About this study

Official title: A Randomized Trial of a Shorter Radiation Fractionation Schedule for the Treatment of Localized Prostate Cancer

To improve the management of patients with early stage prostate cancer.

Read the detailed description

To compare the efficacy of a shorter radiation fractionation schedule to the prostate (5250 cGy/20 fractions over 28 days) with a conventional schedule (6600 cGy/33 fractions over 45 days) in men receiving radiotherapy for Stage T1a moderately or poorly differentiated, or T1b, T1c, or T2 prostate cancer. The primary outcome is local control in the prostate and secondary outcomes include toxicity, disease free survival, survival, quality of life and economics.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 5250 cGy/20 fractions over 28 days and 6600 cGy/33 fractions over 45 days in people with Prostate Cancer, run by Ontario Clinical Oncology Group (OCOG) at 16 sites 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 2 inclusion and 11 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 17 Aug 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites 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 phase mean?

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

time to PSA failure (time frame: 10 years). 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 NCT00201916, which also lists 1 linked publication.

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 17 Aug 2010.
