Semaglutide 0.5 mg: 0.5mg semaglutide injection before and 1 week after endovascular treatment.
Standard medical treatment: Standard medical management
Study summary
The goal of this clinical trial is to learn if semaglutide works to treat acute ischemic stroke (AIS). It will also learn about the safety of semaglutide in AIS. The main question it aims to answer is: Does semaglutide improve the 90-days functional outcome in participants with acute large vessel occlusion who receive the endovascular treatment (EVT)? Researchers will compare semaglutide injection to non-injection to see if semaglutide works to improve the functional outcome in participants with EVT.
Participants will:
* Receive 0.5mg semaglutide injection before (Day 0) and 1 week (Day 7) after EVT , or EVT alone.
* Have additional blood test before and after EVT.
* Receive neurological assessment before EVT, Day 1, Day 3, Day 5-7 after EVT or on hospital discharge (whichever earlier), Day 90±14 after EVT. Audio or video of the assessment may be recorded if possible.
* Receive brain CT + CT angiogram + CT perfusion and MRI after EVT, where the CT scan may be repetitive.

Primary outcome measure(s)
The ordinal shift of modified Rankin Scale — 90±14 days after procedure The Modified Rankin Scale (mRS) measures degree of disability/dependence after a stroke, with a score of 0 indicating no disability, 1 no clinically significant disability, 2 slight disability, 3 moderate disability but remaining able to walk unassisted, 4 moderately severe disability, 5 severe disability, and 6 death
