Brief summary
The primary objective of this study was to evaluate the efficacy and safety of initiation of edaravone dextivel therapy compared with placebo in patients with acute ischaemic stroke (early and late) and to explore the optimal time window for brain cell protective therapy of edaravone dexborneol.
Detailed description
This is a multicentre, randomized, double-blind, placebo-controlled trial that aims to investigate the efficacy and safety of (early and late) initiation treatment of Edaravone Dexborneol versus placebo in patients with acute ischemic stroke, and to explore the optimal time window for brain cell protective therapy of Edaravone Dexborneol. Patients who were eligible to the inclusion criteria and ineligible to the exclusion criteria will be stratified by time to trial drug: early (\<3 hours) and late (3-6 hours). Then each layer will be randomly assigned into two groups by a 1:1 ratio after the ICF was received. Patients in one arm will be given 15ml edaravone and dexborneol concentrated solution for injection (37.5mg, containing edaravone 30mg and dexborneol 7.5mg) twice a day for 10-14 days, and those in the other arm will be given an equivalent placebo drug. All patients will be followed up for 90 days. The primary outcome is the proportion of modified Rankin Scale 0-2 and the safety outcome is the proportion of severe adverse events.
Interventions
Edaravone and Dexborneol Concentrated Solution for Injection, 15 ml (37.5 mg, containing edaravone 30 mg and dexborneol 7.5 mg) in 3 ampoule bottles, twice a day for 10 to 14 days.
Edaravone and Dexborneol placebo, 15 ml in 3 ampoule bottles, twice a day for 10 to 14 days.

Intervention model description
Subjects with AIS who met the criteria for inclusion were stratified 1:1 from onset to use of the investigational drug: early (\< 3 hours) and late (3-6 hours). Each layer was then randomly assigned to two groups in a 1:1 ratio: the right group and the placebo group. Test group: Edaravone dextronicol concentrated solution for injection, 15ml / time (37.5mg / time, of which edaravone 30mg, (+)-2-camphol 7.5mg), that is, 3 bottles / time, 2 times a day, for 12±2 days; Control group: Equal dose of placebo, 15 ml / time, that is, 3 sticks / time, 2 times a day for 12±2 days.
