Adverse Reactions in Patients with Cancer Receiving Myelosuppressive Chemotherapy The following adverse reaction data in Table 2 are from three randomized, placebo-controlled studies in patients with: • small cell lung cancer receiving standard dose chemotherapy with cyclophosphamide‚ doxorubicin‚ and etoposide (Study 1) • small cell lung cancer receiving ifosfamide, doxorubicin‚ and etoposide (Study 2), and • non-Hodgkin's lymphoma (NHL) receiving doxorubicin, cyclophosphamide, vindesine, bleomycin, methylprednisolone, and methotrexate ("ACVBP") or mitoxantrone, ifosfamide, mitoguazone, teniposide, methotrexate, folinic acid, methylprednisolone, and methotrexate ("VIM3") (Study 3). A total of 451 patients were randomized to receive subcutaneous filgrastim 230 mcg/m 2 (Study 1), 240 mcg/m 2 (Study 2) or 4 or 5 mcg/kg/day (Study 3) (n = 294) or placebo (n = 157). The patients in these studies were median age 61 (range 29 to 78) years and 64% were male. The ethnicity was 95% Caucasian, 4% African American, and 1% Asian. Table 2. Adverse Reactions in Patients with Cancer Receiving Myelosuppressive Chemotherapy (With ≥ 5% Higher Incidence in Filgrastim Compared to Placebo) System Organ Class Preferred Term Filgrastim (N = 294) Placebo (N = 157) Blood and lymphatic system disorders Thrombocytopenia 38% 29% Gastrointestinal disorders Nausea 43% 32% General disorders and administration site conditions Pyrexia 48% 29% Chest pain 13% 6% Pain 12% 6% Fatigue 20% 10% Musculoskeletal and connective tissue disorders Back pain 15% 8% Arthralgia 9% 2% Bone pain 11% 6% Pain in extremity Percent difference (Filgrastim – Placebo) was 4%. 7% 3% Nervous system disorders Dizziness 14% 3% Respiratory, thoracic and mediastinal disorders Cough 14% 8% Dyspnea 13% 8% Skin and subcutaneous tissue disorders Rash 14% 5% Investigations Blood lactate dehydrogenase increased 6% 1% Blood alkaline phosphatase increased 6% 1% Adverse events with ≥ 5% higher incidence in filgrastim patients compared to placebo and associated with the sequelae of the underlying malignancy or cytotoxic chemotherapy delivered included anemia, constipation, diarrhea, oral pain, vomiting, asthenia, malaise, edema peripheral, hemoglobin decreased, decreased appetite, oropharyngeal pain, and alopecia. Adverse Reactions in Patients with Acute Myeloid Leukemia Adverse reaction data below are from a randomized, double-blind, placebo-controlled study in patients with AML (Study 4) who received an induction chemotherapy regimen of intravenous daunorubicin days 1, 2, and 3; cytosine arabinoside days 1 to 7; and etoposide days 1 to 5 and up to 3 additional courses of therapy (induction 2, and consolidation 1, 2) of intravenous daunorubicin, cytosine arabinoside, and etoposide. The safety population included 518 patients randomized to receive either 5 mcg/kg/day filgrastim (n = 257) or placebo (n = 261). The median age was 54 (range 16 to 89) years and 54% were male. Adverse reactions with ≥ 2% higher incidence in filgrastim patients compared to placebo included epistaxis, back pain, pain in extremity, erythema, and rash maculo-papular. Adverse events with ≥ 2% higher incidence in filgrastim patients compared to placebo and associated with the sequelae of the underlying malignancy or cytotoxic chemotherapy included diarrhea, constipation, and transfusion reaction. Adverse Reactions in Patients with Cancer Undergoing Bone Marrow Transplantation The following adverse reaction data are from one randomized, no treatment-controlled study in patients with acute lymphoblastic leukemia or lymphoblastic lymphoma receiving high-dose chemotherapy (cyclophosphamide or cytarabine, and melphalan) and total body irradiation (Study 5) and one randomized, no treatment-controlled study in patients with Hodgkin's disease (HD) and NHL undergoing high-dose chemotherapy and autologous bone marrow transplantation (Study 6). Patients receiving autologous bone marrow transplantation only were included in the analysis. A total of 100 patients received either 30 mcg/kg/day as a 4 hour infusion (Study 5) or 10 mcg/kg/day or 30 mcg/kg/day as a 24 hour infusion (Study 6) filgrastim (n = 72), no treatment control or placebo (n = 28). The median age was 30 (range 15 to 57) years, 57% were male. Adverse reactions with ≥ 5% higher incidence in filgrastim patients compared to patients receiving no filgrastim included rash and hypersensitivity. Adverse reactions in patients receiving intensive chemotherapy followed by autologous BMT with ≥ 5% higher incidence in filgrastim patients compared to patients receiving no filgrastim included thrombocytopenia, anemia, hypertension, sepsis, bronchitis, and insomnia. Adverse Reactions in Patients with Cancer Undergoing Autologous Peripheral Blood Progenitor Cell Collection The adverse reaction data in Table 3 are from a series of 7 trials in patients with cancer undergoing mobilization of autologous peripheral blood progenitor cells for collection by leukapheresis. Patients (n = 166) in all these trials underwent a similar mobilization/collection regimen: filgrastim was administered for 6 to 8 days‚ in most cases the apheresis procedure occurred on days 5‚ 6, and 7. The dosage of filgrastim ranged between 5 to 30 mcg/kg/day and was administered subcutaneously by injection or continuous infusion. The median age was 39 (range 15 to 67) years, and 48% were male. Table 3. Adverse Reactions in Patients with Cancer Undergoing Autologous PBPC in the Mobilization Phase (≥ 5% Incidence in Filgrastim Patients) System Organ Class Preferred Term Mobilization Phase (N = 166) Musculoskeletal and connective tissue disorders Bone pain 30% General disorders and administration site conditions Pyrexia 16% Investigations Blood alkaline phosphatase increased 11% Nervous system disorders Headache 10% Adverse Reactions in Patients with Severe Chronic Neutropenia The following adverse reaction data were identified in a randomized, controlled study in patients with SCN receiving filgrastim (Study 7). 123 patients were randomized to a 4 month observation period followed by subcutaneous filgrastim treatment or immediate subcutaneous filgrastim treatment. The median age was 12 years (range 7 months to 76 years) and 46% were male. The dosage of filgrastim was determined by the category of neutropenia. Initial dosage of filgrastim: • Idiopathic neutropenia: 3.6 mcg/kg/day • Cyclic neutropenia: 6 mcg/kg/day • Congenital neutropenia: 6 mcg/kg/day divided 2 times per day The dosage was increased incrementally to 12 mcg/kg/day divided 2 times per day if there was no response. Adverse reactions with ≥ 5% higher incidence in filgrastim patients compared to patients receiving no filgrastim included arthralgia, bone pain, back pain, muscle spasms, musculoskeletal pain, pain in extremity, splenomegaly, anemia, upper respiratory tract infection, and urinary tract infection (upper respiratory tract infection and urinary tract infection were higher in the filgrastim arm, total infection related events were lower in filgrastim-treated patients), epistaxis, chest pain, diarrhea, hypoesthesia, and alopecia. 6.2 Immunogenicity As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to filgrastim in the studies described below with the incidence of antibodies in other studies or to other products may be misleading. The incidence of antibody development in patients receiving filgrastim products has not been adequately determined. While available data suggest that a small proportion of patients developed binding antibodies to filgrastim products, the nature and specificity of these antibodies has not been adequately studied. In clinical studies using filgrastim, the incidence of antibodies binding to filgrastim was 3% (11/333). In these 11 patients, no evidence of a neutralizing response was observed using a cell-based bioassay. Cytopenias resulting from an antibody response to exogenous growth factors have been reported on rare occasions in patients treated with other recombinant growth factors. 6.3 Postmarketing Experience The following adverse reactions have been identified during post-approval use of filgrastim products. 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. • splenic rupture and splenomegaly (enlarged spleen) [see Warnings and Precautions (5.1) ] • acute respiratory distress syndrome [see Warnings and Precautions (5.2) ] • anaphylaxis [see Warnings and Precautions (5.3) ] • sickle cell disorders [see Warnings and Precautions (5.4) ] • glomerulonephritis [see Warnings and Precautions (5.5) ] • alveolar hemorrhage and hemoptysis [see Warnings and Precautions (5.6) ] • capillary leak syndrome [see Warnings and Precautions (5.7) ] • leukocytosis [see Warnings and Precautions (5.10) ] • cutaneous vasculitis [see Warnings and Precautions (5.11) ] • Sweet's syndrome (acute febrile neutrophilic dermatosis) • decreased bone density and osteoporosis in pediatric patients receiving chronic treatment with filgrastim products. • myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) in patients with breast and lung cancer receiving chemotherapy and/or radiotherapy [see Warnings and Precautions (5.8) ] • aortitis [see Warnings and Precautions (5.15) ]

