ClinConnect Summary
This clinical trial is studying a new treatment called CMTS4520, which is a type of dietary fiber probiotic, to see if it can help adults who suffer from chronic constipation. Chronic constipation is when a person has difficulty passing stools and goes to the bathroom less than three times a week. To be eligible for this trial, participants need to be between 18 and 70 years old and have experienced chronic constipation for at least six months, with symptoms like hard or dry stools.
Before joining the trial, potential participants will need to pass a series of health checks to ensure they don’t have certain medical conditions that could interfere with the study. This includes not having specific digestive issues, recent surgeries, or serious heart and lung problems. If someone is eligible and decides to join, they will be helping researchers learn more about how effective and safe CMTS4520 is for treating chronic constipation. The trial is currently not recruiting participants, so it’s important to keep an eye on updates if you or someone you know is interested in participating.
