Study summary

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.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 13, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
