Castration-Resistant Prostatic Cancer

Pain evaluation in Radium-223 treated castration resistant prostate cancer patients with bone metastases

Trial purpose

This observational prospective single arm cohort study is designed to assess pain and bone pain related quality of life of metastatic Castration Resistant Prostate Cancer (mCRPC) patients receiving Radium-223 in a real life nuclear medicine practice setting. In addition, overall survival, time to next tumor treatment (TTNT), time to first symptomatic skeletal event (SSE), course of blood counts, and safety will be assessed.

Primary Outcome

  • Pain response
    Determined by the worst pain item on the Brief Pain Inventory – Short Form (BPI-SF) patient questionnaire. A clinically meaningful pain response is defined as an improvement of two points from the baseline BPI-SF worst pain score at any post-baseline assessment.

    Up to 6 months
    enhanced_encryption
    Safety Issue:
    No

Secondary Outcome

  • Change of pain over time
    Determined by evaluating the worst pain item as well as the subscale scores for pain severity and pain interference as determined by patient responses on the BPI-SF questionnaire.

  • Pain control rate
    As determined by the worst pain item on the BPI-SF patient questionnaire. Pain control is defined as no increase by two points from the baseline BPI-SF worst pain score.

    Safety Issue:
    No
  • Pain progression rate
    As determined by the worst pain item on the BPI-SF patient questionnaire. Pain progression is defined as an increase by two points from the baseline BPI-SF worst pain score at any post baseline assessment.
    date_rangeTime Frame:
    Up to 6 months
    enhanced_encryption
    Safety Issue:
    No
  • Time to first pain progression
    Defined as the time between the first injection of Radium-223 until an increase in the BPI-SF worst pain item by at least two points
