DOSAGE AND ADMINISTRATION Patients with cancer receiving myelosuppressive chemotherapy or induction and/or consolidation chemotherapy for AML Recommended starting dose is 5 mcg/kg/day by 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: 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 10 mcg/kg/day subcutaneous injection ( 2.3 ) Administer for at least 4 days before first leukapheresis procedure and continue until last leukapheresis ( 2.3 ) Patients with congenital neutropenia Recommended starting dose is 6 mcg/kg subcutaneous injection twice daily ( 2.4 ) Patients with cyclic or idiopathic neutropenia Recommended starting dose is 5 mcg/kg subcutaneous injection daily ( 2.4 ) Patients acutely exposed to myelosuppressive doses of radiation 10 mcg/kg/day subcutaneous injection ( 2.5 ) Direct administration of less than 0.3 mL (180 mcg) is not recommended due to potential for dosing errors ( 2.6 ) 2.1 Dosage in Patients with Cancer Receiving Myelosuppressive Chemotherapy or Induction and/or Consolidation Chemotherapy for AML The recommended starting dosage of NYPOZI 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 NYPOZI 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 NYPOZI if the ANC increases beyond 10‚000/mm 3 [see Warnings and Precautions (5.10) ]. Administer NYPOZI at least 24 hours after cytotoxic chemotherapy. Do not administer NYPOZI 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 filgrastim therapy. Therefore, to ensure a sustained therapeutic response‚ administer NYPOZI 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 NYPOZI 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 NYPOZI 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 NYPOZI 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 NYPOZI against the neutrophil response (see Table 1). Table 1. Recommended Dosage Adjustments During Neutrophil Recovery in Patients with Cancer Following BMT Absolute Neutrophil Count NYPOZI Dosage Adjustment a If ANC decreases to less than 1000/mm 3 at any time during the 5 mcg/kg/day administration‚ increase NYPOZI to 10 mcg/kg/day‚ and then follow the above steps. When ANC greater than 1,000/mm 3 for 3 consecutive days Reduce to 5 mcg/kg/day a Then, if ANC remains greater than 1,000/ mm 3 for 3 more consecutive days Discontinue NYPOZI Then, if ANC decreases to less than 1,000/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 NYPOZI for the mobilization of autologous peripheral blood progenitor cells (PBPC) is 10 mcg/kg/day given by subcutaneous injection. Administer NYPOZI for at least 4 days before the first leukapheresis procedure and continue until the last leukapheresis. Although the optimal duration of NYPOZI 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 NYPOZI and discontinue NYPOZI 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 NYPOZI 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 NYPOZI 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 NYPOZI 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 Dosage in Patients Acutely Exposed to Myelosuppressive Doses of Radiation (Hematopoietic Syndrome of Acute Radiation Syndrome) The recommended dose of NYPOZI is 10 mcg/kg as a single daily subcutaneous injection for patients exposed to myelosuppressive doses of radiation. Administer NYPOZI as soon as possible after suspected or confirmed exposure to radiation doses greater than 2 gray (Gy). Estimate a patient's absorbed radiation dose (i.e., level of radiation exposure) based on information from public health authorities, biodosimetry if available, or clinical findings such as time to onset of vomiting or lymphocyte depletion kinetics. Obtain a baseline CBC and then serial CBCs approximately every third day until the ANC remains greater than 1,000/mm 3 for 3 consecutive CBCs. Do not delay administration of NYPOZI if a CBC is not readily available. Continue administration of NYPOZI until the ANC remains greater than 1,000/mm 3 for 3 consecutive CBCs or exceeds 10,000/mm 3 after a radiation-induced nadir. 2.6 Important Administration Instructions NYPOZI is supplied in single-dose prefilled syringes (for subcutaneous or intravenous use) [see Dosage Forms and Strengths (3) ] . Prior to use‚ remove the prefilled syringe from the refrigerator and allow NYPOZI to reach room temperature for a minimum of 30 minutes and a maximum of 24 hours. Discard any 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 sol

