Inclusion Criteria

I-1) Men aged = 18 years
I-2) Histologically confirmed prostate cancer
I-3) Presence of metastatic bone disease according to at least one of the following modalities: bone scan (scintigraphy, PET-CT), confirmed pathological fracture, evidence of bone metastases confirmed by MRI or CT
I-4) Presence of progression defined as at least one of the following:
I-4a) PSA level increasing by at least 2 ng/mL at an interval of at least 14 days with an absolute value = 5 ng/mL and = 50% above the PSA minimum reached during the ADT (androgen deprivation therapy) or above the level prior to treatment, if there was no response.
I-4b) Two or more new lesions discovered on the bone scan or CT or MRI as compared with the preceding scan
I-5) Continuing castrate condition: Patients who did not undergo surgical orchiectomy have to continue hormone drug therapy (GnRH/LHRH analogs) to maintain the castrate level of serum testosterone = 1.7 nmol/l (50 ng/dl). The castrate condition has to be at least 3 months before enrolment to the study and continue for the study duration.
I-6) The following laboratory values: WBC > 4 x 10(9)/L, ANC = 1.5x 10(9)/L, platelet count > 100 x 10(9)/L, Hb = 90 g/L, Hct > 30%, Creatinine under 1.5 times the upper limit of normal, bilirubin, AST and ALT under 1.5 times the upper limit of normal.
I-7) ECOG 0-2 Performance Status
I-8) Signed informed consent to participate in the study
I-9) Recovery from primary local surgery, radiotherapy or orchiectomy.
I-10) At least 8 weeks from radioisotope therapy (Samarium-153, Strontium -89 or similar)

Primary Outcome Measures
NameTimeMethod
Main Objective: The clinical trial’s objective is to estimate the survival rate of patients 34 months after randomization, estimate the proportion of patients without progression 34 months after randomization, evaluate quality of life and the influence on the pain scale scoring using the standardized EORTC QLQ-C30 (version 3.0) questionnaire and the incidence of adverse events.<br><br>An exploratory objective is to search for potential biomarkers that could play a role as prognostic factors, indicate the biological effect of ACI on the immune-reponse or identify a subgroup of patients profiting from cancer immunotherapy based on gene expression profiling.<br>;Secondary Objective: not applicable;Primary end point(s): • The survival rate of patients 34 months after randomization. ;Timepoint(s) of evaluation of this end point: N/A
