FDA Accepts Supplemental New Drug Application for LONSURF® (trifluridine/tipiracil) for the Treatment of Metastatic Gastric/Gastroesophageal Junction (GEJ) Adenocarcinoma; Grants Priority Review

PRINCETON, N.J., October 25, 2018 – Taiho Oncology, Inc. today announced that the United States Food and Drug Administration (FDA) has accepted and granted priority review for the supplemental New Drug Application (sNDA) for LONSURF® (trifluridine/tipiracil, TAS-102) as a treatment for patients with previously treated, advanced or metastatic gastric adenocarcinoma, including cancer of the gastroesophageal junction. The FDA has provided an anticipated Prescription Drug User Fee Act (PDUFA) action date of February 24, 2019.

“We look forward to working with the FDA as they consider the application for LONSURF under priority review,” said Martin Birkhofer, MD, senior vice president and Chief Medical Officer, Taiho Oncology, Inc.

The sNDA is based on data from the global, randomized, double blind pivotal Phase III (TAGS) trial evaluating LONSURF versus placebo and best supportive care in patients with heavily pretreated metastatic gastric/gastroesophageal junction (GEJ) adenocarcinoma that progressed or were intolerant to previous lines of therapy. The trial met its primary endpoint of prolonged overall survival (OS) and secondary endpoint measures of progression-free survival (PFS), as well as continuing to demonstrate LONSURF’s consistent safety and tolerability profile. Full results from this study were recently presented at the European Society of Medical Oncology (ESMO) 2018 Congress in Munich and published simultaneously in The Lancet Oncology.

LONSURF, in the United States, is indicated for the treatment of patients with metastatic colorectal cancer 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 [US prescribing information]; Princeton, NJ: Taiho Oncology, Inc.; 2017. 2017.

About TAGS
TAGS (TAS-102 Gastric Study) is a Taiho-sponsored pivotal Phase III, multinational, randomized, double-blind study evaluating trifluridine/tipiracil, also known as TAS-102, plus best supportive care (BSC) versus placebo plus BSC in patients with metastatic gastric cancer, including gastroesophageal junction cancer, refractory to standard treatments. The primary endpoint in the TAGS trial is overall survival (OS), and the main secondary endpoint measures include progression-free survival (PFS), and safety and tolerability, as well as quality of life.

TAGS enrolled 507 adult patients with metastatic gastric cancer who had previously received at least two prior regimens for advanced disease. The study was conducted in Japan, the United States, the European Union, Russia, Belarus, Israel, and Turkey.

About Metastatic Gastric Cancer
Gastric cancer, also known as stomach cancer, is a disease in which malignant cells form in the lining of the stomach. It is the fifth most common cancer worldwide and the third most common cause of cancer-related death (after lung and liver cancer), with an estimated 723,000 deaths annually.2  Approximately 50 percent of patients with gastric cancer have advanced disease at the time of diagnosis.3

Standard chemotherapy regimens for advanced gastric cancer include fluoropyrimidines, platinum derivatives, and taxanes (with ramucirumab), or irinotecan. The addition of trastuzumab to chemotherapy is standard of care for patients with HER2-neu-positive advanced gastric cancer. However, after failure of first- and second-line therapies, standard third-line treatments are limited.

About Gastroesophageal Junction Cancer

Gastroesophageal junction cancer is a type of cancer that begins in cells located near the GE junction, the area where the esophagus connects to the stomach.4 It remains a significant clinical problem that is increasing in incidence, and is associated with a poor prognosis. The majority of patients present with advanced disease, and less than 50 percent undergo curative treatment.5 

About LONSURF

LONSURF (trifluridine/tipiracil) is an oral anticancer drug, which utilizes the combination of trifluridine (FTD) and tipiracil (TPI), whose dual mechanism of action is designed to maintain clinical activity and differs from conventional fluoropyrimidines. FTD is an antineoplastic nucleoside analogue, which is incorporated directly into the 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.

In Japan, Taiho Pharmaceutical has been marketing LONSURF for the the treatment of unresectable advanced or recurrent colorectal cancer since 2014. In the United States, beginning in 2015, Taiho Oncology, Inc., a U.S. subsidiary of Taiho Pharmaceutical, began marketing the drug for the treatment of patients with 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. In June 2015, Taiho Pharmaceutical and Servier entered into an exclusive license agreement for the co-development and commercialization of LONSURF in Europe and other countries outside of the United States, Canada, Mexico and Asia. In parts of Asia outside of Japan, Taiho Pharmaceutical’s business partner TYY Biopharm launched LONSURF in Taiwan in July 2018, and Jeil Pharmaceutical is preparing to bring the drug to market in South Korea.

As of August 2018, LONSURF has been approved as a treatment for advanced mCRC in 54 countries and regions worldwide.

Indications and Use1
LONSURF is a combination of trifluridine, a nucleoside metabolic inhibitor, and tipiracil, a thymidine phosphorylase inhibitor, indicated for the treatment of patients with metastatic colorectal cancer 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.

Important Safety Information1

LONSURF may cause serious side effects, including:

  • Low blood counts. Low blood counts are common with LONSURF and can sometimes be severe and life‑threatening. LONSURF can cause a decrease in your white blood cells, red blood cells, and platelets. Low white blood cells can make you more likely to get serious infections that could lead to death. Your healthcare provider should do blood tests before you receive LONSURF, at day 15 during treatment with LONSURF, and as needed to check your blood cell counts. Your healthcare provider may lower your dose of LONSURF or stop LONSURF if you have low white blood cell or platelet counts

Tell your healthcare provider right away if you get any of the following signs and symptoms of infection during treatment with LONSURF: fever, chills, or body aches.

Before taking LONSURF, tell your healthcare provider about all of your medical conditions, including if you:

  • Have kidney or liver problems
  • Are pregnant or plan to become pregnant. LONSURF can harm your unborn baby
    • Females who can become pregnant should use effective birth control during treatment with LONSURF. Tell your healthcare provider immediately if you become pregnant
    • Males, while on treatment and for 3 months after your last dose of LONSURF, you should use a condom during sex with female partners who are able to become pregnant. Tell your healthcare provider right away if your partner becomes pregnant while you are taking LONSURF
  • Are breast‑feeding or plan to breast‑feed. It is not known if LONSURF passes into your breast milk. Do not breast‑feed during treatment with LONSURF and for 1 day after your last dose of LONSURF

Tell your healthcare provider about all the prescription and over‑the‑counter medicines, vitamins, and herbal supplements you take.

The most common side effects with LONSURF include tiredness, nausea, decreased appetite, diarrhea, vomiting, abdominal pain, and fever.

Tell your doctor if you have nausea, vomiting, or diarrhea that is severe or that does not go away.

These are not all of the possible side effects of LONSURF. For more information, ask your healthcare provider. Call your doctor for medical advice about side effects.
