DOCTIS Project

Decision on optimal combinatorial Therapies in IMIDS using Systems Approaches. Immune-mediated Inflammatory Diseases (IMIDs) are a group of diseases caused by inappropriate activation of the immune system in cells and organs. They are relatively common and affect up to 7% of the general population, being the third most common type of disease in developed countries. In the DoCTIS project, we focus on six of the most frequent IMIDs in our society: rheumatoid arthritis, psoriasis, psoriatic arthritis, Crohn’s disease, ulcerative colitis and systemic lupus erythematosus. In these six diseases, chronic activation of the powerful immune system ultimately affects the functionality of many tissues and organs. This clearly reduces the quality of life of many patients, as well as increases the risk of other diseases and shortens life expectancy. The last 20 years have seen a breakthrough in the development of therapies to treat IMIDs. These therapies have been an improvement over previous drugs, helping reduce the impact on a significant percentage of patients. However, many other patients do not respond adequately to these new therapies. Moreover, in many cases, these new therapies eventually lose efficacy and must be discontinued. These therapies are expensive and have become a major burden on European healthcare systems. The DoCTIS project is designed to address this major health problem in IMIDs. To do this, we will identify new combinations of existing drugs that enhance the effect of each other. This combinatorial effect will have many beneficial aspects for IMID patients: it will reduce disease activity to remission (i.e. no symptoms), it will reduce the dose of the drugs (and thus the risk of toxicity) and, finally, it will reduce the likelihood of becoming resistant to therapy. The DoCTIS project has received funding from the European Union’s H2020 reearch and innovation program.
