– EC approval triggers $40 million milestone payment to Exelixis
under Collaboration Agreement with Ipsen –
– Exelixis’ supplemental New Drug Application for CABOMETYX for
previously treated advanced HCC currently in review with the U.S. Food
and Drug Administration –
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
About HCC
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

In 2016, Exelixis granted Ipsen exclusive rights for the
commercialization and further clinical development of cabozantinib
outside of the United States and Japan. Under the terms of the
Collaboration Agreement with Ipsen, Exelixis is entitled to receive a
tiered royalty of 22 percent to 26 percent of annual net sales.
