SAN DIEGO, Dec. 21 /PRNewswire-FirstCall/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced their highly selective vesicular monoamine transporter 2 (VMAT2) inhibitor, NBI-98854, will be advanced in clinical development. The first trial in human subjects, NBI-98854-0801, was a single ascending dose trial in healthy male volunteers conducted in Canada under an approved Clinical Trial Application (CTA) with Health Canada. Preliminary data have now been reviewed; NBI-98854 was generally safe and well tolerated. There were no Serious Adverse Events, clinically significant drug-related laboratory abnormalities or clinically significant ECG findings. More critically, the characteristics of the compound met the pre-specified pharmacokinetic requirements: dose proportionality, low maximum concentration (Cmax) with adequate area-under-curve (AUC) for drug exposure, low variability, and a half-life which supports once per day dosing.
