The Gastroparesis Clinical Research Consortium  (GpCRC) is sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to focus on the etiology, natural history, and therapy of gastroparesis. The goal of this consortium is to perform clinical, epidemiological, and therapeutic research in gastroparesis and provide an infrastructure that can rapidly and efficiently design and conduct clinical trials for effective medical, surgical, or other interventions to improve treatment of patients with gastroparesis.
