Detaljeret beskrivelse

The study population are patients with acute anterior circulation large vessel occlusion stroke and planned to undergo endovascular treatment. All participants are randomly assigned in a 1:1 ratio to the tocilizumab group or the placebo group. In tocilizumab group, participants will receive tocilizumab combined endovascular treatment. And in placebo group, participants will receive placebo combined endovascular treatment. All participants will be visited immediately postoperatively, at 24 hours, 7 days, and 90 days after randomization.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Tocilizumab group

Endovascular treatment combined 240 mg tocilizumab injection once.

240 mg of tocilizumab injection will be diluted in 0.9% NaCl solution to prepare a total solution volume of 100 mL. The solution will be administered via intravenous infusion immediately after randomization, and no later than 30 minutes, with an infusion duration of more than 1 hour.

Placebo komparator: Placebo group

Endovascular treatment combined equivalent volume of placebo once.

An equivalent volume of placebo will be diluted in 0.9% NaCl solution to prepare a total solution volume of 100 mL. The solution will be administered via intravenous infusion immediately after randomization, and no later than 30 minutes, with an infusion duration of more than 1 hour.
