Receptor Occupancy of LB-102 Using Positron Emission Tomography (PET) in Healthy Volunteers

This is a Phase 1, open label study designed to evaluate the dopamine receptor occupancy in healthy subjects. There will be 4 cohorts consisting of 4 subjects each. Eligible subjects will receive 1 or 2 doses of LB-102 on Day 1: subjects in the final cohort will be dosed for 5 days BID (ie twice/day) on an inpatient basis. This will be an open label study. Blood samples for pharmacokinetic (PK) and safety assessments will be collected at screening, immediately pre-dose, and during/before/after PET scan. Subjects enrolled in the inpatient cohort will be monitored daily. Follow-up after discharge will consist of a phone call the evening of discharge and the next day to check on subjects. This will be an adaptive study and doses in cohorts 2-4 will be determined after PET data from Cohort 1 are obtained.
