Plerixafor for Poorly Mobilized Lymphoma

Autologous hematopoietic stem cell transplantation is one of the effective means of lymphoma treatment, but patients who receive transplantation in the absence of sufficient stem cell numbers have a delay in stem cell engraftment and a markedly increased risk of infection and emergence. Plerixafor injection is a strong and specific antagonist of CXCR4. It can rapidly mobilize stem cells from bone marrow into peripheral blood circulation by blocking the combination of SDF1 and CXCR4. Studies have shown that the simultaneous use of plerixafor injection and G-CSF can collect more hematopoietic stem cells in a certain period of time than cancer patients who use G-CSF alone. This multicenter, open-label, single-arm study was designed to evaluate the efficacy and safety of plerixafor injection for hematopoietic stem cell mobilization in poorly mobilized lymphoma patients.
