ClinicalTrials.gov Identifier: NCT03176186
Recruitment Status : Unknown
Verified March 2019 by NeuroproteXeon, Inc..

Brief Summary:
XePOHCAS: Prospective, randomized, multicenter interventional trial in adult subjects with out-of-hospital cardiac arrest comparing treatment with standard-of-care post-cardiac arrest intensive care (which is targeted temperature management [TTM]) to xenon by inhalation plus standard-of-care post-cardiac arrest intensive care (including TTM).

Condition or disease Intervention/treatment Phase
Post-Cardiac Arrest Syndrome Combination Product: Xenon Phase 3

Detailed Description:


Primary Objective:

To evaluate whether there is a difference in functional outcome with xenon 50% and oxygen during targeted temperature management (TTM) compared with similar oxygen content in air during TTM in comatose subjects with sustained restoration of spontaneous circulation (ROSC) within 30 minutes after out-of-hospital cardiac arrest (OHCA).

Secondary Objective:

To evaluate whether there is a difference in survival with xenon 50% and oxygen during targeted temperature management (TTM) compared with similar oxygen content in air during TTM in comatose subjects with sustained restoration of spontaneous circulation (ROSC) within 30 minutes after out-of-hospital cardiac arrest (OHCA).

Drug Information available for: Xenon

Arm Intervention/treatment
No Intervention: TH/TTM
Protocol-directed standard of care (including TH/TTM) dictated by the 2015 guidelines for Post-Cardiac Arrest Care from the American Heart Association and the European Resuscitation Council. Mechanical Ventilation delivered by individual site-sanctioned ventilator.
Active Comparator: TH/TTM plus Xenon
50% xenon gas in addition to standard of care, including therapeutic hypothermia/targeted temperature management (TH/TTM).
Combination Product: Xenon
50% xenon by inhalation, delivered by customized xenon delivery system, that includes a ventilator, for the 24h period of TH/TTM. The inhalation therapy is provided in combination with protocol-directed Post-Cardiac Arrest Care dictated by the 2015 guidelines from the American Heart Association and the European Resuscitation Council.
Other Name: XENEX

Primary Outcome Measures :
  1. functional outcome: degree of functional independence measured using a modified Rankin Scale (mRS) [ Time Frame: 30 days after the cardiac arrest ]
    The degree of functional independence will be measured using a modified Rankin Scale (mRS)

Secondary Outcome Measures :
  1. survival: number of survivors [ Time Frame: 30 days after the cardiac arrest ]
    The number of survivors will be measured
