Clinical Trials: New Open Studies and Surveys for Irritable Bowel Syndrome (IBS) in the U.S., Canada and U.K. January 2014

Below are a few of the studies that have come to the attention of IBS Impact recently through various sources. In some cases, the description below is a summary of major qualifications and details available, and other restrictions may apply.  If interested, please contact each listed sponsor or study site directly for further information.

Imaging Study on the Brain, the Gut and the Microbiome,  UCLA Center for Neurobiology of Stress

“The purpose of this study is to examine brain networks at rest in chronic pain conditions compared to healthy controls.” This is an on-site study, so volunteers must be able to visit the Center, which is a major research institution involved in the study of IBS and other neurologically-based chronic pain conditions. The primary investigator is Emeran Mayer, MD, Director of the UCLA Center for Neurovisceral Sciences, Co-founder of the UCLA Collaborative Centers for Integrative Medicine, and Professor at UCLA’s David Geffen School of Medicine. This study is seeking men and women who are ages 18-55, right handed, not pregnant, have a formal diagnosis of irritable bowel syndrome (IBS), and no significant neurological or psychological medical history. Participation involves one screening visit to the Center, an MRI and a stool sample. Volunteers who complete the study may receive up to $100 and a digital picture of their own brain. For further information, call (310) 206-1758

The above information was received from various social media sources and is summarized from the Center website.
