Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to compare the clinical benefit of radium-223 dichloride versus placebo in combination with abiraterone and prednisone/prednisolone in asymptomatic or mildly symptomatic chemotherapynaïve bone predominant metastatic castration-resistant prostate cancer patients.;Secondary Objective: The secondary objectives are to compare overal survival, time to opiate use for cancer pain, time to pain progression, time to cytotoxic chemotherapy, radiological progression free survival, acute and long term safety.;Primary end point(s): Symptomatic skeletal event free survival(SSE-FS);Timepoint(s) of evaluation of this end point: At 3 years | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Overall Survival 2. Time to opiate use for cancer pain 3. Time to pain progression 4. Time to cytotoxic chemotherapy 5. Radiological progression free survival (rPFS) 6. Number of participants with adverse events as a measure of safety and tolerability;Timepoint(s) of evaluation of this end point: 1. At 3 years for interim At 6 years for final 2. At 3 years 3. At 3 years 4. At 3 years 5. At 3 years 6. Up to 3 years | — |
