What is being measured

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

  1. Immunohistochemistry of tumor cell proteins will be performed on prostate biopsies to detect for androgen receptors and other protein products related to oncogenes or tumor suppressor genes thought to play a role in radiation or ADT.

    Measured: 2 years follow up

Secondary outcomes (2)
  1. DNA sequencing will be performed on prostate tumor DNA to determine the mutational status of several oncogenes and tumor suppressor genes including genes coding androgen receptors.

    Measured: 2 years follow up

  2. RNA sequencing will be performed on several oncogenes and tumor suppressor genes including genes coding androgen receptors to detect RNA expression including genes related to the androgen receptor.

    Measured: 2 years follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by University of Florida at 1 site in United States.

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 2 inclusion and 0 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The record says: withdrawn, as of the sponsor's last update on 16 Nov 2018. 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 United States. 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The study was withdrawn before enrolling participants, so there are no results.

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?

Immunohistochemistry of tumor cell proteins will be performed on prostate biopsies to detect for androgen receptors and other protein products related to oncogenes or tumor suppressor genes thought to play a role in radiation or ADT. (time frame: 2 years follow up). 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 NCT03296124, which also lists 17 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 16 Nov 2018; AzTrials last refreshed its copy on 1 Nov 2026.
