[PMID: 38401695 DOI: 10.1016/j.critrevonc.2024.104306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 02/16/2024] [Accepted: 02/20/2024] [Indexed: 02/26/2024] Open
Abstract
Filgrastim is approved for several indications, including reduction of the incidence and duration of chemotherapy-induced neutropenia and for stem cell mobilization. The filgrastim biosimilar, EP2006, has been available in Europe since 2009, and in the United States since 2015. In this time, preclinical and clinical data used to support the approval of EP2006 have been published. These data established the biosimilarity of EP2006 to reference filgrastim in terms of structure, pharmacokinetics, pharmacodynamics, efficacy, safety, and immunogenicity. Additional real-world evidence studies have also demonstrated equivalent efficacy and safety of EP2006 compared with reference filgrastim, both in the reduction of neutropenia and in stem cell mobilization in clinical practice. This review summarizes these preclinical, clinical, and real-world data, as well as the available cost-effectiveness data, for EP2006 since its approval 15 years ago.

Abstract
Aim: To compare the incidence of febrile neutropenia (FN) after same-day versus next-day pegfilgrastim. Materials & methods: This single-institution, real-world, retrospective electronic health record-based study included patients who received chemotherapy and prophylactic same-day or next-day pegfilgrastim/pegfilgrastim-cbqv. Results: In cycle 1, 117 patients received same-day pegfilgrastim and 180 patients received next-day pegfilgrastim. FN episodes in cycle 1 occurred in 6.0 versus 6.7% of patients with same-day versus next-day pegfilgrastim, respectively (p = 0.814). Across all cycles, 8.5 and 9.4% of patients experienced ≥1 FN episode after same-day versus next-day pegfilgrastim, respectively (p = 0.793). In the breast cancer patient subgroup, FN occurred 3.2% of same-day pegfilgrastim cycles versus 1.8% of next-day pegfilgrastim cycles (p = 0.938). Conclusion: No significant differences were detected between same-day and next-day pegfilgrastim administration.

Abstract
Granulocyte-colony stimulating factor (G-CSF) stimulates bone marrow progenitor cell proliferation and enhances neutrophil production. Exogenous G-CSF administration is indicated for chemotherapy-induced neutropenia management. However, there is a paucity of basic research examining the effects of the concomitant use of G-CSF and chemotherapy on myeloid cells in vivo. Whether concomitant G-CSF and chemotherapy adversely affect myeloid cell proliferation have not been determined. Herein, we examined the effects of the concomitant use of pegfilgrastim and 5-fluorouracil on myeloid cells and peripheral blood cells in mouse models. Balb/c mice were treated intraperitoneally with 5-fluorouracil (20 μg/g b.w.) or a vehicle as a control for 5 days, and pegfilgrastim was administered subcutaneously at 1 μg/g b.w. on day 3. As a result, we demonstrated that the concomitant use of pegfilgrastim suppressed the 5-fluorouracil-induced decrease of granulocytic cells in both bone marrow and peripheral blood in mice. To assess the clinical efficacy of early administration of pegfilgrastim during docetaxel, cisplatin, and 5-fluorouracil therapy in patients with esophageal cancer, we retrospectively identified 42 consecutive patients treated with this regimen. The incidence of both febrile neutropenia and grade 4 neutropenia was significantly lower in patients who received pegfilgrastim than in those who did not receive it (P = 0.002 and P = 0.002, respectively). These results suggest that the concomitant use of pegfilgrastim and chemotherapy, consisting of continuous infusions of 5-fluorouracil, improved chemotherapy-induced neutropenia without detrimental effects on proliferating myeloid granulocytic cells.

