Brief Summary:

This is a single arm phase 2 study of Single Tremelimumab with Regular Interval Durvalumab (STRIDE) plus Gemcitabine and Cisplatin (GEMCIS) in locally advanced unresectable/metastatic combined hepatocellular-cholangiocarcinoma (cHCC-CCA). Cycles 1 through 8 will be in 3 week intervals and Cycles 9+ will be in 4 week intervals. Tremelimumab is administered at 300mg intravenously once at Cycle 1. Durvalumab is administered at 1500mg intravenously every 3 weeks for Cycles 1-8, then every 4 weeks for Cycles 9+. Gemcitabine is administered at 1000mg/m\^2 intravenously on Day 1 and Day 8 of Cycles 1-8 only. Cisplatin is administered at 25mg/m\^2 intravenously on Day 1 and Day 8 of Cycles 1-8 only. Subjects will require a visit with appropriate laboratory work prior to the start of each cycle. Disease assessment will occur at screening and then every 9 weeks until the end of Cycle 9. Disease assessments will then occur every 8 weeks. Subjects will continue treatment until progression per RECIST 1.1, toxicity or subject/physician decision. A maximum of 24 months treatment from Cycle 1 Day 1 is allowed.

Subjects that have untreated central nervous system (CNS) metastases and/or carcinomatous meningitis identified either on the baseline brain imaging obtained during the screening period or identified prior to signing the ICF are not eligible to participate. Subjects whose brain metastases have been treated may be eligible provided they show radiographic stability (defined as 2 brain scans, both of which are obtained after treatment to the brain metastases. These imaging scans should both be obtained at least four weeks apart and show no evidence of intracranial progression). In addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have resolved or be stable either, without the use of steroids, or are stable on a steroid dose of ≤ 10mg/day of prednisone or its equivalent and anti-convulsants ≤ 14 days prior to registration.

            • 21. Known active hepatitis infection, positive hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg) or HBV core antibody (anti-HBc), at screening. Subjects with a past or resolved HBV infection (defined as the presence of anti HBc and absence of HBsAg) are eligible. Subjects positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
