Despite advances in pharmacology, not all patients respond favourably to drugs. A proportion of patients under therapy don't benefit from their treatment or experience an adverse reaction to the medication. However, progress in the understanding of disease mechanisms and drug actions are opening opportunities to match therapies to patient populations, and thus pave the way towards a more personalised medicine. Personalised medicine may be defined as “a medical model using molecular profiling technologies for tailoring the right therapeutic strategy for the right person at the right time, and determine the predisposition to disease at the population.
