    • What s needed to engage “data intensive” science for disease maps?•  Three critical components: –  Big databases, organized (connected) to facilitate integration and model building 1) Complex DB •  GE Health, IBM, Microsoft, Google, and so on EMR Results dbGAP KeggGO,etc , . GEO –  Data integration and construction of predictive models •  Computational, math/stat, high-performance computing, and biological expertise •  Significant high-performance computing resources 2) –  Tools and educational resources to translate complex material to a hierarchy of 3) of “users”and ways to cite model-publish
    • Recognition that the benefits of bionetwork based molecularmodels of diseases are powerful but that they requiresignificant resourcesAppreciation that it will require decades of evolvingrepresentations as real complexity emerges and needs to beintegrated with therapeutic interventions

    • Warburg Effect Studied by the Federation s Genome-wide Network and Modeling Approach Warburg effect: the association of aerobic glycolysis, an inefficient way for ATP generation, with cancer cell and their progression. Linked with rapidly dividing cells. Two Key Questions: 1.  Are cancer cells genetically decoupled from the altered metabolism that is seen in rapidly dividing cells? 2.  Is there evidence that cancer outcomes are associated with altered metabolic circuits?

    • We still consider much clinical research as if we were"hunter gathers# not sharing soon enough - .
    • Assumption that genetic alterationsin human conditions should be owned
    • Patients and control of their own data still not engaged often enough
    • Publication Bias- Where can we find the negative clinical data?
    • The Current Pharma Model is Broken: High costs, redundant failures, risk aversion and looming patent cliffs plague the industry•  In 2010, the pharmaceutical industry spent ~$100B for R&D•  Half of the 2010 R&D spend ($50B) covered pre-PH III activities•  Half of the pre-PH III costs ($25B) were for program targets that at least one other pharmaceutical company was actively pursuing•  Only 8% of pharma company small molecule PCCs make it to PH III•  In 2010, only 21 new medical entities were approved by FDA –  15 small molecules; 7 received “priority” reviews (3 of which were orphan) –  6 biologics; 3 received priority review – all recombinant enzymes for orphan diseases April  16-­‐17,  2011   79 San  Francisco  
    • The time is ripe to provide an improved business model toensure that more high risk/high opportunity targets gain proof of clinical mechanism (POCM) April  16-­‐17,  2011   80 San  Francisco  
    • Arch2POCM
    • Arch2POCM MissionTo establish a pre-competitive stream of drug development data and POCM candidates that: 1.  Will focus on high risk/high opportunity targets and be powered by failed Ph II compounds 2.  Will inform the industry regarding those targets that are validated for clinical proof of concept mechanism (POCM) and those that are not 3.  Will drive down redundant efforts in discovery and early development 4.  Will allow clinicians and academics “BIG” to work on novel compounds and share their data with EMEA and FDA joining the dialog on the targets as not about a product to be approved 5.  5. Will allow Industry to generate proprietary compounds with IP for filing benefiting from the POCR in the common open stream April  16-­‐17,  2011   82 San  Francisco  
    • Arch2POCM Can Serve As a Pilot For The Entire Pharmaceutical Industry•  Arch2POCM is a new drug development model that is intended to allow participants to: –  Eliminate redundant discovery and early development activities –  Leverage all information generated by the Arch2POCM to reduce the cost of failure –  Take advantage of validated POCM s –  Obtain value for existing assets that are not currently getting developed April  16-­‐17,  2011   83 San  Francisco
