NCT ID NCT04526119

First seen Mar 28, 2026 · Last updated May 14, 2026 · Updated 7 times

Summary

This study tests a medicine called Z-338 in children aged 9 to 17 who have functional dyspepsia, a condition causing stomach pain and fullness after eating. The trial has two parts: first, a single dose to measure how the body processes the drug, then a 28-day treatment period where some children receive the drug and others a placebo. The goal is to see if Z-338 safely reduces symptoms like bloating and early fullness.
