  • Abdomen/pelvis computed tomography (CT) or magnetic resonance imaging (MRI) scan
  • Chest x-ray or CT scan.

• Patients with concurrent urothelial carcinoma and/or related variants anywhere outside bladder

• Patients who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury =< 4 weeks prior to registration, or who have not recovered from side effects of such procedure or injury prior to registration.

  • NOTE: Patients who have had minor procedures (i.e. TURBT) or percutaneous biopsies prior to registration are eligible.
• Patients with history of cirrhosis, alcoholic or non-alcoholic steatohepatitis (NASH), auto-immune hepatitis, or previous grade 3-4 drug-related hepatitis.
• Patient with history of prior solid organ or allogeneic bone marrow transplant.

• Clinically significant cardiac diseases, including any of the following:

• History of untreated human immunodeficiency virus (HIV)

  • NOTE: There is no requirement to screen patients for HIV. Patients with history of HIV infection are allowed if on effective highly active antiretroviral therapy (HAART) therapy and CD4 count more than 250.

• History of active hepatitis B infection

  • NOTE: There is no requirement to screen patients for hepatitis B.

• Known diagnosis of any condition (i.e. post-hematopoietic or organ transplant, rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, etc.) that requires chronic immunosuppressive therapy.

  • NOTE: Usage of non-steroidal anti-inflammatory medications (NSAIDS) for the treatment of osteoarthritis and uric acid synthesis inhibitors for the treatment of gout are permitted. For questions, please consult the study chair.
• Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g. active or uncontrolled infection, uncontrolled diabetes) that could cause unacceptable safety risks or compromise compliance with the protocol.
• Pregnant or breast-feeding women.
