Official title: Advancing Science for the Diagnosis and Treatment of Gastroparesis

Funded at Mayo Clinic Arizona · NIH-11161590 · Data updated 2026-11-12

This project will grow a patient registry and test whether the drug pioglitazone can help adults with gastroparesis and related functional dyspepsia.

Who could benefit from this research

Could help

Adults with diagnosed gastroparesis or persistent functional dyspepsia symptoms (chronic nausea, vomiting, early satiety, postprandial fullness, or related abdominal pain) are the likely candidates.

Less likely to help

Children, people without gastroparesis or functional dyspepsia, or individuals with medical contraindications to pioglitazone may not benefit from this project.

What this research studies

From a patient's perspective, the team will finish ongoing clinical studies coordinated by the Gastroparesis Clinical Research Consortium, start a larger gastroparesis registry that includes more people with idiopathic functional dyspepsia, and run a clinical study of pioglitazone to see if it affects immune activity linked to stomach nerve problems. The registry will collect medical information and samples to better understand symptom patterns and disease causes. The pioglitazone work will examine whether calming certain immune cells (macrophages) can improve gastric function and symptoms. Together these efforts aim to speed diagnosis and lead to better, more targeted treatments.

Why it matters

Potential benefit: If successful, this work could lead to clearer diagnoses, new treatment options such as pioglitazone for some patients, and more personalized care plans.

How similar studies have gone: Previous consortium studies have improved understanding of gastroparesis, but using pioglitazone to target macrophage-related damage in humans is relatively novel and not yet proven in large trials.
