Deutetrabenazine, also known as SD-809 and Tetrabenazine-d6, is an investigational, oral, small-molecule inhibitor of vesicular monoamine 2 transporter, or VMAT2, that is designed to regulate the levels of a specific neurotransmitter, dopamine, in the brain. Deutetrabenazine is a deuterated tetrabenazine. SD-809 is being developed for the treatment of chorea associated with Huntington’s disease, a neurodegenerative movement disorder that impacts cognition, behavior, and movements. Teva is investigating the broad potential of SD-809 for treating additional movements disorders such as tardive dyskinesia and tics associated with Tourette syndrome.
