ABOUT NEPICASTAT (SYN117)

Nepicastat is an orally administered, potent and selective inhibitor of the enzyme dopamine beta-hydroxylase (DBH) which converts dopamine into norepinephrine. Like many other addictions, cocaine dependence is driven by dysregulation in the dopamine-reward system. Inhibition of DBH by nepicastat increases levels of dopamine, which may reduce craving for cocaine, and reduces the levels of norepinephrine, which may decrease the pleasurable responses to cocaine and the potential for stress-induced relapse following withdrawal. Biotie has previously conducted a placebo-controlled Phase 2a study in non-treatment seeking cocaine addicts. The study showed that nepicastat had a favourable safety profile and was well tolerated when administered with cocaine.

Nepicastat has also been evaluated as a potential treatment for post-traumatic stress disorder (PTSD). In December 2012, Biotie announced top-line data from an investigator-initiated Phase 2 study in PTSD. In this study, nepicastat was generally well tolerated but was not effective in relieving PTSD-associated symptoms when compared to placebo. Biotie is evaluating data from this study in further detail and will then decide on next steps with nepicastat in PTSD

Biotie holds full rights to nepicastat and will be able to use data from studies conducted with NIDA to support future potential regulatory submissions.
