|Brain Injuries, Traumatic||Drug: Glucose Drug: Lactate Drug: Beta-hydroxybutyrate||Phase 1 Phase 2|
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 safety analysis of glucose and sodium lactate infusions in humans and have demonstrated proof of concept that these fuels alter brain metabolism. Animal TBI studies have demonstrated proof of concept for all three candidate fuels. We will conduct a multicenter, adaptive design-based, proof of concept unblinded phase 2 study of up to 3 candidate supplemental fuels infused over 3 hours in patients with severe TBI undergoing standard of care multimodality monitoring with cerebral microdialysis. The three candidate fuels are be glucose, sodium lactate, and beta-hydroxybutyrate, with doses to be established in animal models. Infusions will be guided by point of care testing to achieve the ideal blood concentration during the infusion during the infusion.
This is a 5-year safety study using a parallel intervention model with 4 arms, open-label, non-randomized.

Standard of Care
Infusion of glucose as supplemental fuel (dosage form = solute, dosage to be determined, frequency = 1x, duration = 3hr)
Less than one fifth of one ounce of glucose mixed in standard saline solution will be administered through a standard venous drip line or through the microdialysis catheter as part of standard brain chemistry analyses.
Infusion of sodium lactate as supplemental fuel (dosage form = solute, dosage TBD, frequency = 1x, duration = 3hr)
Less than two thirds of an ounce of lactate mixed in standard saline solution will be administered through a standard venous drip line or through the microdialysis catheter as part of the standard brain chemistry analyses.
Other Name: Sodium lactate
Infusion of beta-hydroxybutyrate as supplemental fuel (dosage form = solute, dosage TBD, frequency = 1x, duration = 3hr)
Less than one tenth of one ounce of hydroxybutyrate mixed in standard saline solution will be administered through a standard venous drip line or through the microdialysis catheter as part of the standard brain chemistry analyses.
