Abstract
Although granulocyte colony-stimulating factor (G-CSF) reduces the incidence, duration, and severity of neutropenia, its prophylactic use for acute myeloid leukemia (AML) remains controversial due to a theoretically increased risk of relapse. The present study investigated the effects of G-CSF as primary prophylaxis for AML with remission induction therapy. A detailed literature search for related studies was performed using PubMed, Ichushi-Web, and the Cochrane Library. Data were independently extracted and assessed by two reviewers. A qualitative analysis of pooled data was conducted, and the risk ratio with corresponding confidence intervals was calculated in the meta-analysis and summarized. Sixteen studies were included in the qualitative analysis, nine of which were examined in the meta-analysis. Although G-CSF significantly shortened the duration of neutropenia, primary prophylaxis with G-CSF did not correlate with infection-related mortality. Moreover, primary prophylaxis with G-CSF did not affect disease progression/recurrence, overall survival, or adverse events, such as musculoskeletal pain. However, evidence to support or discourage the use of G-CSF as primary prophylaxis for adult AML patients with induction therapy remains limited. Therefore, the use of G-CSF as primary prophylaxis can be considered for adult AML patients with remission induction therapy who are at a high risk of infectious complications.

Abstract
CONTEXT The need for patient navigator is growing, and there is a lack of cost evaluation, especially during survivorship. OBJECTIVE The objective of this study is to evaluate the cost-effectiveness of an Ambulatory Medical Assistance (AMA) programme in patients with haematological malignancies (HM). DESIGN A cost-effectiveness analysis of the AMA programme was performed compared to a simulated control arm. SETTING An interventional, single-arm and prospective study was conducted in a French reference haematology-oncology centre between 2016 and 2020. PARTICIPANTS Adult patients were enrolled with histologically documented malignant haematology, during their active therapy phase, and treated either by intravenous chemotherapy or oral therapy. METHODS An extrapolation of the effectiveness was derived from a similar nurse monitoring programme (CAPRI study). Cost effectiveness of the programme was evaluated through adverse events of Grade 3 or 4 avoided in different populations. RESULTS Included patient (n = 797) from the AMA programme were followed during 125 days (IQR: 0-181), and adverse events (Grade 3/4) were observed in 10.1% of patients versus 13.4% in the simulated control arm. The overall cost of AE avoided was estimated to €81,113, leading to an ICER of €864. CONCLUSION The AMA programme was shown to be cost-effective compared to a simulated control arm with no intervention.

Abstract
High-dose chemotherapy (HD-Cx) in refractory germ cell cancer (GCC) is effective but limited data are available concerning the optimal approach for stem cell mobilization (SCM) in these patients. In this analysis 102 patients undergoing SCM during first (n = 25) or subsequent treatment lines (n = 77) were analyzed. Subcutaneous injections of granulocyte colony-stimulating factor (G-CSF) were given once daily (group 1) in 52 patients (51%), twice daily (group 2) in 39 patients (38%) or one injection Pegylated-G-CSF (PegG-CSF) (group 3) in eleven patients (11%) after one cycle of mobilization chemotherapy. Plerixafor was administered 13 times in group 1, seven times in group 2 and once in group 3. Overall, 77 (75%) patients achieved successful SCM defined as ≥8*106 CD34+ cells/kg body weight for three consecutive HD-Cx plus one backup dose. In group 1, 40 of 52 patients (77%) achieved successful SCM with a median of 11 G-CSF injections, in group 2, 27 of 39 patients (69%) with a median of 14 G-CSF injections and in group 3, 10 of 11 patients (91%) with one injection of PegG-CSF. SCM was more successful if conducted during first-line chemotherapy (p = 0.016) and associated with a beneficial outcome concerning overall survival (p = 0.02) if performed satisfactorily.

