Abstract
PURPOSE To study the effects of delaying pegfilgrastim administration following high-dose cytarabine (HiDAC) consolidation in AML patients on time to neutrophil count recovery, infectious complications, and survival. METHODS Single-center retrospective chart review of 55 patients receiving pegfilgrastim as early administration (within 72 h) or delayed administration (after 72 h) of HiDAC. RESULTS The difference in neutrophil recovery time was similar between the early and delayed groups (18 days versus 19 days, p < 0.28). Infections were seen in four patients in the early administration group following chemotherapy compared to none in the delayed group (p = 0.04). Febrile neutropenia rates were also decreased in the delayed administration group (23.1% versus 10.3%, p = 0.28) as well as a trend towards longer median survival (16 months versus 19 months, p = 0.69) and overall survival (21 months versus 31 months, p = 0.47). CONCLUSION A difference in time to neutrophil recovery was not observed between the early and delayed administration groups yet decreased infectious complications may support the delayed administration of pegfilgrastim in these patients.

Abstract
In the development of biosimilar products to Neulasta, it is essential to determine the intact molecular mass and confirm precise PEGylation sites. In this study, we applied a combination of techniques, including post-column addition of triethylamine in reversed-phase liquid chromatography-mass spectrometry (RPLC-MS) to determine the intact molecular mass, and in-source fragmentation (ISF) and higher-energy collision dissociation-tandem mass spectrometry (HCD-MS/MS) to identify the PEGylation site. Our results show that both the pegfilgrastim biosimilar candidate and Neulasta lots are mono-PEGylated at the N-terminal end. Furthermore, we show that the combined ISF and HCD-MS/MS method can be used for identifying the PEGylation sites in the diPEGylated variant of pegfilgrastim. The diPEGylated variant has modification sites at the N-terminal end and a lysine at position 35 in the protein sequence.

Abstract
AIMS Breast cancer patients on chemotherapy who receive pegfilgrastim to prevent neutropenia may experience severe bone pain as a side effect. Traditional treatment recommendations include nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, opioids, and/or antihistamine use. However, little research was found comparing these interventions. The study aim was to address the gaps in literature and to explore the use of and perceived effectiveness of loratadine versus acetaminophen or NSAIDs in women with breast cancer treated with pegfilgrastim. This study also sought to understand how patients became aware of loratadine or other treatments for management of bone pain. DESIGN/METHODS This cross-sectional study used survey methods to collect data from 66 adult female breast cancer patients receiving chemotherapy with pegfilgrastim. RESULTS The incidence of bone pain was 45% (n = 30) in our sample, but more than half (n = 45; 69%) of the women took either acetaminophen, NSAIDs, or loratadine alone or in combination to prevent bone pain. All medication were rated as effective by patients, with acetaminophen slightly more effective than loratadine, and loratadine more effective than NSAIDs. CONCLUSIONS Acetaminophen, NSAIDs, and loratadine are easily available and inexpensive. However, unlike acetaminophen and NSAIDs, loratadine is dosed once a day and well tolerated with minimal adverse effects. CLINICAL IMPLICATIONS Randomized controlled trials are needed to adequately assess the effectiveness of all three medication options. Because little is known about optimal use of any of these medications for pegfilgrastim-induced bone pain, it is also important to identify the optimal time to initiate treatment and ideal treatment duration.

Abstract
Ramucirumab plus docetaxel (RD) can cause febrile neutropenia (FN), which frequently requires the prophylactic administration of pegfilgrastim. However, the effects of prophylactic pegfilgrastim on FN prevention, therapeutic efficacy, and prognosis after RD have not been fully evaluated in patients with advanced non-small-cell lung cancer (NSCLC). Two hundred and eighty-eight patients with advanced NSCLC who received RD as second-line therapy after platinum-based chemotherapy plus PD-1 blockade were included. Patients were divided into groups with and without prophylactic pegfilgrastim, and adverse events, efficacy, and prognosis were compared between both groups. Of the 288 patients, 247 received prophylactic pegfilgrastim and 41 did not. The frequency of grade 3/4 neutropenia was 62 patients (25.1%) in the pegfilgrastim group and 28 (68.3%) in the control group (p < 0.001). The frequency of FN was 25 patients (10.1%) in the pegfilgrastim group and 10 (24.4%) in the control group (p = 0.018). The objective response rate was 31.2% and 14.6% in the pegfilgrastim and control groups (p = 0.039), respectively. The disease control rate was 72.9% in the pegfilgrastim group and 51.2% in the control group (p = 0.009). Median progression free survival was 4.3 months in the pegfilgrastim group and 2.5 months in the control group (p = 0.002). The median overall survival was 12.8 and 8.1 months in the pegfilgrastim and control groups (p = 0.004), respectively. Prophylactic pegfilgrastim for RD reduced the frequency of grade 3/4 neutropenia and febrile neutropenia and did not appear to be detrimental to patient outcome RD.Clinical Trial Registration Number: UMIN000042333.

Abstract
BACKGROUND Neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy is a new standard for locally advanced esophageal squamous cell carcinoma. The optimal timing of pegfilgrastim with the DCF regimen to prevent febrile neutropenia (FN) remains controversial. The effectiveness of concomitant pegfilgrastim administration with continuous 5-fluorouracil (5-FU) infusion in the DCF regimen was therefore assessed. METHODS All patients who received neoadjuvant DCF for esophageal cancer were retrospectively assessed. Patients who had been scheduled to receive pegfilgrastim on days 3-5 (early group) or days 7-9 (regular group) of the DCF regimen were included. Uni- and multivariate analyses were used to assess risk factors for FN. RESULTS Eighty-eight patients were included in the analysis. The 26 patients in the early group received pegfilgrastim as scheduled. In the 62 patients of the regular group, 51 received pegfilgrastim at a median of 7 days after starting DCF chemotherapy. However, 11 patients in the regular group could not receive pegfilgrastim. Twenty-two patients of the regular group and 2 patients of the early group developed FN after the first session of DCF. Early administration of pegfilgrastim and grade 4 neutropenia were significantly associated with onset of FN, with multivariate analysis identifying early administration of pegfilgrastim as an independent preventive factor and grade 4 neutropenia as a risk factor, after adjusting for sex and age. CONCLUSION Early pegfilgrastim administration is a safe approach that reduces the incidence of FN in DCF therapy. Using pegfilgrastim with continuous 5-FU infusion in the DCF regimen represents a reasonable option to prevent FN.

Abstract
We herein report that filgrastim product Neupogen® and the filgrastim formulation buffer induced aggregate formation when mixed in vitro with human plasma, and formation of large membranous erythrocyte aggregates when mixed with human blood, similar to the aggregation induced by pegfilgrastim and by pegfilgrastim buffer [T. Arvinte, E. Poirier, N. Ersayin, G. Darpin, A. Cudd, J. Dowd, S. Brokx, Aggregation of human plasma and of human blood induced in vitro by pegfilgrastim originator formulation buffer and pegfilgrastim products, Eur. J. Pharmaceut. Biopharmaceut. (2023), doi: 10.1016/j.ejpb.2023.10.019]. The data identify the filgrastim buffer (which is practically the same in filgrastim and pegfilgrastim products) as the main driver of human plasma and blood aggregation. Kinetic experiments showed differences in the extent of plasma aggregation induced by a filgrastim product manufactured in EU and one manufactured in USA. Human donor variability in the plasma aggregation induced by filgrastim was observed. To study the effect of PEGylation of the filgrastim protein on plasma aggregation we compared filgrastim (Neupogen®) with pegfilgrastim (Neulasta®) solutions at the same protein concentration. These data show that PEGylation has a beneficial effect in inhibiting to an extent plasma aggregation. Interestingly, 20 kDa polyethylene glycol in the filgrastim buffer induced more plasma aggregation compared to the buffer, similar to the aggregation induced by pegfilgrastim. For intravenous infusion filgrastim solutions (300 µg/ml, vials only) may be diluted in 5 % dextrose from a concentration of 300 µg/ml to 5 µg/ml. Aggregation of human plasma was also induced by filgrastim solutions diluted in 5 % dextrose to 50 µg/ml, 15 µg/ml and 5 µg/ml filgrastim, as well as by the filgrastim buffer similarly diluted in 5 % dextrose (1:6, 1:20 and 1:60 dilution). These data show that filgrastim solutions used for intravenous administration in patients induce human plasma aggregation in vitro. Such aggregation phenomena may be related to known infusion side effects of filgrastim therapy.

