Brief Summary:
This is a safety phase 2 clinical trial of intravenous infusion of sodium lactate in patients with severe TBI. This study is intended for patients in the acute setting in an intensive care unit at centers that have been selected to participate in this trial. This is a proof of safety study and biomarker response study.
Detailed Description:
Traumatic brain injury (TBI) consists of a primary localized insult to the brain followed by prolonged global disruption of brain metabolism, thus creating risk for secondary brain damage from energy deficiency. To date, there is no specific metabolic treatment to improve outcome after TBI. This study is designed to determine if providing a unique chemical fuel in the form sodium lactate will improve the brain's metabolism and prevent ongoing damage. Th investigators will seek to find the highest dose of sodium lactate that is tolerated and then to determine if administering this dose for 24 hours improves brain metabolism and survival. We will collect blood and brain MRI images to test if the intervention helps brain metabolism and brain structure. The study will be a randomized trial so that we have a comparison group against which to best evaluate safety. Ten medical centers that are very experienced with traumatic brain injury will participate in the study and will be supervised by a data safety monitoring board. This is a pilot study that will ultimately inform the design of a large scale clinical trial of sodium lactate in the near future.
RATIONALE TBI has no definitive drug treatment, and multiple trials have failed. We propose a pilot safety study of a metabolic treatment for TBI using exogenous sodium lactate (ELI) infusion to enhance brain oxidative metabolism as a medical treatment for TBI.
STUDY DESIGN This is a multicenter phase 2 study. The phase 2a study will identify the maximum tolerated dose of ELI using the continual reassessment dose escalation design with three dose tiers and will be followed by a phase 2b, randomized, placebo-controlled comparison of the ELI at maximum tolerated dose (MTD) for 24 hours vs normal saline infusion. The time to enrollment and start of study infusion will be 24 hours after onset of TBI.
PRIMARY OBJECTIVE The primary objective of part 1, the dose finding study is to determine the maximum tolerated dose (MTD) associated with a prespecified probability of dose limiting toxicity (DLT). The DLT is defined as the occurrence within 7 days of ELI of any one of three adverse events: AKI, arrythmia (atrial or ventricular tachycardia that causes hypotension), or ARDS (mild or greater).
The primary objective of the part 2 of the study, the randomized trial of MTD ELI for 24 hours vs saline is 30 day mortality.

Exclusion Criteria: Penetrating TBI, Polytrauma leading to instability of systemic hemodynamics, acidosis, or severe acute lung injury during the inclusion period. History of neurological disease, including Parkinson's, Huntington's, Alzheimer's, etc.; History of diabetes mellitus; Serum sodium ≥ 148 mM; Metabolic acidosis pH \<7.34; Coagulopathy INR \> 1.3, platelets \< 100,000, or hematocrit \< 28 mg/dl; Renal insufficiency with GFR \< 60% of expected or Cr \> 1.3; AST or ALT \> 1.5x upper limit of normal; Severe liver trauma; baseline serum lactate \> 2 mM; Hypotension SBP \< 90 refractory to vasopressors; Known mitochondrial genetic disorder; Pregnancy; Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data; Member of a protected population; simultaneous participation in another randomized trial
Time Window Enrollment and study infusion starts within 24 hours of TBI
TEST PRODUCT, DOSE, AND ROUTE OF ADMINISTRATION Sodium Lactate Injection, USP diluted to 200 mg/mL Sodium Lactate.
Lactate will be administered continuously for up to 6 hours by IV (in part 1) and for 24 hours (in part 2) and titrated to achieve targeted blood lactate concentrations for the assigned dose tier. New IND is pending. Investigational Product to be made by Altasciences.
