Filter by:Colectomy with creation of an ileal pouch (IPAA) is now the treatment of choice for patients with ulcerative colitis that is resistant to existing medical therapies. The development of inflammation in these ileal reservoirs, a clinical entity referred to as pouchitis, is the most common long-term complication of this procedure and can affect 50-60% of adults and children. We have previously demonstrated that clotrimazole (delivered as a rectal suppository) is generally safe, effective, and displays poor systemic absorption when used in pediatric and adults with active pouchitis. We saw clinical benefit in patients with pouch disease that had previously failed to respond to standard antibiotic, steroid, or immunosuppressive therapies. The clinical trial outlined here will define the effectiveness and safety of topical clotrimazole therapy (delivered as a rectal enema) in pediatric (aged greater than two years) and adult patients with pouchitis. Subjects in this study will be randomly assigned to receive either placebo (no active drug, 4 subjects) or one of two clotrimazole therapy groups: 2500 mg/day (8 subjects) or 4000mg/day (8 subjects). No washout period is required, and subjects will be allowed to continue their existing anti-inflammatory medications during their participation in the study. Clotrimazole will be delivered nightly in the form of an enema. Subjects will undergo flexible sigmoidoscopy (pouchoscopy) prior to and again after completing one month of study therapy, and pouch disease activity will be graded at after each procedure using the Pouchitis Disease Activity Index (PDAI). Clinical improvement will be defined as a drop in PDAI score. If the drop in PDAI scores between placebo and either active clotrimazole treatment group is not significant, and no subject experiences what are determined to be study-related adverse effects, a second cohort of subjects will be recruited and studied after receiving one month of either placebo (4 subjects), 6000 mg/day clotrimazole (8 subjects), or 7500mg/day clotrimazole (8 subjects). Subjects will be assessed for adverse effects at the midpoint of the study. Clotrimazole blood levels will be measured during the first and last day of study participation. In addition, adults will complete a health related quality of life assessment at baseline and after completing study drug therapy. All subjects will be eligible for one month of open-label study drug therapy after completing one month of study drug therapy.
This study will evaluate the safety and effectiveness of the drug interferon-beta1a (AVONEX) in treating ulcerative colitis and examine the drug's effect on the immune system. People with ulcerative colitis have increased amounts of inflammatory chemicals (cytokines) made by immune cells in the lining of the colon. Studies have shown that interferon-beta may block the activity of these cytokines. Interferon-beta1a (AVONEX) is currently FDA-approved to treat multiple sclerosis, a disease involving inflammation of the brain and spinal cord. Patients 18 years of age and older who have had ulcerative colitis for at least 4 months may be eligible for this study. Candidates will be screened with a review of their medical records, a medical history and physical examination, electrocardiogram (EKG), blood, urine, and stool tests, and a pregnancy test for women of childbearing potential. A colonoscopy will also be done to determine disease activity and extent. This test uses a lighted tube to examine the amount of inflammation in the colon and take tissue samples (biopsies) for testing. Before the test, the patient is given a medicine to allay anxiety and the discomfort of inserting the endoscope into the rectum. This flexible tube allows the doctor to see the intestinal mucosa and project an image of the inner lining of the intestine onto a TV monitor. At various places in the intestine, small pieces of tissue are plucked out by a special device at the tip of the endoscope. The procedure generally lasts 30 minutes to 1 hour. Participants will come to the NIH Clinical Center once a week for 4 weeks to receive an injection of interferon-beta, fill out questionnaires, and have a symptoms check, physical examination, and blood tests. Patients whose colitis has not worsened at the end of the 4 weeks and who have not had significant drug side effects will continue to receive weekly injections for an additional 8 weeks. Some patients may receive some of the last eight injections outside of NIH, but all patients will visit the Clinical Center visits every 3 to 4 weeks for a physical exam, symptoms check and blood tests. After the 12 injections are completed, patients will have another colonoscopy to evaluate the response to treatment and will return to the Clinical Center every 6 weeks for a total of four visits, for a physical examination, symptoms check and blood tests.
To explore the safety of orally delivered rhIL-11 in patients with mild to moderate left-sided ulcerative colitis. To explore the effects of orally administered rhIL-11 on pharmacogenomics in blood samples and in colonic biopsy tissue samples.
The purpose of this study is to evaluate the effectiveness and safety of infliximab (Remicade) in patients with Ulcerative Colitis.
This study will evaluate the effectiveness and safety of the experimental compound OP2000 (deligoparin) in patients with active ulcerative colitis. Patients eligible for this study will have received (and will continue to receive) stable doses of aminosalicylates (oral, enema and/or suppository), if tolerated. OP2000 is an ultra low molecular weight heparin with anticoagulant (blood thinning) and anti-inflammatory actions that may be of benefit for the treatment of ulcerative colitis.
The purpose of the study is to evaluate an intravenous (by injection) investigational medication to treat severe ulcerative colitis refractory to steroid therapy. The research is being conducted at up to 8 clinical research sites in the US and is open to both men and women ages 18 to 70 years old. Participants in the study will have a number of visits to a research site. All study-related care and medication is provided to qualified participants at no cost: this includes all visits, examinations and laboratory work.
OBJECTIVES: I. Assess the safety and efficacy of 4-aminosalicylic acid in patients with mildly to moderately severe ulcerative colitis.
This study will investigate in patients with Crohn s disease and ulcerative colitis how the body s immune system controls inflammation in the gastrointestinal tract (stomach and intestines)-specifically, how lymphocytes (a type of white blood cell) function in inflammatory responses. This protocol does not involve any experimental treatments. Patients between the ages of 0 and 75 years of age with Crohn s disease or ulcerative colitis or symptoms of inflammatory bowel disease may be eligible for this study. Screening tests may include the following: medical history and physical examination, routine blood tests, examination of stool specimens, X-rays such as barium enema or upper GI series, proctosigmoidoscopy, colonoscopy, gastroduodenoscopy, and small bowel biopsy. Participants will receive medical treatment according to the best generally accepted measures for treating Crohn s disease or ulcerative colitis. This may include anti-inflammatory drugs, immunosuppressive drugs, and antibiotics to treat infections. A surgical consultation may be recommended for patients whose disease does not respond to medical treatment. If surgery to remove intestinal tissue is recommended, a qualified gastrointestinal surgeon will perform the procedure. In addition, participants may undergo the following procedures: - Blood drawing - No more than 450 milliliters (30 tablespoons, or 15 ounces) of blood will be taken from adults over a 6-week period. A maximum of 7 ml (1/2 tablespoon) of blood per kilogram (2.2. pounds) of body weight will be obtained from children within the same time period, with no more than 3 ml/kg taken at any one time. - Leukapheresis - This procedure is done to collect large quantities of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood is circulated through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm. - Intestinal biopsies - Intestinal tissue will be obtained during colonoscopy with intestinal biopsy in patients who require this procedure as part of their standard medical care. Patients are given a sedative to reduce anxiety, but are conscious during the procedure. A flexible tube is inserted into the rectum and large intestine, allowing the physician to see the intestinal mucosa. At various places, small pieces of tissue are plucked out.
