A multicenter, prospective, phase II trial of second-line aflibercept plus FOLFIRI in patients with metastatic colorectal cancer refractory to an anti-EGFR antibody: HGCSG1801.
Aflibercept (AFL) plus FOLFIRI prolongs overall survival (OS) in patients with metastatic colorectal cancer (mCRC). However, there is limited evidence on the efficacy and safety of AFL plus FOLFIRI previously treated with anti-epidermal growth factor receptor (EGFR) agents. Therefore, we conducted a prospective open-label phase II trial evaluating the efficacy and safety of AFL plus FOLFIRI in Japanese patients with mCRC failing a prior oxaliplatin-based chemotherapy plus an anti-EGFR agent. AFL (4 mg/kg iv) followed by FOLFIRI (irinotecan 180 mg/m2, leucovorin 200 mg/m2 iv, bolus 5-fluorouracil [5-FU] 400 mg/m2, and infusional 5-FU 2400 mg/m2/46 h) was given every 2 weeks until progression or unacceptable toxicities. The primary endpoint was progression-free survival (PFS) rate at 6 months. Forty three patients were enrolled between November 2019 and October 2022. The primary endpoint was met: 6-month PFS rate was 58.8% (90% confidence interval [CI], 45.7%-72.0%). Median PFS and OS were 7.3 months (95% CI, 5.5-11.0 months) and 18.8 months (95% CI, 12.9-26.6 months), respectively. The overall response rate was 20.9% (95% CI, 10.0-36.0%) and disease control rate was 88.4% (95% CI, 74.9-96.1%). The main grade ≥3 adverse events included hypertension (62.8%), neutropenia (55.8%), leukopenia (25.6%), febrile neutropenia (11.6%), fatigue (9.3%), anorexia (9.3%), proteinuria (9.3%), and diarrhea (7.0%). No deaths and no new safety signals with a causal relation to the study treatment were observed. This study suggests that AFL plus FOLFIRI shows a high response rate and a manageable safety profile in Japanese patients with mCRC who failed prior oxaliplatin-based chemotherapy plus an anti-EGFR agent.
