' Precision = Personalized = Individualized

' Pharmacogenomics ' Genetic medicine

' Establishing the clinical care based on the individual's genetic

information and biomarker profile

' P5 medicine

' Preventive factors measured within a population '' establish

preventive measures for at-risk individuals '' personalized and

participatory healthcare

' Survey, monitor and diagnose RISK

' Establish SPECIFIC treatment, OPTIMAL drug selection

' Treat the patient not the disease

Challenges of the

current healthcare

' Genetic polymorphism + biomarkers '' disease


' Elevated risk of  low therapy effectiveness and


' Negative financial


' Disease costs

' Clinical trial failures


' Drug retrievals

Opportunities &


'' the need of therapy individualization

' Optimal drug selection based on

' Medical and familial history

' Genetics/genomics

' Exposome

' Omics '' gene mapping (HapMap), gene sequencing, identification of

SNPs'' disease diagnosis

' Preventive approach less financial implications

' Shared decision making in the therapy selection ' trust and

perception regarding the heathcare system '' indirect + effect on the

therapeutic outcomes

' Biobanks if linked to Electronic Medical Records '' translation of

genotype-phenotype data to clinical care (challenges patient


' ' knowledge in drug development + better clinical trial design ' risk

of failure pre and post marketing of drug

Diagnostic tools (1)

' Biomarkers

' Biological measures of a biological state

' Microarray

' Lab-on-a-chip

Diagnostic tools (2)

' DNA chips (screenning up to

100000 SNPs in a few hours ''

diagnose phenotypic variations)

' Eg. DMET Plus (Affymetrix) ' 1936

genetic variants across 231 relevant

genes, including 100% coverage of the

PharmaADME genes (32)

 and 95% of

the PharmaADME Core Markers ''

predictory of the pharmacokinetic

variability '' improve drug

development process (effectiveness',


Pharmocogenomics in

drug development (1)

Pharmocogenomics in

drug development (2)

' SNPs in the genes of disease, drug transport, drug

metabolism, drug target '' identify genomic

markers '' predict disease response to drug

' Pharmacogenetics used for in vitro-in vivo

correlations '' better clinical trial design

' Pharmacogenomics ' drug labeling

Eg. Genomic data '' expression level of CYP3A gene '' anticipate effect of drugs

like Tacrolimus (immunosuppresiv)

idem CYP2D6 '' Tamoxifen (anticancer agent, selective estrogen modulator)

Idem CYP2C9 ''Warfarin (anticoagulant)

Idem HLA-B*5701 '' Abacvir (antiretroviral) hypersensitivity biomarker

The influence of

pharmacogenetics on plasmatic


Old vs new approach in

drug/dose selection

Challenges in the


Current healthcare regulations

regarding genetic testings (1)

1. Laissez-Faire

' Users have full freedom to request new tests and

disclose the results

' Heath providers can discriminate their users

according to their genetic risk

' Applied in: Australia, Canada, China, Japan, Ireland,

Korea, Russia, Portugal, Spain, South Africa

2. Disclosure Duty

' Users cannot be required to take the test

' Results can't be disclosed

' Discrimination '

' Applied in Germany, New Zealand, UK

Current healthcare regulations

regarding genetic testings (2)

3. Consent Law

' Users can keep private or disclose the results (for

lower insurance premium)

' Discrimination '

' Applied in Switzerland, Netherland

4. Under strict prohibition

' Healthcare providers cannot use the genetic

information for rating

' Discrimination '

' Applied in Austria, Belgium, France, Israel, Italy,

Norway, USA


' The right treatment to the right person at a right


' Human genome project

''Drug Design '' individualized therapy

''Improved, early diagnosis

''Measurement of disease predisposition

''Disease course monitoring

' Under evaluation ' challenges regarding

implementation '' lack of a harmonized

healthcare regulation

Thank you!

If it were not for the great variability

among individuals, medicine might as well

be a science and not art. (Frueh, 2005)
