Gene Therapy Trial for Gaucher Disease Type 1 with FLT201

This study is testing a gene therapy called FLT201 for adults with Gaucher disease Type 1. FLT201 is a special type of virus that delivers genetic material. The goal is to see how well FLT201 works and if it's safe, especially after people stop their current enzyme replacement therapy (ERT) or substrate reduction therapy (SRT). You might be able to join if you are at least 18 years old, have Gaucher disease Type 1, and have been on stable ERT or SRT for at least two years. We will know if FLT201 is effective after one year. The study plans to enroll 45 participants, but the current recruitment status is unclear.

Study design
This is a Phase 3 study, meaning it's in a later stage of testing, and it's not randomized. It will involve multiple centers and plans to enroll 45 adult participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The primary goal is to evaluate the efficacy of FLT201 at 1 year, suggesting follow-up for at least this duration.
