Study Evaluating Safety, Tolerability, Pharmacokinetics and 5 HT1A Receptor Occupancy

July 7, 2008 updated by: Wyeth is now a wholly owned subsidiary of Pfizer

A Positron Emission Tomography Study to Assess the Level and Duration of Occupancy of Serotonin-1A Receptors Produced by Single Oral Doses of SRA-444 in Healthy Elderly Subjects and in Subjects With Alzheimer Disease

The study will include a preliminary pharmacokinetics (PK) / safety / tolerability evaluation in healthy elderly subjects followed by the Receptor Occupancy (RO) evaluations in healthy elderly subjects and in Alzheimer's Disease (AD) subjects.