4 CONTRAINDICATIONS NIVESTYM is contraindicated in patients with a history of serious allergic reactions to human granulocyte colony-stimulating factors such as filgrastim products or pegfilgrastim products [see Warnings and Precautions (5.3) ] . Patients with a history of serious allergic reactions to human granulocyte colony-stimulating factors such as filgrastim products or pegfilgrastim products. ( 4 )

11 DESCRIPTION Filgrastim-aafi is a 175 amino acid human granulocyte colony-stimulating factor (G-CSF) manufactured by recombinant DNA technology. NIVESTYM is produced by Escherichia coli ( E coli) bacteria into which has been inserted the human granulocyte colony-stimulating factor gene. NIVESTYM has a molecular weight of 18‚799 daltons. The protein has an amino acid sequence that is identical to the natural sequence predicted from human DNA sequence analysis‚ except for the addition of an N-terminal methionine necessary for expression in E coli . Because NIVESTYM is produced in E coli ‚ the product is non-glycosylated and thus differs from G-CSF isolated from a human cell. NIVESTYM is a sterile‚ clear‚ colorless‚ preservative-free liquid containing filgrastim-aafi injection for subcutaneous or intravenous use. The product is available in single-dose vials and prefilled syringes. The single-dose vials contain either 300 mcg/mL or 480 mcg/1.6 mL of filgrastim-aafi. The single-dose prefilled syringes contain either 300 mcg/0.5 mL or 480 mcg/0.8 mL of filgrastim-aafi. See Table 4 below for product composition of each single-dose vial or prefilled syringe.

2 DOSAGE AND ADMINISTRATION • Patients with cancer receiving myelosuppressive chemotherapy or induction and/or consolidation chemotherapy for AML. o Recommended starting dose is 5 mcg/kg/day subcutaneous injection, short intravenous infusion (15 to 30 minutes), or continuous intravenous infusion. See Full Prescribing Information for recommended dosage adjustments and timing of administration. ( 2.1 ) • Patients with cancer undergoing bone marrow transplantation. o 10 mcg/kg/day given as an intravenous infusion no longer than 24 hours. See Full Prescribing Information for recommended dosage adjustments and timing of administration. ( 2.2 ) • Patients undergoing autologous peripheral blood progenitor cell collection and therapy. o 10 mcg/kg/day subcutaneous injection. ( 2.3 ) o Administer for at least 4 days before first leukapheresis procedure and continue until last leukapheresis. ( 2.3 ) • Patients with congenital neutropenia. o Recommended starting dose is 6 mcg/kg subcutaneous injection twice daily. ( 2.4 ) • Patients with cyclic or idiopathic neutropenia. o Recommended starting dose is 5 mcg/kg subcutaneous injection daily. ( 2.4 ) • Direct administration of less than 0.3 mL (180 mcg) using NIVESTYM prefilled syringe is not recommended due to potential for dosing errors. ( 2.5 ) 2.1 Dosage in Patients with Cancer Receiving Myelosuppressive Chemotherapy or Induction and/or Consolidation Chemotherapy for AML The recommended starting dosage of NIVESTYM is 5 mcg/kg/day‚ administered as a single daily injection by subcutaneous injection‚ by short intravenous infusion (15 to 30 minutes)‚ or by continuous intravenous infusion. Obtain a complete blood count (CBC) and platelet count before instituting NIVESTYM therapy and monitor twice weekly during therapy. Consider dose escalation in increments of 5 mcg/kg for each chemotherapy cycle‚ according to the duration and severity of the absolute neutrophil count (ANC) nadir. Recommend stopping NIVESTYM if the ANC increases beyond 10‚000/mm 3 [see Warnings and Precautions (5.10) ] . Administer NIVESTYM at least 24 hours after cytotoxic chemotherapy. Do not administer NIVESTYM within the 24-hour period prior to chemotherapy [see Warnings and Precautions (5.13) ] . A transient increase in neutrophil count is typically seen 1 to 2 days after initiation of NIVESTYM therapy. Therefore, to ensure a sustained therapeutic response‚ administer NIVESTYM daily for up to 2 weeks or until the ANC has reached 10‚000/mm 3 following the expected chemotherapy-induced neutrophil nadir. The duration of NIVESTYM therapy needed to attenuate chemotherapy-induced neutropenia may be dependent on the myelosuppressive potential of the chemotherapy regimen employed. 2.2 Dosage in Patients with Cancer Undergoing Bone Marrow Transplantation The recommended dosage of NIVESTYM following bone marrow transplantation (BMT) is 10 mcg/kg/day given as an intravenous infusion no longer than 24 hours. Administer the first dose of NIVESTYM at least 24 hours after cytotoxic chemotherapy and at least 24 hours after bone marrow infusion. Monitor CBCs and platelet counts frequently following marrow transplantation. During the period of neutrophil recovery‚ titrate the daily dosage of NIVESTYM against the neutrophil response (see Table 1 ). Table 1. Recommended Dosage Adjustments During Neutrophil Recovery in Patients with Cancer Following BMT Absolute Neutrophil Count NIVESTYM Dosage Adjustment When ANC greater than 1000/mm 3 for 3 consecutive days Reduce to 5 mcg/kg/day If ANC decreases to less than 1000/mm 3 at any time during the 5 mcg/kg/day administration‚ increase NIVESTYM to 10 mcg/kg/day‚ and then follow the above steps. Then, if ANC remains greater than 1000/mm 3 for 3 more consecutive days Discontinue NIVESTYM Then, if ANC decreases to less than 1000/mm 3 Resume at 5 mcg/kg/day 2.3 Dosage in Patients Undergoing Autologous Peripheral Blood Progenitor Cell Collection and Therapy The recommended dosage of NIVESTYM for the mobilization of autologous peripheral blood progenitor cells (PBPC) is 10 mcg/kg/day given by subcutaneous injection. Administer NIVESTYM for at least 4 days before the first leukapheresis procedure and continue until the last leukapheresis. Although the optimal duration of NIVESTYM administration and leukapheresis schedule have not been established‚ administration of filgrastim for 6 to 7 days with leukaphereses on days 5‚ 6‚ and 7 was found to be safe and effective [see Clinical Studies (14.4) ] . Monitor neutrophil counts after 4 days of NIVESTYM‚ and discontinue NIVESTYM if the white blood cell (WBC) count rises to greater than 100‚000/mm 3 . 