About this study
Official title: A Phase II Clinical Trial to Investigate ARID1A and/or KDM6A Mutation and CXCL13 Expression in the Pre-treatment Tumor Samples as a Combinatorial Predictive Biomarker for Immune Checkpoint Therapy in Metastatic Urothelial Cancer
This phase II trial studies the effect of nivolumab in urothelial cancer that has spread to other places in the body (metastatic), specifically in patients with aberrations in ARID1A gene (ARID1A mutation) and correlate with expression level of CXCL13, an immune cytokine. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab may help control the disease in patients with urothelial cancer or solid tumors. This trial aims at enriching patient selection based on genomic and immunological attributes of the tumor.

PRIMARY OBJECTIVE:
- To estimate objective response rate (ORR) and overall survival (OS) in participants with ARID1A and/or KDM6A mutations receiving nivolumab and relatlimab combination therapy. II.

SECONDARY OBJECTIVES:
- To estimate progression free survival (PFS) in subjects with harboring ARID1A and/or KDM6A mutation treated with nivolumab and relatlimab combination therapy.
II. To estimate progression free survival (PFS) in subjects with ARID1A and/or KDM6A mutations plus CXCL13-high expression and ARID1A and/or KDM6A mutations plus CXCL13-low expression, treated with nivolumab and relatlimab combination therapy.
III. To assess peripheral and tumor infiltrating immune cell sub-populations in patients with ARID1A mutations, KDM6A mutations, ARID1A plus CXCL13-high and ARID1A plus CXCL13-low expression, KDM6A plus CXCL13-high and KDM6A plus CXCL13-low expression, to determine predictors of response and resistance.
IV. To determine the expression pattern of CXCL13 in ARID1A and/or KDM6A mutant tumors

What is being measured
The primary outcome is the main question the study is designed to answer.
Objective response rate (ORR)

In addition, will also calculate the posterior probability that ORR is bigger in CXCL13 high group than in the CXCL low group.
Measured: Up to 2 years
Overall survival (OS)
The Kaplan-Meier method will be used to estimate the median OS and 1-year survival rate; the 95% confidence interval (CI) of the 1-year survival rate will also be reported.
Measured: From date of first study treatment to death due to any cause, assessed up to 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Diagnostic Laboratory Biomarker Analysis, Nivolumab and Relatlimab in people with Locally Advanced Bladder Urothelial Carcinoma and Locally Advanced Renal Pelvis Urothelial Carcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 18 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 6 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective response rate (ORR) (time frame: Up to 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2026.
