Crohn Disease (CD)REMONONCT07564609
the REMONO-CD and the REMONO-UC Studies
An observational study of Crohn Disease (CD) and Ulcerative Colitis (UC), run by University Hospital, Clermont-Ferrand at 18 sites in France.
Trial summary
Infliximab was the first-in-class anti-TNF agent approved for treating patients with IBD, both for Crohn's disease (CD)1 and ulcerative colitis (UC)2. Infliximab is administered by intravenous infusions and demonstrated its superiority over placebo to induce and maintain steroid-free clinical remission. Read more about this study

About this study
Official title: Non-inferiority REal-world Evidence Study Comparing the Effectiveness of Subcutaneous Infliximab MONOtherapy and Subcutaneous Infliximab Combined With Immunosuppressive Therapy in Patients With Crohn's Disease and Ulcerative Colitis.
Infliximab was the first-in-class anti-TNF agent approved for treating patients with IBD, both for Crohn's disease (CD)1 and ulcerative colitis (UC)2. Infliximab is administered by intravenous infusions and demonstrated its superiority over placebo to induce and maintain steroid-free clinical remission. Besides, SONIC and SUCCESS trials showed that combination therapy (infliximab + immunosuppressant) was more effective than infliximab alone to induce clinical remission3,4. Moreover, the PANTS cohort confirmed the benefits of combination therapy to induce remission and to prevent immunogenicity over time5. Accordingly, current guidelines recommend to use infliximab in combination with an immunosuppressive therapy. Recently, subcutaneous (SC) infliximab has been developed and is now approved for patients with CD and UC6. The LIBERTY-CD and LIBERTY-UC trials showed that SC infliximab is more effective than placebo to maintain clinical remission7. Real-world evidence studies, such as the REMSWITCH program8,9, reported that switching from IV to SC infliximab is feasible, safe and well accepted leading to a low risk of relapse including in patients with intensified IV doses. In addition to its better acceptability compared to IV regimen, SC infliximab seems to have a better pharmacokinetic profile that can lead to reduced risk of immunogenicity and thus question the need for using combination therapy with SC infliximab6-9. No data enables to draw any firm conclusion on this topic10.
In the REMONO studies (REMONO-UC and REMONO-CD), we aim to show the non-inferiority of SC infliximab monotherapy to maintain steroid-free clinical remission compared to combination therapy in patients with CD and UC.
Read the detailed description
It will be a retrospective multicentre study (22 centres). Data will be collected from the electronic medical records and pseudonymized from routine clinical care between 01/01/2023 and 01/07/2025. Data will be entered the electronic CRF (RedCAP).
The main data collected at the different time points : age, disease duration, smoking status, prior bowel resection, Montreal classification (location, behaviour, extent), perianal lesions, upper GI involvement, previous IBD medications, concomitant IBD medications (including doses and intervals), disease activity (stool frequency, abdominal pain, bowel urgency, CRP level, faecal calprotectin level, endoscopic activity, MRI scores, IUS lesions), side effects, pharmacokinetics (infliximab serum level, anti-infliximab antibodies).

| REMONO CD | Patients with crohn disease | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Steroid-free clinical remission in REMONO CD
Steroid-free clinical remission (defined using PRO-2 as normal stool frequency ≤ 3 bowel movement a day and no moderate or severe abdominal pain (CDAI subscore ≥ 2)) Results will be expressed as the percentage of months (4-weeks period) spent in steroid-free clinical remission. (The statistical unit being the month and not the patient).
Measured: From 3 months up to 1 year after the start of treatment
Steroid-free clinical remission in REMONO UC
Steroid-free symptomatic remission (defined using PRO-2 as normal stool frequency and no rectal bleeding) Results will be expressed as the percentage of months (4-weeks period) spent in steroid-free clinical remission. (The statistical unit being the month and not the patient).
Measured: From 3 months up to 1 year after the start of treatment
