Exelixis’ Partner Ipsen Announces Health Canada’s Approval of CABOMETYX® (cabozantinib) Tablets for the Treatment of Adults with Previously Treated Advanced Renal Cell Carcinoma
ALAMEDA, Calif.--(BUSINESS WIRE)--Sep 19, 2018--Exelixis, Inc. (NASDAQ:EXEL) today announced that its partner Ipsen Biopharmaceuticals Canada Inc. received approval from Health Canada of CABOMETYX ® (cabozantinib) tablets for the treatment of adults with advanced renal cell carcinoma (RCC) who have received prior vascular endothelial growth factor (VEGF) targeted therapy. Health Canada granted CABOMETYX priority review status, which provided an accelerated review of Ipsen’s new drug submission.
“The approval of CABOMETYX in Canada helps address a significant unmet need for patients with advanced kidney cancer whose disease has progressed on first-line therapy and who have limited treatments available,” said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. “We are glad to be partnering with Ipsen to bring this much needed treatment option to these patients and look forward to our continued collaboration.”
The Health Canada approval was based on results of the phase 3 pivotal METEOR trial in which CABOMETYX provided a statistically significant and clinically meaningful improvement in overall survival, progression-free survival and objective response rate as compared with everolimus in patients with advanced RCC who have received prior anti-angiogenic therapy.
Under the terms of the Collaboration Agreement with Ipsen, Exelixis will receive a milestone payment of $5 million for the Health Canada approval. The payment will be made by Ipsen within the next 70 days.

About Advanced Renal Cell Carcinoma
The American Cancer Society’s 2018 statistics cite kidney cancer as among the top ten most commonly diagnosed forms of cancer among both men and women in the U.S. 1 The Canadian Cancer Society estimates that kidney cancer is among the top ten most common forms of kidney cancer in Canada, with approximately 6,600 new cases diagnosed in 2017. 2 Clear cell RCC is the most common type of kidney cancer in adults. 3 If detected in its early stages, the five-year survival rate for RCC is high; for patients with advanced or late-stage metastatic RCC, however, the five-year survival rate is only 12 percent, with no identified cure for the disease. 4 Approximately 30,000 patients in the U.S. and 68,000 globally require treatment, and an estimated 14,000 patients in the U.S. each year are in need of a first-line treatment for advanced kidney cancer. 4
The majority of clear cell RCC tumors have lower than normal levels of a protein called von Hippel-Lindau, which leads to higher levels of MET, AXL and VEGF. 5,6 These proteins promote tumor angiogenesis (blood vessel growth), growth, invasiveness and metastasis. 7,8,9,10 MET and AXL may provide escape pathways that drive resistance to VEGF receptor inhibitors. 6,7
About the Exelixis and Ipsen Collaboration
In 2016, Exelixis granted Ipsen exclusive rights for the commercialization and further clinical development of cabozantinib outside of the United States and Japan. Under the terms of the Collaboration Agreement with Ipsen, Exelixis is entitled to receive a tiered royalty of 22 percent to 26 percent of annual net sales.
About CABOMETYX ® (cabozantinib)
CABOMETYX tablets are approved in the United States for the treatment of patients with advanced RCC. CABOMETYX tablets are also approved in: the European Union, Norway, Iceland, Australia, Switzerland and South Korea for the treatment of advanced RCC in adults who have received prior VEGF-targeted therapy; in the European Union for previously untreated intermediate- or poor-risk advanced RCC; and in Canada for adult patients with advanced RCC who have received prior VEGF targeted therapy. In March 2017, the FDA granted orphan drug designation to cabozantinib for the treatment of advanced HCC. On March 28, 2018, Ipsen announced that the European Medicines Agency validated its application for a new indication for cabozantinib as a treatment for previously treated advanced HCC in the European Union. In 2017, Exelixis granted exclusive rights to Takeda Pharmaceutical Company Limited for the commercialization and further clinical development of cabozantinib for all future indications in Japan.
