Status Recruiting

Clinical Trial Summary

This is a prospective, multi-center, open-access, single-arm trial to observe the real-world clinical efficacy of drug-eluting vertebral artery stenting system treatment for Atherosclerotic Vertebral Arteries Stenosis. Patients will be followed at 30 days, 6, and 12 months post-procedure and annually for 1 year within 3 years.

Clinical Trial Description

Stroke has been one of the most important causes of disability and death worldwide today. Ischemic stroke accounts for more than 50% of these strokes. The results of epidemiological surveys show that in 2018, more than 3 million new strokes occurred each year in China. In 2018, more than 3 million people suffered from a stroke, and more than 2 million people died from a stroke. Studies show that about 25% to 40% of transient ischemic attacks (TIA) or strokes occur in the posterior circulation. The subclavian and vertebral arteries are important blood vessels in the posterior circulation and are important original sites for ischemic strokes in the posterior circulation. About 20% of strokes in the posterior circulation are caused by extracranial vertebral artery stenosis (ECVAS). Endovascular intervention is the recommended treatment for ECVAS. It is effective in promoting the perfusion of brain tissue in the area of the responsible artery, thereby reducing the risk of stroke recurrence, improving neurological prognosis, and reducing symptoms. The drug-eluting stent is effective in reducing the incidence of postoperative restenosis (ISR), thus further reducing the long-term risk of stroke. Vertebral artery drug-eluting stents Maurora® was approved for marketing in 2020 and has been shown to be effective in reducing restenosis in clinical trials. The purpose of this study is to further investigate its long-term effectiveness in treating vertebral artery stenosis in the real world. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
