Drug-Coated Balloon vs Aggressive Medical Management for High-Risk Symptomatic Intracranial Atherosclerotic Stenosis (DRBEYOND2)

20 de setembro de 2026 atualizado por: Dapeng Mo, Beijing Tiantan Hospital

Drug-coated Balloon for Endovascular Treatment Versus Aggressive Medical Management in High-Risk Symptomatic Intracranial Atherosclerotic Stenosis

DR.BEYOND-2 is an investigator-initiated, prospective, multicenter, randomized, open-label, blinded-endpoint, parallel-group clinical trial designed to evaluate the efficacy and safety of drug-coated balloon (DCB) angioplasty plus aggressive medical management compared with aggressive medical management alone in patients with high-risk symptomatic intracranial atherosclerotic stenosis (sICAS).

A total of 570 eligible patients will be randomized in a 1:1 ratio to the DCB group or the medical management group. Patients assigned to the DCB group will undergo DCB angioplasty in addition to aggressive medical management, with rescue stenting permitted when clinically necessary according to the study protocol. Patients assigned to the control group will receive aggressive medical management alone.

The primary endpoint is the composite of any stroke or death within 30 days after enrollment and ischemic stroke in the territory of the qualifying artery from day 31 through 1 year. Participants will be followed for up to 3 years to further evaluate recurrent ischemic events, vascular outcomes, functional outcomes, and long-term safety.

Descrição detalhada

Symptomatic intracranial atherosclerotic stenosis (sICAS) is an important cause of ischemic stroke and recurrent cerebrovascular events. Although aggressive medical management is the standard treatment, patients with severe stenosis and high-risk clinical or hemodynamic features may remain at substantial risk of recurrent ischemic events. Previous randomized trials of intracranial stenting have raised concerns regarding periprocedural safety, whereas balloon angioplasty has shown potential benefit but may be limited by arterial dissection, elastic recoil, and restenosis. Drug-coated balloon angioplasty may provide an alternative endovascular strategy by combining luminal enlargement with local delivery of an antiproliferative agent while minimizing permanent intracranial implants.

DR.BEYOND-2 is an investigator-initiated, prospective, multicenter, randomized, open-label trial with blinded endpoint assessment. The study will enroll 570 patients with high-risk symptomatic intracranial atherosclerotic stenosis involving a major intracranial artery. Eligible patients must have had a recent ischemic stroke or transient ischemic attack attributable to the qualifying artery, severe intracranial stenosis, and prior treatment with at least one antithrombotic agent and/or guideline-based vascular risk-factor management. For anterior-circulation lesions, evidence of hemodynamic compromise is additionally required according to the protocol.

Participants will be randomly assigned in a 1:1 ratio to DCB angioplasty plus aggressive medical management or aggressive medical management alone. In the intervention group, DCB angioplasty will be performed using a submaximal angioplasty strategy. Rescue stenting may be used in cases of severe dissection, significant residual stenosis, or marked elastic recoil according to predefined procedural criteria.

Both treatment groups will receive standardized aggressive medical management, including antiplatelet therapy, lipid-lowering therapy, blood-pressure control, diabetes management, and management of other vascular risk factors. The medical regimen and risk-factor targets will be applied consistently across both treatment groups.

The primary endpoint is the composite of any stroke or death within 30 days after enrollment and ischemic stroke in the territory of the qualifying artery from day 31 through 1 year. Secondary outcomes include recurrent ischemic stroke or transient ischemic attack, target-vessel revascularization, hemorrhagic events, mortality, functional outcome, quality of life, and target-vessel restenosis. Exploratory outcomes include high-resolution magnetic resonance imaging changes of the target vessel and clinical and vascular outcomes through 3 years.

Participants will undergo scheduled follow-up at 7 days, 30 days, 3 months, 6 months, and 12 months, followed by assessments every 6 months through 3 years. The trial is designed to determine whether DCB-based endovascular treatment in addition to aggressive medical management can reduce recurrent cerebrovascular events while maintaining acceptable procedural safety in patients with high-risk sICAS.

Experimental: Drug-Coated Balloon Angioplasty Plus Aggressive Medical Management

Participants assigned to this group will undergo drug-coated balloon angioplasty in addition to aggressive medical management. Rescue stenting is permitted when clinically necessary according to predefined procedural criteria, including severe dissection, significant residual stenosis, or marked elastic recoil.

Participants randomized to the experimental group will undergo intracranial drug-coated balloon angioplasty using a submaximal angioplasty strategy. Predilation with an uncoated balloon is performed before drug-coated balloon angioplasty. Rescue stenting is permitted when severe dissection, residual stenosis >50%, marked elastic recoil, or other protocol-defined conditions occur.

Comparador Ativo: Aggressive Medical Management Alone

Participants assigned to this group will receive aggressive medical management alone, including standardized antiplatelet therapy and intensive management of vascular risk factors.

Aggressive medical management will be provided to participants in both groups and includes antiplatelet therapy, intensive lipid-lowering treatment, blood pressure and glucose control, and management of other vascular risk factors. Aspirin 100 mg/day is administered throughout follow-up, with clopidogrel 75 mg/day during the first 90 days after enrollment. Alternative antiplatelet therapy may be used according to platelet function or CYP2C19 genotype when appropriate.
