Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Advance Scoring Balloon is a balloon catheter used to perform angioplasty in narrowed blood vessels. In this study it is used to treat narrowing of a hemodialysis fistula in order to improve the effectiveness of dialysis. Angiography and intravascular ultrasound will be used during the procedure to examine the effectiveness of the study procedure. The procedure should take approximately 45 minutes. After the procedure, participants are required to complete follow-up visits at 1, 3, and 6 months to undergo clinical assessment. An angiogram will also be performed at 3 and 6 months post-procedure.

No comparator/control treatment.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 290543 0
Procedural peformance of the device, specifically:
1. Extent of residual stenosis (less than 30 %) within the treated lesion immediately after angioplasty, assessed by angiography
2. Inflation pressure of scoring balloon, measured using a balloon inflation device with atmospheric pressure guage
3. Adverse events, e.g. aneurysm; vessel dissection, perforation, rupture or injury; pain and/or discomfort at stenosis during treatment; hematoma
Timepoint [1] 290543 0
Throughout the duration of the procedure and immediately after the procedure.
Primary outcome [2] 290544 0
Short term perfomance of the device assessed by resumption of normal dialysis and target lesion patency at 6 months post-procedure.
Resumption of normal dialysis will be assessed by obtaining dialysis treatment information on the patient following the study procedure.
Target lesion patency will be assessed based on continued successful dialysis treatment, need for re-intervention or abandonment of access site, and angiography at 6 months.
Timepoint [2] 290544 0
6 months post-procedure
Secondary outcome [1] 304846 0
Short term perfomance of the device assessed by target lesion patency at 1 and 3 months post-procedure.
Target lesion patency will be assessed based on continued successful dialysis treatment, need for re-intervention or abandonment of access site, and angiography at 3 months (angiography not performed at 1 month).
Timepoint [1] 304846 0
1 and 3 months post-procedure

Eligibility

4. Known hypersensitivity or contraindication to contrast agent that, in the opinion of the investigator, cannot be adequately pre-medicated
5. Synthetic AV dialysis access graft
6. Current or previous history of thrombosis anywhere within the AV dialysis access circuit
7. Evidence of systemic or local infection associated with the AV dialysis access circuit
8. History of bleeding diathesis or coagulopathy or will refuse blood transfusions
9. Stent or stent graft in the AV dialysis access circuit
10. Hemodynamically significant central venous stenosis, unless successfully treated prior to treating the study lesion
11. Presence of occlusion in the AV dialysis access circuit such that a guidewire cannot pass through the lesion
12. Target lesion is greater than or equal to 4 cm in length
13. Reference vessel diameter is greater than 12 mm
14. Presence of more than two distinct lesions (stenoses) in the AV dialysis access circuit
