Use of Adipose-Derived Stem/Stromal Cells in Concussion and Traumatic Brain Injuries — C-TBI  

Concussion, Brain Clinical Trial

Official title: Use of Adipose-Derived Cellular Stromal Vascular Fraction (AD-cSVF) Parenterally in Post-Concussion Injuries and Traumatic Brain Injuries (TBI)

Status Withdrawn

Clinical Trial Summary

Concussion is the most common type of brain injury throughout life. Study is seeking improvement of long-term residua following adolescent and adult post-traumatic injuries often associated with contact sports and accidental causes. Typically defined as reversible head injury with temporary loss of brain function. Symptoms range from physical, cognitive, pain (headache) and emotional signs consistent with TBI and Post-Traumatic Stress Syndrome. Use of AD-cSVF parenteral delivery to encourage repair of damage and decreased function following concussion, particularly in contact, repetitive sports injuries. Range of damage is measured in Grade I-III according to graduated severity. Unfortunately, less information is available about repetitive concussions and the long-term health issues.

Clinical Trial Description

Concussion Syndrome (CS) and TBI are common injuries producing temporary and long-term damage to impact brain function. Symptoms are sometimes transient, sometimes long-term depending on severity and/or repetitive damage. Signs varying from recurrent headaches, mental fog, emotional changes to physical signs of loss of consciousness, amnesia to behavioral change (irritability, loss of concentration ability, etc.), cognitive impairment (slow reaction times, memory loss), and recurring sleep disturbances.

Common causes include sports injuries, automobile accidents, falls, blunt trauma to head, and explosive/blast injuries from production of acceleration injuries

Treatment often involves monitoring, physical rest, limiting cognitive activities (such as computing, video games, texting, and studying). Most often a single episode usually resolve or improve (particularly in recurring headaches) within 3-4 weeks. It is estimated that >6/1000 occurrence rate apply. Repetitive injuries seem to make the person more susceptible to additional damage, particularly with injury precedes resolution of an earlier damage. There appears also to make persons to require a lesser impact to produce the same degree of severity. It is becoming more recognized that repeated concussions increase the risks in later life for dementia, Parkinson's and severe depressions.

Most serious signs to evaluate are loss of consciousness, seizures, worsening headache, diplopia/pupil changes, loss of recognition, vomiting, focal neurological problems, and change of personality.

There is no consensus definition of concussion or TBI. Most concussions are considered in the mild TBI (mTBI) group, and are rarely demonstrate structural brain damage when in the acute to subacute state. Late brain MRI changes are difficult to clearly point to or identify the specific areas of presumed damage.

This study is intended to examine safety and efficacy of parenteral introduction of AD-cSVF in cases of CS and TBI, and categorically examine the outcomes according to the elapsed time from original concussive event. No delineation of those having recurrent damage and injuries are made within this study. ;