Effects of Prophylactic Administration of Granulocyte Colony-Stimulating Factor on Peripheral Leukocyte and Neutrophil Counts Levels After Chemotherapy in Patients With Early-Stage Breast Cancer: A Retrospective Cohort Study. Front Oncol 2022; 12:777602. [PMID: 35547875 PMCID: PMC9084938 DOI: 10.3389/fonc.2022.777602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
Background Both chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN) frequently occur and can lead to dose-limiting toxicity and even fatal chemotherapy side effects. The prophylactic use of recombinant human granulocyte colony-stimulating factor (rhG-CSF), including pegylated rhG-CSF (PEG-rhG-CSF), significantly reduces the risks of CIN and FN during chemotherapy in early-stage breast cancer (ESBC) patients. However, whether the prophylactic use of granulocyte colony-stimulating factor (G-CSF), especially PEG-rhG-CSF, can influence white blood cell (WBC) counts and absolute neutrophil counts (ANCs) after finishing the chemotherapy remains unknown. Therefore, exploring the development and recovery tendency of WBC counts and ANCs during and after chemotherapy is crucial. Objective We aimed to investigate the variation tendency and recovery of WBC counts and ANCs during and after chemotherapy and evaluate the independent factors influencing leukopenia and neutropenia lasting longer after chemotherapy. We also aimed to provide individualized prophylactically leukocyte elevation therapy for breast cancer patients. Methods This single-center retrospective cohort study evaluated 515 ESBC patients who received rhG-CSF or PEG-G-CSF for prophylaxis after adjuvant or neoadjuvant chemotherapy. Blood test reports were analyzed during chemotherapy, and on a 12-month follow-up period after finishing the chemotherapy. The WBC counts and ANCs were measured to assess their variation tendency characteristics and to identify independent factors that influenced the occurrence of leukopenia and neutropenia lasting longer than 12 months after chemotherapy. Results Prophylaxis with rhG-CSF or PEG-rhG-CSF kept the mean values of WBC counts and ANCs within the normal range during chemotherapy, but a significant difference in WBC levels was detected before the end of the last chemotherapy compared to the prechemotherapy period (baseline) (p < 0.001). During the 12-month follow-up after the end of the last chemotherapy, WBC counts and ANCs gradually recovered, but the group that used only PEG-rhG-CSF (long-acting group, p WBC = 0.012) or rhG-CSF (short-acting group, p WBC = 0.0005) had better leukocyte elevation effects than the mixed treatment group (PEG-rhG-CSF mixed rhG-CSF). Besides, the short-acting group had a better neutrophil elevation effect than the longer-acting (p ANC = 0.019) and mixed (p ANC = 0.002) groups. Leukopenia was still present in 92 (17.9%) patients and neutropenia in 63 (12.2%) 12 months after the end of the last chemotherapy. The duration of leukopenia over 12 months was closely associated with the baseline WBC level (p < 0.001), G-CSF types (p = 0.027), and surgical method (p = 0.041). Moreover, the duration of neutropenia over 12 months was closely related to the baseline ANC (p < 0.001), G-CSF types (p = 0.043), and molecular typing (p = 0.025). Conclusion The prophylactic application of G-CSF effectively stabilized the WBC counts and ANCs during chemotherapy in ESBC patients. Nevertheless, the recovery of WBC counts and ANCs after chemotherapy varied between different G-CSF treatment groups. The risk of leukopenia and neutropenia persisting for more than 12 months after chemotherapy was associated with G-CSF types, the baseline level of WBC count/ANCs, surgical method, and molecular typing.

Abstract
Aim: To determine the incidence of chemotherapy-induced febrile neutropenia (FN) and related outcomes after same-day pegfilgrastim in lung cancer. Materials & methods: This single-center, retrospective study evaluated electronic health records of patients with lung cancer treated between 2013-2018. The main end points were incidence of FN and grade 3/4 neutropenia after the first and across all chemotherapy cycles. Results: A total of 114 patients received same-day pegfilgrastim in 384 cycles. The incidence of FN and grade 3/4 neutropenia was 2.3 and 25% after the first chemotherapy cycle and 1.6 and 10.4% across all cycles, respectively. Conclusion: Same-day prophylactic pegfilgrastim in patients with lung cancer may be a suitable option, owing to its low incidence of FN and related outcomes.

Abstract
Background: Real-world data suggests superiority of pegfilgrastim (PEG) over filgrastim (FIL) in reducing the incidence of chemotherapy-induced febrile neutropenia (FN), probably attributable to underdosed FIL in practice. We used real-world data to assess the cost-effectiveness of primary prophylaxis with PEG versus FIL in cancer patients at intermediate-to-high risk of FN from a US payer perspective. Methods: A Markov model with lifetime horizon. Results: For the high-risk group, PEG (vs FIL) biosimilars resulted in 0.43 FN events prevented (FNp), 0.27 quality-adjusted life-years gained (QALYg) and a cost saving of USD$5703. For the intermediate-risk group, PEG biosimilar led to 0.18 FNp and 0.12 QALYg, at USD$9674/FNp and USD$14,502/QALYg. Conclusion: PEG biosimilars may provide opportunities to optimize FN management in patients with intermediate-to-high FN risk.

Supportive therapies in the prevention of chemotherapy-induced febrile neutropenia and appropriate use of granulocyte colony-stimulating factors: a Delphi consensus statement. Support Care Cancer 2022; 30:9877-9888.

