  "abstract": "Background Restenosis after stenting with a standard bare-metal stent (BMS) is the main cause of stroke recurrence for symptomatic intracranial atherosclerotic stenosis (sICAS). Whether a drug-coated balloon (DCB) could reduce the risk of restenosis for such patients is unknown. We aimed to investigate the efficacy and safety of DCB in reducing 6 month restenosis in patients with sICAS.Methods A prospective, multicenter, randomized, open-label, blinded endpoint clinical trial was conducted at 13 stroke centers across China. Eligible patients aged 18–80 years with sICAS defined as a recent transient ischemic attack (<180 days) or ischemic stroke (14–180 days) before enrollment attributed to a 70–99% atherosclerotic stenosis of a major intracranial artery were recruited between June 4, 2021 and September 15, 2022 (final follow-up: April 13, 2023). Patients were randomly assigned to receive a DCB (n=90) or BMS at a 1:1 ratio. The primary outcome was the post-procedure incidence of restenosis in the target lesion at 6 months (165–225 days). The safety outcome was post-procedure target vessel-related stroke (hemorrhage or ischemia) or death at 30 days.Results Among 201 randomized patients, 180 were confirmed eligible (mean age 58 years) and completed the trial. Compared with BMS, DCB was associated with a lower rate of post-procedure incidence of restenosis in the target lesion at 6 months (6.9% vs 32.9%, OR 0.15, 95% CI 0.05 to 0.42, P=0.0003). Regarding the safety outcome, post-procedure target vessel-related stroke (hemorrhage or ischemia) or death at 30 days did not differ between the two groups (4.4% vs 5.6%, OR 0.79, 95%CI 0.21 to 3.05, P=0.73).Conclusion DCB was superior to BMS in reducing the incidence of restenosis without increasing the risk of target vessel-related stroke or death within 6 months. Further trials comparing the outcomes of DCB with medical management for sICAS are warranted.Trial registration number ClinicalTrials.gov Identifier: NCT04631055.",
