A Phase 2b Study Evaluating Safety and Effectiveness of Camlipixant in Adults Aged 18 to 80 With Diarrhea and Mixed Types of Irritable Bowel Syndrome

What this Trial Is About

Researchers are studying the effects of camlipixant in adults with two types of irritable bowel syndrome IBS-D diarrhea-predominant and IBS-M mixed type. This Phase 2b trial aims to assess how well camlipixant works and how safe it is when compared to a placebo. The study includes two parts, where after the first part, some participants may be randomly assigned to receive a higher dose of camlipixant or stop taking the drug. Participants receive camlipixant at different dose levels or a placebo during the first part of the study. In the second part, all participants are randomized again to either continue with camlipixant or placebo. The treatment lasts up to 26 weeks, with doses adjusted in the second phase. The study uses a triple-blind design where neither participants nor researchers know who receives which treatment during the trial. During the study, participants will regularly report their abdominal pain intensity and stool form using specific scoring systems. Researchers will monitor safety by tracking adverse events and changes in vital signs and laboratory tests. The main outcome measures focus on changes in abdominal pain intensity over weeks 7 to 12. Participants will be assessed throughout the 26-week period to evaluate the treatments effects and safety.
