A Study of Irinotecan, Levofolinate, and 5-Fluorouracil (FOLFIRI) Plus Ramucirumab (IMC-1121B)

The primary objective of this study is to investigate the safety and tolerability of the anti-vascular endothelial growth factor receptor-2 (anti-VEGFR-2) monoclonal antibody Ramucirumab (IMC-1121B) in combination with irinotecan, levofolinate, and 5-fluorouracil (FOLFIRI) in Japanese participants with advanced colorectal carcinoma (CRC).

Inclusion Criteria:

* Participant is Japanese
* Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
* Has histologically or cytologically confirmed CRC
* Has metastatic disease that is not amenable to potentially curative resection
* Has received no more than 2 prior systemic chemotherapy regimens in any setting (only 1 prior regimen for metastatic disease is permitted)
* Has received first-line combination therapy of bevacizumab, oxaliplatin, and a fluoropyrimidine for metastatic disease and has experienced disease progression during first-line therapy, or disease progression within 6 months after the last dose of first-line therapy, or discontinued part or all of first-line therapy due to toxicity and experienced disease progression within 6 months after the last dose of first-line therapy. Participants must have received a minimum of 2 doses of bevacizumab as part of a first-line regimen containing chemotherapy in order to enroll.
* Has adequate hepatic, renal, hematologic, and coagulation function
* The participant's urinary protein is ≤1+ on dipstick or routine urinalysis. If urine dipstick or routine analysis indicates proteinuria ≥2+, then a 24-hour urine must be collected and must demonstrate \<1000 milligrams (mg) of protein in 24 hours to allow participation in the study

Exclusion Criteria:

* Has received bevacizumab within 28 days prior to study registration
* Has received chemotherapy within 21 days prior to study registration
* Has received any previous systemic therapy (other than a combination of bevacizumab, oxaliplatin, and a fluoropyrimidine) for first-line treatment of metastatic CRC
* The participant experienced any of the following during first-line therapy with a bevacizumab-containing regimen: an arterial thrombotic/thromboembolic event; Grade 4 hypertension; Grade 4 proteinuria; a Grade 3-4 bleeding event; or bowel perforation
* Has received wide-field (full-dose pelvic) radiotherapy within 28 days prior to study registration
* Has undergone major surgery within 28 days or subcutaneous venous access device placement within 7 days prior to study registration
* Has elective or planned surgery to be conducted during the trial
* Has a history of deep vein thrombosis or pulmonary embolism within the past 12 months

* Has known human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS)-related illness
* Has known leptomeningeal or brain metastases or uncontrolled spinal cord compression
