Essential Tremor (NBI-640756)

NBI-640756 is a novel molecule which was discovered in our laboratories. We have successfully completed a single site, randomized, double-blind, placebo-controlled sequential dose-escalation, Phase I safety and pharmacokinetics study of NBI-640756 given as a single oral dose in approximately 32 healthy volunteers. The study was conducted in multiple sequential cohorts of eight subjects per cohort. Based on the positive results of this initial Phase I study, we initiated a multiple ascending dose study of NBI-640756.

This second Phase I study is a single site, randomized, double-blind, placebo-controlled, multiple-dose, sequential dose-escalation study to evaluate the safety, tolerability and pharmacokinetics of NBI-640756 in healthy volunteers over a week of continuous dosing. This study is also being conducted in multiple sequential cohorts of ten subjects per cohort; data from this second Phase I study is expected in early 2017.

The data from both of these Phase I studies, as well as preclinical data will be evaluated and utilized in the design of the anticipated Phase II program for NBI-640756 in subjects with essential tremor.
