White Lab

Under the direction of Fletcher White, MS, PhD, professor of Vergil K. Stoelting Chair of Anesthesia, the White Lab is located at the Stark Neurosciences Research Institute. Research in this lab focuses on the mechanistic development and chronicity of pain due to traumatic brain injury (TBI), peripheral nerve injury, polytrauma, chemotherapeutics and disease.

Treatments and therapeutic techniques that can be used to influence these mechanisms are in development and may have a positive impact on the lives of patients. An expert in neuroinflammation, White encourages researchers to apply immunology theory and principles of neuroscience to create translational therapies for clinical implementation.

Active Clinical Trials

The White Lab is conducting a clinical trial on the Role of Deficient Modulatory Systems in Chronic Post-Traumatic Headache after Mild Traumatic Brain Injury. In order to participate, individuals must be seen by an emergency medicine physician and/or staff at a trial-affiliated hospital, including IU Health Methodist, Sidney & Lois Eskenazi Hospital, and St. Vincent Hospital in Indianapolis.

  • Clinical Trial Participant Requirements
    • 18 – 59 years of age
    • Resident of Indianapolis and its surrounding communities
    • Diagnosis of mild traumatic brain injury as defined by the following:
    • Criteria recommended by the World Health Organization Task Force30: 1) Glasgow Coma Scale (GCS) score 13 – 15 when examined at an emergency medicine department listed above; 2) no abnormal findings on a computed tomography scan of the brain to exclude secondary disorders such as hematoma, cerebral vein thrombosis, cerebral hemorrhage or epilepsy; and 3) one or more of the following is present: confusion or disorientation, post-traumatic amnesia for < 24 hours, or loss of consciousness for > 30 minutes
  • Participant Exclusion Criteria
    • Manifestations of mild TBI must not be due to drugs, alcohol, medications, caused by other injuries or treatment for other injuries, caused by other issues such as psychological trauma or a coexisting medical condition, or caused by penetrating craniocerebral injury

    • Neurological disease (i.e. Parkinson’s disease, multiple sclerosis, epilepsy)
    • Serious psychiatric conditions (i.e. schizophrenia, bipolar disorder) or hospitalization within the preceding year for psychiatric illness
    • Chronic headaches prior to the head injury
    • No current involvement in litigation
