Has started treatment with bisphosphonates less than 3 months prior to administration of study drug. Patients are allowed to be on bisphosphonates provided patient is on a stable dose for > 12 weeks before administration of study drug. 8. Patients who are <= 4 weeks (6 weeks for bicalutamide) post withdrawal of antiandrogen therapy 9. Patients who have started on systemic steroids, within a week prior to study drug administration or who have stopped steroids within a week prior to study drug administration 10.

Visceral metastases from prostate cancer as assessed by abdominal/pelvic CT or MRI within six weeks before administration of study drug; Lung lesions from prostate cancer as assessed by Chest Xray within 6 weeks. This requirement does not include abdominal or pelvic lymph node involvement (individual lymph node size must not exceed 1 cm in short diameter) which is acceptable. 12. Bulky loco-regional disease 13. Other serious illness or medical condition.

| Measure | Time frame |
|---|---|
| Main Objective: To compare the proportion of patients with PSA response (PSA decrease of 50% from baseline, confirmed three weeks later) of three different repeat dose regimens of Alpharadin in patients with hormone refractory prostate cancer and skeletal metastases, in order to select a dose for the Phase III programme. ; Secondary Objective: i) To compare the maximum percent decrease of PSA from baseline of three different repeat dose regimens of Alpharadin in order to select a dose for the Phase III programme. ii) To compare the effect on bone specific alkaline phosphatase (B-ALP) of three doses regimens of Alpharadin. iii) To examine for correlation between B-ALP and PSA. iv) To determine the effect of three different repeat dose regimens of Alpharadin on time to skeletal related events. v) To determine the effects of these three repeat dose regimens of Alpharadin on pain response, in patients with pain. vi) To determine the safety, tolerability and long-term toxicity of these three repeat dose regimens. vii) Time to death ;Primary end point(s): Prostate Specific Antigen (PSA) response; each patient will be classified as PSA responder/non-responder according to the definition of PSA response | — |
