Safety, Dosage, and Microbiome Engraftment Study of MGT-006 for Ulcerative Colitis (ROOT Study)

Ulcerative colitis is a condition that causes inflammation and ulcers in the large intestine. MGT-006 is an investigational oral capsule containing viable gut microbiota from screened human donors. This study will evaluate the safety and tolerability of MGT-006 in adults with moderately active ulcerative colitis. It will also examine whether gut microbiota from MGT-006 engraft in participants' intestines and explore changes in ulcerative colitis symptoms and inflammation. The study has two parts. In Phase 1b, participants will be randomly assigned to receive MGT-006 either without antibiotic pretreatment or after five days of oral vancomycin or AFM (Amoxicillin/Fosfomycin/Metronidazole) pretreatment. MGT-006 will be taken for eight weeks, followed by four weeks of observation. Phase 2a is planned to explore different doses and potentially different dosing regimens of MGT-006, using the pretreatment approach selected from Phase 1b. The final Phase 2a design will depend on the Phase 1b findings and will be specified in an amended protocol before Phase 2a begins.

LY4268989 in Adults With Moderately to Severely Active Ulcerative Colitis

The main purpose of this study is to evaluate the safety and effectiveness of LY4268989 when compared to placebo in adult participants with moderately to severely active ulcerative colitis (UC). The study drug will be administered orally. The study will last up to approximately 108 weeks, excluding screening.

Tacrolimus Lipid Suspension for Enema in Adult Subjects with Mild to Moderately Active Left-sided/Distal Ulcerative Colitis Who Had an Inadequate Response to the Treatment

The study will evaluate the effectiveness, safety and tolerability of tacrolimus lipid suspension for enema in adult patients with mild to moderately active ulcerative colitis who had an inadequate response or intolerance of at least 1 of aminosalicylates (5-ASAs), corticosteroids, azothiopurine, mercaptopurine and methotrexate and need an alternative therapy. There will be approximately 150 male and female subjects of 18 and 65 years of age enrolled. Patients will be randomized into two groups where Tacrolimus Lipid Suspension for Enema or Placebo (Tacrolimus-free) Lipid Suspension for Enema will be administered rectally once daily for 28 days.
