A Phase 2 Study to Evaluate Safety and Effectiveness of Brenipatide for Adults With Irritable Bowel Syndrome-Constipation IBS-C

What this Trial Is About

Researchers are evaluating how well brenipatide LY3537031 is tolerated, its side effects, and its safety and effectiveness in adults with Irritable Bowel Syndrome-Constipation IBS-C. This Phase 2 study compares brenipatide given under the skin with a placebo to better understand its impact on IBS-C symptoms. The trial is sponsored by Eli Lilly and Company and lasts about 35 weeks. Participants will receive either brenipatide or a placebo, both administered subcutaneously. The study uses a randomized, double-blind, placebo-controlled design with parallel groups. Treatment effects will be measured primarily between weeks 9 and 16, focusing on the weekly composite clinical response. Secondary outcomes include abdominal pain and bowel movement responses during the same period. During the study, participants will be monitored for safety and symptom changes. They will record abdominal pain scores daily and bowel habits using a stool form scale. Researchers will review these data along with other health assessments to evaluate the study drugs effects. The total participation duration is approximately 35 weeks, including screening, treatment, and follow-up periods.