Abstract
PURPOSE A high risk of febrile neutropenia (FN) from neoadjuvant chemotherapy with docetaxel, cisplatin, and fluorouracil (DCF) for esophageal cancer has been reported. The optimal timing of prophylactic use of pegfilgrastim remains to be elucidated. To evaluate the effect of pegfilgrastim administered on day 3, we conducted a feasibility study. METHODS Chemotherapy consisted of intravenous administration of docetaxel (70 mg/m2 per day) and cisplatin (70 mg/m2 per day) on day 1 and continuous infusion of 5-fluorouracil (750 mg/m2 per day) on days 1-5. Pegfilgrastim was given as a single subcutaneous injection at a dose of 3.6 mg on day 3 during each treatment course. This regimen was repeated every 3 weeks for up to a maximum of three courses. Prophylactic antibiotics were not needed but were allowed to be given at the discretion of the physician. The primary endpoint was the incidence of FN. RESULTS Twenty-six patients were administered DCF in combination with pegfilgrastim on day 3. After the first course of DCF, 10 out of 26 patients (38.5%) experienced grade 4 neutropenia, and two patients (7.7%) experienced FN. Of the 14 patients who did not receive prophylactic antibiotics, four had grade 4 neutropenia, including two who developed FN. On the contrary, of the 12 patients who received prophylactic levofloxacin, six had grade 4 neutropenia, but no cases of FN were observed. CONCLUSION Administration of pegfilgrastim on day 3 was not sufficient to prevent FN due to DCF treatment, and prophylactic administration of both pegfilgrastim and antibiotics could be a solution.

Abstract
INTRODUCTION The Ohio State University Comprehensive Cancer Center (The James) uses daily subcutaneous filgrastim as the inpatient granulocyte colony-stimulating factor of choice. The coordination of care associated with filgrastim can often be a barrier to patient discharge. The purpose of this study was to compare the inpatient cost of daily filgrastim to single dose pegfilgrastim and biosimilars. METHODS Adult patients admitted to The James who received at least one dose of filgrastim between June 1, 2021 and August 31, 2021 were retrospectively identified. This study compared the inpatient cost of filgrastim and biosimilars associated with one chemotherapy cycle to the potential inpatient cost of pegfilgrastim and biosimilars based on average sales price (ASP). Additionally, the number and duration of discharge prescriptions for filgrastim was determined. RESULTS Of the 44 unique patient encounters that met inclusion criteria, 19 received 300-mcg doses of filgrastim and 25 received 480-mcg doses. The median number of doses administered per admission was eight. If each of these patients were to instead receive the most inexpensive biosimilar, pegfilgrastim reference product, the cost would be 216% higher than with filgrastim-sndz. At discharge, 15 patients (34%) received a prescription for filgrastim to be continued for a median duration of 6 days. CONCLUSION Based on ASP, pegfilgrastim was more costly than filgrastim. Potential rebates and negotiation power may alter the financial outlook of adding pegfilgrastim to inpatient formulary. Exploration of delays in discharge due to insurance coordination for filgrastim continuation in the outpatient setting may also impact formulary decisions.

Abstract
Pegfilgrastim is administered as an adjunct to chemotherapy to reduce the incidence of febrile neutropenia and associated infectious complications. Lupin's Pegfilgrastim is a proposed biosimilar to the U.S.-referenced Neulasta®. Demonstration of biosimilarity requires extensive physicochemical and functional characterization of the biosimilar, and demonstration of analytical similarity to the reference product, in addition to clinical studies. This work is a case study for demonstrating the analytical similarity of Armlupeg (Lupin's Pegfilgrastim) to Neulasta® with respect to structural and physicochemical attributes using several robust, orthogonal, and state-of-the-art techniques including high-end liquid chromatography, mass spectrometry, and spectroscopy techniques; circular dichroism; differential scanning calorimetry; nuclear magnetic resonance; analytical ultracentrifugation; and micro-flow imaging. Functional similarity was demonstrated using an in vitro cell proliferation assay to measure relative potency and surface plasmon resonance to measure receptor binding kinetics. Furthermore, comparative forced-degradation studies were performed to study the degradation of the products under stress conditions. The product attributes were ranked based on a critical quality attributes risk score according to their potential clinical impact. Based on criticality, all analyses were statistically evaluated to conclude analytical similarity. Lupin's Pegfilgrastim was comparable to Neulasta® as demonstrated via structural, functional, and purity analyses. Lupin's Pegfilgrastim complied with the quality and statistical ranges established using Neulasta®. Both products follow the same degradation pathways under stress conditions as observed in the forced-degradation studies. No new impurity or degradation product was observed in Lupin's Pegfilgrastim. These data conclusively demonstrate the analytical similarity of Lupin's Pegfilgrastim and Neulasta®.

Abstract
BACKGROUND AND OBJECTIVES Myelosuppressive chemotherapy is effective for breast cancer but carries a potential risk of febrile neutropenia (FN). Clinical practice guidelines have recommended prophylaxis with granulocyte colony-stimulating factor (G-CSF) to reduce the incidence of FN in patients receiving chemotherapy. We aimed to examine the use of G-CSFs for primary prophylaxis for FN and to see whether it follows the guidelines. In addition, we examined the changes in the use of long-acting and short-acting G-CSFs in patients with breast cancer over the past ten years. METHODS This was a retrospective observational real-world study. The data were obtained from the clinical research database of three hospitals affiliated with Taipei Medical University. Patients with breast cancer who initiated their first chemotherapy regimen between January 1, 2011, and December 31, 2020, were identified by the ICD codes and their use of filgrastim or pegfilgrastim was identified by the Anatomical Therapeutic Chemical codes. Whether and how G-CSF was prescribed during the study patients' first chemotherapy regimen was examined, and the annual change in the total number of short- and long-acting G-CSFs prescribed to the study patients from 2011 to 2020 was analyzed. RESULTS Among the 2,444 patients who were prescribed at least one of the examined 15 breast cancer chemotherapy drugs, 1,414 did not use any G-CSFs during their first chemotherapy regimen while 145 used G-CSFs for primary prophylaxis and 185 for treatment. Among the patients receiving high FN risk regimens, only 8.6% used G-CSF for primary prophylaxis. The average (± SD) number of days for short-acting G-CSF use was 2.3 (± 1.5) days with a median of 2 days. In addition, it was found that there was a significant reduction in long-acting G-CSF use (p = 0.03) whereas the changes in short-acting G-CSF use over time were not significant (p = 0.50). CONCLUSIONS Our study results show that G-CSFs are used for primary prophylaxis in a small percentage of patients with breast cancer and the duration of short-acting G-CSF use is relatively short. Considering the significant clinical and economic impact of FN, it is hoped that the prescription patterns of G-CSFs observed can provide an important reference for future clinical practice and reimbursement policy.

Abstract
A vast number of therapeutic proteins are approved and available on the market. However, there are very limited analytical approaches available for the rapid determination of primary and higher-order structures which can be utilized for counterfeit identification. In the present study, filgrastim biosimilar products from different manufacturers were considered for developing discriminative orthogonal analytical techniques to determine structural variations. The developed intact mass analytical method and peptide mapping through LC-HRMS were able to differentiate three biosimilars based on deconvoluted mass and possible structural modification, respectively. Another structural attribute employed was charge heterogeneity through isoelectric focusing, which provides a snapshot of the presence of charge variants/impurities and was able to differentiate various marketed formulations of filgrastim. These three techniques can certainly differentiate the products that contain counterfeit drugs due to their capability concerning selectivity. Additionally, a unique HDX technique on LC-HRMS was developed, which can determine the labile hydrogen exposed to deuterium exchange in a specified time. HDX aids in identifying the workup process or changes in the host cell in the counterfeit product by differentiating the protein based on its higher-order structure.

Abstract
Therapeutic proteins, known as biologicals, are an important and growing class of drugs for treatment of a series of human ailments. Amino acid sequence variants of therapeutic proteins can affect their safety and efficacy. Top-down mass spectrometry is well suited for the sequence analysis of intact therapeutic proteins. Fine-tuning of tandem mass spectrometry (MS/MS) fragmentation conditions is essential for maximizing the amino acid sequence coverage but is often time-consuming. We used topdownr, an automated and integrated multimodal approach to systematically assess high mass accuracy MS/MS fragmentation parameters to characterize filgrastim, a 19 kDa recombinant human granulocyte colony-stimulating factor used in treating neutropenia. A total of 276 different MS/MS conditions were systematically tested, including the following parameters: protein charge state, HCD and CID collision energy, ETD reaction time, ETD supplemental activation, and UVPD activation time. Stringent and accurate evaluation and annotation of the MS/MS data was achieved by requiring a fragment ion mass error of 5 ppm, considering reproducible N- and C-terminal fragment ions only, and excluding internal fragment ion assignments. We report the first EThcD and UVPD MS/MS analysis of intact filgrastim, and these two techniques combined resulted in 98% amino acid sequence coverage. By combining all tested fragmentation modes, we obtained near-complete amino acid sequence coverage (99.4%) of intact filgrastim.

