Official title

Phase II Single Arm Study Testing SBRT, Adenosine Signaling Modulation (AB680, AB928), and Immune Checkpoint Inhibition (AB122) for Men With Hormone Sensitive Oligometastatic Prostate Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will evaluate the safety and effectiveness of a combination of study drugs including zimberelimab, etrumadenant, and quemliclustat in combination with metastasis-directed irradiation in men with hormone sensitive oligometastatic prostate cancer. The study aims to test the hypothesis that targeted inhibition of the adenosine signaling axis (quemliclustat (CD73 antagonist) + etrumadenant (A2AR/A2BR antagonist)) and immune checkpoint inhibition (zimberelimab, α-PD-1) in combination with metastasis-directed stereotactic body radiation therapy (SBRT) will improve local control, progression-free survival (PFS), and hormone therapy-free survival and mitigate immunosuppressive changes to the tumor microenvironment (TME), compared to SBRT alone.
