Radium-223 in Biochemically Recurrent Prostate Cancer
United States19 participantsStarted 2020-09-22
Plain-language summary
Background:
Some men who have been treated for localized prostate cancer with surgery or radiation still show signs of the disease in their blood. This is called biochemically recurrent prostate cancer. Radium-223 is a small molecule. It uses radiation to kill cancer cells and improves survival in advanced prostate cancer. Researchers want to see if it can treat prostate cancer and induced immune changes earlier in the disease when the cancer is only detectable by prostate specific antigen (PSA) in the blood.
Objective:
To learn how Radium-223 affects men with rising PSA but no evidence of cancer on conventional CT or bone scan, but positive findings on PET or molecular imaging in the bones. The primary focus is impact on the immune system with secondary focus on impact on PSA and imaging.
Eligibility:
Men ages 18 and older with prostate cancer who have had surgery and/or radiation, but their PSA is rising even though no disease is visible on routine imaging scans (CT or bone scans). Patients are required to have PET or molecular imaging findings in bones, but not organs (lymph nodes are allowed).
Design:
Participants will be screened with a medical history and physical exam. Their ability to do normal tasks will be reviewed. They will give tissue samples or a report from their doctor about their cancer. They will have blood and urine tests. They will have an electrocardiogram to measure heart function. They will have a scan of their chest and abdomen using radiation or magnetic resonance imaging. They will have a bone scan with injection of Tc99. They will have a positron emission tomography scan with intravenous (IV) injection of 18F-NaF.
Participants will get Radium-223 by IV. For this, a small plastic tube is put into an arm vein. Radium-223 will be given on Day 1 of each cycle (1 cycle = 4 weeks) for up to 6 cycles. Participants will repeat the screening tests during the study. They will also complete Quality of Life Surveys and give stool samples.
After treatment, participants will have long-term follow-up every 6 weeks for the rest of their lives.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* INCLUSION CRITERIA:
* Histopathological confirmation of prostate adenocarcinoma confirmed in either the Laboratory of Pathology at the National Institutes of Health (NIH) Clinical Center, or Walter Reed National Military Medical Center prior to enrollment. If no pathologic specimen is available, participants may enroll with a pathologist s report showing a histologic diagnosis of prostate cancer and a clinical course consistent with the disease.
* Biochemical progression after definitive surgery or radiation define as follows:
* Participants must have a detectable PSA
* Negative CT scan/MRI and Tc99 bone scan for metastatic prostate cancer. (Only Tc99 will be used to detect bone lesions, CT/MRI would be used to detect soft tissue lesions)
* Presence of findings on PET scan (i.e., NaF PET scan) suspicious for metastatic prostate cancer in bone. Note: while lymph node findings would be allowed and provide the opportunity for the assessment of any abscopal effects, PET scan findings suggesting visceral disease will be excluded.
* Testosterone \>= 100 ng/dL
* ECOG performance status of 0 1
* Recovery from acute toxicity related to prior therapy, including surgery and radiation, (defined as no toxicity \>= grade 2).
* Hematological eligibility parameters (within 16 days before treatment initiation):
* Granulocyte count \>= 3,000/mm\^3
* Absolute neutrophil count (ANC) \>= 1,500/mm\^3
* Platelet count \>= 100,000/mm\^3
* Hgb \>= 10 g/dL
* Hepatic function eligibility par…
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?
