Drug Discovery Landscape

Pharma 2020: The Vision PWC 2010

Future of drug discovery

3

‘in the next 10 years, pharma spend will continue to decrease and most of pre-clinical candidate drug discovery will be done in academia’

Dr Dave TapolczayCEO MRC Technology 2009

‘>50% of future pipeline will come from outside major pharma’

David Redfern CSO, GSK, Feb 2011

‘Research-led Pharma needs new innovative models’

John LechleiterPresident & CEO Eli LillyFeb 2011

• ‘Investors will not tolerate sub-optimal returns on R&D’

• ‘This will be the last generation of high R&D spend unless return to investors is greater’

• ‘Ten year doomsday scenario- No R&D only generics’

What future for UK science base?

4

The Future of Healthcare Industries

• Fewer and more consolidated health care companies

• Focused on developing low risk assets • Competition to in-license the ever-decreasing

number of advanced assets• Without focus, there will be a reduced supply

of innovative drugs to treat real un-met need

Between 1962 and 2000, no major classes of antibiotics were introduced

and resistance is a major issue

Why Do Drug Discovery in Academia ?

Pull: Pharma require products for their pipelines

Push: Translate publicly funded research to the clinic

Ability: Demonstrate research excellence

Moral case: Need for new approaches to diseaseReward: Potential for commercial reward and publications

Academic/ Clinical

• In-depth disease knowledge• Novel pathway knowledge• Clinical expertise & access• Innovative approaches

Industrial

• Drug discovery Know-how• Quantitative robust assays• Data security• Candidate definition

Complementary skills and capabilities

Profile of a drug candidate

Active• phenotypic activity reflecting clinical endpoint• defined target (receptor, enzyme, ion channel)

Selective• against targets associated with toxicity

Bioavailable• available at site of action • suitable elimination kinetics

Safe• Significant adverse effects only occur at higher dose than the effective

dose10

Licenseable assets

1. Candidate with human PoC or Phase I safety (IP)

2. Pre- Clinical Candidate with required safety/ toxicology/ pharmacokinetics & efficacy profile (IP)

3. Candidate molecule with defined optimised target profile

4. Lead series (+/- backup)

5. Novel target or effect

The Drug Discovery Centre (DDC)

Most academic institutions do not have capabilities or expertise to achieve this alone

However, Imperial College had the foresight to invest in creating a a Drug Discovery Centre of expertise

The DDC;• Supports the translation of research into quality drug discovery

projects

• Is a recognized leader in the developing ‘discipline’ of academic drug discovery

• Is a Cross-Faculty Centre hosted by The Faculty of Medicine, (Experimental Medicine)

13

A flexible cost efficient academic virtual biotech

• Projects sourced from Imperial’s 2000 + researchers

• Multidisciplinary expertise in-house

• Limited expensive lab capabilities

• Compound library (x1800 biologically active)

• Chemoinformatics

• Screening lab

• Outsource specific expertise, skills and capabilities from extensive world-wide array of Contract Research Organisations (CROs)

• Project and outsourcing management essential

DDC Outputs

The DDC has expertise to• Create chemical tools for basic research• Create small molecule starting points for drug discovery• Develop target biology • Develop robust bioassays to test drug candidates• Create candidate molecules

We create “Composition of Matter” patents• the starting point for Industrial Drug Development campaigns

We aim to develop new approaches to drug discovery• To shorten the 10-15 year timeframe from the bench to the clinic• Tackle the hard problems - no “low hanging fruit” left• Create the next generation of drugs

Contract studies- engaging expertise as required

• Synthetic chemistry • Peptide & protein synthesis • DMPK ~ in vitro and in vivo• Receptor/ enzyme selectivity

screens • HTS

Drug discovery linking directly to the clinic

Benefit of phenotypic human based assays

eg;• Identified compounds which reverse the

resistant phenotype in paired human platinum sensitive & resistant ovarian tumour cell lines (Hani Gabra & Euan Stronach)

• Identified compounds which effectively inhibit TNF in human rheumatoid synovial membranes using human white blood cells (Sandra Sacre, Brian Foxwell & Marc Feldmann)

Patient Access – Imperial College Healthcare NHS Trust

•One million patients pass through our London hospitals each year•Charing Cross Hospital•Hammersmith Hospital•St Mary’s Hospital•Queen Charlotte’s & Chelsea Hospital•Western Eye Hospital•Large patient population for recruitment into clinical trials•Imperial College Clinical Trials Unit - access to a large and ethnically diverse patient population in major London hospitals (2.3 million local population)
