1 INDICATIONS AND USAGE

Mozobil® (plerixafor) injection 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 (NHL) and multiple myeloma (MM).

Mozobil, a hematopoietic stem cell mobilizer, 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 and multiple myeloma. (1)

2 DOSAGE AND ADMINISTRATION

2.1 Recommended Dosage and Administration

Vials should be inspected visually for particulate matter and discoloration prior to administration and should not be used if there is particulate matter or if the solution is discolored.

Begin treatment with Mozobil after the patient has received G-CSF once daily for four days. [see Dosage and Administration (2.2) ] Administer Mozobil approximately 11 hours prior to initiation of each apheresis for up to 4 consecutive days.

The recommended dose of Mozobil by subcutaneous injection is based on body weight:


Use the patient's actual body weight to calculate the volume of Mozobil to be administered. Each vial delivers 1.2 mL of 20 mg/mL solution, and the volume to be administered to patients should be calculated from the following equation:

0.012 × patient's actual body weight (in kg) = volume to be administered (in mL)

In clinical studies, Mozobil dose has been calculated based on actual body weight in patients up to 175% of ideal body weight. Mozobil dose and treatment of patients weighing more than 175% of ideal body weight have not been investigated.

Based on increasing exposure with increasing body weight, the Mozobil dose should not exceed 40 mg/day. [see Clinical Pharmacology (12.3) ]

2.2 Recommended Concomitant Medications

Administer daily morning doses of G-CSF 10 micrograms/kg for 4 days prior to the first evening dose of Mozobil and on each day prior to apheresis. [see Clinical Studies ]

2.3 Dosing in Renal Impairment

In patients with moderate and severe renal impairment (estimated creatinine clearance (CLCR) ≤ 50 mL/min), reduce the dose of Mozobil by one-third based on body weight category as shown in Table 1. If CLCR is ≤ 50 mL/min the dose should not exceed 27 mg/day, as the mg/kg-based dosage results in increased Mozobil exposure with increasing body weight. [see Clinical Pharmacology (12.3) ] Similar systemic exposure is predicted if the dose is reduced by one-third in patients with moderate and severe renal impairment compared with subjects with normal renal function. [see Clinical Pharmacology (12.3) ]

Estimated Creatinine Clearance

(mL/min)

Dose
Body Weight ≤ 83 kg Body Weight > 83 kg and < 160 kg
> 50 20 mg or 0.24 mg/kg once daily 0.24 mg/kg once daily (not to exceed 40 mg/day)
≤ 50 13 mg or 0.16 mg/kg once daily 0.16 mg/kg once daily (not to exceed 27 mg/day)

The following (Cockroft-Gault) formula may be used to estimate CLCR:

Males:

Creatinine clearance (mL/min) = weight (kg) × (140 – age in years)

72 × serum creatinine (mg/dL)

Females:

Creatinine clearance (mL/min) = 0.85 × value calculated for males

There is insufficient information to make dosage recommendations in patients on hemodialysis.

3 DOSAGE FORMS AND STRENGTHS

Single-use vial containing 1.2 mL of a 20 mg/mL solution.

4 CONTRAINDICATIONS

History of hypersensitivity to Mozobil . Anaphylactic shock has occurred with use of Mozobil.

5 WARNINGS AND PRECAUTIONS

5.1 Anaphylactic shock and Hypersensitivity reactions

Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening with clinically significant hypotension and shock have occurred in patients receiving Mozobil . Observe patients for signs and symptoms of hypersensitivity during and after Mozobil administration for at least 30 minutes and until clinically stable following completion of each administration. Only administer Mozobil when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions.

In clinical studies, mild or moderate allergic reactions occurred within approximately 30 minutes after Mozobil administration in less than 1% of patients .

5.2 Tumor Cell Mobilization in Leukemia Patients

For the purpose of HSC mobilization, 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.

5.3 Hematologic Effects

Leukocytosis

Administration of Mozobil in conjunction with G-CSF increases circulating leukocytes as well as HSC populations. Monitor white blood cell counts during Mozobil use.

Thrombocytopenia

Thrombocytopenia has been observed in patients receiving Mozobil. Monitor platelet counts in all patients who receive Mozobil and then undergo apheresis.

