A Study to Examine the Distribution of PF-06372865 in the Brain of Healthy Volunteers Using Positron Emission Tomography and a Radioactive Tracer Following Oral Administration of One Dose of PF-06372865

September 23, 2014 updated by: Pfizer

A Phase 1, Open-label Study To Evaluate Central Occupancy Of The Benzodiazepine Binding Site Of Gabaa Receptors By Positron Emission Tomography (Pet) With Ligand [11c]Flumazenil Following Single Dose Of Pf-06372865 In Healthy Subjects

This study will see how PF-06372865, an experimental drug distributes in the brain after one dose of PF-06372865 is administered orally to healthy volunteer subjects. The study will also evaluate the safety and tolerability of PF-06372865in these subjects and will measure the level of PF-06372865 in the blood.
