The purpose of this study is to find out if giving radiation therapy (RT) to areas of metastatic prostate cancer at the time a participant is diagnosed will help control disease better than the usual treatment. This treatment is called metastasis-directed radiotherapy (MDRT).
The usual treatment for prostate cancer that has spread to other parts of the body is to give lifelong treatment with hormone therapy (also known as androgen deprivation therapy or ADT). Participants may also be given prostate RT even if the disease is metastatic. Participants will receive hormone therapy (the standard treatment for prostate cancer) for 12 months. The hormone therapy agents may be taken by mouth or given as an injection. Participants will also have prostate RT. Up to 50 participants will have surgery to remove the prostate instead of having prostate RT. A portion of the participants will be randomized to receive MDRT to areas where the cancer has spread. For participants who have surgery to remove their prostate, they will be asked to allow tissue samples collected during the surgery to be sent to an outside lab for research tests and extra blood samples drawn for research tests before starting the study, and at the time the cancer becomes worse if applicable. Participation in the study will last approximately 12 months, and will be followed by their doctor for up to five years per standard of care.
The main goal is to compare the efficacy of the standard of care (standard systemic therapy + definitive prostate-directed local therapy) versus the standard of care with metastasis-directed radiotherapy (MDRT) for consolidation of metastatic disease.
Prostate cancer (PCa) is the most common cancer in men worldwide, with 10% diagnosed with metastatic disease at the time of presentation. The metastatic capacity of cancers behaves along a spectrum of disease progression, such that some solid tumors have spread widely before clinical detectability and others never metastasize. While metastatic disease has historically been treated with palliative intent, an oligometastatic state where metastases are limited in number and location has emerged in which participants with oligometastatic disease may benefit from effective local therapy in addition to systemic therapy. Systemic standard-of-care therapies often include androgen deprivation therapy (ADT) and Androgen receptor signaling inhibitor (ARSI). Studies have shown that administering local radiotherapy (RT) to the prostate in addition to standard of care may improve radiographic profession-free survival. It may be even more efficacious to add metastasis-directed radiotherapy (MDRT) to the treatment of oligometastatic prostate cancer cases. More research is necessary to investigate the application of MDRT to improve disease control.

| Overall survival (OS) | Overall Survival (OS) is defined as the time from randomization until death due to any cause. For participants who survive, time to death will be censored at the time of last contact. The distributions of OS for each treatment arm will be plotted using the Kaplan-Meier method, and median values for each will be estimated and reported with 95% CIs for each treatment arm and compared using stratified log-rank tests. Univariable Cox proportional hazard models will be used to estimate the effect of MDRT on OS. |

Inclusion Criteria:
Participant must be ≥ 18 years of age.
Participant must have an ECOG performance status ≤ 1.
Histologic confirmation of prostate adenocarcinoma of the prostate gland, with evidence of metastasis on imaging by conventional imaging (MRI, CT, or 99mTc bone scan) or PSMA PET/CT. Biopsy of sites of metastasis is strongly encouraged, but not required.
Newly diagnosed disease with no prior treatment(surgery, radiation or systemic treatment, ie hormone therapy or chemotherapy) to the primary disease.
In participants who undergo only conventional imaging, oligometastatic disease is defined as 1-5 discrete metastatic sites in the bone and/or extra-pelvic lymph node (LN) stations.
Extra-pelvic LN stations are superior to the regional/pelvic LN stations. Pelvic LN stations commence at the bifurcation of the aorta and bifurcation of the proximal inferior vena cava to the common iliac veins.
In participants who undergo PSMA PET/CT (in the presence or absence of conventional imaging), oligometastatic disease is defined as 1-10 PSMA avid bone lesions and/or extra-pelvic LN stations. The MI-RADS reporting system will be followed to guide PSMA PET interpretation
In participants extra-pelvic nodal (M1a) disease only by PSMA PET/CT and M0 by conventional imaging (i.e. extra-pelvic LN did not meet size criteria by CT), participant must meet 2 of 3 following criteria in order to be eligible:
Adequate organ and marrow function to receive treatment per treating physician
Medically fit for treatment and agreeable to follow-up.
Ability to understand and the willingness to sign a written informed consent.
