CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Eflapegrastim-xnst is 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.. 12.2 Pharmacodynamics Eflapegrastim-xnst has been shown to elevate neutrophil counts in healthy subjects and in cancer patients. Absolute neutrophil count (ANC), Cmax and area under the effect curve (AUEClast) increased with increasing doses of eflapegrastim-xnst in linear, but less than dose-proportional, manner over dose range of 45 to 350 mcg/kg.. 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.AbsorptionThe median Tmax of eflapegrastim-xnst is 25 hours (6 to 144 hours) in patients with breast cancer following administration of the recommended dosage.DistributionThe volume of distribution of eflapegrastim-xnst is 1.44 L.EliminationThe 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 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.MetabolismEflapegrastim-xnst is expected to be metabolized by endogenous degradation following receptor-mediated internalization by cells bearing the G-CSF receptor.ExcretionEflapegrastim-xnst was not detected in urine.Drug Interaction StudiesNo studies evaluating the drug interaction potential of eflapegrastim-xnst have been conducted.. 12.6 Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of eflapegrastim-xnst or of other eflapegrastim products.Antibodies to eflapegrastim-xnst were detected using bridging enzyme-linked immunosorbent assay (ELISA) with sensitivity of 65 ng/mL. During the 12-week treatment period in the two randomized studies, twenty-one of 297 (7.1%) patients treated with eflapegrastim-xnst developed antibodies. At the 12-month follow-up visit after the last dose of treatment in the two randomized studies, 28 of 297 (9.4%) patients treated with eflapegrastim-xnst developed antibodies.Neutralizing antibodies were detected by cell-based assay with sensitivity of 1.95 mcg/mL. One patient out of 297 (0.3%) in the eflapegrastim-xnst arm tested positive for neutralizing antibodies post-treatment. Treatment-emergent anti-PEG antibodies were detected by direct binding ELISA in 126 out of 268 patients (47%) treated with eflapegrastim-xnst. There was no identified clinically significant effect of anti-drug antibodies on pharmacokinetics, pharmacodynamics, safety or effectiveness of Rolvedon over the treatment duration of 12 weeks. There was no identified clinically significant effect of anti-drug antibodies on the safety profile of Rolvedon during the 12-month follow-up period after the last dose.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES Patients with Cancer Receiving Myelosuppressive ChemotherapyThe efficacy of Rolvedon to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs was evaluated in two 1:1 randomized, open-label, active-controlled non-inferiority studies of similar design (Study [NCT02643420] and Study [NCT02953340]) that enrolled total of 643 patients with early-stage breast cancer. Docetaxel 75 mg/m] and Study [NCT02953340]) that enrolled total of 643 patients with early-stage breast cancer. Docetaxel 75 mg/m2 and cyclophosphamide 600 mg/m2 (TC) were administered intravenously every 21 days (on Day of each cycle) for up to cycles. fixed dose of Rolvedon 13.2 mg/0.6 mL or pegfilgrastim (6 mg/0.6 mL) was administered subcutaneously on Day of each cycle after TC chemotherapy.The median age of patients enrolled in the two randomized studies was 60 years (Range: 24 to 88), the majority of patients were female (>99%), 77% were White and 12% were Black or African American.Study enrolled 406 patients; 196 patients to the Rolvedon arm and 210 patients to the pegfilgrastim arm. Study enrolled 237 patients; 118 patients to the Rolvedon arm and 119 patients to the pegfilgrastim arm. Efficacy for both trials was based on the duration of severe neutropenia (DSN) in Cycle 1.Efficacy results are shown in Table 2. In both studies, Rolvedon was non-inferior to pegfilgrastim. The distributions of the severe neutropenia events in percentage from Cycle for Study and Study are presented in Figure 1.Table 2. Duration of Severe Neutropenia (DSN) in Cycle (Study and Study 2) aConfidence intervals were obtained using 2.5 percentile and 97.5 percentile of the 100,000 bootstrap samples with treatment as stratification factor.The non-inferiority of Rolvedon to pegfilgrastim was to be declared if the upper bound of 95% CI of the difference in mean DSN between the treatment arms was <0.62 days.Study 1Study 2Rolvedon(n=196)Pegfilgrastim(n=210)Rolvedon(n=118)Pegfilgrastim(n=119)Mean DSN (SD) (Days)0.20 (0.503)0.35 (0.683)0.31 (0.688)0.39 (0.949)Median DSN (Range) (Days)0 (0, 3)0 (0, 3)0 (0, 3)0 (0, 7)Difference in DSN (Days)-0.148-0.07395% Confidence Intervala -0.265, -0.033-0.292, 0.129Figure 1.

