The increasingly challenging field of mRCC
Early 1940s:
experiments with
cytotoxic
chemotherapy1
Early 1980s: IFN-α and high-dose IL-2
used for RCC treatment
High-dose IL-2 approved in the USA
(1995). High treatment-related
toxicity; small number of durable
responses2
Sorafenib (USA 2005, EU 2006)3,4
Temsirolimus and
Bevacizumab plus IFN
(USA & EU 2007)3,4
Everolimus
(USA & EU 2009)3,4
Pazopanib
(USA 2009, EU 2010)3,4
Sunitinib (USA & EU 2006)3,4
Axitinib (USA & EU 2012)

Types of biomarker used in cancer management
Diagnostic biomarker Definition of tumour type,
stage and grade
e.g. BRAF V600 Screening biomarker Early detection of cancer in the general or at-risk populations
e.g. PSA antigen Pre-disposition
biomarker Identification of individuals at
risk of developing cancer
e.g. BRCA mutations
Prognostic biomarker Identification of the likely clinical disease course
e.g. MSKCC score Predictive biomarker Estimation of the individual
response to a specific treatment
e.g. HER-2 Pharmacodynamic
biomarker Changes after treatment
associated with target
modulation by an agent
e.g. PK analysis
Predicting Response to Treatment Based on Molecular/Genetic Markers
Molecular Marker Expression Level Predicted Response to Treatment
CAIX1 High Good response to immunotherapy
COX-21 High Good response to immunotherapy
HIF-1/HIF-22 High Good response to sunitinib
Genetic Marker Predicted Response to Treatment
Various nsSNPs3-6 Significant sunitinib toxicity/PFS
Loss of chromosomes 4, 9, or 17p4 Non-response to interleukin-2 (IL-2)
VHL loss-of-function mutation5 Good response to VEGF therapy
nsSNPs: nonsynonymous single nucleotide polymorphisms

Toxicity
Management
Who will develop these toxicities?
Can these toxicities be prevented?
In which settings are toxicities most relevant?
Are certain toxicities associated with response?
Can dose adjustment based on toxicity be used to optimize therapy?
Toxicity ↔ Clinical Outcome
Hypothyroidism • Median PFS higher in sunitinib treated pts (n=40) who developed hypothyroidism (10.3 v 3.6 mos; P=0.047) (Wolter et al ASCO 2008)
• Similar results in a series of 87 pts receiving sunitinib or sorafenib (Schmidinger et al Cancer 2011) Fatigue • PFS and OS improved in pts who developed fatigue in a retrospective experience including 770 pts treated with sunitinib (Donskov et al Ann Oncol 2012)
• May be related to longer drug exposure Hand-foot syndrome • Median OS improved in pts who developed HFS (38.2 v 18.9 mos; P<0.001) in 770 pts who received sunitinib (Pusanov et al ECCO 2013)
• ORR also improved (66.5% v 31.8%) Pneumonitis • In a series of 46 pts receiving mTORi’s, 30% developed pneumonitis (Dabydeen et al Eur J Cancer 2012)
• Pts developing pneumonitis had a lower rate of progressive disease as best response (14% v 56%) Hypercholesterolemia • Cholesterol changes during temsirolimus assessed in a phase III study (Lee et al CCR 2012)
• Cholesterol increase associated with longer survival (HR =0.77, P<0.0001) and PFS (HR 0.81, P<0.0001)

Efficacy is a key factor when selecting
first-line treatment, but there are also other considerations…
Achieving a continuum of care in mRCC
• Today, targeted agents are the standard of care for mRCC and long-term care may be achieved through effective therapy management
• But what is the most effective sequencing strategy?

The challenge of treatment in mRCC
• Benefits of tyrosine kinase inhibitors (TKIs) are
well established; however, there are limitations
– There are few complete responses
– Initial partial responses are followed by progression
– In other cases there is no objective benefit
• Drug resistance remains an ongoing obstacle to
successful treatment of mRCC
– Limits the success of therapy and reduces survival
