“Selfmonitoring = Trend of 2014” The future of medicine
Biomarkers in Personalized Health(care) an evolving role
• From only diagnosis
• To Translational Medicine
• To Personalized/Precision/Targeted Medicine
• To Personalized Healthcare
• To Person-centered Health(care)

But …
Knowledge and Innovation gap:
1. What to measure?
2. How much should it change?
3. What should be the follow-up for me?

Exponential technologies
“The only constant is change, and the rate of change is
increasing”
We are at the knee of the exponential curve
Buzzwords Progress and beyond
You are the CEO of your own healthcare team
Exponential technologies
Disruptive innovation
Digitalizing yourself
Sitting is the new smoking
Uber-ization of healthcare
The future is already here, it’s just not evenly distributed …
What’s normal for me is not normal for you
Do things different
Don’t think out of the box, just think there is no box !

Exponential developments in biomarker technologies
• Next generation sequencing • Large level of detail on genome level (DNA, RNA) • Sequencing per patient is becoming practice • Allows risk analysis and therapy selection
• Mass spectrometry
• Large level of detail on metabolic level (proteins, metabolites)
• Analysis of blood, urine, cells, tissues, hair, etc all possible • Allows monitoring of disease and treatment effects
• Imaging • Large level of detail on intact in vivo level • Analysis of any tissue, real time
• Allows spatial view of intact organs and organisms
Genome sequencing will become much cheaper !
Next in Next Generation Sequencing • Trends:
₋ Further reduction in sequencing costs ₋ Computational power ₋ Machine learning to analyse (big) data ₋ Link molecular diagnosis to cellular therapies
Also beyond the oncology field:
• Volker: Intestinal surgery → XIAP → Cord blood
• Beery twins: Cerebral palsy → SPR → Diet 5HTP
• Wartman: Leukemia → FLT3 → Sunitinib
• Gilbert: Healthy → BRCA → Mas/Ovarectomy
• Snyder: T2Diabetes → GCKR, KCNJ11 → Diet, exercise
• Lauerman: Scotoma, leg → JAK2 → Aspirin
• Bradfield: Healthy → CDH1 → Gastrectomy

But …
Knowledge and Innovation gap:
1. What to measure?
2. How much should it change?
3. What should be the follow-up for me?
Most important for biomarkers in Personalized Healthcare:
Focus on the end user: the patient

Lab values Clinical outcomes
Patient important outcomes
Pain
Pubmed Search query
Critical appraisal tool
Mobility Fatigue

How to move forward?
1. Focus on the end user
2. Validate more biomarkers in one go
3. System biology
4. Define, share and act on “Good Biomarker Practices”
5. Build biomarker development pipelines
6. Develop translational DIY technologies
7. Interpret data with self-normalisation
8. Interdisciplinary teamwork

Some items in need of standardisation:
• Reproducibility, quality requirements
• Study design & statistical power
• Variability & heterogeneity
• Specimen acquisition & pre-analytics
• Sample preparation
• Patient & associated clinical data
• Analytical standards & quality control
Not reinvent the wheel.
Standardisation, harmonisation, knowledge sharing needed in:
1. Assay development
2. Clinical validation
3. Biomarker qualification
• Assay/platform development
• Quality system manufacturing
• Data analysis & management
• Regulatory requirements
• Ethical, IP & legal aspects
• Early HTA
• Quality in documentation & publication
