Conditions: Prostate Cancer
Keywords: Metastatic castrate-resistant prostate cancer bone metastasis
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 6
Healthy volunteers: no

Brief summary:
The purpose of this research study is to assess the effects of ZD4054 on prostate cancer that has spread to the bones by using new imaging techniques. In particular, this study will use fluorodeoxyglucose (FDG) and 18F-Sodium Fluoride (NaF) PET/computed tomography (CT) and MRI scans to look for changes in bone metastasis after ZD4054 therapy.

Detailed description:

Arms:
arm 1: ZD4054 + multimodal PET/MRI imaging

Interventions: intervention 1: ZD4054
Intervention descriptions: intervention 1: All patients will be treated with ZD4054 at 10 mg PO daily, repeated in four week cycles (1 cycle = 28 days). All patients will initially undergo NaF and FDG PET/CT and MRI imaging at baseline (scan#1), and then again after 4 weeks (scan#2) of ZD4054 exposure. Subsequently, ZD4054 will be held for 2 weeks followed by the final NaF and FDG-PET/CT and MRI acquisition (scan#3). After the final PET/MRI is obtained, patients will resume ZD4054 and be assessed for safety prior to each new cycle of therapy. Standard disease evaluation assessments will be conducted after cycle#3, and repeated after every third cycle (sooner if clinically indicated). Therapy will continue until radiographical/clinical disease progression or unacceptable toxicity
