Completed · Phase 2

Conditions studied: Metastatic Urothelial Carcinoma, Bladder Cancer

In brief

This research study is examining the effectiveness of pembrolizumab plus cryoablation or aveluma plus cryoablation on people with urothelial carcinoma, including bladder cancer, that has spread.

PS ECOG 0 or 1
Laboratory requirements:
ANC > 1 x 109/L
Platelets > 75 x 109/L
ALT / AST < 5 x ULN
Total bilirubin <3 mg/dL
INR <1.7
CrCl >30 ml/min

You may not qualify if…

Lesion to undergo cryoablation cannot have had prior radiation therapy or other locoregional therapy
Inability to lie flat for the cryoablation procedure.
Known significant immunodeficiency due to underlying illness (e.g. HIV / AIDS) and/or blood CD4+ T cells <200/ul
History of autoimmune disease, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with anti-phospholipid syndrome, granulomatosis with polyangiitis, Sjogren's syndrome, Guillain- Barre syndrome, multiple sclerosis, vasculitis, or glomerulonephritis.
Patients with a history of autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone are eligible for this trial.
Patients with controlled Type I diabetes mellitus on a stable dose of insulin regimen are eligible for this trial.
Patients with history of vitiligo and controlled psoriasis are eligible for the trial.
Continued adverse events from a previously administered chemotherapeutic agents.
Grade 1 adverse events and ongoing toxicities such as alopecia are exempt
Treatment with systemic corticosteroids exceeding the equivalent of 10 mg/day of prednisone or other systemic immunosuppressive medications (including but not limited to prednisone, dexamethasone, cyclophosphamide, azathioprine, methotrexate, and anti-tumor necrosis factor [anti-TNF] agents) within 2 weeks prior to Day 1, or anticipated requirement for systemic immunosuppressive medications during the trial
Patients who receive acute, low-dose, systemic corticosteroid medications (e.g., a onetime dose of dexamethasone for nausea) or for prevention of hypersensitivity reactions to contrast agents may be enrolled in the trial.
Anticoagulant or anti-platelet medication that cannot be interrupted prior to cryoablation
Pregnant or lactating
History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicated the use of an investigational drug or that could affect the interpretation of the results or render the patient at high risk from treatment complications.
Prior treatment with immune checkpoint blockade therapies, including anti-CTLA-4, anti-PD-1, and anti-PD-L1 therapeutic antibodies
Treatment with systemic immunostimulatory agents (including but not limited to IFNs, interleukin [IL]-2) within 6 weeks or five half- lives of the drug, whichever was shorter, prior to Day 1.
Signs or symptoms clinically significant of infection within 2 weeks prior to Day 1.
Any other systemic anti-cancer treatment (including investigational agents) within 4 weeks prior to the first dose of study drug. Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy may be eligible
