive de novo or non-stented restenotic lesions (≤ 15 cm in length) in native femoropopliteal arteries having reference vessel diameters of 4 mm to 6 mm.
Other Name: LUTONIX® 035 Drug Coated Balloon Catheter




Primary Outcome Measures :
  1. True Drug Coated Balloon Success [ Time Frame: 12 months ]
    A composite endpoint that requires patients to achieve Primary Patency (Peak systolic velocity ratio <2.4 without the need for clinically driven target lesion revascularization) in the absence of a clinically driven bail-out stent (core lab adjudicated).

  2. Freedom from Major Adverse Events [ Time Frame: 12 months ]
    Composite of target-limb-related death, major amputation of the target limb, and clinically driven re-intervention of the target limb.


Secondary Outcome Measures :
  1. By Angiographic Core Lab Review (Acute) [ Time Frame: 1 hour ]
    Procedural Success: Defined as the success of the therapy to achieve <30% diameter stenosis without a flow-limiting dissection or the need for a stent

  2. By Duplex Ultrasound Core Lab Review [ Time Frame: 6, 12 & 24 months ]
    Patency

  3. By Clinical Assessment [ Time Frame: 1, 6, 12, & 24 months ]
    Occurrence of relevant Adverse Events
