ReviewHematopoietic effects and clinical uses of granulocyte-macrophage colony-stimulating factor and PIXY321.
The clinical uses of granulocyte-macrophage colony-stimulating factor (GM-CSF) are expanding. GM-CSF was originally approved for use after autologous bone marrow transplantation. More recent phase III studies using GM-CSF after allogenic marrow transplantation show a similar reduction in the duration of neutropenia and monocytopenia. ⋯ PIXY321 is a fusion protein of GM-CSF and interleukin-3. PIXY321 was developed, in part, because in vitro and in vivo laboratory studies suggested synergy between its two components. Phase I-II clinical studies using PIXY321 are preliminary but show encouraging results with stimulation of multilineage hematopoiesis.
