Taiho Pharmaceutical Announces FDA Approval of LONSURF® (trifluridine and tipiracil) for Refractory Metastatic Colorectal Cancer (mCRC) (24/09/2015)

Approval provides patients with new therapeutic option for mCRC that is refractory or intolerant to standard chemotherapies

Taiho Pharmaceutical Co., Ltd. (HQ: Tokyo, President and Representative Director: Masayuki Kobayashi) today announced that the U.S. Food and Drug Administration (FDA) approved LONSURF® (nonproprietary names: trifluridine and tipiracil, IND code:TAS-102) for the treatment of patients with metastatic colorectal cancer (mCRC) who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF biological therapy, and if RAS wild-type, an anti-EGFR therapy.

LONSURF is the first FDA–approved product for the company, and Taiho Oncology Inc., a subsidiary of Taiho Pharmaceutical Co., Ltd., will market LONSURF in the United States.

The FDA approval of LONSURF is based on results from the global Phase III RECOURSE trial that is a pivotal randomized, double blind, placebo controlled trial conducted in 800 patients who have been previously treated for mCRC. The trial met the primary efficacy endpoint of statistically significant improvement in overall survival compared to placebo (HR = 0.68, p < 0.001) and demonstrated a safety profile consistent with that observed in earlier clinical trials.i

About LONSURF
LONSURF is an oral combination anticancer drug of trifluridine (FTD) and tipiracil (TPI). FTD is an antineoplastic thymidine-based 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. LONSURF was approved initially in Japan in March 2014 based on the results of the Phase II clinical trial conducted in Japan, and launched in Japan in May 2014.
