Key is to have a good view inside
High need for molecular tools that allow a look into the black box
and improve disease management: biomarkers
Drug exposure ?
Diagnosis ?
Cross-species differences ?
Patient classification ? Prognosis ?
Target engagement ?
Modulation of mechanism ?
Off-target drug effects ?
Treatment Phenotype
Mechanism ?
Other (latent) diseases ?

Biomarkers
{Biomarkers definition working group, 2001 }
Definition: ‘a characteristic that is objectively measured and evaluated as an
indicator of normal biological processes, pathogenic processes, or
pharmacologic responses to a therapeutic intervention’
Or ‘Whatever works in adding value’
Molecular biomarkers provide a molecular impression of a biological system
(cell, animal, human)
Biomarkers can be various sorts of data, or combinations thereof

Does the compound cause its intended pharmacological/
functional effects?
Does the compound have beneficial effects on disease or
clinical pathophysiology?
What is the therapeutic window (how safe is the drug)?
How do sources of variability in drug response in target
population affect efficacy and safety?

Biomarker strategy: (data-driven) Decisions
To be made during testing of drug in preclinical and clinical disease models:
Target engagement? Effect on disease?
yes yes !
no no
• No need to test current
drug in large clinical trial
• Need to identify a more
potent drug
• Concept may still be
correct
• Concept was not correct
• Abandon approach
• Proof-of-Concept
• Proceed to full
clinical
development

The innovation gap in biomarker research & development

• Imbalance between biomarker discovery and application.
• Gap 1: Strong focus on discovery of new biomarkers, few biomarkers
progress beyond initial publication to multi-center clinical validation.
• Gap 2: Insufficient demonstrated added value of new clinical biomarker and
limited development of a commercially viable diagnostic biomarker test.

– Many new biomarkers are panels (RNA, protein, biochemical, imaging)
– Not wise to discover yet an other biomarker
– Focus on selecting the best biomarker (panels) among those already
found (scientific and patent literature, databases, etc)
– Develop those biomarkers tot clinically applicable tests

Reasons for biomarker innovation gap
24
• Not one integrated pipeline of biomarker R&D
• Publication pressure towards high impact papers
• Lack of interest and funding for confirmatory biomarker studies
• Hard to organize multi-lab studies
• Biology is complex on organism level
• Data cannot be reproduced
• Bias towards extreme results
• Biomarker variability
• …

Uptake of new biomarkers in healthcare
Research/technology push:
Biomarkers can and should provide the molecular part of this healthcare model in
monitoring and follow-up
Daily practice in clinical assessment:
Combination of personal opinion (patient and physician), physical examination, clinical
chemistry to generate personal profiles
New biomarkers are added where deemed useful by physician
Act accordingly in follow-up care (more or less personalized)
Medication (a.o. personalized medicine)
Nutrition (a.o. individualized diets)
Life style (a.o. individualized exercise, counseling)
Slow uptake of new biomarkers
Limited by careful / conservative attitude of clinicians (added value of new biomarker?)
Limited by reimbursement options by insurers (increasingly important)

Formula: 0.56x(TEN28) + 0.28x(SW28) + 0.70ln(ESR) + 0.014(GH)

Companion Diagnostics
Right drug
in right patient
at right dose
at right time
In other words:
Apply a well characterized therapy in a biological system you know well
to treat a disease you understand well, in a way that you know works.
Use (molecular) biomarkers as diagnostic companions of a drug.
New: diagnostic companions to a person !

Metabolic syndrome
metabolic disturbance local inflammation
Not a single cause but complex multifactorial diseases
Disturbed equilibrium between multiple pathways and key components
A system biology approach is needed
For discovery research, diagnosis and treatment
Continuous monitoring really pays off
Most effective therapy is ‘eat better, move more’ (lifestyle change)

Working in complex human biological systems requires a systems biology approach
Way forward:
1. Focus on key processes
2. Measure key node biomarkers
3. Convert to a functional fingerprint assay panel
4. Make actionable personalized decision on health /
disease management
5. Test added value in real life through field labs

Field labs: test health care concepts in real life
• Build field lab with pre-diabetic patients, physicians, dietitians, insurers, etc
• Measure individual ‘risk’ parameters for metabolic syndrome +/- challenge
• phenotypes, clinical chemistry, specific Omics, etc
• Convert data into a personal profile + personalized health advice
• life style +/- nutrition +/- pharmaceutical drugs
• Test personalized health concept in field lab following P4 medicine principle
• Alliance “Expedition Sustainable Care, starting with diabetes”

Field labs: implementation in 1st line health care
• Implementation-plan ‘personalized diagnosis
of (pre)diabetic and their lifestyle treatment in
Dutch Health care’.
• Use of OGTT as a stratification biomarker for
subgroups of (pre)diabetic patients
• Use diagnosis for a tailored lifestyle
(and medical) treatment
for these subgroups
Being implemented in

High attrition in most chronic diseases
{Source: Kola, 2008, Nature 83, 2: 227}
• Multifactorial causes of disease, mostly not well understood
• Risk factors include both molecular as lifestyle/environmental factors
• Treatment is often symptom-based, not mechanism-based
• System approach in diagnosis and treatment (systems medicine)
• Need improved disease definitions and understanding

From clinical Omics to personalized treatment:
• 12 families with liver disease and dilated cardiomyopathy (5-20 years)
• Initial clinical assessment didn’t yield clear cause of symptoms
• Specific sugar loss of serum transferrin identified via glycoproteomics
• Genetic defect in glycosylation enzyme identified via exome sequencing
• Outcome 1: Explanation of disease
• Outcome 2: Dietary intervention as succesful personalized therapy
• Outcome 3: Glycoprofile developed as diagnostic test by mass spectrometry

The innovation gap in biomarker development
56
• Imbalance between biomarker discovery and application.
• Gap 1: Strong focus on discovery of new biomarkers, few biomarkers progress beyond
initial publication to multi-center clinical validation.
• Gap 2: Insufficient demonstrated added value of new clinical biomarker and limited
development of a commercially viable diagnostic biomarker test.

Needed: A Biomarker Development Pipeline
57
• A focus on application of innovation, not on new technologies or biomarker discovery
• The innovation is a clinically validated biomarker that can be applied as diagnostic test
• Bring together available state-of-the art biomarker expertise in an industrial process flow
• Sponsors and end-users define objectives (a.o. pharma, diagnostics, patients)
• Shared biomarker R&D in Open Innovation Network based on Public-Private-Partnership

• Build an efficient biomarker development pipeline in Netherlands
• Bring all stakeholders together in a functional open innovation network based on public-private-partnerships
• Have end-users (patients) direct biomarker discovery in beginning
• Improve progress of biomarkers from discovery to clinical implementation
