NCT00690053
First received: June 2, 2008
Last updated: June 29, 2009

  Purpose
Non invasive imaging of hypoxia with the aid of PET-scans could help to select the patients having a hypoxic tumour who could be treated with specific anti-hypoxic treatments such as bio-reductive drugs or hypoxic radio-sensitizers. Several 2-nitroimidazoles to which the compound to be tested, HX-4, belongs, labelled with Fluor-18 have already been used in patients. However, bad image quality and unpredictable kinetics limit their use. In extensive pre-clinical models, the combination of HX-4 labelled with Fluor-18 is a promising non-toxic new probe to determine hypoxia.

Primary Outcome Measures:
  • Toxicity (CTCAE 3.0) [ Time Frame: 9 months ]

Secondary Outcome Measures:
  • Image Quality at different time points (Tumour-to-Background Ratio determined by PET-CT scan) [ Time Frame: 9 months ]

Estimated Enrollment: 12
Study Start Date: August 2008
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Procedure: Injection of HX-4
In step 1: 1 injection of HX-4 (max.6mCi (222MBq)) In step 2: 1 injection of HX-4 (max.12mCi 444MBq)

Detailed Description:

To determine the toxicity of the hypoxia PET-tracer [18F]-HX4 in cancer patients in two dose-steps:

  • Step 1 (3-6 patients): a single dose of maximum 6 mCi (222 MBq) dose of [18F]HX4 (which contains a maximum of 15 μg HX-4) via a bolus IV injection.
  • Step 2 (3-6 patients): a single dose of maximum 12 mCi (444 MBq) dose of [18F]HX4 (which contains a maximum of 27 μg HX-4) via a bolus IV injection.
