Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, multicenter, prospective pilot study of CDX-301 with or without plerixafor as a stem cell mobilizer for allogeneic transplantation (stem cells that come from another person). HLA-matched sibling healthy volunteers (donors) and patients with protocol specified hematologic malignancies (recipients) will be enrolled.
