• Participants must be able to understand and be willing to sign the written informed consent form.

Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other study requirements.

Exclusion Criteria:

• Women who are pregnant or breast-feeding.
• Prior therapy with ramucirumab, bevacizumab, regorafenib or TAS 102.

• Any hemorrhage or bleeding event ≥ NCI CTCAE Grade 3 within 4 weeks prior to start of study medication.
• Any hemorrhage or bleeding event ≥ NCI CTCAE Grade 3 within 4 weeks prior to start of study medication.
• Persistent proteinuria ≥ Grade 3 on repeated measurement.
