About this study

Official title: A Prospective, Multicenter, Randomized Trial in Evaluating the Safety and Efficacy of the Paclitaxel Drug-coated Coronary Artery Balloon Catheter in Patients With Coronary Artery In-stent Restenosis Compared to SeQuent® Please Paclitaxel Drug-coated Coronary Artery Balloon Catheter

This study is a multicenter, randomized, controlled clinical research and aims to evaluate the safety and efficacy of the paclitaxel drug-coated coronary artery balloon catheter in patients with coronary artery in-stent restenosis compared to seQuent® please paclitaxel drug-coated coronary artery balloon catheter.

Read the detailed description

This prospective, multicenter, randomized controlled clinical study is designed to enroll 216 subjects with in-stent restenosis and randomly assign them to the trial and control groups on a 1:1 basis.The experimental group was treated with paclitaxel drug-coated coronary artery balloon catheter, and the control group was treated with SeQuent ® Please paclitaxel balloon catheter, which has been marketed. In-segment late lumen loss 9 months after surgery was the main end point of the study. All subjects were followed up clinically at 1 month, 6 months, 9 months, 1 year and 2 years after the surgery, and were followed up with angiography at 9 months after the surgery.

What is being measured

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

  1. In-segment Late Lumen Loss

    In-segment Late Lumen Loss

    Measured: 9 months after coronary angiography

Secondary outcomes (12)
  1. Device success

    defined as residual stenosis ≤30% and TIMI3 blood flow after drug-eluting balloon dilation.

    Measured: during the procedure

  2. Procedural success

    Defined as target lesions with residual stenosis ≤30% and TIMI3 blood flow after any interventional treatment, without thrombus or dissection need interention.

    Measured: Immediately after the index procedure

  3. Clinical success

    Defined as the absence of device-related composite endpoint events during hospitalization (up to 7 days after surgery) on the basis of procedural success.

    Measured: At time of procedure up to 7 days in hospital

  4. Device-oriented composite endpoints (Target Lesion Failure)

    TLF is defined as the composited endpoints of cardiac death, target vessel myocardial infarction and ischemia-driven target lesion revascularization.

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  5. Patient-oriented composite endpoint (PoCE)

    Patient-oriented composite endpoint is defined as all cause death, all myocardial infarction, and any revascularization.

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  6. Death (Cardiac, Non-cardiac)

    Defined as death due to the following causes. Acute myocardial infarction; cardiac perforation/cardiac tamponade; arrhythmia or abnormal conduction; death due to surgical complications, including bleeding, vascular repair, transfusion response, or coronary artery bypass surgery; anything that does not rule out death from cardiac causes.

    Non-cardiac death: defined as death from causes other than the above cardiac causes.

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  7. The number and rate of Myocardial Infarction (MI)

    Attributable to target vessel (TV-MI), Not attributable to target vessel (NTV-MI)

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  8. The number and rate of Target Lesion Revascularization (TLR)

    Ischemia-driven TLR (ID-TLR), Not ischemia-driven TLR (NID-TLR)

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  9. The number and rate of Target Vessel Revascularization (TVR)

    Ischemia-driven TVR (ID-TVR), Not ischemia-driven TVR (NID-TVR)

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  10. The number and rate of Any Revascularization

    Ischemia-driven , Not ischemia-driven

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  11. The number and rate of Thrombosis (per ARC definition)

    Timing (acute, sub-acute, late and very late) Evidence (Definite and Probable)

    Measured: 1 month, 6 months, 9 months, 1 year and 2 years after index procedure

  12. In-segment angiography binary restenosis (ABR, %)

    Defined as the proportion of subjects with restenosis occurring in the target lesion segment and the diameter stenosis ≥50%.Quantitative coronary angiography analysis (QCA) calculation (1- 9 months after the operation of the original stent restenosis in-segment residual minimum lumen diameter / reference vessel diameter) ×100%

    Measured: 9 months after index procedure

Questions about this trial

What is this clinical trial studying?

A study testing coronary artery in-stent restenosis in people with Coronary Artery In-stent Restenosis, run by Shanghai MicroPort Medical (Group) Co., Ltd..

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 7 inclusion and 22 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 2020. Status can change between updates, so confirm with the study contact before making plans.

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 Ling Tao (13636498543, clfeng@microport.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In-segment Late Lumen Loss (time frame: 9 months after coronary angiography). 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 13 May 2020.
