AB Background Although endovascular stenting is considered an effective and safe therapeutic option for symptomatic intracranial atherosclerotic disease (sICAD), an elevated rate of restenosis remains an important issue for the conventional bare-metal stent (BMS). Recent evidence from observational studies suggests that applying drug-coated balloons (DCB) in sICAD may decrease restenosis occurrence. Additional large randomised studies are warranted to provide firmer evidence and to determine which patients would benefit most from DCB.Aim To design a randomised trial to examine DCB angioplasty (Taijieweiye intracranial paclitaxel-coated balloon catheter) versus BMS stenting (Wingspan intracranial stent system) in patients with sICAD.Design This is a multicentre, prospective, randomised, open-label, blinded end-point study to assess whether DCB angioplasty reduces the risk of restenosis compared with BMS stenting in sICAD patients with high-grade stenosis (≥70%–99%). Our goal is to randomly assign 198 eligible individuals at a 1:1 ratio to undergo DCB angioplasty (intervention group) or BMS stenting (control group).Outcome The primary efficacy outcome is restenosis at 6 months post treatment, that is, >50% stenosis in or within 5 mm of the treated segment and >20% absolute luminal loss. The primary safety outcome is stroke or death within 30 days post treatment.Discussion The DRug-coated Balloon for Endovascular treatment of sYmptOmatic intracraNial stenotic Disease trial aims to produce strong evidence on the efficacy and safety of DCB angioplasty as a promising therapeutic option for sICAD cases with high-grade stenosis.Data are available on reasonable request.