2.4 Dosage in Patients with Severe Chronic Neutropenia Prior to starting NIVESTYM in patients with suspected chronic neutropenia, confirm the diagnosis of severe chronic neutropenia (SCN) by evaluating serial CBCs with differential and platelet counts‚ and evaluating bone marrow morphology and karyotype. The use of NIVESTYM prior to confirmation of a correct diagnosis of SCN may impair diagnostic efforts and may thus impair or delay evaluation and treatment of an underlying condition‚ other than SCN‚ causing the neutropenia. The recommended starting dosage in patients with Congenital Neutropenia is 6 mcg/kg as a twice daily subcutaneous injection and the recommended starting dosage in patients with Idiopathic or Cyclic Neutropenia is 5 mcg/kg as a single daily subcutaneous injection. Dosage Adjustments in Patients with Severe Chronic Neutropenia Chronic daily administration is required to maintain clinical benefit. Individualize the dosage based on the patient's clinical course as well as ANC. In the SCN postmarketing surveillance study, the reported median daily doses of filgrastim were: 6 mcg/kg (congenital neutropenia), 2.1 mcg/kg (cyclic neutropenia), and 1.2 mcg/kg (idiopathic neutropenia). In rare instances, patients with congenital neutropenia have required doses of filgrastim greater than or equal to 100 mcg/kg/day. Monitor CBCs for Dosage Adjustments During the initial 4 weeks of NIVESTYM therapy and during the 2 weeks following any dosage adjustment‚ monitor CBCs with differential and platelet counts. Once a patient is clinically stable‚ monitor CBCs with differential and platelet counts monthly during the first year of treatment. Thereafter, if the patient is clinically stable, less frequent routine monitoring is recommended. 2.5 Important Administration Instructions Patient self-administration and administration by a caregiver may benefit from training by a healthcare professional. Training should aim to demonstrate to those patients and caregivers how to measure the dose using the prefilled syringe, and the focus should be on ensuring that a patient or caregiver can successfully perform all of the steps in the Instructions for Use of NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard. If a patient or caregiver is not able to demonstrate that they can measure the dose and administer the product successfully, you should consider whether the patient is an appropriate candidate for self-administration of NIVESTYM [see Instructions for Use ] . NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard is not designed to allow for direct administration of doses of less than 0.3 mL (180 mcg). The spring-mechanism of the needle guard apparatus affixed to the prefilled syringe interferes with the visibility of the graduation markings on the syringe barrel corresponding to 0.1 mL and 0.2 mL. The visibility of these markings is necessary to accurately measure doses of NIVESTYM less than 0.3 mL (180 mcg) for direct administration. Thus, the direct administration to patients requiring doses of less than 0.3 mL (180 mcg) is not recommended due to the potential for dosing errors. For direct administration of doses less than 0.3 mL (180 mcg) use NIVESTYM single-dose vial. NIVESTYM is supplied in single-dose vials (for subcutaneous use or intravenous infusion) and single-dose prefilled syringes (for subcutaneous use) [see Dosage Forms and Strengths (3) ] . Prior to use‚ remove the vial or prefilled syringe from the refrigerator and allow NIVESTYM to reach room temperature for a minimum of 30 minutes and a maximum of 24 hours. Discard any vial or prefilled syringe left at room temperature for greater than 24 hours. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit (the solution is clear and colorless). Do not administer NIVESTYM if particulates or discoloration are observed. Discard unused portion of NIVESTYM in vials or prefilled syringes; do not re-enter the vial. Do not save unused drug for later administration. Subcutaneous Injection Inject NIVESTYM subcutaneously in the outer area of upper arms, abdomen, thighs, or upper outer areas of the buttock. If patients or caregivers are to administer NIVESTYM, instruct them in appropriate injection technique and ask them to follow the subcutaneous injection procedures in the Instructions for Use for the vial or prefilled syringe [see Patient Counseling Information (17) ] . Training by the healthcare provider should aim to demonstrate to those patients and caregivers how to measure the dose of NIVESTYM, and the focus should be on ensuring that a patient or caregiver can successfully perform all of the steps in the Instructions for Use for the vial or prefilled syringe. If a patient or caregiver is not able to demonstrate that they can measure the dose and administer the product successfully, you should consider whether the patient is an appropriate candidate for self-administration of NIVESTYM or whether the patient would benefit from a different NIVESTYM presentation. If a patient or caregiver experiences difficulty measuring the required dose, especially if it is other than the entire contents of the NIVESTYM prefilled syringe, use of the NIVESTYM vial may be considered. If the patient or caregiver misses a dose of NIVESTYM, instruct them to contact their healthcare provider. Administration Instructions for the Prefilled Syringe The NIVESTYM syringe plunger stopper and needle cover are not made with natural rubber latex. Administration Instructions for Dilution (Vial Only) If required for intravenous administration‚ NIVESTYM (vial only) may be diluted in 5% Dextrose Injection, USP from a concentration of 300 mcg/mL to 5 mcg/mL (do not dilute to a final concentration less than 5 mcg/mL). NIVESTYM diluted to concentrations from 5 mcg/mL to 15 mcg/mL should be protected from adsorption to plastic materials by the addition of Albumin (Human) to a final concentration of 2 mg/mL. When diluted in 5% Dextrose Injection, USP or 5% Dextrose plus Albumin (Human)‚ NIVESTYM is compatible with glass bottles‚ polyvinyl chloride (PVC) and polyolefin intravenous bags‚ and polypropylene syringes. Do not dilute with saline at any time because the product may precipitate. Diluted NIVESTYM solution can be stored at room temperature for up to 24 hours. This 24 hour time period includes the time during room temperature storage of the infusion solution and the duration of the infusion.

1 INDICATIONS AND USAGE NIVESTYM is a leukocyte growth factor indicated to • Decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a significant incidence of severe neutropenia with fever. ( 1.1 ) • Reduce the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML). ( 1.2 ) • Reduce the duration of neutropenia and neutropenia-related clinical sequelae‚ e.g.‚ febrile neutropenia, in patients with nonmyeloid malignancies undergoing myeloablative chemotherapy followed by bone marrow transplantation (BMT). ( 1.3 ) • Mobilize autologous hematopoietic progenitor cells into the peripheral blood for collection by leukapheresis. ( 1.4 ) • Reduce the incidence and duration of sequelae of severe neutropenia (e.g.‚ fever‚ infections‚ oropharyngeal ulcers) in symptomatic patients with congenital neutropenia‚ cyclic neutropenia‚ or idiopathic neutropenia. ( 1.5 ) 1.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy NIVESTYM is indicated to decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a significant incidence of severe neutropenia with fever [see Clinical Studies (14.1) ] . 1.2 Patients with Acute Myeloid Leukemia Receiving Induction or Consolidation Chemotherapy NIVESTYM is indicated for reducing the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML) [see Clinical Studies (14.2) ] . 1.3 Patients with Cancer Undergoing Bone Marrow Transplantation NIVESTYM is indicated to reduce the duration of neutropenia and neutropenia-related clinical sequelae‚ e.g.‚ febrile neutropenia, in patients with nonmyeloid malignancies undergoing myeloablative chemotherapy followed by bone marrow transplantation [see Clinical Studies (14.3) ]. 1.4 Patients Undergoing Autologous Peripheral Blood Progenitor Cell Collection and Therapy NIVESTYM is indicated for the mobilization of autologous hematopoietic progenitor cells into the peripheral blood for collection by leukapheresis [see Clinical Studies (14.4) ] . 1.5 Patients with Severe Chronic Neutropenia NIVESTYM is indicated for chronic administration to reduce the incidence and duration of sequelae of neutropenia (e.g.‚ fever‚ infections‚ oropharyngeal ulcers) in symptomatic patients with congenital neutropenia‚ cyclic neutropenia‚ or idiopathic neutropenia [see Clinical Studies (14.5) ] .

