About this study

Official title: Assessment the Safety and Efficacy of Debulking Atherectomy Versus Stent Angioplasty for Limb Ischaemia of Diabetic Lower Limb Atherosclerosis-occlusive Disease: A Multicenter, Randomized, Controlled Study.

In order to assessment the safety and efficacy of debulking atherectomy versus stent angioplasty for limb ischaemia of diabetic lower limb atherosclerosis-occlusive disease, we intend to conduct a prospective, multicenter, randomized controlled, non-inferiority trial. The main surgical methods included stent angioplasty group (Nickel-titanium self-expanding bare stent) and debulking atherectomy group (Excimer laser atherectomy combined with drug-coated balloon angioplasty). The sample size was 244 patients, and the patients were followed up at 30 days, 180 days, and 365 days after operation.

What is being measured

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

  1. Clinical-driven revascularization rate of target lesions 12-months after surgery

    Clinically driven revascularization of target lesions was defined as a reduction of ABI ≥20% or >0.15 due to clinical symptoms or compared to the ABI after the initial surgery, any re-interventional therapy required for the target lesion.

    Measured: 12 months

Secondary outcomes (8)
  1. Technical success

    Intraoperative angiography will demonstrated residual stenosis of the treated vessel <30%

    Measured: Intraoperative

  2. Primary patency rate in patients with claudication (Rutherford grades 1-3) 12 -months after surgery

    Primary patency was defined as peak systolic velocity ratio (PSVR) ≤2.4 (stenosis ≤50%) at 12-month follow-up.

    Measured: 12 months

  3. The rate of unexpected major amputations 12 months after surgery in patients with severe ischemia (Rutherford grades 4-6)

    The rate of unexpected major amputations 12 months after surgery in patients with severe ischemia (Rutherford grades 4-6)

    Measured: 12 months

  4. Wagnar grade changes of diabetic foot ulcers at 6 months and 12 months after surgery (Rutherford Grade 4-6)

    Wagnar grade changes diabetic foot ulcers at 6 months and 12 months after surgery (Rutherford Grade 4-6)

    Measured: 6 months and 12 months

  5. Rutherford grades at 6 and 12 months postoperatively

    Rutherford grades at 6 and 12 months postoperatively

    Measured: 6 months and 12 months

  6. Changes in ankle-brachial index (ABI) at 6 and 12 months after surgery

    Changes in ankle-brachial index (ABI) at 6 and 12 months after surgery

    Measured: 6 months and 12 months

  7. The number of days of hospitalization

    The number of days of hospitalization

    Measured: 1 month

  8. The cost of hospitalization

    The cost of hospitalization

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A study testing Debulking Atherectomy and Stent Angioplasty in people with Peripheral Arterial Disease, run by Xuanwu Hospital, Beijing at 10 sites 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 8 inclusion and 21 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 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites 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.

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 Yongquan Gu, MD (+8615901598209, gu15901598209@aliyun.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical-driven revascularization rate of target lesions 12-months after surgery (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Jan 2023.
