Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Primary aim: To measure [18F]ciprofloxacin pharmacokinetics in bone metastases of HRPC patients before and after imatinib mesylate therapy with PET. ;Secondary Objective: Secondary aim: To assess the test-retest variability of the [18F]ciprofloxacin/PET procedure. ;Primary end point(s): • Total [18F]ciprofloxacin concentrations in HRPC bone metastases measured from 0 to 2 hours after radiotracer injection and expressed as the area under the time-activity curve (AUCPET) in the region of interest defined in the PET image. • Test-retest variability for [18F]ciprofloxacin given as percent difference of AUCPET between measurement 1 and 1additional. • Difference in AUCPET before and after treatment with imatinib mesylate: ? AUCtumor= AUCPET before treatment - AUCPET after treatment. | — |
