FANCA Gene Transfer for Fanconi Anemia Using a High-safety, High-efficiency, Self-inactivating Lentiviral Vector

Plain-language summary

This study examines a gene therapy in which the FANCA gene is delivered into the patient's own stem cells using a self-inactivating lentiviral vector, for patients with FANCA-type Fanconi anemia. It enrolls patients aged 4 and older whose FANCA-type Fanconi anemia is confirmed by DNA sequencing. The trial is a non-phase study and is currently recruiting.

The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
