New antibody drug could reduce infusions for nerve disorder

NCT ID NCT05225675

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests an experimental drug called ARGX-117 in 54 adults with multifocal motor neuropathy (MMN), a condition that causes muscle weakness. Participants receive either ARGX-117 or a placebo by IV, and researchers check if the drug can safely delay the need for standard IVIg treatments. The goal is to see if ARGX-117 can help control the disease with fewer infusions.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

ARGX-117 (an experimental antibody given intravenously)

What this could lead to

If it works, this could point toward a new treatment that reduces the need for regular IVIg infusions in people with multifocal motor neuropathy.

What could go wrong

This is a small, early-phase trial with only 54 participants. The drug may not work better than placebo, and side effects are still being studied.
