PegF 6mg Injection

Pegfilgrastim is a leukocyte growth factor indicated to Decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia. Increase survival in patients acutely exposed to myelosuppressive doses of radiation (Hematopoietic Subsyndrome of Acute Radiation Syndrome). Limitations of Use Pegfilgrastim is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation. Patients with Cancer Receiving Myelosuppressive Chemotherapy Pegfilgrastim is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia. Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome Pegfilgrastim is indicated to increase survival in patients acutely exposed to myelosuppressive doses of radiation.

Fatal splenic rupture: Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture Acute respiratory distress syndrome (ARDS): Evaluate patients who develop fever, lung infiltrates, or respiratory distress. Discontinue Pegfilgrastim in patients with ARDS. Serious allergic reactions, including anaphylaxis: Permanently discontinue Pegfilgrastim in patients with serious allergic reactions. The on-body injector for Pegfilgrastim uses acrylic adhesives. For patients who have reactions to acrylic adhesives, use of this product may result in a significant reaction. Fatal sickle cell crises: Discontinue Pegfilgrastim if sickle cell crisis occurs. Glomerulonephritis: Evaluate and consider dose-reduction or interruption of Pegfilgrastim if causality is likely. Thrombocytopenia: Monitor platelet count Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML): Monitor patients with breast and lung cancer using Pegfilgrastim in conjunction with chemotherapy and/or radiotherapy for signs and symptoms of MDS/AML. Potential device failures: Instruct patients to notify their healthcare provider if they suspect the on-body injector may not have performed as intended. Splenic Rupture Splenic rupture, including fatal cases, can occur following the administration of pegfilgrastim products. Evaluate for an enlarged spleen or splenic rupture in patients who report left upper abdominal or shoulder pain after receiving Pegfilgrastim. Acute Respiratory Distress Syndrome Acute respiratory distress syndrome (ARDS) can occur in patients receiving pegfilgrastim products. Evaluate patients who develop fever and lung infiltrates or respiratory distress after receiving Pegfilgrastim for ARDS. Serious Allergic Reactions Serious allergic reactions, including anaphylaxis, can occur in patients receiving pegfilgrastim products. The majority of reported events occurred upon initial exposure. Allergic reactions, including anaphylaxis, can recur within days after the discontinuation of initial anti-allergic treatment. Permanently discontinue Pegfilgrastim in patients with serious allergic reactions. Do not administer Pegfilgrastim to patients with a history of serious allergic reactions to pegfilgrastim products or filgrastim products. Allergies to Acrylics The on-body injector (OBI) for Pegfilgrastim uses acrylic adhesive. Use in Patients with Sickle Cell Disorders Severe and sometimes fatal sickle cell crises can occur in patients with sickle cell disorders receiving pegfilgrastim products. Discontinue Pegfilgrastim if sickle cell crisis occurs. Glomerulonephritis has occurred in patients receiving pegfilgrastim products. The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Abridged from the full prescribing information.

The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: Splenic Rupture Acute Respiratory Distress Syndrome Serious Allergic Reactions Allergies to Acrylics Use in Patients with Sickle Cell Disorders Glomerulonephritis Leukocytosis Thrombocytopenia Capillary Leak Syndrome Potential for Tumor Growth Stimulatory Effects on Malignant Cells Myelodysplastic syndrome Acute myeloid leukemia Aortitis Most common adverse reactions (≥ 5% difference in incidence compared to placebo) are bone pain and pain in extremity. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Pegfilgrastim clinical trials safety data are based upon 932 patients receiving pegfilgrastim in seven randomized clinical trials. The population was 21 to 88 years of age and 92% female. The ethnicity was 75% Caucasian, 18% Hispanic, 5% Black, and 1% Asian. Patients with breast (n = 823), lung and thoracic tumors (n = 53) and lymphoma (n = 56) received pegfilgrastim after nonmyeloablative cytotoxic chemotherapy. Most patients received a single 100 mcg/kg (n = 259) or a single 6 mg (n = 546) dose per chemotherapy cycle over 4 cycles. The following adverse reaction data in Table 2 are from a randomized, double-blind, placebo-controlled study in patients with metastatic or non-metastatic breast cancer receiving docetaxel 100 mg/m 2 every 21 days (Study 3). A total of 928 patients were randomized to receive either 6 mg pegfilgrastim (n = 467) or placebo (n = 461). The patients were 21 to 88 years of age and 99% female. The ethnicity was 66% Caucasian, 31% Hispanic, 2% Black, and <1% Asian, Native American or other. The most common adverse reactions occurring in ≥ 5% of patients and with a between-group difference of ≥ 5% higher in the pegfilgrastim arm in placebo controlled clinical trials are bone pain and pain in extremity. Table 2. Adverse Reactions with ≥ 5% Higher Incidence in pegfilgrastim Patients Compared to Placebo in Study 3 Body System Adverse Reaction Placebo (N = 461) pegfilgrastim 6 mg SC on Day 2 (N = 467) Musculoskeletal and connective tissue disorders Bone pain 26% 31% Pain in extremity 4% 9% Leukocytosis In clinical studies, leukocytosis (WBC counts > 100 x 10 9 /L was observed in less than 1% of 932 patients with non-myeloid malignancies receiving pegfilgrastim.
