Aflibercept in Combination With FOLFIRI as First-line Chemotherapy in Patients With Metastatic Colorectal Cancer (mCRC): A Phase II Study (FFCD 1302)

Abstract Background FOLFIRI (irinotecan, 5-fluorouracil, and leucovorin) + aflibercept improves median overall survival (OS) and progression-free survival (PFS) in patients with previously treated metastatic colorectal cancer (mCRC). Our aim was to investigate efficacy and tolerability of this combination in the first line. Patients and Methods Patients with untreated documented mCRC received aflibercept plus FOLFIRI every 14 days until progression or unacceptable toxicity in an open, phase II single-arm, multicenter trial. The primary endpoint was the 6-month PFS rate. Secondary endpoints were OS and tolerability. A 2-step Simon design was used with H0: 55% and H1= 75%. Data were analyzed …
