Coronary Artery Drug-Coated Balloon Dilatation Catheter Clinical Trial Protocol

February 10, 2026 updated by: DK Medical Technology (Suzhou) Co., Ltd.

A Retrospective, Multicenter, Post-marketing Clinical Study to Evaluate the Long-term Efficacy and Safety of Coronary Artery Drug-Coated Balloon Dilatation Catheter in the Treatment of In-Stent Restenosis or De Novo Coronary Artery Lesions

This clinical trial adopts a retrospective, multicenter design with data registered and collected via an Electronic Data Capture (EDC) system. A total of 252 eligible subjects will be enrolled in the trial, who are consecutively selected in accordance with the inclusion and exclusion criteria from 2022 to the end of 2023 in a retrospective manner. Data collection will be conducted at four time points for all enrolled subjects, including the screening period, 6 months (±30 days) after surgery, 12 months (±30 days) after surgery, and 24 months (±60 days) after surgery. Relevant data of retrospective subjects will be obtained by reviewing medical records.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

treatment group
Coronary Artery Drug-Coated Balloon Dilatation Catheter
Device: Coronary Artery Drug-Coated Balloon Dilatation Catheter
subjects who have received coronary artery drug-coated balloon dilatation catheter treatment in the selected centers for a period of time since the product's marketing will be screened one by one in accordance with the inclusion and exclusion criteria. During the process, data collection will be conducted by direct medical history collection or reviewing medical records in the medical record system of each center.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
the incidence of Target Lesion Failure (TLF).
Time Frame: 24 months
The percentage of subjects who experience TLF from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. TLF is defined as a composite endpoint of cardiac death, target vessel myocardial infarction (Q-wave or non-Q-wave MI), and clinically driven target lesion revascularization (CD-TLR).
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Surgical success rate
Time Frame: Immediately after the treatment
The percentage of subjects with successful surgery among the total number of subjects. Surgical success is defined as visual residual stenosis diameter ≤30% at the target lesion after PCI, TIMI flow grade 3 (visual assessment), and no rescue stent implantation required.
Immediately after the treatment
Incidence of stent thrombosis
Time Frame: 24 months
The percentage of subjects with all stent thrombosis events meeting the ARC criteria (including definite and probable) from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects.
24 months
Incidence of device-related cardiovascular events (DoCE)
Time Frame: 24 months
The percentage of subjects with device-related cardiovascular events from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. The device-related clinical composite cardiovascular endpoint is defined as cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization.
24 months
Incidence of patient-related cardiovascular events (PoCE)
Time Frame: 24 months
The percentage of subjects with patient-related cardiovascular events from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. The patient-related clinical composite cardiovascular endpoint is defined as all-cause death, all myocardial infarctions, and any repeat revascularization.
24 months
Device usage
Time Frame: Immediately after the treatment
The average number of investigational devices used per lesion and the adjuvant devices used.
Immediately after the treatment
