Brief 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.

Interventions

Design outcomes

Primary

MeasureTime frameDescription
The ordinal shift of modified Rankin Scale90±14 days after procedureThe 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

Secondary

MeasureTime frameDescription
Proportion of patients with functional independence outcome (mRS 0-1) at day 9090±14 days after procedureModified Rankin scale (range, 0 to 6, 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)
Proportion of patients with functional independence outcome (mRS 0-2) at day 9090±14 days after proceduremodified Rankin scale (range, 0 to 6, 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)
Proportion of patients with ambulatory and self-care capable outcome (mRS 0-3) at day 9090±14 days after procedureModified Rankin scale (range, 0 to 6, 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)
Health-related Quality of Life of Participants Assessed by EuroQol-5 Dimension-5 Level90±14 days after endovascular treatmentParticipants rated themselves on five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension was distributed from no problems at all to very serious problems.
Activities of Daily Living of Participants Assessed by Bathel Index90±14 days after procedure10 rating items, each of which is categorized into 2-3 out of 5 levels: Unable, Needs major help, Needs help, Needs minor help, and Independent, and each item has a different score for each level. Independence was positively correlated with the final score.
Neurological Function of Participants Assessed by National Institute of Health Stroke ScaleDay 1, Day 3, Day 5-7 after EVT (or at discharge, when the patient is discharged on day 5-7)Zero indicates no stroke symptoms, 1-4 , 5-15, 16-20, 21-42 indicate minor, moderate, moderate to severe, and severe stroke, respectively.

Other

MeasureTime frameDescription
Intracranial Hemorrhage (ICH)48-72 hours after EVTICH means Heidelberg classification 2 or above intracerebral hemorrhage with increment of NIHSS ≥ 4.
