A Phase 3 Safety and Efficacy Trial of FLT201 Gene Therapy in Patients With Gaucher Disease Type 1

This study is a Phase 3, non-randomized, multicenter, efficacy and safety study in adult patients with Gaucher disease Type 1, on stable treatment with enzyme replacement therapy (ERT) or substrate reduction therapy (SRT) for at least 2 years. The study aims to confirm the efficacy and safety of FLT201 in this population after discontinuation of ERT/SRT.

Inclusion: Aged ≥18 years at time of screening; Clinical diagnosis of Gaucher disease type 1; Stable hemoglobin concentration at baseline; Stable platelet count at baseline; Receiving ERT or SRT without interruption for at least 2 years.

Exclusion: Positive for AAVS3 neutralizing antibodies; History of receiving any gene therapy or cell therapy; Diagnosed or suspected Gaucher disease type 2 or type 3; History of hematopoietic stem cell transplant (HSCT)/bone marrow transplant or any solid organ transplant; History of total splenectomy. Note: Additional protocol defined Inclusion and Exclusion criteria apply; Abnormal lab values, conditions or diseases that would make the participant unsuitable for the study; Positive pregnancy test or lactating.