10 OVERDOSAGE The maximum tolerated dose of filgrastim products has not been determined. In filgrastim clinical trials of patients with cancer receiving myelosuppressive chemotherapy‚ WBC counts > 100‚000/mm 3 have been reported in less than 5% of patients‚ but were not associated with any reported adverse clinical effects. Patients in the BMT studies received up to 138 mcg/kg/day without toxic effects‚ although there was a flattening of the dose response curve above daily doses of greater than 10 mcg/kg/day.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Colony-stimulating factors are glycoproteins which act on hematopoietic cells by binding to specific cell surface receptors and stimulating proliferation‚ differentiation commitment‚ and some end-cell functional activation. Endogenous G-CSF is a lineage-specific colony-stimulating factor that is produced by monocytes‚ fibroblasts, and endothelial cells. G-CSF regulates the production of neutrophils within the bone marrow and affects neutrophil progenitor proliferation‚ differentiation, and selected end-cell functions (including enhanced phagocytic ability‚ priming of the cellular metabolism associated with respiratory burst‚ antibody-dependent killing, and the increased expression of some cell surface antigens). G-CSF is not species-specific and has been shown to have minimal direct in vivo or in vitro effects on the production or activity of hematopoietic cell types other than the neutrophil lineage. 12.2 Pharmacodynamics In phase 1 studies involving 96 patients with various non-myeloid malignancies‚ filgrastim administration resulted in a dose-dependent increase in circulating neutrophil counts over the dose range of 1 to 70 mcg/kg/day. This increase in neutrophil counts was observed whether filgrastim was administered intravenous (1 to 70 mcg/kg twice daily)‚ subcutaneous (1 to 3 mcg/kg once daily)‚ or by continuous subcutaneous infusion (3 to 11 mcg/kg/day). With discontinuation of filgrastim therapy‚ neutrophil counts returned to baseline in most cases within 4 days. Isolated neutrophils displayed normal phagocytic (measured by zymosan-stimulated chemoluminescence) and chemotactic (measured by migration under agarose using N-formyl-methionyl-leucyl-phenylalanine [fMLP] as the chemotaxin) activity in vitro. The absolute monocyte count was reported to increase in a dose-dependent manner in most patients receiving filgrastim; however‚ the percentage of monocytes in the differential count remained within the normal range. Absolute counts of both eosinophils and basophils did not change and were within the normal range following administration of filgrastim. Increases in lymphocyte counts following filgrastim administration have been reported in some normal subjects and patients with cancer. White blood cell (WBC) differentials obtained during clinical trials have demonstrated a shift towards earlier granulocyte progenitor cells (left shift)‚ including the appearance of promyelocytes and myeloblasts‚ usually during neutrophil recovery following the chemotherapy-induced nadir. In addition‚ Dohle bodies‚ increased granulocyte granulation‚ and hypersegmented neutrophils have been observed. Such changes were transient and were not associated with clinical sequelae, nor were they necessarily associated with infection. 12.3 Pharmacokinetics Filgrastim products exhibit nonlinear pharmacokinetics. Clearance is dependent on filgrastim product concentration and neutrophil count: G-CSF receptor-mediated clearance is saturated by high concentration of filgrastim products and is diminished by neutropenia. In addition, filgrastim products are cleared by the kidney. Subcutaneous administration of 3.45 mcg/kg and 11.5 mcg/kg of filgrastim resulted in maximum serum concentrations of 4 and 49 ng/mL‚ respectively‚ within 2 to 8 hours. After intravenous administration, the volume of distribution averaged 150 mL/kg and the elimination half-life was approximately 3.5 hours in both normal subjects and cancer subjects. Clearance rates of filgrastim were approximately 0.5 to 0.7 mL/minute/kg. Single parenteral doses or daily intravenous doses‚ over a 14-day period‚ resulted in comparable half-lives. The half-lives were similar for intravenous administration (231 minutes‚ following doses of 34.5 mcg/kg) and for subcutaneous administration (210 minutes‚ following filgrastim dosages of 3.45 mcg/kg). Continuous 24-hour intravenous infusions of 20 mcg/kg over an 11 to 20-day period produced steady-state serum concentrations of filgrastim with no evidence of drug accumulation over the time period investigated. The absolute bioavailability of filgrastim after subcutaneous administration is 60% to 70%. Specific Populations Pediatric Patients The pharmacokinetics of filgrastim in pediatric patients after chemotherapy are similar to those in adult patients receiving the same weight-normalized doses, suggesting no age-related differences in the pharmacokinetics of filgrastim [see Use in Specific Populations (8.4) ] . Renal Impairment In a study with healthy volunteers, subjects with moderate renal impairment, and subjects with end-stage renal disease (n = 4 per group), higher serum concentrations were observed in subjects with end-stage renal disease. However, dose adjustment in patients with renal impairment is not necessary. Hepatic Impairment Pharmacokinetics and pharmacodynamics of filgrastim are similar between subjects with hepatic impairment and healthy subjects (n = 12/group). The study included 10 subjects with mild hepatic impairment (Child-Pugh Class A) and 2 subjects with moderate hepatic impairment (Child-Pugh Class B). Therefore, NIVESTYM dose adjustment for patients with hepatic impairment is not necessary.

12.2 Pharmacodynamics In phase 1 studies involving 96 patients with various non-myeloid malignancies‚ filgrastim administration resulted in a dose-dependent increase in circulating neutrophil counts over the dose range of 1 to 70 mcg/kg/day. This increase in neutrophil counts was observed whether filgrastim was administered intravenous (1 to 70 mcg/kg twice daily)‚ subcutaneous (1 to 3 mcg/kg once daily)‚ or by continuous subcutaneous infusion (3 to 11 mcg/kg/day). With discontinuation of filgrastim therapy‚ neutrophil counts returned to baseline in most cases within 4 days. Isolated neutrophils displayed normal phagocytic (measured by zymosan-stimulated chemoluminescence) and chemotactic (measured by migration under agarose using N-formyl-methionyl-leucyl-phenylalanine [fMLP] as the chemotaxin) activity in vitro. The absolute monocyte count was reported to increase in a dose-dependent manner in most patients receiving filgrastim; however‚ the percentage of monocytes in the differential count remained within the normal range. Absolute counts of both eosinophils and basophils did not change and were within the normal range following administration of filgrastim. Increases in lymphocyte counts following filgrastim administration have been reported in some normal subjects and patients with cancer. White blood cell (WBC) differentials obtained during clinical trials have demonstrated a shift towards earlier granulocyte progenitor cells (left shift)‚ including the appearance of promyelocytes and myeloblasts‚ usually during neutrophil recovery following the chemotherapy-induced nadir. In addition‚ Dohle bodies‚ increased granulocyte granulation‚ and hypersegmented neutrophils have been observed. Such changes were transient and were not associated with clinical sequelae, nor were they necessarily associated with infection.