WARNINGS AND PRECAUTIONS Fatal splenic rupture: Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture. ( 5.1 ) Acute respiratory distress syndrome (ARDS): Evaluate patients who develop fever and lung infiltrates or respiratory distress for ARDS. Discontinue NYPOZI in patients with ARDS. ( 5.2 ) Serious allergic reactions, including anaphylaxis: Permanently discontinue NYPOZI in patients with serious allergic reactions. ( 5.3 ) Fatal sickle cell crises: Discontinue NYPOZI if sickle cell crisis occurs. ( 5.4 ) Glomerulonephritis: Evaluate and consider dose-reduction or interruption of NYPOZI if causality is likely. ( 5.5 ) Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML): Monitor patients with breast and lung cancer using NYPOZI in conjunction with chemotherapy and/or radiotherapy for signs and symptoms of MDS/AML. ( 5.8 ) Thrombocytopenia: Monitor platelet counts. ( 5.9 ) 5.1 Splenic Rupture Splenic rupture, including fatal cases, has been reported following the administration of filgrastim products. Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture. 5.2 Acute Respiratory Distress Syndrome Acute respiratory distress syndrome (ARDS) has been reported in patients receiving filgrastim products. Evaluate patients who develop fever and lung infiltrates or respiratory distress for ARDS. Discontinue NYPOZI in patients with ARDS. 5.3 Serious Allergic Reactions Serious allergic reactions, including anaphylaxis, have been reported in patients receiving filgrastim products. The majority of reported events occurred upon initial exposure. Provide symptomatic treatment for allergic reactions. Allergic reactions, including anaphylaxis, in patients receiving filgrastim products can recur within days after the discontinuation of initial anti-allergic treatment. Permanently discontinue NYPOZI in patients with serious allergic reactions. NYPOZI is contraindicated in patients with a history of serious allergic reactions to human granulocyte colony-stimulating factors such as filgrastim products or pegfilgrastim products. 5.4 Sickle Cell Disorders Severe and sometimes fatal sickle cell crises can occur, in patients with sickle cell disorders receiving filgrastim products. Discontinue NYPOZI if sickle cell crisis occurs. 5.5 Glomerulonephritis Glomerulonephritis has occurred in patients receiving filgrastim products. The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Generally, events of glomerulonephritis resolved after dose-reduction or discontinuation of filgrastim products. If glomerulonephritis is suspected, evaluate for cause. If causality is likely, consider dose-reduction or interruption of NYPOZI. 5.6 Alveolar Hemorrhage and Hemoptysis Alveolar hemorrhage manifesting as pulmonary infiltrates and hemoptysis requiring hospitalization have been reported in healthy donors treated with filgrastim products undergoing peripheral blood progenitor cell (PBPC) collection mobilization. Hemoptysis resolved with discontinuation of filgrastim products. The use of NYPOZI for PBPC mobilization in healthy donors is not an approved indication. 5.7 Capillary Leak Syndrome Capillary leak syndrome (CLS) has been reported after G-CSF administration, including filgrastim products, and is characterized by hypotension, hypoalbuminemia, edema, and hemoconcentration. Episodes vary in frequency, severity and may be life-threatening if treatment is delayed. Patients who develop symptoms of capillary leak syndrome should be closely monitored and receive standard symptomatic treatment, which may include a need for intensive care. 5.8 Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) Patients with Severe Chronic Neutropenia Confirm the diagnosis of SCN before initiating NYPOZI therapy. MDS and AML have been reported to occur in the natural history of congenital neutropenia without cytokine therapy. Cytogenetic abnormalities, transformation to MDS, and AML have also been observed in patients treated with filgrastim products for SCN. Based on available data including a postmarketing surveillance study, the risk of developing MDS and AML appears to be confined to the subset of patients with congenital neutropenia. Abnormal cytogenetics and MDS have been associated with the eventual development of myeloid leukemia. The effect of filgrastim products on the development of abnormal cytogenetics and the effect of continued filgrastim products administration in patients with abnormal cytogenetics or MDS are unknown. Monitor patients for signs and symptoms of MDS/AML in these settings. If a patient with SCN develops abnormal cytogenetics or myelodysplasia‚ the risks and benefits of continuing NYPOZI should be carefully considered. Patients with Breast and Lung Cancer MDS and AML have been associated with the use of filgrastim products in conjunction with chemotherapy and/or radiotherapy in patients with breast and lung cancer. Monitor patients for signs and symptoms of MDS/AML in these settings. 5.9 Thrombocytopenia Thrombocytopenia has been reported in patients receiving filgrastim products. Monitor platelet counts. 5.10 Leukocytosis Patients with Cancer Receiving Myelosuppressive Chemotherapy White blood cell counts of 100‚000/mm 3 or greater were observed in approximately 2% of patients receiving filgrastim at dosages above 5 mcg/kg/day. In patients with cancer receiving NYPOZI as an adjunct to myelosuppressive chemotherapy‚ to avoid the potential risks of excessive leukocytosis‚ it is recommended that NYPOZI therapy be discontinued if the ANC surpasses 10‚000/mm 3 after the chemotherapy-induced ANC nadir has occurred. Monitor CBCs at least twice weekly during therapy. Dosages of NYPOZI that increase the ANC beyond 10‚000/mm 3 may not result in any additional clinical benefit. In patients with cancer receiving myelosuppressive chemotherapy‚ discontinuation of filgrastim therapy usually resulted in a 50% decrease in circulating neutrophils within 1 to 2 days‚ with a return to pretreatment levels in 1 to 7 days. Peripheral Blood Progenitor Cell Collection and Therapy During the period of administration of NYPOZI for PBPC mobilization in patients with cancer, discontinue NYPOZI if the leukocyte count rises to > 100,000/mm 3 . 5.11 Cutaneous Vasculitis Cutaneous vasculitis has been reported in patients treated with filgrastim products. In most cases‚ the severity of cutaneous vasculitis was moderate or severe. Most of the reports involved patients with SCN receiving long-term filgrastim therapy. Hold NYPOZI therapy in patients with cutaneous vasculitis. NYPOZI may be started at a reduced dose when the symptoms resolve and the ANC has decreased. 5.12 Potential Effect on Malignant Cells NYPOZI is a growth factor that primarily stimulates neutrophils. The granulocyte-colony stimulating factor (G-CSF) receptor through which NYPOZI acts has also been found on tumor cell lines. The possibility that NYPOZI acts as a growth factor for any tumor type cannot be excluded. The safety of filgrastim products in chronic myeloid leukemia (CML) and myelodysplasia has not been established. When NYPOZI is used to mobilize PBPC‚ tumor cells may be released from the marrow and subsequently collected in the leukapheresis product. The effect of reinfusion of tumor cells has not been well studied‚ and the limited data available are inconclusive. 5.13 Simultaneous Use with Chemotherapy and Radiation Therapy Not Recommended The safety and efficacy of NYPOZI given simultaneously with cytotoxic chemotherapy have not been established. Because of the potential sensitivity of rapidly dividing myeloid cells to cytotoxic chemotherapy‚ do not use NYPOZI in the period 24 hours before through 24 hours after the administration of cytotoxic chemotherapy [see Dosage and Administration (2.2) ]. The safety and efficacy of NYPOZI have not been e

CONTRAINDICATIONS RELEUKO 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 )

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.
