Study Details

Study Description

Brief Summary

To evaluate the following items in patients with advanced cholangiocarcinoma receiving lenvatinib plus paclitaxel treatment, Primary endpoint: Overall response rate (ORR) by RECIST 1.1 Secondary endpoints Progression-free survival (PFS) Time to progression Overall survival Disease control rate (Overall response rate + stable disease ≧ 4 weeks) Response rate by modified RECIST Association between therapeutic efficacy and tumor vascularity Quality of life Safety profile Predictive biomarker of cholangiocarcinoma

Condition or Disease	Intervention/Treatment	Phase
Advanced Biliary Tract Cancer	Drug: Lenvatinib Pill,Paclitaxel	Phase 2

Detailed Description

Safety run-in phase: 3-6 cases Traditional 3+3 design is applied for the determination of initial lenvatinib dose.
Extension phase:

The estimated number of patients in current trial is calculated with Simon's minimax two-stage analysis. Considering the response rate is at least 10% higher (based on Ueno's data) than the 5% response rate of mFOLFOX in patients who fail gemcitabine plus cisplatin in ABC-06 trial, the assumption of response rate of lenvatinib plus paclitaxel will is 15% or higher. Therefore, Simon's minimax two-stage design is applied with P0 = 5%, P1 = 15%, error 0.10, and errors 0.20. If tumor response is not observed in the first 29 patients, the study will be stopped. Otherwise, 15 additional patients be accrued for a total of 44. The null hypothesis will be rejected if 5 or more subjects have tumor response to the treatment of lenvatinib plus paclitaxel in 44 patients. If the investigators assume that drop-out rate is 10%, total accrual patient will be 49.

Total case number = patients in safety run-in phase + patients in extension phase = (3 -

- 49 = 52 - 55

Eligibility Criteria

Criteria

Ages Eligible for Study:

20 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

1. Patients with age ≧20 years old.
2.Histologically confirmed biliary tract cancer which is locally advanced, recurrent or metastatic disease. The disease entities include intrahepatic cholangiocarcinoma, perihilar cholangiocarcinoma, distal bile duct cholangiocarcinoma, Ampulla of Vater cancer, and gallbladder cancer.

3.Documented disease progression during or within 6 months after gemcitabine-based (regimens containing gemcitabine plus cisplatin, gemcitabine plus S-1, or gemcitabine plus oxaliplatin) chemotherapy. Patient who has received antiangiogenetic agent (bevacizumab, ramucirumab, lenvatinib), taxane-based chemotherapy, or more than 1 line of chemotherapy for locally advanced or metastatic biliary tract cancer is ineligible.
