Filter by:The aims of our study are to evaluate the feasibility and safety of endoscopic injection of adipose tissue-derived mesenchymal stem cells in human subjects with moderate active ulcerative colitis, assessing the absence of adverse events associated to the investigational drug, and to evaluate the efficacy of the treatment to induce remission of moderate active ulcerative colitis, by improvements in disease activity index, quality of life index, and endoscopic index.
The purpose of this research study was to compare the medication TP05 to the medication Asacol™ for the treatment of ulcerative colitis (UC) and to assess the safety and tolerability of TP05. This study investigated whether TP05 is as good as (non-inferior to) Asacol™(1). (1)The trademark Asacol™ is registered in over 55 countries as Asacol™ and as Octasa™, Fivasa™, Lixacol™, Asacolon™ in the United Kingdom, France, Spain and Ireland, respectively. The rights to Asacol, including the rights to the trademark, are owned by Tillotts Pharma AG in various countries except for the following: Switzerland, USA, United Kingdom, Canada, Italy, Belgium, the Netherlands and Luxembourg.
The purpose of this study is to evaluate the pharmacokinetics (what the body does to the study medication) and safety of subcutaneously (under the skin) administered golimumab in pediatric participants (aged 2 to 17 years) with moderately to severely active Ulcerative Colitis (UC).
The purpose of this study is to determine whether fecal microbiota transplantation (FMT) is safe and efficacious in the treatment of chronic active ulcerative colitis (UC) by conducting a randomised controlled trial
The purpose of the study is to develop a validated French version of the IBDQ in a cohort of patients suffering from Inflammatory bowel diseases, namely Crohn's disease and Ulcerative Colitis.
A study with an 8 week open label phase study followed by a year long placebo controlled maintenance phase in subjects with active mild to moderate ulcerative colitis (UC), with a modified Mayo Score 4-10 and an endoscopy subscore of 2-3, taking mesalamine (or equivalent) as a concomitant medication. Subjects are required to be in clinical remission or clinical response to enter the year long maintenance phase. This study will help evaluate if HMPL-004 is effective in subjects maintaining clinical remission following successful induction therapy achieving clinical remission or clinical response.
Assess if standardized care-path that features objective evaluations of disease activity and time-bound algorithms is superior to usual step-care in the treatment of ulcerative colitis.
The risk for colon cancer in patients with longstanding ulcerative colitis exceeding the rectum is increased and therefore patients should be enrolled in a surveillance program eight years after the diagnosis. Until today, official international guidelines for endoscopic screening in patients with ulcerative colitis advise to take 4 biopsies every 10 centimeters (with a minimum of 32) and of each suspected visible lesion. These guidelines are merely based on consensus during expert opinion meetings rather than evidence based. Recent studies have shown that chromo-endoscopy guided biopsies significantly reduced the number of biopsies for each procedure and detected more neoplastic lesions. Chromo-endoscopy is therefore considered the gold standard in this study in which we want to compare it to the performance and efficiency of new endoscopic imaging techniques. Narrow-Band Imaging (NBI) selectively uses certain wavelengths of the visible light leading to a shift in the excitation spectrum towards blue light. The first studies with NBI showed that the additional value of NBI in the detection of neoplastic lesions is comparable to chromo-endoscopy, but time saving and easier to perform. The Fujinon Intelligent Chromo-Endoscopy (FICE) system uses a similar theoretical principal as NBI but this is achieved via the use of post hoc computer algorithms, applying different filters to the stored endoscopic images and enabling a theoretically endless number of combinations of filters that can be used. The Pentax I-scan system also allows post hoc modification of the images. On the one hand, surface enhancement enables to better highlight mucosal changes. Spectral modification allows to apply different modes in analogy with to FICE system. These new imaging techniques have a theoretical advantage which is extendedly used for sales purposes but has however so far not been proven in ulcerative colitis patients. We want to test their clinical use in the screening for neoplastic lesions in patients with long standing ulcerative colitis.
