The purpose of the study is to investigate the safety, biodistribution, radiation dosimetry and pharmacokinetics of three intravenous escalating dose levels of Alpharadin.
Drug: Radium-223 chloride (Alpharadin™ )
Endpoint Classification: Pharmacokinetics/Dynamics Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
||Phase 1, Open-label, Single Ascending-dose Study to Assess Safety, Pharmacokinetics, Biodistribution and Radiation Dosimetry of Intravenous Doses of Alpharadin™ Injection (Radium-223 Chloride) in Patients With HRPC and Skeletal Metastases
Primary Outcome Measures:
- All safety data, including adverse events, occurrence of treatment-emergent adverse events, changes in laboratory variables, vital signs, ECG, physical examination, long term radiation toxicity, including results of bone marrow biopsy [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
- Biodistribution, dosimetry and pharmacokinetics (whole body activity assessment, the counts in region-of-interest (ROIs) from anterior and posterior whole-body images, and the assay of activity in blood [ Time Frame: 6 days after injection ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Post-treatment PSA effect: PSA decline, time to PSA progression after PSA response [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Post-treatment bone markers effect: Changes in bone marker values from pre- to post administration [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Circulating tumor cells (CTCs) enumeration and role of molecular profiling of CTC in predicting sensitivity to treatment and treatment response. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

The patients will receive Alpharadin as an escalating dose of either 50, 100 or 200 kBq/kg b.w. (0.0014, 0.0027 or 0.0054 mCi/kg).
Drug: Radium-223 chloride (Alpharadin™ )
Single dose, doses of 50 kBq/kg, 100 kBq/kg, or 200 kBq/kg body weight (0.0014, 0.0027 or 0.0054 mCi/kg)
Within the U.S., the trial is conducted under an IND sponsored by Bayer.

- Have histologically or cytologically evidence of adenocarcinoma of the prostate.
Have progressive castrate metastatic disease as shown by at least one of the following:
Radionuclide Bone Scan: New osseous lesions. MRI or CT: At least a 20% increase in the sum of the LD of target lesions. or

- AST and ALT ≤2,5 times upper institutional limit of the normal range
- Serum creatinine ≤2.0 mg/dl
- Must be able and willing to sign an informed consent indicating that he is aware of the investigational nature of this study in keeping with the policies of the institution and have provided written authorization for use and disclosure of protected health information.
- Must be willing and able to comply with the protocol, and agrees to return to the hospital for follow-up visits and examination.
- Have received an investigational drug within 4 weeks prior to the administration of Alpharadin, or is scheduled to receive one during the treatment and post-treatment period.
- Have received chemo-, immunotherapy, or external radiotherapy within the last 4 weeks prior to administration of study drug, or has not recovered from acute adverse events as a result of such therapy.
- Have received prior hemibody external radiotherapy*.
- Have a need for immediate external radiotherapy.
- Have 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, have changed the dose within 4 weeks before administration of study drug.
- Have started or stopped systemic steroids within a week prior to study drug administration, or are expected to be subject to changes in the systemic steroid medication
- Have imminent or established spinal cord compression based on clinical findings and/or MRI.

Any other serious illness or medical condition, for example:
- any uncontrolled infection
- any patient who has clinical heart failure severe enough to cause marked limitation of activity, and who is only comfortable at rest; or any patient who has heart failure more severe than this (NYHA Heart Failure Class III or IV)
