About this study
Official title: Phase I/II Study of Radioimmunoguided Intensity Modulated Radiotherapy (IMRT) for Prostate Cancer
The current study involves a novel and aggressive therapeutic approach for patients' prostate cancer. In addition, the investigators propose to administer hormonal therapy to patients with an especially high risk: those with initial Gleason scores of > 6, PSA > 10 ng/ml, T3/T4 primary tumors, and those found to be node positive (N+). The use of hormonal therapy in these specific settings correlates with our current standard of care. IMRT is better able to spare and protect normal tissues from receiving radiation than 3-D conformal RT. The radiotherapy would be followed by continued hormonal therapy for a total of 6 months in those who have one of the following Gleason 7 and PSA 10-20 and as per the previous version of this trial, 1 year similar to that delivered by the EORTC for higher risk patients, (those with initial Gleason scores of > 8, PSA > 20 ng/ml, or T3/T4 tumors). Those found to be N(+) would have the hormonal therapy continued indefinitely or until disease progression occurred in a manner analogous to the Messing et. al. series in prostatectomy patients. The goals are to develop and administer a program of treatment that includes the most recent developments in imaging, integrating data from both the CT scan and the ProstaScint scan to optimize prostate cancer RT. The CT scan will be used for staging and to determine the exact location of the entire prostate which will receive a reasonable dose of RT. The ProstaScint will be used to assess the spread of disease to lymph nodes as well as to determine the exact location of the tumor within the prostate gland. This region will then be boosted to a tumorcidal dose. The investigators then plan to monitor the toxicity and outcome of this treatment. The investigators expect that this program of radioimmunoguided IMRT will likely result in similar or less toxicity and increased cure rates when compared to conventional radiotherapy and standard IMRT programs.

What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcome will be assessment of toxicity as well as efficacy as determined by survival rates, freedom from biochemical relapse rates, local control rates, distant failure rates.
The main endpoint of the toxicity component is evaluating how many patients develop grade 3 or greater toxicity.
It is expected between 0 and 9% of patients will have grade 3 or 4 toxicity.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing radioimmuniguided intenstiy modulated radiotherapy in people with Prostatic Neoplasm, run by Mayo Clinic at 1 site 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 12 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 25 Feb 2011. 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 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 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?
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?
The primary outcome will be assessment of toxicity as well as efficacy as determined by survival rates, freedom from biochemical relapse rates, local control rates, distant failure rates.. 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?
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 25 Feb 2011.
