FDA approves Lonsurf drug for patients with advanced form of colorectal cancer

In continuation of my update Lonsurf

The U.S. Food and Drug Administration today approved Lonsurf (a pill that combines two drugs, trifluridine and tipiracil) for patients with an advanced form of colorectal cancer who are no longer responding to other therapies.

"The past decade has brought a new understanding around colorectal cancer, in how we can both detect and treat this often devastating disease," said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research. "But there are many patients who still need additional options, and today's approval is a testament to the FDA's commitment to work with companies to develop new drugs in disease areas where unmet needs remain."

Colorectal cancer is the third most common non-skin cancer in men and women in the U.S., according to the National Cancer Institute. While still the second leading cause of cancer-related death in the U.S., over the past 10 years the number of colorectal cancer cases and related deaths have decreased, due in part to screenings, such as colonoscopies.

Taiho Oncology announces acceptance of TAS-102 NDA for review by FDA

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."

FDA Approves Lonsurf (trifluridine/tipiracil) for Adult Patients with Previously Treated Advanced Gastric or Gastroesophageal Junction (GEJ) Adenocarcinoma

In continuation of my update on Lonsurf

Taiho Oncology, Inc.  announced that the United States Food and Drug Administration (FDA) has approved Lonsurf as a treatment for adult patients with metastatic gastric or gastroesophageal junction adenocarcinoma previously treated with at least two prior lines of chemotherapy that included a fluoropyrimidine, a platinum, either a taxane or irinotecan, and if appropriate, HER2/neu-targeted therapy.

“The approval of Lonsurf represents a significant milestone for patients living with advanced gastric or GEJ adenocarcinoma who have limited effective treatment options after standard treatment options have failed,” said Timothy Whitten, President and Chief Executive Officer, Taiho Oncology, Inc. “We thank all the patients and physicians who helped make this possible through their participation in Lonsurf clinical trials.”

The approval for Lonsurf follows an FDA Priority Review designation and is based on data from a global, randomized, Phase III TAGS trial evaluating Lonsurf plus best supportive care (BSC) versus placebo plus BSC in patients with previously treated advanced gastric cancer or GEJ adenocarcinoma following progression or intolerance to previous lines of standard therapy. The trial met its primary and secondary endpoints demonstrating prolonged overall survival (OS) with Lonsurf versus placebo, and a safety profile consistent with prior experience with this drug. Full results from the TAGS trial were presented at the European Society of Medical Oncology (ESMO) 2018 Congress with a simultaneous publication in The Lancet Oncology.1

“Effective treatments for patients with heavily pretreated advanced gastric and GEJ cancer are limited,” said Martin Birkhofer, MD, Senior Vice President and Chief Medical Officer, Taiho Oncology, Inc. “By improving survival, Lonsurf may provide a significant impact on the lives of these patients.”

This approval expands the current indication for Lonsurf in the United States, where it is currently approved for the treatment of patients with metastatic colorectal cancer (mCRC) who have been previously treated with standard chemotherapy, based on results obtained in the RECOURSE trial.
