About this study

Official title: Randomized Trial of Concomitant Hypofractionated IMRT Boost Versus Conventional Fractionated IMRT Boost for Localized High Risk Prostate Cancer

Randomized trial comparing 2 external beam radiotherapy fractionation schemes in patients with localized high risk prostate cancer. Primary endpoint is acute toxicity.

Read the detailed description

Patients enrolled onto this study will be randomized to one of the following treatment arms:

  • Standard fractionation: Using 2 sequential IMRT plans, the pelvic lymph nodes and prostate will initially be treated to 46 Gy in 23 fractions, followed by a subsequent boost to the prostate to a total dose of 78 Gy.
  • Hypofractionation: Using a one phase IMRT plan, the pelvic lymph nodes will be treated to a dose of 48 Gy in 25 fractions, while the prostate will be treated to a dose of 68 Gy in 25 fractions concomitantly (simulataneous integrated boost).

In addition, all patients receive 1.5- 3 years of androgen deprivation therapy.

What is being measured

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

  1. Acute Toxicity

    Proportion of patients experiencing grade >=2 acute toxicity

    Measured: within 3 months after starting radiotherapy

Secondary outcomes (3)
  1. Late Toxicity

    Proportion of patients experiencing grade >= 2 late toxicity

    Measured: beyond 3 months of starting radiotherapy

  2. Biochemical Control (Phoenix Definition)

    Actuarial measure of patients failing biochemically (defined as PSA nadir + 2 ng/mL)

    Measured: at 5 years

  3. Overall Survival

    Actuarial measure of patients being alive

    Measured: at 5 years

Questions about this trial

What is this clinical trial studying?

A study testing Conventionally Fractionated versus Hypofractionated Boost in people with Prostate Cancer, run by Dr. Patrick Cheung at 1 site in Canada.

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 5 inclusion and 6 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 8 Mar 2022. 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 Canada. 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?

Acute Toxicity (time frame: within 3 months after starting radiotherapy). 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 8 Mar 2022.
