Methylprednisolone Adjunctive to Endovascular Treatment for Stroke

Phase 3
Not yet recruiting
Conditions
Acute Ischemic Stroke
Interventions
Drug: Placebo (Methylprednisolone sodium succinate simulant)
Registration Number
NCT06360458
Lead Sponsor
Wan-Jin Chen
Brief Summary

The efficacy and safety of methylprednisolone in acute ischemic stroke patients with large infarct cores (ASPECTS score \< 6) due to anterior circulation large vessel occlusion have not been clearly established. This is a multi-center, randomized, double-blind, placebo-controlled trial to investigate early combination therapy with methylprednisolone for reperfusion in acute large core infarction.

Inclusion Criteria
  • Age ≥ 18 years.
  • Presenting with AIS with symptoms within 12 hours from time last known well.
  • Anterior circulation ischemic stroke was determined according to clinical symptoms and imaging examination.
  • Occlusion of the intracranial internal carotid artery, the M1- or M2-segment of the middle cerebral artery confirmed by CT angiography, MR angiography, or digital subtraction angiography.
  • Baseline National Institutes of Health Stroke Scale (NIHSS)≥6.
  • Baseline Alberta Stroke Program Early CT Score (ASPECTS)<6.
  • Planned treatment with endovascular therapy (EVT).
  • Informed consent obtained from patients or their legal representatives.
Exclusion Criteria
  • Intracranial hemorrhage confirmed by cranial computed tomography (CT) or magnetic resonance imaging (MRI).
  • mRS score >= 2 before onset.
  • Pregnant or lactating women.
  • Allergic to contrast agents or glucocorticoids.
  • Participating in other clinical trials.
  • Systolic blood pressure >185 mmHg or diastolic pressure >110 mmHg, and oral antihypertensive drugs can not control.
  • Genetic or acquired bleeding constitution, lack of anticoagulant factors, or oral anticoagulants and INR > 1.7.
  • Blood sugar < 2.8 mmol/L (50 mg/dl) or > 22.2 mmol/L (400 mg/dl), platelet < 90 x 10^9/L.

  • Life expectancy due to any advanced disease < 6 months.
  • Follow-up is not expected to be completed.
  • Intracranial aneurysm and arteriovenous malformation.
  • Brain tumors with imaging mass effect.
  • Macular edema.
  • Möbitz type II second-degree/third-degree atrioventricular block or sick sinus syndrome or medical history.
  • Systemic infectious disease.
