Biomarkers for assessing the response status for treatment of inflammatory condition or disease affecting the digestive tract such as inflammatory bowel disease in human patients

Abstract

The invention relates to the identification of biomarkers of the response status of a patient for a treatment with anti-TN-Falpha agents, for treatment with anti-α4β7 agents or with both anti-TNFalpha agent and anti-α4β7 agents and to their use in assessing such status, in particular for assessing nonresponsive status for a treatment with anti-TNFalpha agents or respectively with anti-α4β7 agent in human patients suffering from inflammatory condition or disease, in particular Inflammatory Bowel Disease (IBD), in particular Ulcerative Colitis or Crohn's disease. The invention describes a method of in vitro assessing whether a treatment with anti-TNFalpha agent or with anti-α4β7 agent may be useful in a human patient suffering from inflammatory condition or disease, in particular when said condition or disease is a chronic and/or relapsing one, particularly a gastrointestinal, more particularly intestinal, inflammatory condition or disease which is eligible for treatment with anti-TNFalpha agent or respectively with anti-α4β7 agent. In a specific embodiment the method is suitable to assess whether such patient would be non-responsive to treatment with such anti-TNFalpha agent or respectively with anti-α4β7 agent and comprising determining a molecular signature in a biological sample previously obtained from said human patient.
