Eligibility criteria

Inclusion Criteria:

* Diagnosis of LVO in the anterior circulation such that study drug administration can be initiated within 12 hours of LKW and at risk of MCE development, as defined as follows:
* Documented occlusion of terminus ICA and/or MCA on CTA or magnetic resonance angiogram and
* ASPECTS score \</=5 on NCCT and
* NIHSS \>15 for the non-dominant hemisphere and \>20 for the dominant hemisphere (or \> 20 if dominant/non-dominant hemisphere unknown)
* Present with a WUS \</=8 hours from awakening provided the above criteria are met
* Participants with a history of seizures on anti-epileptic medications may be included if they have been on stable doses of those medications for at least 12 weeks prior to LKW, they have not experienced seizures during that time frame, and their anti-epileptic medicines are continued during the study
