Fluorine F 18 Sodium Fluoride Positron Emission Tomography in Evaluating Response to Dasatinib in Patients With Prostate Cancer and Bone Metastases

Description:

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.

Isotope(s):
Target(s):
  • Bone Metabolism
Ligand Class: Small Molecules
Inclusion
  • Men 18 years or older with metastatic castration-resistant prostate cancer enrolling onto the Febbo clinical trial with dasatinib therapy (must meet all inclusion criteria for dasatinib treatment study and comply with requirements of that specific clinical trial)
  • * Must be able to provide a written informed consent
  • Histologic confirmation of original prostate cancer diagnosis
  • Presence of at least one convincing bone metastasis as defined by bone scintigraphy, computed tomography (CT) scan (magnetic resonance imaging \[MRI\] if indicated), or plain X-ray
  • Must currently have castrate testosterone levels (\< 50 ng/dL) from orchiectomy or maintenance on a luteinizing hormone-releasing hormone (LHRH) agonist or LHRH antagonist
Exclusion
  • A serious underlying medical condition that would otherwise impair the patient's ability to receive treatment and imaging studies
  • Expected lifespan of 12 weeks or less
  • Note: However, if a patient crosses-over from nilutamide at the time of progression to add dasatinib therapy, he may be eligible for 18F-fluoride PET imaging protocol if he meets all inclusion criteria for this trial
  • Any condition that would alter the patient's mental status, prohibiting the basic understanding and/or authorization of informed consent
  • * On the nilutamide-only arm (Arm A of the clinical therapeutic trial)
