Clinical Trial Summary

This phase II trial is studying how well fluorine F 18 sodium fluoride positron emission tomography (PET) works in evaluating response to dasatinib in patients with prostate cancer and bone metastases. Diagnostic procedures, such as fluorine F 18 sodium fluoride PET, may help doctors predict a patient's response to treatment and help plan the best treatment.


Clinical Trial Description

PRIMARY OBJECTIVES:

I. Determine if changes in regional fluoride incorporation, measured by 18F-fluoride PET (SUV and Ki), occur in both castration-resistant prostate cancer bone metastases and normal bone as a response to treatment with dasatinib.

SECONDARY OBJECTIVES:

I. Determine if changes in 18F-fluoride transport (K1), an indicator of blood flow, and therefore, an indirect marker of angiogenesis, occur in both castration-resistant prostate cancer bone metastases and normal bone as a response to treatment with dasatinib.

OUTLINE: This is a multicenter study.

Patients undergo fluorine F 18 sodium fluoride PET scan at baseline and then at 12 weeks after initiation of treatment with dasatinib. PET parameters (SUV, Ki, and Kl) are also analyzed. ;
