Cooling Plus Best Medical Treatment Versus Best Medical Treatment Alone for Acute Ischaemic Stroke (EuroHYP-1)

EuroHYP-1: European Multicentre, Randomised, Phase III Clinical Trial of Therapeutic Hypothermia Plus Best Medical Treatment Versus Best Medical Treatment Alone for Acute Ischaemic Stroke

The purpose of this study is to determine if systemic cooling to a target temperature of 34 to 35°C, started within 6 hours of symptom onset and maintained for 12 hours, improves functional outcome at 3 months in patients with acute ischaemic stroke.

  • Possibility to start therapeutic hypothermia within 6 hours after onset of stroke
  • Possibility to start therapeutic hypothermia within 150 minutes after start of alteplase administration in patients receiving thrombolysis at the trial site or within 150 minutes after start of endovascular treatment, if this is later
  • Possibility to start therapeutic hypothermia within 150 minutes after admission to trial site in patients not receiving thrombolysis or in patients who have received thrombolysis at a different site
  • mRS score ≤2 prior to onset of stroke
  • NIHSS score ≥6

Exclusion Criteria:

  • Use of monoamineoxidase inhibitors in the 14 days prior to screening

  • Rapidly resolving stroke symptoms
  • Evidence from CT or MRI of intracranial haemorrhage or tumour or encephalitis or any diagnosis likely to cause the present symptoms other than acute ischaemic stroke. Haemorrhagic transformation of the infarct is not an exclusion criterion, except when there is a parenchymal haematoma covering more than 30% of the infarcted area, with significant space-occupying effect, or when there is a bleeding remote from the infarcted area

  • Known renal impairment (serum creatinine >2mg/100ml)
  • Addison's disease
  • Any other condition that may interfere with, or be aggravated by, therapeutic hypothermia
  • Any condition that is thought to reduce the compliance to cooperate with the trial procedures

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control
Best medical treatment
Experimental: Hypothermia
Best medical treatment + hypothermia 34-35°C for 24h
In patients randomised to therapeutic hypothermia, induction of cooling will be started by infusion of 4°C isotone saline or Ringer's lactate administered over a period of 30 to 60 minutes. A body temperature between 34.0 and 35.0°C will be targeted. Body temperature will be monitored through bladder or rectal thermal probes, and cooling procedures will be adapted to keep body temperature as close as possible to the target. Maintenance of body temperature in the target range will be performed with a surface or endovascular cooling device. After a cooling period of 24h, controlled rewarming to 36°C with a rate of 0.2°C/h will be started. After 36°C have been reached, the device will be disconnected.
