A Study Evaluating Gene Therapy With BB305 Lentiviral Vector in Sickle Cell Disease (NCT04293185)
A Phase 3 Study Evaluating Gene Therapy by Transplantation of Autologous CD34+ Stem Cells Transduced Ex Vivo With the BB305 Lentiviral Vector in Subjects With Sickle Cell Disease
🩺 Plain-English Summary (8th-Grade Level)
This is a non-randomized, open-label, multi-site, single-dose, Phase 3 study in approximately 35 adults and pediatric subjects ≥2 and ≤50 years of age with sickle cell disease (SCD). The study will evaluate hematopoietic stem cell (HSC) transplantation (HSCT) using bb1111 (also known as LentiGlobin BB305 Drug Product for SCD).