Abstract
PURPOSE Data indicate that the use of prophylactic granulocyte colony-stimulating factors (G-CSFs) for chemotherapy-induced febrile neutropenia (FN) in routine practice is not consistent with guideline recommendations. The initiative "supportive care for febrile neutropenia prevention and appropriateness of G-CFS use" was undertaken to address the issue of inappropriate prescription of G-CSFs and to improve guideline adherence in the treatment of FN. METHODS In a two-round Delphi procedure, 36 medical oncologists reviewed clinically relevant recommendations on risk assessment, the appropriate use of G-CSFs, and the prevention of FN based on available literature and individual clinical expertise. RESULTS The consensus was reached on 16 out of 38 recommendations, which are backed by evidence from randomised clinical trials and routine clinical practice. The medical oncologists agreed that the severity of neutropenia depends on patients' characteristics and chemotherapy intensity, and therefore, the risk of severe neutropenia or FN should be assessed at each chemotherapy cycle so as to initiate prophylaxis with G-CSFs if required. The use of biosimilar G-CSFs, with similar efficacy and safety profiles to the originator biologic, has improved the availability and sustainability of cancer care. The timing of supportive therapy is crucial; for example, long-acting G-CSF should be administered 24-72 h after chemotherapy administration. Each biological agent has a recommended administration dose and duration, and it is important to follow these recommendations to avoid complications associated with under-prophylaxis. CONCLUSION It is hoped that these statements will help to increase adherence to guideline recommendations for appropriate G-CSF use and improve patient care.

Abstract
BACKGROUND Chemotherapy-induced febrile neutropenia (FN) is prevented or minimized with granulocyte colony-stimulating factors (G-CSFs). Several G-CSF biosimilars are approved in the United States. The Biologics and Biosimilars Collective Intelligence Consortium (BBCIC) is a nonprofit initiative whose objective is to provide scientific evidence on real-world use and comparative safety and effectiveness of biologics and biosimilars using the BBCIC distributed research network (DRN). PATIENTS AND METHODS We describe real-world G-CSF use in patients with breast or lung cancer receiving first-cycle chemotherapy associated with high FN risk. We assessed hospitalizations for FN, availability of absolute neutrophil counts, and G-CSF-induced adverse events to inform future observational comparative effectiveness studies of G-CSF reference products and their biosimilars. A descriptive analysis of 5 participating national health insurance plans was conducted within the BBCIC DRN. RESULTS A total of 57,725 patients who received at least one G-CSF dose were included. Most (92.5%) patients received pegfilgrastim. FN hospitalization rates were evaluated by narrow (<0.5%), intermediate (1.91%), and broad (2.99%) definitions. Anaphylaxis and hyperleukocytosis were identified in 1.15% and 2.28% of patients, respectively. This analysis provides real-world evidence extracted from a large, readily available database of diverse patients, characterizing G-CSF reference product use to inform the feasibility of future observational comparative safety and effectiveness analyses of G-CSF biosimilars. We showed that the rates of FN and adverse events in our research network are consistent with those reported by previous small studies. CONCLUSIONS Readily available BBCIC DRN data can be used to assess G-CSF use with the incidence of FN hospitalizations. Insufficient laboratory result data were available to report absolute neutrophil counts; however, other safety data are available for assessment that provide valuable baseline data regarding the effectiveness and safety of G-CSFs in preparation for comparative effectiveness studies of reference G-CSFs and their biosimilars.

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
PURPOSE OF REVIEW This review presents the analysis of recently published studies about the benefit from granulocyte-colony stimulating factors (G-CSF) in older cancer patients receiving chemotherapy. RECENT FINDINGS During the last years, no major study aiming to confirm the clinical benefit of G-CSF prophylaxis in older patients treated with chemotherapy has been published. Nonetheless, all the data made recently available confirm that age, especially if other comorbid conditions are present as well, is a major risk factor for febrile neutropenia occurrence and that G-CSF prophylaxis can reduce significantly that risk. SUMMARY New modalities of administering G-CSF prophylaxis might be considered in older people in the future. Among these approaches, the 'same day' administration of prophylaxis and chemotherapy and the development of less-expensive approaches for G-CSF prophylaxis, such as the use of biosimilars are studied.

Abstract
BACKGROUND Chemotherapy-related side effects and their management in patients with Non-Hodgkin's Lymphoma (NHL) are not well defined in developing countries, including Kenya. This needs addressing considering the high number of patients with cancer in these countries. Consequently, we sought to determine the common side effects of chemotherapy used to treat NHL in pediatric patients and its implications. METHODS Observational study conducted at the Kenyatta National Hospital in patients aged ≤15 years. Some data was collected by reviewing patients' records admitted to the pediatric oncology ward, December 2016 to May 2017; and additional data was collected retrospectively (review of patients' records with NHL, January-2014 to May-2017). Data were analyzed descriptively. RESULTS Overall, out of the identified NHL patients (n = 85), 93% (n = 79) had chemotherapy-related side effects. The majority of patients suffered from side effects were managed; apart from 23% to 24% of the documented anemia and hypersensitivity, respectively. CONCLUSIONS Whilst the majority of the reported side-effects were being managed, the lack of management of some side effects raises real concerns since this indicates either failure to manage or failure to document their management in patients' records, both of which should be addressed appropriately to improve future care.
