Motixafortide and Natalizumab to Mobilize CD34+ Hematopoietic Stem Cells for Gene Therapies in Sickle Cell Disease (SCD)
Hematopoietic stem cell (HSC)-based gene therapies now offer curative potential for patients with sickle cell disease (SCD), with decreased toxicity compared to allogeneic hematopoietic cell transplantation. However, effective HSC-based gene therapy depends on collecting sufficient HSCs to generate the therapeutic product, and currently available mobilization regimens carry unacceptable risk for patients with SCD or do not reliably yield optimal numbers of HSCs for gene therapy.
