Description
11 DESCRIPTION Pegfilgrastim-unne is a covalent conjugate of recombinant methionyl human G-CSF and monomethoxypolyethylene glycol. Recombinant methionyl human G-CSF is a water-soluble 175 amino acid protein with a molecular weight of approximately 19 kilodaltons (kD). Recombinant methionyl human G-CSF is obtained from the bacterial fermentation of a strain of E coli transformed with a genetically engineered plasmid containing the human G-CSF gene. To produce pegfilgrastim-unne, a 20 kD monomethoxypolyethylene glycol molecule is covalently bound to the N-terminal methionyl residue of recombinant methionyl human G-CSF. The average molecular weight of pegfilgrastim-unne is approximately 39 kD. Armlupeg (pegfilgrastim-unne) injection is a sterile, clear, colorless, preservative-free solution intended for subcutaneous use only and is supplied in a single-dose prefilled syringe with a 27‑gauge ½" needle and rigid needle shield, with UltraSafe Plus Passive TM Needle Guard. The prefilled syringe does not bear graduation marks and is designed to deliver the entire contents of the syringe (6 mg/0.6 mL). Each prefilled syringe contains 0.6 mL solution of 6 mg pegfilgrastim-unne (based on protein weight), glacial acetic acid (0.77 mg), polysorbate 20 (0.02 mg), sodium acetate (0.066 mg) and sorbitol (30 mg) in Water for Injection, USP. The pH is 4.
What Is Pegfilgrastim-Unne Used For?
1 INDICATIONS AND USAGE Armlupeg 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. (1.1) Increase survival in patients acutely exposed to myelosuppressive doses of radiation (Hematopoietic Subsyndrome of Acute Radiation Syndrome). (1.2) Limitations of Use Armlupeg is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation. 1.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy Armlupeg is indicated in adults and pediatric patients aged newborn and older 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 [see Clinical Studies (14.1)]. Limitations of Use Armlupeg is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation. 1.2 Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome Armlupeg is indicated to increase survival in adults and pediatric patients aged newborn and older acutely exposed to myelosuppressive doses of radiation [see Dosage and Administration (2.2) and Clinical Studies (14.2)] .
Dosage and Administration

6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: Splenic Rupture [see Warnings and Precautions (5.1)] Acute Respiratory Distress Syndrome [see Warnings and Precautions (5.2)] Serious Hypersensitivity Reactions [see Warnings and Precautions (5.3)] Use in Patients with Sickle Cell Disorders [see Warnings and Precautions (5.4)] Glomerulonephritis [see Warnings and Precautions (5.5)] Leukocytosis [see Warnings and Precautions (5.6)] Thrombocytopenia [see Warnings and Precautions (5.7)] Capillary Leak Syndrome [see Warnings and Precautions (5.8)] Potential for Tumor Growth Stimulatory Effects on Malignant Cells [see Warnings and Precautions (5.9)] Myelodysplastic syndrome [see Warnings and Precautions ( 5.10 )] Acute myeloid leukemia [see Warnings and Precautions ( 5.10 )] Aortitis [see Warnings and Precautions (5.11)] Most common adverse reactions (≥ 5% difference in incidence compared to placebo) are bone pain and pain in extremity. To report SUSPECTED ADVERSE REACTIONS, contact Valorum Biologics, LLC at 1-844-576-2709 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. *Biosimilar means that the biological product is approved based on data demonstrating that it is highly similar to an FDA-approved biological product, known as a reference product, and that there are no clinically meaningful differences between the biosimilar product and the reference product. Biosimilarity of Armlupeg has been demonstrated for the condition(s) of use (e.g., indication(s), dosing regimen(s)), strength(s), dosage form(s), and route(s) of administration described in its Full Prescribing Information. 6.1 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 1 are from a randomized, double-blind, placebo- controlled study in patients with metastatic or non-metastatic breast cancer receiving docetaxel 100 mg/m2 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 1. 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 >100x10 9 /L) was observed in less than 1% of 932 patients with non-myeloid malignancies receiving Pegfilgrastim. No complications attributable to leukocytosis were reported in clinical studies. 6.3 Postmarketing Experience The following adverse reactions have been identified during post approval use of Pegfilgrastim products. Because these reactions are reported voluntarily from a population of uncertain size, it...
Contraindications
4 CONTRAINDICATIONS Armlupeg is contraindicated in patients with a history of a serious hypersensitivity reaction to pegfilgrastim products or filgrastim products. Reactions have included anaphylaxis [see Warnings and Precautions (5.3)]. In patients with a history of serious hypersensitivity reaction to pegfilgrastim products or filgrastim products.
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Although available data with pegfilgrastim product use in pregnant women are insufficient to establish whether there is a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, there are available data from published studies in pregnant women exposed to filgrastim products. These studies have not established an association of filgrastim product use during pregnancy with major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal studies, no evidence of reproductive/developmental toxicity occurred in the offspring of pregnant rats that received cumulative doses of pegfilgrastim approximately 10 times the recommended human dose (based on body surface area). In pregnant rabbits, increased embryolethality and spontaneous abortions occurred at 4 times the maximum recommended human dose simultaneously with signs of maternal toxicity (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population 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 Animal data Pregnant rabbits were dosed with pegfilgrastim subcutaneously every other day during the period of organogenesis. At cumulative doses ranging from the approximate human dose to approximately 4 times the recommended human dose (based on body surface area), the treated rabbits exhibited decreased maternal food consumption, maternal weight loss, as well as reduced fetal body weights and delayed ossification of the fetal skull; however, no structural anomalies were observed in the offspring from either study. Increased incidences of post-implantation losses and spontaneous abortions (more than half the pregnancies) were observed at cumulative doses approximately...
Overdosage
10 OVERDOSAGE Overdosage of pegfilgrastim products may result in leukocytosis and bone pain. Events of edema, dyspnea, and pleural effusion have been reported in a single patient who administered pegfilgrastim on 8 consecutive days in error. In the event of overdose, the patient should be monitored for adverse reactions [see Adverse Reactions (6)]. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
