Clinical Trial Summary

The purpose of the RCT trial is to determine whether DCB is not inferior to stent in treating intracranial de novo stenosis.

Description:

This trial is a prospective, multi-center, 1:1 randomized using paclitaxel coated balloon versus stent to treat intracranial stenosis of 70-99% degree. And primary endpoint is angiographic restenosis at 6 months post-procedure.

Eligibility

Inclusion Criteria:

• 18 to 80 years of age;

• Patients with symptomatic intracranial atherosclerotic stenosis;

• Patients with intracranial arterial de novo stenosis confirmed by digital subtraction angiography (DSA);

• Confirmed by DSA,the diameter of the target vessel is between 2.5mm-4.5mm ; according to WASID method, the degree of stenosis of the target lesion is 70%-99%;

• Baseline mRS score =2;

• Voluntarily participate in this study and sign the informed consent form.

Exclusion Criteria:

• Patients with stroke within 2 weeks before procedure;

• Patients with stroke caused by perforating artery occlusion;

• Any history of brain parenchymal or other intracranial subarachnoid, subdural or extradural hemorrhage in the past 30 days;

• Those who have received thrombolysis within 24 hours before procedure;

• Deterioration of neurological function within 24 hours before procedure (defined as NIHSS score increased by = 4 points over the baseline);

• The vascular path showed in angiography is so tortuous that it is difficult to advance catheters to the target lesion or retrieve;

• Lesions that investigators believe are not suitable for stenting;

• Patients with thrombus in target vessel;

• In addition to the target lesion, there are still other de novo lesion or ISR lesion with more than 70% diameter stenosis in intracranial arteries that need to be treated at the same time;

• After endovascular treatment of the target lesion, there is still a stenosis of more than 50% in the main blood supplying artery or an obstructive lesion in the distal vessel of target lesion;

• Major surgery (including open femoral artery, aortic or carotid artery surgery) within the past 30 days or planned within 90 days;

• Patients with renal artery, iliac artery, and coronary artery requiring simultaneous intervention;

• Combined with intracranial tumor, aneurysm or intracranial arteriovenous malformation;

• Intracranial artery stenosis caused by non-atherosclerotic lesions, including:

arterial dissection, moya-moya disease, vasculitis disease, herpes zoster, varicella-zoster or other viral vascular diseases, neurosyphilis, any Other intracranial infections, any intracranial stenosis related to cerebrospinal fluid cells, radiation-induced vascular disease, fibromuscular dysplasia, sickle cell disease, neurofibromatosis, central nervous system benign vascular disease, postpartum vascular disease, suspected Vasospasm, suspicious embolism recanalization, etc.;

• Cardiac stroke or potential cardiogenic thromboembolism, with any of the following cardiogenic embolism causes: chronic or paroxysmal atrial fibrillation, mitral valve stenosis, mechanical valves, endocarditis, intracardiac thrombus or implant, dilated cardiomyopathy, spontaneous acoustic imaging of the left atrium;

• Patients with myocardial infarction within 6 weeks before procedure;

• Those who cannot tolerate general anesthesia due to insufficiency of important organs such as heart and lungs;

• Patients with known severe hepatic and renal dysfunction;

• Patients with hemoglobin<100g/L, platelet count<100×1,000,000,000/L, INR>1.5 or there are uncorrectable factors leading to bleeding(if there are multiple checks, the last one shall prevail);

• Patients who cannot receive dual antiplatelet therapy due to existing diseases or are tolerant to dual antiplatelet therapy confirmed by relevant test;

• Patients with known severe allergies or contraindications to heparin, paclitaxel, contrast agents and other related intravascular treatment drugs;

• Current alcohol or drug abuse, uncontrolled severe hypertension (systolic blood pressure>180mmHg or diastolic blood pressure>110mmHg);

• Life expectancy <1 year;

• Pregnant or lactating women;

• Patients who cannot complete the follow-up due to cognitive, emotional or mental illness;

• Patients who are participating in other drug/device clinical trials and have not completed all follow-ups required by the programmer;

• According to the judgement of the investigator, other situations that are not suitable for enrollment.
