MR GENTLE-multicentre randomised controlled trial of ghrelin in anterior circulation ischaemic stroke treated with endovascular thrombectomy: a phase 2 trial.
Trial report in Trials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05726240 (Multicentre Randomized Trial of Ghrelin in Anterior Circulation Ischemic Stroke Treated With Endovascular Thrombectomy. A Randomized Phase 2 Trial), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
BACKGROUND AND
aimsAbout half of the patients with acute ischaemic stroke treated with endovascular thrombectomy (EVT) remains dependent or dies in the first 90 days. Ghrelin is a naturally occurring hormone and mildly excitatory neurotransmitter that improved functional, histological, and cytological recovery in in vitro and in vivo ischaemia-reperfusion models. Acylated ghrelin (i.e. the bioactive form) has shown safety in a range of populations, including patients with cardiovascular or neurodegenerative disease. We hypothesise that treatment with acylated ghrelin improves early recovery and long-term functional outcome in patients with ischaemic stroke treated with EVT.
methodsWe propose an investigator-initiated, phase 2, randomised, clinical trial with open-label treatment and blinded endpoint assessment in 80 patients with anterior circulation ischaemic stroke treated with EVT and a pre-EVT National Institutes of Health Stroke Scale (NIHSS) score ≥ 10. Patients will be randomised to intravenous acylated ghrelin, 600 µg twice daily for 5 days and started within 6 h of symptom onset, in addition to standard care vs. standard care alone. The primary outcome is the NIHSS score on day 7 adjusted for pre-EVT NIHSS and other relevant baseline characteristics. Secondary outcomes include infarct size on MRI at day 3, adverse events, and functional recovery at 90 days. The primary analysis will be a single comparison between the treatment groups of the primary outcome according to the intention-to-treat principle. The primary effect variable will be the adjusted beta for the difference in NIHSS score, estimated with multi-variable linear regression analysis. DISCUSSION: If administration of acylated ghrelin is found safe and potentially effective in patients with ischaemic stroke treated with EVT, this study can inform the sample size calculation for a subsequent randomised phase 3 trial to assess efficacy.
trial registrationThe trial has been approved and registered on ClinicalTrials.gov (NCT05726240). The first patient has been included in November 2024.