U.S. Important Safety InformationHemorrhage: Severe and fatal hemorrhages have occurred with CABOMETYX. In two RCC studies, the incidence of Grade ≥ 3 hemorrhagic events was 3% in CABOMETYX-treated patients. Do not administer CABOMETYX to patients that have or are at risk for severe hemorrhage. Gastrointestinal (GI) Perforations and Fistulas: In RCC studies, fistulas were reported in 1% of CABOMETYX-treated patients. Fatal perforations occurred in patients treated with CABOMETYX. In RCC studies, gastrointestinal (GI) perforations were reported in 1% of CABOMETYX-treated patients. Monitor patients for symptoms of fistulas and perforations, including abscess and sepsis. Discontinue CABOMETYX in patients who experience a fistula which cannot be appropriately managed or a GI perforation. Thrombotic Events: CABOMETYX treatment results in an increased incidence of thrombotic events. In RCC studies, venous thromboembolism occurred in 9% (including 5% pulmonary embolism) and arterial thromboembolism occurred in 1% of CABOMETYX-treated patients. Fatal thrombotic events occurred in the cabozantinib clinical program. Discontinue CABOMETYX in patients who develop an acute myocardial infarction or any other arterial thromboembolic complication. Hypertension and Hypertensive Crisis: CABOMETYX treatment results in an increased incidence of treatment-emergent hypertension, including hypertensive crisis. In RCC studies, hypertension was reported in 44% (18% Grade ≥ 3) of CABOMETYX-treated patients. Monitor blood pressure prior to initiation and regularly during CABOMETYX treatment. Withhold CABOMETYX for hypertension that is not adequately controlled with medical management; when controlled, resume CABOMETYX at a reduced dose. Discontinue CABOMETYX for severe hypertension that cannot be controlled with anti-hypertensive therapy. Discontinue CABOMETYX if there is evidence of hypertensive crisis or severe hypertension despite optimal medical management. Diarrhea: In RCC studies, diarrhea occurred in 74% of patients treated with CABOMETYX. Grade 3 diarrhea occurred in 11% of patients treated with CABOMETYX. Withhold CABOMETYX in patients who develop intolerable Grade 2 diarrhea or Grade 3-4 diarrhea that cannot be managed with standard antidiarrheal treatments until improvement to Grade 1; resume CABOMETYX at a reduced dose. Palmar-Plantar Erythrodysesthesia (PPE): In RCC studies, palmar-plantar erythrodysesthesia (PPE) occurred in 42% of patients treated with CABOMETYX. Grade 3 PPE occurred in 8% of patients treated with CABOMETYX. Withhold CABOMETYX in patients who develop intolerable Grade 2 PPE or Grade 3 PPE until improvement to Grade 1; resume CABOMETYX at a reduced dose. Reversible Posterior Leukoencephalopathy Syndrome (RPLS), a syndrome of subcortical vasogenic edema diagnosed by characteristic finding on MRI, occurred in the cabozantinib clinical program. Perform an evaluation for RPLS in any patient presenting with seizures, headache, visual disturbances, confusion or altered mental function. Discontinue CABOMETYX in patients who develop RPLS. Embryo-fetal Toxicity may be associated with CABOMETYX. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during CABOMETYX treatment and for 4 months after the last dose. Adverse Reactions: The most commonly reported (≥25%) adverse reactions are: diarrhea, fatigue, nausea, decreased appetite, hypertension, PPE, weight decreased, vomiting, dysgeusia, and stomatitis. Strong CYP3A4 Inhibitors: If concomitant use with strong CYP3A4 inhibitors cannot be avoided, reduce the CABOMETYX dosage. Strong CYP3A4 Inducers: If concomitant use with strong CYP3A4 inducers cannot be avoided, increase the CABOMETYX dosage. Lactation: Advise women not to breastfeed while taking CABOMETYX and for 4 months after the final dose. Hepatic Impairment: In patients with mild to moderate hepatic impairment, reduce the CABOMETYX dosage. CABOMETYX is not recommended for use in patients with severe hepatic impairment.
