Are you or a loved one suffering from the abdominal (belly) pain and discomfort, abnormal bowel habits, and bloating of Irritable Bowel Syndrome with Diarrhea (IBS-D)?

Right now, clinical research doctors are seeking volunteers for an investigational drug study in your area to learn how it affects people with IBS-D. Qualified study volunteers may receive the following at no cost: 

•               Investigational drug for Irritable Bowel Syndrome with Diarrhea

•               Study-related care from a local doctor

•               Compensation for time and travel

To qualify, you must be 18 to 65 years of age, living with IBS-D for at least 6 months, and have no history of inflammatory or immune-mediated GI disorders including, but not limited to, inflammatory bowel disease (Crohn’s disease, ulcerative colitis, microscopic colitis, and celiac disease). Study doctors will help determine if this study is right for you.
