The total participation duration includes treatment and long-term observation to evaluate outcomes and any potential changes in liver health.

Researchers are evaluating the effects of two oral drugs, ECC4703 and ECC0509, alone and in combination, on reducing liver fat in adults with presumed Metabolic Dysfunction-associated Steatohepatitis MASH. This phase 2a trial compares low and high doses of each drug and their combination with a placebo to assess changes in liver fat using MRI at 12 weeks. Participants are randomly assigned to one of several groups receiving either placebo, low or high doses of ECC4703, low or high doses of ECC0509, or a combination of high doses of both drugs. Each treatment is given as oral capsules. The main study period lasts 12 weeks during which participants take the assigned capsules and undergo evaluations. During the trial, participants will have multiple assessments including MRI scans to measure liver fat, blood tests to monitor liver enzymes and metabolic markers, and quality of life questionnaires. Drug levels in the blood will be measured at several time points. The study measures liver fat reduction primarily at 12 weeks and monitors safety and various biochemical markers throughout the period.

Researchers are evaluating the use of Vedolizumab in adults with moderate to severely active Ulcerative Colitis UC or Crohns Disease CD, which are chronic gut conditions causing symptoms such as diarrhea, inflammation, bleeding, and abdominal pain. The study aims to measure how many participants achieve remission, meaning their symptoms disappear, after 14 weeks of treatment. This is a Phase 4 treatment study sponsored by Takeda, focusing on the effectiveness of Vedolizumab administered in a community setting. Participants with either UC or CD will receive Vedolizumab intravenously IV during the first 6 weeks, with doses given at Weeks 0 and 2, and possibly an additional IV dose at Week 6. After this initial period, participants may switch to subcutaneous under the skin injections of Vedolizumab every two weeks from Week 6 until Week 50. If the treatment does not appear effective by Week 14, participants may stop Vedolizumab and switch to another therapy. Additional required visits occur at 26 weeks and 52 weeks, with a final check 18 weeks after the last Vedolizumab dose. Throughout the study, participants will visit the clinic multiple times for treatment and monitoring. Assessments include patient-reported symptom measures at Weeks 6, 14, and 52, clinical response evaluations, and endoscopic examinations to observe mucosal healing. Blood and stool tests will measure inflammation markers like C-reactive protein and fecal calprotectin. Safety monitoring will track serious infections up to 72 weeks. Overall, participants are involved for about one year of treatment plus follow-up to evaluate the long-term effects of Vedolizumab.

This research aims to evaluate the effects of vedolizumab intravenous IV combined with either adalimumab or ustekinumab in adults with moderate to severe Crohns Disease who have not responded adequately or have lost response to certain prior treatments. The study investigates the safety and efficacy of these dual targeted therapies, followed by vedolizumab alone. Approximately 100 participants will be enrolled, with the overall study duration lasting about 76 weeks. Participants in Part A will receive dual targeted therapy one group will get vedolizumab IV plus adalimumab subcutaneous injections, and another group will receive vedolizumab IV combined with ustekinumab through initial IV infusion followed by subcutaneous doses. Those who respond to Part A treatment will continue in Part B, receiving vedolizumab IV monotherapy every 8 weeks from Week 30 to Week 46. After treatment, participants will have a safety follow-up period extending to Week 72. During the study, participants will undergo multiple assessments including endoscopic evaluations using the Simple Endoscopic Score for Crohns Disease SES-CD at Weeks 26 and 52. Clinical remission and symptom remission will be tracked at various time points using the Crohns Disease Activity Index CDAI and patient-reported outcome measures. Safety monitoring and follow-up continue for at least 26 weeks after the last treatment dose to evaluate treatment effects and adverse events throughout the study period.
