About this study

Official title: Development of Tissue Predictors of Abiraterone Benefit in Men With mCRPC

This is an observational, prospective (study following participants forward in time), multi-center (study conducted in more than 1 center) study to identify the predictive factors that will effectively predict the response to abiraterone treatment in metastatic castration-resistant prostate cancer (mCRPC). The entire duration of study will be approximately 3 year. Participants will primarily be evaluated for achieving biochemical or radiological progression after receiving abiraterone treatment based on EAU 2017 practice guideline criteria. For this, we put our attentions on the HOXB3 (an alternative factor of WNT signaling pathway), FKBP5 (FK506 Binding Protein 5, Androgen-regulated gene), NTS (neurotensin, neuroendocrine differentiation can be induced by NTS) and YAP1 (yes-associated protein 1, a biomarker for cancer stem cell), which are selected from the data of gene-array for various subtypes of CRPC (unpublished data). Response to abiraterone treatment will also be predicted using other androgen-regulated genes like AKR1C3 and PCNA.

Read the detailed description

It is now accepted that castration-resistant prostate cancer (CRPC) is not really androgen-independent and continues to rely on androgen signaling. Abiraterone is an inhibitor of cytochrome P450 17A1 (CYP17A1) that impairs androgen-receptor signaling by depleting adrenal and intratumoral androgens. After studies showed improved survival with abiraterone, it was approved by the Food and Drug Administration for the treatment of metastatic castration-resistant prostate cancer (mCRPC).

mCRPC is a syndrome other than a disease. The mechanisms of mCRPC contain aberrant activation of androgen signaling, abnormal transition between epithelial and mesenchymal and induction of neuroendocrine differentiation (NED). In addition, cellular heterogeneity represents an omnipresent feature in human tumors, which contain cells with diverse morphology, cytogenetic markers, growth kinetics, immunological characteristics, metastatic ability, and sensitivity to therapeutics.

This is an observational, prospective (study following participants forward in time), multi-center (study conducted in more than 1 center) study to identify the predictive factors that will effectively predict the response to abiraterone treatment in metastatic castration-resistant prostate cancer (mCRPC). The entire duration of study will be approximately 3 year. Participants will primarily be evaluated for achieving biochemical or radiological progression after receiving abiraterone treatment based on EAU 2017 practice guideline criteria. For this, we put our attentions on the FKBP5 (FK506 Binding Protein 5, Androgen-regulated gene), NTS (neurotensin, neuroendocrine differentiation can be induced by NTS) and YAP1 (yes-associated protein 1, a biomarker for cancer stem cell), which are selected from the data of gene-array for various subtypes of CRPC. Response to abiraterone treatment will also be predicted using other androgen-regulated genes like AKR1C3 and PCNA.

What is being measured

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

  1. PSA response rates

    PSA response rates between FKBP5(protein)-positive and FKBP5(protein)-negative (including YAP1-positive and NTS-positive) patients; PSA response rates between patients with higher or lower expression of androgen-regulated genes (AKR1C3, FKB5, PCNA).

    Measured: 2 YEARS

Secondary outcomes (3)

  1. PSA progression-free survival (pPFS)

    pPFS between FKBP5-positive and FKBP5-negative (including YAP1-positive and NTS-positive) patients; pPFS between patients with higher or lower expression of androgen-regulated genes (AKR1C3, FKB5, PCNA).

    Measured: 3 YEARS

  2. clinical or radiographic progression-free survival (cPFS)

    cPFS between FKBP5-positive and FKBP5-negative (including YAP1-positive and NTS-positive) patients; cPFS between patients with higher or lower expression of androgen-regulated genes (AKR1C3, FKB5, PCNA).

    Measured: 3 YEARS

  3. overall survival (OS)

    OS between FKBP5-positive and FKBP5-negative (including YAP1-positive and NTS-positive) patients; OS between patients with higher or lower expression of androgen-regulated genes (AKR1C3, FKB5, PCNA).

    Measured: 3 YEARS

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 4 inclusion and 3 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: finished, as of the sponsor's last update on 14 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

PSA response rates (time frame: 2 YEARS). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03176381, which also lists 13 linked publications.

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 14 Nov 2023.