PREGNANCY SECTION.

8.1 Pregnancy Risk SummaryThere are no available data on Rolvedon use in pregnant women; however, data from published studies with use of other recombinant human granulocyte colony-stimulating factor (rhG-CSF) products in pregnant women have not identified any drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.Animal reproduction studies were conducted in rats and rabbits. In rats, eflapegrastim-xnst did not adversely affect embryofetal and/or postnatal development when administered from organogenesis throughout lactation at doses that produced maternal exposures up to times the exposure at the recommended clinical dose. In rabbits, eflapegrastim-xnst caused embryofetal lethality and reduced fetal weight when administered during the organogenesis period at approximately times the exposure at the clinical dose (see Data).The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have 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.DataAnimal DataIn an embryofetal developmental study in rabbits, eflapegrastim-xnst was administered subcutaneously every other day during the period of organogenesis at doses up to 10 times the clinical exposure at the maximum recommended dose of 13.2 mg. Increased post-implantation loss, reduced number of live fetuses, and reduced fetal body weights were observed at times the clinical exposure, based on AUC. No malformations were observed up to 10 times the clinical exposure, based on AUC.In an embryofetal developmental study in rats, eflapegrastim-xnst administered subcutaneously every other day during the period of organogenesis did not adversely affect embryofetal development at doses up to times clinical exposure, based on AUC.In pre- and post-natal development study in rats, eflapegrastim-xnst administered subcutaneously once weekly from organogenesis through lactation did not adversely affect behavioral, developmental, or reproductive parameters at doses up to times the clinical exposure, based on AUC.

SPL PATIENT PACKAGE INSERT SECTION.

PATIENT INFORMATIONROLVEDON(R) (roll veh don)(eflapegrastim-xnst)injectionWhat is RolvedonRolvedon is man-made form of granulocyte colony-stimulating factor (G-CSF). G-CSF is substance produced by the body. It stimulates the growth of neutrophils, type of white blood cell important in the bodys fight against infection.It is not known if Rolvedon is safe and effective in children.Do not take Rolvedon if you have had serious allergic reaction to eflapegrastim, pegfilgrastim or filgrastim products.Before receiving Rolvedon, tell your healthcare provider about all of your medical conditions, including if you: have sickle cell disorder have kidney problems are pregnant or plan to become pregnant. It is not known if Rolvedon can harm your unborn baby. Tell your healthcare provider right away if you become pregnant during treatment with Rolvedon. are breastfeeding or plan to breastfeed. It is not known if Rolvedon passes into your breast milk.Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.How will receive Rolvedon Rolvedon is given as an injection under your skin (subcutaneous injection) by healthcare provider. If your healthcare provider decides that the subcutaneous injections can be given at home by you or your caregiver, follow the detailed Instructions for Use that comes with your Rolvedon for information on how to prepare and inject dose of Rolvedon. You and your caregiver will be shown how to prepare and inject Rolvedon before you use it. You will receive injection of Rolvedon for each cycle of chemotherapy. You will receive your injection of Rolvedon about 24 hours after you finish receiving your chemotherapy. You should not receive Rolvedon for 14 days before or within 24 hours after your dose of chemotherapy. If you miss dose of Rolvedon, talk to your healthcare provider about when you should receive your next dose.What are the possible side effects of RolvedonRolvedon may cause serious side effects, including: Spleen rupture. Your spleen may become enlarged and can rupture. ruptured spleen can cause death. Call your healthcare provider right away if you have pain in the left upper stomach-area or your left shoulder. A serious lung problem called Acute Respiratory Distress Syndrome (ARDS). Call your healthcare provider or get emergency help right away if you have shortness of breath with or without fever, trouble breathing, or fast rate of breathing. Serious allergic reactions. Rolvedon can cause serious allergic reactions. These reactions can cause rash all over your whole body, shortness of breath, wheezing, dizziness, swelling around your mouth or eyes, fast heart rate, and sweating. If you have any of these symptoms, stop using Rolvedon and call your healthcare provider or get emergency medical help right away. Sickle cell crises.