5.4 Potential for Tumor Cell Mobilization

When Mozobil is used 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.

5.5 Splenic Enlargement and Potential for Rupture

Higher absolute and relative spleen weights associated with extramedullary hematopoiesis were observed following prolonged daily Mozobil SC administration in rats at doses approximately 4-fold higher than the recommended human dose based on body surface area. The effect of Mozobil on spleen size in patients was not specifically evaluated in clinical studies. Evaluate individuals receiving Mozobil in combination with G-CSF who report left upper abdominal pain and/or scapular or shoulder pain for splenic integrity.

5.6 Embryo-fetal Toxicity

Mozobil may cause fetal harm when administered to a pregnant woman. Mozobil is teratogenic in animals. There are no adequate and well-controlled studies in pregnant women using Mozobil. Advise women of childbearing potential to avoid becoming pregnant while receiving treatment with Mozobil. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. [see Use In Specific Populations (8.1) ]

6 ADVERSE REACTIONS

The following serious adverse reactions are discussed elsewhere in the labeling:


Most common adverse reactions (≥ 10%): diarrhea, nausea, fatigue, injection site reactions, headache, arthralgia, dizziness, and vomiting. (6)

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The most common adverse reactions (≥ 10%) reported in patients who received Mozobil in conjunction with G-CSF regardless of causality and more frequent with Mozobil than placebo during HSC mobilization and apheresis were diarrhea, nausea, fatigue, injection site reactions, headache, arthralgia, dizziness, and vomiting.

Safety data for Mozobil in combination with G-CSF were obtained from two randomized placebo-controlled studies (301 patients) and 10 uncontrolled studies (242 patients). Patients were primarily treated with Mozobil at daily doses of 0.24 mg/kg SC. Median exposure to Mozobil in these studies was 2 days (range 1 to 7 days).

In the two randomized studies in patients with NHL and MM, a total of 301 patients were treated in the Mozobil 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 micrograms/kg for 4 days prior to the first dose of Mozobil 0.24 mg/kg SC or placebo and on each morning prior to apheresis. The adverse reactions that occurred in ≥ 5% of the patients who received Mozobil regardless of causality and were more frequent with Mozobil than placebo during HSC mobilization and apheresis are shown in Table 2.

In the randomized studies, 34% of patients with NHL or MM had mild to moderate injection site reactions at the site of subcutaneous administration of Mozobil. These included erythema, hematoma, hemorrhage, induration, inflammation, irritation, pain, paresthesia, pruritus, rash, swelling, and urticaria.

Mild to moderate allergic reactions were observed in less than 1% of patients within approximately 30 min after Mozobil administration, including one or more of the following: urticaria (n = 2), periorbital swelling (n = 2), dyspnea (n = 1) or hypoxia (n = 1). Symptoms generally responded to treatments (e.g., antihistamines, corticosteroids, hydration or supplemental oxygen) or resolved spontaneously.

Vasovagal reactions, orthostatic hypotension, and/or syncope can occur following subcutaneous injections. In Mozobil oncology and healthy volunteer clinical studies, less than 1% of subjects experienced vasovagal reactions following subcutaneous administration of Mozobil doses ≤ 0.24 mg/kg. The majority of these events occurred within 1 hour of Mozobil administration. Because of the potential for these reactions, appropriate precautions should be taken.

Other adverse reactions in the randomized studies that occurred in < 5% of patients but were reported as related to Mozobil during HSC mobilization and apheresis included abdominal pain, hyperhidrosis, abdominal distention, dry mouth, erythema, stomach discomfort, malaise, hypoesthesia oral, constipation, dyspepsia, and musculoskeletal pain.

Hyperleukocytosis: In clinical trials, white blood cell counts of 100,000/mcL or greater were observed, on the day prior to or any day of apheresis, in 7% of patients receiving Mozobil and in 1% of patients receiving placebo. No complications or clinical symptoms of leukostasis were observed.

