Glukagon-lignende Peptid-1 Receptorgonister til Endovaskulær Stroke Trombektomi (LEAST)
Et multicenter, prospektivt, randomiseret, åbent mærket, blindet slutpunkt, pilot klinisk forsøg, der evaluerer subkutan semaglutid hos patienter med akut iskæmisk apopleksi på grund af anterior cirkulation stor karokklusion behandlet med endovaskulær trombekomi
Endovascular thrombectomy (EVT) is a procedure that improves recovery for people who suffer from a stroke by removing blood clots from large blood vessels in the brain. However, even with this treatment, over half of the patients either pass away or are left with serious disabilities within three months. This is partly because, even in cases of a successful EVT, brain tissue damage continues to grow. Extent of brain damage is a major factor in how well a patient recovers. Studies in animals have shown that a drug called semaglutide might help protect the brain and improve recovery after a stroke. Semaglutide is currently used for the treatment of diabetes and obesity and is given as a weekly injection under the skin.
The investigators are hoping to test whether giving semaglutide to stroke patients undergoing EVT can improve their recovery. A very large study at many hospitals is needed to answer this question. The investigators are starting with a smaller study to gain information on whether it is possible to perform a larger definitive one, and if so, how best to plan for it. In this first step we will study 100 patients with stroke who are scheduled for EVT in approximately 10 stroke centers across Canada. These patients will be randomly divided (like flipping a coin) into two groups: one will receive weekly semaglutide injections for 12 weeks, while the other will not receive the drug. The investigators will track how many patients agree to participate, how many stay in the study, and how well they follow the treatment plan. The investigators will also monitor the patients' recovery, overall health, and any side effects from the treatment. These results will provide important information to plan our larger study with the goal of reducing death rates and long-term disability in stroke patients undergoing EVT.

Background/Importance:
Endovascular thrombectomy (EVT) has substantially improved functional outcomes and decreased mortality in acute ischemic stroke patients with large vessel occlusions (LVOs). However, more than half of the patients die or have significant disability at 90 days after EVT. Studies suggest considerable infarct growth despite successful EVT and infarct volume predicts survival and functional outcome after EVT. There is an unmet need for interventions to reduce infarct growth and improve the functional outcomes of patients with an acute LVO who undergo EVT. Glucagon-Like Peptide-1 receptor agonists (GLP-1 RAs) have been suggested to decrease infarct growth and improve motor and sensory impairments in both diabetic and non-diabetic animal models of stroke. GLP-1 RAs also consistently decreased the risk of major adverse cardiovascular events (MACE), with the most profound effect in stroke prevention, in large-scale randomized clinical trials (RCTs) of patients with and without history of diabetes.
Research Aims:
The overall goal of this study is to test whether semaglutide can improve the functional outcomes of adults with acute ischemic stroke attributed to an intracranial LVO who are planned for treatment with EVT. We are performing a pilot trial to obtain the factual feasibility prerequisites essential for the planning, design, funding and execution of a subsequent main phase trial.
Methods:
Glucagon-like peptide-1 receptor agonists for Endovascular Stroke Thrombectomy (LEAST) is a multicentre, prospective, randomized, open label, blinded endpoint (PROBE) pilot clinical trial. LEAST will recruit a total of 100 adult patients scheduled to receive EVT at approximately 10 high-volume stroke research centres in Canada over 1.5 to 2 years. Participants fulfilling the inclusion and exclusion criteria will be randomly assigned up to 6 hours from the end of the EVT procedure, defined as the time of the last angiographic run, to either receive semaglutide (0.25 mg subcutaneous [SC] weekly for 4 weeks followed by 0.5 mg SC weekly for another 8 weeks) or to no semaglutide treatment.
Outcomes:
The primary feasibility endpoint is recruitment rate.
Secondary feasibility endpoints include retention rates and medication adherence.
Exploratory outcomes include:
Proportion of participants with functional independence (mRS scores 2 or less) at 90±14 days; Absolute difference in the NIHSS scores between randomization and 36±12 hours; Functional outcome at day 7±2, assessed with the ordinal mRS scores; Proportion of participants with functional independence (mRS scores 2 or less) at day 7±2; Functional outcome at day 30±7, assessed with the ordinal mRS scores; Proportion of participants with functional independence (mRS scores 2 or less) at day 30±7; Functional outcome at 90±14 days, assessed with the ordinal mRS scores; Quality of life at 90±14 days, assessed with the EQ-5D-5L scale; Recurrent stroke (ischemic, hemorrhagic or uncertain) by 90±14 days; Occurrence of MACE (any stroke, myocardial infarction cardiovascular death) by 90±14 days.
