An Investigational Scan (rh PSMA 7.3 PET/MRI) for the Detection of Recurrent Disease and Aid in Radiotherapy Planning in Biochemically Recurrent Prostate Cancer
United States29 participantsStarted 2021-08-04
Plain-language summary
This prospective pilot study will assess the feasibility of rh PSMA 7.3 positron emission tomography/magnetic resonance imaging (PET/MRI) scans in detecting prostate cancer that may have come back (recurrent) in patients with increasing levels of prostate-specific antigen (PSA) following prostate surgery (biochemically recurrent). An increase in PSA levels alone does not tell the doctor where the cancer may be or how much cancer there may be. Imaging tests, like a bone scan, MRI, and/or computed tomography, are often performed to help the doctor learn where or how much cancer there is, and how best to treat the cancer. rhPSMA-7.3 is a radioactive tracer agent that when used with PET/MRI imaging may help diagnose and look for the spread of prostate cancer. Prostate-specific membrane antigen (PSMA) is a protein that is expressed in prostate cancer and this agent targets the PSMA molecule. Giving rh PSMA 7.3 during PET/MRI may help doctors better find where the cancer may be spreading and how much of it there is. The results of this trial may also guide in radiotherapy planning.

Inclusion Criteria:
* Patient is male and aged \> 18 years old
* History of localized adenocarcinoma of the prostate status post (s/p) radical prostatectomy
* An initial elevated PSA \>= 0.2 followed by a subsequent confirmatory PSA \>= 0.2 clinically suspicious for biochemically recurrent disease
* If the patients were previously taking androgen deprivation therapy (ADT), it should be discontinued at least 12 weeks prior to the study
* Treatment plan includes salvage radiation with or without hormones.
* Patient willing to provide signed informed consent and willing to comply with all required study schedule events, where safe and feasible
* Non-English speaking patients may be enrolled.
Exclusion Criteria:
* Patients with any medical condition or circumstance that the investigator believes may compromise the data collected or lead to a failure to fulfil the study requirements
* Patients who are planned to have an Iodinated contrast agent with computed tomography (CT) or gadolinium based contrast agent with MRI or other PET radiotracer \< 24 hours prior to the PET scan
* Patients with contraindication to undergo MRI
* Patients with extreme claustrophobia
* Patients with prior allergy to MRI contrast agent
* Patients who are cognitively impaired
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.
