Pre-stroke Eastern Cooperative Oncology Group (ECOG) performance status ≥3; 10. Hypersensitivity to edaravone, (+)-borneol, or any excipients; 11. Pregnancy, lactation, or planned pregnancy; 12. Participation in another clinical trial within 30 days prior to randomization or current enrollment in other interventional studies; 13.Any other condition deemed inappropriate for participation by the investigator.

Patients with acute ischemic stroke (AIS) who also have active malignancies face a more complex clinical scenario, with limited treatment options and generally poor prognoses. The coexistence of these two conditions can interact through inflammatory and oxidative stress pathways, forming a vicious cycle that exacerbates the patient's condition. Edaravone dexborneol injection exhibits significant antioxidant and anti-inflammatory effects, effectively scavenging free radicals in the body, thereby potentially improving the outcomes of AIS patients. Our team's preliminary retrospective study demonstrated that edaravone dexborneol injection can promote neurological recovery in AIS patients with active malignancies and shows a favorable safety profile. Therefore, this study aims to conduct a multicenter randomized controlled trial to evaluate the efficacy and safety of edaravone dexborneol injection in treating AIS patients with active malignancies, with the goal of providing evidence-based medical support and more effective therapeutic strategies for this specific patient population.

Arms

Experimental: Intervention group

Subjects randomized to the trial group will receive edaravone dexborneol injection at a dose of 37.5 mg (consisting of 30 mg edaravone and 7.5 mg dexborneol) administered twice daily with a fixed 12-hour interval between doses. The study drug will be diluted in 100 mL of normal saline and delivered via intravenous infusion over 30 minutes. This treatment regimen will be maintained for a duration of 10 to 14 days, in addition to standard stroke care. Strict adherence to the dosing schedule and infusion protocol will be ensured to maintain treatment consistency across study sites.

Active Comparator: Control group

Subjects randomized to the control group will receive conventional standard therapy for acute ischemic stroke without the addition of edaravone dexborneol. The standard treatment regimen, which may include antiplatelet therapy, anticoagulation (if indicated), blood pressure management, and other evidence-based interventions, will be administered continuously for 10 to 14 days according to current clinical guidelines. All patients in this group will receive the same intensity of monitoring and follow-up as the experimental group to ensure comparable assessment of outcomes.

Interventions

Drug: - edaravone dexborneol injection

The experimental intervention involved twice-daily administration of edaravone dexborneol injection at a dose of 37.5 mg (containing 30 mg edaravone and 7.5 mg dexborneol), with doses spaced exactly 12 hours apart. For each infusion, the study medication was first diluted in 100 mL of normal saline (0.9% sodium chloride solution) and then administered as a controlled intravenous infusion over a precisely timed 30-minute period. This standardized dosing regimen was maintained consistently throughout the 10-14 day treatment course for all participants in the experimental group.

Drug: - Standard therapeutic protocol

The standard treatment regimen, which may include antiplatelet therapy, anticoagulation (if indicated), blood pressure management, and other evidence-based interventions, will be administered continuously for 10 to 14 days according to current clinical guidelines.
