- A disabling motor deficit at the moment of inclusion, defined as having a total Middle Cerebral Artery (MCA) score between 15 and 65
- Treated before 7 h (6 h and 59 minutes) after the estimated stroke onset
- If the subject had a stroke during the night, the onset of stroke is assumed to be the last time the subject was seen awake and normal, or last time the subject remembered he/she was awake and normal

- A medical or neurological disease interfering with the assessments and causing a clear deficit:
- 1. in functional ability or autonomy
- 2. in motor function
- 3. in cognitive capacities
- 4. in language
- A systemic disease with neurological symptoms
- A life threatening disease with life expectancy of less than 1 year
- Renal insufficiency (creatinine > 2 mg/100 ml or > 180 µmol/l; creatinine had to be determined as soon as possible but not before inclusion)
- Any concomitant treatments that could not be stopped at the moment of inclusion or that had been started after the onset of the stroke and before inclusion (as long as not considered by the advisory board as effective drug), such as:
