W hy biom arkers?

Individual’s response to medicines is variable and complex

  • I ntrinsic factors (e.g. age, health status, genetics)
  • Extrinsic factors (such as diet, the use of concomitant drugs,

exposure to sunshine etc.)

  • I nterplay of factors 1 , 2 + characteristics of the m edicine

A growing variety of BMs, most often panels of them, measured with modern technologies allowing all of us

  • to augment precision in the judgment necessary for selecting the medicine and

course of action appropriate for each person

  • to better understand health, risk factors and mechanisms of diseases

  • Individual’s susceptibility to disease, clinical onset and progression
  • Individual’s susceptibility to Adverse Drugs Reactions (influenced by genes* )
  • Individual’s mechanisms for drug’s Absorption, Distribution, Metabolism (transformation)

and Elimination in the body (ADME–Pharmaco Kinetic - PK) (influenced by genes* ).

  • Individual’s disease characteristics and medicines’ mode of action: Medicines bind

/ interact with various components in the body called targets and from this interaction pathways are activated: this is about the Mechanism of Action of the medicine and its Pharmaco Dynamics (PD influenced by genes* ) * Genes influence depends on a number of characteristics and include: penetrance, alleles status,

epigenetic (including influence of other drugs/ environment) …

  • 3 0 – 5 0 % of all clinically used drugs are metabolised by functionally polymorphic

enzymes (phase I and phase II)

  • plasma levels of some drugs at the same dosage can vary 5 -2 0 -fold among individuals

by e.g. excessive prodrug activation  Guidelines on genom ics BM in drug developm ent ( phase I -I I I )

Figure 2 : Num ber of m edicinal products and ratio of m edicinal products containing a genom ic biom arker ( gene) in their product label under “Therapeutic I ndication” per year. The num ber of pharm acogenom ic biom arker in EU product label have been steady betw een 1 9 9 9 and 2 0 1 0 and since then gradually increasing in recent years. I nitially, they have been intended for inform ation only, progressing into becom ing one of the im portant determ inant for selection of patients likely to benefit from treatm ent and “m ore” individualised dose selection. Biom arker inform ation m ay also be included in the labelling in case of negative selection ( i.e., if the biom arker is used to select a population unlikely to respond) or in case of uncertainty about the value of the biom arker but w here a negative selection is suspected, e.g. vandetanib.

  • The occurrence of rare but serious ADRs or lack of efficacy/ effectiveness have often

been identified late in drug development phase or long after drug approval

  • Lim ited inform ation available on the utilisation of a genom ic biom arker during follow

up (post m arketing) or on the effect of labelling with genomic information.

  • Guidelines have been adopted for the evaluation of genom ic influences during

Pharm acovigilance activities in order to inform and improve clinical use of specific treatments. Collection and storage of genom ic m aterial ( e.g. DNA or other)

– during clinical trials and – up on the occurrence of serious ADRs, lack of effectiveness post authorisation or unexpected worsening of the condition

Take aw ay m essages

  • Biomarkers are measured with modern technologies (e.g. genomics, digital tools): useful to better develop

medicines and personalise care adding precision to the clinical judgment about which medicines an individual may either benefit from and how (e.g. dose) or should avoid

  • BM are measurements that may be requested by the regulatory authorities or proposed by sponsors for

medicines in clinical development and use

  • The potential of data generated on biomarkers is well beyond the medicines themselves: personalised,

participatory, preventive, predictive and patient centred health care

  • The BM samples and data:
  • contributions from patients groups with discussion and participation in shaping the informed consent principles a key

document with statements on the reason for taking samples/ measurements, the planned and future use of the samples and data, the measure for data privacy protection, the description of interactions and communication on both expected and unexpected findings

  • Yourself: Have your interpreted results with you for the future (https: / / www.pharmgkb.org/ ): clinically relevant
  • Yourself: Know in which biobank/ database your “sample” is and for how long : help the system to evolve
