Primary Outcome Measures :
  1. radiological progression-free survival [ Time Frame: 46 months after first patient entry ]

    Radiological progression free survival (rPFS1) is defined according to the recommendations of the "Prostate-Cancer clinical trials Working Group" version 2 and referred to as the "PCWG2"; for the setting "delay/prevent" progression.

    An event of progression according to their definition is either of:

    • Objective progression of the disease according to RECIST criteria for soft tissue lesions with the additional requirement that progression at the first follow-up assessment be confirmed by a second scan ≥ 6 weeks apart
    • Appearance of ≥ 2 new bone lesions (see chapter 6 for clinical examinations required) and for the first follow-up assessment only, a confirmatory scan performed ≥ 6 weeks later that shows a minimum of two or more additional new lesions

Secondary Outcome Measures :
  1. Overall survival [ Time Frame: 63 months after first patient entry ]
    number of participants

  2. prostate cancer specific survival [ Time Frame: 63 months after first patient entry ]
    number of participants

  3. First symptomatic skeletal event [ Time Frame: 46 and 63 months after first patient entry ]
    number of participants

  4. Time and incidence of first skeletal progression-free [ Time Frame: 46 and 63 months after first patient entry ]
    number of participants

  5. Time from entry to initiation of next systemic therapy [ Time Frame: 46 and 63 months after first patient entry ]
    number of participants

  6. Treatments elected after first disease progression [ Time Frame: 46 and 63 months after first patient entry ]
    number of participants

  7. Second progression-free survival in sequential regimen [ Time Frame: 46 and 63 months after first patient entry ]
    number of participants

  8. Pain [ Time Frame: 46 and 63 months after first patient entry ]
    Brief Pain Inventory questionnaire

  9. Time to pain progression [ Time Frame: 63 months after first patient entry ]
    number of participants

  10. Occurence of adverse events [ Time Frame: 63 months after first patient entry ]
    Adverse events will be graded according to the "Common Terminology Criteria for Adverse events" CTCAE, version 4.0

  11. Time to use of opioid analgesics [ Time Frame: 63 months after first patient entry ]
    number of participants

  12. Quality of Life [ Time Frame: 46 and 63 months after first patient entry ]
    EQ5D-5L questionnaire

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically confirmed diagnosis of prostate adenocarcinoma:

    1. Asymptomatic or mildly symptomatic (defined as no opioids and Brief Pain Inventory score)
    2. Metastatic to bone with ≥ 2 bone metastases (area of increase uptake on 99mTC BS (Technetium-99m bone scintigraphy) confirmed by standard X-Ray, Computed tomography (CT), or Magnetic resonance imaging (MRI)) with or without additional lymph node metastases. Visceral metastases are not allowed
    3. Progressive Castration-resistant prostate cancer (CRPC) according to Prostate Cancer Working Group 2 (PCWG2) i.e. either of:
  • For patients who manifest disease progression solely as a rising Prostate-specific antigen (PSA) level. PCWG2 criteria require documentation of a sequence of rising PSA values at a minimum of 1-week intervals with the last value ≥ 2 ng/ml.
  • For patients with disease progression manifest in the bone, irrespective of progression by rising PSA, PCWG2 guidelines require appearance of 2 or more new lesions. Ambiguous results should be confirmed by other imaging modalities than bone scan and x-ray (e.g.: CT-scan or MRI).
  • For patients with disease progression manifest at nodal sites, irrespective of progression by rising PSA, PCWG2 requires progression according to RECIST 1.1.
  • Ongoing androgen deprivation therapy with LHRH (Human luteinizing hormone-releasing hormone) agonist or antagonist or bilateral orchiectomy
  • Patients must be at least 18 years old
  • WHO Performance status 0-1
  • Charlson score ≤ 3
  • Castrate serum levels of testosterone (< 50 ng/dL)

    1. Adequate bone marrow function (absolute neutrophil count 1.5109/L; platelets 100 109/L, and hemoglobin > or = 10.0 g/dl.).
    2. Total bilirubin level ≤ 1.5 x institutional upper limit of normal (ULN), except for patient with Gilbert's disease 5.0 ULN
    3. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < or = 2.5 x ULN
