The immune-modifying agents are step III drugs and are used if corticosteroids fail or are required for prolonged periods. Anti-TNF monoclonal antibody therapies are also step III drugs that are effective in both Crohn disease and ulcerative colitis; some studies have demonstrated that they have a greater efficacy than azathioprine. Traditionally, anti-TNF agents have been administered when Crohn disease has been unresponsive to steroids and immunosuppressants; however, the early introduction of these agents in conjunction with immunosuppressants in those with an increased risk of a complicated, severe, or possibly aggressive IBD has the potential to modify the disease course.
