Adenosine Signaling Modulation and Immune Checkpoint Inhibition With Hormone Sensitive Oligometastatic Prostate Cancer (NCT05915442)
๐ฉบ Plain-English Summary (8th-Grade Level)
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, ฮฑ-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.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (28 items) and avoid the listed exclusions (29 items).
Location: Columbia University Irving Medical Center / NewYork-Presbyterian Hospital โ New York, New York
๐ "Do I Qualify?" โ 1-Minute Self Screener
Instant ChecklistCheck every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).
Usually NOT eligible if any of the following apply:
- Exclusion Criteria:
- Patient may not have had prior systemic therapy, with the exception of androgen deprivation therapy (ADT) associated with treatment of the primary prostate tumor or with salvage radiation therapy. The ADT could not exceed 3-years in duration and must have occurred greater than 6 months before time of enrollment.
- Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- Spinal cord compression or impending spinal cord compression.
- Pulmonary and/or liver metastases \> 1.0cm in largest dimension.
- History of malignancy other than prostate cancer within 2 years prior to screening, except for malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate \> 90%), such as nonmelanoma skin carcinoma or ductal carcinoma in situ.
- Use of other investigational agents or treatment protocol.
- Treatment with therapeutic oral or intravenous (IV) antibiotics within 2 weeks prior to initiation of study treatment with the exception of patients receiving prophylactic antibiotics (e.g., to prevent a urinary tract infection or chronic obstructive pulmonary disease exacerbation) are eligible for the study.
- Inability to swallow medications.
- Malabsorption condition that would alter the absorption of orally administered medications.
- Grade โฅ 3 hemorrhage or bleeding event within 28 days prior to initiation of study treatment.
- History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan.
