Clinical trials

ReCOUP is a multicenter clinical study designed to evaluate the efficacy of upadacitinib (Rinvoq®) in patients with ulcerative colitis whose disease has become active again despite maintenance treatment with upadacitinib 30 mg. This study involves adult patients aged 18 to 64 years with active ulcerative colitis, who are being treated with upadacitinib and are not participating in another interventional clinical trial. Participation in this study will depend on the patients' response to treatment during the 52-week maintenance period. Several follow-up visits will be scheduled throughout the study according to a timetable defined by the protocol, and additional visits may be arranged if necessary depending on patients' health status.

Inflammatory Bowel Disease (IBD) patients have an increased risk of ColoRectal Cancer (CRC). The cumulative risk of CRC development is estimated at 1% after 10 years of disease progression, 2% after 20 years, and 5% after more than 20 years of disease progression (1). The incidence of CRC in IBD has gradually declined, attributed to enhanced detection of preneoplastic lesions (dysplasia), improved adherence to screening recommendations, utilization of advanced high-definition endoscopes (2-4), and the implementation of more efficacious therapeutic strategies (5-9). Presently, there is no consensus on the endoscopic management of dysplastic lesions. Recent techniques such as submucosal dissection (ESD) enable the resection of non-polypoid flat lesions larger than 2 cm. Lesions previously treated with colectomy can now be resected by ESD with en-bloc resection rates of approximately 85.7% (17). However, long-term data on the risk of local or distant recurrence after endoscopic resection in IBD is lacking. It is crucial to evaluate complete (R0) and curative resection rates, as well as the rate of local recurrence, based on the type of endoscopic treatment. In light of the 21st century advancements, characterized by high-definition endoscopes and targeted treatments, it is imperative to: * Assess the prevalence and incidence of dysplasia in IBD and its risk of progression to CRC. * Specifically characterize the endoscopy and histology of pre-neoplastic lesions in IBD to facilitate better selection of lesions amenable to endoscopic treatment or surgery. * Evaluate the rates of local and distant recurrence over time, considering factors associated with this evolving risk (IBD characteristics, endoscopic appearance, histology, type of resection, etc.).

Crohn's disease (CD) is a chronic and destructive inflammatory disease of the gastrointestinal tract characterized by phases of relapse and remission. Tumor necrosis factor (TNF) antagonists, anti-integrins and anti-interleukin (IL) 12/23 are the main therapeutic agents to obtain deep remission and prevent disability. Despite the significant advances these biologics represent in treating inflammatory bowel disease (IBD), many patients experience suboptimal responses, including primary non-response or a loss of effectiveness over time, often leading to treatment discontinuation. For all these medications, a dose-response relationship has been demonstrated and an increase in dose or dosing frequency is recommended. Dose escalation is now an essential therapeutic approach necessary in 30 to 50% of CD patients treated with biologics. This strategy, supported by international guidelines, allows for long-term efficacy to be maintained without compromising safety. Guselkumab (GUS) is a monoclonal antibody targeting the p19 subunit of IL-23. In a recent phase III trial (GALAXI), GUS demonstrated superiority of both subcutaneous (SC) maintenance doses (200 mg every 4 weeks \[q4w\] and 100 mg every 8 weeks \[q8w\]) compared to placebo and ustekinumab. In the GALAXI phase III program, at least 30% of patients did not achieve clinical response after a 12-week intravenous induction, and almost 20% experienced a loss of response by week 44. In these patients, the benefit of an intensified dose of GUS (200 mg q4w) maintenance remains to be determined to guide clinicians in optimizing its use in clinical practice. The investigator aimed to evaluate the one-year effectiveness of GUS in CD in real-world settings and under optimal conditions allowing dose intensification.

Efficacy of Mirikizumab to achieve transmural healing in patients with Crohn's Disease

Telemonitoring is of definite theoretical interest for patients suffering from chronic diseases and could help to improve monitoring of treatment efficacy and tolerance, and hence remission and quality of life. Reimbursement is now planned in France for devices that have demonstrated a positive effect on patient intake. However, available studies testing different tools in IBD have shown no significant improvement in disease control or quality of life. Nevertheless, major secondary endpoints such as reduced hospitalization, complications and healthcare costs have been demonstrated. Several biases have been identified to explain these disappointing results, such as the heterogeneity of the tools/applications tested, methodological limitations concerning the main objective and technological limitations of the tools evaluated. We propose here to evaluate the impact of a tight remote monitoring through digital tool on disease control, in patients with active IBD, thanks to the MedicWise platform. The technology of the MedicWise solution enables the automatic collection of a wide range of biological and healthcare consumption data, thus limiting the need for patient input. MedicWise has obtained the CE label and is already used and reimbursed in France in other chronic diseases. The SECURITY trial proposes to evaluate the impact of a tight remote monitoring through digital tool on time spent in remission. Improvement of IBD related disability is also a major secondary objective of the study. It also has the following secondary objectives to analyze the impact of this tool on the organization of care teams caring for patients with IBD.

This is a French prospective longitudinal observational multicentre cohort study. Primary objective : to assess prospectively the presence and the extent of safety concerns (cancer, serious infections, arterial and venous thrombotic events) in patients with CD and UC and treated with JAKi, anti-IL23p19, and S1p modulators.

Multicenter prospective cross-sectional study of CD patients, its aim is the construction of an objective and reproducible system for evaluation of Transmural healing in Crohn's Disease (CD). Primary objective : Objective definition of depth or grade of transmural healing in relation to radiologic signs observed during Magnetic Resonance Enterography (MRE) in CD

PHASE: IV DESCRIPTIVE: Randomized, interventional, open label multicenter trial POPULATION: Moderate to severe ulcerative colitis STUDY TREATMENTS: Patients will all receive Adalimumab 160/80/40mg EOW until V1 (W14) followed by 40mg EOW until V2 (W26) and could be optimized up to 80mg EOW (or 40 EW according to patient and/or investigator preference) for two months and then could be optimized up to 80mg EOW (or 40 EW according to patient and/or investigator preference) and azathioprine (2.0/2.5 mg/kg/ day) or methotrexate (25 mg EW) until V3 (W 38). OBJECTIVES: To assess the impact of a treat to target treatment follow up by e-Monitoring and fecal calprotectin dosing at home associated to an appropriate patient education versus standard treatment follow up at W48 in patients requiring a treatment with adalimumab (Humira®).
