Brief Summary

PROSTAC is a prospective multicentre observational study in metastatic Castration-Resistant Prostate Cancer (mCRPC), designed to explore prognostic biomarkers in patients undergoing treatment with docetaxel or cabazitaxel

Conditions

Advanced Prostate Cancer; Cabazitaxel; Docetaxel

Keywords

metastatic Castration Resistant Prostate Cancer; Taxanes; Biomarkers

Outcome Measures

Primary Outcomes (1)

• To validate the prognostic value of the gene-expression signature from peripheral blood described by Olmos et al (Lancet Oncol 2012) on overall survival of mCRPC patients

  48 months

Secondary Outcomes (7)

• To analyze the prognostic value of the gene-expression signature described by Olmos et al on biochemical and radiological progression-free survival

  48 months

• To analyze the prognostic value of early changes in the gene-expression signature described by Olmos et al

  48 months

• 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)

  48 months

• To validate the prognostic value of classical nomograms designed to assess the outcomes of mCRPC patients in these both cohorts of patients

  48 months

• To analyze the prognostic value of TMPRSS2-ERG rearrengement and PTEN loss in these cohorts

  48 months

Study Arms (2)

Docetaxel

Docetaxel 75mg/m2 IV every 3 weeks

Cabazitaxel

Cabazitaxel 20-25mg/m2 IV every 3 weeks

Eligibility Criteria

• Age: 18 Years - 99 Years
• Sex: male
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Castration-Resistant Prostate Cancer patients

You may qualify if:

• Male age ≥ 18 years
• Histologically confirmed adenocarcinome of the prostate
• ECOG Performance Status ≤ 2
• Castration resistance must be documented with surgical or medical castration with serum testosterone \< 50 ng/mL (\< 2.0 nM).
• Men diagnosed with at least one metastatic lesion on CT or bone scan.
• Documented biochemical and/or radiographic progression to previous treatment according to PCWG2 criteria.
• Patients who are candidates for standard of care treatment with docetaxel 75mg/m2 every 3 weeks or cabazitaxel 20-25mg/m2 every 3 weeks intravenously.
• Availability of formalin-fixed paraffin-embedded blocks from the prostate biopsy and/or radical prostatectomy.
• Acceptable hematological, hepatic and renal functions.

You may not qualify if:

• 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.
• 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