Abstract
PURPOSE The dose-limiting factor of ramucirumab plus docetaxel (RAM + DTX) in patients with non-small cell lung cancer (NSCLC) is febrile neutropenia (FN), which has a high incidence in Asians. This study aimed to evaluate the cost-effectiveness of pegfilgrastim (Peg-G) in patients with NSCLC receiving RAM + DTX in Japan. METHODS We simulated model patients treated with RAM + DTX in Japan and developed a decision-analytical model for patients receiving Peg-G prophylaxis or no primary prophylaxis. The expected cost, quality-adjusted life-year (QALY), and incremental cost-effectiveness ratio (ICER) of each treatment were calculated from the perspective of a Japanese healthcare payer. The willingness-to-pay (WTP) threshold was set at 45,867 United States dollars (USD) (5 million Japanese yen) per QALY gained. The probabilities, utility values, and other costs were obtained from published sources. Deterministic sensitivity analysis (DSA) and probabilistic analysis were conducted to evaluate the effect of each parameter and robustness of the base-case results. RESULTS The expected cost and QALYs were 20,275 USD and 0.701 for Peg-G prophylaxis and 17,493 USD and 0.672 for no primary prophylaxis, respectively. The ICER was calculated to be 97,519 USD per QALY gained. The results were most sensitive to FN risk with Peg-G. When FN risk with no primary prophylaxis exceeded 51% or the cost of Peg-G was less than 649 USD per injection, the ICER was below the WTP threshold. The probabilistic analysis revealed a 9.1% probability that the ICER was below the WTP threshold. CONCLUSION Peg-G is not cost-effective in patients with NSCLC receiving RAM + DTX in Japan.

Abstract
Maintaining relative dose intensity (RDI) of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) improves the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). Pegfilgrastim was approved in Japan in November 2014 to prevent febrile neutropenia (FN) and maintain RDI.In this retrospective study, we reviewed 334 patients with DLBCL who received 6 or more courses of R-CHOP and analyzed the differences in the RDI, overall survival (OS), and progression-free survival between patients whose treatment started after November 2014 (postapproval group) and those whose treatment started before October 2014 (pre-approval group).The incidence of FN was lower (20% vs 38.3%, P < .001) and the RDI of R-CHOP was higher (86.8% vs 67.8%, P < .001) in the postapproval group. Pegfilgrastim was administered to many of these patients (76.8%) and was thought to have contributed to the high RDI maintenance in the postapproval group. Interrupted time-series analysis showed a significant rise of the RDI at the timing of pegfilgrastim approval in patients aged <70 years (estimated change: 18.1%, P < .001). The 5-year OS (85.7% vs 69.9%, P = .009) and progression-free survival (81.4% vs 64.4%, P = .011) were superior in the postapproval group. However, the differences were not significant in matched-pair analysis matching National Comprehensive Cancer Network-International Prognostic Index scores. Improved survival outcomes in this group were observed only among patients with Ann Arbor stage 3/4 (5-year OS: 83.7% vs 61.3%, P = .019) and high-risk on the National Comprehensive Cancer Network-International Prognostic Index (5-year OS: 80.7% vs 32.4%, P = .014). Multivariate analysis showed that a high RDI and low lactate dehydrogenase were associated with superior OS (RDI ≥ 85%, hazard ratio: 0.48, P = .016; lactate dehydrogenase > institutional upper limit of normal, hazard ratio: 2.38, P = .005).The RDI of R-CHOP was able to be maintained at higher levels, the incidence of FN was lower, and significantly better clinical outcomes were achieved in clinically high-risk groups after pegfilgrastim approval. Maintaining a high RDI in R-CHOP by administering pegfilgrastim to those who are likely to have low RDI without it is important for achieving favorable outcomes in patients with DLBCL.

Abstract
PURPOSE This study evaluated the efficacy, safety, and immunogenicity of biosimilar pegfilgrastim (PegFilBS) and originator pegfilgrastim (PegFilOR) in patients with stage 2-4 breast cancer. METHODS This phase III randomized, multicenter, evaluator-blinded, noninferiority study recruited women with stage 2-4 breast cancer in Argentina who were scheduled to receive chemotherapy. Stratification was based on the breast cancer stage. The primary end point was the duration of severe neutropenia (DSN, noninferiority margin: 1 day) in the first chemotherapy cycle. Secondary end points assessed were incidence of severe neutropenia, grade 3 neutropenia, febrile neutropenia, infections, postchemotherapy hospitalization and duration, and the incidence of adverse drug reactions (ADRs). RESULTS A total of 120 patients were randomly assigned to receive PegFilBS (58 patients) or PegFilOR (62 patients). Severe neutropenia occurred in 52 of 283 cycles (18.4%) for 27 patients who received PegFilBS and in 48 of 297 cycles (16.2%) for 20 patients who received PegFilOR (P = .48). During the first cycle, severe neutropenia occurred in 16 patients who received PegFilBS (DSN: 0.78 ± 1.53 days) and in 11 patients who received PegFilOR (DSN: 0.53 ± 1.25 days; 95% CI, -0.26 to 0.76 days). In the intention-to-treat analysis, the mean DSN values were 0.90 ± 1.79 days for the PegFilBS group and 0.50 ± 1.21 for the PegFilOR group (95% CI, -0.15 to 0.95 days). No significant differences were observed for the secondary efficacy end points. Three patients experienced seven ADRs in the PegFilBS group while 10 patients experienced 31 ADRs in the PegFilOR group. The most common ADR was myalgia. CONCLUSION Relative to PegFilOR, PegFilBS provided noninferior efficacy outcomes in Argentinian women with stage 2-4 breast cancer who were treated using myelosuppressive chemotherapy.

Abstract
BACKGROUND NYVEPRIA, a pegfilgrastim (a long-acting granulocyte colony-stimulating factor [G-CSF]) biosimilar, was recently recommended for marketing authorization in Europe for decreasing the incidence of febrile neutropenia (FN) in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs. The present study aimed to evaluate the financial impact of introducing a new pegfilgrastim biosimilar from a French healthcare system perspective. METHODS An Excel-based budget impact model was developed to estimate the financial impact by introducing a new pegfilgrastim biosimilar (NYVEPRIA) to France over a 5-year time horizon. Comparators included existing long-acting and short-acting G-CSFs. The burden of FN was obtained from existing literature. Costs (2021 Euros) included drug acquisition and administration, estimated based on drug dosage in both clinical trial and real-world settings. Scenario analyses were conducted to examine the robustness of key model assumptions. RESULTS In a total French population of 67.19 million, 79,873 patients were estimated to be treated with G-CSFs annually. The annual number of patients to be treated with NYVEPRIA was estimated to be 1593, 3195, 3674, 3782, and 4052 in years 1 to 5, respectively. Using real-world data, NYVEPRIA resulted in total annual cost savings of €8,620, €868,498, €868,498, €814,102, and €958,952 over years 1 to 5, respectively, leading to a cumulative 5-year cost savings of €3,518,669. Using data from clinical trials, NYVEPRIA resulted in total annual cost savings of €14,366, €1,447,496, €1,447,496, €1,356,836, and €1,598,253 over years 1 to 5, respectively, leading to a cumulative 5-year cost savings of €5,864,448. CONCLUSIONS The introduction of a new pegfilgrastim biosimilar (NYVEPRIA) is potentially associated with substantial cost savings for the French healthcare system.

Abstract
AIMS Therapeutic guidelines recommend prophylaxis against chemotherapy-induced (febrile) neutropenia (CIN/FN). Pegfilgrastim (Neulasta), biosimilar pegfilgrastim-jmdb (Fulphila), and pegfilgrastim with on-body injector (OBI; Neulasta Onpro) are options for CIN/FN prophylaxis. We aimed to simulate the cost-savings and budget-neutral expanded access to CIN/FN prophylaxis or anticancer treatment achieved through conversion from pegfilgrastim-OBI to pegfilgrastim-jmdb and to evaluate the economic impact of FN-related hospitalization costs due to pegfilgrastim-OBI failure. METHODS Cost-savings from conversion from pegfilgrastim-OBI to biosimilar pegfilgrastim-jmdb were simulated in a panel of 15,000 patients with cancer from the US payer perspective. The primary analyses included conversion rates of 10% to 100%. Adjusted analyses also considered OBI device failure rates of 1% to 7% and associated costs of FN-related hospitalization. Simulations of budget-neutral expanded access to prophylaxis with pegfilgrastim-jmdb or to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) for diffuse large B-cell lymphoma (DLBCL) were also performed. RESULTS In a 15,000-patient panel, conversion from pegfilgrastim-OBI to pegfilgrastim-jmdb resulted in cost-savings ranging from $481,259 (10% conversion) to $4,812,585 (100% conversion) in a single cycle. Over 6 cycles at 100% conversion, savings were $28,857,510 and could provide 9,191 additional doses of pegfilgrastim-jmdb or 4,463 cycles of R-CHOP to patients with DLBCL. Adjusted for OBI failure, cost-savings over 6 cycles ranged from $2,935,565 (10% conversion; pegfilgrastim-OBI failure rate of 1%) to $32,236,499 (100% conversion; 7% failure). These cost-savings could provide 943 doses of pegfilgrastim-jmdb or 454 doses of R-CHOP (10% conversion; 1% pegfilgrastim-OBI failure) or provide 10,261 doses of pegfilgrastim-jmdb or 4,982 cycles of R-CHOP (100% conversion; 7% failure). CONCLUSION Conversion from pegfilgrastim to pegfilgrastim-jmdb is associated with significant cost-savings which increase markedly when also accounting for pegfilgrastim-OBI failure and associated FN-related hospitalizations. These general and failure-related cost-savings could be allocated on a budget-neutral basis to provide more patients with additional CIN/FN prophylaxis or antineoplastic treatment.

