Abstract: The invention describes the method allowing for efficient predictive ranking of clinical efficiencies of the existing targeted medicinal products for individual patient with proliferative or oncology disease. The method makes it possible to use a wide range of experimental data received from the patients' pathological tissue samples and relevant control samples: information on gene mutations, transcription factor binding profile, protein (considering harmonization), mRNA (considering harmonization) and microRNA expression strength. The method also uses information on molecular targets of the medicinal products. This method can be automated to prevent potential errors associated with manual calculation and makes it possible to consider patient-specific changes in hundreds and thousands molecular pathways which include tens and hundreds of gene products. This method also considers the features and mode of action of various classes of target drugs.
