About this study
Official title: The Efficacy and Safety of Paclitaxel-eluting Balloons for the Treatment of Below the Knee Peripheral Arterial Disease as Compared to Conventional Balloon Angioplasty: a Randomized Controlled Clinical Trial.
Comparing the efficacy and safety of drug-eluting balloons (DEB) for the treatment of below-the-knee peripheral arterial occlusive disease with conventional balloon angioplasty (BA).
Read the detailed description
Over the past decade, percutaneous transluminal angioplasty (PTA) has established its position in the treatment of below the knee arterial occlusive disease with intermittent claudication and/or critical limb ischemia. However, the efficacy of percutaneous transluminal angioplasty (PTA) with conventional balloons, is limited by the high 12-month restenosis and target lesion revascularization (TLR) rates. Local delivery of newer anti-proliferative drug via drug-eluting balloons (DEBs) has recently shown promising results in the treatment of femoropopliteal disease, and in the BTK area, a reduction in 3-month binary restenosis has been observed compared with historical controls treated with PTA. Drug eluting balloon has three potential advantages: (1) homogenous drug transfer to the vessel wall; (2) highest drug concentrations at the vessel wall at the time of injury; and (3) absence of a stent or delivery polymer.
This study sought to investigate the long-term efficacy and safety of new drug (Paclitaxel)-eluting balloons (DEB) for the treatment of below the knee peripheral arterial disease.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Drug eluting balloon angioplastyDevice
In the DEB group, the guide wire will be passed through the occluded or stenosed lumen and the predilatation of the target lesion with standard balloon(s) will be performed before dilatation with a paclitaxel-eluting balloon of the diameter, at least about that of the pre-dilatation balloon (Arteryguard, Rientech, Dezhou, China). The drug eluting balloons will then be inflated according to the manufacturer recommendations. The patients will then be followed every six months for a year to compare its treatment efficacy and safety with that of conventional balloon angioplasty group.
Conventional balloon angioplastyDevice
The guide wire will be passed through the occluded or stenosed lumen and the conventional balloons will be inflated as recommended by the manufacturer. The primary and secondary outcome will then be assessed and compared with DEB group, on follow up at six and 12 months.
| Study group | Role | What they receive |
|---|---|---|
| Drug eluting balloon angioplasty | Experimental | Paclitaxel coated balloon angioplasty Receives: Device: Drug eluting balloon angioplasty |
| Conventional balloon angioplasty | Active comparator | Conventional balloon angioplasty Receives: Device: Conventional balloon angioplasty |
What is being measured
The primary outcome is the main question the study is designed to answer.
Restenosis rate
The primary study endpoint was the occurrence of > 50% of restenosis in the treated vessel after 12 months as assessed by digital substraction angiography (DSA).
Measured: 12 months
Peak systolic velocity ratio
Peak systolic velocity ratio ≥ 2.4 by Doppler's ultrasonography was the end point of the study for the patient who did not undergo angiography after 12 months.
Measured: 12 months
Secondary outcomes (3)
Rutherford scale
Clinical success is to be defined as an improvement in Rutherford scale of at least one category after the procedure.
Measured: Immediately after procedure
ABI value
Hemodynamic success is to be defined as an improvement of ABI value by ≥ 0.1 after the procedure and lack of deterioration > 0.15 in relation to the maximal value recorded before the procedure.
Measured: Immediately after procedure
Residual stenosis
The technical success of the procedure is to be defined as PTA of a lesion with >30 % residual stenosis and lack of flow rate-limiting dissection immediately after treatment.
Measured: Immediately after procedure

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Drug eluting balloon angioplasty and Conventional balloon angioplasty in people with Peripheral Arterial Disease, run by Shanghai 10th People's Hospital at 1 site in China.
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 6 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 13 May 2016. 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 China. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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 Maoquan Li, Ph.D (02166313506, cjr.limaoquan@vip.163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Restenosis rate (time frame: 12 months). The study lists 2 primary outcomes in all. 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 NCT02772224, which also lists 5 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 13 May 2016.
