Gene therapy may free gaucher patients from lifelong infusions
NCT ID NCT07223944
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 6 times
Summary
This Phase 3 trial tests a gene therapy called FLT201 for adults with Gaucher disease type 1. The goal is to see if a single dose can keep blood counts stable so patients can stop their regular enzyme replacement or substrate reduction therapy. The study will enroll 45 people who have been on stable treatment for at least 2 years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FLT201 gene therapy
- What this could lead to
- If it works, this could allow people with Gaucher disease type 1 to stop their regular enzyme or substrate therapy and maintain stable blood counts with a single treatment.
- What could go wrong
- This is still an early Phase 3 trial with only 45 participants. Gene therapy carries risks like immune reactions or the treatment not lasting. Patients must stop their current therapy, which could cause a relapse if FLT201 fails.
