Allopregnanolone for the Treatment of Traumatic Brain Injury

Status Completed

Clinical Trial Summary

This study will provide initial data on the safety and effectiveness of allopregnanolone in improving neurobehavioral outcome and reducing mortality in adults with moderate and severe traumatic brain injury.

Clinical Trial Description

This is a double-blind, placebo-controlled, randomized, dose-finding, two-stage adaptive, clinical trial study comparing allopregnanolone to placebo when administered intravenously for 5 days beginning within 8 hours after injury. Test products to be administered are low and high dose allopregnanolone (Products L and H, respectively) and placebo (Product P) intravenous solutions. The products are administered during a 4-day treatment period followed by a 1-day dose de-escalation period. Stage 1 of the study will assess safety and confirm that dosing with Products L and H achieve the target steady-state plasma concentrations set for each of these products. Dosing will be adjusted in Stage 1, if necessary. Stage 2 will initially allocate subjects equally to Products L, H and P but will then use adaptive randomization to allocate subjects between Products L and H to optimized the probability of yielding a better 3-month Glasgow Outcome Score Extended (GOS-E) score. ;
