Plerixafor Accord therapy should be initiated and supervised by a physician experienced in oncology and/or haematology. The mobilisation and apheresis procedures should be performed in collaboration with an oncology-haematology centre with acceptable experience in this field and where the monitoring of haematopoietic progenitor cells can be correctly performed.
Age over 60 and/ or prior myelosuppressive chemotherapy and/or extensive prior chemotherapy and/or a peak circulating stem cell count of less than 20 stem cells/microliter, have been identified as predictors of poor mobilisation. 2).
24 mg/kg of body weight for patients weighing > 83 kg. 1). 2 ml of 20 mg/ml plerixafor aqueous solution for injection containing 24 mg of plerixafor. Plerixafor has to be drawn up into a syringe size type which should be selected according to the weight of the patient.
For low weight patients, up to 45 kg of body weight, 1 ml syringes for use in infant patients can be used. 01 ml and therefore is suitable to administer plerixafor, at a dose of 240 μg/kg, to paediatric patients of at least 9 kg body weight.
1 ml to be measured can be used. It should be administered by subcutaneous injection 6 to 11 hours prior to initiation of each apheresis following 4 day pre-treatment with G-CSF. In clinical trials, plerixafor has been commonly used for 2 to 4 (and up to 7) consecutive days.
The weight used to calculate the dose of plerixafor should be obtained within 1 week before the first dose of plerixafor. In clinical studies, the dose of plerixafor has been calculated based on body weight in patients up to 175% of ideal body weight.
Plerixafor dose and treatment of patients weighing more than 175% of ideal body weight have not been investigated. 394) – 60). Based on increasing exposure with increasing body weight, the plerixafor dose should not exceed 40 mg/day.
Recommended concomitant medicinal products In pivotal clinical studies supporting the use of Plerixafor treatment, all patients received daily morning doses of 10 μg/kg G-CSF for 4 consecutive days prior to the first dose of plerixafor and on each morning prior to apheresis.
2). Clinical data with this dose adjustment are limited. There is insufficient clinical experience to make alternative posology recommendations for patients with a creatinine clearance <20 ml/min, as well as to make posology recommendations for patients on haemodialysis.
Summary of the safety profile Safety data for plerixafor in conjunction with G-CSF in oncology patients with lymphoma and multiple myeloma were obtained from 2 placebo-controlled Phase III studies (301 patients) and 10 uncontrolled phase II studies (242 patients).
24 mg/kg plerixafor by subcutaneous injection. The exposure to plerixafor in these studies ranged from 1 to 7 consecutive days (median = 2 days). In the two phase III studies in non-Hodgkin’s lymphoma and multiple myeloma patients (AMD3100-3101 and AMD3100-3102, respectively), a total of 301 patients were treated in the Plerixafor and G-CSF group and 292 patients were treated in the placebo and G-CSF group.
Patients received daily morning doses of G-CSF 10 μg/kg for 4 days prior to the first dose of plerixafor or placebo and on each morning prior to apheresis. Adverse reactions that occurred more frequently with Plerixafor and G-CSF than placebo and G-CSF and were reported as related in ≥1% of the patients who received Plerixafor, during haematopoietic stem cell mobilisation and apheresis and prior to chemotherapy/ablative treatment in preparation for transplantation are shown in Table 1.
From chemotherapy/ablative treatment in preparation of transplantation through 12 months post- transplantation, no significant differences in the incidence of adverse reactions were observed across treatment groups. Tabulated list of adverse reactions Adverse reactions are listed by System Organ Class and frequency.

Tumour cell mobilisation in patients with lymphoma and multiple myeloma When Plerixafor treatment is used in conjunction with G-CSF for haematopoietic stem cell mobilisation in patients with lymphoma or multiple myeloma‚ tumour cells may be released from the marrow and subsequently collected in the leukapheresis product.
Results showed that, in case tumour cells are mobilised, the number of tumour cells mobilised is not increased upon plerixafor plus G-CSF compared to G-CSF alone. Tumour cell mobilisation in leukaemia patients In a compassionate use programme, Plerixafor treatment and G-CSF have been administered to patients with acute myelogenous leukaemia and plasma cell leukaemia.
In some instances, these patients experienced an increase in the number of circulating leukaemia cells. For the purpose of haematopoietic stem cell mobilisation, plerixafor may cause mobilisation of leukaemic cells and subsequent contamination of the apheresis product.
