Global IBD Visualization of Epidemiology Studies (GIVES) in the 21st Century

GIVES-21
Start date: October 1, 2021
Phase:
Study type: Observational

Crohn's disease (CD) and Ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) of unknown etiology. The pathophysiology of IBD relates to the mucosal immune response to antigenic stimulation from the gut microbiota secondary to environmental influence, on a background of genetic susceptibility. IBD represents an important public health problem because it affects mostly young people at an age when they are most active in their private and professional life, and a management challenge because of its unpredictable relapsing nature. During the last few decades the incidence of IBD has changed in many ways. Incidence rates of traditionally high incidence areas such as the United States and Europe is remaining relatively stable or even decreasing, while the diseases have become more prevalent in previously low incidence areas, including Asia. Our latest systematic review has demonstrated that the highest reported prevalence of IBD was still in Europe and North America, however, the incidence of IBD has been rising in newly industrialized countries since 1990.

Impact of Anti-TNF, Vedolizumab and Tofacitinib on Aortic Stiffness, Carotid Intima-media Thickness and Cardiovascular Risk of Patients With Ulcerative Colitis

VASC-UC
Start date: February 2, 2021
Phase: N/A
Study type: Interventional

An increased risk of cardiovascular (CV) diseases has been observed in patients with inflammatory bowel diseases (IBD). The impact of IBD drugs, such as anti-TNF, anti-integrins or anti-JAK, on the risk of CV events in IBD is remains unknown. Aortic pulse wave velocity (aPWV), a measure of aortic stiffness, and carotid intima media thickness (CIMT) are both predictors of cardiovascular events and are increased in patients with IBD. The investigators aimed to prospectively compare the CV risk, CIMT, arterial stiffness and biomarkers of endothelial dysfunction at baseline and after 3 and 12 months of anti-TNF, vedolizumab and tofacitinib.

A Study of Intravenous Vedolizumab Administered Every 4 Weeks in Japanese Participants With Moderate to Severe Ulcerative Colitis or Crohn's Disease

Start date: June 4, 2021
Phase: Phase 3
Study type: Interventional

The main aim of the study is to learn if 4-weekly vedolizumab improves symptoms of Japanese participants with moderate to severe ulcerative colitis (UC) or Crohn's disease (CD). Vedolizumab is commercially available in Japan for 8-weekly treatment but not for 4-weekly treatment. The study doctors will also monitor side effects from the study treatment. This study will take place in Japan. At the first visit, the study doctor will check if each person can take part. For those who can take part, participants will receive vedolizumab intravenously once every 4 weeks. After 3 infusions of vedolizumab (which will be 12 weeks of treatment), the study doctor will assess if symptoms of the participants have improved. Participants who do not have improved symptoms after 12 weeks of treatment with vedolizumab will stop this treatment. Then, they will visit the study clinic 16 weeks after their last infusion of vedolizumab for a final check-up. Participants who have improved symptoms after 12 weeks of treatment with vedolizumab will continue to receive vedolizumab every 4 weeks. Then, after their last infusion of vedolizumab, the participants will visit the study clinic 16 weeks later for a final check-up. Finally, the study clinic will make a phone call to each participant 6 months after their last infusion to check if they have any health problems.

Comparison of Functional Outcomes Between Transanal and Laparoscopic vs Open Ileal Pouch-Anal Anastomosis

FUNCTIon
Start date: January 1, 2021
Phase: N/A
Study type: Interventional

Background: Ulcerative colitis (UC) and inflammatory bowel unclassified (IBDu) are inflammatory bowel diseases (IBD) involving the colon and rectum. It is a chronic disease occurring in young people with a high burden on social and professional life. Although treated medically by immunomodulatory drugs, about 15 - 20% of UC patients will need an ileal pouch-anal anastomosis (IPAA). In primary cases, this procedure is usually performed laparoscopically (further called transabdominal IPAA or tabd-IPAA). More recently even less invasive surgical techniques have emerged, using a trans-anal access, facilitating dissection of the distal rectum. Although transanal access is associated with a good postoperative outcome profile, there is very limited data on functional outcome in patients with a trans-anal ileal pouch-anal anastomosis surgery (ta-IPAA). Objective: The objective of this study is to determine if functional outcome following ta-IPAA is the same as or better than postoperative function after tabd-IPAA with UC and IBDu. Study design: The FUNCTIon trial is a non-inferiority randomized, controlled trial that will involve 3 hospitals across North-America and Europe. Patient population: All patients with UC and IBDu eligible for pelvic pouch procedure will be randomized to either ta-IPAA or tabd-IPAA. Prior to the start of the study REB will be obtained at all centres and informed consent will be obtained from all patients. The inclusion criteria for the study are: patients between 18 and 60 years old with UC or IBD unclassified (IBDu) eligible for surgery. They will need to speak either English or the primary language of the center they are treated at. The exclusion criteria for the study are: contraindication for laparoscopy, familial adenomatous polyposis (FAP), colorectal cancer, presence of primary sclerosing cholangitis (PSC), a hand-sewn ileo-anal anastomosis, immunomodulating therapy including steroids, pregnancy and lactating, urgent indication. Intervention: ta-IPAA or tabd-IPAA. Outcomes: Primary outcome is the functional outcome at one year after pelvic pouch surgery. This will be measured using the validated Colorectal Functional Outcome (COREFO) questionnaire. Secondary outcomes are functional outcome at 3 and 6 months, male and female sexual function, perioperative measures and clinical measures. Sample Size: A sample of 48 (24 per group) is required to detect a between-group non-inferiority margin of 7.05 in COREFO score with a 1-sided α of 0.05 and a power of 80%, allowing for 20% attrition. A participation rate of 50% is anticipated. Analysis: All continuous variable outcomes will be compared using analysis of covariance. Categorical variable outcomes will be analyzed using repeated measures logistic regression. Proportional outcomes will be analyzed with the chi-square or Fisher's exact test and continuous variables will be analyzed with student's t-test. Follow-up: Each participant will be followed up at 6 weeks, 3 months, 6 months and 12 months after the intervention to assess functional scores and clinical events. Perioperative events (including postoperative complications) will be assessed during the intervention hospitalization period.
