Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Single arm
All subjects receive concurrent administration of Radium Ra223 Dichloride and Abiraterone Acetate plus Prednisone
|
Radium Ra 223 dichloride - A targeted alpha particle-emitting pharmaceutical (a radiopharmaceutical drug) is a ready-to-use solution for intravenous injection containing the drug substance radium dichloride.
The active moiety is the alpha particle emitting nuclide Ra-223, present as a divalent cation (223Ra2+) and Abiraterone Acetate - A CYP17 inhibitor, indicated in combination with prednisone for the treatment of subjects with metastatic castration-resistant prostate cancer.
Administration of Abiraterone Acetate may result in mineralocorticoid-related adverse events (AEs), due to CYP17 inhibition.
Therefore, Abiraterone Acetate is administered in combination with Prednisone to reduce the frequency of these AEs.
