Overview

Study Title

A Phase II Open Label Single Arm Study of Adjuvant Nivolumab following Chemo-Radiation in localized Muscle-Invasive Bladder Cancer (NEXT)

Summary

This is a phase 2, single arm, open label trial to evaluate the rate of failure free survival at 2 years after start of chemoradiation with adjuvant nivolumab in adult subjects who undergo chemoradiation for localized bladder cancer.

Objective

The primary purpose of this study is to evaluate the ability of checkpoint inhibition with nivolumab to enhance the efficacy of chemoradiation in localized bladder cancer to reduce the rates of loco regional and distant recurrence without added toxicity. - Primary Objectives and Endpoint The primary objective is to evaluate the two-year rate of failure-free survival (FFS). The definition of failure will include loco-regional recurrence, and distant recurrence. The primary endpoint of the FFS will be determined based on disease recurrence date defined as the time between the start date of study treatment (nivolumab) and the date of first recurrence or non-cancer related death. Secondary Objectives and Endpoint - Evaluate the rate of failure-free survival at two years in subjects with intact bladder (FFSIB). This will be measured only in subjects who do not have local recurrence requiring radical cystectomy. The endpoint of FFSIB will be determined based on disease recurrence date defined as the time between the start date of study treatment (nivolumab) and the date of first recurrence or non-cancer related death. - Evaluate the rate of acute and late grade 2 or higher treatment-related GU, GI, hematologic, and immune related toxicity. The incidence of adverse events will be collected and tabulated through treatment and follow up. - Evaluate the effect of treatment on Quality of Life. The endpoint will include the completion of quality of life questionnaires as per study calendar. - Evaluate cystoscopic local control at 6 months, 1 year and 2 years post start of study treatment with nivolumab after censoring for distant recurrence. The endpoint will be measurement of local recurrence at 6 months, 1 year and 2 years as determined by cystoscopy. - Evaluate the rate of salvage cystectomy. This will be measured by the endpoint of radical cystectomy for local recurrence during study treatment. - Evaluate the rate of distant failure-free survival at two years in subjects with intact bladder and those who discontinue study to undergo salvage cystectomy. This will be measured in subjects who do and do not have local recurrence requiring radical cystectomy during study treatment. The endpoint FFS will be determined based on disease recurrence date defined as the time between the start date of study treatment (nivolumab) and the date of first distant recurrence or non-cancer related death. - Evaluate overall survival up to 5 years. This will be measured by the rate of death for up to 5 years from start of study treatment. Exploratory Objectives: - To asses immunological monitoring on peripheral blood mononuclear cells and other humoral factors collected prior to the initiation of chemoradiation, study therapy, and throughout the study drug administration, to characterize changes in immune cell and immune factor subsets that can be correlated with clinical outcome. - To assess the correlation of response to PD-L1 expression in pretreatment tumor tissue in the study subjects

Inclusion Criteria

Inclusion Criteria:

18 years of age or older

Patients with muscularis propria invasion clinical stages 2 to 4 (T2-4a, N0 or N+, M0 or T1 with N+), who are not candidates for radical cystectomy. Patients may have undergone partial cystectomy for removal of bladder tumor prior to chemoradiation. Staging is determined prior to chemoradiation

Patients have been evaluated by a urologic oncologist to determine eligibility for radical cystectomy prior to chemoradiation. Patients may not be candidates for radical cystectomy due to one or more reasons such as but not limited to comorbidities, age, surgical risk or patient refusal to undergo radical cystectomy. Patients who refuse to undergo radical cystectomy are not required to be evaluated by a urologic oncologist.

Patients must have histologically proven primary carcinoma of the bladder or urethra or lower ureter (adenocarcinoma or transitional or squamous-cell carcinoma)

Treating investigator has determined that the patients are not a candidate for radical cystectomy. Patients have been evaluated by a urologic oncologist to determine eligibility for radical cystectomy prior to chemoradiation. Patients may not be candidates for radical cystectomy due to one or more reasons such as, but not limited to, comorbidities, age, surgical risk, or patient refusal to undergo radical cystectomy.

Tumor tissue from the most recently resected site of disease (preferable) or from the transurethral resection that yielded the initial muscle invasive diagnosis must be provided for biomarker correlative analyses. Enrollment is permitted if adequate archived tissue is unavailable.

Patients must have received systemic radiosensitizing chemotherapy with definitive pelvic radiation therapy. Patients may have received partial amount of chemotherapy and radiation (both) to be eligible.

Platinum based chemotherapy prior to chemoradiation is permitted but not mandatory

Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤2

Adequate bone marrow and organ function as indicated by lab values per protocol.

Able to start study treatment within 90 days of completion of chemoradiation.

Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 5 months after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.

Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 7 months after the last dose of study therapy.

All toxicities attributed to prior anti-cancer therapy other than nephropathy, neuropathy, hearing loss, alopecia and fatigue must have resolved to Grade 1 (NCI CTCAE version 4.03) 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.

Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines.

Exclusion Criteria

Exclusion Criteria:

Evidence of distant metastases or lymph node metastasis (es) that was not within the radiation field.

Known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin. A history of localized early stage malignancy that has undergone potentially curative therapy or is low grade and does not require active treatment is allowed.

Diffuse bladder carcinoma in situ (CIS) that was not able to be encompassed in a boost radiotherapy volume

Patients with inflammatory bowel disease

Patients 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.

Patients with a condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 day of study drug administration. Inhaled, ocular, intraarticular, intranasal and topical steroids are permitted.
