Exelixis’ Partner Ipsen Announces European Commission Approval of CABOMETYX® (Cabozantinib) for Previously Untreated Intermediate- or Poor-Risk Advanced Renal Cell Carcinoma
May. 17, 2018
SOUTH SAN FRANCISCO--(BUSINESS WIRE)--May 17, 2018--Exelixis, Inc. (Nasdaq:EXEL) today announced that its partner Ipsen received approval from the European Commission (EC) for CABOMETYX ® (cabozantinib) 20 mg, 40 mg and 60 mg for the first-line treatment of adults with intermediate- or poor-risk advanced renal cell carcinoma (RCC) in the European Union.
“The expanded marketing authorization of CABOMETYX to include previously untreated patients in Europe with intermediate- or poor-risk advanced kidney cancer is an exciting milestone for a patient population in need of more treatment options,” said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. “We look forward to our continued collaboration with our partners Ipsen and Takeda to bring new options to more patients with difficult-to-treat cancers in Europe and around the world.”
Under the terms of the Collaboration and License Agreement with Ipsen, Exelixis will receive a milestone payment of $50 million for the EC approval, of which approximately $46 million was recognized as collaboration revenue in the first quarter of 2018. The payment will be made by Ipsen within the next 70 days.
CABOMETYX was approved in the European Union in September 2016 for the treatment of advanced RCC in adults following prior vascular endothelial growth factor (VEGF)-targeted therapy. The expanded EC approval to include first-line treatment is based on results of the CABOSUN trial, which met its primary endpoint of improved progression-free survival (PFS) compared with sunitinib in patients with previously untreated advanced RCC determined to be intermediate- or poor-risk by the International Metastatic RCC Database Consortium (IMDC) criteria. In December 2017, the U.S. Food and Drug Administration (FDA) approved CABOMETYX for the expanded indication of patients with advanced RCC based on the results from the CABOSUN trial.

About the CABOSUN Study
On May 23, 2016, Exelixis announced that the phase 2 CABOSUN study met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in PFS compared with sunitinib in patients with advanced intermediate- or poor-risk RCC as determined by investigator assessment. The CABOSUN study was conducted by The Alliance for Clinical Trials in Oncology and was sponsored by the National Cancer Institute-Cancer Therapy Evaluation Program (NCI-CTEP) under the Cooperative Research and Development Agreement with Exelixis for the development of cabozantinib. These results were first presented by Dr. Toni Choueiri at the European Society for Medical Oncology (ESMO) 2016 Congress, and published in the Journal of Clinical Oncology (Choueiri, JCO, 2016). 1 In June 2017, a blinded independent radiology review committee (IRC) confirmed that cabozantinib provided a clinically meaningful and statistically significant improvement in the primary efficacy endpoint of investigator-assessed PFS. Results from the IRC review were presented by Dr. Toni Choueiri at the ESMO 2017 Congress.
CABOSUN was a randomized, open-label, active-controlled phase 2 trial that enrolled 157 patients with advanced RCC determined to be intermediate- or poor-risk by the IMDC criteria. Patients were randomized 1:1 to receive cabozantinib (60 mg once daily) or sunitinib (50 mg once daily, 4 weeks on followed by 2 weeks off). The primary endpoint was PFS. Secondary endpoints included overall survival, objective response rate and safety. Eligible patients were required to have locally advanced or metastatic clear-cell RCC, ECOG performance status 0-2 and had to be intermediate- or poor-risk per the IMDC criteria (Heng, JCO, 2009). 2 Prior systemic treatment for RCC was not permitted.
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. 3 Clear cell RCC is the most common type of kidney cancer in adults. 4 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. 3 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. 5
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. 6,7 These proteins promote tumor angiogenesis (blood vessel growth), growth, invasiveness and metastasis. 8,9,10,11 MET and AXL may provide escape pathways that drive resistance to VEGF receptor inhibitors. 7,8
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, and in the European Union for previously untreated intermediate- or poor-risk advanced RCC. Regulatory applications were recently submitted for CABOMETYX for additional advanced hepatocellular carcinoma (HCC) indications: on March 15, 2018, Exelixis announced the completed submission of a supplemental New Drug Application to the U.S. FDA for CABOMETYX for previously treated patients with 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 hepatocellular carcinoma in the European Union.
In 2016, Exelixis granted Ipsen exclusive rights for the commercialization and further clinical development of cabozantinib outside of the United States and Japan. 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, including RCC.

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.
