Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Outcomes

Eligibility
Key inclusion criteria
1. The subject has provided written informed consent
2. The subject is willing to participate in the clinical investigation and to comply with the study procedures and follow-up visits
3. Lifestyle-limiting claudication or rest pain requiring treatment of superficial femoral (SFA) and/or proximal popliteal artery (PPA)
4. Age = 18 years old
5. Rutherford-Becker Clinical Category of 2, 3 or 4
6. Target vessel reference diameter =5 mm and = 6 mm (by visual estimation)
7. De novo lesion with >50% stenosis by operator visual estimate within the SFA and/or proximal popliteal arteries in a single limb.
8. Lesion must be located = 1 cm below the Common Femoral Artery (CFA) bifurcation and terminate distally at = 3 cm proximal to the knee joint (radiographic joint space).
9. Single lesion length =170 mm for de novo stenotic lesions, or = 100 mm for occluded lesions (one long lesion or multiple serial lesions) by operator visual estimate. Notes: (1) Only 1 lesion per patient can be treated. Multiple serial lesions are allowed if they can be treated as a single lesion with a maximum of 2 balloons. (2) a non-occlusive lesion that includes a totally occluded segment along its length are eligible provided that the overall treated lesion length is =170 mm (with / or without an occluded segment not greater than 100 mm in length).
10. Successful guidewire crossing of lesion.
11. After pre-dilatation, the target lesion is = 30% residual stenosis with no flow limiting dissection and treatable with a maximum of 2 balloons.
12. Inflow artery is patent, free from significant lesion stenosis (>50% stenosis considered significant) as confirmed by angiography.

Note: Where required, inflow iliac arteries (common and external iliac arteries only) must be successfully treated during the index procedure. Completion angiography must confirm successful treatment of inflow disease (=50% residual stenosis, no distal embolization, and no Grade C or greater dissection) prior to pre-dilatation of the target lesion. Drug-eluting devices are not allowed for treatment of the occluded inflow iliac arteries.
13. Patency of the popliteal segments P2 and P3 with at least 1 patent infrapopliteal run-off vessel (that may have a stenosis of less than 50% not interfering with the outflow to the pedal arch) to the ankle in continuity with the native femoropopliteal artery, in the target limb confirmed at baseline. (Note: treatment of outflow disease is permitted. Drug-eluting devices are not allowed for outflow treatment)
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Females who are pregnant, lactating, or intended to become pregnant, or males intending to father children during the study
2. Subject under current medication known to affect CYP3A4 metabolism, or consuming food or beverages that are known substrates of CYP3A4
3. Contraindication to dual anti-platelet therapy
4. Subject receiving chronic anticoagulation therapy (e.g. low molecular weight heparin, warfarin, or novel direct oral anticoagulants (N(D)OACs)) if the treatment cannot be interrupted 48 hours prior to the procedure
5. Known intolerance to study medications, Limus- like drug or contrast agents that in the opinion of the investigator could not be adequately pretreated
6. Current participation in an investigational drug or another device study
7. History of hemorrhagic stroke within 3 months
8. Patients with a history of Myocardial Infarction (MI) or thrombolysis within 30 days prior-index procedure
9. Previous or planned surgical or interventional procedure within 14 days before or 30 days after index procedure (successful treatment of the ipsilateral and contralateral iliac arteries is permitted during the index procedure. Drug-eluting devices are not allowed for treatment of the occluded inflow iliac arteries)
10. Prior endovascular treatment of the target lesion (e.g., POBA, DCB, BMS, DES, cutting balloons, scoring balloons, cryoplasty, thrombectomy, atherectomy, brachytherapy or laser devices)
11. Previous placement of a bypass graft proximal to the target lesion
12. Chronic renal insufficiency (eGFR < 30 mL/min within 72 hours prior to index procedure)
13. Patient requiring renal replacement therapy
14. No normal proximal arterial segment in which duplex ultrasound velocity ratios could be measured.
15. Subject is unable to walk without assistance (e.g. walker, cane).
16. Subject is receiving immunosuppressant therapy.
17. Subject has known or suspected active infection at the time of the index procedure.
18. Subject has platelet count < 100,000/mm3 or > 700,000/mm3.
19. Subject has white blood cell (WBC) count < 3,000/mm3.
20. Subject is unable to tolerate blood transfusions because of religious beliefs or other reasons.
21. Subject has history of gastrointestinal hemorrhage requiring a transfusion within 3 months prior to the index procedure.
22. Life expectancy less than 12 months due to other comorbidities, that in the investigators opinion, could limit subject ability to comply with the study required follow-up visits/procedure and threaten the study scientific integrity
23. Treatment of the contralateral limb during the same procedure or within 30 days following the study procedure (exclusive of the iliac arteries, which can be treated during the index procedure if no drug eluting technology is used)
24. Non femoral vascular access
25. Target lesion would require treatment with more than two BRight balloons
26. Known inadequate distal outflow
27. Acute or sub-acute thrombus in the target vessel
28. Aneurysmal target vessel
29. Use of adjunctive therapies (i.e. laser, atherectomy, cryoplasty, scoring/cutting balloon, brachytherapy) during the study procedure in the target lesion or target vessel
30. Presence of concentric calcification that precludes PTA pre-dilatation
31. Significant contralateral or ipsilateral common femoral disease that requires intervention during the index procedure
32. Persistent hemodynamically-significant stenosis following predilatation or residual stenosis of >30%, stent placement, or flow-limiting (Grade D or greater) dissection following pre-dilatation
33. In-stent restenosis

Summary
Brief summary
The BRight PK Study is a prospective, single-arm, open-label, non-blinded, non-randomized study, which goal is to assess the pharmacokinetic profile of the BRight drug-coated balloon at different time points after the balloon deployment.

The study will enroll a maximum of 10 patients at a single site in Australia
