Primary outcome measureTo evaluate the safety of different doses of XY2405 when used as a treatment for acute traumatic brain injury in order to inform dose selection for a phase III trial
Secondary outcome measures1. To assess the effect of XY2405 on mortality, morbidity and biomarkers of blood brain barrier dysfunction among patients with acute traumatic brain injury. Mortality will be assessed two weeks following the injury. In-hospital morbidity will be assessed two weeks post injury.
2. To assess pharmacokinetic (PK) profile in a larger population of patients
