Overview

FOLFIRI + regorafenib is a combination therapy used primarily in the treatment of metastatic colorectal cancer, especially in patients who have progressed after standard first-line therapies. FOLFIRI is a chemotherapy regimen consisting of folinic acid (leucovorin), fluorouracil (5-FU), and irinotecan. Folinic acid enhances the effectiveness of 5-FU, which acts as an antimetabolite to disrupt DNA synthesis, while irinotecan inhibits topoisomerase I, blocking DNA replication and leading to cancer cell death[6][8][10]. Regorafenib is an oral multikinase inhibitor that targets multiple protein kinases involved in tumor angiogenesis, oncogenesis, and the tumor microenvironment. It inhibits kinases such as VEGFR1-3, PDGFR-β, FGFR1/2/3/4, KIT, RET, RAF-1/BRAF (including mutant BRAF), TIE2 and others[4][7]. The combination aims to leverage both cytotoxic chemotherapy and targeted inhibition of key signaling pathways for improved disease control. Clinical studies suggest this regimen can provide modest improvements in progression-free survival compared to FOLFIRI alone but may be associated with increased toxicity[3][4][5].
