Taiho Pharmaceutical Receives FDA Fast Track Designation for TAS-102 as a Potential Treatment for Refractory Metastatic Colorectal Cancer – Taiho Initiates Rolling NDA Submission for TAS-102 – (21/10/2014)

Taiho Pharmaceutical Co., Ltd. (HQ: Tokyo, President and Representative Director: Masayuki Kobayashi) announced that the U.S. Food and Drug Administration (FDA) granted Fast Track designation for TAS-102 (nonproprietary names: trifluridine and tipiracil hydrochloride, brand name in Japan ''Lonsurf® combination tablet T15, T20''), an oral combination anticancer drug under investigation for the treatment of refractory metastatic colorectal cancer (mCRC), and that the Company has initiated a rolling NDA submission to the FDA.

The FDA established the Fast Track designation process to facilitate the development and expedite the review of new drugs that are intended to treat serious or life-threatening conditions, and that demonstrate the potential to address unmet medical needs. Fast Track designated drugs are afforded a rolling review of their New Drug Application (NDA) filing by the FDA.

The results from the Phase III RECOURSE trial of TAS-102 in 800 patients affected with mCRC, whose disease had progressed after or who were intolerant to standard therapies, are the foundation for Taiho's NDA submission to the FDA. Taiho expects to complete its submission by the end of this year.

About TAS-102
TAS-102 is an oral combination anticancer drug of trifluridine (FTD) and tipiracil hydrochloride (TPI). FTD is an antineoplastic nucleoside analog, which is incorporated directly into DNA, thereby interfering with the function of DNA. The blood concentration of FTD is maintained via TPI, which is an inhibitor of the FTD-degrading enzyme, thymidine phosphorylase. TAS-102 was approved initially in Japan in March this year for the indications of ''unresectable advanced or recurrent colorectal cancer (only if refractory to standard therapies),'' based on the results of the Phase II clinical trial conducted in Japan, and launched in Japan in May under the brand name ''Lonsurf® combination tablet T15, T20''.
