Neurocrine Biosciences (NBIX) said Thursday it presented head-to-head data showing Ingrezza delivered greater potency compared with Teva Pharmaceutical's (TEVA) Austedo XR after a single dose of treatment for involuntary movement disorders.
The company said Ingrezza capsules achieved "significantly higher" vesicular monoamine transporter 2 target occupancy, which measures drug response level in involuntary movement disorders, including tardive dyskinesia and Huntington's disease chorea.
All doses of both Ingrezza and Austedo XR were generally well-tolerated and consistent with their safety profiles, Neurocrine said.
Shares of Neurocrine were down more than 1% in recent trading Thursday.
