E.4 | Principal exclusion criteria |
1. Previous known diabetes (type 1 or type 2 DM) or ongoing medication with any glucose-lowering agent.
2. A very high likelihood that the patient will die within the next 24 h on the basis of clinical and/or radiological criteria (e.g. malignant media infarct).
3. Patients expected to require endovascular or surgical intervention (e.g. i.a. thrombolysis or mechanical thrombectomy, carotid endarterectomy) during the treatment or follow-up period.
4. Previous participation in this trial or current participation in another investigational stroke treatment clinical trial
5. A high likelihood that the patient will not adhere to the study treatment and follow-up regimen
6. Plasma glucose <=7.0 mmol/L or >=10.0 mmol/L
7. Patients with lower level of consciousness (Glasgow Coma Scale <14, or NIHSS Item 1a=2 or RLS=2)
8. Malignancy, Pregnancy, Recent invasive procedures, Traumatic injury, Persistent hypertension, Severe liver disease, Alcohol abuse,
9. Refusal to consent.
10. Suspected pharyngeal palsy, e.g. inability to swallow.
11. Patients with dementia diagnosis
12. Patients with dysphasia (NIHSS>0 in item 9) or Verbal response <5 in Glasgow Coma Scale)*
13. Patients with known severe renal failure (creatinine clearance < 30 ml/min)
*Patient may be included in case of mild dysphasia (NIHSS=1 in item 9) provided that the NIHSS is performed by a physician and a witness not involved in the trial verify that the patient fully understand information provided to be included in the trial and then gives consent.

E.5 End points |
E.5.1 | Primary end point(s) |
• The primary safety outcome is a composite endpoint which is reached if any of the following events has occurred: Any serious or intolerable non-serious adverse events, death within 7 days, or symptomatic intracerebral haemorrhage (SICH) per SITS-MOST definition within 24 hours.
• Primary feasibility/efficacy outcome: At least 80% of the plasma glucose measurements are within the target intervals (5-7 mmol/L) over time (72 hours) in each patient and if 80% (24 of 30) of patients in the treatment group fulfil this criterion.
