• Exclusion

1. Subjects who were treated with surgery, radiotherapy, chemotherapy or investigational therapy within 2 weeks (note: placement of biliary stent is allowed)

2. Subjects who have uncontrolled CNS metastases (patients who require steroids should be on a stable or decreasing dose for at least 2 weeks)

3. Subjects who have any contraindications for 5-FU, leucovorin, or oxaliplatin

4. Subjects who have moderate or severe cardiovascular disease

• Subjects who have myocardial infarction, unstable angina pectoris, New York Heart Association (NYHA) Class III/IV congestive heart failure, or uncontrolled hypertension within 6 months before screening

• Subjects who have major abnormalities at the Investigator's discretion based on electrocardiogram (ECG)and Doppler ECHO results at screening or within 14 days before screening

• Subjects who have increase in brain natriuretic peptide(BNP) or increase in troponin (over 99th percentile upper reference limit) at Screening (based on the normal range of relevant study center)

• Subjects who have risk factors for ascending aortic aneurysm such as genetic disorder and trauma and risk factors for aortic stenosis

• Subjects who have a history of heart or aorta surgery

5. Subjects who have clinically significant gastrointestinal bleeding within 4 weeks before screening

6. Subjects who have a known history or suspected hypersensitivity to any excipients of the investigational product or combination drug(s)

7. Subjects who have received prior treatment targeting the signaling pathway of TGF-β

8. Subjects who have a disease or condition that affects the mechanism of the investigational product, or are currently using or planning to use:

• Drugs that are exclusively or primarily eliminated by cytochrome P-450 isozyme (CYP) including CYP1A2, CYP2B6, or CYP3A4

• Drugs that are exclusively or primarily eliminated by UDP glucuronyltransferase (UGT) 1A1 (UGT1A1)

• Drugs that are substrates for the drug transporter multidrug resistance protein 1 (MDR1) have a narrow therapeutic window or are strong inhibitors of drug transporter MDR1

• Drugs that are strong inhibitors or inducers of CYP2D6 or CYP3A4

9. Subjects who are unable to swallow tablets

10. Subjects who have a history of or are suspected of drug abuse

11. Female subjects of child-bearing potential who have a positive result on a pregnancy test at screening or are unable to agree to use an effective barrier method of birth control to avoid pregnancy during the study period (e.g., sterilization, intrauterine contraceptive device, combination of oral contraception and barrier contraception, combination of other hormone delivery systems and barrier contraception, contraceptive cream, combination of cream, jelly, or form and diaphragm or condom)

12. Subjects, in the opinion of the Investigator, who are unsuitable to participate in the study

13. Subjects who were treated with other investigational products within 28 days before screening or within a period shorter than 5-timesthe half-life of the investigational product
