Pre-competitive projects can work to deliver science and change culture

• Established 2003

• 200 scientists; labs in Toronto, Oxford and Stockholm

• Funded by - Private: GSK, Merck, Novartis, Lilly, Pfizer, Life

Tech- Govt: Canada, Ontario, Sweden - Charities: Wellcome Trust, Wallenberg Foundation

The SGC: A model for sharing in experimental science

SGC: open access works• 1000 human protein structures – all available without

restriction– ~30% of novel human proteins in PDB per annum– Structures used to be “competitive”

• >100 structures of proteins from parasitic protozoa– Chemical validation for drug targets in toxoplasmosis (Nature,

2010) and sleeping sickness (Nature, 2010)

• 500 cDNA clones distributed freely every year (academia, biotech, pharma)

• 75 visiting scientists per annum

Why does the SGC model work?

• SGC model allows opportunity to work with the very best – 200+ collaborations

• SGC model drives fast data dissemination– On average, each SGC structure enters public domain 18-24

months in advance of academic norms

• SGC model promotes collaboration– Average of >3 non-SGC authors for each paper

• SGC model focuses on milestones– 1000 structure target (2004-2011); 1,100 achieved to date

• No IP

In biomedicine, the system is the greatest hurdle to the discovery of innovative medicines

The funding system does not support “innovation”

How have we responded to the genome?

Another way of looking at it

• 65% of 2009 kinase publications on the 10% of the kinome that was “hot” in early 1990’s

• 5% of 2009 kinase publications on the 300 kinases that were the least studied in 2002

Others also feel trapped by the system

What should the scientific community do?

1. Pay less attention to the literature2. Be more daring when funding research3. Support young scientists to dream bigger

The Challenge of Pioneer Drug Discovery

• Number of pioneer drugs (Priority Reviewed NCEs) has not increased from 1993-2008

• Investment in pharmaceutical R&D has risen dramatically over this period

• >90% failure rate in clinical trials for pioneer drugs due to lack of efficacy

Impact on pharma and biotech in 2009

• $100B in R&D

• 21 drugs approved (7 truly novel)

• 70,000 pharma employees let go

• Investment houses writing that pharma should “get out of R&D”

• Industry relying on academia for “innovation”

What can we do?

Structural Genomics Consortium

Why not change the system?

Let’s imagine….

• A steady stream of pioneer targets whose links to disease have been validated in humans

• Engagement of 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

Imagine…

• Pooled public and private sector funding into independent organization• Public sector provides stability and new ideas• Private sector brings focus and experience• Funding can focus explicitly on high-risk targets

• A pre-competitive model to test hypotheses• Disassociates science 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

Progress

• arch2POCM concept• University of Toronto, University of Oxford, University of

California, San Francisco committed• CIHR and Genome Canada helping drive• Six large pharma engaged (none committed yet!)• Regulators (FDA) keen to be involved as participants• Patient groups fully engaged• Therapeutic foci selected

• Oncology, neuroscience and inflammation

• Business plan being written

What is needed

• A set of public funders keen to take the “risk” and drive the concept (Canada???)

• Leadership identified

• A core set of pharmaceutical funders

And when we succeed?• Less duplication• Broader scientific assessment• Faster dissemination of data• Pool academic and multiple pharma strengths and

funding – shared risk• Increasing knowledge of human biology (which will in

turn reduce attrition?)

More clinical POCs on novel targets….more clinically validated targets …..more novel drugs

Potential opportunities for research and business

1. Academic partnerships that deliver new targets2. High value clinical trials3. Contract research organizations with leading edge science4. Biotech companies with compounds and technologies

Potential impact

5. More industry funding for University and Hospital-based research6. A business community built on high value service7. A clinical trial network that works on innovative targets8. Better business climate for biotech due to enhanced links with industry

Commercial opportunities for Canada in the new “open access” drug discovery ecosystem
