DescriptionPlerixafor is a hematopoietic stem cell mobilizer. It is used to stimulate the release of stem cells from the bone marrow into the blood in patients with non-Hodgkin lymphoma and multiple myeloma for the purpose of stimulating the immune system. These stem cells are then collected and used in autologous stem cell transplantation to replace blood-forming cells that were destroyed by chemotherapy. Plerixafor has orphan drug status in the United States and European Union; it was approved by the U.S. Food and Drug Administration on December 15, 2008.

IndicationUsed in combination with granulocyte-colony stimulating factor (G-CSF, filgrastim) to mobilize hematopoietic stem cells to the peripheral blood for collection and subsequent autologous transplantation in patients with non-Hodgkin’s lymphoma (NHL) and multiple myeloma (MM).
Structured Indications Not Available
PharmacodynamicsPlerixafor is a bicyclam derivative that antagonizes CXCR4 by binding to three acidic residues in the ligand-binding pocket: Asp171, Asp262, and Glu288. Blood levels of CD34+ cells peaked at 9 hours after administration of 0.24 mg/kg plerixafor in healthy subjects. In patients that have non-Hodgkin’s lymphoma or multiple myeloma, blood levels of CD34+ peaked at 6 hours. In combination with a G-CSF, circulating CD34+ cells in the peripheral blood peaked at 9-14 hours.
Mechanism of actionPlerixafor inhibits the CXCR4 chemokine receptors on CD34+ cells and reversibly blocks binding of the ligand, stromal cell-derived factor-1-alpha (SDF-1α). By blocking the interaction between SDF-1α and CXCR4 with plerixafor, mobilization of progenitor cells is triggered. Filgrastim, a granulocyte-colony stimulating factor, is added to enhance CD34+ cell mobilization, thus increasing the yield of stem cells- an important determinant of graft adequacy.

General Function:
Virus receptor activity
Specific Function:
Receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. Acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Involved in hematopoiesis and in cardiac ventricular septum formation. Also plays an essential role in vasculari...
