Do you have abdominal pain from Irritable Bowel Syndrome?

You may be eligible for a clinical trial evaluating a medication for IBS-D.

Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Signs and symptoms include cramping, abdominal pain, bloating, gas, and diarrhea or constipation, or both. The key symptom of Irritable Bowel Syndrome is abdominal pain and is associated with a change in the frequency or consistency of stool. IBS-D is a type of IBS in which abdominal pain or bloating symptoms happen along with stools that are often loose or more frequent than usual.

IPS Research is seeking participants for a clinical trial of an investigational medication for the treatment of abdominal pain related to IBS-D in adults.
