(NASDAQ: EXEL)
Forward-Looking Statements
This presentation, including any oral presentation accompanying it, contains forward-looking
statements, including, without limitation, statements related to: future clinical development of
cabozantinib and the availability of additional data from the METEOR trial; future regulatory filings,
potential approval, and launch of cabozantinib in RCC; and, continued development and clinical,
therapeutic and commercial potential of, and opportunities for, cabozantinib. These statements are
based on Exelixis’ current expectations, assumptions, estimates and projections about its business and
its industry and involve known and unknown risks, uncertainties and other factors that may cause
results, timing, levels of activity, performance or achievements to be materially different from any actual
results. Words such as “intend”, “potential,” “expect,” “will,” “anticipate,” “assume,” “plan,” or the
negative of such terms or other similar expressions, identify forward-looking statements, but the
absence of these words does not necessarily mean that a statement is not forward-looking. In addition,
statements that refer to expectations, projections or characterizations of future events or their timing are
forward-looking statements. Factors that might cause such a difference include, without limitation: risks
related to clinical trials and the regulatory approval pathway for cabozantinib; risks related to whether
Exelixis compounds demonstrate safety and efficacy; risks and uncertainties related to Exelixis’
compliance with applicable regulatory requirements, including healthcare fraud and abuse laws and
post-marketing requirements; market competition; changes in economic and business conditions; and
other factors discussed under the caption “Risk Factors” of Exelixis’ quarterly report on Form 10-Q filed
with the Securities and Exchange Commission (SEC) on August 11, 2015 and in Exelixis' other filings
with the SEC. The forward-looking statements made in this presentation, including any oral presentation
accompanying it, speak only as of the date on which the statements are made. Exelixis expressly
disclaims any duty, obligation or undertaking to release publicly any updates or revisions to any forwardlooking statements contained herein to reflect any change in Exelixis' expectations with regard thereto
or any change in events, conditions or circumstances on which any such statements are based.

COMETRIQ® (cabozantinib capsules) Approval Status
The European Commission has granted COMETRIQ® (cabozantinib capsules) conditional
marketing authorization for the treatment of adult patients with progressive, unresectable
locally advanced or metastatic MTC. Similar to another drug approved in this setting, the
approved indication states that for patients in whom Rearranged during Transfection (RET)
mutation status is not known or is negative, a possible lower benefit should be taken into
account before individual treatment decisions.
•  Please refer to the latest approved European Summary of Product Characteristics for
full European Union prescribing information, including contraindication, special warnings
and precautions for use at www.sobi.com once posted.
COMETRIQ® is currently approved by the U.S. Food and Drug Administration for the
treatment of progressive, metastatic medullary thyroid cancer (MTC).
•  Please see full U.S. prescribing information, including Boxed WARNINGS, at
www.COMETRIQ.com/downloads/Cometriq_Full_Prescribing_Information.pdf

COMETRIQ® (cabozantinib capsules) Safety
Important Safety Information, including Boxed WARNINGS
WARNING: PERFORATIONS AND FISTULAS, and HEMORRHAGE
Serious and sometimes fatal gastrointestinal perforations and fistulas occur in COMETRIQtreated patients.
Severe and sometimes fatal hemorrhage occurs in COMETRIQ-treated patients.
COMETRIQ treatment results in an increase in thrombotic events, such as heart attacks.
Wound complications have been reported with COMETRIQ.COMETRIQ treatment results in
an increase in hypertension. Osteonecrosis of the jaw has been observed in COMETRIQtreated patients. Palmar-Plantar Erythrodysesthesia Syndrome (PPES) occurs in patients
treated with COMETRIQ. The kidneys can be adversely affected by COMETRIQ. Proteinuria
and nephrotic syndrome have been reported in patients receiving COMETRIQ. Reversible
Posterior Leukoencephalopathy Syndrome has been observed with COMETRIQ. Avoid
administration of COMETRIQ with agents that are strong CYP3A4 inducers or inhibitors.
COMETRIQ is not recommended for use in patients with moderate or severe hepatic
impairment. COMETRIQ can cause fetal harm when administered to a pregnant woman.
Adverse Reactions – The most commonly reported adverse drug reactions (≥25%) are
diarrhea, stomatitis, palmar-plantar erythrodysesthesia syndrome (PPES), decreased weight,
decreased appetite, nausea, fatigue, oral pain, hair color changes, dysgeusia, hypertension,
abdominal pain, and constipation. The most common laboratory abnormalities (≥25%) are
increased AST, increased ALT, lymphopenia, increased alkaline phosphatase, hypocalcemia,
neutropenia, thrombocytopenia, hypophosphatemia, and hyperbilirubinemia.

