EARLYS: Effect of Early Versus Late Initiation of Edaravone Dexborneol on Neural Function in Patients With Acute Ischemic Stroke
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- A 90-day mRS score of 0 to 2 in participants with acute ischaemic stroke [90 days]
To assess the proportion of participants (early and late) who started edaravone dextrol compared with placebo with a 90-day mRS score of 0 to 2 in participants with acute ischaemic stroke
Secondary Outcome Measures
- Neurological recovery [90 days]
The difference value of the NIHSS between Day 14/Day 90 and the baseline.
- Modified Rankin scale [90 days]
used to evaluate the functional outcomes after AIS，good prognosis (mRS score 0-2), generally good prognosis (mRS score 3-4) , Poor prognosis (mRS >4 points).
- Quality of life score (EQ-5D) [90 days]
Generic health status evaluated by EQ-5D questionnaire at the end of the therapy.
- The incidence of serious adverse events [90 days]
The percentage of the Severity Adverse Events within the 14 days/90 days of the therapy.
- All-cause mortality [90 days]
All-cause mortality at 90 days after randomization
