NCT ID: NCT05938465 Recruiting - Ileal Pouch Clinical Trials

Study of EXE-346 Live Biotherapeutic to Reduce High Bowel Movement Frequency in Subjects With an IPAA (PROF)

PROF
Start date: October 11, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

The aim of this study is to assess the safety and preliminary efficacy of treatment with EXE-346, a live biotherapeutic, which may reduce bowel movement frequency in patients with an ileal pouch-anal anastomosis (IPAA) and lead to a higher quality of life.

NCT ID: NCT04722757 Recruiting - Ulcerative Colitis Clinical Trials

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.

NCT ID: NCT04695964 Recruiting - Colorectal Cancer Clinical Trials

Objective Perfusion Rate Assessment by Near-infrared Fluorescence in Ileal Pouch Formation and Ileal-pouch-anal Anastomosis

Start date: February 1, 2019
Phase: N/A
Study type: Interventional

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. Postoperatively, a detailed software-based assessment of each pouch recording is performed to determine the objective ICG-NIRF perfusion rate, which is then correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.

NCT ID: NCT04695184 Recruiting - Colorectal Cancer Clinical Trials

Subjective Near-infrared Fluorescence Guidance in Perfusion Assessment of Ileal Pouch Formation and Ileal-pouch-anal Anastomosis

Start date: February 1, 2019
Phase: N/A
Study type: Interventional

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. The intraoperative imaging findings are then analysed and correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.

NCT ID: NCT04519684 Recruiting - Crohn Disease Clinical Trials

Study of Mesenchymal Stem Cells for the Treatment of Ileal Pouch Fistula's in Participants With Crohn's Disease

IPAAF
Start date: October 28, 2020
Phase: Phase 1/Phase 2
Study type: Interventional

Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) is the procedure of choice for patients with ulcerative colitis, familial adenomatous polyposis, and select patients with Crohn's disease due to overall low patient morbidity and good quality of life. However, some patients can develop Crohn's disease of the pouch, a clinical diagnosis of Crohn's disease following IPAA. One of the manifestations of Crohn's disease of the pouch includes a fistula from the pouch that travels to the vagina or perianal area. These fistulas can be quite difficult to manage with medications and local surgical intervention, and, on occasion result in a reconstruction pouch but more often require a pouch excision with permanent end ileostomy. The purpose of this study is to evaluate the safety and efficacy of using allogeneic bone marrow derived mesenchymal stem cells to treat people who have a peri-pouch fistula related to a clinical diagnosis of Crohn's disease of the pouch.

NCT ID: NCT03536988 Recruiting - Ulcerative Colitis Clinical Trials

NCT ID: NCT03136419 Recruiting - Ulcerative Colitis Clinical Trials

Microbiota and Immune microEnvironment in Pouchitis

MEP1
Start date: October 31, 2016
Phase: N/A
Study type: Interventional

Microbiota and innate immunity in pouchitis: predisposing factors and modulation of the inflammation with probiotics. Around 20-25% of ulcerative colitis patients undergo restorative proctocolectomy with ileal pouch anal anastomosis. Pouchitis is an idiopathic inflammatory disease that may occur in ileal pouches. In our recent studies, we showed altered microbiota and innate immunity relationships in pouchitis. We plain to perform a double-blind, placebo-controlled trial probiotic therapy vs placebo starting at the time of ileostomy closure to evaluate the impact of microbiota that colonizes the pouch mucosa in the pathogenesis of pouchits, to determine how expression and activation status of the innate immunity system in different cell types and anatomical districts of pouch mucosa relate to microbiota population and follow-up the clinical outcome of anal pouches in light of microbiota-innate immune system interplay. Our study will include three phases: 1. analysis of the intestinal microbiota with High Throughput Sequencing Unit and anaerobes cultures 2. characterization of innate immunity with TLR, NLR, nicotinic receptors and LPMC analysis 3. assessment of microbiota and innate immune system in the ileal pouch before ileostomy closure, 2 months after ileostomy closure and after 1 year follow up.
