Criteria
Inclusion Criteria:

- Patient must have at least one and up to three asymptomatic metastatic tumor(s) of the
bone or soft tissue develop within the past 6-months that are ≤ 5.0 cm or <250 cm3.

- Patient must have had their primary tumor treated with surgery and/or radiation.

- Histologic confirmation of malignancy (primary or metastatic tumor).

- PSADT <15 months. PSA doubling time (PSADT) will be calculated using as many PSA
values that are available from time of relapse (PSA > 0.2). To calculate PSADT, the
Memorial Sloan Kettering Cancer Center Prostate Cancer

Prediction Tool will be used. It can be found at the following web site:

https://www.mskcc.org/nomograms/prostate/psa-doubling-time.

- Patient may have had prior systemic therapy and/or ADT associated with treatment of
their primary prostate cancer. Patient may have had ADT associated with salvage
radiation therapy (to the primary prostate cancer or pelvis is allowed).

- PSA >1 but <50.

- Testosterone > 125 ng/dL.

- Patient must have a life expectancy ≥ 12 months.

- Patient must have an ECOG performance status ≤ 2.

- Patient must have normal organ and marrow function as defined as:

Leukocytes >2,000/μL Absolute Neutrophil Count >1,000/μL Platelets >50,000/μL

- Patient must have the ability to understand and the willingness to sign a written
informed consent document.

Exclusion Criteria:

- No more than 3 years of ADT is allowed, with the most recent ADT treatment having
occurred greater than 6 months prior to enrollment.

- DCFPyL-PET/MRI or DCFPyL-PET/CT scan within the past 6 months with results that
demonstrate more disease lesions than baseline CT/Bone Scan

- Castration-resistant prostate cancer (CRPC).

- Suspected pulmonary and/or liver metastases (greater >10 mm in largest axis).

- Patient receiving any other investigational agents.

- Patient is participating in a concurrent treatment protocol.

- Total bilirubin > 3 times the upper limit of normal.

- Liver Transaminases > 5-times the upper limit of normal.

- Unable to lie flat during or tolerate PET/MRI, PET/CT or SBRT.

- Liver Transaminases > 5-times the upper limit of normal.

- Prior salvage treatment to the primary prostate cancer or pelvis is allowed.

- Refusal to sign informed consent.
