  -  Mesothelioma
  -  Thyroid Carcinoma
  -  Salivary Gland Carcinoma (sarcomas and mesenchymal tumors are excluded)
  -  OR
  -  Any advanced solid tumor, with the exception of colorectal carcinoma (CRC), which is Microsatellite Instability (MSI)-High (MSI-H)
  -  Progression of tumor or intolerance to therapies known to provide clinical benefit. There is no limit to the number of prior treatment regimens
  -  Can supply tumor tissue for study analyses (dependent on tumor type)

  Exclusion Criteria:
  -  Currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of study medication

  -  Active autoimmune disease that has required systemic treatment in the past 2 years
  -  Prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or not recovered from an adverse event caused by mAbs administered more than 4 weeks earlier
  -  Prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks of study Day 1 or not recovered from adverse events caused by a previously administered agent
  -  Known additional malignancy within 2 years prior to enrollment with the exception of curatively treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin and/or curatively resected in situ cancers
