Frequent cancers include high number of very rare genomic segments
Stephens, Nature, 2012
(whole genome sequencing breast cancers)
Working hypothesis
• Targeting mechanisms that lead to cancer progression can improve patient’s outcome
• These mechanisms are individual
• Goal: to identify the mechanism of cancer progression at the individual level, in order to target it
Precision Medicine
Concept: Identify the targets to be treated in each patient
Molecular analysis
Therapy matched to genomic alteration
Andre, ESMO, 2012
Target identification
What is the optimal Biotechnology ?
What is the optimal Algorithm ?
Clinical evidence
Outline
• Stratified medicine
• Personalized medicine
Stratified medicine• Drug development or implementation in a strate
defined by a molecular alteration
FGFR1 amplification: 10% of breast cancer
Translational research to feed stratified medicine
FGFR1 inhibitors present higher sensitivity
on FGFR1-amplified CC
FGFR1: amplification in 10% BC
Set-up genomic test(FISH)
Run phase II trialTesting the FGFR1 Inh in patients withFGFR1 amp BC
Research and medical questions related to stratified medicine
• How to facilitate translation of discoveries ?• Develop translational research units
• How to set-up a molecular assay for stratified medicine ?• Develop genomic units for clinical use
• How to optimally run trials of stratified medicine ?• Set-up molecular screening programs

Molecular screening: Challenges
• No research in stratified medicine without molecular screening programs
Evolution:GENOMIC DISEASES ARE BECOMING TO RARE OR COMPLEX TO ALLOW DRUG DEVELOPMENT IN GENOMIC SEGMENTS
How to move forward ?
Stephens, Nature, 2012
Are we going to make a drug developmentfor this AKT1 mut / FGFR1 amp segment ?
Solution to improve outcome with targeted therapies in the genomic era:
test the algorithm not the drug
How to move there ???
