DESCRIPTION
Stephen Friend, July 6-8, 2011. WIN Annual Symposium, Paris, FRTRANSCRIPT
Searching for opportunities for WIN
it is more about how we do science than what
advantages of an open innovation compute space for building better models of disease
beyond siloed drug discovery- Arch2POCM
Personalized Medicine 101: Capturing Single bases pair mutations = ID of responders
Reality: Overlapping Pathways: 90% Phase I Cpds do not make it
WHY NOT USE “DATA INTENSIVE” SCIENCE
TO BUILD BETTER DISEASE MAPS?
Equipment capable of generating massive amounts of data
“Data Intensive Science”- “Fourth Scientific Paradigm” For building: “Better Maps of Human Disease”
Open Information System
IT Interoperability
Evolving Models hosted in a Compute Space- Knowledge Expert
It is now possible to carry out comprehensive monitoring of many traits at the population level
Monitor disease and molecular traits in populaFons
PutaFve causal gene

How is genomic data used to understand biology?
“Standard” GWAS Approaches Profiling Approaches
“Integrated” Genetics Approaches
Genome scale profiling provide correlates of disease Many examples BUT what is cause and effect?
Identifies Causative DNA Variation but provides NO mechanism
Provide unbiased view of molecular physiology as it
relates to disease phenotypes
Insights on mechanism
Provide causal relationships and allows predictions

This is killing drug discovery
We can generate effective and “safe” molecules in animals, but they do not have sufficient efficacy and/or safety in the chosen patient group.

“Remember the two
benefits of failure. First if
you do fail, you learn
what doesn’t work and
second the failure gives
you the opportunity to try
a new approach.”
Roger van Oech
Cost of Negative Ph II POC Estimated at $12.5 Billion Annually
• We want to improve health
• New medicines are part of this equation
• In this, we are failing, and we want to find a solution
”
Innovation is the ability to see change as an opportunity – not a threat
Let’s imagine….
• A pool of dedicated, stable funding
• A process that attracts top scientists and clinicians
• A process in which regulators can fully collaborate to solve key scientific problems
• An engaged citizenry that promotes science and acknowledges risk
• Mechanisms to avoid bureaucratic and administrative barriers
• Sharing of knowledge to more rapidly achieve understanding of human biology
• A steady stream of targets whose links to disease have been validated in humans
A globally distributed public private partnership (PPP) committed to:
• Generate more clinically validated targets by sharing data
• Help deliver more new drugs for patients
Arch2POCM
Arch2POCM: what’s in a name?
Arch: as in archipelago and referring to the distributed network of academic labs, pharma partners and clinical sites that will contribute to Arch2POCM programs
POCM: Proof Of Clinical Mechanism: demonstration in a Ph II setting that the mechanism of the selected disease target can be safely and usefully modulated.
Arch2POCM: a new drug development model?
• Pool public and private sector funding into an independent organization • Public sector provides stability and new ideas • Private sector brings focus and experience • Funding can focus explicitly on high-risk targets
• Pre-competitive model to test hypotheses from financial gain • Will attract top scientists and clinicians • Will allow regulators to participate as scientists • Will reduce perceived conflicts of interests – engages citizens/
patients • Will reduce bureaucratic and administrative overhead • Will allow rapid dissemination of information without restriction
- informs public and private sectors and reduces duplication
Toronto Feb-2011 meeting: ���output on Arch2POCM Feasibility
Pharma - 6 organisations supportive
Academic Labs - access to discovery biology and test compounds
Patient groups - access to patients more quickly and cheaply
- access to “personal data”
Regulators
- access to historical data
- want to help with new clinical endpoints and study designs
Arch2POCM: April San Francisco Meeting
• Selected Disease Areas of Focus: Oncology,, Neuroscience and Opportunistic (O, CNS and X, respectively)
• Defined primary entry points of Arch2POCM test compounds into overall development pipeline
• Committed academic centers identified: UCSF, Toronto, Oxford
• CROs engaged
• Evaluated Arch2POCM business model
• Two Science Translational Medicine manuscripts published
Entry Points For Arch2POCM Programs
Lead identification Phase I Phase II Preclinical
Lead optimisation
Assay in vitro probe
Lead Clinical candidate
Phase I asset
Phase II asset
- genomic/ genetic Pioneer target sources - disease networks
- academic partners - private partners - Sage Bionetworks, SGC,
Early Discovery
Arch2POCM and the Power of Crowdsourcing
• “Crowdsourcing:” the act of outsourcing tasks traditionally performed by an employee to a large group of people or community- such as WIN
• By making Arch2POCM’s clinically characterized probes available to all, Arch2POCM will seed independently funded, crowdsourced experimental medicine- advantage WIN
• Crowdsourced studies on Arch2POCM probes will provide clinical information about the pioneer targets in MANY indications- opportunity for WIN
ROI for Pharma Partner
• Option to in-licence asset after positive POCM
• Early data for new clinically validated (and invalidated) targets
• Easier access to the crowd of “proven” experts/ centers: leverage the crowd’s learnings to ID the most promising unmet medical need
• Collaborate in more open way with regulatory agencies and patient groups
• Jointly invalidate a larger number of pioneer targets
ArchPOCM Oncology Disease Area
Focus: Unprecedented targets and mechanisms
Novelty MOA and clinical findings
Arc2POCM Capacity: 5 targets/year for ~ 4 years
Gate 1: ~75% effort • New target with lead and Sage bionetworks insights on MOA
(increase likelihood of success), or • New target (enabled by Sage) with assay
Gate 2: ~25% effort • Pharma failed or deprioritized/parked compounds • Compound ID is followed by a Sage systems biology effort to define
MOA and clinical entry point
ArchPOCM Oncology: Epigenetics selected as the target area of choice
Top Targets:
• Discovery • Jard1 • Ezh1 • G9A
• Lead • Dyrk1
• Pre-Clin • ̀Brd4
ArchPOCM Oncology: Epigenetics selected as the target area of choice
ArchPOCM Oncology: Epigenetics selected as the target area of choice
Arch2POCM: Next Steps • Oncology and CNS Arch2POCM strategic design teams to generate project workflow plans and timelines (September)
• Define critical details of Arch2POCM leadership, organizational and decision-making structures • (Q3-Q4, 2011)
• Develop business case to support Arch2POCM programs (Q3-Q4, 2011)
• Obtain financial backing and launch operations in early 2012
Arch2POCM: ���an idea whose time has come
Ideas are only as good as your ability to make them happen.
"In a world of abundant knowledge, hoarding technology is a self-limiting strategy. Nor can any organization, even the largest, afford any longer to ignore the tremendous external pools of knowledge that exist.“ Henry Chesbrough
it is more about how we do science than what
advantages of an open innovation compute space for building better models of disease
beyond siloed drug discovery- Arch2POCM
Each of these are opportunities For the WIN Consortium