6.2 Post-marketing Experience

In addition to adverse reactions reported from clinical trials, the following adverse reactions have been reported from post-marketing experience with Mozobil. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Immune System Disorders: Anaphylactic reactions, including anaphylactic shock

Psychiatric disorders: Abnormal dreams and nightmares

7 DRUG INTERACTIONS

Based on in vitro data, Mozobil is not a substrate, inhibitor or inducer of human cytochrome P450 isozymes. Mozobil is not likely to be implicated in in vivo drug-drug interactions involving cytochrome P450s. At concentrations similar to what are seen clinically, Mozobil did not act as a substrate or inhibitor of P-glycoprotein in an in vitro study.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category D

Risk Summary

Mozobil may cause fetal harm when administered to a pregnant woman. Mozobil is teratogenic in animals.

Animal Data

Mozobil administered to pregnant rats induced embryo-fetal toxicities including fetal death, increased resorptions and post-implantation loss, decreased fetal weights, anophthalmia, shortened digits, cardiac interventricular septal defect, ringed aorta, globular heart, hydrocephaly, dilatation of olfactory ventricles, and retarded skeletal development. Embryo-fetal toxicities occurred mainly at a dose of 90 mg/m2.

8.3 Nursing Mothers

It is not known whether Mozobil is excreted in human milk. Because many drugs are excreted in human milk, and because of the potential for serious adverse reactions in nursing infants from Mozobil, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

8.4 Pediatric Use

The safety and efficacy of Mozobil in pediatric patients have not been established in controlled clinical studies.

8.5 Geriatric Use

Of the total number of subjects in controlled clinical studies of Mozobil, 24% were 65 and over, while 0.8% were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

Since Mozobil is mainly excreted by the kidney, no dose modifications are necessary in elderly individuals with normal renal function. In general, care should be taken in dose selection for elderly patients due to the greater frequency of decreased renal function with advanced age. Dosage adjustment in elderly patients with CLCR ≤ 50 mL/min is recommended. [see Dosage and Administration and Clinical Pharmacology (12.3) ]

8.6 Renal Impairment

In patients with moderate and severe renal impairment (CLCR ≤ 50 mL/min), reduce the dose of Mozobil by one-third to 0.16 mg/kg. [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ]

10 OVERDOSAGE

Based on limited data at doses above the recommended dose of 0.24 mg/kg SC, the frequency of gastrointestinal disorders, vasovagal reactions, orthostatic hypotension, and/or syncope may be higher.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Mozobil is an inhibitor of the CXCR4 chemokine receptor and blocks binding of its cognate ligand, stromal cell-derived factor-1α. SDF-1α and CXCR4 are recognized to play a role in the trafficking and homing of human hematopoietic stem cells (HSCs) to the marrow compartment. Once in the marrow, stem cell CXCR4 can act to help anchor these cells to the marrow matrix, either directly via SDF-1α or through the induction of other adhesion molecules. Treatment with Mozobil resulted in leukocytosis and elevations in circulating hematopoietic progenitor cells in mice, dogs and humans. CD34+ cells mobilized by Mozobil were capable of engraftment with long-term repopulating capacity up to one year in canine transplantation models.

12.2 Pharmacodynamics

Data on the fold increase in peripheral blood CD34+ cell count (cells/mcL) by apheresis day were evaluated in two placebo-controlled clinical studies in patients with NHL and MM (Study 1 and Study 2, respectively). The fold increase in CD34+ cell count (cells/mcL) over the 24-hour period starting from the day prior to the first apheresis and ending the next morning just before the first apheresis is summarized in Table 3. During this 24-hour period, a single dose of Mozobil or placebo was administered 10 to 11 hours prior to apheresis.

Study Mozobil® and G-CSF Placebo and G-CSF
Median Mean (SD) Median Mean (SD)
Study 1 5.0 6.1 (5.4) 1.4 1.9 (1.5)
Study 2 4.8 6.4 (6.8) 1.7 2.4 (7.3)

In pharmacodynamic studies of Mozobil in healthy volunteers, peak mobilization of CD34+ cells was observed between 6 and 9 hours after administration. In pharmacodynamic studies of Mozobil in conjunction with G-CSF in healthy volunteers, a sustained elevation in the peripheral blood CD34+ count was observed from 4 to 18 hours after Mozobil administration with a peak CD34+ count between 10 and 14 hours.

