Response Evaluation of Cancer Therapeutics in Metastatic Castration-Resistant Prostate Cancer (mCRPC) to the Bone: A Whole Body MRI Study

This is an observational study and will not influence the choice of treatment. The treating clinicians will be able to use any clinical treatment regimen that is considered appropriated for the patient. This may include hormonal therapy or chemotherapy or therapy with radium-223. In addition, patients may be treated with bisphosphonates/denosumab, and granulocity-colony stimulating factor. The duration of therapy, doses, schedules, timing, premedication, patient monitoring during treatment, dose adjustments, and duration of therapy are entirely at the discretion of the treating clinician.

The use of radiotherapy is permitted, but the details including fields used must be communicated to the reporting radiologist to ensure this does not affect the interpretation of imaging. All other supportive or palliative treatments are permitted.

All patients will undergo imaging assessments as follows:

• At baseline, CT, BS (99mTc-MDP) and Whole Body-Magnetic Resonance Imaging (WB-MRI) will be performed.
• Follow-up imaging will be CT, BS and WB-MRI performed every 12 weeks until week 96, and then every 24 weeks until disease progression occurs or week 192.

Additional patient assessments to be performed include:
