This guidance updates and replaces NICE technology appraisal guidance 40 (published in April 2002).

The review and re-appraisal of infliximab for the treatment of severe active or active fistulising Crohn’s disease has resulted in a change in the guidance. Specifically, infliximab should now be given as a planned course of treatment until treatment failure (including the need for surgery) or for 12 months, whichever is shorter. Treatment should then only be continued if there is clear evidence of ongoing active disease. Adalimumab is now also recommended as another treatment option for people with severe active Crohn’s disease.

Your responsibility

The recommendations in this guidance represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, health professionals are expected to take this guidance fully into account, alongside the individual needs, preferences and values of their patients. The application of the recommendations in this guidance is at the discretion of health professionals and their individual patients and do not override the responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or their carer or guardian.

Commissioners and/or providers have a responsibility to provide the funding required to enable the guidance to be applied when individual health professionals and their patients wish to use it, in accordance with the NHS Constitution. They should do so in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities.
