Evaluation of antitumor activity of navelbine (vinorelbine ditartrate) against human breast carcinoma xenografts based on its pharmacokinetics in nude mice.


The in vitro antitumor activity of navelbine (NVB, KW-2307), a newly synthesized vinca alkaloid, was compared with that of adriamycin (ADM) against human breast carcinomas inoculated into nude mice at the maximum tolerated dose (MTD) and clinically equivalent dose (CED). The plasma levels of NVB after intravenous injection into nude mice at doses of 1.2 and… (More)
