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’

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

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

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

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)

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

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)