Abstract
AIMS In this pharmacoeconomic simulation, we: (1) modeled the cost-efficiency of converting patients from reference pegfilgrastim to biosimilar pegfilgrastim-cbqv for prophylaxis of chemotherapy-induced (febrile) neutropenia (CIN/FN) from the US payer perspective, (2) simulated how savings enable, on a budget-neutral basis, expanded access to pegfilgrastim-cbqv, and (3) estimated the number-needed-to-convert (NNC) to purchase one additional dose of pegfilgrastim-cbqv. METHODS In a hypothetical panel of 20,000 patients, we modeled cost-savings utilizing: two reference formulations (pre-filled syringe [PFS] and on-body injector [OBI]), three medication cost inputs (average sales price [ASP], wholesale acquisition cost [WAC], and an age-proportionate blended ASP/WAC rate), administration cost for injection (PFS) and device application (OBI), conversion rates of 10-100%, and 1-6 cycles of prophylaxis. Cost-savings were used to estimate additional doses of pegfilgrastim-cbqv that could be purchased and the NNC to purchase one additional dose. RESULTS Using ASP and 10% conversion from reference OBI to pegfilgrastim-cbqv, savings range from $326,744 (1 cycle) to $2.0M (6 cycles) which could provide 93-556 additional doses of pegfilgrastim-cbqv, respectively; the NNC to purchase one additional dose of pegfilgrastim-cbqv ranges from 21.6 (1 cycle) down to 3.6 patients (6 cycles). The WAC model saves $41.1M per cycle and $246.7M over 6 cycles at 100% conversion from reference PFS which could provide 9,709-58,253 additional pegfilgrastim-cbqv doses; the NNC ranges from 2.1 (1 cycle) to 0.3 (6 cycles). Using the blended ASP/WAC rate, converting 50% from reference OBI to pegfilgrastim-cbqv would save $10.2M per cycle and $60.9M over 6 cycles providing 2,638-15,829 additional doses of pegfilgrastim-cbqv; NNCs are 3.8 (1 cycle) and 0.6 patients (6 cycles). CONCLUSIONS Converting 20,000 patients from reference to pegfilgrastim-cbqv over 6 cycles can generate savings up to $246.7M, enough to purchase up to 58,253 additional doses of pegfilgrastim-cbqv. This simulation provides economic justification for prophylaxis with biosimilar pegfilgrastim-cbqv.

Abstract
INTRODUCTION Pegfilgrastim-cbqv was developed as a biosimilar of pegfilgrastim, a pegylated form of recombinant human granulocyte colony-stimulating factor approved for decreasing febrile neutropenia-associated infection in patients receiving myelosuppressive drugs. This multicenter, randomized, single-blind, partial-reference-replicated, three-sequence crossover study assessed pharmacokinetic and pharmacodynamic bioequivalence of pegfilgrastim-cbqv and pegfilgrastim in healthy subjects. METHODS One hundred twenty-two subjects were randomized to one of three treatment sequences; each included one dose of pegfilgrastim-cbqv and two doses of pegfilgrastim separated by ≥ 28 days. The primary pharmacokinetic end points were area under the curve (AUC) from 0 to infinity (AUC0-∞) and maximum concentration (Cmax). The primary pharmacodynamic end points were maximum absolute neutrophil count (ANCmax) and ANC AUC from time 0 to the last measurable observation (ANC AUC0-last). Pharmacokinetic and pharmacodynamic bioequivalences were demonstrated if the 90% CI for the geometric mean ratio (GMR) of pegfilgrastim-cbqv to pegfilgrastim was within 80-125% for the primary end points. RESULTS Pharmacokinetic bioequivalence criteria were met for Cmax (GMR 105.0; 90% CI 95.5-115.4) and AUC0-∞ (GMR 97.5; 90% CI 88.6-107.2). Pharmacodynamic bioequivalence criteria were met for ANCmax (GMR 99.6; 90% CI 96.2-103.2) and ANC AUC0-last (GMR 96.7; 90% CI 92.2-101.4). Adverse events occurred in 76.0%, 76.6%, and 73.1% of subjects for pegfilgrastim-cbqv, first pegfilgrastim, and second pegfilgrastim dosing periods across treatment sequences, respectively. Investigators found no drug-related serious adverse events. CONCLUSION This study established pharmacokinetic and pharmacodynamic bioequivalence of pegfilgrastim-cbqv to pegfilgrastim. The treatments displayed similar safety profiles, including immunogenicity, with no unexpected safety findings. CLINICAL TRIALS REGISTRATION ClinicalTrials.gov, NCT02650973, February 2016.

Abstract
Biologic drugs represent a large and growing portion of health expenditures. Increasing the use of biosimilars is a promising option for controlling spending growth in pharmaceutical care. Amid the considerable uncertainty concerning physicians’ decision to prescribe biosimilars, explicit cost control measures may help increase biosimilar use. We analyze the role of regional cost control measures for biosimilars and their association with physician prescriptions in ambulatory care in Germany. We collect data on cost control measures implemented by German physician associations and national claims data on statutory health insurance covering 2009 to 2015. We perform panel regressions that include time and physician fixed effects to identify the average associations between cost control measures and biosimilar share/use while controlling for unobserved physician heterogeneity, patient structure, and socioeconomic factors. We identify 44 measures (priority prescribing, biosimilar quota) for erythropoiesis-stimulating substances, filgrastim, and somatropin. Estimates of cost control measures and their consequences for biosimilar share and use are heterogeneous by drug, measure type, and physician group. Across specialists, biosimilar quotas accounted for 5.13% to 9.75% of the total average biosimilar share of erythropoiesis-stimulating substances. Explicit quota regulations are more effective than priority prescribing. Regional variation in biosimilar use can be partly attributed to the presence of cost control measures.

Abstract
BACKGROUND Pegfilgrastim, a long-acting granulocyte-colony-stimulating factor(G-CSF), has been used as prophylaxis for severe hematotoxicity induced by chemotherapy. We report a case of aortitis induced by pegfilgrastim administration during modified FOLFIRINOX(mFOLFIRINOX)chemotherapy for metastatic pancreatic cancer. CASE REPORT A 65-year-old woman underwent a distal pancreatectomy for pancreatic tail cancer. Liver metastases appeared 2 years after the surgery. mFOLFIRINOX chemotherapy was started with prophylactic administration of pegfilgrastim. Eight days after the first administration and 6 days after administration of the 8th course, the patient developed a fever. The blood test results indicated severe inflammation. Computed tomography revealed a thickened aorta indicating aortitis. The symptoms rapidly improved with antibiotic therapy. We diagnosed aortitis induced by pegfilgrastim administration. CONCLUSION Aortitis should be considered when a patient has unidentified inflammatory findings after receiving pegfilgrastim.

Abstract
Docetaxel(DTX)plus ramucirumab(RAM)therapy is recommended as second-line or later treatment by the Japanese lung cancer guideline. However, febrile neutropenia(FN)is a frequent complication with this therapy. Efforts for reducing FN risk are essential. We administered pegfilgrastim, a durable granulocyte colony-stimulating factor, as primary prophylaxis for FN to all patients. We also reduced the dose of DTX according to its toxicity. Moreover, we used RAM monotherapy. Herein, we report the results of these efforts regarding DTX plus RAM therapy. We retrospectively reviewed the therapeutic results and occurrence of various adverse effects in 11 patients who started receiving DTX plus RAM therapy in our department between August 2016 and December 2017. Median number of DTX plus RAM cycles was 8(1-25). The following best effects were noted: 2(18%)patients, complete response: 5(45%), partial response: 2(18%), stable disease: and 2(18%), nonevaluable. No patient showed progressive disease. The overall response rate was 63.6%, and the disease control rate was 81.8%. Median progression-free survival was 127 days, and the 1-year progression-free survival rate was 27.3%. The median overall survival duration was not reached, and the 1-year overall survival rate was 53.0%. Adverse effects higher than Grade 3 occurred in 2 cases. FN was not observed. By using pegfilgrastim as primary prophylaxis, we could suppress FN onset in patients; furthermore, we observed better overall response and disease control rates than those observed in clinical trials.

Abstract
The present study reports the case of a 45-year-old pre-menopausal woman treated with 6courses of TAC chemotherapy by the pegfilgrastim for preoperative chemotherapy. The patient visited our hospital in February 2010 with the chief complaint of a mass in the right breast. A 40mm tumor in the outer lower area of the right breast and the axillary lymph nodes was palpable. Pathological findings revealed scirrhous carcinoma with an ER(+), PgR(+), HER2(1+), and Ki-67 80%profile. Pre-operatively, the patient underwent 6courses of triweekly TAC(docetaxel[75mg/m / 2], adriamycin[50mg/m2], cyclo- phosphamide[500mg/m2])chemotherapy. Pegfilgrastim(3.6m g)was subcutaneously injected on the next day of each course. The side effect of 6courses of TAC was stomatitis and low back pain(Grade 2). Relative dose intensity(RDI)was not reduced and there was no occurrence of febrile neutropenia(FN). Partial resection of the tumor was facilitated. Pathologically viable tumor cells still lay scattered in the range of 45 mm, and a ductal carcinoma in situ was seen. However, metastasis to axillary lymph nodes was not observed. Radiation therapy(50 Gy)was performed on the residual breast. There was no recurrence, and now she survival free with tamoxifen(20mg/day)of 8 years four months after operation. TAC with pegfilgrastim therapy could be an effective pre-operative chemotherapy regimen in breast cancer.

