E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the effects of sequential treatment between radium-223 and docetaxel on the percentage of symptomatic bone-only CRPC patients experiencing improvement or worsening in health-related quality of life (HRQoL). |

|
E.2.2 | Secondary objectives of the trial |
To compare survival in patients treated with sequential therapy between radium-223 and docetaxel and to identify predictive factors of Radium-223 for clinical outcome in this patient population. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients must have histologically or cytologically confirmed adenocarcinoma of prostate
2. Two or more bone metastases confirmed by bone scintigraphy within 4 weeks prior to study entry
3. Known castration-resistant disease, defined according to PCWG3 criteria as: castrate serum testosterone level: ≤50 ng/dL (≤1.73 nmol/L)
4. Subjects who have failed initial hormonal therapy, either by orchiectomy or by using a GnRH agonist in combination with an anti-androgen, must first progress through antiandrogen withdrawal prior to being eligible.

3. Progressione di malattia basata su un inequivocabile aumento del PSA e/o criteri radiografici
4. Malattia resistente alla castrazione, secondo i criteri PCWG3 per cui livelli di testosterone devono essere ≤50 ng/dL (≤1.73 nmol/L)
5. Pazienti che abbiano fallito un trattamento ormonale qualsiasi, incluso anche abiraterone e/o enzalutamide, che deve essere terminato almeno 4 settimane prima di entrare nello studio
6. ECOG performance status ≤2
|
|
E.4 | Principal exclusion criteria |
1. Patients who have had previous chemotherapy.
2. Patients who have had radiotherapy within 4 weeks prior to entering the study.
