GroβT rapidly and reliably mobilizes primitive hematopoietic stem and progenitor cells in nonhuman primates.

ABSTRACT: Autologous hematopoietic stem cell (HSC) gene therapy has gone through remarkable advancements in recent years, especially for the treatment of sickle cell disease (SCD). However, the collection of HSCs from SCD patients requires unique considerations, as granulocyte colony-stimulating factor (G-CSF)-mediated mobilization is contraindicated, and plerixafor-only mobilization is highly variable. Consequently, alternative mobilization regimens that are safe for SCD patients and generate better cell yields are desirable for SCD HSC gene therapy. Here, we evaluated a combination of plerixafor (AMD3100, a CXCR4 antagonist) with GroβT (MGTA-145/GroβT, a CXCR2 agonist) against the current gold-standard G-CSF for HSC gene therapy in nonhuman primates (NHPs) for HSC mobilization, leukapheresis, e