Abstract
Background The aim of the study was to evaluate the role and potential benefit of granulocyte colony-stimulating factor (G-CSF, Filgrastim), administered following cytotoxic chemotherapy with the ABVD regimen in Hodgkin's disease, in maintaining cycle schedule and dose intensity and in decreasing neutropenia and number of infections. Patients and Methods Twenty-two patients affected by high-risk Hodgkin's disease (14 localized and 8 diffuse), aged 15 to 69 years (median, 34), were given ABVD chemotherapy for a total of 6 courses (for the purpose of this study, each single course of chemotherapy was considered as two 15-day periods). No patient was given G-CSF after the first cycle. After each cycle, G-CSF was administered only for: 1) absolute neutrophil count < 1 × 109/L between cycles; 2) delay in cycle schedule due to an absolute neutrophil count < 1 × 109/L on the planned day of treatment; or 3) fever or a documented infection, regardless the absolute neutrophil count. Once administered, G-CSF was maintained in the subsequent cycles. Results Seventeen of 22 patients (77%) required the administration of G-CSF (5 μg/kg b.w.; a median of 5 doses/cycle); most of them (13/17) before the 5th dose of chemotherapy. The main reason for introducing G-CSF into therapy was neutropenia during the interval between courses (n = 4) or on the planned day of treatment (n = 11). Comparing 112 courses where G-CSF was not administered with 124 where it was, in the latter group we observed: 1) a significantly lower (P = 0.0002) incidence of cycle delays (0 vs 13), with a median delay of 7 days (5 to 11). The main reason for cycle delay was neutropenia (n = 13); 2) a greater dose intensity delivered to the patients while on G-CSF (100% vs 95.2±8.8%; P = 0.0001); 3) an absolute neutrophil count significantly higher at day 8 (P<0.0001) and day 15 (P< 0.0001); 4) a significantly lower (P = 0.0003) incidence of neutropenia (2 vs. 17). No difference in the incidence of infections was observed between the two groups of cycles (P = 0.5889), but the duration and severity of the same were greater during chemotherapy without G-CSF, requiring antibiotic therapy and causing cycle delay. Conclusions In conclusion, our data suggest the use of Filgrastim in Hodgkin's disease also during conventional-dose chemotherapy with ABVD. It is not required from the first dose of therapy, but as soon as neutropenia appears between cycles or on the planned day of treatment. Then, its use allows maintenance of the chemotherapy schedule and dose intensity. It also decreases frequency, duration and severity of neutropenia and its sequelae.

Abstract
Aims and background Dose intensification of chemotherapy is associated with increased response rates in advanced breast cancer. Achievement of dose incrementation is usually limited by drug-dependent bone marrow toxicity. The recent availability of recombinant human colony-stimulating factors (CSFs) have made it possibile to evaluate their potential in ameliorating chemoterapy-induced myelosuppression. The aim of this study was to evaluate tolerability and effectiveness of an intensified mitoxantrone, methotrexate and mitomycin-C (3M) regimen, given with G-CSF support in patients with advanced breast cancer (ABC). Study design Twenty-eight eligible patients with advanced breast cancer were treated with mitomycin -C (7 mg/sqm iv every 4 weeks), methotrexate (35 mg/sqm iv) and mitoxantrone (7 mg/sqm iv every 2 weeks) for 6 cycles. Recombinant human granulocyte colony-stimulating factor (r-HuG-CSF, Filgrastim) (5 μg/kg/day) was given subcutaneously from day 2 to day 12 after each chemotherapy administration to prevent leukopenia. Results Of the 27 evaluable patients, 4 had complete response and 14 achieved partial response; the overall response rate was 63% (95% Cl; 46.8%-82.2%). The median duration of response was 8 months (range, 4-13+). Chemotherapy-related toxicity was mild: only 3 out of 163 courses had to be postponed due to myelotoxicity. Conclusions The 3M regimen given at 2- week intervals is a feasible, active and well toleratel treatment in patients not previously treated for metastatic breast cancer.

Abstract
Aims and background The study was performed to assess the feasibility and activity of an intensive chemotherapeutic regimen as adjuvant treatment for patients with resected gastric cancer at high risk of recurrence (PT2N1-2; pT3-4Nany M0). Patients and methods Starting 21 to 28 days after potentially curative surgery for primary gastric cancer, 25 patients received 8 weekly cycles of cisplatin 40 mg/m2, 5-fluorouracil 500 mg/m2, epidoxorubicin 35 mg/m2, 6S-stereoisomer of leucovorin at a dose of 250 mg/m2, and glutathione at a dose of 1.5 g/m2. From the day after to the day before each cycle of chemotherapy, filgrastim was administered by subcutaneous injection at a dose of 5 μg/kg. Results After a median follow-up of 33 months, 80% of the patients were alive and disease-free. Five patients had relapsed: three in the liver, one in the peritoneum and one in the lymph nodes. Toxicity was mild: five patients experienced WHO grade III toxicity (three leukopenia, two thrombocytopenia); no toxic deaths occurred. Conclusion Intensive weekly chemotherapy is a feasible postoperative treatment option for patients with resected gastric cancer at high risk of relapse. These data, together with recent results in advanced disease, make this approach of interest for the development of new programs of adjuvant therapy in this setting.

Abstract
Filgrastim is usually combined with chemotherapy to mobilize hematopoietic progenitor cells in non-Hodgkin lymphoma (NHL) patients. Limited information is available on the efficacy of a preemptive plerixafor (PLER) injection in poor mobilizers after chemotherapy and pegfilgrastim. In this prospective study, 72 patients with NHL received chemotherapy plus pegfilgrastim, and 25 hard-to-mobilize patients received also PLER. The usefulness and efficacy of our previously developed algorithm for PLER use in pegfilgrastim-containing mobilization regimen were evaluated as well as the graft cellular composition, hematological recovery, and outcome after autologous stem cell transplantation (auto-SCT) according to the PLER use. A median 3.4-fold increase in blood CD34+ cell counts was achieved after the first PLER dose. The minimum collection target was achieved in the first mobilization attempt in 66/72 patients (92%) and 68 patients (94%) proceeded to auto-SCT. An algorithm for PLER use was fulfilled in 76% of the poor mobilizers. Absolute numbers of T-lymphocytes and NK cells were significantly higher in the PLER group, whereas the number of CD34+ cells collected was significantly lower. Early neutrophil engraftment was slower in the PLER group, otherwise hematological recovery was comparable within 12 months from auto-SCT. No difference was observed in survival according to the PLER use. Chemotherapy plus pegfilgrastim combined with preemptive PLER injection is an effective and convenient approach to minimize collection failures in NHL patients intended for auto-SCT. A significant effect of PLER on the graft cellular composition was observed, but no difference in outcome after auto-SCT was detected.

Abstract
BACKGROUND Adjuvant chemotherapy for early breast cancer has improved outcomes but causes toxicity. The UK TACT2 trial used a 2×2 factorial design to test two hypotheses: whether use of accelerated epirubicin would improve time to tumour recurrence (TTR); and whether use of oral capecitabine instead of cyclophosphamide would be non-inferior in terms of patients' outcomes and would improve toxicity, quality of life, or both. METHODS In this multicentre, phase 3, randomised, controlled trial, we enrolled patients aged 18 years or older from 129 UK centres who had histologically confirmed node-positive or high-risk node-negative operable breast cancer, had undergone complete excision, and were due to receive adjuvant chemotherapy. Patients were randomly assigned to receive four cycles of 100 mg/m2 epirubicin either every 3 weeks (standard epirubicin) or every 2 weeks with 6 mg pegfilgrastim on day 2 of each cycle (accelerated epirubicin), followed by four 4-week cycles of either classic cyclophosphamide, methotrexate, and fluorouracil (CMF; 600 mg/m2 cyclophosphamide intravenously on days 1 and 8 or 100 mg/m2 orally on days 1-14; 40 mg/m2 methotrexate intravenously on days 1 and 8; and 600 mg/m2 fluorouracil intravenously on days 1 and 8 of each cycle) or four 3-week cycles of 2500 mg/m2 capecitabine (1250 mg/m2 given twice daily on days 1-14 of each cycle). The randomisation schedule was computer generated in random permuted blocks, stratified by centre, number of nodes involved (none vs one to three vs four or more), age (≤50 years vs >50 years), and planned endocrine treatment (yes vs no). The primary endpoint was TTR, defined as time from randomisation to first invasive relapse or breast cancer death, with intention-to-treat analysis of standard versus accelerated epirubicin and per-protocol analysis of CMF versus capecitabine. This trial is registered with ISRCTN, number 68068041, and with ClinicalTrials.gov, number NCT00301925. FINDINGS From Dec 16, 2005, to Dec 5, 2008, 4391 patients (4371 women and 20 men) were recruited. At a median follow-up of 85·6 months (IQR 80·6-95·9) no significant difference was seen in the proportions of patients free from TTR events between the accelerated and standard epirubicin groups (overall hazard ratio [HR] 0·94, 95% CI 0·81-1·09; stratified p=0·42). At 5 years, 85·9% (95% CI 84·3-87·3) of patients receiving standard epirubicin and 87·1% (85·6-88·4) of those receiving accelerated epirubicin were free from TTR events. 4358 patients were included in the per-protocol analysis, and no difference was seen in the proportions of patients free from TTR events between the CMF and capecitabine groups (HR 0·98, 95% CI 0·85-1.14; stratified p=0·00092 for non-inferiority). Compared with baseline, significantly more patients taking CMF than those taking capecitabine had clinically relevant worsening of quality of life at end of treatment (255 [58%] of 441 vs 235 [50%] of 475; p=0·011) and at 12 months (114 [34%] of 334 vs 89 [22%] of 401; p<0·001 at 12 months) and had worse quality of life over time (p<0·0001). Detailed toxicity and quality-of-life data were collected from 2115 (48%) of treated patients. The most common grade 3 or higher adverse events in cycles 1-4 were neutropenia (175 [16%]) and fatigue (56 [5%]) of the 1070 patients treated with standard epirubicin, and fatigue (63 [6%]) and infection (34 [3%]) of the 1045 patients treated with accelerated epirubicin. In cycles 5-8, the most common grade 3 or higher adverse events were neutropenia (321 [31%]) and fatigue (109 [11%]) in the patients treated with CMF, and hand-foot syndrome (129 [12%]) and diarrhoea (67 [6%]) in the 1044 patients treated with capcitabine. INTERPRETATION We found no benefit from increasing the dose density of the anthracycline component of chemotherapy. However, capecitabine could be used in place of CMF without significant loss of efficacy and with improved quality of life. FUNDING Cancer Research UK, Amgen, Pfizer, and Roche.

