About this study

Official title: PROVENT: A Randomised, Double Blind, Placebo Controlled Feasibility Study to Examine the Clinical Effectiveness of Aspirin and/or Vitamin D3 to Prevent Disease Progression in Men on Active Surveillance for Prostate Cancer

To demonstrate the acceptability and feasibility of recruitment to a randomised chemoprevention study of standard (300mg) or low dose (100mg) aspirin vs. placebo and/or Vitamin D3 vs. placebo in patients enrolled on an Active Surveillance programme for prostate cancer.

Read the detailed description

The PROVENT study is a randomised, double blind, placebo controlled feasibility study to examine the clinical effectiveness of aspirin and/or Vitamin D3 to prevent disease progression in men on Active Surveillance for prostate cancer

The main outcome measure of the trial is the rate of patient recruitment to a randomised chemoprevention study in men enrolled on an Active Surveillance programme for prostate cancer

Secondary outcomes include the response to treatment as determined by serial multi-parametric magnetic resonance imaging (MRI) of the prostate, biochemical disease progression and histological disease progression after 12 months of therapy and finally toxicity and/or allergy to both aspirin and Vitamin D3.

What is being measured

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

  1. Rate of Patient Recruitment to a Randomised Chemoprevention Study in Men Enrolled on an Active Surveillance Programme for Prostate Cancer. Number Accrued Per Month.

    The proportion of eligible patients that join the trial over the 12-month trial recruitment period.

    Measured: 12 months

Secondary outcomes (4)
  1. Response to Treatment as Determined by Serial Multi-parametric Magnetic Resonance Imaging (MRI) of the Prostate. New Lesion Present or Existing Lesion + or - in Size.

    Radiological progression was defined as 'development of a Prostate Imaging-Reporting and Data System (PI-RADS) 4/5 lesion (17) on mpMRI, where no lesion was identified before, 33% volume increase in the size of the lesion, or radiological upstaging to T3 or above based on local site reports.' Absence of these features represented radiologically stable disease.

    Lesion on multi-parametric imaging where no MRI lesion at screening. An MRI scan shows a screening + or - in volume by > 33%, or an upgrading of MRI stage of disease to ≥3.

    Measured: 3 years

  2. Number of Participants With Biochemical (PSA) Disease Progression

    50% increase in serum Prostate Specific Antigen at 12 months from baseline.

    Measured: 12 months

  3. Number of Participants With Histological Disease Progression

    Histological disease progression will be defined as an increase in Gleason scores from: Gleason 3+3 to Gleason score 7 or higher Gleason 3+4 (score 7) to 4+3 (score 7) or Gleason 4+3 to a higher score

    Or a 50% increase in maximum cancer core length (MCCL)

    Measured: 3 years

  4. Number of Patients With Adverse With Toxicity, Allergy or Symptoms From Aspirin or Vitamin D

    Aspirin toxicity: Haemorrhagic stroke, anaphylaxis following administration, gastrointestinal bleeding requiring intervention (both medical and surgical)

    Vitamin D3 toxicity: Hypercalcaemia, Anaphylaxis

    Measured: 18 months + 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing High dose Aspirin & Vitamin D and Low dose Aspirin , Vitamin D in people with Prostate Cancer, run by Queen Mary University of London at 7 sites in United Kingdom.

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 0 inclusion and 20 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 29 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Mar 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Rate of Patient Recruitment to a Randomised Chemoprevention Study in Men Enrolled on an Active Surveillance Programme for Prostate Cancer. Number Accrued Per Month. (time frame: 12 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 29 Mar 2023.
