A Study of Alpharadin® With Docetaxel in Patients With Bone Metastasis From Castration-Resistant Prostate Cancer (CRPC) - Full Text View

Purpose

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.

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 ]

Estimated Enrollment:	60
Study Start Date:	July 2010
Estimated Study Completion Date:	October 2014
Estimated Primary Completion Date:	October 2014 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Alpharadin® + docetaxel	Drug: Alpharadin® (Radium-223 dichloride) + 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	Drug: Docetaxel 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.

Assigned Interventions

Experimental: Alpharadin® + docetaxel

Drug: Alpharadin® (Radium-223 dichloride) + 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

Drug: Docetaxel

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.

Detailed Description:

Within the U.S:, the trial is conducted under an IND sponsored by Bayer.
