Pharmacology

NSI-189 has been shown to increase the hippocampal volume of adult mice by 20%,[3] and has been shown to stimulate neurogenesis of human hippocampal stem cells in vitro and in vivo. The hippocampus is responsible for the consolidation of information from short-term memory to long-term memory, along with spatial navigation, and is also involved in regulation of mood.[2][4][5]

Clinical trials

NSI-189 successfully completed a phase 1 clinical trial in 2011 where it was administered to 41 healthy volunteers.[6]

A phase 1b clinical trial for treating major depressive disorder in 24 patients started in 2012 and completed in July 2014.[7][8] The study suggests that there were improvements in the patients' condition when the doses were 40/80 mg per day, but no significant improvements were seen for a higher dosage of 120 mg/day.

Neuralstem intends to pursue further clinical trials for a variety of neurological conditions, including major depressive disorder, traumatic brain injury, Alzheimer's disease, post-traumatic stress disorder,[2] stroke, and natural cognitive and memory decline in aging.[3]
