Feasibility and Safety Study Using Preoperative High-Dose Single-Fraction Image-Guided Radiotherapy for Men Undergoing Radical Prostatectomy at High-Risk for Extraprostatic Cancer
A Phase 1 study testing High-Dose Single-Fraction Image-Guided Radiotherapy for Men Undergoing Radical Prostatectomy in people with Prostate Cancer, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.
Trial summary
This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. Read more about this study

About this study
Official title: Phase I Feasibility and Safety Study Using Preoperative High-Dose Single-Fraction Image-Guided Radiotherapy for Men Undergoing Radical Prostatectomy at High-Risk for Extraprostatic Cancer
This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. The investigators are especially interested in men who are at risk for having cancer cells that have spread outside the prostate.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High-Dose Single-Fraction Image-Guided Radiotherapy for Men Undergoing Radical ProstatectomyRadiation
A baseline DCE-MRI will be obtained prior to the day of radiotherapy treatment. Immediately following the delivery of radiotherapy another DCE-MRI will be performed to assess for perfusion changes in the prostate resulting from irradiation. RP will be completed within 6 weeks (+ 2 weeks) of radiation and the RP specimen will be assessed for radiation treatment effect and other pathologic parameters (including surgical margin status) by a dedicated genitourinary pathologist. Following RP, participants will follow-up with their surgeon every 3 months for one year, with visits alternating between the urologist and the radiation oncologist. After the first year follow-up will occur at 6 month intervals until the patient is 3 years out from surgery.

What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the feasibility and safety of single-fraction image-guided intensity modulated radiotherapy (IG-IMRT).
Given prior to radical prostatectomy (RP) in men at high risk for extraprostatic cancer.
Measured: 1 year
Secondary outcomes (3)
To analyze the changes in prostate perfusion induced by single-fraction IG-IMRT.
via dynamic contrast enhanced magnetic resonance imaging (DCE-MRI)
Measured: 1 before radiation simulation, 1 after radiation treatment
To assess the long-term toxicity of intensity modulated radiotherapy (IG-IMRT)
Given prior to radical prostatectomy (RP) with respect to urinary function, erectile function, and bowel function.
Measured: weeks 3, 6, 9, 12, 18, 24, 30, and 36 months after RP
To assess the effect of IG-IMRT on the anticipated positive margin rate at the time of RP.
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing High-Dose Single-Fraction Image-Guided Radiotherapy for Men Undergoing Radical Prostatectomy in people with Prostate Cancer, run by Memorial Sloan Kettering Cancer Center 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 8 inclusion and 8 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: withdrawn, as of the sponsor's last update on 6 Mar 2015. 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 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.
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 was withdrawn before enrolling participants, so there are no results.
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?
To assess the feasibility and safety of single-fraction image-guided intensity modulated radiotherapy (IG-IMRT). (time frame: 1 year). 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 6 Mar 2015.
