A Study To Examine The Distribution Of PF-05212377 In The Brain Of Healthy Volunteer Subjects Using Positron Emission Tomography And A Radioactive Tracer Following Oral Administration Of One Dose Of PF-05212377

April 15, 2014 updated by: Pfizer

A Phase 1, Open-Label Study To Evaluate 5-HT2a Receptor Occupancy As Measured By Positron Emission Tomography (PET) With Ligand [11C]MDL100907 Following Single Oral Dose Administration Of PP-05212377 (SAM-760) In Healthy Subjects

This study will see how PF-05212377, an experimental drug to treat symptoms from Alzheimer's Disease, distributes in the brain after one dose of PF-05212377 is administered orally to healthy volunteer subjects. The study will also evaluate the safety and tolerability of PF-05212377 in these subjects and will measure the level of PF-05212377 in the blood.
