Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • informed consent obtained
  • men > 18 years
  • histologically confirmed prostate adenocarcinoma (centrally reviewed)
  • high risk prostate cancer, defined as at least one of: clinical stage T3, or gleason score 8-10, or PSA > 20ng/mL

Who cannot join

  • prior pelvic radiotherapy
  • anticoagulation medication (if unsafe to discontinue for gold seed insertion)
  • diagnosis of bleeding diathesis
  • pelvic girth > 40cm (to ensure visibility of gold seeds on electronic portal imaging)

About this study

Official title: Phase II Study of Dose-escalated, Hypofractionated Radiotherapy and Androgen Deprivation Therapy for High-Risk Prostate Cancer

The purpose of this study is to determine the safety and efficacy of a short course of radiotherapy (40Gy/5 fractions/29 days) for the treatment of high risk prostate cancer currently being managed with primary androgen deprivation therapy (PADT).

Read the detailed description

Primary Endpoints:

  • Acute gastrointestinal (GI) and genitourinary (GU) Common Terminology Criteria for Adverse Events (CTCAE) v3.0 toxicities

Secondary Endpoints:

  • Late GI and GU Radiation Therapy Oncology Group (RTOG) toxicities
  • Biochemical disease-free survival
  • Biopsy positive rate at 3 years
  • Quality of life using the Expanded Prostate Cancer Index Composite (EPIC) questionnaire
  • Develop a biobank of DNA and serum extracted from blood and urine to analyze and develop new biomarkers for prostate cancer progression or susceptibility to severe toxicity

What is being measured

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

  1. Incidence of grade 3+ rectal toxicity

    Common Terminology Criteria for Adverse Events (CTCAE) v3.0

    Measured: Acute period (up to 3 months)

Secondary outcomes (4)
  1. Incidence of grade 3+ urinary toxicity

    Common Terminology Criteria for Adverse Events (CTCAE) v3.0

    Measured: Acute (up to 3 months) and Late (after 6 months of follow-up)

  2. Quality of Life

    Expanded Prostate Cancer Index Composite (EPIC)

    Measured: 5 years

  3. Biochemical (ie.prostate specific antigen) disease free survival

    Measured: 5 years

  4. Incidence of grade 3+ rectal toxicity

    Common Terminology Criteria for Adverse Events (CTCAE) v3.0

    Measured: Late (after 6 months of follow-up)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Hypofractionated radiation in people with Prostate Cancer, run by Sunnybrook Health Sciences Centre 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 4 inclusion and 7 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 24 Nov 2020. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

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

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?

Incidence of grade 3+ rectal toxicity (time frame: Acute period (up to 3 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 24 Nov 2020.
