European Commission Approves CABOMETYX(TM) (cabozantinib) Tablets for the Treatment of Advanced Renal Cell Carcinoma Following VEGF-Targeted TherapySOUTH SAN FRANCISCO, Calif.--(Healthcare Sales & Marketing Network)--Exelixis, Inc. (EXEL) today announced that the European Commission (EC) has approved CABOMETYX™ (cabozantinib) tablets for the treatment of advanced renal cell carcinoma (RCC) in adults following prior vascular endothelial growth factor (VEGF)-targeted therapy. CABOMETYX was granted accelerated assessment by the European Medicines Agency, and is the first therapy to demonstrate in a phase 3 trial for patients with advanced RCC, robust and clinically meaningful improvements in all three key efficacy parameters — overall survival (OS), progression-free survival (PFS) and objective response rate (ORR). This approval allows for the marketing of CABOMETYX in all 28 member states of the European Union, Norway and Iceland.
EC approval of CABOMETYX triggers a $60 million milestone payment to Exelixis under the licensing agreement with Ipsen for the commercialization and further development of CABOMETYX indications outside of the United States, Canada and Japan. The approval is based on the results of the large, randomized phase 3 METEOR trial.
“The marketing authorization of CABOMETYX by the European Commission to treat patients with advanced renal cell carcinoma reflects the strong efficacy results observed with cabozantinib in the phase 3 METEOR trial, and is an important milestone in our collaboration with Ipsen,” said Michael M. Morrissey, Ph.D., president and chief executive officer of Exelixis. “This marketing authorization helps address an unmet medical need in Europe by providing patients with a new therapy that slows disease progression and prolongs overall survival. We look forward to further examining the use of CABOMETYX in earlier lines of therapy and in other difficult-to-treat cancers.”
About CABOMETYX™ (cabozantinib)
CABOMETYX is the tablet formulation of cabozantinib. CABOMETYX targets include MET, AXL and VEGFR-1, -2 and -3. In preclinical models, cabozantinib has been shown to inhibit the activity of these receptors, which are involved in normal cellular function and pathologic processes such as tumor angiogenesis, invasiveness, metastasis and drug resistance.
CABOMETYX is available in 20 mg, 40 mg or 60 mg doses. The recommended dose is 60 mg orally, once daily.
On April 25, the U.S. FDA approved CABOMETYX tablets for the treatment of patients with advanced renal cell carcinoma who have received prior anti-angiogenic therapy. On September 9, 2016, the European Commission approved CABOMETYX tablets for the treatment of advanced renal cell carcinoma in adults who have received prior vascular endothelial growth factor (VEGF)-targeted therapy in the European Union, Norway and Iceland.
On February 29, 2016, Exelixis and Ipsen jointly announced an exclusive licensing agreement for the commercialization and further development of cabozantinib indications outside of the United States, Canada and Japan.
About the METEOR Phase 3 Pivotal Trial
METEOR was an open-label, event-driven trial of 658 patients with advanced renal cell carcinoma who had failed at least one prior VEGFR TKI therapy. The primary endpoint was PFS in the first 375 patients randomized. Secondary endpoints included OS and objective response rate in all enrolled patients. The trial was conducted at approximately 200 sites in 26 countries, and enrollment was weighted toward Western Europe, North America, and Australia. Patients were randomized 1:1 to receive 60 mg of CABOMETYX daily or 10 mg of everolimus daily and were stratified based on the number of prior VEGFR TKI therapies received and on MSKCC risk criteria. No cross-over was allowed between the study arms.
METEOR met its primary endpoint by significantly improving PFS. Compared with everolimus, CABOMETYX was associated with a 42 percent reduction in the rate of disease progression or death. Median PFS for CABOMETYX was 7.4 months versus 3.8 months for everolimus (HR=0.58, 95% CI 0.45-0.74, P<0.0001). CABOMETYX also significantly improved the objective response rate compared with everolimus, be it through investigator assessment (24% versus 4%, p<0.0001) or through central review (17% versus 3%, p < 0.0001). These data were presented at the European Cancer Congress in September 2015 and published in The New England Journal of Medicine.1
CABOMETYX also demonstrated a statistically significant and clinically meaningful increase in OS in the METEOR trial. Compared with everolimus, CABOMETYX was associated with a 34 percent reduction in the rate of death. Median OS was 21.4 months for patients receiving CABOMETYX versus 16.5 months for those receiving everolimus (HR=0.66, 95% CI 0.53-0.83, P=0.0003).
CABOMETYX benefit in OS was robust and consistent across all pre-specified subgroups. In particular, benefit was observed regardless of risk category, location and extent of tumor metastases, and tumor MET expression level. These results were presented on June 5, 2016 at the ASCO Annual Meeting and concurrently published in The Lancet Oncology.2
At the time of the analysis, the median duration of treatment in the trial was 8.3 months with CABOMETYX versus 4.4 months with everolimus. The most frequent adverse events regardless of causality were diarrhea, fatigue, decreased appetite and hypertension for CABOMETYX and fatigue, anemia, decreased appetite and cough for everolimus. Dose reductions occurred for 62 percent and 25 percent of patients, respectively. Discontinuation rate due to an adverse event not related to disease progression was 12 percent with CABOMETYX and 11 percent with everolimus.
About Advanced Renal Cell Carcinoma
Renal cell carcinoma (RCC) represents 2-3 percent of all cancers3, with the highest incidence occurring in Western countries. Generally, during the last two decades until recently, there has been an annual increase of about 2 percent in incidence both worldwide and in Europe, though in Denmark and Sweden a continuing decrease has been observed.4 In 2012, there were approximately 84,400 new cases of RCC and 34,700 kidney cancer related deaths within the European Union.5 In Europe, overall mortality rates for RCC have increased up until the early 1990s, with rates generally stabilizing or declining thereafter.6 There has been a decrease in mortality since the 1980s in Scandinavian countries and since the early 1990s in France, Germany, Austria, the Netherlands, and Italy. However, in some European countries (Croatia, Estonia, Greece, Ireland, Slovakia), mortality rates still show an upward trend with increasing rates. 6
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.7,8 These proteins promote tumor angiogenesis (blood vessel growth), growth, invasiveness and metastasis.9-12 MET and AXL may provide escape pathways that drive resistance to VEGFR inhibitors.8,9
U.S. Important Safety Information
Hemorrhage: Severe hemorrhage occurred with CABOMETYX. The incidence of Grade =3 hemorrhagic events was 2.1% in CABOMETYX-treated patients and 1.6% in everolimus-treated patients. Fatal hemorrhages also occurred in the cabozantinib clinical program. Do not administer CABOMETYX to patients that have or are at risk for severe hemorrhage.
Gastrointestinal (GI) Perforations and Fistulas: Fistulas were reported in 1.2% (including 0.6% anal fistula) of CABOMETYX-treated patients and 0% of everolimus-treated patients. GI perforations were reported in 0.9% of CABOMETYX-treated patients and 0.6% of everolimus-treated patients. Fatal perforations occurred in the cabozantinib clinical program. Monitor patients for symptoms of fistulas and perforations. Discontinue CABOMETYX in patients who experience a fistula that cannot be appropriately managed or a GI perforation.
