Mitemcinal (GM-611), an erythromycin-derived prokinetic agent, was developed by Chuga as an agonist of the motilin receptor. Mitemcinal acts by a novel mechanism whereby it stimulates and promotes peristalsis in the stomach and other segments of the gastrointestinal tract. This drug was studied as a potential treatment for gastric motility disorder, as well as reflux esophagitis, non-ulcer dyspepsia, and diabetic gastroparesis. Mitemcinal was involved in phase II clinical trials in Patients with diabetic gastroparesis. Although gastroparetic symptoms improved with both mitemcinal and placebo, the prominent placebo effect was not statistically exceeded by mitemcinal. That is why the development of this drug has stalled. In addition, mitemcinal has been studied in phase II for the treatment of irritable bowel syndrome, but this study was also discontinued.
