Edaravone Dexborneol in Large Ischemic Stroke: Real-World Experience from a Multicenter Study in China.

ABSTRACT:

Background

Edaravone dexborneol, a novel neuroprotective agent with combined antioxidant and anti-inflammatory properties, has demonstrated significant improvement in 90-day functional outcomes for patients with acute ischemic stroke. This study aimed to evaluate the outcomes of edaravone dexborneol in patients with acute ischemic stroke with large infarct core.

Methods

This prospective, multicenter, parallel-group, real-world cohort study was conducted between December 2022 and October 2023 across 72 centers in China. Participants were categorized into an exposed group (receiving edaravone dexborneol 37.5 mg/dose every 12 hours for 14 days) and an unexposed group (not receiving edaravone dexborneol). Propensity score matching (1:1) was used to balance baseline characteristics, and clinical outcomes were compared between the groups. The primary efficacy outcome was the proportion of patients achieving a modified Rankin Scale score of ≤2 at 90 days.

Results

After matching, the 90-day modified Rankin Scale ordinal shift was significantly better in the edaravone dexborneol group compared with the unexposed group (median: 2 [interquartile range, 1-4.5] versus 3 [interquartile range, 1-5]; unadjusted odds ratio [OR], 1.90 [95% CI, 1.04-3.46]; P=0.04). Patients in the edaravone dexborneol group had a higher rate of functional independence (58.8% versus 36.8%; unadjusted OR, 2.46 [95% CI, 1.23-4.90]; P=0.01) and a lower 90-day mortality rate (11.8% versus 19.1%; unadjusted OR, 0.56 [95% CI, 0.22-1.46]; P=0.24).

Conclusions

In patients with acute ischemic stroke with large infarct core, edaravone dexborneol improved the likelihood of achieving favorable functional outcomes at 90 days.
