TBI is a serious public health problem that affects more than 1.7 million Americans each year. Despite significant efforts in more than 75 clinical trials over the past 20 years, there is still no approved treatment for TBI.

Previous research has shown progesterone exerts its neuroprotective effects by protecting or rebuilding the blood-brain barrier, decreasing development of cerebral edema (brain swelling), down-regulating the inflammatory cascade and limiting cellular necrosis and apoptosis (programmed cell death).

Building on the SyNAPSe study of BHR-100 and promising research conducted by Emory University, BHR is also developing BHR-310, an intranasal progesterone powder. This nasal spray is being evaluated as a potential treatment that can be administered to wounded warriors or athletes with TBI quickly after injury on the battlefield or playing field. Preclinical studies of BHR-310 in rats and monkeys support the feasibility of a high-dose, rapidly absorbed intranasal progesterone product able to deliver clinically meaningful doses of progesterone to the brain.
