    • Actionable Cancer Network ModelsAnd Open Medical Information Systems Stephen Friend MD PhD Sage Bionetworks (Non-Profit Organization) Seattle/ Beijing/ Amsterdam DFCI October 24th, 2011
    • Why not use data intensive science to build models of disease Current Reward StructuresOrganizational Structures and Tools Six Pilots Opportunities
    • What is the problem?•  Regulatory hurdles too high?•  Low hanging fruit picked?•  Payers unwilling to pay?•  Genome has not delivered?•  Valley of death?•  Companies not large enough to execute on strategy?•  Internal research costs too high?•  Clinical trials in developed countries too expensive?In fact, all are true but none is the real problem
    • What is the problem?We need to rebuild the drug discovery process so that webe6er understand disease biology before tes8ngproprietary compounds on sick pa8ents
    • What is the problem?Most approved cancer therapies assumed tumorindica8ons would represent homogenous popula8onsMost new cancer therapies are in search of single alteredcomponentsOur exis8ng tumor models o>en assume pathwayknowledge sufficinet to infer correct therapies
    • Personalized Medicine 101:Capturing Single bases pair mutations = ID of responders
    • Reality: Overlapping Pathways
    • The value of appropriate representations/ maps
    • “Data Intensive” Science- Fourth Scientific Paradigm Equipment capable of generating massive amounts of data IT Interoperability Open Information System Host evolving Models in a Compute Space- Knowledge Expert
    • what will it take to understand disease? DNA RNA PROTEIN (dark maGer)MOVING BEYOND ALTERED COMPONENT LISTS
    • 2002 Can one build a “causal” model?
    • Our ability to integrate compound data into our network analyses db/db mouse (p~10E(-30)) = up regulated = down regulateddb/db mouse(p~10E(-20) p~10E(-100)) AVANDIA in db/db mouse
    • Extensive Publications now Substantiating Scientific Approach Probabilistic Causal Bionetwork Models• >80 Publications from Rosetta Genetics Metabolic "Genetics of gene expression surveyed in maize, mouse and man." Nature. (2003) Disease "Variations in DNA elucidate molecular networks that cause disease." Nature. (2008) "Genetics of gene expression and its effect on disease." Nature.

    • hunter gathers - not sharing
    • Clinical/genomic data are accessible but minimally usableLittle incentive to annotate and curate data for other scientists to use
    • Mathematicalmodels of disease are not built to be reproduced orversioned by others
    • Assumption that genetic alterationsin human conditions should be owned
    • Lack of standard forms for sharing dataand lack of forms for future rights and consentss
    • Publication Bias- Where can we find the (negative) clinical data?
    • sharing as an adoption of common standards.. Clinical Genomics Privacy IP
    • Sage Mission Sage Bionetworks is a non-profit organization with a vision to create a commons where integrative bionetworks are evolved by contributor scientists with a shared vision to accelerate the elimination of human diseaseBuilding Disease Maps Data RepositoryCommons Pilots Discovery Platform

    • CTCAPClinical Trial Comparator Arm Partnership “CTCAP”Strategic Opportunities For Regulatory Science Leadership and Action FDA September 27, 2011
    • Clinical Trial Comparator Arm Partnership (CTCAP)  Description: Collate, Annotate, Curate and Host Clinical Trial Data with Genomic Information from the Comparator Arms of Industry and Foundation Sponsored Clinical Trials: Building a Site for Sharing Data and Models to evolve better Disease Maps.  Public-Private Partnership of leading pharmaceutical companies, clinical trial groups and researchers.  Neutral Conveners: Sage Bionetworks and Genetic Alliance [nonprofits].  Initiative to share existing trial data (molecular and clinical) from non-proprietary comparator and placebo arms to create powerful new tool for drug development. Started Sept 2010
    • Shared clinical/genomic data sharing and analysis will maximize clinical impact and enable discovery 
    • Non-­‐Responders Project To identify Non-Responders to approved Oncology drug regimens in order to improve outcomes, spare patients unnecessary toxicitiesfrom treatments that have no benefit to them, and reduce healthcare costs
