Exatecan (DX-8951f), a new hexacyclic camptothecin analogue, is a second-generation topoisomerase inhibitor that prevents rapidly dividing cells from replicating by interrupting DNA transcription, ultimately leading to cell death. Preclinical studies showed exatecan to have broad-spectrum antitumor efficacy. Exatecan is in phase III clinical trials for the treatment of pancreas cancer. However, there is no recent report of this research. The compound was co-developed by Daiichi Pharmaceutical (now Daiichi Sankyo) and Yakult Honsha.

Sample Use Guides

In Vivo Use Guide

Fifty-seven patients with bidimensionally measurable ovarian cancer, previously exposed to platinum and taxanes, whose disease had relapsed within 6 months of platinum-containing chemotherapy were randomised to one of two intravenous schedules of exatecan mesylate; 0.3 mg/m(2) daily for 5 days every 3 weeks (Arm A) or 2.1 mg/m(2) weekly for 3 weeks out of 4 (Arm B).

Route of Administration: Intravenous

In Vitro Use Guide

Exatecan had superior antitumor efficacy compared to topotecan and irinotecan against all human malignancies tested, with mean IC50 values of 30.8, 48.2, 43.6 and 70.6 ng/ml, respectively, against esophageal, gastric, colorectal and breast cancer lines.
