Primary Outcome Measures:
  • Number of participants with Critical toxicities [ Time Frame: Up to day 28 ] [ Designated as safety issue: Yes ]
    Critical toxicities (using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.0) will be defined as the occurrence of one or more of the following drug-related toxicities: 1) ≥Grade 3 non-hematologic toxicity, 2) Grade 3 neutropenia with fever, 3) Grade 4 neutropenia that failed to recover to grade 2 or less after treatment with Granulocyte colony-stimulating factor (GCSF) within 2 weeks, 4) Grade 4 thrombocytopenia

  • Maximum drug concentration in blood after single dose administration (Cmax) of BAY88-8223 for blood samples [ Time Frame: up to 72 hours ] [ Designated as safety issue: No ]
  • Area under the concentration - time curve (AUC) of BAY88-8223 for blood samples [ Time Frame: up to 72 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in prostate specific antigen (PSA) [ Time Frame: baseline, up to 12 weeks ] [ Designated as safety issue: No ]

Enrollment: 16
Study Start Date: March 2012

  Eligibility

Ages Eligible for Study:   20 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male ≥ 20 years of age
  • Histologically or cytologically confirmed adenocarcinoma of the prostate
  • Presents with at least 2 bone metastases, confirmed by scintigraphic imaging within the previous 4 weeks
  • Patients who has failed initial hormonal therapy using either an orchiectomy or a Gonadotropin releasing hormone (GnRH) agonist in combination with an antiandrogen must first progress through antiandrogen withdrawal prior to being eligible. The minimum timeframe to document failure of anti-androgen withdrawal will be four weeks
  • Progressive castration resistant metastatic disease
  • Castrate level of testosterone (<50 ng/dL), treatment to maintain castrate levels of testosterone must be continued

Exclusion Criteria:

  • Has received an investigational drug in the 4 weeks before or is scheduled to receiving one during or in the 8 weeks after study drug administration.
  • Has received chemo-, immuno-, or radiotherapy within the last 4 weeks prior to entry in the study, or has not recovered from acute adverse events as a result of such therapy
  • Has received prior hemibody external radiotherapy
  • Has a need for immediate external radiotherapy
  • Has received systemic radiotherapy with radium-223, strontium-89, samarium-153, rhenium-186 or rhenium-188 for the treatment of bony metastases within the last 24 weeks prior to administration of study drug
  • When receiving bisphosphonates, has changed the dose within 4 weeks before administration of study drug
