Presentation Abstracts Session 1: Pharmacogenetics on PK/PD Wednesday 23rd November (PM) Pharmacogenetics: Expectations and Reality Geoffrey Tucker Academic Unit of Clinical Pharmacology University of Sheffield Genomic medicine has generated high expectations with regard to the advent of ‘personalised medicine’. This has been fuelled by the pace of technological advances in genotyping, enthusiasts extrapolating beyond small proof of principle and retrospective studies, and a few apparent success stories. However, drug response is a complex function of genetic, environmental and behavioural factors. Given that genetic factors need to be put into perspective, the challenge is to assemble large, prospective, multidisciplinary projects to assess the real clinical value of predictive genetic testing in drug therapy. This presentation will focus on: current evidence for the significance of genetic variation response; factors that enhance the cost- effectiveness of pharmacogenetic testing; criteria for the conduct of prospective studies to develop genetic tests of drug response; and potential constraints on implementing the ‘promise of precise prescriptions’.

Applications Of Pharmacogenomics To The Drug Discovery And Development Pipeline Duncan McHale Pfizer Limited Following the success of the late 80s and early 90s the last few years has seen rising failure rates, a marked reduction in the number of drug approvals and a sharp rise in the cost of drug development. This combined with patent expiries and external pricing pressures has led to a critical need to improve the overall survival rate of compounds and reduce the time and resources spent on compounds which will not survive. Pharmacogenomics is the application of genomic technologies to the drug discovery and development process. There is considerable expectation around this emerging science but the demonstrable value to date has been limited. Whilst the drive to develop more personalised or precise medicines is often discussed near term value to the drug portfolio is also required. Pharmacogenomics is one of the tools which can be used to help in industry’s endeavour to overcome the current challenges. Examples of where Pfizer has used pharmacogenomics to aid target choice and early decision making creating near term value will be presented.
