An Open Label Positron Emission Tomography (PET) Study to Determine Central mGluR5 Receptor Occupancy of AZD2516

This study has been completed.
Information provided by:
AstraZeneca Identifier:
First received: April 28, 2009
Last updated: October 27, 2009
Last verified: October 2009
The purpose of this study is to determine if AZD2516 binds to mGluR5 receptors in the brain. This will then help to make accurate predictions of efficacy and dosing in the future development programme.

Condition Intervention Phase
Healthy Drug: AZD2516 Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: An Open Label Positron Emission Tomography (PET) Study With [11C]AZ12713580 to Determine Central mGluR5 Receptor Occupancy of AZD2516 After Oral Administration to Healthy Subjects

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Positron emission tomography to determine if AZD2516 can displace the radioligand [11C]AZ12713580 and describe relationship between AZD2516 exposure and mGluR5 receptor occupancy [ Time Frame: 1 Month: Baseline and 3 PET examinations ]

Secondary Outcome Measures:
  • Safety and tolerability of AZD2516 by adverse events, vitals signs, ECG, body temperature and laboratory variables [ Time Frame: Assessed at each visit from baseline to follow-up visit ]
  • To investigate the Pharmacokinetics of AZD2516 [ Time Frame: 1 Month: 3 doses AZD2516 and 16 planned PK samples after each dose ]
