Summary

This trial is testing a new combination of treatments for prostate cancer that has spread to a few other parts of the body.

Who is the study for?
Men over 18 with newly diagnosed hormone-naive oligometastatic prostate cancer, who haven't had chemotherapy or surgery for it, and have fewer than four metastases. They must be able to consent, have good organ function and performance status (able to carry out daily activities), agree to use contraception, and not be on certain other treatments.
What is being tested?
The trial is testing the combination of radiation therapy and pembrolizumab immunotherapy with or without SD-101 injected into tumors in patients with limited-spread prostate cancer. It's an open-label Phase 2 study where everyone knows what treatment they're getting.
What are the potential side effects?
Possible side effects include immune-related reactions affecting organs, fatigue, skin reactions at injection sites, changes in blood tests reflecting liver or kidney issues. Pembrolizumab can also cause infusion-related symptoms like fever or chills.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Cohort 2: Prostate and Oligometastatic sites (ADT, SBRT, Pembrolizumab, SD-101)Experimental Treatment6 Interventions
Three month androgen deprivation therapy (ADT) run-in followed by leuprolide injected intramuscularly every 3 months for 3 doses (or another FDA approved gonadotropin-releasing hormone agent for 9 months) + abiraterone by mouth daily with prednisone by mouth daily (or equivalent medication per local standard practice) for 9 months starting on Day 1. TLR9 agonist SD-101: Injected into the dominant prostatic tumor lesion at time of fiducial marker placement (1-5weeks prior to Cycle 1 Day 1) and 1-3 weeks after Cycle 1 Day 1 Pembrolizumab: Given IV every 21 days for up to 13 doses Radiotherapy: Given every other day over 10-14 days delivered to the whole prostate gland and oligometastatic sites via stereotactic body radiation therapy (SBRT) starting 1-2 weeks after marker placement.
