Prucalopride to help symptoms of diabetic and idiopathic gastroparesis

A multicenter, double-blind, randomized, placebo- controlled, parallel study to assess the efficacy of 5- HT4 agonist prucalopride for the treatment of diabetic and idiopathic gastroparesis

NIH-funded research Texas Tech University Health Sciences Center at El Paso · NIH-11158600

People with diabetic or idiopathic gastroparesis are given prucalopride or a placebo to see if taking prucalopride eases stomach-emptying problems and related symptoms.

What this research studies

If I join, I'll be randomly assigned to receive prucalopride or a placebo and neither I nor the study team will know which I get, with the trial running at multiple clinical centers. Participants are enrolled in a gastroparesis registry where clinical information and blood samples, including peripheral blood mononuclear cells (PBMCs), are collected. Some participants may provide stomach or duodenal brushings during endoscopy, and tissue samples if they undergo relevant surgery, while others may have pyloric function measured with EndoFLIP. The project also completes a related Buspirone treatment arm and follows symptoms, side effects, and objective stomach-emptying tests over time.

Who could benefit from this research

Good fit: Adults diagnosed with diabetic or idiopathic gastroparesis who meet the trial's medical criteria and are willing to attend clinic visits, provide blood samples, and undergo endoscopy-related sampling or other tests are ideal candidates.

Not a fit: People whose gastroparesis has a different known cause, who cannot take prucalopride, or who are unable or unwilling to undergo the required procedures may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this could reduce nausea, vomiting, bloating, and delayed stomach emptying for people with diabetic or idiopathic gastroparesis.

How similar studies have performed: Prucalopride is approved for chronic constipation and small studies suggest it may help stomach motility, but large randomized trials in gastroparesis have been limited.
