| Type | small molecule |
| Description | Plerixafor 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. |

| Indication | Used 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). |
| Mechanism of action | Plerixafor inhibits the CXCR4 chemokine receptors on CD34+ cells and reversibly blocks binding of the ligand, stromal cell-derived factor-1-alpha (SDF-1?). By blocking the interaction between SDF-1? 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. |
| Absorption | Pharmacokinetic profile follows a two-compartment model with first-order absorption. A median peak plasma concentration of 0.24 mg/kg of plerixafor occurred 30-60 minutes after subcutaneous dose. |
| Protein binding | 58% |
| Biotransformation | Metabolism does not involved CYP isoenzymes |
| Route of elimination | 0.24 mg/kg, healthy subjects: ~70% of the parent drug is excreted in urine in the first 24 hours. |
| Toxicity | LD50, mouse, SC: 16.3 mg/kg; LD50, rat, SC: >50 mg/kg; LD50, mouse and rat, IV injection: 5.2 mg/kg |
