Hyperbaric Oxygen Brain Injury Treatment (HOBIT) Trial
Gaylan Rockswold
Summary
The purpose of this innovative adaptive phase II trial design is to determine the optimal combination of hyperbaric oxygen treatment parameters that is most likely to demonstrate improvement in the outcome of severe TBI patients in a subsequent phase III trial.
Description
Preclinical and clinical investigations strongly indicate that hyperbaric oxygen (HBO2) is physiologically active in improving the destructive processes in severe Traumatic Brain Injury (TBI). However, prior to a definitive efficacy study, important information is required regarding optimizing the HBO2 treatment paradigm instituted in terms of pressure and whether NBH enhances the clinical effectiveness of the HBO2 treatment. Preclinical investigators working with TBI models have used pressures varying from 1.5 to 3.0 atmospheres absolute (ATA). Clinical investigators have used pressure varyin…
