5. Study Description

Brief Summary
This an open label study to assess the pharmacokinetics of CT1812 in normal healthy volunteers.
Detailed Description
Open label study to assess PK in 36 older healthy volunteers. Subjects will be screened 35 days prior dose to determine eligibility. On day -1 subjects will be admitted to the clinical research unit and on day 1 will be randomized to receive one of the following doses: 150 mg BID, 150 mg QD or 300 mg QD in the fed state. Subjects will be confined in the Clinical Research Unit where they will continue to receive study drug and complete safety assessments, PK and CSF draws, until day 16 when they will be discharged.
