Bladder Cancer Clinical Trial
Nivolumab for the Treatment of Patients With Metastatic Urothelial Cancer With ARID1A Mutation and Stratify Response Based on CXCL13 Expression
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.
I. To estimate objective response rate (ORR) and overall survival (OS) in patients with ARID1A mutations receiving nivolumab therapy.
II. To estimate objective response rate (ORR) and overall survival (OS) in patients with ARID1A mutations plus CXCL13-high expression and ARID1A mutations plus CXCL13-low expression, receiving nivolumab therapy.
I. To estimate progression free survival (PFS) in subjects with harboring ARID1A mutation treated with nivolumab monotherapy.
II. To estimate progression free survival (PFS) in subjects with ARID1A mutations plus CXCL13-high expression and ARID1A mutations plus CXCL13-low expression, treated with nivolumab monotherapy.
III. To assess peripheral and tumor infiltrating immune cell sub-populations in patients with ARID1A mutations, ARID1A plus CXCL13-high and ARID1A plus CXCL13-low expression, to determine predictors of response and resistance.
IV. To determine expression pattern of CXCL13 in ARID1A mutant tumors.
Patients receive nivolumab intravenously (IV) over 30 minutes on day 1. Cycles repeats 28 days (4 weeks) for up to 2 years in the absence of disease or unacceptable toxicity.
After the completion of study treatment, patients are followed up for 100 days, then every 3-6 months thereafter.
Patient will have a tumor harboring genomic mutation of ARID1A. ARID1A mutation testing will be performed as standard of care

Subjects must have progression or recurrence after treatment
With at least 1 platinum-containing chemotherapy regimen for metastatic or surgically unresectable locally advanced urothelial cancer, or

Evaluable tumor tissue (archived or new biopsy) must be provided for biomarker analysis as formalin-fixed paraffin-embedded (FFPE) tumor block or minimum of 10 slides. Archived tissue may be from prior biopsy of unresectable or metastatic disease or from prior surgical resection
Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
Prior palliative radiotherapy must have been completed at least 2 weeks prior to study drug administration. Patients must have measurable disease outside the radiation field to be eligible. Patients with progression in a previously radiated field will also be eligible
White blood cell count (WBC) >= 2000/uL (obtained within 7 days prior to first dose)
Neutrophils >= 1500/uL (obtained within 7 days prior to first dose)
Platelets >= 100 x1 x10^3/uL (obtained within 7 days prior to first dose)
Hemoglobin >= 9.0 g/dL (obtained within 7 days prior to first dose)
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3 x upper limit of normal (ULN) (or =< 5 X ULN for participants with liver metastases) (obtained within 7 days prior to first dose)
Total Bilirubin =< 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL (obtained within 7 days prior to first dose)
Serum creatinine =< 1.5 x ULN or creatinine clearance (CrCl) >= 30 mL/min (using the Cockcroft-Gault formula) (obtained within 7 days prior to first dose)
Re-enrollment: This study permits the re-enrollment of a subject that has discontinued the study as a pre-treatment failure (ie, subject has not been treated). If re-enrolled, the subject must be re-consented and inclusion/exclusion criteria reassessed
Patients are required to participate in PA13-0291 for correlative studies. Patients will need to consent for biopsy and peripheral blood collection as documented in the study calendar
Prior treatment with an anti-PD-1, anti-PD-L1, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways
Active brain metastases or leptomeningeal metastases. Subjects with brain metastases are eligible if these have been treated and there is no magnetic resonance imaging (MRI) evidence of progression for at least 4 weeks after treatment is complete and within 28 days prior to first dose of study drug administration. Where MRI is contraindicated CT scan is acceptable. Cases must be discussed with the medical monitor. Brain lesions are not considered measurable disease. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (> 10 mg/day prednisone equivalents) for at least 2 weeks prior to study drug administration
Any serious or uncontrolled medical disorder, that in the opinion of the investigator, may increase the risk associated with study participation or study drug administration, impair the ability of the subject to receive protocol therapy, or interfere with the interpretation of study results
Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, prostate cancer without evidence of prostate specific antigen (PSA) progression or carcinoma in situ such as the following: gastric, prostate, cervix, colon, melanoma, or breast for example
Subjects with active, known or suspected autoimmune disease. Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism, due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll
Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
All toxicities attributed to prior anti-cancer therapy other than neuropathy, alopecia and fatigue must have resolved to grade 1 (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] version 5) or baseline before administration of study drug. Subjects with toxicities attributed to prior anti-cancer therapy which are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum based therapy, are permitted to enroll. Neuropathy must have resolved to grade 2 (NCI CTCAE version 5)
Treatment with any chemotherapy, radiation therapy, biologics for cancer, or investigational therapy within 28 days of first administration of study treatment. Prior palliative radiotherapy must have been completed at least 2 weeks prior to study drug administration
