Study of Safety and Efficacy of Genome-edited Hematopoietic Stem and Progenitor Cells in Sickle Cell Disease (SCD)

Summary

This study evaluated a genome-edited, autologous, hematopoietic stem and progenitor cell (HSPC) product - OTQ923 to reduce the biologic activity of BCL11A, increasing fetal hemoglobin (HbF) and reducing complications of sickle cell disease.
