描述 | Trifluridine have been widely used for the treatment of multiple neoplasms. But trifluridine is rapidly degraded to an inactive metabolite by thymidine phosphorylase making its poor bioavailability. Tipiracil HCl, a potent and specific chemical inhibitor of thymidine phosphorylase, creates an opportunity to improve the PK properties of trifluridine. Trifluridine/tipiracil (TAS-102) is a new orally active antineoplastic agent comprised of trifluridine and tipiracil in a molar ratio of 1:0.5. Compared with trifluridine alone, the coadministration of oral trifluridine and tipiracil in mice and monkeys led to an increased bioavailability of trifluridine and a marked increase in the trifluridine area under the concentration–time curve (AUC) and maximum observed plasma concentration (Cmax). The global phase 3 RECOURSE trial showed that, compared with a placebo control, trifluridine/tipiracil increased overall survival in patients with refractory metastatic colorectal cancer by 1.8 months[3]. |
