About this study

Official title: A Prospective, Multi-center, Open-label, Controlled, Superiority, Randomized, Controlled Registration Trial of the Rapamycin Target Eluting Stent for the Treatment of Symptomatic Cerebral Artery Atherosclerotic Disease(TARGET-DREAM)

The trial is a prospective, multicenter, open-label, superiority, randomized controlled clinical trial. The experimental groups include two types of drug-eluting stents:

  • Experimental Device A, a self-expanding rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China)
  • Experimental Device B, a balloon-expandable rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China) The device used in the control group is the Apollo® Intracranial Artery Stent System, a balloon-expandable bare-metal stent (MicroPort NeuroTech, Shanghai, China), According to the inclusion and exclusion criteria specified in the protocol, approximately 249 subjects with symptomatic cerebral artery atherosclerotic stenosis will be enrolled in China and randomized to Experimental Group A, Experimental Group B, or the control group.

Considering the broader applicability of Experimental Device A and Experimental Device B compared to the control device, a specification subgroup is established. 20 subjects with lesions only suitable for the unique specifications of Experimental Device A or Experimental Device B will be enrolled in China. These subjects will not undergo randomization, and their data will be analyzed separately without hypothesis testing.

Moreover, a subgroup of Experimental Device B is established at a study center in Brazil. 10 subjects meeting the trial's inclusion and criteria will be enrolled. These subjects will not undergo randomization, and their data will be analyzed separately without hypothesis testing, only to support overseas registration.

Overall, the total sample size for the study is 279 subjects. Clinical assessment will be conducted for all subjects before the procedure, during the procedure, at discharge, at 1 month (±7 days) follow-up, at 6 months (±30 days) follow-up, and at 12 months (±60 days) follow-up. At 12 months (±60 days), patients will undergo follow-up with DSA imaging. Unscheduled follow-ups may be performed as needed to record relevant indicators and evaluate the safety and efficacy of the two drug-eluting stents in the treatment of symptomatic cerebral artery atherosclerotic stenosis.

Experimental Device A, a self-expanding rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China), Experimental Device B, a balloon-expandable rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China), Apollo® Intracranial Artery Stent System, a balloon-expandable bare-metal stent (MicroPort NeuroTech, Shanghai, China),

What is being measured

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

  1. In-stent restenosis (ISR) rate at 12 months post-procedure

    ISR is defined as >50% stenosis within or adjacent (within 5 mm) to the stent as well as >20% absolute luminal loss according to the WASID method diagnosed by DSA

    Measured: 12 months after surgery(±60days)

Secondary outcomes (7)
  1. Technical success rate of stent implantation

    defined as successful implantation into qualifying lesion as well as successful retraction of delivery system

    Measured: Day 0(within 1hour after procedure)

  2. Symptomatic ISR rate at 12 months post-procedure

    ISR (ISR is defined as >50% stenosis within or adjacent (within 5 mm) to the stent as well as >20% absolute luminal loss according to the WASID method diagnosed by DSA) occurs with ischemic stroke or TIA from target lesion restenosis.

    Stroke is defined as acute focal/systemic neurological dysfunction from brain/spinal cord/retinal vascular occlusion, stenosis, or injury - induced hemorrhage/infarction.

    TIA is defined as transient focal neurological dysfunction from brain/spinal cord/retinal ischemia, with symptoms lasting<24 hours and no acute infarction.

    Measured: 12 months after surgery(±60days)

  3. Revascularization rate from qualifying artery at 12 months post-procedure

    During follow-up, revascularization procedures (including interventional thrombectomy, angioplasty, vascular bypass, etc.) due to ischemic stroke or TIA from target lesions.

    Stroke is defined as acute focal/systemic neurological dysfunction from brain/spinal cord/retinal vascular occlusion, stenosis, or injury - induced hemorrhage/infarction.

    TIA is defined as transient focal neurological dysfunction from brain/spinal cord/retinal ischemia, with symptoms lasting<24 hours and no acute infarction.

    Measured: During the days of follow-up(up to 12month ±60 days)

  4. Modified Rankin Scale (mRS) score at 12 months post-procedure

    Measured: 12 months after surgery(±60days)

  5. Stroke or death related to qualifying lesion at 30 days, 6 months, and 12 months post-procedure

    Stroke is defined as acute focal/systemic neurological dysfunction from brain/spinal cord/retinal vascular occlusion, stenosis, or injury - induced hemorrhage/infarction.

    Measured: During the days of follow-up(up to 12month ±60 days)

  6. Any stroke or death at 30 days, 6 months, and 12 months post-procedure

    Stroke is defined as acute focal/systemic neurological dysfunction from brain/spinal cord/retinal vascular occlusion, stenosis, or injury - induced hemorrhage/infarction.

    Measured: During the days of follow-up(up to 12month ±60 days)

  7. Study device related serious adverse event rate during follow-up

    Measured: During the days of follow-up(up to 12month ±60 days)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Experimental Device A, a self-expanding rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China), Experimental Device B, a balloon-expandable rapamycin target-eluting stent (MicroPort NeuroTech, Shanghai, China) and Apollo® Intracranial Artery Stent System, a balloon-expandable bare-metal stent (MicroPort NeuroTech, Shanghai, China), in people with Intracranial Arteriosclerosis, run by MicroPort NeuroTech Co., Ltd. at 1 site 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 6 inclusion and 25 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: opening soon, as of the sponsor's last update on 13 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Huina Lu (+8615901703529, HuiNa.Lu@microport.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In-stent restenosis (ISR) rate at 12 months post-procedure (time frame: 12 months after surgery(±60days)). 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 Apr 2025.
