Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

PMA P210039 approval has been granted on 11/04/2022. The study is now in the post-approval phase.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Chocolate Touch

Intervention Type DEVICE

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 18 cm in length that are appropriate for angioplasty with balloon diameters from 3.5 mm to 6.0mm.

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.
