E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To evaluate efficacy as measured by symptomatic skeletal event-free survival (SSE-FS) of radium-223 dichloride 50 kBq/kg (55 kBq/kg after implementation of NIST update) every 28 days for up to 6 doses compared to radium-223 dichloride 80 kBq/kg (88 kBq/kg after implementation of NIST update) every 28 days for up to 6 doses in subjects with CRPC metastatic to the bone not previously receiving radium-223 dichloride
• To evaluate efficacy as measured by SSE-FS of radium-223 dichloride 50 kBq/kg (55 kBq/kg after implementation of NIST update) every 28 days for up to 6 additional doses compared to no further radium-223 dichloride treatment in subjects with CRPC metastatic to the bone who previously received radium-223 dichloride 50 kBq/kg (55 kBq/kg after
implementation of NIST update) every 28 days for up to 6 doses, and survived SSE-free and are eligible for further radium-223 dichloride treatment. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate safety and tolerability
• To evaluate overall survival (OS)
• To evaluate pain improvement rate
• To evaluate time to pain progression
• To evaluate time to first SSE
• To evaluate time to radiological progression
• To evaluate radiological progression-free survival (rPFS)
• To evaluate change in analgesic use as measured by the Analgesic Quantification Algorithm (AQA). |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Histologically or cytologically confirmed adenocarcinoma of the prostate
- Castration-resistant disease defined as:
a Serum testosterone level: ≤ 50 ng/dL (1.7 nmol/L)
b Bilateral orchiectomy or maintenance on androgen ablation therapy with luteinizing-hormone-releasing hormone (LHRH) agonist or antagonist, or polyestradiol phosphate
c Serum PSA progression defined as 2 subsequent increases in PSA over a previous reference value, with a PSA value of
≥ 2 ng/mL at the time of the second increase
OR
Radiographic evidence of disease progression in bone (according to Prostate Cancer Clinical Trials Working Group 2 [PCWG2] criteria) with or without PSA progression
- Eastern Cooperative Oncology Group performance status (ECOG PS) 0 to 2. In case of ECOG PS 2, the PS has to be due to metastatic prostate cancer to the bone.

E.4 | Principal exclusion criteria |
- History of visceral metastasis, or visceral metastases
- Lymphadenopathy with lymph nodes exceeding 3 cm in short axis diameter
- Central nervous system (CNS) metastases
- Treatment with cytotoxic chemotherapy for prostate cancer within the previous 4 weeks prior to
randomization, or planned treatment with cytotoxic chemotherapy agents for prostate cancer during the
treatment period or follow-up
- Chronic conditions associated with non-malignant abnormal bone growth (e.g. confirmed Paget's disease of bone)
- Prior treatment with radium-223 dichloride
- Prior systemic radiotherapy and hemibody external radiotherapy |
