Optimal Brain Oxygenation in Neurologic Intensive Care Unit : The NeurO2

Status Recruiting

Clinical Trial Summary

The NeurO2 study is a multicenter observational study looking at NIRS monitoring in neurocrocritically ill patients during the acute phase of care following an acute brain injury. The study is nested within the HEMOTION Trial and the SAHaRA Trial

Clinical Trial Description

The NeurO2 study is a multicenter prospective study nested within two large-scale pragmatic randomized open blinded endpoint (PROBE) trials in neurocritically ill patients, the HEMOTION and the SAHaRa trials. These two trials are designed to compare a restrictive and a liberal transfusion strategies in critically ill patients with traumatic brain injury or subarachnoid hemorrhage. The NeurO2 will report on prospectively gathered regional cerebral oxygenation data (rSO2) from enrolled patients randomized to either the liberal or restrictive RBC transfusion strategy of their parent trials. The primary outcome will be 6-month neurologic function based on the GOSe. The established infrastructure of the trials will be used, including part of the data collection instruments and the outcome assessment team. The NeurO2 study will achieve three separate but interconnected primary objectives: i) Evaluate if the cerebral hypoxemic burden as measured by NIRS during NICU stay, is associated with functional neurologic outcome (Glasgow Outcome Scale extended - GOSe) at 6 months, ii) Determine if the cerebral hypoxemic burden is impacted by red blood cell transfusion, iii) Determine if the level of response in cerebral hypoxemic burden after RBC transfusion is associated with the 6-month functional neurologic outcome (GOSe) The secondary objectives are to evaluate whether the cerebral hypoxemic burden measured by NIRS is associated with other clinically relevant outcomes including ICU, hospital and 6-month mortality and hospital, ICU length of stay and quality of life. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
