Trial summary

Recurrent stenosis in hemodialysis access graft (AVG) is difficult to treat. For recurrent stenosis in the anastomotic junction can be treated by stent graft to improve long-term patency. However, there is no data regarding treatment of stent graft restenosis in AVG. Read more about this study

About this study

Official title: A Randomized Trial Comparing Drug-coated Balloon and Regular Balloon for Dialysis Access Stent Graft Restenosis

Recurrent stenosis in hemodialysis access graft (AVG) is difficult to treat. For recurrent stenosis in the anastomotic junction can be treated by stent graft to improve long-term patency. However, there is no data regarding treatment of stent graft restenosis in AVG. This randomized trial is designed to compare the efficacy and safety of drug-coated balloon (DCB) versus regular balloon in AVG stent graft restenosis.

Read the detailed description

Prosthetic arteriovenous hemodialysis access graft (AVG) has high incidences of venous anastomotic stenosis and access failure. A stent graft can be used in AVG with recurrent venous anastomotic stenosis to improve long-term patency rate. However, after stent graft implementation, the effective treatment for restenosis in a stent graft is still unknown. This randomized trial is designed to evaluate the efficacy and safety of drug-coated balloon versus regular balloon for in-stent restenosis in stent graft. The investigators plan to enroll 40 patients who presented with prosthetic AVG in-stent restenosis, and then to evaluate the restenosis lesions by intravascular ultrasound. Patients will be randomized into two groups of treatment: drug-coated balloon angioplasty or regular balloon angioplasty.

Being tested
Regular balloon, DCB (paclitaxel-coated balloon)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Regular balloonDevice

    Randomization: to use regular balloon to treat stent graft restenosis

  • DCB (paclitaxel-coated balloon)Device

    Randomization: to use DCB (paclitaxel-coated balloon, Ranger, Boston-Scientific) to treat stent graft restenosis. The paclitaxel dose is 2 ug/mm2 delivered with the Ranger drug-coated balloon.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Late luminal loss

    The late luminal loss found by IVUS on follow-up in comparison to index procedure.

    Measured: 0, 1, and 3 months

Secondary outcomes (4)
  1. minimal luminal area and diameter

    Done by IVUS on follow-up in comparison to index procedure.

    Measured: 0, 1, and 3 months

  2. restenosis rate

    Compare with follow-up angiography.

    Measured: 0, 1, and 3 months

  3. repeated intervention

    defined by repeated endovascular balloon angioplasty or endovascular thrombectomy or surgical open thrombectomy.

    Measured: 0, 1, and 3 months

  4. abandon of AV graft, death

    stopped to use the target AVG or mortality

    Measured: 0, 1, and 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Regular balloon and DCB (paclitaxel-coated balloon) in people with Hemodialysis Access Failure (Disorder) and Stent-Graft Restenosis, run by National Taiwan University Hospital Hsin-Chu Branch at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mu-Yang Hsieh, MD (886-35326151 ext. 2009, h11135@hch.gov.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Late luminal loss (time frame: 0, 1, and 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03360279, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Dec 2017.
