25 years of biologicals in IBD: What´s all the hype about?

J Intern Med 2021 Jun 15. Epub 2021 Jun 15.

University Hospital Tübingen, Tübingen, Germany.

25 years ago the field was revolutionized by the introduction of infliximab as the first hybrid anti-TNF-antibody. Subsequently, other humanized anti-TNFs were developed and marketed, followed by antibodies to new targets including integrins (vedolizumab) and interleukin (IL) 12/23 (ustekinumab). All these so-called biologicals were shown in registrational trials to induce remission superior to placebo but consistently were effective in only a minority of patients. Read More
