Taiho Pharmaceutical Announces TAS-102 (brand name in Japan: "Lonsurf®") New Drug Application for Refractory Metastatic Colorectal Cancer Accepted for Review by FDA

Taiho Pharmaceutical Co., Ltd. (HQ: Tokyo, President and Representative Director: Masayuki Kobayashi) today announced that the U.S. Food and Drug Administration (FDA) has accepted the Company's submission of a New Drug Application (NDA) for TAS-102 (nonproprietary names: trifluridine and tipiracil hydrochloride, brand name in Japan: "Lonsurf® combination tablet T15, T20"). TAS-102 is an oral combination investigational anticancer drug for the treatment of refractory metastatic colorectal cancer (mCRC). The PDUFA goal date is December 19, 2015.

Results from the Phase III RECOURSE trial of TAS-102 in 800 mCRC patients, whose disease had progressed after or who were intolerant to standard therapies, form the foundation for the NDA. The TAS-102 RECOURSE trial met the primary efficacy endpoint of statistically significant improvement in overall survival versus placebo (HR = 0.68, p < 0.0001) and demonstrated a safety profile consistent with that observed in earlier clinical trials.

About TAS-102

TAS-102 is an oral combination investigational 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 2014 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 2014 under the brand name "Lonsurf® combination tablet T15, T20".
