Anticipating a world in which pharmaceutical companies outsource all R & D

SGC Oxford SGC Toronto SGC Stockholm

Early-stage drug discovery research:

Skating to where the puck will be

NON CONFIDENTIAL

1.  Global of funding for health and drug discovery research will not increase

2.  On average, over past 30 years, fewer drugs with novel mechanisms are being approved per dollar

3.  Pharma is retrenching from research; merging, “right-sizing”, seeking locations where costs are lower

4.  Pharma exiting completely from more challenging areas of drug discovery (i.e. neurosciences)

5.  Morgan Stanley report advises pharma to go the whole hawg: “get out of R+D altogether”

Situation

1.  Research and development outside pharma walls

2.  $20B R+D spent more globally – more competitive.

3.  Academia will feel pressure to become more “industry-like”

4.  More biotech’s will emerge

5.  Knowledge will become increasingly balkanized

6.  At the end of the day, this will only re-shuffle. If only 1-5 occur, cost of drug discovery and cost of healthcare will not decrease, and society’s unmet needs will remain unmet.

How drug discovery will evolve

What change is required to deliver new medicines more effectively/cheaper

1.  Better and broader understanding of biology -  Reagents and tools to facilitate research -  Deeper understanding of patient heterogeneity

2.  Assays that better reflect behaviour of drug candidates in humans -  Disease-relevant assays with clinical material

3.  Less duplication in drug development –  Partnerships to determine efficacy of “pioneer” targets

4.  More community involvement –  Mechanisms to allow all scientists to participate in drug

discovery –  More patients involvement/understanding

How to effect this change?

1.  Focus on science, not on IP generation

2.  Take advantage of the passion to make a difference

3.  Involve clinicians more closely in drug discovery

4.  Fund the effort through open access public-private partnerships - from discovery to clinical proof-of-concept

5.  Make data available from beginning to end to empower and involve scientists

Two possible ways forward for Ontario and Canada

1.  Try to compete within the existing drug discovery ecosystem -  Same strategy as always -  Not so sure that we have proven we can compete

2.  Be part of changing drug discovery ecosystem -  Get “first mover” opportunity -  Play to the strengths of Canadians and Canadian science

(effective, efficient, collaborative) -  Does not stop us from competing in existing system

Why public-private partnerships?

Better and broader understanding of biology will not quickly come within existing academic structure

A Network of Disease Institutes 1.  Better and broader understanding of biology

3.  Less duplication in drug development –  Partnerships to determine efficacy of untested targets

Better prediction of drug efficacy Problem

Animal and cell-based models of disease poorly predict the efficacy of drug candidates (small molecule or biologic); most diseases are poorly understood

Solution Create a network of science-based Disease-Focused Institutes to tackle the diseases of greatest societal importance

Outcome 1.  New targets for therapeutic intervention 2.  Disease relevant assays 3.  Biomarkers for disease progression and treatment

A Model for Disease Focused Institutes

1.  Each Institute focused on specific disease [e.g. pancreatic cancer(s)]

2.  Science funded stably by public and private sectors 3.  Human is the disease model; must link to clinicians 4.  All data generated, assays, ideas within the four walls are

open access 5.  Industry scientists welcome to work at the Institute and have

complete access to science 6.  Set up quantitative objectives; impact measured against

milestones as well as customary academic assessment criteria

7.  The science must be genome or system-based, not biased by current thinking

Generating more targets with clinical PoC 1.  Better and broader understanding of biology

-  Reagents and tools to facilitate research (SGC) -  Deeper understanding of patient heterogeneity (ICGP)

2.  Assays that better reflect behaviour in humans -  Disease-relevant assays with clinical material (Network of

Disease Institutes)

3.  Less duplication in drug development –  Partnerships to determine efficacy of untested targets

(Open access clinical PoC)

4.  More community involvement –  Mechanisms to allow all scientists to participate in drug

discovery (BioHub; Sage Bionetworks) –  More patients involvement/understanding (Open access

clinical PoC)

Reducing waste in clinical development Problem

Most novel targets are pursued by multiple companies without disclosure of the data. With a 90% failure rate in clinical trials, this wastes resource, hampers learning and subjects patients to compounds destined to fail (and likely to cause harm).

Solution Pursue large numbers of “never before been drugged” targets to clinical PoC within an open access consortium

Outcome 1.  Clinically-validated targets at reduced cost 2.  Reduced patient harm 3.  More knowledge about role of target in human biology

A model for open access clinical PoC Consortia

1.  Funded by public and private sectors 2.  Science, not market, driven 3.  Governed by funders; all stakeholders part of

equation (funders, patients, regulators) 4.  Set up quantitative objectives; impact measured

against milestones as well as customary academic assessment criteria

5.  All data open access

Empowering scientists to get involved 1.  Better and broader understanding of biology

-  Reagents and tools to facilitate research (SGC) -  Deeper understanding of patient heterogeneity (ICGP)

2.  Assays that better reflect behaviour in humans -  Disease-relevant assays with clinical material (Network of

Disease Institutes)

3.  Less duplication in drug development –  Partnerships to determine efficacy of untested targets

(Open access clinical PoC)

4.  More community involvement –  Mechanisms to allow all scientists to participate in drug

discovery (BioHub; Sage Bionetworks) –  More patients involvement/understanding (Open access

clinical PoC)

Social networks to reduce waste in research Problem

$20B of funding spent on laboratory equipment/reagents. Much funding wasted on poor products. >$1B alone wasted on poor quality antibodies

Solution Create mechanism for scientists to contribute to the global knowledge

Outcome 1.  Better experiments, faster 2.  Reduced cost of research

BioHub 1.  Toronto-based company 2.  Initial focus on providing mechanism to provide

feedback on efficacy of commercial antibodies 3.  No charge for academics to comment or view

comments (like Trip Advisor) 4.  The idea is only as good as the willingness of

scientists to participate

Market size: ~$20B up for grabs

Potential opportunities for research and business

1.  Academic partnerships that deliver new targets 2.  High value clinical trials 3.  Contract research organizations with leading edge science 4.  Biotech companies with compounds and technologies

Potential impact

1.  More industry funding for University and Hospital-based research 2.  A business community built on high value service 3.  A clinical trial network that works on innovative targets 4.  Better business climate for biotech due to enhanced links with

industry

Opportunities for Ontario in the new drug discovery ecosystem
