A Phase 4, Randomized, Open-label, Multicenter Efficacy and Safety Study of Standard Dose of Radium-223 Dichloride vs. Standard Doses of Novel Anti-hormonal Therapy (NAH) in Patients With Bone Dominant Metastatic Castration Resistant Prostate Cancer (mCRPC) Progressing on/After One Line of NAH

Description:

Participants in this study will receive either Radium-223 dichloride or a NAH therapy. Radium-223 dichloride will be given as an infusion into one of the veins on Day 1 of each 4-week cycle for a total of up to 6 cycles. Oral NAH therapy will be given per the standard approved dose once daily until the disease has progressed. Participants will visit the hospital or clinic every 2 weeks for the first 6 cycles, and only on the first day of each cycle from cycle 7 and onwards. Observation for each participant will last for about 2 years in total. Blood and urine samples will be collected from the participants and participants will be asked to complete questionnaires about the well-being and the pain.
