New treatment option for Oligometastatic Prostate Cancer
Official title Adenosine Signaling Modulation and Immune Checkpoint Inhibition With Hormone Sensitive Oligometastatic Prostate Cancer
ClinicalTrials.gov ID: NCT05915442
What this study is testing
What is Quemliclustat?
Quemliclustat is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for oligometastatic prostate cancer.
Also referred to as AB680.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- 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.
