The goal of this study is to visualize biodistribution of a PET tracer called [18F]F-AraG through time in healthy human volunteers.

Condition Intervention Phase
Cancer Drug: [18F]F-AraG Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Study of the Kinetics, Dosimetry and Safety of [18F]F-AraG, a Positron Emission Tomography Tracer for Imaging the Activation of the Immune System in Healthy Humans

Further study details as provided by CellSight Technologies, Inc.:

Primary Outcome Measures:
  • Visualize biodistribution of the PET tracer [18F]F-AraG [ Time Frame: 1 day ]
    Whole-body [18F]F-AraG PET scans will be performed at 4 different time points following intravenous injection of the PET tracer. Four whole-body images will be obtained that will reveal biodistribution of [18F]F-AraG at 4 different consecutive time points after intravenous injection.

  • Analyze human dosimetry of [18F]F-AraG [ Time Frame: 1 day ]
    Time-Activity curves will be graphed by measuring activity in various organs at the 4 time points after tracer injection. From these time activity curves absorbed radiation will be calculated.

  • Assess acute safety of intravenously injected trace dose of [18F]F-AraG [ Time Frame: 8 days ]
    Blood and urine samples may be collected at baseline and at 1 and 8 days after injection of [18F]F-AraG to perform metabolic panel, CBC and urine analysis. Vital signs and EKG will be measured and recorded at baseline, within 3 hours after tracer injection and at 1 and 8 days after tracer injection.

Estimated Enrollment: 30
Study Start Date: February 2015
Estimated Study Completion Date: December 31, 2017
Estimated Primary Completion Date: December 31, 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 18F-FAraG
A single dose intravenous injection of 18F-FAraG followed by PET scanning.
Drug: [18F]F-AraG

Detailed Description:
A positron emission tomography (PET) imaging tracer will be intravenously injected into healthy human volunteers who provide informed consent. Following injection of this tracer each volunteer will have four whole-body PET scans inside a PET scanner to obtain images of tracer biodistribution at four different time points. This will allow studying the kinetics of the tracer as well analysis of tracer dosimetry. Safety of the tracer will also be analyzed in each volunteer.
