Enrollment: 62
Healthy volunteers: no

Brief summary:
Primary Objective:

To assess efficacy aflibercept + 5-fluorouracil (5-FU)/levofolinate/irinotecan (FOLFIRI) by objective response rate (ORR).

Secondary Objective:

To assess the following:

* safety profile;
* progression free survival (PFS);
* overall survival (OS);
* pharmacokinetics (PK);
* immunogenicity.

Detailed description:
Screening was up to 24 days. Treatment period was continued until DP, unacceptable toxicity, or participant's refusal. Follow up period was continued until death, participant's refusal, or end of study, whichever came first.

This trial was conducted in Japan, where the International Nonproprietary Name (INN) designation for the study molecule is "aflibercept" and this term is therefore used throughout the synopsis. In the US, the US proper name is "ziv-aflibercept".

Arms:
arm 1: Aflibercept 4 mg/kg intravenous (IV) infusion (1-2 hours) on Day 1 of Cycle 1 and every 2 weeks (q2w) thereafter, in combination with FOLFIRI regimen on Days 1-3 of Cycle 1 and q2w thereafter until disease progression (DP), unacceptable toxicity or participant's refusal. FOLFIRI regimen: IV infusions of levofolinate 200 mg/m\^2 (2 hours) and irinotecan 180 mg/m\^2 (90 minutes) simultaneously, followed by 5-FU 400 mg/m\^2 IV bolus injection followed by continuous IV infusion of 5-FU (46 hours) at 2400 mg/m\^2.

Interventions: intervention 1: Aflibercept intervention 2: Levofolinate intervention 3: Irinotecan intervention 4: 5-FU
Intervention descriptions: intervention 1: Pharmaceutical form: Concentrated solution (100 mg/4 mL \[25 mg/mL\], 200 mg/8 mL \[25 mg/mL\]) for infusion; Route of administration: Intravenous intervention 2: Pharmaceutical form: Solution for infusion (marketed formulation); Route of administration: Intravenous intervention 3: Pharmaceutical form: Solution for infusion (marketed formulation); Route of administration: Intravenous intervention 4: Pharmaceutical form: Solution for infusion (marketed formulation); Route of administration: Intravenous
