Methylprednisolone With Endovascular Thrombectomy for Large Ischemic Stroke (MATCH): A Randomized Controlled Trial

Обзор

It is uncertain whether intravenous methylprednisolone improves outcomes for acute anterior circulation large vascular occlusion (LVO) patients with a large infarct core. In this study, the investigators assume that methylprednisolone plus endovascular thrombectomy (EVT) might be superior to EVT alone for patients who have evidence of a large infarct volume. The objective of the study was to establish the efficacy and safety of methylprednisolone with EVT in patients presenting with symptoms of acute ischemic stroke from LVO in the anterior circulation and having a large infarct volume.

Подробное описание

MATCH is a multicentered, prospective, randomized, controlled trial. A total of 1614 patients (age ≥18 years) with NIHSS ≥6 and pre-stroke modified Rankin Scale (mRS) 0-2, within 24 hours of symptom onset of acute ischemic stroke, who has the imaging evidence of an occlusion of the intracranial internal carotid artery (ICA) and/or M1/M2 segment of middle cerebral artery (MCA), large infarct core \[defined as: 1) NCCT (non-contrast computed tomography) ASPECTS (Alberta Stroke Program Early CT Score) 0-5, decided on last head CT scan before randomization. Or 2) Ischemic core volume ≥70ml, determined either on a diffusion-weighted MRI map based on an ADC (Apparent Diffusion Coefficient) threshold of less than 620 or on CTP (computed tomography perfusion) image with rCBF\<30%\] will be enrolled. Patients fulfilling all of the inclusion criteria and none of the exclusion criteria will be randomized 1:1 into two groups after offering informed content. One group will receive methylprednisolone plus EVT, the other group will receive methylprednisolone simulant plus EVT. The primary objective is to evaluate the efficacy of methylprednisolone with EVT in patients presenting with symptoms of acute ischemic stroke from LVO in the anterior circulation and having a large infarct volume. The study consists of four visits including the day of randomization, 36 hours after randomization, 7 days or discharge, and 90 days. The primary outcome is a shift in the distribution of scores on the mRS at 90 days. All the related investigative organization and individuals will obey the Declaration of Helsinki and Chinese Good Clinical Practice standard. A Data and Safety Monitoring Board (DSMB) will regularly monitor safety during the study. The trial has been approved by Institutional Review Board (IRB) and Ethics Committee (EC) in Sun Yat-Sen Memorial Hospital.