12.3 Pharmacokinetics Filgrastim products exhibit nonlinear pharmacokinetics. Clearance is dependent on filgrastim product concentration and neutrophil count: G-CSF receptor-mediated clearance is saturated by high concentration of filgrastim products and is diminished by neutropenia. In addition, filgrastim products are cleared by the kidney. Subcutaneous administration of 3.45 mcg/kg and 11.5 mcg/kg of filgrastim resulted in maximum serum concentrations of 4 and 49 ng/mL‚ respectively‚ within 2 to 8 hours. After intravenous administration, the volume of distribution averaged 150 mL/kg and the elimination half-life was approximately 3.5 hours in both normal subjects and cancer subjects. Clearance rates of filgrastim were approximately 0.5 to 0.7 mL/minute/kg. Single parenteral doses or daily intravenous doses‚ over a 14-day period‚ resulted in comparable half-lives. The half-lives were similar for intravenous administration (231 minutes‚ following doses of 34.5 mcg/kg) and for subcutaneous administration (210 minutes‚ following filgrastim dosages of 3.45 mcg/kg). Continuous 24-hour intravenous infusions of 20 mcg/kg over an 11 to 20-day period produced steady-state serum concentrations of filgrastim with no evidence of drug accumulation over the time period investigated. The absolute bioavailability of filgrastim after subcutaneous administration is 60% to 70%. Specific Populations Pediatric Patients The pharmacokinetics of filgrastim in pediatric patients after chemotherapy are similar to those in adult patients receiving the same weight-normalized doses, suggesting no age-related differences in the pharmacokinetics of filgrastim [see Use in Specific Populations (8.4) ] . Renal Impairment In a study with healthy volunteers, subjects with moderate renal impairment, and subjects with end-stage renal disease (n = 4 per group), higher serum concentrations were observed in subjects with end-stage renal disease. However, dose adjustment in patients with renal impairment is not necessary. Hepatic Impairment Pharmacokinetics and pharmacodynamics of filgrastim are similar between subjects with hepatic impairment and healthy subjects (n = 12/group). The study included 10 subjects with mild hepatic impairment (Child-Pugh Class A) and 2 subjects with moderate hepatic impairment (Child-Pugh Class B). Therefore, NIVESTYM dose adjustment for patients with hepatic impairment is not necessary.

13.2 Animal Toxicology and Pharmacology Filgrastim was administered to monkeys‚ dogs‚ hamsters‚ rats‚ and mice as part of a nonclinical toxicology program, which included studies up to 1 year duration. In the repeated-dose studies‚ changes observed were attributable to the expected pharmacological actions of filgrastim (i.e.‚ dose-dependent increases in white blood cell counts‚ increased circulating segmented neutrophils‚ and increased myeloid:erythroid ratio in bone marrow). Histopathologic examination of the liver and spleen revealed evidence of ongoing extramedullary granulopoiesis, and dose-related increases in spleen weight were seen in all species. These changes all reversed after discontinuation of treatment.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility The carcinogenic potential of filgrastim products has not been studied. Filgrastim failed to induce bacterial gene mutations in either the presence or absence of a drug metabolizing enzyme system. Filgrastim had no observed effect on the fertility of male or female rats at doses up to 500 mcg/kg.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Review the steps for direct patient administration with patients and caregivers. Training by the healthcare provider should aim to ensure that patients and caregivers can successfully perform all of the steps in the Instructions for Use of NIVESTYM vial and prefilled syringe, including showing the patient or caregiver how to measure the required dose, particularly if a patient is on a dose other than the entire prefilled syringe. If a patient or caregiver is not able to demonstrate that they can measure the dose and administer the product successfully, you should consider whether the patient is an appropriate candidate for self-administration of NIVESTYM or whether the patient would benefit from a different NIVESTYM presentation. Advise patients of the following risks and potential risks with NIVESTYM: • Rupture or enlargement of the spleen may occur. Symptoms include left upper quadrant abdominal pain or left shoulder pain. Advise patients to report pain in these areas to their physician immediately [see Warnings and Precautions (5.1) ] . • Dyspnea, with or without fever, progressing to Acute Respiratory Distress Syndrome, may occur. Advise patients to report dyspnea to their physician immediately [see Warnings and Precautions (5.2) ] . • Serious allergic reactions may occur, which may be signaled by rash‚ facial edema‚ wheezing‚ dyspnea‚ hypotension‚ or tachycardia. Advise patients to seek immediate medical attention if signs or symptoms of hypersensitivity reaction occur [see Warnings and Precautions (5.3) ] . • In patients with sickle cell disease, sickle cell crisis and death have occurred. Discuss potential risks and benefits for patients with sickle cell disease prior to the administration of human granulocyte colony-stimulating factors [see Warnings and Precautions (5.4) ] . • Glomerulonephritis may occur. Symptoms include swelling of the face or ankles, dark colored urine or blood in the urine, or a decrease in urine production. Advise patients to report signs or symptoms of glomerulonephritis to their physician immediately [see Warnings and Precautions (5.5) ] . • There may be an increased risk of Myelodysplastic Syndrome and/or Acute Myeloid Leukemia in patients with congenital neutropenia who receive filgrastim products and in patients with breast and lung cancer who receive filgrastim products in conjunction with chemotherapy and/or radiation therapy. Symptoms of MDS and AML may include tiredness, fever, and easy bruising or bleeding. Advise patients to report to their physician signs and symptoms of MDS/AML [see Warnings and Precautions (5.8) ] . • Cutaneous vasculitis may occur, which may be signaled by purpura or erythema. Advise patients to report signs or symptoms of vasculitis to their physician immediately [see Warnings and Precautions (5.11) ] . • Aortitis may occur. Symptoms may include fever, abdominal pain, malaise, back pain, and increased inflammatory markers. Advise patients to report signs and symptoms of aortitis to their physician immediately [see Warnings and Precautions (5.15) ] . Instruct patients who self-administer NIVESTYM using the prefilled syringe or single-dose vial of the: • Importance of following the applicable Instructions for Use. • Dangers of reusing needles, syringes, or unused portions of single-dose vials. • Importance of following local requirements for proper disposal of used syringes, needles, and unused vials. • Importance of informing the healthcare provider if difficulty occurs when measuring or administering partial contents of the NIVESTYM prefilled syringe. If difficulty occurs, use of the NIVESTYM vial may be considered. • Difference in product concentration of the NIVESTYM prefilled syringe in comparison to the NIVESTYM vial. When switching patients from the NIVESTYM prefilled syringe to the NIVESTYM vial, or vice versa, ensure that patients understand the correct volume to be administered since the concentration of NIVESTYM differs between the prefilled syringe and the vial.