Abstract
The higher order structure (HOS) of biotherapeutics is a critical quality attribute that can be evaluated by nuclear magnetic resonance (NMR) spectroscopy at atomic resolution. NMR spectral mapping of HOS can be used to establish HOS consistency of a biologic across manufacturing changes or to compare a biosimilar to an innovator reference product. A previous inter-laboratory study performed using filgrastim drug products demonstrated that two-dimensional (2D)-NMR 1HN-15NH heteronuclear correlation spectroscopy is a highly robust and precise method for mapping the HOS of biologic drugs at natural abundance using high sensitivity NMR 'cold probes.' Here, the applicability of the 2D-NMR method to fingerprint the HOS of filgrastim products is demonstrated using lower sensitivity, room temperature NMR probes. Combined chemical shift deviation and principal component analysis are used to illustrate the performance and inter-laboratory precision of the 2D-NMR method when implemented on room temperature probes.

Abstract
Febrile neutropenia(FN)is one of the serious treatment-related toxicities after FEC100(5-fluorouracil 500mg/m2, epiru- bicin 100mg/m2, cyclophosphamide 500 mg/m2)chemotherapy for breast cancer. Granulocyte-colony stimulating factor(GCSF) is used as a support therapy for FN. Thus, we evaluated retrospectively the safety of administering pegfilgrastim the day after FEC100 chemotherapy in Japanese patients with breast cancer as compared with lenograstim. Grade 3 or 4 neutropenia was observed in 91.7% patients after pegfilgrastim administration and in 63.2% after lenograstim. The incidence rate of FN was 7.0%after pegfilgrastim administration and 9.7%after lenograstim, a difference that was not significantly different(p= 0.741). The mean relative dose intensity was good at 0.98 for pegfilgrastim and 0.97 for lenograstim. In conclusion, pegfilgrastim is not inferior to lenograstim in the incidence of FN. However, we do not recommend administering pegfilgrastim on the day after FEC100 therapy because it causes more severe neutropenia and has a high risk of FN. The timing of administration of pegfilgrastim in FEC100 therapy requires further study.

Abstract
OBJECTIVE The pegfilgrastim on-body injector (OBI) is a single-use, disposable, battery-powered injector that is designed to automatically deliver a single subcutaneous dose of pegfilgrastim beginning approximately 27 hours after activation and continuing over approximately 45 minutes. In this open-label study, we assessed performance of the OBI delivering placebo buffer in healthy volunteers. RESEARCH DESIGN AND METHODS Healthy men and women aged 18-55 years, with a body mass index of 18-35 kg/m2, were enrolled. OBIs were activated by filling them with placebo buffer, and two injectors were applied concurrently to each subject: one to the abdomen and one to the back of the upper arm. Subjects were monitored for substantial leakage during and after administration. MAIN OUTCOME MEASURES The primary endpoint of the study was successful delivery of placebo buffer based on a composite of the following: no substantial leakage during or after administration, green status light indicator on the injector during and after administration, and fill indicator bar at the empty position after administration. The secondary endpoint was the incidence of treatment-emergent adverse events (AEs). RESULTS Of the 150 subjects enrolled, 149 (99.3%) completed the study. Study subjects were 48.0% men, and 52.0% women; 47.3% were white, 35.3% black or African American, 12.7% Asian, and 4.7% other. Mean (SD) age was 35.9 (10.8) years. Of the 297 total deliveries, 292 (98.3%) were considered successful: 147/149 (98.7%; 95% confidence interval [CI]: 95.2%-99.6%) to the abdomen and 145/148 (98.0%; 95% CI: 94.2%-99.3%) to the back of the upper arm. Five deliveries were considered unsuccessful: two due to hazard alarms, and three due to substantial leakage. The most common treatment-emergent AEs (in >2% of subjects overall) by preferred term were medical device site reaction (20.7%), catheter-site hemorrhage (8.7%), and headache (3.3%). No serious AEs were reported. CONCLUSIONS The pegfilgrastim OBI was well tolerated, and deliveries of placebo buffer were successful 98.3% of the time. The generalizability of these results may be limited by the conduct of this study in healthy subjects in a controlled environment.

Abstract
Objective: To review the hematologic adverse effects of hepatitis C virus (HCV) therapy and adjuvant treatment with epoetin alfa and granulocyte colony-stimulating factor (ie, filgrastim). Data Sources: Medical literature indexed in MEDLINE (1966–January 2007) and EMBASE (1980–January 2007) was searched, and published conference abstracts were reviewed. Study Selection and Data Extraction: Peer-reviewed articles and relevant conference abstracts regarding the use of epoetin alfa and granulocyte colony-stimulating factor were reviewed. Data Synthesis: Ribavirin induces a dose-dependent hemolytic anemia. Studies using epoetin alfa 40 000 units subcutaneously once weekly have demonstrated efficacy in maintaining hemoglobin, ribavirin dose, and quality of life scores, but clear benefit shown with sustained virologic response (SVR) is lacking. The hemoglobin threshold for initiation of epoetin alfa used in studies may not adequately reflect values used in clinical practice. Treatment-related neutropenia is caused primarily by interferon or peg interferon. Few studies have investigated the impact of granulocyte or granulocyte-macrophage colony-stimulating factor derivatives on neutropenia. Results of dose maintenance evaluation vary, and studies reporting data on SVR showed no effect from growth factor therapy. The frequency of bacterial infections was not reported. Conclusions: The role and benefit of hematopoietic growth factors in HCV therapy have not been conclusively determined to date. However, the possibility of a benefit to individual patients seen on an outpatient basis remains, and an individualized treatment approach is recommended.

Abstract
Objective: To report a pediatric case of pegfilgrastim-induced hyperleukocytosis. Case Summary: A 3-year-old boy with medulloblastoma therapy presented with white blood cell (WBC) count 0.1 × 103/μL and absolute neutrophil count (ANC) 0.014 × 103/μL on day 27 following a course of induction chemotherapy. The patient received pegfilgrastim 200 μg/kg the following day. On his return 6 days later for the next planned course of chemotherapy, hyperleukocytosis was determined, with WBC 149 × 103/μL and ANC 110 × 103/μL (“neutrophil overshoot”). No sources of the elevated WBC count other than administration of pegfilgrastim (eg, steroids, antiepileptics, infection) were present. Chemotherapy was delayed until the WBC count had fallen to 35.2 × 103/μL (ANC 28.9 × 103/μL). No sequelae from this adverse effect occurred. Discussion: Pegfilgrastim has unique saturable neutrophil receptor-mediated clearance, the ability for self-regulation. Due to this clearance mechanism, hyperleukocytosis associated with pegfilgrastim use is uncommon in adults and has not been previously reported in pediatrics. The pegfilgrastim dose in children is under investigation; however, 100–110 μg/kg has been effective and safe in this population. Use of the Naranjo probability scale suggested that pegfilgrastim was the probable cause of hyperleukocytosis in our patient. Conclusions: Pegfilgrastim 200 μg/kg, in excess of the 100 μg/kg dose used in limited pediatric clinical trials, appeared to exceed saturable neutrophil receptor-mediated clearance. The inability of this mechanism to self-regulate neutrophil counts in the normal range led to neutrophil overshoot. Routine pediatric use of the pegylated dosage form of G-CSF should await further published clinical trials to validate a safe and effective dose.

