About this study

Official title: Prospective Multi-Centre Study of Prognostic Factors in Metastatic Castration-Resistant Prostate Cancer Patients Treated With Abiraterone Acetate.

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

Read the 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.

Abiraterone AcetateAbiraterone Acetate 1000 mg/24h plus Prednisone 5mg/12h

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    Measured: Initially 48 months, currently 60 months

Secondary outcomes (7)
  1. To analyze the prognostic value of the gene-expression signature described by Olmos et al on biochemical and radiological progression-free survival

    Measured: Initially 48 months, currently 60 months

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

    Measured: Initially 48 months, currently 60 months

  3. 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)

    Measured: Initially 48 months, currently 60 months

  4. To validate the prognostic value of classical nomograms designed to assess the outcomes of mCRPC patients in these patients

    Measured: Initially 48 months, currently 60 months

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

    Measured: Initially 48 months, currently 60 months

  6. 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

    Measured: Initially 48 months, currently 60 months

  7. To correlate the presence of somatic and/or germinal mutations with the outcomes of these patients

    Measured: Initially 48 months, currently 60 months

Questions about this trial

What is this clinical trial studying?

An observational study of Advanced Prostate Cancer and Abiraterone ACetate, run by Centro Nacional de Investigaciones Oncologicas CARLOS III at 24 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome 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 (time frame: Initially 48 months, currently 60 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2020.
