A Pilot Pre-Surgical Study Evaluating Anti-PD-L1 Antibody (Durvalumab) Plus Anti-CTLA-4 (Tremelimumab) in Patients With Muscle-Invasive, High-Risk Urothelial Carcinoma Who Are Ineligible for Cisplatin-Based Neoadjuvant Chemotherapy


Condition: Hydronephrosis, Infiltrating Bladder Urothelial Carcinoma Sarcomatoid Variant, Infiltrating Bladder Urothelial Carcinoma, Micropapillary Variant, Infiltrating Bladder Urothelial Carcinoma, Plasmacytoid Variant, Infiltrating Renal Pelvis Urothelial Carcinoma, Sarcomatoid Variant, Renal Pelvis Urothelial Carcinoma, Stage II Bladder Urothelial Carcinoma AJCC v6 and v7, Stage II Renal Pelvis Cancer AJCC v7, Stage II Ureter Cancer AJCC v7, Stage II Urethral Cancer AJCC v7, Stage III Bladder Urothelial Carcinoma AJCC v6 and v7, Stage III Renal Pelvis Cancer AJCC v7, Stage III Ureter Cancer AJCC v7, Stage III Urethral Cancer AJCC v7, Stage IV Renal Pelvis Cancer AJCC v7, Stage IV Ureter Cancer AJCC v7, Stage IV Urethral Cancer AJCC v7, Ureter Urothelial Carcinoma, Urethral Urothelial Carcinoma

Intervention:

  • Biological: Durvalumab
  • Procedure: Therapeutic Conventional Surgery
  • Biological: Tremelimumab

Purpose: This pilot phase I trial studies the side effects of durvalumab and tremelimumab in treating patients with muscle-invasive, high-risk urothelial cancer that cannot be treated with cisplatin-based therapy before surgery. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread.

  • Patients with the following high-risk features who are not candidates for traditional neoadjuvant chemotherapy will be included for this trial: micropapillary, sarcomatoid and plasmacytoid features; 3-dimensional (3-D) mass on exam under anesthesia (EUA); lymphovascular invasion; hydronephrosis (unless in the opinion of the treating physician, this is not due to tumor); high grade (grade 3) tumors of the ureter, renal pelvis, or tumors in these areas with radiographic abnormality large enough to recognize as an abnormal mass by computed tomography (CT) or magnetic resonance imaging (MRI) imaging; direct invasion of the prostatic stroma or the vaginal wall (i.e. cT4a disease); patients who are candidates for but refusing conventional chemotherapy may be considered eligible; for patients in whom eligibility is unclear, final arbitration will be determined by the principal investigator
  • Subjects must have no prior exposure to immunotherapy, such as, but not limited to other anti-CTLA-4, anti-PD-1, or anti-PD-L1 antibodies excluding vaccines
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
  • Able and willing to give valid written consent for available archival tumor samples or fresh tumor biopsies/resections

  • Hemoglobin >= 9 g/dL
  • Absolute neutrophil count >= 1,000/mm^3
  • Platelet count >= 100,000/mm^3
  • Total bilirubin =< 1.5 x upper limit of normal (ULN) except subjects with documented Gilbert's syndrome (> 3 x ULN), who must have a baseline total bilirubin =< 3.0 mg/dL
  • Subjects must be considered cisplatin ineligible as per treating physician due to renal dysfunction, or hearing impairment, or co-morbidities; cisplatin ineligibility defined as: glomerular filtration rate (GFR) less than 60 or; congestive heart failure (CHF) New York Heart Association (NYHA) class III or higher or; peripheral neuropathy grade 2 or higher or; Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2 or higher or; impaired hearing; patient's refusal of traditional chemotherapy
  • Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception from the time of screening, and must agree to continue using such precautions for 180 days after the final dose of investigational product; cessation of contraception after this point should be discussed with a responsible physician; periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception; they must also refrain from egg cell donation for 180 days after the final dose of investigational product
  • Nonsterilized males who are sexually active with a female partner of childbearing potential must agree to use a highly effective method of contraception from day 1 through 90 days after receipt of the final dose of investigational product; in addition, they must refrain from sperm donation for 90 days after the final dose of investigational product
  • Mild autoimmune conditions (such as localized psoriasis) requiring minimal treatment or systemic autoimmune conditions well controlled by target agents such as an anti-IL-17 that do not affect overall immune system; patients with a history of Hashimoto's thyroiditis only requiring hormone replacement, type I diabetes, or conditions not expected to recur in the absence of an external trigger are allowed to participate

Exclusion Criteria:

  • Concurrent enrollment in another clinical trial, unless in a follow-up period or it is an observational study
  • Any concurrent chemotherapy, immunotherapy, biologic, or hormonal therapy for cancer treatment; concurrent use of hormones for non-cancer-related conditions (e.g. insulin for diabetes and hormone replacement therapy) is acceptable

  • Known or suspected autoimmune disease; patients with a history of inflammatory bowel disease (including Crohn's disease and ulcerative colitis) and autoimmune disorders such as rheumatoid arthritis, systemic progressive sclerosis (scleroderma), systemic lupus erythematosus or autoimmune vasculitis (e.g., Wegener's granulomatosis) are excluded from this study; patients with a history of Hashimoto's thyroiditis only requiring hormone replacement, type I diabetes, or psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are allowed to participate; any condition requiring systemic treatment with corticosteroids (> 10mg daily prednisone equivalents) or other immunosuppressive medications within 14 days prior to first dose of study drug; inhaled steroids and adrenal replacement steroids doses > 10mg daily prednisone equivalents are permitted in the absence of active autoimmune disease

  • Females who are pregnant, lactating, or intend to become pregnant during their participation in the study
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, current pneumonitis, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, or psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the subject to give written informed consent
