Multicentre Randomized Trial of Ghrelin in Anterior Circulation Ischemic Stroke Treated With Endovascular Thrombectomy. A Randomized Phase 2 Trial

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.

Inclusion Criteria:a clinical diagnosis of acute ischemic stroke, caused by intracranial large vessel occlusion of the anterior circulation (distal intracranial carotid artery or middle (M1/proximal M2) cerebral artery) confirmed by neuro-imaging (CTA or MRA),treatment with EVT, defined as groin puncture in the angio suite,CT or MRI ruling out intracranial hemorrhage,a pre-EVT score of at least 10 on the NIHSS,age of 18 years or older,written informed consent (deferred).Exclusion Criteria:pre-stroke disability defined as mRS ≥ 2,life expectancy shorter than one year,child-bearing potential.
