Trial summary

Recent studies support the use of Stereotactic Body Radiation Therapy (SBRT) for the treatment of localized prostate cancer (PrCa). SBRT is a way to deliver radiation very precisely allowing higher doses to be delivered with fewer treatments, potentially improving patient outcomes. Read more about this study

About this study

Official title: Randomized Feasibility Study of Stereotactic Body Radiotherapy (SBRT) for Localized Prostate Cancer: Cyberknife vs. Volume Modulated Arc Therapy

Recent studies support the use of Stereotactic Body Radiation Therapy (SBRT) for the treatment of localized prostate cancer (PrCa). SBRT is a way to deliver radiation very precisely allowing higher doses to be delivered with fewer treatments, potentially improving patient outcomes. Cyberknife and Volume Modulated Arc Therapy (VMAT) are accepted SBRT techniques. However, the effects of the specific SBRT treatment technique on patient outcomes have not been evaluated in randomized trials.

Although such a trial would be of great interest, patients' willingness to participate is unclear. Multiple patient and clinician factors contribute to the decision to enter a randomized trial. This feasibility study will evaluate patients' willingness to participate in a trial comparing Cyberknife and VMAT SBRT for the treatment of early stage PrCa. Patients accepting enrolment will be randomized to one of the two types of SBRT delivery. Up to 66 patients will be approached, and up to 40 randomized. A questionnaire will help to identify the factors influencing the patient's decision to participate or not. This study will gather information on feasibility, PSA control, patient outcomes and side effects, and will inform the design of a future randomized phase II/III study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Stereotactic Body Radiotherapy in people with Prostatic Neoplasms, run by Juravinski Cancer Center.

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 10 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 26 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Contact Joanna Laba, MD (905-387-9495 ext. 64702, labaj@hhsc.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient acceptability of a randomized trial comparing Cyberknife and Volume Modulated Arc Therapy (VMAT) based SBRT techniques for the treatment of localized prostate cancer as measured by number of patients willing to participate in randomized trial. (time frame: 15 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 26 Jan 2015.
