Arms & Interventions
BEAM-101
BEAM-101 manufactured with autologous CD34+ hematopoietic stem cells collected by plerixafor mobilization and edited ex vivo. No maximum dose has been set for BEAM-101; all of the gene edited cells that pass release specifications will be administered to the patient. BEAM 101 will be administered as a single dose by IV infusion.
Intervention: BEAM-101
