Taiho Oncology, Inc., a subsidiary of Taiho Pharmaceutical Co., Ltd. (Japan), today announced the New Drug Application (NDA) for TAS-102 (nonproprietary names: trifluridine and tipiracil hydrochloride), has been accepted for review by the U.S. Food and Drug Administration (FDA). TAS-102 is an oral combination investigational anticancer drug for the treatment of refractory metastatic colorectal cancer (mCRC).
TAS-102 is an investigational drug candidate for metastatic colorectal cancer. It is a combination of two active pharmaceutical ingredients: trifluridine, (see left structure)
a nucleoside analog (see right structure), and tipiracil hydrochloride, a thymidine phosphorylase inhibitor. Tipiracil hydrochloride prevents rapid metabolism of trifluiridine, increasing the bioavailability of trifluiridine.
"The FDA's filing of the TAS-102 NDA represents a significant milestone for our company and underscores the need for new treatment options for patients with refractory metastatic colorectal cancer," said Eric Benn, Taiho Oncology's president and chief executive officer. "Today, we are one step closer to our ultimate goal of gaining regulatory approval for TAS-102 and making it available to patients in the USA with this serious medical condition. We look forward to working closely with the FDA during the NDA review."
