Personalised Healthcare is essential to AstraZeneca’s approach to drug development and is adopted by more than 80% of drug products in clinical development. Selection of the right patient population using companion diagnostics is integral to the way in which AstraZeneca focuses on quality and innovation. We will discuss examples where Personalised Healthcare has transformed the delivery of new therapies to patients. We will examine how emerging diagnostic science has the potential to improve patient outcomes; including circulating tumour DNA, next generation sequencing and expanding the benefits of Personalised Healthcare across all therapy areas. Finally we will consider the role of partnerships to delivering Personalised Healthcare into clinical practice. We believe that Personalised Healthcare is the future of drug development; it epitomizes what science can do.