Using your prefilled syringe • It is important that you do not try to give the injection unless you or your caregiver has received training from your healthcare provider. • You should not inject a dose of NIVESTYM less than 0.3 mL (180 mcg) from a NIVESTYM prefilled syringe. A dose less than 0.3 mL cannot be accurately measured using the NIVESTYM prefilled syringe. • Make sure the name NIVESTYM appears on the carton and prefilled syringe label. • Do not use a NIVESTYM prefilled syringe after the expiration date on the label. • Do not shake the NIVESTYM prefilled syringe. • The prefilled syringe has a needle guard that needs to be activated to cover the needle after the injection is given. The needle guard will help prevent needle stick injuries to anyone who handles the prefilled syringe. • Do not remove the needle cover from the prefilled syringe until you are ready to inject. • Do not use the NIVESTYM prefilled syringe if the needle cover is missing. • Do not use the prefilled syringe if the carton is open or damaged . • Do not use a prefilled syringe if it has been dropped on a hard surface. The prefilled syringe may be broken even if you cannot see the break. Use a new prefilled syringe. Call your healthcare provider if you have any questions. About the NIVESTYM prefilled syringe • NIVESTYM prefilled syringes come in two strengths. Depending on your prescription, you will receive NIVESTYM prefilled syringes that contain 300 mcg/0.5mL or 480 mcg/0.8mL of medicine. Your healthcare provider will determine the dose in milliliters (mL) that you will need to give based on your body weight. • When you receive your NIVESTYM prefilled syringes, always check to see that the: o name NIVESTYM appears on the carton and prefilled syringe label. o expiration date on the prefilled syringe label has not passed. You should not use a prefilled syringe after the date on the label. o strength of NIVESTYM (number of micrograms on the carton containing the prefilled syringe) is the same as what your healthcare provider prescribed. NIVESTYM prefilled syringe parts (see Figure A ). NIVESTYM 300 mcg/0.5mL prefilled syringe is shown as an example. Figure A What you need for your injection Included in the carton: • 1 new NIVESTYM prefilled syringe Not included in the carton (see Figure B ) • 1 adhesive bandage • 1 alcohol wipe • 1 cotton ball or gauze • sharps disposal container Figure B Figure C shows a needle guard that has not yet been activated. The prefilled syringe is ready for use. This is what the prefilled syringe looks like before use. Figure C Figure D shows a needle guard that has been activated. This is what the prefilled syringe looks like after use. Figure D Preparing the NIVESTYM prefilled syringe Step 1: Find a clean, well-lit flat work surface. Step 2: Take the carton containing the NIVESTYM prefilled syringe out of the refrigerator and leave it unopened on your work surface for at least 30 minutes so that it reaches room temperature. Put the original carton with any unused prefilled syringes back in the refrigerator. • Do not shake the prefilled syringe. • Do not leave the prefilled syringe in direct sunlight. Step 3: Wash your hands with soap and water. Step 4: Remove the prefilled syringe from the carton. Check to make sure that the needle guard is covering the barrel of the prefilled syringe. Do not push the needle guard over the needle cover before the injection. This may activate or lock the needle guard. See Figure C above that shows how the prefilled syringe looks before use. If the needle guard is covering the needle that means it has been activated. See Figure D above that shows how the prefilled syringe looks after use. Do not use the NIVESTYM prefilled syringe. Get another prefilled syringe that has not been activated and is ready to use. Step 5: Check the expiration date on the NIVESTYM prefilled syringe. Do not use the NIVESTYM prefilled syringe if the expiration date has passed. Step 6: Inspect the medicine and prefilled syringe. Turn the prefilled syringe so you can see the medicine and markings in the window. Look through the window on the NIVESTYM prefilled syringe. Make sure the medicine in the prefilled syringe is clear and colorless. • Do not use the NIVESTYM prefilled syringe if: o The medicine is cloudy or discolored or contains flakes or particles. o Any part of the prefilled syringe appears cracked or broken. o The prefilled syringe has been dropped. o The needle cover is missing or not securely attached. o The expiration date printed on the label has passed. • In all cases, use a new prefilled syringe and call your healthcare provider. Step 7: Choose the injection site • When giving your injections, follow your healthcare provider's instructions about changing the site for each injection. • Areas of your body that you may use as injection sites include (See Figure E ): o front of your thigh o stomach area (abdomen), except for a 2-inch area around your navel (belly button) o outer upper outer arms, only if a caregiver is giving you the injection o upper outer area of your buttocks, only if a caregiver is giving you the injection o Figure E o Choose a different site for each injection of NIVESTYM. o Do not inject into areas where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks. Step 8: Clean your injection site with an alcohol wipe. See Figure F . • Let your skin dry. • Do not touch this area again before injecting. • Figure F Step 9: Hold the prefilled syringe by the needle guard with the needle cover pointing up. Carefully pull the needle cover straight off and away from your body. Throw away the needle cover. Do not recap the needle. See Figure G . Figure G Your healthcare provider has prescribed either a "full" syringe dose or a "partial" syringe dose. • If you are prescribed a partial dose of NIVESTYM, follow Steps 10 through 18. • If you are prescribed a full dose, you will inject all of the medicine from your prefilled syringe. For a full dose, skip Steps 10 and 11, and follow Steps 12 through 18. Partial dosing Step 10: Point the needle up and tap gently until the air rises to the top. See Figure H . Figure H Figure H Step 11: Holding the prefilled syringe as shown, slowly push up on the plunger rod to push out the extra air and medicine until the end of the conical base (edge) of the plunger stopper lines up with the syringe marking for your prescribed dose. See Figure I for an example of a dose of 0.3 mL. Your dose may be different than the example shown. Be careful not to activate the needle guard before use. Do not use a NIVESTYM prefilled syringe that has been activated. Check again to make sure the correct dose of NIVESTYM is in the prefilled syringe.

