Introduction

Pre-emptive medicine is a new paradigm shift in medicine, being the ultimate individualized medicine approach that prevents or delays disease onset by predicting and diagnosing disease onset with high accuracy at an earlier stage (hereinafter ‘unhealthy’) and implementing therapeutic intervention before disease onset. It is a dream-like concept to diagnose the degree of ill-health of an individual using new diagnostic technologies (pre-emptive diagnosis) and take appropriate measures to prevent illnesses before they occur. In the field of advanced diagnostic system development, we are developing diagnostic agents for lifestyle-related diseases, such as cancer, and mental disorders, such as depression, to achieve pre-emptive medicine. Furthermore, recently, many drugs for autoimmune diseases, such as cancer and rheumatoid arthritis, have been developed, which are effective in curing these diseases. However, the drug prices are high, and the cost of treatment can be tens of millions of yen per patient. Unfortunately, drugs are not always effective. Therefore, we aim to develop a diagnostic technology that predicts drug efficacy and side effects before drug administration through an industry–academia collaboration and pre-emptive diagnostic technology to develop diagnostic drugs that will attract global attention.
