Criteria

Inclusion Criteria:

1. The patient is 20-year-old or older on the day that consent is provided.

2. With histologically or cytologically proven metastatic colorectal adenocarcinoma.

3. Have measurable lesions according to RECIST v1.1.

4. Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 to 2.

5. Adequate organ function as defined below:

i. White blood cells (WBC) ≥3,000/μL ii. Absolute neutrophil count ≥1,500/μL iii. Platelets ≥1 x 105/μL iv. Hemoglobin ≥9.0 g/dL v. Total bilirubin ≤1.5 x the upper limit of normal (ULN) vi. AST(SGOT)/ALT(SGPT) ≤3 x ULN (or ≤5 x ULN if liver metastases are present) vii. Serum creatinine ≤1.5 x ULN

9. Female patients of childbearing potential must have a negative urine or serum pregnancy test.

10. Patients in reproductive age must be willing to use adequate contraception (refer to Section 8.4.2 of the protocol for adequate contraception methods) during the study and 3 months after the end of the study.

11. Ability to understand and the willingness to provide a written informed consent document.