The study is on indefinite HOLD due to the loss of funding that occurred during the pandemic emergency. Subsequently, a key collaborator left our institution, and as a near-term result, the protocol awaits reactivation. Three patient subjects were enrolled, all 3 patients/subjects were cured of the infection, and there were no adverse events or sequelae observed or reported. The aim of the study continues to confirm and extend the work of Trede and Rask-Madsen (Lancet 1989;1:1156-1160) that administration of a defined fecal microbiota will lead to rapid and sustained resolution of C. difficile-associated chronic relapsing diarrhea. FDA required 4 non-geriatric qualified patients to be studied before including the elderly. However, C. difficile-associated chronic relapsing diarrheal illness is predominantly a disease of the elderly, so this requirement GREATLY impeded timely enrollment. No protocol deviations have occurred. The current rationale behind FMT for CDI is that the introduction of microbes from a healthy donor should allow for the restoration of a normal microbial community in the diseased host with consequent suppression of C. difficile colonization and disease pathogenesis. The first modern use of FMT was reported in a 1958 case series of 4 patients with pseudomembranous enterocolitis. The first case of confirmed CDI treated with FMT was reported in 1983; treatment was curative. Until 1989, retention enemas were the most common technique for FMT. Alternative methods for delivering FMT have included fecal infusion via duodenal tube (1991), rectal tube (1994), and colonoscopy (1998). FMT for recurrent CDI has been used successfully, whether administered by nasogastric tube, rectal administration by colonoscopy, or rectal tube, including self-administration at home by enema. FMT has proven to be remarkably effective and remarkably safe without any significant problems (see below and attached reviews and meta-analyses). Increasing interest is emerging regarding the changes in the intestinal microbiota associated with CDI. In 2008 Chang et al. constructed small (< 200 sequences per subject) 16S rRNA gene libraries from the stools of 4 patients with first-time CDI and 3 patients with recurrent CDI. Based on 16S rRNA gene classification, they found that the fecal microbiomes of patients with an initial episode of CDI were similar at the phylum level to healthy subjects (i.e., the majority of sequences belonged to dominant fecal phyla Bacteroidetes and Firmicutes), while a major reduction or loss of Bacteroidetes was observed in patients with recurrent CDI. The loss of the Bacteroidetes was accompanied by the expansion of other phyla, including Proteobacteria and Verrucomicrobia, which are normally minor constituents of the fecal microbiota. Khoruts et al. (2010) compared the microbiota of a patient with recurrent CDI before and after FMT by using terminal-restriction fragment length polymorphism and clone-based 16S rRNA gene sequencing. Before transplantation, the patient's microbiota was deficient in members of Bacteroides and instead was composed of atypical fecal genera such as Veillonella, Clostridium, Lactobacillus, Streptococcus, and unclassified bacteria similar to Erysipelothrix. Two weeks after the infusion of donor fecal suspension, the bacterial composition of her feces approached normal and was dominated by Bacteroides sp. strains. In 1989, Tvede and Rask-Madsen used a combination of nine normal fecal organisms to treat 6 patients with chronic relapsing C. difficile diarrhea. These investigators cultivated 10 strains of bacteria, including Enterococcus (Streptococcus) faecalis (1108-2), Clostridium inoculum (A27-24), Clostridium ramosum (A3I-3), Bacteroides ovatus (A40-4), Bacteroides vulgatus (A33-14), Bacteroides thetaiotaomicron (A33-12), Escherichia coli (1109), E. coli (1108-1), Clostridium bifermentans (A27-6), and Blautia producta (Peptostreptococcus productus) (1108-2) in broth for 48 h to a concentration of approximately 10 to the 9th power bacteria/mL. Two mL from each bacterial culture were admixed with 180 mL saline that had been pretreated in an anaerobic chamber for 24 h; the bacterial suspension was then instilled rectally. This procedure was followed promptly by a decline of C. difficile to undetectable levels by culture and the loss of detectable toxin from the stools. Normal bowel function was restored within 24 hours, and abdominal symptoms disappeared. Stool cultures and toxin assays for C. difficile remained negative during a year of follow-up. It is especially important to note that feces from none of the 6 patients contained Bacteroides sp.
