Abstract P148: Safety And Efficacy Of Edaravone Dexborneol Versus Edaravone Alone For The Treatment Of Acute Ischemic Stroke Patients With Hypertention: Analysis From Taste Trial

Background and Aims: Evidenced by TASTE phase III trial, 90-day good functional outcomes favored the edaravone dexborneol group versus edaravone group when administered within 48 hours after Acute Ischemic Stroke (AIS). The present study aimed to investigate the effects of edaravone dexborneol versus edaravone in AIS patients with hypertension medical history. Methods: This study was a subgroup analysis of the TASTE trial with hypertension medical history. The primary outcome was the proportion of patients with modified Rankin Scale (mRS) score ≤1 on day 90 after randomization. The secondary outcome was the mRS score on day 90. The safety endpoints were the incidences of adverse events, serious adverse events and deaths. Analyses were by intention to treat. Results: We included 767 AIS patients with hypertension (390 in edaravone dexborneol group, 377 in edaravone group) in this analysis. Among them, 252 (64.62%) in edaravone dexborneol group versus 199 (52.79%) in edaravone group reached mRS score ≤1 on D90, revealing significantly higher proportion of mRS score ≤1 on D90 in edaravone dexborneol group (OR 1.63 [95% CI, 1.22-2.18]; P<0.001). Significant differences occurred between two groups in mRS score on D90 ([OR 1.32 [95% CI, 1.02-1.72]; P=0.038). The safety outcomes indicated that the two groups were similar in incidences of adverse events (366 [93.85%] versus 352 [93.37%], p=0.787), serious adverse events (48 [12.31%] versus 34 [9.02%], p=0.1405) and number of deaths (6 [1.54%] versus 4 [1.06%], p=0.56). Conclusion: This analysis demonstrated that AIS patients with hypertension receiving edaravone dexborneol had better functional outcomes than those with edaravone, which provided evidences for the clinical application of edaravone dexborneol in AIS patients with hypertension.
