Sugar supplement may calm seizures and stomach troubles in rare genetic disease
NCT ID NCT05402384
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study tests whether a sugar called D-galactose (AVTX-801) can help people with SLC35A2-CDG, a rare inherited disorder that disrupts how the body adds sugar to proteins. The trial enrolls about 10 people of any age who have seizures or chronic digestive issues. Participants receive either D-galactose or a placebo in a crossover design, so everyone gets both over time. The goal is to see if the supplement reduces seizure frequency and improves stool consistency.

What this could lead to
If it works, this could point toward a treatment that reduces seizures and digestive problems in people with SLC35A2-CDG.
What could go wrong
This is a small, early-phase trial with only 10 participants, so results may not apply to everyone. The supplement may not improve symptoms or could cause side effects.
