Could immune therapy ease nerve pain? new trial tests IVIG for small fiber neuropathy

NCT ID NCT04153422

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

Summary

This study tests whether a drug called IVIG (Panzyga) can help people with small fiber neuropathy, a condition causing nerve pain and damage. Researchers will give 20 adults either IVIG or a placebo for 6 months, then check nerve fiber growth in skin biopsies and pain levels. The goal is to see if IVIG can improve nerve health and reduce symptoms.

What this could mean

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

Active substance

Intravenous immunoglobulin (IVIG) called Panzyga

What this could lead to

If it works, this could point toward a treatment for small fiber neuropathy in people with certain antibodies, potentially reducing pain and improving nerve health.

What could go wrong

This is a small, early-phase trial with only 20 participants, so results may not apply to everyone. IVIG is not yet approved for this condition, and side effects like allergic reactions or kidney issues are possible.