QT/QTc Prolongation

There is no indication of a QT/QTc prolonging effect of Mozobil in single doses up to 0.40 mg/kg. In a randomized, double-blind, crossover study, 48 healthy subjects were administered a single subcutaneous dose of Mozobil (0.24 mg/kg and 0.40 mg/kg) and placebo. Peak concentrations for 0.40 mg/kg Mozobil were approximately 1.8-fold higher than the peak concentrations following the 0.24 mg/kg single subcutaneous dose.

12.3 Pharmacokinetics

The single-dose pharmacokinetics of Mozobil 0.24 mg/kg were evaluated in patients with NHL and MM following pre-treatment with G-CSF (10 micrograms/kg once daily for 4 consecutive days). Mozobil exhibits linear kinetics between the 0.04 mg/kg to 0.24 mg/kg dose range. The pharmacokinetics of Mozobil were similar across clinical studies in healthy subjects who received Mozobil alone and NHL and MM patients who received Mozobil in combination with G-CSF.

A population pharmacokinetic analysis incorporated Mozobil data from 63 subjects (NHL patients, MM patients, subjects with varying degrees of renal impairment, and healthy subjects) who received a single SC dose (0.04 mg/kg to 0.24 mg/kg) of Mozobil. A two-compartment disposition model with first order absorption and elimination was found to adequately describe the Mozobil concentration-time profile. Significant relationships between clearance and creatinine clearance (CLCR), as well as between central volume of distribution and body weight were observed. The distribution half-life (t1/2α) was estimated to be 0.3 hours and the terminal population half-life (t1/2β) was 5.3 hours in patients with normal renal function.

The population pharmacokinetic analysis showed that the mg/kg-based dosage results in an increased Mozobil exposure (AUC0–24h) with increasing body weight. In order to compare the pharmacokinetics and pharmacodynamics of Mozobil following 0.24 mg/kg-based and fixed (20 mg) doses, a follow-up trial was conducted in patients with NHL (N=61) who were treated with 0.24 mg/kg or 20 mg of Mozobil. The trial was conducted in patients weighing 70 kg or less. The fixed 20 mg dose showed 1.43-fold higher exposure (AUC0–10h) than the 0.24 mg/kg dose (Table 4). The fixed 20 mg dose also showed numerically higher response rate (5.2% [60.0% vs 54.8%] based on the local lab data and 11.7% [63.3% vs 51.6%] based on the central lab data) in attaining the target of ≥ 5 × 106 CD34+ cells/kg than the mg/kg-based dose. However, the median time to reach ≥ 5 × 106 CD34+ cells/kg was 3 days for both treatment groups, and the safety profile between the groups was similar. Based on these results, further analysis was conducted by FDA reviewers and a body weight of 83 kg was selected as an appropriate cut-off point to transition patients from fixed to weight based dosing.

Regimen Geometric Mean AUC
Fixed 20 mg (n=30) 3991.2
0.24 mg/kg (n=31) 2792.7
Ratio (90% CI) 1.43 (1.32,1.54)

There is limited experience with the 0.24 mg/kg dose of Mozobil in patients weighing above 160 kg. Therefore the dose should not exceed that of a 160 kg patient (i.e., 40 mg/day if CLCR is > 50 mL/min and 27 mg/day if CLCR is ≤ 50 mL/min). [see Dosage and Administration (2.1 , 2.3) ]

Absorption

Peak plasma concentrations occurred at approximately 30 – 60 minutes after a SC dose.

Distribution

Mozobil is bound to human plasma proteins up to 58%. The apparent volume of distribution of Mozobil in humans is 0.3 L/kg demonstrating that Mozobil is largely confined to, but not limited to, the extravascular fluid space.

Metabolism

The metabolism of Mozobil was evaluated with in vitro assays. Mozobil is not metabolized as shown in assays using human liver microsomes or human primary hepatocytes and does not exhibit inhibitory activity in vitro towards the major drug metabolizing cytochrome P450 enzymes (1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1 and 3A4/5). In in vitro studies with human hepatocytes, Mozobil does not induce CYP1A2, CYP2B6, or CYP3A4 enzymes. These findings suggest that Mozobil has a low potential for involvement in cytochrome P450-dependent drug-drug interactions.

