Brief summary: PROSABI is a prospective multicentre observational study in metastatic Castration-Resistant Prostate Cancer (mCRPC), designed to explore prognostic biomarkers in patients undergoing treatment with abiraterone

Detailed description: This study is a prospective biomarker study of patients with mCRPC undergoing treatment with abiraterone as standard of care treatment. The participants will undergo serial pre- and post-therapy blood collection for biomarker analysis as part of the primary objective of the study.

Eligibility criteria: Inclusion Criteria:

1. Male age ≥ 18 years
2. Histologically confirmed adenocarcinome of the prostate
3. ECOG Performance Status ≤ 2
4. Castration resistance must be documented with surgical or medical castration with serum testosterone \< 50 ng/mL (\< 2.0 nM).
5. Men diagnosed with at least one metastatic lesion on CT or bone scan.
6. Documented biochemical and/or radiographic progression to previous treatment according to PCWG2 criteria.
7. Patients who are candidates for standard of care treatment with abiraterone acetate: 1000 mg every 24 hours plus prednisone 5 mg every 12 hours.
8. Availability of formalin-fixed paraffin-embedded blocks from the prostate biopsy and/or radical prostatectomy.
9. Acceptable hematological, hepatic and renal functions.9. Acceptable haematological, hepatic and renal functions.

Exclusion Criteria:

1. Previous cancer diagnosis, except those patients who had a localized malignant tumour and who are five years cancer-free or those diagnosed with skin cancers (of non-melanoma type) or excised in situ carcinomas.
2. Any condition or reason that, in the opinion of the Investigator, interferes with the ability of the patient to participate in the trial, which places the patient at undue risk, or complicates the interpretation of safety data

Primary outcomes:
measure: To validate the independent prognostic value of the gene-expression signature from peripheral blood described by Olmos et al (Lancet Oncol 2012) on overall survival of mCRPC patients
timeFrame: Initially 48 months, currently 60 months
Secondary outcomes:
measure: To analyze the prognostic value of the gene-expression signature described by Olmos et al on biochemical and radiological progression-free survival
timeFrame: Initially 48 months, currently 60 months
measure: To analyze the prognostic value of early changes in the gene-expression signature described by Olmos et al
timeFrame: Initially 48 months, currently 60 months
measure: To compare the prognostic value of the gene-expression signature described by Olmos et al versus the gene-expression signature described by Ross et al (Lancet Oncol, 2012)
timeFrame: Initially 48 months, currently 60 months
measure: To validate the prognostic value of classical nomograms designed to assess the outcomes of mCRPC patients in these patients
timeFrame: Initially 48 months, currently 60 months
measure: To analyze the prognostic value of TMPRSS2-ERG rearrengement and PTEN loss in these cohorts
timeFrame: Initially 48 months, currently 60 months
measure: To analyze the prognostic value of AR splicing variants, serum chromogranine and serum testosterone levels measured by ultrasensitive method in these both cohorts of patients
timeFrame: Initially 48 months, currently 60 months
measure: To correlate the presence of somatic and/or germinal mutations with the outcomes of these patients
timeFrame: Initially 48 months, currently 60 months
