A Study To Assess Effects Of PF-04958242 On Bold Functional Magnetic Resonance Imaging During Working Memory Activation And Arterial Spin Labeling At Rest In Healthy Subjects

• Status: Completed
• Trial end date: 2012-12-14
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of this study aims to determine whether the drug affects brain activity in healthy volunteers, either when the participants are performing a memory task, or when lying at rest. Subjects will undergo a brain scan under both of these conditions after a dose of either the study drug or a placebo is administered.The secondary objective is to evaluate the safety and tolerability of the four doses of PF-04958242 administered orally to healthy adult participants.

• Phase: Phase 1
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers
