Traumatic Brain Injury Model

Traumatic Brain Injury (TBI) in the United States

  • 2.4 Million new cases annually (2009)

  • 50,000 deaths annually

  • 5.3 Million living with disabilities

  • $75 Billion economic toll in a single year

  • Traumatic brain injury (TBI) is a major risk factor for developing Alzheimer’s Disease

30 Clinical Trails for neuroprotective treatments of Traumatic Brain Injury (TBI) have failed since 1993.

Pre-Clinical Drug Screening

drug screening

Failed Approach: Target-based high throughput screening (HTS)

  • Lead discovery is based on activity against molecular targets

  • Target must be known

  • Theory is often wrong

  • Unlikely to discover compounds acting via novel biological mechanisms


neurons

Better Approach: Functional screening with organotypic slice or dissociated cell cultures

  • Directly assess neuroprotective properties in tissue of interest

  • Target does not need to be known

  • Directly assess subtle cell function through electrophysiological measurements

  • Normalization of post-injury to pre-injury level

  • Built-in internal control


MEASSuRE Enables Functional Drug Screening of Neuroprotective Compounds

MEASSuRE’s Advantage in Traumatic Brain Injury (TBI) Drug Discovery

  • Screen leads based on electrophysiological tissue response to stretch (injury)

  • No need to know target

  • Find novel biological mechanism

  • Eliminate drug candidates earlier in the pre-clinical development

  • Avoid rejecting potential drug candidates

  • Save time, money, and research animals by reducing the number of in vivo tests
