Active clinical trials for "Colitis, Ulcerative"

The treatment for Ulcerative Colitis (UC) aims to achieve and maintain remission and is usually lifelong and expensive. Current available medications are unable to break the cycle of chronic inflammation, and still a significant proportion of patients will fail to respond (primary non-response) or lose response over time (secondary non-response). There is now growing evidence that there is substantial interpatient variation in the composition of the inflammation associated network of immune cells. A deeper knowledge of the patient's alterations in the mucosal immune response would help identify key drivers of inflammation and select the appropriate therapy. By analyzing the changes in the composition of immune cells induced by Janus Kinase (JAK) inhibition, we aim to obtain a better insight into the mechanistic effects of JAK inhibition and the downstream effects. These mechanistic insights are needed to identifying potential responders and non-responders in the future.

The primary objective is to assess if discontinuation of anti- tumor necrosis factor alpha (TNF) treatment in ulcerative colitis patients in sustained clinical remission, with the option to restart treatment in the case of relapse, is non-inferior to continued anti-TNF treatment. Secondary objectives are to assess the efficacy and safety of restarting anti-TNF treatment after a relapse

The purpose of this study is to determine the safety profile of long-term vedolizumab IV treatment in pediatric participants with UC or CD.

The purpose of this study is to evaluate efficacy of golimumab in inducing clinical remission as assessed by the Mayo score, in pediatric participants with moderately to severely active ulcerative colitis (UC). In addition, the safety profile of golimumab, in pediatric participants with moderately to severely active UC will be assessed.

The purpose of this study is to evaluate safety and efficacy of risankizumab in participants with ulcerative colitis (UC) in participants who responded to induction treatment with risankizumab in a prior AbbVie study of risankizumab in UC. This study consists of three sub-studies and a Continuous Treatment Extension (CTE): Substudy 1 is a 52-week, randomized, double-blind, placebo-controlled maintenance study; Substudy 2 is 52-week, randomized, exploratory maintenance study; and Substudy 3 is an open-label long-term extension study for participants who completed Substudy 1 or 2, or participants who responded to induction treatment in Study M16-067 with no final endoscopy due to the Covid-19 pandemic or due to the geopolitical conflict in Ukraine and surrounding impacted regions. The CTE is an open-label extension for Substudy 3 completers to ensure continuous treatment with risankizumab until such time that risankizumab becomes commercially available and/or the subject can access treatment locally or can transition to a Continued Treatment for Trial Participants Open-Label Extension study.

A double-blind, randomized, placebo-controlled clinical trial examining the efficacy and safety of Fecal Microbiota Transplantation (FMT) and high fiber supplementation in patients with active mild to moderate Ulcerative Colitis (UC). All enrolled subjects will provide serological, stool and mucosal specimen at each clinic visit to help further define the alterations in microbial profiles and immune cell function in response to psyllium fiber after FMT treatment.

A phase 2b study to evaluate the long-term efficacy and safety study of ABX464 50mg as maintenance therapy in patients with moderate to severe Ulcerative Colitis.

The purpose of this study is to assess the safety and efficacy of PRA023 in participants with moderately to severely active Ulcerative Colitis. The purpose of Cohort 2 of the study is to assess the safety and efficacy of PRA023 in participants with moderately to severely active ulcerative colitis who are companion diagnostic positive. After the completion of the 12-week induction, all participants have the option to continue in the open-label extension for another 38 weeks.

This is a study to understand if taking VTX002 daily as a tablet orally is safe and effective in participants diagnosed with moderate to severe ulcerative colitis (UC). Approximately 189 participants will take VTX002 Dose A, VTX002 Dose B, or matching placebo, once daily. The study consists of a 28-day Screening Period (to see if a participant qualifies for the study), a 13-week double-blind period (a participant receives either active Dose A, Dose B or Placebo), a Long-Term Extension (LTE) Treatment Period of up to 39 weeks, an Open-Label Extension (OLE) Treatment Period of up to 143 weeks, and a 2-week Follow-Up Period. The maximal duration of treatment including the Induction Period, LTE and OLE will be 36 months.

This study is designed to evaluate the long-term safety and efficacy of Upadacitinib in participants with ulcerative colitis (UC) who have not responded at the end of the induction period in Study M14-234 Substudy 1, who have had loss of response during the maintenance period of Study M14-234 Substudy 3, or who have successfully completed Study M14-234 Substudy 3.