Elimination

The major route of elimination of Mozobil is urinary. Following a 0.24 mg/kg dose in healthy volunteers with normal renal function, approximately 70% of the dose was excreted in the urine as the parent drug during the first 24 hours following administration. In studies with healthy subjects and patients, the terminal half-life in plasma ranges between 3 and 5 hours. At concentrations similar to what are seen clinically, Mozobil did not act as a substrate or inhibitor of P-glycoprotein in an in vitro study with MDCKII and MDCKII-MDR1 cell models.

Renal Impairment

Following a single 0.24 mg/kg SC dose, Mozobil clearance was reduced in subjects with varying degrees of renal impairment and was positively correlated with CLCR. The mean AUC0–24h of Mozobil in subjects with mild (CLCR 51–80 mL/min), moderate (CLCR 31–50 mL/min), and severe (CLCR < 31 mL/min) renal impairment was 7%, 32%, and 39% higher than healthy subjects with normal renal function, respectively. Renal impairment had no effect on Cmax. A population pharmacokinetic analysis indicated an increased exposure (AUC0–24h) in patients with moderate and severe renal impairment compared to patients with CLCR > 50 mL/min. These results support a dose reduction of one-third in patients with moderate to severe renal impairment (CLCR ≤ 50 mL/min) in order to match the exposure in patients with normal renal function. The population pharmacokinetic analysis showed that the mg/kg-based dosage results in an increased Mozobil exposure (AUC0–24h) with increasing body weight; therefore if CLCR is ≤ 50 mL/min the dose should not exceed 27 mg/day. [see Dosage and Administration (2.3)]

Since Mozobil is primarily eliminated by the kidneys, coadministration of Mozobil with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of Mozobil or the coadministered drug. The effects of coadministration of Mozobil with other drugs that are renally eliminated or are known to affect renal function have not been evaluated.

Race

Clinical data show similar Mozobil pharmacokinetics for Caucasians and African-Americans, and the effect of other racial/ethnic groups has not been studied.

Gender

Clinical data show no effect of gender on Mozobil pharmacokinetics.

Age

Clinical data show no effect of age on Mozobil pharmacokinetics

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies with Mozobil have not been conducted.

Mozobil was not genotoxic in an in vitro bacterial mutation assay (Ames test in Salmonella ), an in vitro chromosomal aberration test using V79 Chinese hamster cells, or an in vivo bone marrow micronucleus test in rats after subcutaneous doses up to 25 mg/kg (150 mg/m2).

The effect of Mozobil on human fertility is unknown. The effect of Mozobil on male or female fertility was not studied in designated reproductive toxicology studies. The staging of spermatogenesis measured in a 28-day repeated dose toxicity study in rats revealed no abnormalities considered to be related to Mozobil. No histopathological evidence of toxicity to male or female reproductive organs was observed in 28-day repeated dose toxicity studies.

14 CLINICAL STUDIES

The efficacy and safety of Mozobil in conjunction with G-CSF in non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM) were evaluated in two placebo-controlled studies (Studies 1 and 2). Patients were randomized to receive either Mozobil 0.24 mg/kg or placebo on each evening prior to apheresis. Patients received daily morning doses of G-CSF 10 micrograms/kg for 4 days prior to the first dose of Mozobil or placebo and on each morning prior to apheresis. Two hundred and ninety-eight (298) NHL patients were included in the primary efficacy analyses for Study 1. The mean age was 55 years (range 29–75) and 58 years (range 22–75) in the Mozobil and placebo groups, respectively, and 93% of subjects were Caucasian. In study 2, 302 patients with MM were included in the primary efficacy analyses. The mean age (58years) and age range (28–75) were similar in the Mozobil and placebo groups, and 81% of subjects were Caucasian.

In Study 1, 59% of NHL patients who were mobilized with Mozobil and G-CSF collected ≥ 5 × 106 CD34+ cells/kg from the peripheral blood in four or fewer apheresis sessions, compared with 20% of patients who were mobilized with placebo and G-CSF (p < 0.001). Other CD34+ cell mobilization outcomes showed similar findings (Table 5).
