Study Overview
Brief Summary
The study will be conducted as a single-center, randomized, double-blind, placebo-controlled, ascending dose study in up to 8 sequential cohorts of healthy subjects. Each cohort will enroll 8 subjects: 6 subjects will receive ITI-333 and 2 subjects will receive placebo as a single oral dose after a fast of at least 10 hours.

- •BMI inclusive of 18-32 kg/m2 at screening and a minimum weight of 50 kg;
