About half of the patients with acute ischemic stroke treated with endovascular thrombectomy (EVT) remain dependent on the help of others or die in the first 90 days. We hypothesize that treatment with ghrelin, started in the first six hours after stroke onset, improves early recovery and long-term functional outcome in these patients. Ghrelin is a naturally occurring hormone and mildly excitatory neurotransmitter also known as the 'hunger hormone.' Treatment with acylated ghrelin consistently improved functional and histological recovery in in vitro and in vivo models of ischemic stroke.
We will include 80 patients with acute ischemic stroke caused by large vessel occlusion of the anterior circulation, eligible for EVT. The study population will be drawn from adult patients with acute ischemic stroke treated with EVT at UMC Utrecht, Rijnstate, MST or Isala.
Treatment in the intervention group will consist of intravenous acylated ghrelin, 600micrg dissolved in 50cc normal saline, by bolus (short term) infusion in 30 minutes, twice daily, for five days. This treatment will be additional to standard treatment, including intravenous thrombolysis, if indicated.

| Measure | Description | Time Frame |
|---|---|---|
| National Institutes of Health Stroke Scale score | The primary outcome measure is the score on the National Institutes of Health Stroke Scale at seven days (±1) after stroke onset or at discharge, if earlier. The NIHSS is a continuous scale to evaluate the severity of stroke by assessing a patient's performance. Scores range from 0 to 42, with higher scores indicating a more severe deficit. | 7 days after stroke onset |
| Measure | Description | Time Frame |
|---|---|---|
| Modified Rankin Scale score | The score on the Modified Rankin Scale at 90 days after stroke onset. The mRS is an ordinal hierarchical scale that describes disabilities encountered post stroke, incorporating six categories from 0 (complete recovery) up to and including 5 (severe disability). 'Death' is assigned a score of 6 . | 90 days after stroke onset |

This will be a phase 2 multicenter clinical trial with random treatment allocation, open label treatment and blinded endpoint assessment (PROBE design). The intervention contrast will be intravenous acylated ghrelin in addition to standard care (intervention group) vs. standard care alone (control group).
