Brief Summary
Radium-223 chloride is an alpha-emitting radiopharmaceutical with proven survival benefit in patients with castration-resistant prostate cancer metastatic to bone. Beta-emitting radiopharmaceuticals have proven efficacy for palliating malignant bone pain. Nowadays, rhenium-188-HEDP is used in clinical practice for pain relief and palliative care. Several studies suggest that also rhenium-188-HEDP has the potential to improve overall survival. The purpose of this study is to investigate if treatment with rhenium-188-HEDP results in improvement of overall survival compared to treatment with radium-223-chloride.

Eligibility Criteria
You may qualify if:
- Male, 18 years or older
- Histologically confirmed prostate cancer
- Bone metastases (≥ 6 lesions) showing pathological uptake at bone scintigraphy.
- WHO performance status of ≤2
- Life expectancy of at least 6 months
- Castration-resistant disease: serum testosterone level of ≤ 1.7 nmol per liter (≤50 ng per deciliter) after bilateral orchiectomy or during maintenance treatment consisting of androgen-ablation therapy with a luteinizing hormone-releasing hormone agonist. During study treatment the maintenance androgen-deprivation therapy must be continued.
- Baseline PSA ≥5 ng/ml with evidence of progressively increasing PSA values
- Symptomatic disease with either regular use of analgesic medication or treatment with external-beam radiotherapy for cancer-related bone pain within the previous 12 weeks.
- Progression on or after treatment with docetaxel, or inability to receive docetaxel.
- Adequate renal function (serum creatinine level ≤1.5 x ULN)
- Adequate hematological function defined as absolute neutrophil count ≥ 1.5x10\^9/L and platelet count ≥100x 10\^9/L)
- Written informed consent
You may not qualify if:
- Treatment with chemotherapy within the previous 4 weeks
- Continuation of treatment with abiraterone or enzalutamide
- Previous hemibody external radiotherapy
- Systemic radiotherapy with radioisotopes within the previous 24 weeks
- Malignant lymphadenopathy ≥3cm in the short-axis diameter
- Presence of visceral metastases
- Imminent of established spinal cord compression
- Active uncontrolled bacterial, viral or fungal infection
- History of another malignancy within the last five years except adequately treated basal cell carcinoma of the skin
- Organ allografts requiring immunosuppressive therapy.
- Any serious uncontrolled concommitant disease
- Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule: those conditions should be discussed with the patient before registration in the trial.
