Active clinical trials for "Colitis"

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.

The purpose of this study is to investigate whether a novel dosage form of a prednisolone ester, called COLAL-PRED®, is useful in the treatment of ulcerative colitis.

The purpose of this study is to assess the safety and efficacy of golimumab administered subcutaneously (under the skin) injections in maintenance therapy.

The purpose of this clinical research study is to learn if abatacept can improve signs and symptoms of active ulcerative colitis in patients who have not had an adequate response to other therapies. The safety of this treatment will also be studied

The purpose of this study is to evaluate the effectiveness and safety of infliximab (Remicade) in patients with Ulcerative Colitis.

To determine the oral bioavailability of three dose levels of oral ganciclovir given with and without glutamic acid hydrochloride in patients with cytomegalovirus (CMV) GI disease, and to compare the bioavailability of these regimens to that of standard intravenous (IV) ganciclovir. Long-term ganciclovir maintenance therapy has been recommended for CMV colitis or esophagitis following induction treatment. Oral ganciclovir is a likely candidate for maintenance because of its possible therapeutic value and ease of administration, but an optimum dose has not been determined. Since oral ganciclovir has a low bioavailability and is more soluble in an acid pH environment, the addition of glutamic acid hydrochloride may enhance gastrointestinal absorption of this drug.

Immune checkpoint inhibitors (ICI) might induce inflammatory potentially serious and even lethal immune related Adverse Events (irAEs). Diarrhea and/or colitis are ones of the most frequently reported irAEs in patients taking ICI. Although the immune mechanisms underlying irAEs have not been fully elucidated, studies suggest that Th17 and Tregs cells, increases in expression of immunologically-related genes, eosinophilia, microbiome among others and cytokines may be involved in the pathophysiology of immune-related complications in some diseases that resemble irAEs, such as colitis and rheumatic manifestations. Importantly, interleukin-6 (IL-6) promotes the differentiation of naïve CD4+ T cells into Th17 cells (17), and IL-6 inhibition may rebalance the altered Th17-Treg axis without inhibiting the Th1-CD8+ T-cell subsets that govern antitumor immunity. These findings raise the possibility of using IL-6 blockade as a strategy for treating colitis and arthritis induced by immune checkpoint blockade.

Phase IIb study to evaluate the efficacy and the safety of 3 dose-levels of ABX464, administered daily in patients with moderate to severe Ulcerative Colitis.

This is a Phase IIa (proof of concept), randomized, double blind, placebo-controlled, multicentre clinical trial to evaluate the safety and efficacy of daily PBF-677 oral treatment during 28 days in Ulcerative colitis (UC) patients who are not receiving immunosuppressants and present mild-to-moderate activity of the disease. Enrolled patients would receive standard high doses of 5-ASA (4g), according to current clinical guidelines, and are randomized to receive also PBF-677 or placebo.