Other recombinant human granulocyte colony-stimulating factor (rhG-CSF) products are present in human milk at low levels and are not orally absorbed by infants. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Rolvedon and any potential adverse effects on the breastfed child from Rolvedon or from the underlying maternal condition.. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.. 8.5 Geriatric Use Of the 314 patients in clinical studies of Rolvedon, 39% were 65 and over, while 6% were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.

(5.6)oThrombocytopenia: Monitor platelet counts. (5.7)oMyelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML): Monitor patients with breast and lung cancer using Rolvedon in conjunction with chemotherapy and/or radiotherapy for signs and symptoms of MDS/AML. (5.10). oFatal splenic rupture: Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture. (5.1). oAcute respiratory distress syndrome (ARDS): Evaluate patients who develop fever, lung infiltrates, or respiratory distress. Discontinue Rolvedon in patients with ARDS. (5.2). oSerious allergic reactions, including anaphylaxis: Permanently discontinue Rolvedon in patients with serious allergic reactions. (5.3). oSickle Cell Crisis in Patients with Sickle Cell Disorders: Discontinue Rolvedon if sickle cell crisis occurs. (5.4). oGlomerulonephritis: Evaluate and consider dose-reduction or interruption of Rolvedon if causality is likely. (5.5). oLeukocytosis: Monitor complete blood count (CBC) during Rolvedon therapy. (5.6). oThrombocytopenia: Monitor platelet counts. (5.7). oMyelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML): Monitor patients with breast and lung cancer using Rolvedon in conjunction with chemotherapy and/or radiotherapy for signs and symptoms of MDS/AML. (5.10). 5.1 Splenic Rupture Splenic rupture, including fatal cases, can occur following the administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) products, such as Rolvedon. Evaluate for an enlarged spleen or splenic rupture in patients who report left upper abdominal or shoulder pain after receiving Rolvedon.. 5.2 Acute Respiratory Distress Syndrome Acute respiratory distress syndrome (ARDS) can occur in patients receiving rhG-CSF products, such as Rolvedon. Evaluate patients who develop fever and lung infiltrates or respiratory distress after receiving Rolvedon for ARDS. Discontinue Rolvedon in patients with ARDS.. 5.3 Serious Allergic Reactions Serious allergic reactions, including anaphylaxis, can occur in patients receiving rhG-CSF products, such as Rolvedon. Permanently discontinue Rolvedon in patients with serious allergic reactions. Rolvedon is contraindicated in patients with history of serious allergic reactions to eflapegrastim, pegfilgrastim, or filgrastim products [see Contraindications (4)]. 5.4 Sickle Cell Crisis in Patients with Sickle Cell Disorders Severe and sometimes fatal sickle cell crises can occur in patients with sickle cell disorders receiving rhG-CSF products, such as Rolvedon. Discontinue Rolvedon if sickle cell crisis occurs.. 5.5 Glomerulonephritis Glomerulonephritis has occurred in patients receiving rhG-CSF 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 rhG-CSF. If glomerulonephritis is suspected, evaluate for cause. If causality is likely, consider dose-reduction or interruption of Rolvedon.. 5.6 Leukocytosis White blood cell (WBC) counts of 100 109/L or greater have been observed in patients receiving rhG-CSF products. Monitor complete blood count (CBC) during Rolvedon therapy. Discontinue Rolvedon treatment if WBC count of 100 109/L or greater occurs.. 5.7 Thrombocytopenia Thrombocytopenia has been reported in patients receiving rhG-CSF products. Monitor platelet counts.. 5.8 Capillary Leak Syndrome Capillary leak syndrome has been reported after administration of rhG-CSF products and is characterized by hypotension, hypoalbuminemia, edema and hemoconcentration. Episodes vary in frequency and 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 need for intensive care.. 5.9 Potential for Tumor Growth Stimulatory Effects on Malignant Cells. The granulocyte colony-stimulating factor (G-CSF) receptor through which Rolvedon acts has been found on tumor cell lines. The possibility that Rolvedon acts as growth factor for any tumor type, including myeloid malignancies and myelodysplasia, diseases for which Rolvedon is not approved, cannot be excluded.. 5.10 Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) in Patients with Breast and Lung Cancer. MDS and AML have been associated with the use of rhG-CSF 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.. 5.11 Aortitis Aortitis has been reported in patients receiving rhG-CSF 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 Rolvedon if aortitis is suspected.. 5.12 Nuclear Imaging Increased hematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone imaging findings. This should be considered when interpreting bone imaging results.
