Ex vivo expanded human myeloid progenitor cells (hMPCs; CLT-008) have the potential to accelerate neutrophil recovery in patients receiving myeloablative conditioning as part of an umbilical cord blood transplant for hematologic cancer. In this study, the safety and tolerability of CLT-008 administered 24 hours after an umbilical cord blood transplant will be determined by monitoring for adverse reactions, neutrophil and platelet recovery, hematopoietic chimerism, graft-versus-host disease (GVHD), and infections.

Condition Intervention Phase
Multiple Myeloma
Plasma Cell Neoplasm
Myelodysplastic Syndromes
Biological: human myeloid progenitor cells
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: A Phase I Trial to Determine Safety and Tolerability of Ex Vivo Expanded Human Myeloid Progenitor Cells (CLT-008) Infused 24 Hours Post-Transplant to Support Allogeneic Umbilical Cord Blood Transplantation for Hematologic Malignancies
