18F-DCFPyL Imaging as a Method to Assess Treatment Response to Stereotactic Body Radiation Therapy
United States130 participantsStarted 2022-08-31
Plain-language summary
Background:
Identifying medium- and high-risk prostate cancer early may allow for treatments to work. But identification can be hard. Researchers want to see if a radiotracer used during PET scans can help.
Objective:
To test how an imaging agent called 18F-DCFPyL detects response to standard prostate cancer treatment.
Eligibility:
People ages 18 and older with newly diagnosed prostate cancer who have no evidence of distant metastatic disease and plan to get stereotactic body radiation therapy (SBRT) with or without androgen deprivation therapy (ADT).
Design:
Participants will be screened with:
Medical history
Physical exam
Blood tests
MRI
Participants will have baseline MRI and PET/CT scans. For the MRI, they may get a contrast agent by IV injection. For the PET/CT scan, they will get an IV injection of 18FDCFPyL. About 1 to 2 hours later, they will get the PET/CT scan. During the scans, participants will lie on their back and remain still for 45 minutes to 1 hour. These scans will be repeated at different points during the study.
Participants will get SBRT with or without ADT.
Participants will complete questionnaires about their quality of life.
Participants will be asked about any symptoms they are having. They will also be asked about medications they are using. They may have a physical exam.
Participants will give blood and urine samples. They will give a tumor sample from a biopsy they have had in the past.
After treatment, participants will have follow-up visits. These will occur 1 month after treatment, then every 3 months for a year, and then every 6 months for 1 more year.

* INCLUSION CRITERIA:
* Biopsy proven localized prostate cancer in whom stereotactic body radiation treatment (SBRT) with or without neoadjuvant androgen deprivation therapy (ADT) is planned for definitive management (NIH laboratory of pathology confirmation is not required).
* Must have at least 1 MRI detected, biopsy proven localized prostate cancer.
* Age \>= 18 years
* ECOG performance status \<= 2
* For individuals with evidence of human immunodeficiency virus (HIV) infection, individuals must be on effective anti-retroviral therapy with undetectable viral load within the prior 6 months are eligible.
* For individuals with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
* For individuals with a history of hepatitis C virus (HCV), the infection must have been treated and cured. For individuals with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
* Ability of subject to understand and the willingness to sign a written informed consent document.
* Men must agree to use adequate contraception with their partner (hormonal or barrier method of birth control; abstinence) for the duration of study participation and 2 months after the last 18F-DCFPyL scan.
EXCLUSION CRITERIA:
* Receiving prior androgen deprivation therapy, radiotherapy, or surgery for prostate cancer.
* Any condition that is likely to interfere with study procedures o…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