Abstract
FOLFIRINOX therapy has a high response rate for pancreatic carcinoma, but has serious adverse effects. FOLFIRINOX therapy was administered to 11 patients with locally advanced pancreatic carcinoma at our hospital. We investigated the usefulness of primary prophylactic administration of pegfilgrastim(PegG). In the group receiving PegG, as well as with onset of neutropenia and thrombocytopenia, febrile neutropenia was reduced. Rates of anorexia and fatigue were also lower than in those who did not receive PegG. The PegG group maintained a high average relative dose intensity, as well as a high response rate. Primary prophylactic administration of PegG in FOLFIRINOX therapy is valid for pancreatic carcinoma.

Abstract
We assessed the incidence of febrile neutropenia(FN), infection, and relative dose intensity(RDI)with or without the use of pegfilgrastim in breast cancer patients receiving adjuvant or neoadjuvant chemotherapy. Twenty-five patients received 4 cycles of FEC(5-FU 500mg/m2 plus epirubicin 100 mg/m2 plus cyclophosphamide 100 mg/m2 q3w)followed by 4 cycles of docetaxel(75mg/m2 q3w). Ten patients were administered pegfilgrastim as primary prophylaxis throughout all cycles of chemotherapy, and 15 patients were not. The rate of FN was only 7% in patients not undergoing pegfilgrastim therapy. The infection rate and RDI were not significantly different between the 2 groups, but the incidence of fever was lower in patients treated with pegfilgrastim. In patients with early stage breast cancer, the use of primary pegfilgrastim during all chemotherapy cycles should be considered a safe option.

Abstract
BACKGROUND Intractable bone pain is a notorious adverse effect of granulocyte-colony stimulating factors (G-CSFs), such as pegfilgrastim and filgrastim, which are given to help prevent neutropenia in patients who are undergoing chemotherapy. G-CSF-induced bone pain is surprisingly common and often refractory to treatment with conventional analgesics. CASE REPORT This article describes an emergency department case of opiate and nonsteroidal anti-inflammatory drug-resistant pegfilgrastim-induced bone pain that was successfully alleviated with 10 mg of oral loratadine, allowing for discharge home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case suggests that loratadine may be an easy to implement, safe, and effective therapy in the emergency department management of intractable bone pain caused by G-CSF use. Emergency physicians should be aware that loratadine may successfully relieve otherwise intractable G-CSF-induced bone pain and allow for discharge home.

Abstract
BACKGROUND This retrospective study aimed to evaluate the efficacy of a 3.6-mg dose of pegfilgrastim for primary prophylaxis in Japanese breast cancer patients receiving dose-dense chemotherapy. METHODS Patients treated with adjuvant or neoadjuvant chemotherapy for early-stage breast cancer at the Tokyo-West Tokushukai Hospital were included in this analysis. Because 6 mg pegfilgrastim has not yet been approved for use in Japan, we compared the outcomes of a dose-dense doxorubicin and cyclophosphamide regimen plus 3.6 mg pegfilgrastim support with a conventional dose epirubicin and cyclophosphamide regimen. The incidence of febrile neutropenia, relative dose intensity, dose delay, dose reduction, regimen change and hospitalization because of neutropenia were assessed. RESULTS From November 2013 to March 2016, 97 patients with stage I-III invasive breast cancer were analyzed (dose-dense doxorubicin and cyclophosphamide plus 3.6-mg pegfilgrastim group, n = 41; epirubicin and cyclophosphamide group, n = 56; median ages, 49.0 and 48.5 years, respectively). Febrile neutropenia occurred during the first chemotherapy cycle in 7 of 56 patients (12.5%) in the epirubicin and cyclophosphamide group and 0 of 41 patients in the dose-dense doxorubicin and cyclophosphamide group (P = 0.02). The average relative dose intensities were 97.9% and 96.8%, respectively (P = 0.28), with corresponding dose delay rates of 4.9% (2/41) and 16.1% (9/56), respectively (P = 0.11) and dose reduction rates of 0% (0/41) and 7.1% (4/56), respectively (P = 0.16). CONCLUSIONS Our results indicate the efficacy of a 3.6-mg pegfilgrastim dose for the primary prevention of febrile neutropenia in dose-dense doxorubicin- and cyclophosphamide-treated Japanese breast cancer patients.

Abstract
BACKGROUND More than 20%of breast cancer patients who undergo myelosuppressive chemotherapy involving FEC(100) or TC experience febrile neutropenia(FN), and pegfilgrastim is commonly recommended as the primary prophylaxis. Delays and/or dose-reductions in chemotherapy should be avoided as much as possible to maximize the clinical benefits of these adjuvant chemotherapies. PURPOSE This study assessed the relative dose intensity(RDI), efficacy, and safety of pegfilgrastim in patients with breast cancer. The incidence of FN was also evaluated. METHODS Twenty-six patients with breast cancer undergoing FEC(100)or TC were included in this retrospective study. RESULTS Of the 26 patients, 19 patients who underwent FEC(100)and 7 patients who underwent TC received 3.6 mg of pegfilgrastim 24 hours after administration of the myelosuppressive chemotherapy. Four and 14 patients who underwent FEC(100)achieved 85-99% and 100% RDI, respectively. All 7 patients who underwent TC achieved 100% RDI. Grade 3 and 4 adverse events, as assessed using the CTCAE, were observed in 11 patients who underwent FEC(100): 2 patients experienced leukocytopenia, 7 experienced neutropenia, 1 experienced thrombocytopenia, and 1 experienced FN. Four patients who underwent TC experienced Grade 3 and 4 adverse events: 1 patient each experienced bone pain, neutropenia, anemia, and FN. CONCLUSIONS Pegfilgrastim can reduce the incidence of FN and maintain RDI in patients with breast cancer undergoing myelosuppressive chemotherapy.

Abstract
Recently, newer agents in regimens such as FOLFIRINOX have shown promising activity, being superior to gemcitabine as a single agent for unresectable pancreatic cancer patients with good performance status. Herein, we report a case of pancreatic cancer treated with the FOLFIRINOX regimen and pegfilgrastim prophylaxis as second-line treatment in a patient who failed this regimen. He previously received gemcitabine/nab-paclitaxel combination chemotherapy as first-line treatment. It was reported that grade 3-4 neutropenia frequently occurred in many patients receiving the FOLFIRINOX regimen. Prophylactic use of pegfilgrastim is recommended for cancer patients who are at high risk of neutropenic events. However, severe neutropenia occurred with the FOLFIRINOX regimen in spite of pegfilgrastim prophylaxis. We emphasize the importance of occasional serious adverse effects with the FOLFIRINOX regimen and pegfilgrastim prophylaxis.

Abstract
AIM This randomized, double-blind trial compared proposed biosimilar LA-EP2006 with reference pegfilgrastim in women receiving chemotherapy for breast cancer (PROTECT-1). PATIENTS & METHODS Women (≥18 years) were randomized to receive LA-EP2006 (n = 159) or reference (n = 157) pegfilgrastim (Neulasta(®), Amgen) for ≤6 cycles of (neo)-adjuvant TAC chemotherapy. Primary end point was duration of severe neutropenia (DSN) during cycle 1 (number of consecutive days with absolute neutrophil count <0.5 × 10(9)/l) with equivalence confirmed if 90% and 95% CIs were within a ±1 day margin. RESULTS For DSN, LA-EP2006 was equivalent to reference (difference: 0.07 days; 90% CI: -0.09-0.23; 95% CI: -0.12-0.26). CONCLUSION LA-EP2006 and reference pegfilgrastim showed no clinically meaningful differences regarding efficacy and safety in breast cancer patients receiving chemotherapy.

Abstract
BACKGROUND/AIMS Rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 14 days seems to achieve better outcomes than R-CHOP every 21 days in diffuse large B-cell lymphoma (DLBCL) patients. Currently, the standard regimen is R-CHOP every 21 days. METHODS This is a phase II clinical trial of treatment with 6 cycles of R-CHOP-14 with pegfilgrastim support in 2 populations of previously untreated DLBCL patients aged ≥65 years (n = 73) or <65 years (n = 51) with low-risk International Prognostic Index scores (0-2). RESULTS With a median follow-up of 63.7 months, the 5-year event-free survival rate was 53.8% in patients aged ≥65 years and 71.0% in patients aged <65 years. The 5-year overall survival rate was 71.4 and 89.8%, respectively. The complete remission rate was 69.9% for older and 80.4% for younger patients. The median relative dose intensity of cytotoxic drugs was 143.2% in the elderly and 149.1% in the young patients. Febrile neutropenia was the most common grade 3-4 adverse event, being higher in elderly patients (21.3 vs. 9.3%). Eight deaths (7 in elderly patients) were considered treatment related. CONCLUSION In conclusion, the R-CHOP-14 regimen is feasible and very active, though it is more toxic in elderly patients mainly due to an increased incidence of infections. New strategies, such as new monoclonal antibodies or new targeted therapies, are needed to improve the outcomes of DLBCL patients.

