System of Personalized Medicine Applied to Health Services - MedeA

The selection of a specific drug for pharmacological prescription in the context of medical therapeutics has traditionally been carried out on the basis of trial and error. However, the information available to increase the effectiveness and prevent adverse drug reactions (hereinafter ADR) is increasing every day.

The sources of this information can be found in the product’s technical data sheet (summary of product characteristics (SmPC) authorized by the Spanish Agency for Medicines and Health Products (hereinafter AEMPS) or the European Medicines Agency (hereinafter the EMA). Additionally, there is scientific information available as well as the recommendations of various consortiums and scientific societies. There is clinical information such as the physiopathological conditions that determine the prescription, but also biomarkers, each time in a more important way.

At present, more than one third of EMA SmPCs contain a genetic biomarker, with different relevance levels in their recommendation of clinical implementation.
Among the useful information to increase the efficiency of pharmacological prescription are several factors: Clinical (personal, family background of drug response and adverse drug reactions and the physiopathology of the disease), Clinically relevant pharmacological interactions (drug / food / medicinal plants interactions, etc.); plasma levels of drugs and metabolites, genetic and other biochemical biomarkers (physiological and physiopathological), clinical routine analytical data (biochemistry/hematology/microbiology, etc.), and genetic biomarkers; in addition to others to be potentially taken into account (eg the microbiome).

Although some of this information is available in the electronic medical record, its management is done manually, therefore a guided drug prescription tool that allows a rapid increase in the choice of drug in a context of polytherapy and multiple pathology is required, as recommended by the National Strategy proposed by the Spanish Senate. On the one hand, it is necessary to generate software that integrates it, on the other hand to produce the necessary information (e.g. pharmacogenetic biomarkers to position it in the digital clinical medical record). This system must be evaluated to establish a cost/effectiveness analysis that allows decision-making regarding its implementation in the National Health Service.

General Introduction of MEDEA project strategic line

  1. Personalized medicine and variability in the response to drugs. Although the personalization of medicine and therefore of pharmacological therapy exists from the very beginning of therapeutics being its essence, at present the enormous information generated by the development of pharmacogenetics and pharmacogenomics, the accessibility of genetic information, together with the development every day of computer tools capable of handling a greater amount of information make it a reality to try to objectify the numerous variables that determine the variability in the response to drugs. Therefore, a scenario has been generated in which it is feasible the objectification of the empirical variables that have enabled the personalization of pharmacological treatment. On the other hand, objectification supports the personalization of the therapeutic guideline, which is of special relevance from the drug regulatory point of view.
  2. Contribution to the Sustainability of health services. The objectification of empirical observation and its potential use in electronic clinical background environments is one of the strategies for the reduction of variability in the response to drugs, specifically adverse reactions and therapeutic failures. This strategy can contribute in a decisive way to the sustainability of health systems, by reducing the indirect costs due to the failure of pharmacological therapy(i.e. ADR), mainly from the development of preventive strategies. This would be the basis for the development of a Personalized Medicine Program for the individualization of pharmacological therapy.
  3. Barriers to overcome for its implementation. Although the necessity of the generalized application of Personalized or Precision Medicine has been proclaimed, for example, in the recent general document of the Senate on National Strategy of Genomic, Personalized and Precision Medicine for the National Health System, there are still barriers to extend its implementation, specifically to public health services. These include, on the one hand, the exclusive use of genetics, without including other relevant physiological or environmental variables (or other type of biomarkers) of relevance in the variability in the response to drugs and, on the other hand, the lack of computer applications that simplify the prescriber’s decision-making in healthcare. There is an additional problem most of the applications are focused on a single drug, although the problem lies in selecting the prescription during polymedication in multi-pathology. In summary, the main barrier detected for the implementation of personalized drug prescription based on the available objective information is the lack of a system that allows the selection of individual treatment in a pharmacological politherapy situation (interactions are a crucial factor) objectifying the genetic variability together with other factors of relevance for drug response and ADR. 
  4. The technological challenge: Development of a Personalized Drug Prescription System. The individualization of the prescription based on the objectification of multiple determinants of the variability in the response to drugs, depends on information partially existing in the Electronic Medical Record (a, b, c) and other new generation (c, d, e). Namely:a) clinical information: (personal and family background, codification at discharge, background of previous prescriptions-failures or successes, physiopathological states: pregnancy, lactation, renal failure, liver disease, etc.), information on life habits- consumption of tobacco, alcohol, etc.;
    b) outine analytical data – hematology, biochemistry, urine.
    c) pharmacogenetic factors;
    d) other relevant data: plasma levels of drugs, etc.
    e) nteractions clinically relevant.

    Once the system is built, there is a second challenge that is its implementation in terms of public health services for both assistance and clinical research.
    In summary, it is intended to have a drug prescription system that allows real-time consultation in the electronic clinical background of pharmacogenetic variables and other determinants in the choice of a drug, mainly contained in the Clinical Guidelines or at least in the drug regulatory level.

  5. Needs to be solved: the choice of drug at adequate doses, based on pharmacogenetic and other analytical biomarkers, according to the particular conditions of each patient (consumption of other drugs, clinical and physiopathological situation), in order to prevent ADR and therapeutic failures, decreasing costs of health services as a last resort. Additionally, to provide a tool for the personalized intelligent selection of individuals in clinical studies with drugs. 
  6. Subprojects. Next, the different components of the system to build into different Technological Challenges are exposed, in such a way that, once integrated, they generate a prescription system that allows the necessary consultations and supports in the decision making, offering the possible alternatives in a concrete situation. The Innovative Public Procurement (CPI) to be executed in the MEDEA project is broken down into 4 Subprojects (technological demand, one Technological Challenge for each of them).
