Warnings
5 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 evaluated in patients receiving concurrent radiation therapy. Avoid the simultaneous use of NYPOZI with chemotherapy and radiation therapy. 5.14 Nuclear Imaging Increased hematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone-imaging changes. This should be considered when interpreting bone-imaging results. 5.15 Aortitis Aortitis has been reported in patients receiving filgrastim products. It may occur as early as the first week after start of therapy. Manifestations may include generalized signs and symptoms such as fever, abdominal pain, malaise, back pain, and increased inflammatory markers (e.g., c-reactive protein and white blood cell count). Consider aortitis in patients who develop these signs and symptoms without known etiology. Discontinue NYPOZI if aortitis is suspected.

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 Postmarketing Experience The following adverse reactions have been identified during post-approval use of filgrastim products.
