– Approval based on statistically significant and clinically
meaningful improvement in progression-free survival for CABOMETYX versus
sunitinib in CABOSUN trial –
– Triggers $50 million milestone payment to Exelixis under
licensing agreement with Ipsen –
SOUTH SAN FRANCISCO--(BUSINESS WIRE)--May 17, 2018--
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
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.

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.
