An opportunity An opportunity
For the first time, diseases can be defined by molecular fingerprints or profiles
Mechanistic pathways of diseases can be elucidated
Symptomatic descriptors can be replaced by meaningful tools for stratification
These tools will enable truly personalized medicine
Medicine todayMedicine today
Drugs are developed to treat all patients with the same clinical diagnosis - “one size fits all”
Many drugs only work in less than half of the patients for which they are prescribed
Over 100,000 people die annually from drug related adverse events - a ‘top 10’ cause of death

Three horizons of MURDOCK StudyThree horizons of MURDOCK Study
Horizon 1
•Use assets on hand to generate molecular data
•Generate hypotheses by leveraging bioinformatics
Horizon 1.5•Engage community
•Build community registry
Horizon 2
•Validate hypotheses prospectively
•Apply new knowledge to local community through partnership with local medical community
•Improve human health

Open discovery platform allows for discovery of novel protein biomarkers (host or viral-specific) that may be associated with treatment response and/or HCV genotype
These biomarkers, along with others, will be typed in a large HCV patient cohort
