To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Interventional
Description of intervention(s) / exposure
Treatment: Devices - Chocolate Touch
Treatment: Devices - Lutonix Drug Coated Balloon

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.

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.


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

Treatment: Devices: 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 (= 18 cm in length) in native femoropopliteal arteries having reference vessel diameters of 4 mm to 6 mm.

Eligibility
Key inclusion criteria
Inclusion Criteria

General:

1. Minimum of 18 years of age
2. Intermittent claudication or ischemic rest pain (Rutherford 2-4)
3. Life Expectancy >2 years
4. Patient has agreed to follow-up requirements and given informed consent

Angiographic:
5. Lesion successfully crossed with a guidewire
6. Lesion in the SFA or popliteal artery defined as a lesion with a proximal origin >10 mm from SFA origin (deep femoral artery) and a distal end above the knee joint (at least 3 cm above bottom of the femur - P1).
7. Target Lesion =70% stenosis in the SFA or popliteal arteries
8. Reference Vessel Diameter (RVD) between 4.0 & 6.0mm and within treatment range of Chocolate Touch to be used 1.1:1 at the Target Lesion
9. Target Lesion =180mm that consists of no more than two adjacent lesions (= 25mm apart) and is able to be completely covered with inflation of no more than two assigned balloons (with minimum of >5mm overlap to the area covered by the first balloon). (Note: Adjacent or tandem target lesions must be treated as a single lesion.)
10. Angiographic evidence of distal run-off demonstrated by at least one patent tibial vessel without evidence of significant (=70%) stenosis from origin to ankle
11. In-flow vessel without significant stenosis (=70%) or successful treatment (=30% residual stenosis with no complications) of a diseased vessel. Note: treatment of contralateral iliac is permissible.

Key exclusion criteria
Exclusion Criteria

General:

1. Acute limb ischemia, or patient indicated for thrombolytic therapy
2. Planned surgical or interventional procedures within 30 days after study procedure.
3. Non-target lesion concurrent interventions involving a re-entry device, atherectomy, laser, or ablation procedures, the use of a drug eluting stent, or, treatment with any other drug coated balloon.
4. Myocardial infarction or stroke within 30 days prior to the procedure
5. Known intolerance to required medications, contrast media that cannot be adequately premedicated, nitinol, or Paclitaxel
6. Known impaired Renal Function that could have an impact on contrast tolerance with GFR = 30 ml/min per 1.73 m2 and/or elevated serum creatinine >2.5mg/dL (220µmol/L) or on dialysis.
7. Known bleeding disorder, or on dialysis, or uncontrolled hypercoagulable disorder
8. Non-atherosclerotic lesion (e.g. vasculitis or Berger's disease)
9. Female who is pregnant or intends to be pregnant during study
10. Patient is enrolled in another investigational clinical study or was previously enrolled in this study

Angiographic:
11. Presence of perforation, dissection (Type D or worse) or other injury in target vessel at time of enrollment
12. Severe Calcification at the target lesion (defined as angiographic evidence of dense calcification present on both sides of the vessel wall on two orthogonal views and that extends >50 continuous mm in length).
13. Previous bypass graft, stent at target vessel (must be greater than 20mm from target lesion), or iliac stent that cannot permit crossing by the treatment balloon within the introducer sheath (Note: In-stent restenosis is not allowed.)
