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

A Dose Escalation and Cohort Expansion Study of DKN-01 in Combination With Gemcitabine and Cisplatin in Patients With Advanced Carcinoma Primary to the Intra- or Extra-hepatic Biliary System or Gallbladder

DKN-01 is a humanized monoclonal antibody (Mab) with neutralizing activity against Dkk-1 and is being developed as an anti-neoplastic agent. This study is designed to evaluate the safety, tolerability, pharmacokinetics, and anti-tumor activity of DKN-01 in combination with gemcitabine and cisplatin in patients with carcinoma primary to the intra- or exta-hepatic biliary system or gallbladder.

Study Overview

• Status: Completed
• Conditions: Cholangiocarcinoma; Bile Duct Cancer; Carcinoma of Intrahepatic and Extra-hepatic Biliary System; Carcinoma of Gallbladder
• Intervention / Treatment: Drug: DKN-01; Drug: gemcitabine; Drug: cisplatin

Detailed Description

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.
