Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To determine disease control rate (DCR) of TS-1® in patients with heavily pre-treated metastatic colorectal cancer

Secondary Objectives:

* To determine objective response rate (ORR)
* To determine time to progression (TTP)
* To determine overall survival (OS)
* To assess incidence of adverse events (AEs), serious adverse events (SAEs) \[Safety and Tolerability\]

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Simon's optimal two-stage design will be used to determine the sample size for this study.

• Stage I: \>1/9: The first 9 evaluable patients enrolled, \>1 (or ≥2) responders are required in order to enter the second stage, otherwise the trial will be terminated at the first stage due to futility.

• Stage II: Total \>8/34: For the total 34 evaluable patients, \>8 (or ≥9) responders are required to conclude the effectiveness of the study regimen.

The primary endpoint will be disease control rate which will be presented in frequency tabulation with two-sided 95% confidence interval (using binomial estimation).

The secondary endpoints are described as follows:

* ORR will be presented in frequency tabulation with two-sided 95% confidence interval;
* TTP will be estimated by Kaplan-Meier method with two-sided 95% confidence interval;
* OS will be estimated by Kaplan-Meier method with two-sided 95% confidence interval;
* Incidence of adverse events (AEs), serious adverse events (SAEs) \[Safety and Tolerability\] : assessed by CTCAE v4.0. Safety parameters will only be analyzed on the safety analysis set and be presented in frequency tabulation.

Group Type EXPERIMENTAL

S-1+leucovorin

Intervention Type DRUG

Eligible patients will receive TS-1 orally 40-60 mg (depending on patient's body surface area (BSA)) in combination with calcium folinate 30 mg twice a day for 7 days in a 2-week cycle.
