- Background
Plerixafor is a small-molecule inhibitor of C-X-C chemokine receptor type 4 (CXCR4) that acts as a hematopoietic stem cell mobilizer.5,9 It is used to stimulate the release of stem cells from the bone marrow into the blood in patients with non-Hodgkin's lymphoma (NHL) and multiple myeloma to stimulate their immune system. These stem cells are then collected and used in autologous stem cell transplantation to replace blood-forming cells destroyed by chemotherapy.6,9
As an inhibitor of CXCR4, plerixafor blocks the binding of its ligand, stromal cell-derived factor-1-alpha (SDF-1α). Since CXCR4 and SDF-1α are involved in the trafficking and homing of CD34+ cells to the marrow compartment, blocking this interaction leads to an increase in CD34+ cell circulating levels.5 Compared to placebo with G-CSF, the plerixafor and G-CSF mobilization regimen has a higher probability of achieving the optimal CD34+ cell target for tandem transplantation in fewer apheresis procedures.3
Plerixafor has orphan drug status in the United States and European Union and was approved by the US Food and Drug Administration on December 15, 2008.5,9

Pharmacology
- Indication
Plerixafor is indicated in combination with granulocyte-colony stimulating factor (G-CSF) to mobilize hematopoietic stem cells (HSCs) to the peripheral blood for collection and subsequent autologous transplantation in patients with non-Hodgkin’s lymphoma or multiple myeloma.9

- Pharmacodynamics
Plerixafor is a bicyclam derivative that antagonizes C-X-C chemokine receptor type 4 (CXCR4) by binding to three acidic residues in the ligand-binding pocket: Asp171, Asp262, and Glu288.7,10 Blood levels of CD34+ cells peaked between 6 and 9 hours after the administration of 0.24 mg/kg plerixafor in healthy subjects. In combination with a granulocyte-colony stimulating factor (G-CSF), circulating CD34+ cells in the peripheral blood peaked between 10 and 14 hours. The use of plerixafor is not associated with QT/QTc prolongation at single doses up to 0.40 mg/kg.9
Serious hypersensitivity reactions, such as anaphylactic-type reactions, have occurred in patients receiving plerixafor. The use of plerixafor may also cause tumor cell mobilization in leukemia patients, splenic enlargement and rupture, embryo-fetal toxicity, and hematologic effects, such as leukocytosis and thrombocytopenia. When used in combination with G-CSF for hematopoietic stem cell mobilization‚ plerixafor may lead to the release of tumor cells from the marrow and their subsequent collection in the leukapheresis product.9
- Mechanism of action
Plerixafor inhibits the C-X-C chemokine receptor type 4 (CXCR4) on CD34+ cells and reversibly blocks the binding of its ligand, stromal cell-derived factor-1-alpha (SDF-1α). SDF-1α and CXCR4 play a role in the trafficking and homing of human hematopoietic stem cells (HSCs) to the marrow compartment. In the marrow, stem cell CXCR4 can help anchor HSCs to the marrow matrix, either directly via SDF-1α or through the induction of other adhesion molecules. By blocking the interaction between SDF-1α and CXCR4 with plerixafor, the mobilization of progenitor cells is triggered. Adding granulocyte-colony stimulating factor (G-CSF) to enhance CD34+ cell mobilization increases the yield of stem cells, an important determinant of graft adequacy.1,2,9
Target Actions Organism AC-X-C chemokine receptor type 4 antagonistinhibitorHumans - Absorption
Plerixafor follows a two-compartment pharmacokinetic profile with first-order absorption and exhibits linear kinetics between 0.04 mg/kg and 0.24 mg/kg. The pharmacokinetic profile of plerixafor in healthy subjects was similar to the one observed in patients with non-Hodgkin’s lymphoma (NHL) and multiple myeloma (MM) who received plerixafor in combination with granulocyte-colony stimulating factor (G-CSF). In addition, the clearance of plerixafor has a significant relationship with creatinine clearance (CLCR). The population pharmacokinetic analysis showed that, with increasing body weight, a mg/kg-based dosage leads to a higher plerixafor exposure (AUC0-24h). However, NHL patients (<70 kg) given a fixed dose of 20 mg of plerixafor had an AUC0-10h 1.43-fold higher than the one detected in patients given 0.24 mg/kg of plerixafor. Therefore, a body weight of 83 kg was selected as an appropriate cut-off point to transition patients from fixed to weight-based dosing.9
Peak concentrations are reached in approximately 30-60 minutes (tmax) following subcutaneous injection.9,10 In patients given 0.24 mg/kg of plerixafor subcutaneously after receiving 4-days of G-CSF pre-treatment, the Cmax and AUC0-24 were 887 ng/ml and 4337 ng·hr/ml, respectively.10
- Volume of distribution
Plerixafor has an apparent volume of distribution of 0.3 L/kg.9
- Protein binding
The human plasma protein binding of plerixafor is up to 58%.9
- Metabolism
Plerixafor is not metabolized by the liver and is not a metabolism-dependent inhibitor of major cytochrome P450 enzymes, including 1A2, 2C9, 2C19, 2D6 and 3A4. In addition, it does not induce cytochrome P450 1A2, 2B6, or 3A4 enzymes.9 Plerixafor is metabolically stable, and in vivo studies in rats and dogs showed that the non-parent radiolabelled components in plasma and urine were Cu2+ complexes with plerixafor. This is consistent with the presence of two cyclam rings in plerixafor, which may act as potential chelating sites.13
- Route of elimination
Plerixafor is mainly eliminated through urine. In healthy volunteers with normal renal function given 0.24 mg/kg of plerixafor, approximately 70% of the parent drug is excreted in urine in the first 24 hours. An in vitro study with MDCKII and MDCKII-MDR1 cell models found that plerixafor is not a substrate or inhibitor of P-glycoprotein.9
- Half-life
Plerixafor has a distribution half-life of 0.3 hours and a terminal population half-life of 5.3 hours in patients with normal renal function. In studies with healthy subjects and patients, the terminal half-life in plasma ranges between 3 and 5 hours.9 In patients with non-Hodgkin lymphoma, the terminal half-life of plerixafor is 4.4 hours, and in patients with multiple myeloma, the terminal half-life is 5.6 hours.4
- Clearance
Plerixafor has a total plasma clearance of 4.38 L/h, and a renal clearance of 3.15 L/h.4,8

- Toxicity
There is limited data about the effects of plerixafor at doses higher than the recommended (0.24 mg/kg subcutaneously). However, the frequency of gastrointestinal disorders, vasovagal reactions, orthostatic hypotension, and/or syncope may be higher.9 The carcinogenicity of plerixafor has not been evaluated, and the effect of plerixafor on human fertility is unknown. According to the results from an in vitro bacterial mutation assay, an in vitro chromosomal aberration test, and an in vivo bone marrow micronucleus test in rats after subcutaneous doses up to 25 mg/kg, plerixafor is not genotoxic.9 In mice and rats, the LD50 of plerixafor by intravenous injection is 5 mg/kg. The LD50 of plerixafor by subcutaneous injection is 16 mg/kg in mice and >50 mg/kg in rats/.11