Abstract
BACKGROUND Pegfilgrastim is widely used for the prevention of chemotherapy-induced neutropenia. In highly regulated markets, there are currently no approved biosimilars of pegfilgrastim. Pegfilgrastim Randomized Oncology (Supportive Care) Trial to Evaluate Comparative Treatment (PROTECT-2) was a confirmatory efficacy and safety study designed to compare proposed biosimilar LA-EP2006 with reference pegfilgrastim (Neulasta, Amgen) in early-stage breast cancer patients receiving adjuvant or neoadjuvant myelosuppressive chemotherapy. METHODS A total of 308 patients were randomized to LA-EP2006 or reference pegfilgrastim. Each patient received TAC (intravenous docetaxel 75 mg/m(2), doxorubicin 50 mg/m(2), and cyclophosphamide 500 mg/m(2)) on day 1 of each cycle, for six or more cycles. Pegfilgrastim (LA-EP2006 or reference) was given subcutaneously (6 mg in 0.6 mL) on day 2 of each cycle. The primary endpoint was duration of severe neutropenia (DSN) during cycle 1 (number of consecutive days with an absolute neutrophil count <0.5 × 10(9)/L), with equivalence confirmed if 90% and 95% confidence intervals (CIs) were within a 1-day margin. RESULTS Baseline characteristics were well balanced. DSN was equivalent between groups at mean ± SD 1.36 ± 1.13 (LA-EP2006, n = 155) and 1.19 ± 0.98 (reference, n = 153) in cycle 1. With a treatment difference (reference minus LA-EP2006) of -0.16 days (90% CI -0.36 to 0.04; 95% CI -0.40 to 0.08), LA-EP2006 was equivalent to reference pegfilgrastim. Secondary efficacy parameters were similar between groups during cycle 1 and across cycles. Safety profiles were also similar between groups. No neutralizing antibodies against pegfilgrastim, filgrastim, or polyethylene glycol were detected. CONCLUSION LA-EP2006 and reference pegfilgrastim were therapeutically equivalent and comparable regarding efficacy and safety in the prevention of neutropenia in patients with early-stage breast cancer receiving TAC. IMPLICATIONS FOR PRACTICE The granulocyte colony-stimulating factor pegfilgrastim is widely used for the prevention of chemotherapy-induced neutropenia. Biosimilars are biologics with similar quality, safety, and efficacy to a reference product that may increase the affordability of treatment compared with their reference compounds. There are currently no approved biosimilars of pegfilgrastim in highly regulated markets. No previous phase III studies have been performed with LA-EP2006. PROTECT-2 was conducted to confirm the similarity of the proposed biosimilar LA-EP2006 to pegfilgrastim. Biosimilar pegfilgrastim (LA-EP2006) may benefit oncology patients by offering increased access to biological treatments that may improve clinical outcomes. This means that patients could potentially be treated prophylactically with biologics rather than only after complications have occurred.

Abstract
PURPOSE Risk of infection increases with severity and duration of chemotherapy-induced neutropenia (CIN). Pegfilgrastim is approved for use on the day after chemotherapy to reduce incidence of infection, as manifested by febrile neutropenia (FN), in patients receiving myelosuppressive chemotherapy. In this study, we compared severity and duration of absolute neutrophil count (ANC) suppression in patients who received pegfilgrastim on the same day as chemotherapy versus the next day. METHODS We combined individual patient data from four Amgen-sponsored clinical trials in which patients with cancer were randomized to receive pegfilgrastim either the same day as chemotherapy or the next day. Severity and duration of ANC suppression were calculated using area over the curve (AOC, the area over the ANC-time response curve and below a given clinical threshold). AOC of ANC and incidences of CIN and FN were compared by day of pegfilgrastim use. RESULTS The analysis included 95 same-day patients and 97 next-day patients. Despite similar ANC at baseline, ANC at nadir was higher among next-day patients than same-day patients. Mean AOC of ANC (cutoff 0.5 × 10(9)/L) among next-day patients was lower by 0.30 (95 % confidence interval: 0.16, 0.43) 10(9)/L × day than same-day patients in cycle 1. Next-day patients had lower incidences of CIN than same-day patients, but there were no significant differences in incidences of FN. CONCLUSIONS Patients who received pegfilgrastim the day after chemotherapy had less severe and shorter suppression of ANC than patients who received pegfilgrastim the same day as chemotherapy.

Abstract
With the approval of pegfilgrastim, the use of dose-dense epirubicin and cyclophosphamide (EC) for breast cancer has become acceptable in Japan. Thus, we aimed to evaluate its safety and tolerability in Japanese patients. Nine breast cancer patients with a high risk of preoperative or postoperative recurrence received EC therapy(epirubicin 90 mg/m(2) and cyclo- phosphamide 600 mg/m(2))for 4 cycles every 2 weeks in combination with a subcutaneous injection of pegfilgrastim (3.6 mg) on day 2 of each cycle. Treatment was discontinued in 1 and extended in 1 of the 9 patients, and the mean relative dose intensity(RDI)was good at 0.93. No serious adverse events were observed, indicating good tolerability. The regimen has potential for use in cases in which the treatment dose needs to be increased. grade 4 neutropenia was observed in all the 9 patients on day 8, with 6 patients developing febrile neutropenia. In Japan, data on changes in neutrophil count associated with pegfilgrastim administration under anthracycline-based chemotherapy are currently insufficient, and further study is required.

Abstract
OBJECTIVE This study aims to compare the cost-effectiveness of various strategies of myeloid growth factor prophylaxis for reducing the risk of febrile neutropenia (FN) in patients with non-Hodgkin lymphoma in Singapore who are undergoing R-CHOP chemotherapy with curative intent. METHODS A Markov model was created to compare seven prophylaxis strategies: 1) primary prophylaxis (PP) with nivestim (biosimilar filgrastim) throughout all cycles of chemotherapy; 2) PP with nivestim during the first two cycles of chemotherapy; 3) secondary prophylaxis (SP) with nivestim; 4) PP with pegfilgrastim throughout all cycles of chemotherapy; 5) PP with pegfilgrastim during the first two cycles of chemotherapy; 6) SP with pegfilgrastim; and 7) no prophylaxis (NP). The perspective of a hospital was taken and cost-effectiveness was expressed as the cost per episode of FN avoided over six cycles of chemotherapy. A probabilistic sensitivity analysis was conducted. RESULTS Strategies 3, 6, and 7 were dominated in the base case analysis by strategy 5. The costs associated with strategies 2, 5, 1, and 4 were US$3,813, US$4,056, US$4,545, and US$5,331, respectively. The incremental cost-effectiveness ratios for strategy 5 vs. strategy 2, strategy 1 vs. strategy 5, and strategy 4 vs. strategy 1 were US$13,532, US$22,565, and US$30,452, respectively, per episode of FN avoided. Strategy 2 has the highest probability to be cost-effective (ranged from 48% to 60%) when the willingness to pay (WTP) threshold is lower than US$10,000 per FN episode prevented. CONCLUSION In Singapore, routine PP with granulocyte colony-stimulating factor (nivestim or pegfilgrastim) is cost-effective for reducing the risk of FN in patients receiving R-CHOP.

Abstract
OBJECTIVES This study aimed to evaluate the efficacy and safety of once-per-cycle balugrastim versus pegfilgrastim for neutrophil support in breast cancer patients receiving myelosuppressive chemotherapy. METHODS Breast cancer patients (n = 256) were randomized to 40 or 50 mg of subcutaneous balugrastim or 6 mg of pegfilgrastim ≈24 hours after chemotherapy (60 mg/m(2) doxorubicin and 75 mg/m(2) docetaxel, every 21 days for up to 4 cycles). The primary efficacy parameter was the duration of severe neutropenia (DSN) in cycle 1. Secondary parameters included DSN (cycles 2-4), absolute neutrophil count (ANC) nadir, febrile neutropenia rates, and time to ANC recovery (cycles 1-4). Safety, pharmacokinetics, and immunogenicity were assessed. RESULTS Mean cycle 1 DSN was 1.0 day with 40 mg of balugrastim, 1.3 with 50 mg of balugrastim, and 1.2 with pegfilgrastim (upper limit of 95% confidence intervals for between-group DSN differences was <1.0 day for both balugrastim doses versus pegfilgrastim). Between-group efficacy parameters were comparable except for time to ANC recovery in cycle 1 (40 mg of balugrastim, 2.0 days; 50 mg of balugrastim, 2.1; pegfilgrastim, 2.6). Median terminal elimination half-life was ≈37 hours for 40 mg of balugrastim, ≈36 for 50 mg of balugrastim, and ≈45 for pegfilgrastim. Antibody response to balugrastim was low and transient, with no neutralizing effect. CONCLUSION Once-per-cycle balugrastim is not inferior to pegfilgrastim in reducing cycle 1 DSN in breast cancer patients receiving chemotherapy; both drugs have comparable safety profiles. IMPLICATIONS FOR PRACTICE This paper provides efficacy and safety data for a new, once-per-cycle granulocyte colony-stimulating factor, balugrastim, for the prevention of chemotherapy-induced neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy. In this phase III trial, balugrastim was shown to be not inferior to pegfilgrastim in the duration of severe neutropenia in cycle 1 of doxorubicin/docetaxel chemotherapy, and the safety profiles of the two agents were similar. Once-per-cycle balugrastim is a safe and effective alternative to pegfilgrastim for hematopoietic support in patients with breast cancer receiving myelosuppressive chemotherapy associated with a greater than 20% risk of developing febrile neutropenia.
