Irinotecan is an antineoplastic enzyme inhibitor primarily used in the treatment of colorectal cancer. Irinotecan is sold under the brand name Camptosar among others. CAMPTOSAR is a topoisomerase inhibitor indicated for: • First-line therapy in combination with 5-fluorouracil and leucovorin for patients with metastatic carcinoma of the colon or rectum. • Patients with metastatic carcinoma of the colon or rectum whose disease has recurred or progressed following initial fluorouracil-based therapy. Irinotecan is a derivative of camptothecin. Camptothecins interact specifically with the enzyme topoisomerase I, which relieves torsional strain in DNA by inducing reversible single-strand breaks. Irinotecan and its active metabolite SN-38 bind to the topoisomerase I-DNA complex and prevent religation of these single-strand breaks. Current research suggests that the cytotoxicity of irinotecan is due to double-strand DNA damage produced during DNA synthesis when replication enzymes interact with the ternary complex formed by topoisomerase I, DNA, and either irinotecan or SN-38. Mammalian cells cannot efficiently repair these double-strand breaks.

In Vivo Use Guide

Usual Adult Dose for Colorectal Cancer Either as a single agent or in combination with fluorouracil and leucovorin: 125 mg/m2 intravenously over 90 minutes once a week for four doses or as a single agent: 350 mg/m2 intravenously over 90 minutes every three weeks or in combination with fluorouracil and leucovorin: 180 mg/m2 intravenously over 90 minutes every other week for three doses.

Route of Administration: Intravenous

In Vitro Use Guide

The sensitivity to CPT-11 (Irinotecan) alone, of 5 human colon-cancer cell lines, expressed as IC50 values, varied between 2.5 and 6.1uM. The anti-proliferative effectsof the active metabolite SN-38 showed IC50 values between 5.6 and 38 nM, 130 to 570 times lower than those measured for CPT-11 alone. The sensitivity to SN-38 was highest in LS174T and COLO320 cells, intermediate in SW1398 cells and lowest in COLO 205 and WiDr cells.
