The main purpose of this study is to establish a recommended dose of Alpharadin to be used in combination with docetaxel in patients with bone metastases from castration-resistant prostate cancer and to investigate safety and explore efficacy of the recommended dose.
Castration-Resistant Prostate Cancer
Drug: Radium-223 dichloride (Xofigo, BAY88-8223) + docetaxel
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Phase I/IIa Study of Safety and Efficacy of Alpharadin® With Docetaxel in Patients With Bone Metastasis From Castration-Resistant Prostate Cancer
Primary Outcome Measures:
- Dose-escalation: Assessment of dose-limiting toxicities [ Time Frame: When 6 weeks post-injection data are available for the first combined injection of Alpharadin/docetaxel ] [ Designated as safety issue: Yes ]
- Expanded safety cohort: Safety of combining Alpharadin with docetaxel (incidence and severity of adverse events and serious adverse events, changes from baseline in laboratory variables, vital signs and physical examination) [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Signs of long-term radiation toxicity: incidence of manifestations of potential late toxicity, such as new primary cancers and bone marrow changes (acute myelogenous leukaemia, myelodysplastic syndrome, and aplastic anaemia) [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
- Exploratory efficacy measurements of Alpharadin in combination with docetaxel versus docetaxel alone such as changes in bone markers, PSA and CTC, time to progression and overall survival [ Time Frame: 12 months ] [ Designated as safety issue: No ]
- Exploratory patient self-reporting of pain intensity [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Experimental: Alpharadin + docetaxel
Drug: Radium-223 dichloride (Xofigo, BAY88-8223) + docetaxel
Alpharadin (Radium-223 dichloride) is administered intravenously as a bolus injection. In the randomized phase IIa part of the protocol, the dose established in the dose-escalation part of the protocol (Phase I) will be used, i.e. 5 doses of 50 kBq/kg b.w. every 6 weeks in combination with the approved step-down dose of docetaxel (60 mg/m2) administered intravenously every 3 weeks with 5 mg prednisone twice a day continuously and pre-medication with dexamethasone.
Active Comparator: Docetaxel alone
Docetaxel (75 mg/m2) will be administered intravenously every 3 weeks with 5 mg prednisone twice a day continuously and pre-medication with dexamethasone. Step-down to 60 mg/m2 is allowed as per the approved docetaxel label.
The trial was initially conducted and submitted by Algeta ASA. After acquiring Algeta, Bayer is now the sponsor.
