Exelixis Announces U.S. FDA Grants Priority Review for CABOMETYX® (Cabozantinib) as a Treatment for Previously Untreated Advanced Renal Cell Carcinoma
SOUTH SAN FRANCISCO, Calif.
– FDA assigns Prescription Drug User Fee Act action date of February 15, 2018 –
Exelixis, Inc. (NASDAQ:EXEL) today announced that the U.S. Food and Drug Administration (FDA) has determined the company’s supplemental New Drug Application (sNDA) for CABOMETYX® (cabozantinib) for patients with previously untreated advanced renal cell carcinoma (RCC) to be sufficiently complete to permit a substantive review. The FDA granted Priority Review of the filing and assigned a Prescription Drug User Fee Act (PDUFA) action date of February 15, 2018.
“The acceptance of the sNDA filing with a Priority Review is an important regulatory milestone for CABOMETYX and for our mission to improve treatment outcomes for patients with cancer,” said Gisela Schwab, M.D., President, Product Development and Medical Affairs and Chief Medical Officer, Exelixis. “We look forward to working with the FDA as they review the application in our effort to offer CABOMETYX to patients with previously untreated metastatic RCC who are in need of new treatment options.”
The sNDA is based on data from CABOSUN, a randomized phase 2 trial conducted by The Alliance for Clinical Trials in Oncology as part of Exelixis’ collaboration with the National Cancer Institute’s Cancer Therapy Evaluation Program (NCI-CTEP).
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.
CABOMETYX was previously approved by the FDA on April 25, 2016 for the treatment of patients with advanced RCC who have received prior anti-angiogenic therapy. The approval was based on results from the phase 3 METEOR trial, which demonstrated that CABOMETYX provided a statistically significant and clinically meaningful improvement in overall survival, progression-free survival (PFS), and objective response rate as compared with everolimus in this patient population.

About the CABOSUN Study
On May 23, 2016, Exelixis announced that CABOSUN 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. CABOSUN was conducted by The Alliance for Clinical Trials in Oncology as part of Exelixis’ collaboration with the NCI-CTEP. 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 and objective response rate. 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 2017 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.5 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.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 VEGF receptor inhibitors.7,8
About CABOMETYX® (cabozantinib)
CABOMETYX is the tablet formulation of cabozantinib. Its 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, 2016, the FDA approved CABOMETYX tablets for the treatment of patients with advanced RCC who have received prior anti-angiogenic therapy. In February of 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. This agreement was amended in December of 2016 to include commercialization rights for Ipsen in Canada. On September 9, 2016, the European Commission approved CABOMETYX tablets for the treatment of advanced RCC in adults who have received prior vascular endothelial growth factor (VEGF)-targeted therapy in the European Union, Norway and Iceland. Ipsen also submitted to European Medicines Agency (EMA) the regulatory dossier for cabozantinib as a treatment for first-line advanced RCC in the European Union on August 28, 2017; on September 8, 2017, Ipsen announced that the EMA validated the application.
On January 30, 2017, Exelixis and Takeda Pharmaceutical Company Limited announced an exclusive licensing agreement for the commercialization and further clinical development of cabozantinib for all future indications in Japan, including RCC.
CABOMETYX is not indicated for the treatment of previously untreated advanced RCC.
