Gene therapy aims to halt fatal brain disease in children

NCT ID NCT03725670

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

Summary

This trial tests a gene therapy for metachromatic leukodystrophy (MLD), a rare and life-threatening genetic disorder that damages the nervous system. The treatment uses a lentivirus to deliver a working copy of the ARSA gene directly into the spinal fluid and bloodstream. Up to 10 participants, including infants as young as 1 month, will be monitored for safety and any changes in disease progression.

What this could mean

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

Active substance

lentiviral TYF-ARSA gene therapy

What this could lead to

If successful, this could slow or stop the progression of MLD, a severe genetic disorder, by correcting the underlying enzyme deficiency.

What could go wrong

This is an early-phase trial with only 10 participants, so results may not apply broadly. Gene therapy carries risks like immune reactions or off-target effects.