Therefore, plerixafor is not recommended for haematopoietic stem cell mobilisation and harvest in patients with leukaemia. Haematological effects Hyperleukocytosis Administration of Plerixafor treatment in conjunction with G-CSF increases circulating leukocytes as well as haematopoietic stem cell populations.
White blood cell counts should be monitored during plerixafor therapy. Clinical judgment should be exercised when administering Plerixafor treatment to patients with peripheral blood neutrophil counts above 50 x 109/L. Thrombocytopenia Thrombocytopenia is a known complication of apheresis and has been observed in patients receiving Plerixafor treatment.
Platelet counts should be monitored in all patients receiving Plerixafor treatment and undergoing apheresis. 8). , antihistamines, corticosteroids, hydration or supplemental oxygen) or resolved spontaneously. Cases of anaphylactic reactions, including anaphylactic shock, have been reported from world-wide post-marketing experience.

Based on increasing exposure with increasing body weight the dose should not exceed 27 mg/day if the creatinine clearance is lower than 50 ml/min. 2). Elderly patients (> 65 years old) No dose modifications are necessary in elderly patients with normal renal function.
Dose adjustment in elderly patients with creatinine clearance ≤ 50 ml/min is recommended (see Renal impairment above). In general, care should be taken in dose selection for elderly patients due to the greater frequency of decreased renal function with advanced age.
Method of administration Plerixafor Accord is for subcutaneous injection. Each vial is intended for single use only. Vials should be inspected visually prior to administration and not used if there is particulate matter or discolouration.
3).
Events included one or more of the following: urticaria (n = 2), periorbital swelling (n = 2), dyspnoea (n = 1) or hypoxia (n = 1). These events were generally mild or moderate and occurred within approximately 30 min after Plerixafor administration.
** From post-marketing experience The adverse reactions reported in patients with lymphoma and multiple myeloma who received Plerixafor in the controlled Phase III studies and uncontrolled studies, including a Phase II study of Plerixafor as monotherapy for haematopoietic stem cell mobilisation, are similar.
No significant differences in the incidence of adverse reactions were observed for oncology patients by disease, age, or gender. Description of selected adverse reactions Myocardial infarction In clinical studies, 7 of 679 oncology patients experienced myocardial infarctions after haematopoieticstem cell mobilisation with plerixafor and G-CSF.
All events occurred at least 14 days after last plerixafor administration. Additionally, two female oncology patients in the compassionate use programme experienced myocardial infarction following haematopoietic stem cell mobilisation with plerixafor and G-CSF.
One of these events occurred 4 days after last plerixafor administration. Lack of temporal relationship in 8 of 9 patients coupled with the risk profile of patients with myocardial infarction does not suggest Plerixafor confers an independent risk for myocardial infarction in patients who also receive G-CSF.
Hyperleukocytosis White blood cell counts of 100 x 109/L or greater were observed, on the day prior to or any day of apheresis, in 7% patients receiving Plerixafor and in 1% patients receiving placebo in the Phase III studies. No complications or clinical symptoms of leukostasis were observed.
24 mg/kg. The majority of these events occurred within 1 hour of plerixafor administration. Gastrointestinal disorders In Plerixafor clinical studies of oncology patients, there have been rare reports of severe gastrointestinal events, including diarrhoea, nausea, vomiting, and abdominal pain.
8 Paraesthesia Paraesthesia is commonly observed in oncology patients undergoing autologous transplantation following multiple disease interventions. 2% in the plerixafor and placebo groups, respectively. Elderly patients In the two placebo-controlled clinical studies of plerixafor, 24% of patients were ≥ 65 years old.
No notable differences in the incidence of adverse reactions were observed in these elderly patients when compared with younger ones. 1). The safety profile in this paediatric […]
Appropriate precautions should be taken because of the potential for these reactions. 8). Appropriate precautions should be taken because of the potential for these reactions. Effect on the spleen In preclinical studies, higher absolute and relative spleen weights associated with extramedullary haematopoiesis were observed following prolonged (2 to 4 weeks) daily plerixafor subcutaneous administration in rats at doses approximately 4 fold higher than the recommended human dose.
The effect of plerixafor on spleen size in patients has not been specifically evaluated in clinical studies. Cases of splenic enlargement and/or rupture have been reported following the administration of Plerixafor treatment in conjunction with growth factor G-CSF.
Individuals receiving Plerixafor treatment in conjunction with G-CSF who report left upper abdominal pain and/or scapular or shoulder pain should be evaluated for splenic integrity.
