This research aims to evaluate how well brenipatide (LY3537031) is tolerated, what side effects may occur, and its safety and effectiveness in adults with Irritable Bowel Syndrome-Diarrhea (IBS-D). The study focuses on participants who meet specific IBS-D criteria related to bowel movement patterns and abdominal pain. It is a Phase 2, randomized, double-blind, placebo-controlled trial lasting approximately 35 weeks. Participants will receive either brenipatide or a placebo, both administered under the skin through subcutaneous injection. The treatments are compared to assess their impact on IBS-D symptoms. The study involves careful monitoring of patients' responses to the medication over the treatment period, with no changes in diet allowed in the four weeks before screening. During the study, participants will track their symptoms daily using an electronic diary, including abdominal pain and stool consistency. Researchers will measure the percentage of days participants have a positive composite response between weeks 9 and 16. Safety and side effects will be monitored throughout the study, ensuring participants are closely observed during the full duration of about 35 weeks.

Researchers are evaluating how effective, safe, and tolerable a vaccine for Clostridioides difficile (C. difficile) infection is in adults aged 65 years and older. The study focuses on reducing the number of C. difficile infections, which can cause diarrhea, in this older adult population. This is a Phase 3, placebo-controlled, double-blinded, randomized trial involving participants who are at risk because of recent or planned contact with healthcare systems or recent antibiotic use. Participants will receive either the C. difficile vaccine or a saline placebo. Both are given by injection into the upper arm muscle. The study includes 3 planned clinic visits and 3 phone visits initially, followed by yearly clinic visits until the study ends. Participants will remain in the study until enough infection events have occurred—this period may last up to about three and a half years, but could be shorter or longer depending on how quickly events happen or if the study stops early due to clear results. Throughout the study, participants will report any side effects such as local reactions and systemic events for 7 days after each vaccination, and adverse events for up to one month. Serious adverse events are monitored for up to 18 months after the last dose. If participants experience 3 or more loose stools within 24 hours during the study, they must save the next stool and contact the study team for infection testing. This ongoing monitoring helps assess the vaccine's impact on preventing medically attended C. difficile infections over time.
