NCT00788801

Brief Summary

This study is being done in healthy volunteers to help researchers understand how ABT-614 works in the human body, specifically in the brain. The PET imaging technique can be thought of as a way to take pictures of chemical changes in the brain. To take a PET scan (picture), a substance with low levels of radioactivity (radiotracer) has to be injected when you are in the PET camera. The radiotracer is only radioactive for a short period of time. In this study, PET is being used to measure how the study drug attaches to specific receptors in the brain. The radiotracer used in this study, \[11C\]-(+)-PHNO, is currently being used for studies in people at the CAMH PET Centre.

Eligibility Criteria

Age18 Years - 40 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Body Mass Index (BMI) is 18 to 26 kg/m2, inclusive
  • A condition of general good physical health based upon the results of a medical history, physical examination, vital signs, laboratory profile, 12-lead electrocardiogram (ECG)

You may not qualify if:

  • Presence of a metal implant (i.e., aneurysm clip, metal fragments, internal electrical devices such as a cochlear implant, spinal cord stimulator or pacemaker) that would preclude a MRI scan
  • During the last year, a radiation exposure that on its own or in addition to the expected radiation from this study exceeds the allowed annual radiation exposition level (20 mV)
  • Use of tobacco or other nicotine-containing products within 6 months prior to Screening
  • Diagnosis of substance or alcohol disorder within 12 months prior to Screening
  • History of claustrophobia or feeling of inability to lie still on his back in the PET camera
  • History or presence of any neurological or psychiatric conditions
