Exelixis’ Partner Ipsen Receives European Commission Approval for CABOMETYX® (cabozantinib) Tablets for the Treatment of Hepatocellular Carcinoma in Adults Previously Treated with Sorafenib
ALAMEDA, Calif.--(BUSINESS WIRE)--Nov 15, 2018--Exelixis, Inc. (Nasdaq: EXEL) today announced that its partner Ipsen received approval from the European Commission (EC) for CABOMETYX ® (cabozantinib) tablets as a monotherapy for hepatocellular carcinoma (HCC) in adults who have previously been treated with sorafenib. This approval allows for the marketing of CABOMETYX in this indication in all 28 member states of the European Union, Norway and Iceland.
“The approval of CABOMETYX in the Europe Union is a very important milestone for our partner Ipsen and marks significant progress for people living with liver cancer, which is the second-leading cause of cancer death worldwide,” said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. “This patient community is in dire need of new options to treat this aggressive disease, and we are excited to work with Ipsen to make this treatment available to patients in the European Union and other countries worldwide.”
Under the terms of the Collaboration Agreement with Ipsen, Exelixis will receive a milestone payment of $40 million for the approval of the second-line treatment of HCC. This milestone will be paid by Ipsen within the next 70 days.
“Today’s European Commission approval of CABOMETYX provides a much-needed new option for HCC patients. Until now, physicians in Europe had only one approved therapy for the second-line treatment of this aggressive and difficult-to-treat cancer. We are proud to offer CABOMETYX as an innovative treatment that has been shown to extend survival in previously treated patients with HCC,” said Harout Semerjian, Chief Commercial Officer of Ipsen. “This new indication reinforces Ipsen’s commitment to improving patients’ lives through the expansion of the clinical benefit of CABOMETYX in the treatment of solid tumors.”
The EC approval is based on results from the CELESTIAL trial of CABOMETYX in patients with advanced HCC who received prior sorafenib. In this phase 3 pivotal trial, CABOMETYX demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) versus placebo. CABOMETYX is also approved in the European Union for the treatment of advanced renal cell carcinoma (RCC) in adults who have received prior VEGF-targeted therapy and for previously untreated intermediate- or poor-risk advanced RCC.
On May 29, 2018, Exelixis announced that the U.S. Food and Drug Administration (FDA) accepted for filing the supplemental New Drug Application (sNDA) for CABOMETYX for previously treated advanced HCC and assigned a Prescription Drug User Fee Act action date of January 14, 2019. An sNDA is an application to the FDA that, if approved, will allow a drug sponsor to make changes to a previously approved product label, including modifications to the indication.
About the CELESTIAL Study
CELESTIAL is a randomized, double-blind, placebo-controlled study of cabozantinib in patients with advanced HCC conducted at more than 100 sites globally in 19 countries. The trial was designed to enroll 760 patients with advanced HCC who received prior sorafenib and may have received up to two prior systemic cancer therapies for HCC and had adequate liver function. Enrollment of the trial was completed in September 2017. Patients were randomized 2:1 to receive 60 mg of cabozantinib once daily or placebo and were stratified based on etiology of the disease (hepatitis C, hepatitis B or other), geographic region (Asia versus other regions) and presence of extrahepatic spread and/or macrovascular invasion (yes or no). No cross-over was allowed between the study arms during the blinded treatment phase of the trial. The primary endpoint for the trial is OS, and secondary endpoints include objective response rate and PFS. Exploratory endpoints include patient-reported outcomes, biomarkers and safety.
In October 2017, Exelixis announced that the independent data monitoring committee for the CELESTIAL study recommended that the trial be stopped for efficacy following review at the second planned interim analysis, with cabozantinib providing a statistically significant and clinically meaningful improvement in OS compared with placebo in patients with previously treated advanced HCC. The data, originally presented at the 2018 American Society of Clinical Oncology’s Gastrointestinal Cancers Symposium (ASCO-GI) in January 2018, were published in The New England Journal of Medicine in July 2018. 1
Liver cancer is the second-leading cause of cancer death worldwide, accounting for more than 700,000 deaths and 800,000 new cases each year. 2 In the U.S., the incidence of liver cancer has more than tripled since 1980. 3 HCC is the most common form of liver cancer, making up about three-fourths of the estimated nearly 42,000 new cases in the U.S. in 2018. 3 HCC is the fastest-rising cause of cancer-related death in U.S. 4 Without treatment, patients with advanced HCC usually survive less than 6 months. 5

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.