14 CLINICAL STUDIES 14.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy The safety and efficacy of filgrastim to decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs were established in a randomized‚ double-blind‚ placebo-controlled trial conducted in patients with small cell lung cancer (Study 1). In Study 1, patients received up to 6 cycles of intravenous chemotherapy including intravenous cyclophosphamide and doxorubicin on day 1; and etoposide on days 1, 2, and 3 of 21 day cycles. Patients were randomized to receive filgrastim (n = 99) at a dose of 230 mcg/m 2 (4 to 8 mcg/kg/day) or placebo (n = 111). Study drug was administered subcutaneously daily beginning on day 4, for a maximum of 14 days. A total of 210 patients were evaluable for efficacy and 207 were evaluable for safety. The demographic and disease characteristics were balanced between arms with a median age of 62 (range 31 to 80) years; 64% males; 89% Caucasian; 72% extensive disease and 28% limited disease. The main efficacy endpoint was the incidence of febrile neutropenia. Febrile neutropenia was defined as an ANC < 1000/mm 3 and temperature > 38.2°C. Treatment with filgrastim resulted in a clinically and statistically significant reduction in the incidence of infection‚ as manifested by febrile neutropenia, 40% for filgrastim -treated patients and 76% for placebo-treated patients (p < 0.001). There were also statistically significant reductions in the incidence and overall duration of infection manifested by febrile neutropenia; the incidence, severity and duration of severe neutropenia (ANC < 500/mm 3 ); the incidence and overall duration of hospital admissions; and the number of reported days of antibiotic use. 14.2 Patients with Acute Myeloid Leukemia Receiving Induction or Consolidation Chemotherapy The safety and efficacy of filgrastim to reduce the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML) was established in a randomized, double-blind‚ placebo-controlled‚ multi-center trial in patients with newly diagnosed, de novo AML (Study 4). In Study 4 the initial induction therapy consisted of intravenous daunorubicin days 1, 2, and 3; cytosine arabinoside days 1 to 7; and etoposide days 1 to 5. Patients were randomized to receive subcutaneous filgrastim (n = 259) at a dose of 5 mcg/kg/day or placebo (n = 262) from 24 hours after the last dose of chemotherapy until neutrophil recovery (ANC ≥ 1000/mm 3 for 3 consecutive days or ≥ 10,000/mm 3 for 1 day) or for a maximum of 35 days. The demographic and disease characteristics were balanced between arms with a median age of 54 (range 16 to 89) years; 54% males; initial white blood cell count (65% < 25,000/mm 3 and 27% > 100,000/mm 3 ); 29% unfavorable cytogenetics. The main efficacy endpoint was median duration of severe neutropenia defined as neutrophil count < 500/mm 3 . Treatment with filgrastim resulted in a clinically and statistically significant reduction in median number of days of severe neutropenia, filgrastim -treated patients 14 days, placebo-treated patients 19 days (p = 0.0001: difference of 5 days (95% CI: -6.0, -4.0)). There was a reduction in the median duration of intravenous antibiotic use, filgrastim -treated patients: 15 days versus placebo-treated patients: 18.5 days; a reduction in the median duration of hospitalization, filgrastim-treated patients: 20 days versus placebo-treated patients: 25 days. There were no statistically significant differences between the filgrastim and the placebo groups in complete remission rate (69% - filgrastim, 68% - placebo), median time to progression of all randomized patients (165 days - filgrastim, 186 days - placebo), or median overall survival (380 days - filgrastim, 425 days - placebo). 14.3 Patients with Cancer Undergoing Bone Marrow Transplantation The safety and efficacy of filgrastim to reduce the duration of neutropenia in patients with nonmyeloid malignancies undergoing myeloablative chemotherapy followed by autologous bone marrow transplantation was evaluated in 2 randomized controlled trials of patients with lymphoma (Study 6 and Study 9). The safety and efficacy of filgrastim to reduce the duration of neutropenia in patients undergoing myeloablative chemotherapy followed by allogeneic bone marrow transplantation was evaluated in a randomized placebo controlled trial (Study 10). In Study 6 patients with Hodgkin's disease received a preparative regimen of intravenous cyclophosphamide, etoposide, and BCNU ("CVP"), and patients with non-Hodgkin's lymphoma received intravenous BCNU, etoposide, cytosine arabinoside and melphalan ("BEAM"). There were 54 patients randomized 1:1:1 to control, filgrastim 10 mcg/kg/day, and filgrastim 30 mcg/kg/day as a 24 hour continuous infusion starting 24 hours after bone marrow infusion for a maximum of 28 days. The median age was 33 (range 17 to 57) years; 56% males; 69% Hodgkin's disease and 31% non-Hodgkin's lymphoma. The main efficacy endpoint was duration of severe neutropenia ANC < 500/mm 3 . A statistically significant reduction in the median number of days of severe neutropenia (ANC < 500/mm 3 ) occurred in the filgrastim -treated groups versus the control group (23 days in the control group‚ 11 days in the 10 mcg/kg/day group, and 14 days in the 30 mcg/kg/day group [11 days in the combined treatment groups‚ p = 0.004]). In Study 9, patients with Hodgkin's disease and non-Hodgkin's lymphoma received a preparative regimen of intravenous cyclophosphamide, etoposide, and BCNU ("CVP"). There were 43 evaluable patients randomized to continuous subcutaneous infusion filgrastim 10 mcg/kg/day (n = 19), filgrastim 30 mcg/kg/day (n = 10) and no treatment (n = 14) starting the day after marrow infusion for a maximum of 28 days. The median age was 33 (range 17 to 56) years; 67% males; 28% Hodgkin's disease and 72% non-Hodgkin's lymphoma. The main efficacy endpoint was duration of severe neutropenia. There was statistically significant reduction in the median number of days of severe neutropenia (ANC < 500/mm 3 ) in the filgrastim-treated groups versus the control group (21.5 days in the control group versus 10 days in the filgrastim -treated groups, p < 0.001). The number of days of febrile neutropenia was also reduced significantly in this study (13.5 days in the control group versus 5 days in the filgrastim--treated groups‚ p < 0.0001). In Study 10, 70 patients scheduled to undergo bone marrow transplantation for multiple underlying conditions using multiple preparative regimens were randomized to receive filgrastim 300 mcg/m 2 /day (n = 33) or placebo (n = 37) days 5 through 28 after marrow infusion. The median age was 18 (range 1 to 45) years, 56% males. The underlying disease was: 67% hematologic malignancy, 24% aplastic anemia, 9% other. A statistically significant reduction in the median number of days of severe neutropenia occurred in the treated group versus the control group (19 days in the control group and 15 days in the treatment group‚ p < 0.001) and time to recovery of ANC to ≥ 500/mm 3 (21 days in the control group and 16 days in the treatment group‚ p < 0.001). 14.4 Patients Undergoing Autologous Peripheral Blood Progenitor Cell Collection and Therapy The safety and efficacy of filgrastim to mobilize autologous peripheral blood progenitor cells for collection by leukapheresis was supported by the experience in uncontrolled trials, and a randomized trial comparing hematopoietic stem cell rescue using filgrastim mobilized autologous peripheral blood progenitor cells to autologous bone marrow (Study 11). Patients in all these trials underwent a similar mobilization/collection regimen: filgrastim was administered for 6 to 7 days‚ in most cases the apheresis procedure occurred on days 5‚ 6, and 7. The dose of filgrastim ranged between 10 to 24 mcg/kg/day and was administered subcutaneously by injection or continuous intravenous infusion. Engraftment was evaluated in 64 patients who underwent transplantation using filgrastim mobilized autologous hematopoietic progenitor cells in uncontrolled trials. Two of the 64 patients (3%) did not achieve the criteria for engraftment as defined by a platelet count ≥ 20‚000/mm 3 by day 28. In clinical trials of filgrastim for the mobilization of hematopoietic progenitor cells‚ filgrastim was administered to patients at doses between 5 to 24 mcg/kg/day after reinfusion of the collected cells until a sustainable ANC (≥ 500/mm 3 ) was reached. The rate of engraftment of these cells in the absence of filgrastim post transplantation has not been studied. Study 11 was a randomized, unblinded study of patients with Hodgkin's disease or non-Hodgkin's lymphoma undergoing myeloablative chemotherapy‚ 27 patients received filgrastim-mobilized autologous hematopoietic progenitor cells and 31 patients received autologous bone marrow. The preparative regimen was intravenous BCNU, etoposide, cytosine arabinoside and melphalan ("BEAM"). Patients received daily filgrastim 24 hours after stem cell infusion at a dose of 5 mcg/kg/day. The median age was 33 (range 1 to 59) years; 64% males; 57% Hodgkin's disease and 43% non-Hodgkin's lymphoma. The main efficacy endpoint was number of days of platelet transfusions. Patients randomized to filgrastim-mobilized autologous peripheral blood progenitor cells compared to autologous bone marrow had significantly fewer days of platelet transfusions (median 6 vs 10 days). 14.5 Patients with Severe Chronic Neutropenia The safety and efficacy of filgrastim to reduce the incidence and duration of sequelae of neutropenia (that is fever‚ infections, oropharyngeal ulcers) in symptomatic adult and pediatric patients with congenital neutropenia‚ cyclic neutropenia‚ or idiopathic neutropenia was established in a randomized controlled trial conducted in patients with severe neutropenia (Study 7). Patients eligible for Study 7 had a history of severe chronic neutropenia documented with an ANC < 500/mm 3 on three occasions during a 6 month period, or in patients with cyclic neutropenia 5 consecutive days of ANC < 500/mm 3 per cycle. In addition, patients must have experienced a clinically significant infection during the previous 12 months. Patients were randomized to a 4 month observation period followed by filgrastim treatment or immediate filgrastim treatment. The median age was 12 years (range 7 months to 76 years); 46% males; 34% idiopathic, 17% cyclic and 49% congenital neutropenia. Filgrastim was administered subcutaneously. The dose of filgrastim was determined by the category of neutropenia. Initial dose of filgrastim: • Idiopathic neutropenia: 3.6 mcg/kg/day • Cyclic neutropenia: 6 mcg/kg/day • Congenital neutropenia: 6 mcg/kg/day divided 2 times per day The dose was increased incrementally to 12 mcg/kg/day divided 2 times per day if there was no response. The main efficacy endpoint was response to filgrastim treatment. ANC response from baseline (< 500/mm 3 ) was defined as follows: • Complete response: median ANC > 1500/mm 3 • Partial response: median ANC ≥ 500/mm 3 and ≤ 1500/mm 3 with a minimum increase of 100% • No response: median ANC < 500/mm 3 There were 112 of 123 patients who demonstrated a complete or partial response to filgrastim treatment. Additional efficacy endpoints included a comparison between patients randomized to 4 months of observation and patients receiving filgrastim of the following parameters: • incidence of infection • incidence of fever • duration of fever • incidence, duration, and severity of oropharyngeal ulcers • number of days of antibiotic use The incidence for each of these 5 clinical parameters was lower in the filgrastim arm compared to the control arm for cohorts in each of the 3 major diagnostic categories. An analysis of variance showed no significant interaction between treatment and diagnosis‚ suggesting that efficacy did not differ substantially in the different diseases. Although filgrastim substantially reduced neutropenia in all patient groups‚ in patients with cyclic neutropenia‚ cycling persisted but the period of neutropenia was shortened to 1 day.

