Gene therapy for rare metabolic disease passes early safety check

NCT ID NCT05506254

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study follows 4 people with methylmalonic acidemia who previously received hLB-001 gene therapy. Researchers are checking for long-term side effects. The goal is to see if the treatment remains safe over time.

What this could mean

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

Active substance
hLB-001 gene therapy
What this could lead to
If successful, this follow-up could show that hLB-001 is safe over the long term, supporting its development as a treatment for methylmalonic acidemia.
What could go wrong
This is a very small, non-interventional study with only 4 participants, so results may not apply to others. It only monitors safety, not effectiveness.
