Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
264

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Test group
Intervention: Medeliver® Intracranial Drug-Coated Balloon Catheter Manufacturer: Beijing JSSK Neuro Medical Co., Ltd.
Device: Intracranial Drug-Coated Balloon Catheter (Medeliver®)
The Medeliver® intracranial drug-coated balloon dilatation catheter is indicated for interventional treatment of symptomatic intracranial atherosclerotic stenosis lesions. It restores the original vascular lumen through balloon dilatation of the stenotic segment while simultaneously delivering an anti-proliferative agent (sirolimus/rapamycin) coated on the balloon surface to the lesion site.
Active Comparator: Control Group
Intervention: Diveroad® Intracranial Balloon Dilatation Catheter Manufacturer: Beijing JSSK Neuro Medical Co., Ltd.
Device: Intracranial Balloon Dilatation Catheter (Diveroad®)
The Diveroad® intracranial balloon dilatation catheter is indicated for interventional treatment of symptomatic intracranial atherosclerotic stenosis lesions. It restores the original vascular lumen through balloon dilatation of the stenotic segment.

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
Time Frame
The 12-month post-procedural rates of target lesion restenosis, stroke recurrence or mortality in the territory of the target vessel.
Time Frame: From enrollment to the end of follow-up at 12 months
From enrollment to the end of follow-up at 12 months
