About this study

Official title: Low Dose Supplemental External Radiation With PD-103 Versus PD-103 Alone For Prostate Cancer

The primary purpose of this study is to evaluate two treatment regimens for prostate cancer, prostate implant with 20 Gy of external beam radiation therapy versus prostate implant with 0 Gy of external beam radiation therapy. Patients diagnosed with intermediate risk prostate cancer between the ages of 40 and 80 who have chosen brachytherapy with or without external beam radiation therapy as their intended treatment will be eligible and will be offered participation.

Read the detailed description

Approximately 250,000 men are currently diagnosed with prostatic cancer in the United States each year. Of those, 70% have stage T1 or T2 disease (apparently limited to the prostate gland). Clinically localized prostate cancer is a spectrum of disease, ranging from good prognosis to poor prognosis. Patients with a PSA above 10 ng/ml or Gleason score of 7 to 10 are referred to as intermediate risk, with approximately an 80% chance of cure.

Implantation of radioactive sources directly into the prostate (brachytherapy) delivers a high, localized radiation dose while sparing most the of the bladder and rectum. Brachytherapy is well established for other tumor sites, and has become a standard treatment for prostate cancer.

Establishing that a good quality implant alone is as effective as implant plus beam radiation will allow us to routinely drop the use of beam radiation, a change in policy that will decrease the risk of some complications, will be more convenient for patients, and will lower treatment costs.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing External beam radiation and Pd-103 in people with Prostate Cancer, run by Schiffler Cancer Center at 2 sites in United States.

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 1 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 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Serial PSA : 6, 12, 18 and 24 months and then yearly. (time frame: 6, 12, 18 and 24 months and then yearly). The study lists 3 primary outcomes in all. 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 NCT00241384, which also lists 10 linked publications.

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 Nov 2015; AzTrials last refreshed its copy on 2 Nov 2026.
