The Pulse of the Pharmaceutical Industry
PRINCETON, N.J., Sept. 22, 2015 /PRNewswire/ — Taiho Oncology, Inc. (U.S.), a subsidiary of Taiho Pharmaceutical Co., Ltd. (Japan), today announced that the U.S. Food and Drug Administration (FDA) approved LONSURF® (trifluridine and tipiracil), formerly known as 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.1
“Patients with metastatic colorectal cancer, whose disease has progressed after treatment with standard therapies, have had limited therapeutic options to treat their disease,” said Eric Benn, Taiho Oncology’s President and Chief Executive Officer. “LONSURF helps address this unmet medical need by providing patients with a new therapeutic option that can help extend their overall survival. As the first FDA approval for Taiho Oncology, LONSURF also represents a major milestone for our company.”
“Metastatic colorectal cancer cells often become resistant to previously effective treatment, underscoring the importance of identifying new therapeutic options for patients with the disease,” said Robert J. Mayer, MD, Faculty Vice President for Academic Affairs at the Dana Farber Cancer Institute, Professor of Medicine at Harvard Medical School, and Principal Investigator of the RECOURSE study. “In a pivotal clinical trial, LONSURF demonstrated that it can extend overall survival, providing patients and their oncologists with a novel oral therapy.”
Pivotal Phase III Study Demonstrates Improvement in Overall Survival (OS)
The FDA approval of LONSURF is based on results from the global Phase III RECOURSE trial in 800 patients who have been previously treated for mCRC.1
The trial met the primary efficacy endpoint of statistically significant improvement in OS compared to placebo (HR = 0.68, CI: 0.58, 0.81, p < 0.001). LONSURF reduced the risk of death by 32 percent when compared to placebo. Median OS was 7.1 months (95 percent CI: 6.5, 7.8) and 5.3 months (95 percent CI: 4.6, 6.0) for LONSURF and placebo, respectively.1
LONSURF caused severe and life-threatening myelosuppression (Grade 3-4) consisting of anemia (18%), neutropenia (38%), thrombocytopenia (5%), and febrile neutropenia (3.8%). Complete blood counts should be obtained prior to and on Day 15 of each cycle of LONSURF and more frequently as clinically indicated. One patient (0.2%) died due to neutropenic infection.1
The most common adverse drug reactions or laboratory abnormalities were anemia, neutropenia, asthenia/fatigue, nausea, thrombocytopenia, decreased appetite, diarrhea, vomiting, abdominal pain, and pyrexia. The most common adverse reactions leading to dose reduction were neutropenia, anemia, febrile neutropenia, fatigue, and diarrhea.1
“Data from the pivotal RECOURSE study demonstrated a significant survival benefit for patients with refractory metastatic colorectal cancer, whose disease had progressed after standard therapies, reducing the risk of death in these patients by 32 percent,” said Fabio Benedetti, MD, Taiho Oncology’s Senior Vice President and Chief Medical Officer. “This significant milestone underscores our longstanding commitment to patients challenged by metastatic colorectal cancer and to bringing new treatment options to them.”
LONSURF was approved in Japan in March 2014 and is indicated to treat unresectable advanced or recurrent colorectal cancer.2
About Metastatic Colorectal Cancer
Colorectal cancer is the third most common type of cancer and is the second leading cause of cancer-related deaths in the U.S.3 In the U.S., there were an estimated 136,830 patients diagnosed with cancer of the colon or rectum in 2014, and in 2012, there were an estimated 1.1 million individuals living with the disease.4,5 Of those, about 27,400 patients will have had their cancer spread to another part of the body.5
LONSURF 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.1
Important Safety Information1
WARNINGS AND PRECAUTIONS
Severe Myelosuppression: In Study 1, LONSURF caused severe and life-threatening myelosuppression (Grade 3-4) consisting of anemia (18%), neutropenia (38%), thrombocytopenia (5%), and febrile neutropenia (3.8%). One patient (0.2%) died due to neutropenic infection. In Study 1, 9.4 percent of LONSURF-treated patients received granulocyte-colony stimulating factors.
Obtain complete blood counts prior to and on Day 15 of each cycle of LONSURF and more frequently as clinically indicated. Withhold LONSURF for febrile neutropenia, Grade 4 neutropenia, or platelets less than 50,000/mm3. Upon recovery, resume LONSURF at a reduced dose.
Embryo-Fetal Toxicity: LONSURF can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with LONSURF.
USE IN SPECIFIC POPULATIONS
Lactation: It is not known whether LONSURF or its metabolites are present in human milk. There are no data to assess the effects of LONSURF or its metabolites on the breastfed infant or the effects on milk production. Because of the potential for serious adverse reactions in breastfeeding infants, advise women not to breastfeed during treatment with LONSURF and for one day following the final dose.
Male Contraception: Advise males with female partners of reproductive potential to use condoms during treatment with LONSURF and for at least 3 months after the final dose.
Geriatric Use: Grade 3 or 4 neutropenia and thrombocytopenia and Grade 3 anemia occurred more commonly in patients 65 years old or older who received LONSURF.
Renal Impairment: Patients with moderate renal impairment may require dose modifications for increased toxicity. No patients with severe renal impairment were enrolled in Study 1.
Hepatic Impairment: Patients with moderate or severe hepatic impairment were not enrolled in Study 1.
Most Common Adverse Drug Reactions in Patients Treated with LONSURF (> or = 5 percent): The most common adverse drug reactions in LONSURF-treated patients vs placebo-treated patients with refractory mCRC, respectively, were: asthenia/fatigue (52% vs 35%), nausea (48% vs 24%), decreased appetite (39% vs 29%), diarrhea (32% vs 12%), vomiting (28% vs 14%), abdominal pain (21% vs 18%), pyrexia (19% vs 14%), stomatitis (8% vs 6%), dysgeusia (7% vs 2%), and alopecia (7% vs 1%).
Additional Important Adverse Drug Reactions: The following occurred more frequently in LONSURF-treated patients compared to placebo: infections (27% vs 15%), and pulmonary emboli (2% vs 0%).
Interstitial lung disease (0.2%), including fatalities, has been reported in clinical studies and clinical practice settings in Asia.
Laboratory Test Abnormalities in Patients Treated with LONSURF: Laboratory test abnormalities in LONSURF-treated patients vs placebo-treated patients with refractory mCRC, respectively, were: anemia (77% vs 33%), neutropenia (67% vs 1%), and thrombocytopenia (42% vs 8%).
