RCT looking at withdrawal of infliximab or immunomodulator, in patients on combination therapy and in remission for atleast 6 months - 211 patients randomized in 7 countries (Australia / Nordic countries, UK, France) to either continuing both, stopping infliximab or stopping immunomodulator - Patients with fistulising disease, or severe reaction to infliximab were excluded. Risk of relapse at 2 years: Combination therapy: 14% Ifx stopped = 36% immunomodulator stopped = 10% Nearly all patients who relapsed on Ifx withdrawal were promptly re-captured by starting Ifx Stopping Ifx in patients with CD on combination therapy results in an excess 21% increase in risk of relapse. No increase risk of relapse in stopping immunomodulator after stable remission has been achieved.
