NCT02776488

Brief Summary

Metabolic crisis is a state of energy insufficiency due to impaired mitochondrial function as indicated by cerebral microdialysis lactate/pyruvate ratio (LPR). We have performed preliminary mechanistic analysis of alternative fuels in humans and have demonstrated proof of concept that exogenous fuels alter brain metabolism. We will conduct a multicenter, adaptive design-based, proof of concept phase 2 safety study of candidate supplemental fuels in patients with severe traumatic brain injury to determine safety and efficacy.