8.5 Geriatric Use Among 855 subjects enrolled in 3 randomized, placebo-controlled trials of filgrastim-treated patients receiving myelosuppressive chemotherapy, there were 232 subjects age 65 or older, and 22 subjects age 75 or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. Clinical studies of filgrastim in other approved indications (i.e., BMT recipients, PBPC mobilization, and SCN) did not include sufficient numbers of subjects aged 65 and older to determine whether elderly subjects respond differently from younger subjects.

8.4 Pediatric Use NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard may not accurately measure volumes less than 0.3 mL due to the needle spring mechanism design. Therefore, the direct administration of a volume less than 0.3 mL using NIVESTYM prefilled syringe is not recommended due to the potential for dosing errors. For direct administration of doses less than 0.3 mL (180 mcg) use NIVESTYM single-dose vial. In patients with cancer receiving myelosuppressive chemotherapy‚ 15 pediatric patients median age 2.6 (range 1.2 to 9.4) years with neuroblastoma were treated with myelosuppressive chemotherapy (cyclophosphamide‚ cisplatin‚ doxorubicin‚ and etoposide) followed by subcutaneous filgrastim at doses of 5, 10, or 15 mcg/kg/day for 10 days (n = 5/dose) (Study 8). The pharmacokinetics of filgrastim in pediatric patients after chemotherapy were similar to those in adults receiving the same weight-normalized doses, suggesting no age-related differences in the pharmacokinetics of filgrastim. In this population‚ filgrastim was well-tolerated. There was one report of palpable splenomegaly and one report of hepatosplenomegaly associated with filgrastim therapy; however‚ the only consistently reported adverse event was musculoskeletal pain‚ which is no different from the experience in the adult population. The safety and effectiveness of filgrastim have been established in pediatric patients with SCN [see Clinical Studies (14.5) ] . In a phase 3 study (Study 7) to assess the safety and efficacy of filgrastim in the treatment of SCN, 123 patients with a median age of 12 years (range 7 months to 76 years) were studied. Of the 123 patients, 12 were infants (7 months to 2 years of age), 49 were children (2 to 12 years of age), and 9 were adolescents (12 to 16 years of age). Additional information is available from a SCN postmarketing surveillance study, which includes long-term follow-up of patients in the clinical studies and information from additional patients who entered directly into the postmarketing surveillance study. Of the 731 patients in the surveillance study, 429 were pediatric patients < 18 years of age (range 0.9 to 17) [see Indications and Usage (1.5) , Dosage and Administration (2.5) , and Clinical Studies (14.5) ] . Long-term follow-up data from the postmarketing surveillance study suggest that height and weight are not adversely affected in patients who received up to 5 years of filgrastim treatment. Limited data from patients who were followed in the phase 3 study for 1.5 years did not suggest alterations in sexual maturation or endocrine function. Pediatric patients with congenital types of neutropenia (Kostmann's syndrome, congenital agranulocytosis, or Schwachman-Diamond syndrome) have developed cytogenetic abnormalities and have undergone transformation to MDS and AML while receiving chronic filgrastim treatment. The relationship of these events to filgrastim administration is unknown [see Warnings and Precautions (5.8) and Adverse Reactions (6) ] .

8.1 Pregnancy Risk Summary Available data from published studies, including several observational studies of pregnancy outcomes in women exposed to filgrastim products and those who were unexposed, have not established an association with filgrastim products use during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data ) . Reports in the scientific literature have described transplacental passage of filgrastim in pregnant women when administered ≤ 30 hours prior to preterm delivery (≤ 30 weeks gestation). In animal reproduction studies, effects of filgrastim on prenatal development have been studied in rats and rabbits. No malformations were observed in either species. No maternal or fetal effects were observed in pregnant rats at doses up to 58 times the human doses. Filgrastim has been shown to have adverse effects in pregnant rabbits at doses 2 to 10 times higher than the human doses (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Human data Several observational studies based on the Severe Chronic Neutropenia International Registry (SCNIR) described pregnancy outcomes in women with severe chronic neutropenia (SCN) who were exposed to filgrastim products during pregnancy and women with SCN who were unexposed. No major differences were seen between treated and untreated women with respect to pregnancy outcome (including miscarriage and preterm labor), newborn complications (including birth weight) and infections. Methodological limitations of these studies, include small sample size, and lack of generalizability due to the underlying maternal condition. Animal data Effects of filgrastim on prenatal development have been studied in rats and rabbits. No malformations were observed in either species. Filgrastim has been shown to have adverse effects in pregnant rabbits at doses 2 to 10 times higher than the human doses. In pregnant rabbits showing signs of maternal toxicity, reduced embryo-fetal survival (at 20 and 80 mcg/kg/day) and increased abortions (at 80 mcg/kg/day) were observed. In pregnant rats, no maternal or fetal effects were observed at doses up to 575 mcg/kg/day, which is approximately 58 times higher than the human dose of 10 mcg/kg/day. Offspring of rats administered filgrastim during the peri-natal and lactation periods exhibited a delay in external differentiation and growth retardation (≥ 20 mcg/kg/day) and slightly reduced survival rate (100 mcg/kg/day).

There are a few case reports describing the use of filgrastim products in breastfeeding mothers with no adverse effects noted in the infants. There are no data on the effects of filgrastim products on milk production. Other filgrastim products are secreted poorly into breast milk, and filgrastim products are not absorbed orally by neonates. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for NIVESTYM and any potential adverse effects on the breastfed child from NIVESTYM or from the underlying maternal condition. 8.4 Pediatric Use NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard may not accurately measure volumes less than 0.3 mL due to the needle spring mechanism design.
