Study of DKN-01 and Gemcitabine/Cisplatin in Patients With Carcinoma to Primary to the Intra- or Extra-Hepatic Biliary System or Gallbladder

In Part A, escalating doses of DKN-01 will be administered to different cohorts of patients to evaluate safety and dose limiting toxicities (DLTs) and to establish the maximum tolerated dose of DKN-01 when administered in combination with gemcitabine and cisplatin. Part B is an expansion cohort in which patients are treated at the MTD of DKN-01 (or highest dose tested if the MTD is not defined) to further characterize safety, tolerability, pharmacokinetics and efficacy within the defined patient population.
