Mozobil (plerixafor injection) is indicated in combination with granulocyte-colony stimulating factor (G-CSF) 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).

Important Safety Information

Mozobil may cause mobilization of leukemic cells and subsequent contamination of the apheresis product. Therefore, Mozobil is not intended for HSC mobilization and harvest in patients with leukemia.
Mozobil in conjunction with G-CSF increases circulating leukocytes and HSC populations. White blood cell counts should be monitored during treatment. Clinical judgment should be exercised when administering Mozobil to patients with peripheral white blood cell counts above 50,000/mcL.
Thrombocytopenia has been observed in patients receiving Mozobil. Platelet counts should be monitored in patients who receive Mozobil and then undergo apheresis.
In patients treated with Mozobil in combination with G-CSF for HSC mobilization‚ tumor cells may be released from the marrow and subsequently collected in the leukapheresis product. The effect of potential reinfusion of tumor cells has not been well-studied.
The effect of Mozobil on spleen size was not specifically evaluated in clinical studies. Individuals receiving Mozobil in combination with G-CSF who report left upper abdominal pain and/or scapular or shoulder pain should be evaluated for splenic integrity.
Mozobil may cause fetal harm when administered to a pregnant woman. Plerixafor was teratogenic in animals. There are no adequate and well-controlled studies in pregnant women using Mozobil. Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with Mozobil.
The most common adverse reactions (≥10%) during HSC mobilization and apheresis were: diarrhea (37%), nausea (34%), fatigue (27%), injection site reaction (34%), headache (22%), arthralgia (13%), dizziness (11%), and vomiting (10%). The majority of these adverse reactions were Grade 1 and 2.
