Steroid-Free Deep Remission at One Year Does Not Prevent Crohn's Disease Progression: Long-Term Data From the TAILORIX Trial.

BACKGROUND & AIMS: Crohn's disease (CD) patients included in the Tailored Treatment With Infliximab for Active Crohn's Disease (TAILORIX) trial started infliximab in combination with an immunosuppressant for 1 year. The aim of the present study was to determine the long-term disease course beyond the study period. METHODS: We compared the outcomes of patients who did or did not reach the primary end point of the TAILORIX trial, defined as sustained corticosteroid-free clinical remission from weeks 22 through 54, with no ulcers on ileocolonoscopy at week 54. The primary outcome of this follow-up study was the progression-free survival of CD defined by anal or major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. RESULTS: The 95 patients (median disease duration, 4.5 mo; interquartile range, 1.0-56.6 mo) analyzed, including 45 (47%) who achieved the primary end point, were followed up for a median duration of 64.2 months (interquartile range, 57.6-69.9 mo) after the end of the study period. There was no significant difference in CD progression-free survival at 1, 3, and 5 years between patients who achieved the TAILORIX primary end point and patients who did not (P = .64). No difference was observed between both groups for each component of CD progression: anal surgery, major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. CONCLUSIONS: Achieving a sustained clinical remission off steroids with complete endoscopic remission in this cohort of 95 patients with early CD was not associated with less disease progression. Prospective trials to define the therapeutic goals that change the natural history of CD and prevent complications are needed.

No Superiority of Tacrolimus Suppositories vs Beclomethasone Suppositories in a Randomized Trial of Patients With Refractory Ulcerative Proctitis.

BACKGROUND & AIMS: Ulcerative proctitis (UP) refractory to 5-aminosalicylic acid (5-ASA) suppositories is a challenge to treat, often requiring step up to immunomodulator or biological therapy. Topical tacrolimus is effective and safe in patients with refractory UP. However, it is not clear how tacrolimus suppositories fit into in the treatment algorithm of UP. METHODS: We performed a randomized controlled, double-blind study at 8 hospitals in the Netherlands and Belgium from 2014 through 2017. Eighty-five patients with refractory UP (65% women) were randomly assigned to groups given once daily tacrolimus suppositories (2 mg; n = 43) or beclomethasone (3 mg; n = 42) for 4 weeks. The primary outcome was clinical response (decrease in Mayo score of 3 or more). Secondary outcomes included clinical remission, endoscopic response and remission, adverse events and quality of life. Outcomes were compared using Fisher's exact test and Mann-Whitney U test. RESULTS: Proportions of patients with clinical responses were 63% in the tacrolimus group and 59% in the beclomethasone group (P = .812); proportions of patients in clinical remission were 46% and 38%, respectively (P = .638). Proportions of patients with an endoscopic response were 68% and 60% in the tacrolimus group and in the beclomethasone group (P = .636); proportions in endoscopic remission rates were 30% and 13%, respectively (P = .092) Median increases in the inflammatory bowel disease questionnaire score were 18.0 in the tacrolimus group and 20.5 in the beclomethasone group (P = .395). Adverse event rates did not differ significantly between groups. CONCLUSIONS: In a 4-week randomized controlled trial, tacrolimus and beclomethasone suppositories induce comparable clinical and endoscopic responses in patients with UP refractory to 5-ASA. There were no significant differences in adverse events rates. Tacrolimus and beclomethasone suppositories are therefore each safe and effective treatment options for 5-ASA refractory disease.
