About This Medication

11 DESCRIPTION Eflapegrastim-xnst is a granulocyte colony-stimulating factor (G‑CSF) produced by covalent coupling of a human G-CSF analog (18.6 kDa) and an Fc fragment of human immunoglobulin G4 (IgG4) (49.8 kDa), both derived from recombinant E. coli , via a single 3.4 kDa polyethylene glycol linker. The recombinant G-CSF domain in eflapegrastim-xnst is a variant of human G-CSF with two serine substitutions at positions 17 and 65, and no additional N-terminal methionine. Eflapegrastim-xnst has a molecular weight of approximately 72 kDa. Rolvedon (eflapegrastim-xnst) injection is a sterile, preservative-free, clear, colorless solution supplied in a single-dose prefilled syringe for subcutaneous use. Each 0.6 mL single-dose prefilled syringe contains 13.2 mg of eflapegrastim-xnst, citric acid monohydrate (2.52 mg), mannitol (30 mg), polysorbate 80 (0.72 mg) and sodium chloride (5.26 mg) in Water for Injection. Sodium hydroxide may be used to adjust pH to 5.5 during manufacturing.

กลไกการทำงาน

12.1 Mechanism of Action Eflapegrastim-xnst is a recombinant human granulocyte growth factor that binds to G-CSF receptors on myeloid progenitor cells and neutrophils, triggering signaling pathways that control cell differentiation, proliferation, migration and survival.

2 DOSAGE AND ADMINISTRATION • Recommended Dose: 13.2 mg administered subcutaneously once per chemotherapy cycle. ( 2.1 ) • Administer approximately 24 hours after cytotoxic chemotherapy. Do not administer within the period from 14 days before to 24 hours after administration of cytotoxic chemotherapy. ( 2.1 ) 2.1 Recommended Dosage The recommended dosage of Rolvedon is a single subcutaneous injection of 13.2 mg administered once per chemotherapy cycle. Administer approximately 24 hours after cytotoxic chemotherapy. Do not administer within the period from 14 days before to 24 hours after administration of cytotoxic chemotherapy. 2.2 Administration Rolvedon is administered subcutaneously via a single-dose prefilled syringe. Prior to use‚ take the carton out of the refrigerator and place the sealed blister tray on a clean flat surface for a minimum of 30 minutes to allow the product to reach room temperature. Do not warm up the prefilled syringe in any other way. Discard any prefilled syringe left at room temperature for greater than 72 hours. Do not shake. If Rolvedon is accidentally frozen, do not use. Remove the tray from box and carefully remove the prefilled syringe from the tray. If you drop the prefilled syringe onto a hard surface, do not use it. Use a new syringe for the injection. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer Rolvedon if discoloration or particulates are observed. Administer the entire contents of the prefilled syringe. If the patient or caregiver misses a dose of Rolvedon, instruct them to contact their healthcare provider. The Rolvedon prefilled syringe does not bear graduation marks and is intended only to deliver the entire contents of the syringe (13.2 mg/0.6 mL) for direct administration. Not made with natural rubber latex.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact 1-800-518-1084 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 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 to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of Rolvedon was evaluated in Study 1 and Study 2 [see Clinical Studies ( 14 )]. Patients with early-stage breast cancer received Rolvedon 13.2 mg by subcutaneous injection (n=314) or pegfilgrastim 6 mg by subcutaneous injection (n=326) on Day 2 of each cycle after docetaxel 75 mg/m 2 and cyclophosphamide 600 mg/m 2 (TC) chemotherapy. Among patients receiving Rolvedon, a total of 272 patients received four 21-day treatment cycles. The most common adverse reactions (≥20%) were fatigue, nausea, diarrhea, bone pain, headache, pyrexia, anemia, rash, myalgia, arthralgia, and back pain. Table 1 summarizes the adverse reactions that occurred in Studies 1 and 2. Table 1.

12.3 Pharmacokinetics The pharmacokinetics of eflapegrastim-xnst was studied in healthy subjects and patients with breast cancer. After subcutaneous (SC) dosing, the pharmacokinetics of eflapegrastim-xnst was nonlinear and exposure increases were not dose-proportional over the dose range of 45 to 350 mcg/kg. Absorption The median T max of eflapegrastim-xnst is 25 hours (6 to 144 hours) in patients with breast cancer following administration of the recommended dosage. Distribution The volume of distribution of eflapegrastim-xnst is 1.44 L. Elimination The geometric mean half-life of eflapegrastim-xnst in patients with breast cancer is 36.4 hours (Range: 16.1 to 115 hours) during Cycle 1. Eflapegrastim-xnst clearance decreased with increasing doses following single dose administration, suggesting target-mediated clearance of eflapegrastim-xnst by neutrophils. Following repeat administration, clearance increased in Cycle 3 as compared to Cycle 1, potentially due to the subsequent increase in neutrophils. In in vitro studies, the IgG4 Fc fragment in eflapegrastim-xnst binds to the neonatal Fc receptor (FcRn), facilitating the FcRn-mediated transcytosis of eflapegrastim-xnst. Metabolism Eflapegrastim-xnst is expected to be metabolized by endogenous degradation following receptor-mediated internalization by cells bearing the G-CSF receptor. Excretion Eflapegrastim-xnst was not detected in urine. Drug Interaction Studies No studies evaluating the drug interaction potential of eflapegrastim-xnst have been conducted.
