About this study

Official title: A Prospective, Multi-center, Randomized Study to Evaluate the Safety and Efficacy of DK ScoreTM Scoring Balloon Vesus Non-Slip Element Coronary Dilatation Catheter for Coronary Artery Stenosis

A prospective, Multi-center, Randomized Study designed to evaluate the acute lumen gain and device procedural success of the DK ScoreTM Scoring balloon versus NSE Scoring Balloon for patients with coronary arteries stenosis.

Read the detailed description

This is a prospective, multi-center, randomized controlled, open-label, noninferior study to evaluate Acute Lumen Gain after dilatation. A total of 200 patients will be enrolled from 4 sites in China. All patients enrolled will be randomly assigned to the test group (DK ScoreTM group, n=100) and the control group (NSE group, n=100) with randomized allocation ratio of 1:1. Patients in the test group and the control group will be treated with DK ScoreTM Scoring balloon catheters or NSE Coronary Dilatation Catheter. A 30-day after procedure follow-up will be conducted for all 200 patients.

What participants receive

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

  • DK ScoreTM Coronary Scoring BalloonDevice

    Also called DK Score

    After pre-dilation balloon is used (if any), DK Score is used as final dilatation balloon before Drug Eluting Stent implantation or Drug Coated Balloon deployment.

  • Non-Slip Element Coronary Dilatation CatheterDevice

    Also called NSE

    After pre-dilation balloon is used (if any), NSE is used as final dilatation balloon before Drug Eluting Stent implantation or Drug Coated Balloon deployment.

What is being measured

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

  1. Numerical Acute Lumen Gain in mm (QCA)

    Acute Lumen Gain for both arms will be measure with QCA, as accessed by independent core-lab.

    Angiographic endpoint will be in-lesion acute lumen gain defined as minimal lumen diameter (MLD) in lumen after dilatation by either arm device minus baseline MLD.

    Measured: During the procedure

Secondary outcomes (5)
  1. Rate of Device success in percent

    Successful delivery to the target lesion, deployment, achieving less than 50% residual stenosis, and retrieval after procedure.

    Measured: During the procedure

  2. Rate of Target Lesion Failure in percent

    Defined as any Target Lesion Failure after procedure

    Measured: 30±7 Days

  3. Rate of Patient-oriented Composite Endpoint (POCE) in percent

    Patient-oriented Composite Endpoint after procedure

    Measured: 30±7 Days

  4. Rate of other Complications in percent

    Incidence of complications associated with the use of scoring balloon catheters

    Measured: During the procedure

  5. Rate of Clinical Success in percent

    Defined as <20% diameter stenosis after stenting for DCB, without in-hospital major adverse cardiac events/MI/TLR After PCI

    Measured: During the procedure

Questions about this trial

What is this clinical trial studying?

A study testing DK ScoreTM Coronary Scoring Balloon and Non-Slip Element Coronary Dilatation Catheter in people with Coronary Stenosis, run by DK Medical Technology (Suzhou) Co., Ltd. at 4 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 18 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: finished, as of the sponsor's last update on 10 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numerical Acute Lumen Gain in mm (QCA) (time frame: During the procedure). 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 10 Mar 2022.
