Study of Oxaliplatin, Irinotecan, and S-1 in Biliary Tract Cancer

Phase 2

• Conditions: Biliary Tract Neoplasm
• Interventions: Drug: Oxaliplatin, Irinotecan, S-1

• Registration Number: NCT02527824
• Lead Sponsor: Hallym University Medical Center

Brief Summary

This study will conduct a phase II study of triple combination with oxaliplatin, irinotecan, and S-1 as the first-line chemotherapy in patients with advanced biliary tract cancer.

Detailed Description

It is widely accepted that the efficacy of chemotherapy for patients with inoperable, advanced, and metastatic biliary tract cancer is better than that compared to best supportive care. In general, gemcitabine based combination chemotherapies are considered as the first line treatment for patients with advanced biliary tract cancer, but these have some limitations of inconvenience of administration and unsatisfactory efficacy.

S-1 monotherapy and combination with oxaliplatin have shown the objective response rate of 21-35% and 24.5%, respectively, and irinotecan combined with oxaliplatin has shown the response rate of 18-20.5% in patients with advanced metastatic biliary tract cancer. So the investigators had conducted the phase I study of three drugs (oxaliplatin, irinotecan, and S-1) with modification of dosage and schedule and will conduct a phase II study with recommended dose of triple chemotherapy from this phase I study.

Primary Outcome Measures

Name	Time	Method
overall response rate	1.5 year	Tumor response will be classified on the basis of the response evaluation criteria in solid tumors (RECIST) guidelines version 1.1

Secondary Outcome Measures

Name	Time	Method
progression free survival	1.5 year	The progression-free survival (PFS) will be measured from the start of study treatment until documented tumor progression (by RECIST) or death due to any cause
toxicity profiles - the number of participants and grade of intensity of treatment related adverse events	1.5 year	adverse events will be graded using the NCI common terminology criteria for adverse events (NCTCAE) v 4.0
overall survival	1.5 year	The overall survival (OS) will be estimated from the start of study treatment until participant's death and measured using the Kaplan-Meier method
