The National Institutes of Health (NIH) is offering a federal grant opportunity titled "The NIDDK Disorders of Gastrointestinal Interoception Consortium Clinical Centers (DGIC)." This initiative aims to expand upon the work of the NIDDK Gastroparesis Consortium by establishing a consortium that will include up to six Clinical Research Centers and a Scientific Data Research Center, focusing on disorders of gastrointestinal interoception and their associated symptoms. The program seeks to enhance understanding of gastrointestinal motility disorders, identify biomarkers for treatment efficacy, and leverage advanced technologies for future clinical trials. The estimated total program funding is $1.5 million, with one award expected. Interested applicants can contact Dr. Terez Shea-Donohue at terez.shea-donohue@nih.gov or by phone at 301-825-2314. Key deadlines include an estimated synopsis close date of November 1, 2026, and an estimated award date of July 1, 2027.

The National Institute of Diabetes and Digestive Diseases and Nutrition (NIDDK) seeks to advance its mission by continuing the work of the NIDDK Gastroparesis Consortium (GpCRC) but also to expand its scope. The collaborative efforts of the GpCRC provided a large database, the Gastroparesis Registry, which is located in the NIDDK central repository and contains information on patients with symptoms of either delayed or normal gastric emptying. It also houses the first U.S. registry of children and adolescents with gastroparesis. The GpCRC provided clarity and insight that set the stage for transforming our understanding of gastroparesis and laid out a road map for approaching other disorders of gastrointestinal (GI) motility. The findings from clinical studies and trials clearly demonstrated that the clinical burden of gastroparesis is significantly greater than previously realized and involves much more than the stomach. Importantly, the underlying mechanisms remain unclear.  Interoception is the ability of the nervous system to sense, interpret and coordinate signals from various bodily systems including the GI tract. Many functional GI disorders are associated with a spectrum of overlapping symptoms including nausea, vomiting, and altered bowel habits all of which involve altered interoceptive signaling. This initiative would broaden the scope beyond gastroparesis to include other adult and pediatric GI conditions associated with impaired interoceptive processing to form a Disorders of Gastrointestinal Interoception Consortium (DGIC). The consortium may include up to 6 Clinical Research Centers (described in a companion notice) and a Scientific Data Research Center (SDRC). There would be an emphasis on multidisciplinary approaches that would reveal the underlying mechanisms that connect GI function more directly to symptoms, identify disease or response biomarkers that assess treatment efficacy, and leverage state-of-the-art technologies to identify novel therapeutic targets that could be assessed in future clinical trials. The SDRC will coordinate collaboration among the Clinical Research Centers, participant enrollment, biospecimen collections and processing, and manage the submission of data and samples to central databases and repositories.
