Efficacy and Safety of CDED With Anti-TNF-α Biologics in Crohn's Disease

Crohn's disease (CD) is a chronic inflammatory bowel disease with high recurrence and surgical rates. Mucosal healing is a key therapeutic goal, yet current anti-TNF-α biologics achieve only about 30% mucosal healing. Dietary intervention, particularly the Crohn's Disease Exclusion Diet (CDED), shows promise in CD management. Preliminary data suggest that combining CDED with anti-TNF-α biologics may significantly improve mucosal healing rates (42.9% vs 25%). This single-center, prospective, randomized, controlled trial will enroll 185 adult CD patients with active disease (SES-CD ≥3), randomly assigned 1:1 to receive either anti-TNF-α biologics plus CDED or anti-TNF-α biologics alone. The primary endpoint is mucosal healing rate at week 14 (SES-CD=0). Secondary endpoints include clinical remission, endoscopic response, transmural healing, and adverse events. This study aims to provide high-quality evidence for the efficacy and safety of this combined approach in Chinese CD patients.

Surgery vs Biologics for Treating Stricturing CD--a RCT

The management of stricturing Crohn's disease (CD) remains challenging. Although surgical resection may be the final way to solve it, the efficacy of biologics for symptomatic CD associated strictures was acceptable. In clinical practice, the chioce of treatment is particularly difficult. Therefore, a clinical trial of biologics versus surgery is needed to assess which one is prefered.

ENROLLING BY INVITATION

NCT06424769

Improving Outcomes and Reducing Disparities for Patients With Inflammatory Bowel Disease Through Epidemiology and Enhanced Disease Management

The goal of this clinical trial is to learn whether IBD patients have better disease outcomes and feel more empowered to manage their condition if they have access to text messaging with their clinical team and if their symptoms are more regularly monitored through text-based surveys. Researchers will compare participants who have access to text-based monitoring, communication and education to participants who have access to text-based education alone. Researchers will also examine if different social and other non-medical factors impact IBD symptoms and quality of life. All participants will: * complete 5 brief on-line surveys over 12 months about their IBD and social risk factors, * receive IBD education content by text message up to 2 times a week. Some participants will also: * receive additional surveys by text to monitor their IBD progression, * have the opportunity to directly text message their IBD medical team.

Partial Enteral Nutrition to Prevent Weight Loss and Sarcopenia in IBD Patients at Nutritional Risk - SIMBA

This is a multicenter, open-label, randomized two-arm interventional nutritional study evaluating the effects of partial enteral nutrition (LH VIOLA) in patients with Inflammatory Bowel Disease (IBD) at risk of malnutrition. A total of 146 patients (73 per arm) will be enrolled across 4 centers. IBD, including Crohn's Disease and Ulcerative Colitis, is associated with malabsorption, weight loss, sarcopenia, and malnutrition, which negatively impact quality of life and treatment outcomes. Nutritional assessment using the Malnutrition Universal Screening Tool (MUST) will identify patients at risk. Participants will be randomized to receive either nutritional counseling alone or counseling plus oral LH VIOLA supplementation (≥412 kcal/day) for 16 weeks. The primary objective is to evaluate maintenance or recovery of body weight at 16 weeks. Secondary objectives include assessment of weight at 24 weeks, muscle strength (handgrip), body composition and metabolic parameters (BIA/BIVA, vitamin B12/D, pre-albumin), quality of life (SF-12), economic impact, adherence, gastrointestinal tolerability, and reduction in malnutrition risk (MUST score). The study duration per patient is 24 weeks (16 weeks of intervention plus 8 weeks follow-up), with a total study duration of 18 months. The sample size is powered to detect an increase from 40% to 65% in patients achieving weight maintenance or gain at 16 weeks, accounting for a 15% dropout rate.

The French E3N Prospective Cohort Study

The French E3N cohort was initiated in 1990 to investigate the risk factors associated with cancer and other major non-communicable diseases in women. The participants were insured through a national health system that primarily covered teachers, and were enrolled from 1990 after returning baseline self-administered questionnaires and providing informed consent. The cohort comprised nearly 100 000 women with baseline ages ranging from 40 to 65 years. Follow-up questionnaires were sent approximately every 2-3 years after the baseline and addressed general and lifestyle characteristics together with medical events (cancer, cardiovascular diseases, diabetes, depression, fractures and asthma, among others). The follow-up questionnaire response rate remained stable at approximately 80%. A biological material bank was generated and included blood samples collected from 25 000 women and saliva samples from an additional 47 000 women. Ageing among the E3N cohort provided the opportunity to investigate factors related to agerelated diseases and conditions as well as disease survival.

Gastro-intestinal Biopotential Recorder by Means of Surface ELEctrodes

The goal of this clinical trial is to compare the gastro-intestinal biopotentials recorded with a homemade device using surface electrodes placed on the abdomen in healthy volunteers, Crohn's disease patients without fibrosis, Crohn's disease patients with fibrosis and in functional gastrointestinal disorders (FGID) patients. The main question it aims to answer is: • Is there any differences in the gastro-intestinal biopotentials between the different populations under study? It aims to answer two secondary questions: * Are the gastro-intestinal biopotentials comparable to the Harvey-Bradshaw Index, MRI and biological data for patients with Crohn's disease? * Are the gastro-intestinal biopotentials comparable to Rome IV criteria for functional gastrointestinal disorders patients? Participants will undertake two recordings made with the device. The first one will last 1 hour and 30 minutes and will occurs while the participants are fasting. Then, the participants will eat a standardized meal. Finally, the second recording will take place after the meal ingestion and will last 1 hour and 30 minutes while the participants are in postprandial state.

Study on the Treatment of Anal Fistulas Using Alofisel Versus Fat Autologous Stem Cells

One of the newest and most innovative medicinal approaches is cell therapy. Several clinical trials and experimental investigations have looked into the feasibility of treating CD-related fistulas with stem cells. The current indication for ALOFISEL® (active ingredient: Darvadstrocel) is the treatment of difficult perianal Crohn's fistulas that have not responded well to at least one conventional therapy or biotherapy. This brand-new cell therapy medication is created using amplified allogeneic human adult mesenchymal stem cells from adipose tissue (ADSC). The supplier mandates that two patients be booked for a single dose of ALOFISEL® due to the medication's expensive price-roughly €54,000 for a single dose of 120 million-which cannot be stored once thawed. Only one of the two patients receives therapy; the other serves as the backup patient. By doing this, another "back-up" patient who might receive no care at all is avoided. An developing alternate approach to allogeneic ADSC injection for the treatment of complicated anal fistulas in CD is autologous fat injection. In recent years, autologous fat grafts have been the subject of in-depth research. They are popular because it is simple to get clinical samples (lipoaspirate, adipose tissue), and because there are a lot of ADSCs in adipose tissue. Additionally, ADSCs show strong immunomodulatory and regenerative capacities. We would wish to compare the effectiveness of these two injection kinds on perianal fistulas as part of our care of CD.
