Synthetic Blood Announces Positive Results from Traumatic Brain Injury Preclinical Study
In the study "Perfluorocarbon Emulsion Improves Cognitive Recovery Following Lateral Fluid Percussion Brain Injury in Rats," rats administered Oxycyte at 4.5ml/kg and 9.0ml/kg dose levels showed significantly better performance in the water maze test and had fewer dying neurons in the brain than control animals treated with a saline solution. Additionally, the group receiving Oxycyte at the higher dose maintained mean arterial blood pressure at a relatively higher level, which could indicate a further improvement in the cerebral blood flow after traumatic brain injury.
“Oxycyte has already proven safe in human clinical trials and, as a PFC emulsion with an extremely small average droplet size, it may be able to oxygenate tissues with narrow or occluded capillaries, such as those that occur in brain injury.”
"We proved our study hypothesis that the PFC emulsion Oxycyte would increase the solubility of oxygen in the blood and thus improve oxygen delivery to the acutely injured brain following traumatic brain injury," said Ross Bullock, M.D., Ph.D., Department of Neurosurgery at Virginia Commonwealth University School of Medicine and co-author of the study. "Taken together, the results of this study suggest that Oxycyte may represent an extremely promising avenue for future therapy in human severe traumatic brain injury."
"Results of this study support our efforts to proceed with clinical development of Oyxcyte for this indication," said Robert Nicora, Synthetic Blood President and CEO. "Oxycyte has already proven safe in human clinical trials and, as a PFC emulsion with an extremely small average droplet size, it may be able to oxygenate tissues with narrow or occluded capillaries, such as those that occur in brain injury."
The Company indicated that the eight-patient, open label Phase II proof-of-concept trial in traumatic brain injury will be conducted at the Virginia Commonwealth University Medical Center. The primary purpose of this study will be to demonstrate Oxycyte's ability to increase brain oxygen tension and favorably affect other brain chemistries that impact clinical outcome in patients suffering severe head injury. If the results are positive, the Company plans to start a larger Phase II trial, subject to the availability of additional financing, that will look at clinical outcome as well as biochemical changes in the brain.
