Active clinical trials for "Colitis, Ulcerative"

Ulcerative colitis is a condition that mainly affects young adults where the lining of the bowel is inflamed causing bloody diarrhea. The cause of ulcerative colitis is unknown and treatments remain imperfect with no cure for the disease. Initial success has been shown with a highly novel treatment where patients with active ulcerative colitis receive a fecal enema to try and replace their stool containing bacteria that may be driving their disease with that from a healthy donor. To assess if this works by comparing how well it treats the disease compared to a placebo enema.

The purpose of this study is to evaluate the the efficacy of TA-650 using Clinical activity index (CAI) score and other evaluation indicators in pediatric patients with moderate to severe ulcerative colitis after TA-650 administration of at a dose of 5 mg/kg at weeks 0, 2, and 6, and then every 8 weeks at weeks 14 and 22. The safety and pharmacokinetics are also evaluated.

Ulcerative Colitis (UC) is a life-long incurable disease with remissions and exacerbations. Inflammation confined to the rectum occurs in a quarter of patients and can be extremely hard to treat. Many medications have been tried in order to control the inflammation, but they do not always work. One of the newer medications is the immunosuppressing medication, tacrolimus that has been shown to be effective in UC when taken orally. Unfortunately, the oral use of this medication can have numerous serious side effects. In order to overcome these side effects, the use of topical rectal tacrolimus has been examined. Pilot studies in ulcerative proctitis (inflammation confined to the rectum) resistant to conventional therapies have demonstrated a clinical remission in 75% of patients and although the medication was well absorbed through the lining of the bowel, the levels in the blood were very low and no serious side effects were reported. The findings suggest that this preparation is indeed effective for inflammation in the distal bowel and that the method of administration reduces side effects. Further work, however, now needs to be undertaken to validate the original findings.

The purpose of this research study is to: 1) Test the safety and tolerability of 2 different oral doses of SRT2104 in subjects with ulcerative colitis 2) Determine the amount of SRT2104 measured from a single blood sample in addition to colon and/or rectal tissue samples (biopsies) 3) Determine whether SRT2104 has any anti-inflammatory effect on the colon and/or rectum when taken orally for 8 weeks 4) Determine whether SRT2104 causes any detectable changes to specific biomarkers. A biomarker is a biological marker (or substance such as a protein) that is used as an indicator of changes in a biological state that corresponds to the risk or progression of a disease.

The objective of the proposed study is to determine whether BL-7040 demonstrates clinical efficacy in patients with inflammatory bowel disease (IBD).

Open-label, 8 week study, to assess the efficacy and safety of oral Budesonide-MMX 9 mg Extended-release Tablets in patients with mild to moderate, active ulcerative colitis who are not in remission based on the Ulcerative Colitis Disease Activity Index in study CB-01-02/01 (parent study [NCT00679432]).

This is a first-in-man study of a novel investigational botanical drug complex, PUR 0110 rectal enema, that has been shown to have potent anti-inflammatory, antioxidant and immunomodulatory effects following in vitro and in vivo pharmacology studies, to assess the safety and tolerability of sequential single-ascending doses in normal healthy volunteers and to determine the maximum tolerated dose (MTD). As a tertiary objective, the study will also investigate the presence of specific pharmacokinetic markers following the administration of single-dose PUR 0110 at each dose level. The study is designed as a single-center, randomized, double-blind, parallel-group, sequential single-ascending dose, placebo-controlled safety, tolerability and pharmacokinetic study of PUR 0110 rectal enema in 24 normal healthy male volunteers. Eligible subjects will be randomly assigned to 4 Cohorts of 6 subjects each to receive active drug (PUR 0110 Enema) or placebo enema as follows: 187.5 mg/60 g - Cohort 1, 375 mg/60 g - Cohort 2, 750 mg/60 g - Cohort 3 or 1500 mg/60 g - Cohort 4. Within each Cohort, subjects will be randomized in a 2:1 ratio to receive either active treatment (PUR 0110 enema; n = 4) or placebo enema (n = 2). Each subject will receive only 1 dose of assigned study medication and dosing of subjects within each cohort will also be by sequential inclusion.

The purpose of the study is to obtain a first clinical assessment of the safety of dersalazine sodium in ulcerative colitis patients with mild to moderate disease.

Anal sphincter preserving operations are now commonplace for both cancer and non-cancerous rectal diseases. However, this has not always been the case and this development has been facilitated by the invention of circular stapling instruments, which allow the bowel to be reconnected to the anal sphincters, where it would almost be impossible to do so manually. Nevertheless, some patients still require a permanent ostomy, as even with stapling devices ultra low joins of the bowel and sphincter muscles cannot always be performed by a conventional surgery. Therefore, a variety of alternative techniques have been proposed to avoid a permanent ostomy, but these have not become widespread due to the technical difficulty in performing them, their failure to completely eradicate rectal disease, and the damage they inflict upon the anal sphincters resulting in poor bowel function after surgery. The ideal ultra low sphincter preserving operation should remove the rectal disease entirely, allow the small or large bowel to be safely joined to the anal sphincters under direct vision, and retain the sphincter mechanism in its entirety. We propose such a technique that we term the APPEAR procedure, which approaches the lower third of the rectum via an incision between the scrotum or vagina, and the anal sphincters. This procedure preserves sphincter integrity, and allows either a stapled or manual join of the bowel to the sphincter mechanism, under direct vision. This trial is being conducted as a pilot study, with the procedure only offered to patients for whom a conventional sphincter saving procedure was technically impossible, or contraindicated.
