In the Spanish EXIT study, anti-TNF withdrawal in selected patients with IBD in clinical, endoscopic, and radiological remission had no impact on sustained clinical remission at 1 year, although objective markers of activity were higher in patients who stopped treatment.
The discontinuation of anti-TNF treatment “could be considered as an option” for a selected group of patients, said the authors led by Javier Gisbert, MD, PhD, with Autonomous University of Madrid.
However, the higher proportion of patients with elevated fecal calprotectin and significant endoscopic lesions at the end of follow-up “calls for caution and should be considered when discontinuing treatment in patients,” Gisbert and colleagues concluded.
The EXIT study results were published in the journal Gut (2025 Feb. doi: 10.1136/gutjnl-2024-333385).

Anti-TNF drugs have reshaped IBD treatment but bring infection risks and costs, prompting interest in planned withdrawal after stable remission.
Yet prior evidence has been mixed. A meta-analysis of 27 studies suggested higher relapse after stopping anti-TNF therapy. However, the results were heterogeneous and most of the studies were retrospective, with a low number of patients and without a control group to compare with.
Clinical trials that have assessed the risk for relapse after discontinuation of anti-TNF therapy generally favored maintenance but had notable limitations.
The EXIT trial was conducted at 33 IBD units across Spain. A total of 140 patients in steroid-free clinical remission for ≥ 6 months on standard-dose infliximab or adalimumab were randomized (1:1) to either continue anti-TNF or switch to placebo matched to the drug they had been taking. All patients continued on immunomodulator therapy.
At 1 year, the proportion of patients with sustained clinical remission (primary outcome) was similar between patients who continued anti-TNF therapy and peers who stopped the medication (76% and 84%, respectively).
However, the proportion of patients with significant endoscopic lesions at the end of follow-up was higher in those who withdrew anti-TNF therapy (19% vs 8.5%; P = .01). Elevated fecal calprotectin (> 250 µg/g) was more common after withdrawal (33% vs 13%; P = .01).
Fecal calprotectin > 250 µg/g at baseline predicted lower odds of sustained remission and higher risk for losing remission — and was the only factor associated with lower likelihood of sustained remission.
Common Clinical Question
“When a patient starts an advanced biologic therapy, they often ask — will I be able to stop it?” Jean-Frederic Colombel, MD, director of the Inflammatory Bowel Disease Clinical Center at the Icahn School of Medicine at Mount Sinai, New York City, who wasn’t involved in the study, told GI & Hepatology News.
Generally speaking, Colombel said he tells patients, “If the drug is working well and you are in deep remission, they should try to avoid stopping because there is a risk of relapse. And with relapse, we never know if the drug will work again and maybe we’ll have to switch to another medication.”
“It’s an individualized discussion and decision and patients who do opt to stop [anti-TNF therapy] need to be monitored closely,” Colombel said.
Colombel cautioned that the study had a relatively short 1-year follow-up and those that stopped anti-TNF therapy had evidence of recurrent inflammation.
“Even though it didn’t translate yet to clinical relapse, there were more patients with subclinical active disease in the group that stopped as compared to the group that continued,” Colombel said.
He also noted that in the SPARE trial of patients with Crohn’s disease in clinical remission, patients who stopped infliximab had a higher risk for relapse compared with patients who stopped azathioprine and those who continued the combination therapy.
The EXIT study was supported by grants from Instituto de Salud Carlos III, Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa and AbbVie. Gisbert reported serving as speaker, consultant, and advisory member for or receiving research funding from MSD, AbbVie, Pfizer, Kern Pharma, Biogen, Mylan, Takeda, Janssen, Roche, Sandoz, Celgene/Bristol Myers, Gilead/Galapagos, Lilly, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Tillotts Pharma, Chiesi, Casen Fleet, Gebro Pharma, Otsuka Pharmaceutical, Norgine and Vifor Pharma. Colombel had no relevant disclosures.
