Active clinical trials for "Colitis, Ulcerative"

The purpose of this study is to determine whether a treatment of a novel leukapheresis column is safe and effective in patients with moderate to severe ulcerative colitis.

This is a single center, open label forced dose titration study designed to determine the tolerability of curcumin in pediatric patients with inflammatory bowel disease (IBD). This study will provide initial tolerability and safety data in pediatric patients with IBD. Twenty patients with IBD in remission or with mild disease (score <34 on PUCAI or score <30 on the PCDAI) on sulfasalazine or mesalamine aged 8 to 18 years will be enrolled into this study. Each patient will participate in the study for nine weeks. From this study an appropriate dosage will be determined to proceed with a double blinded placebo controlled study.

The objective of this study is to evaluate the efficacy and the tolerability of oral parnaparin sodium (210mg), administered in extended-release tablets identified as CB-01-05-MMX™.

The purpose of this study is to evaluate the safety and efficacy of HMPL-004 in patients with active mild to moderate ulcerative colitis (UC), compared with placebo.

The purpose of the study is to demonstrate the safety and effectiveness of the Adacolumn Apheresis System to treat the signs and symptoms of ulcerative colitis.

The purpose of this study is to examine the safety and efficacy of rebamipide by once daily intracolonial administration at 0 (placebo), 60, 150, or 300 mg for 6 weeks in patients with active ulcerative colitis, who are being treated with oral aminosalicylic acid (ASA).

This dose comparison study, taking place at over 200 sites worldwide, will compare the dosing, safety and efficacy of an investigational medicine OPC-6535 to the dosing, safety and efficacy of Asacol ® in the maintenance of remission in subjects with ulcerative colitis.

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.

There is broad support for the hypothesis that Ulcerative colitis is an auto-immune disease. Rituximab is an antibody protein that removes a subgroup of white blood cells (B lymphocytes) from the circulation. These cells have the capacity to generate the auto-antibodies that typify auto-immune disease. Although Rituximab has been mainly used for treating B lymphocyte malignancies (lymphoma) it has also been used with promising results in Rheumatoid arthritis and has an excellent safety record. This is a small placebo-controlled trial to assess its efficacy and safety in patients with steroid-resistant active ulcerative colitis.

The purpose of this study is to evaluate if retarded release phosphatidylcholine is an effective alternative to steroid dependent or -refractory course in chronic active ulcerative colitis. The hypothesis is, that ulcerative colitis is caused by a barrier defect of the colonic mucus layer. The background of the study is the finding, that the phosophatidylcholine content of the colonic mucus is strongly reduced in ulcerative colitis (UC) compared to healthy controls and patients with Crohn´s disease. The content was measured in non-inflamed areas of the colon in UC. Thus, we evaluate whether a substitution of colonic PC is an effective method for steroid dependent UC.
