What is being measured

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

  1. Primary Patency

    Primary patency defined as freedom from clinically driven target lesion revascularization (CD-TLR) and freedom from duplex ultrasound derived binary restenosis at 12 months post-operation.(defined as PSVR >2.5)

    Measured: 12 months post-operation

  2. Freedom from Major Adverse Events (MAEs)

    Freedom from the occurrence of any new-onset MAEs defined as all-cause death, index limb amputation (above the ankle), or clinically-driven target lesion revascularization (CD-TLR) at 30 days post-operation.

    Measured: 30 days post-operation

Secondary outcomes (9)
  1. Rate of Device Success

    Defined as successful delivery, release and retrieval of the device.

    Measured: immediately post-operation

  2. Rate of Procedural Success

    Demonstrated vessel patency (<30% residual DS, by visual estimate) without the use of a bailout stent or the occurrence of MAE upon completion of the index procedure.

    Measured: immediately post-operation

  3. Primary Patency at 30 days and 6 months

    defined as freedom from clinically driven target lesion revascularization (CD-TLR) and freedom from duplex ultrasound derived binary restenosis at 30 days and 6 months post-operation (defined as PSVR >2.5)

    Measured: 30 days and 6 months post-operation

  4. Rate of clinically driven target lesion revascularization (CD-TLR)

    Clinically driven target lesion revascularization (CD-TLR) was defined as an endovascular reintervention performed for a >50% diameter stenosis of the target vessel in the presence of a recurrent PAD symptom after the initial endovascular procedure.

    Measured: 30 days, 6 months and 12 months post-operation

  5. Changes from Baseline in Rutherford Classification

    Defined as change in target limb Rutherford class from baseline. Rutherford Classification is defined as follows, with increasing severity:

    Rutherford Category 0 - Asymptomatic. Rutherford Category 1 - Mild Claudication. Rutherford Category 2 - Moderate Claudication. Rutherford Category 3 - Severe Claudication. Rutherford Category 4 - Ischemic Rest Pain. Rutherford Category 5 - Minor Tissue Loss (minor exertion). Rutherford Category 6 - Major Tissue Loss (gangrene).

    Measured: 30 days, 6 months and 12 months post-operation

  6. Changes from Baseline in Ankle-brachial Index (ABI)

    Defined as change of target limb ABI from baseline. The Ankle Brachial Index (ABI) is the systolic pressure at the ankle, divided by the systolic pressure at the arm.

    Measured: 30 days, 6 months and 12 months post-operation

  7. Duplex Ultrasound (DUS) Derived Lesion Patency

    Lesion Patency is evaluated by Duplex Ultrasound (DUS)

    Measured: 30 days, 6 months and 12 months post-operation

  8. Rate of major adverse event(s) (MAEs)

    MAEs defined as all-cause death, index limb amputation (above the ankle), or clinically-driven target lesion revascularization (CD-TLR) .

    Measured: 6 months and 12 months post-operation

  9. Rate of Stent Fracture

    Stent fractures will be analyzed by X-ray at 12 months post-operation. The stents implanted into a certain subject will be analyzed collectively in the assessment. Stent fractures will be assessed with Grade I, II, III or IV as follow.

    Grade I - a single strut fracture only. Grade II - multiple single strut fractures that occur at different sites of a stent or different stents.

    Grade III - multiple nitinol stent fractures resulting in complete transverse linear fracture.

    Grade IV - a spiral dissection of a stent. Fractures of Grade I are least severe, increasing in severity to Grade IV.

    Measured: 12 months post-operation

Questions about this trial

What is this clinical trial studying?

A study testing Sperstent® peripheral spot stent system and Everflex® self-expanding peripheral stent system in people with Peripheral Arterial Disease and Stenosis, run by FrontAce Scientific Co., Ltd at 12 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 11 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: looking for participants now, as of the sponsor's last update on 6 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Min Zhou, Dr. (01186-25-83106666 ext. 60770, zhouminnju@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Patency (time frame: 12 months post-operation). 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?
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 6 Aug 2024.
