Traumatic Brain Injury

According to the Department of Defense Personnel and Procurement Statistics, 75% of all U.S. military casualties of Operation Enduring Freedom and Operation Iraqi Freedom are caused by explosive weaponry, resulting in TBIs and blast-induced neurotrauma, which have been called the “signature wounds” of these wars.  They estimate that TBI accounts for about 22 percent of all casualties.  In a January 2006 report, the Centers for Disease Control (CDC) estimated that 1.4 million U.S. civilians sustain TBI each year.  Of them, about 50,000 die, 235,000 are hospitalized and 1.1 million are treated and released from an Emergency Department.  An estimated 80,000-90,000 people with TBI experience permanent disability from their injury.  These incidence rates have led the CDC to conclude that TBI prevention, improved acute care and rehabilitation to reduce the likelihood of TBI-related disability, and increased access to services for those who do not fully recover must continue to be national priorities.

We are conducting Phase IIb clinical trials in Switzerland and Israel with our Oxycyte PFC emulsion.  Our study is a double-blind, placebo controlled dose-escalation study designed to evaluate the safety, efficacy and dosing parameters of Oxycyte PFC, a novel perfluorocarbon emulsion that is given intravenously to traumatic brain injury patients.  The study protocol calls for three dose cohorts (1-3mL per kg body weight).  The study’s first cohort has been completed and the database has been locked.  The second cohort has been approved by DSMB. Currently, we are considering revising protocol to include moderate/mild TBI patients in trial and are gearing up our manufacturing process to meet the needs of our trials.  We anticipate initiating the second cohort in 2012.
