|Condition or disease||Intervention/treatment||Phase|
|Out-of-hospital Cardiac Arrest||Procedure: Targeted temperature management to 33°C Procedure: Standard care with early treatment of fever||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||1900 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Triple (Participant, Investigator, Outcomes Assessor)|
|Masking Description:||The clinical team responsible for the participant (physicians, nurses and others) and involved with direct patient care will not be blinded to allocation group due to the inherent difficulty in blinding the intervention and as temperature is a vital sign required for clinical care. Measures will be taken to ensure that the information about allocation will not disseminate beyond the immediate group of caregivers responsible for patient care. A blinded physician will evaluate the patient at 96 hours after randomisation and make a statement on neurological prognosis.|
|Official Title:||Targeted Hypothermia Versus Targeted Normothermia After Out-of-hospital Cardiac Arrest (TTM2) - A Randomised Clinical Trial|
|Actual Study Start Date :||November 18, 2017|
|Estimated Primary Completion Date :||April 2022|
|Estimated Study Completion Date :||April 2022|
Active Comparator: Normothermia
Standard care with early treatment of fever. Active temperature control with a device will be used if the patient develops a temperature greater than or equal 37.8°C.
Procedure: Standard care with early treatment of fever
Normothermia and standard care - use of a device for temperature control if temperature is greater than or equal to 37.8°C
Targeted temperature management to 33°C for up to 28h.
Procedure: Targeted temperature management to 33°C
Rapid cooling to below 33°C, followed by temperature control at 33°C for up to 28h.

- Quality of Life [ Time Frame: 180 days ]Health-related Quality of Life - EQ-5D (VAS scale)
- Quality of Life [ Time Frame: 180 days ]Health-related Quality of Life - EQ-5D (Index value)
- Survival until end of the trial [ Time Frame: 180 days after randmomization of the last patient ]Mortality.
