AbstractDespite prodigious advances in TBI neurobiology research and a broad arsenal of animal models mimicking different aspects of human brain injury, this field has repeatedly experienced collective failures to translate from animals to humans, particularly in the area of therapeutics. This lack of success stems from variability and inconsistent standardization across models and laboratories, as well as insufficient objective and quantifiable diagnostic measures (biomarkers, high-resolution imaging), understanding of the vast clinical heterogeneity, and clinically centered conception of the TBI animal models. Significant progress has been made by establishing well-defined standards for reporting animal studies with "preclinical common data elements" (CDE), and for the reliability and reproducibility in preclinical TBI therapeutic research with the Operation Brain Trauma Therapy (OBTT) consortium. However, to break the chain of failures and achieve a therapeutic breakthrough in TBI will probably require the use of higher species models, specific mechanism-based injury models by which to theranostically targeted treatment portfolios are tested, more creative concepts of therapy intervention including combination therapy and regeneration neurobiology strategies, and the adoption of dosing regimens based upon pharmacokinetic-pharmacodynamic (PK-PD) studies and guided by the injury severity and TBI recovery process.
