Novartis ( Novartis Pharmaceuticals )
ClinicalTrials.gov Identifier:
NCT01528241
First received: February 3, 2012

  Purpose
This study is designed to characterize the regional distribution of [11C] ABP688 in brain by positron emission tomography (PET).

Condition Intervention Phase
Depression Drug: ABP688 Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: A Multi-center, Open-label Study in Elderly Healthy Volunteers and Elderly Patients With Major Depressive Disorder to Characterize the Regional Distribution of [11C] ABP688 in Brain by Positron Emission Tomography (PET)

Further study details as provided by Novartis ( Novartis Pharmaceuticals ):

Primary Outcome Measures:
  • Binding of [11C] ABP688 to mGlu5 receptors [ Time Frame: Day 1 ]
    Binding of [11C]ABP688 will be determined using positron emission tomography (PET) for up to 90 minutes

  • Blood levels of [11C] ABP688 [ Time Frame: Day 1, up to 60 minutes ]
    Blood samples (up to 19 time points via indwelling catheter) will be collected for the determination of [11C] ABP688. Specific times are recorded at the clinical site.


Secondary Outcome Measures:
  • Difference in [11C]ABP688 binding to mGlu5 receptors [ Time Frame: Day 1 ]
    Using data generated as described above, data will be analyzed to determine if there are difference in binding between healthy volunteers and patients.


Enrollment: 42
Study Start Date: August 2008
Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ABP688
Elderly MDD patients and demography matched healthy volunteer
Drug: ABP688
Carbon 11 labeled ABP688 will be administered intravenously as a slow intravenous push.
