Abstract
High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation is the standard of care for eligible patients with newly diagnosed multiple myeloma leading to prolonged progression free and overall survival. Successful engraftment following hematopoietic stem cell infusion requires adequate stem cell doses. Current mobilization regimens include granulocyte colony-stimulating factor (G-CSF) with or without plerixafor. Motixafortide is a recently approved agent that can be used in combination with G-CSF for mobilization. In the absence of any head-to-head trials comparing the two products, this article aims to outline the similarities and differences of these two agents. Though moxitafortide has a more favorable pharmacokinetic profile in comparison to plerixafor, in clinical trials, the agents demonstrated similar efficacy. In addition, the use of motixafortide in clinical practice may be limited by product cost as well as administration and monitoring requirements.