Abstract 4LBA
Cabozantinib versus everolimus in patients
with advanced renal cell carcinoma: results
of a randomized phase 3 trial (METEOR)
T. Choueiri, B. Escudier, T. Powles, P. Mainwaring, B. Rini, F. Donskov, H.

for the METEOR investigators
Presented at the European Cancer Congress, Vienna, 26 September 2015
Introduction
•  Drugs targeting VEGF and its receptors, or the mammalian
target of rapamycin (mTOR), are standard therapies in RCC
•  Inactivation of the von Hippel-Lindau tumor suppressor protein
in clear cell RCC results in upregulation of VEGF, MET, and
AXL1
•  Increased MET and AXL expression has been associated with
poor prognosis and resistance to VEGFR inhibitors in RCC1,2
•  Resistance to targeted therapy represents a major challenge
to improving clinical outcomes of patients with RCC

Cabozantinib
•  Cabozantinib is an oral small molecule inhibitor of tyrosine
kinases including MET, VEGF receptors, and AXL1
•  A single arm trial of cabozantinib demonstrated clinical activity
in heavily pretreated RCC patients2
•  The international, open-label phase 3 METEOR study
evaluated the efficacy and safety of cabozantinib compared to
everolimus in VEGFR TKI pretreated RCC patients

METEOR Study Conclusions
•  Cabozantinib significantly improves PFS compared to
everolimus in RCC patients after prior VEGFR TKI therapy
•  Cabozantinib improved the objective response rate
•  Overall survival results at the interim analysis show a
strong trend favoring cabozantinib
•  Cabozantinib's safety profile is acceptable and tolerability is
similar to other TKIs in this population
•  Cabozantinib represents a potential new treatment option
for second or later line therapy for RCC

Progression Free Survival and Duration of
Therapy in METEOR
•  METEOR protocol allows treatment beyond progression if there is evidence
of clinical benefit
•  Median duration of therapy longer than median PFS for the PFS population
–  Mature data with 11 month minimum follow up vs 6 month minimum follow up
in OS population

Additional Cabozantinib Development
•  CABOSUN – cabozantinib vs sunitinib in first line RCC
–  ALLIANCE/CALGB randomized Phase 2 trial, PFS is primary endpoint
–  Enrollment completed March 2015, data expected in 2016
•  Cabozantinib in combination with Checkpoint Inhibitors
–  Cabozantinib plus nivolumab or plus nivolumab and ipilimumab in patients with GU tumors
(including bladder, RCC)
–  NCI/CTEP Phase 1b trial now recruiting
•  CELESTIAL – cabozantinib vs placebo in second line HCC
–  Randomized, blinded Phase 3 study in HCC pts who have received prior sorafenib
–  OS is the primary endpoint, data anticipated in 2017
•  NSCLC, ongoing Phase 2 trials addressing different patient populations
–  EGFR WT ECOG/ACRIN randomized Phase 2 data presented at ASCO
–  Evidence for a PFS and OS benefit for cabozantinib or cabozantinib plus erlotinib vs erlotinib
–  Ongoing discussions regarding a potential Phase 3 study
