Summary
This trial studies if using PSMA PET scans to select patients for Ra-223 radiation therapy is effective in treating prostate cancer that has spread to bones.
Who is the study for?
This trial is for men aged 18+ with castration-resistant prostate cancer that has spread to bones, but not beyond. They must have low testosterone levels and be in fairly good health overall. Participants need a positive PSMA PET scan result and can't have had certain previous cancer treatments or high bone involvement by the cancer.
What is being tested?
The study tests if PSMA PET scans are effective in selecting patients who would benefit from Ra-223 radiation therapy. Ra-223 targets bone metastases from prostate cancer. The trial will assess how well this targeted radiation works after identifying tumor activity through advanced imaging techniques.
What are the potential side effects?
Potential side effects of Ra-223 include nausea, diarrhea, blood cell count changes leading to anemia or infection risks, and symptoms related to where the radiation is absorbed in the body such as bone pain.

Experimental Treatment
Group I: Treatment (NaF PET/CT/MDP, Ra-223, PSMA PET)Experimental Treatment3 Interventions
Patients undergo NaF PET/CT or MDP scan within 45 days prior to cycle 1 day 1. Patients then receive standard of care Ra-223 IV on day 1 of each cycle. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo PSMA PET/CT over 45-60 minutes between 30-60 days after the last dose of Ra-223. Patients also undergo collection of blood samples during screening, on day 1 of every Ra-223 cycle, and at 30 days after the last dose of Ra-223. Patients may also undergo NaF PET/CT or MDP scans during Ra-223 treatment as clinically indicated, and/or CT scans during screening and Ra-223 treatment as clinically indicated.
