Pharmacokinetic and Metabolic Profile of Deutetrabenazine (TEV‐50717) Compared With Tetrabenazine in Healthy Volunteers

Deutetrabenazine (Austedo, Teva Pharmaceuticals) is a deuterated form of tetrabenazine. It is the first deuterated drug to receive US regulatory approval and is approved for treatment of chorea in Huntington’s disease and tardive dyskinesia. Two oral single dose studies comparing deutetrabenazine (2...

description Deutetrabenazine (Austedo, Teva Pharmaceuticals) is a deuterated form of tetrabenazine. It is the first deuterated drug to receive US regulatory approval and is approved for treatment of chorea in Huntington’s disease and tardive dyskinesia. Two oral single dose studies comparing deutetrabenazine (25 mg) with tetrabenazine (25 mg) in healthy volunteers evaluated the impact of deuteration on pharmacokinetics of the active metabolites, alpha‐dihydrotetrabenazine (α‐HTBZ) and beta‐dihydrotetrabenazine (β‐HTBZ), metabolite profile, safety, and tolerability. In the two‐way, cross‐over study, the mean elimination half‐life of deuterated total (α + β)‐HTBZ was doubled compared with nondeuterated total (α + β)‐HTBZ, with a twofold increase in overall mean exposure (area under the concentration‐time curve from zero to infinity (AUC(0–inf))) and a marginal increase in mean peak plasma concentration (C(max)). In the mass balance and metabolite profiling study, there were no novel plasma or urinary metabolites of [(14)C]‐deutetrabenazine relative to [(14)C]‐tetrabenazine. Specific deuteration in deutetrabenazine resulted in a superior pharmacokinetic profile and an increased ratio of active‐to‐inactive metabolites, attributes considered to provide significant benefits to patients.
