NCT06437600

Brief Summary

A multicenter, prospective, open-label, blinded endpoint, randomized controlled trial that aims to evaluate the effect of immediate angioplasty (with or without stenting) for acute ischemic stroke (AIS) with severe intracranial atherosclerotic stenosis (ICAS) in improving the 90-day functional outcome.

Outcome Measures

Primary Outcomes (1)

  • The modified Rankin Scale (mRS) 0-2

    The proportion of the mRS 0-2 at 90 days.

    90(±7) days

Secondary Outcomes (7)

  • The mRS 0-1

    90(±7) days

  • The mRS 0-3

    90(±7) days

  • The shift analysis of the mRS distribution

    90(±7) days

  • The change of National Institute of Health Stroke Scale (NIHSS)

    7(±1) days or discharge, whichever came first

  • Any new stroke (ischemic/hemorrhagic) or all-cause mortality

    within 30 days

  • +2 more secondary outcomes

Other Outcomes (3)

  • SAFETY OUTCOME: Symptomatic intracranial hemorrhage

    24 (±12) hours

  • SAFETY OUTCOME: Mortality

    90(±7) days

  • SAFETY OUTCOME: Any intracranial hemorrhage

    24 (±12) hours

Study Arms (2)

The intervention group

EXPERIMENTAL

Participants will receive immediate angioplasty (with or without stenting) for the culprit vessel and the target residual stenosis should be less than 50%. All participants will receive the best medical treatment (BMT).

Procedure: Immediate angioplasty

The control group

NO INTERVENTION

Participants will receive BMT alone.

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 years or older.
  • Diagnosed with AIS and baseline NIHSS ≥6.
  • Pre-stroke mRS ≤2.
  • Time from symptom onset to randomization ≤ 24 hours; the onset time refers to "Last Known Well" (LKW).
  • Non-contrast CT ASPECTS score ≥6.
  • CTA confirmed severe ICAS (70-99%) of the intracranial segment of the internal carotid artery, or M1 or M2 segment of the middle cerebral artery, and is presumed to be responsible for the stroke.
  • Informed consent signed by the patient or authorized representative.

You may not qualify if:

  • Normal diameter of the culprit vessel \<2.0 mm.
  • Isolated perforator artery infarction (except for combined cortical hypoperfusion).
  • Hemorrhagic stroke within the past 90 days.
  • Cerebrovascular conditions such as vasculitis, moya-moya disease, arterial inflammatory stenosis, vasospasm, traumatic dissection, etc..
  • Severe calcification at the stenosis site, where expected residual stenosis ≤50% cannot be achieved with procedure.
  • Known cardiac thrombus source (e.g., atrial fibrillation, patent foramen ovale, infective endocarditis).
  • INR \>1.7 when using warfarin; coagulation dysfunction or uncorrectable bleeding factors.
  • Platelet count \<50×10\^9/L.
  • Intracranial hemorrhage confirmed by CT or MRI.
  • Women who are pregnant or breastfeeding.
  • Participation in other intervention clinical trials.
  • Known severe renal insufficiency with glomerular filtration rate \<30 ml/min or blood creatinine \>220 μmol/L (2.5 mg/dl).
  • Severe allergy to contrast (non-mild rash allergy) or absolute contraindication to iodine contrast.
  • Aortic dissection.
  • Concomitant intracranial tumor (except for meningioma \<10mm) or arteriovenous malformation.
  • +5 more criteria
