IRI – irinotecan (Camptosar), a topoisomerase inhibitor, prevents DNA from uncoiling and duplicating.
It is usually given with bevacizumab,[7] unlike FOLFIRINOX for treatment of advanced pancreatic cancer. Also, the doses (Day 1: irinotecan 165 mg/m2 IV, plus oxaliplatin 85 mg/m2 IV; Day 1: leucovorin 400 mg/m2; Days 1–3: fluorouracil 1,600 mg/m2/day × 2 days (total 3,200 mg/m2 over 48 hours) continuous infusion starting on day 1; Day 1: bevacizumab 5 mg/kg IV; repeat cycle every 2 weeks)[1][8][9] are slightly dissimilar to FOLFIRINOX.
Upfront FOLFOXIRI with bevacizumab can be followed by fluoropyrimidine with bevacizumab maintenance.[10]
