About this study

Official title: A Study of Changes in the Prostate Following Androgen Deprivation to Investigate Therapy Response and Resistance in Clinical Prostate Cancer

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.

PURPOSE: This research study is looking at blood and tissue samples from patients with prostate cancer receiving androgen deprivation therapy.

Read the detailed description

OBJECTIVES:

  • To identify the molecular and pathophysiological changes which occur during the early stages of androgen deprivation (AD) and during emerging castration-resistant prostate cancer.
  • To test functional imaging as a non-invasive tool to measure treatment response and validate this using biological endpoints.
  • To develop clinical models to predict how tumors will respond to AD and identify new targets once AD fails.

OUTLINE:

  • Group A: Patients likely to receive androgen deprivation (AD) as first-line therapy undergo blood and prostate biopsy sample collection before and after treatment on days 0 and 14 or 90. Patients receive an androgen receptor inhibitor followed by maintenance with a gonadotropin-releasing hormone analogue beginning on day 0. Patients also undergo diffusion-weighted MRI, MR spectroscopic imagining, quantitative T1W mapping, and T1W perfusion sequence.
  • Group B: Patients already receiving AD undergo blood and prostate biopsy sample collection within 4 weeks of diagnosis of castration-resistant prostate cancer and before initiating any second-line therapy.

Blood and tissue samples are assessed via DNA and RNA genetic analysis, gene expression studies, and comparative genomic hybridization to identify novel markers of androgen response and resistance.

Questions about this trial

What is this clinical trial studying?

A study testing antiandrogen therapy, releasing hormone agonist therapy and DNA analysis in people with Prostate Cancer, run by Cancer Research UK at 1 site in United Kingdom.

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

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 10 Jan 2014. 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 Kingdom. 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification of molecular and pathophysiological changes. The study lists 3 primary outcomes in all. 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 10 Jan 2014.