Abstract
AIMS Proliferating hematopoietic stem and progenitor cells (HSPCs) are susceptible to chemotherapy-induced damage, resulting in myelosuppressive adverse events (AEs) such as neutropenia, anemia, and thrombocytopenia that are associated with high health care costs and decreased quality of life (QoL). In this study, a trial-based cost-effectiveness analysis was performed to help assess the economic impact of administering trilaciclib, a myeloprotective therapy that protects multilineage HSPCs from chemotherapy-induced damage, prior to standard first-line chemotherapy, using data from a pivotal Phase II study of trilaciclib in the setting of extensive-stage small cell lung cancer (ES-SCLC, NCT03041311). METHOD The aim of this study was to assess the cost-effectiveness of administering trilaciclib prior to chemotherapy versus chemotherapy alone among patients with ES-SCLC from a United States payer perspective. Data on the rate and frequency of myelosuppressive AEs and health utility were derived from the pivotal study of trilaciclib. Costs of managing myelosuppressive AEs and costs of chemotherapy treatment were sourced from published literature. Outcomes included the number of myelosuppressive AEs, costs (in 2021 US dollars), quality-adjusted life-years (QALYs), incremental cost, incremental QALY, and an incremental cost-effectiveness ratio. RESULTS Administering trilaciclib prior to chemotherapy was associated with a reduction in neutropenia (82%), febrile neutropenia (75%), anemia (43%), and thrombocytopenia (96%) compared with chemotherapy alone. Additionally, trilaciclib prior to chemotherapy was cost-saving compared with chemotherapy alone ($99,919 vs $118,759, respectively) and associated with QALY improvement (0.150 vs 0.145, respectively). Probabilistic sensitivity analyses showed 58% of iterations projecting cost savings and QALY improvement with trilaciclib. CONCLUSIONS The findings suggest that the use of trilaciclib prior to first-line chemotherapy in patients with ES-SCLC can be cost-beneficial owing to fewer myelosuppressive AEs and lower costs, together with a favorable QoL profile.

Abstract
Purpose: The aim of the study was to evaluate the cost-effectiveness of PEGylated recombinant human granulocyte-stimulating factor (PEG-rhG-CSF) as a means of achieving primary and secondary prophylaxis against chemotherapy-induced neutropenia cancer cases. Methods: Individuals who underwent PEG-rhG-CSF therapeutics were monitored for 12 months, together with thorough examination of individual medical records for extracting medical care costs. Both prophylaxis-based therapeutic options (primary/secondary) were scrutinized for cost-effectiveness, using a decision-making analysis model which derived the perspective of Chinese payers. One-way and probabilistic sensitivity analyses were used to assess the robustness of the model. Results: In summary, 130 clinical cases treated using PEG-rhG-CSF prophylaxis were included in this study: 51 within the primary prophylaxis (PP) group and 79 within the secondary prophylaxis (SP) group. Compared with SP, PP-based PEG-rhG-CSF successfully contributed to a 14.3% reduction in febrile neutropenia. In general, PP was estimated to reduce costs by $4,701.81 in comparison to SP, with a gain of 0.02 quality-adjusted life years (QALYs). Equivalent results were found in differing febrile neutropenia (FN) risk subgroups. Sensitivity analyses found the model outputs to be most affected for the average time of hospitalization and for the cost of FN. Conclusion: From the perspective of Chinese payers, PP with PEG-rhG-CSF should be considered cost-effective compared to SP strategies in patients who received chemotherapy regimens with a middle- to high-risk of FN.

Abstract
Filgrastim prophylaxis, both primary and secondary, was rapidly incorporated into clinical practice in the 1990s. When pegfilgrastim became available in 2002, it quickly replaced filgrastim as the colony-stimulating factor (CSF) of choice for prophylaxis. Use of prophylaxis increased markedly in the first decade of this century and has stabilized during the present decade. Data concerning real-world CSF prophylactic practice patterns are limited but suggest that both primary and secondary prophylaxis are common, and that use is frequently inappropriate according to guidelines. The extent of inappropriate use is controversial, as are issues concerning the cost-effectiveness of prophylaxis versus no prophylaxis and the cost-effectiveness of primary prophylaxis versus secondary prophylaxis. Nevertheless, CSF prophylaxis is firmly established as a valuable adjunct to chemotherapy and will almost certainly continue to be widely used for the foreseeable future. In this article, we chronicle the use and impact of CSF prophylaxis in US patients receiving myelosuppressive chemotherapy for non-myeloid malignancies. We emphasize the interplay of expert opinion, clinical evidence, and economic factors in shaping the use of CSFs in clinical practice over time, and, with the recent introduction of new CSF agents and options, we aim to provide useful clinical and economic information for healthcare decision makers.

Abstract
OBJECTIVES To examine the cost-effectiveness of lipegfilgrastim versus pegfilgrastim as primary prophylaxis in women with early stage breast cancer. METHODS Two Markov models including a chemotherapy and a post-chemotherapy models were constructed with a time horizon of 12 weeks and 30 years, respectively. All the transition probabilities and utility weights were derived from clinical trials and/or published literatures. The costs populated in the chemotherapy model were extracted from Medicare, Pharmaceutical Benefit Scheme and the Independent Hospital Pricing Authority. No cost was considered in the post-chemotherapy model. Sensitivity analyses were performed to test the robustness of the results. RESULTS From the first chemotherapy model, lipegfilgrastim was associated with fewer episodes of severe neutropenia (SN) (N = 142 per 1000 patients treated), febrile neutropenia (FN) (N = 29 per 1000 patients treated), infection (N = 17 per 1000 patients treated) and chemotherapy delayed (N = 170 per 1000 patients treated) and lower cost ($116.88 less per patient treated). The post-chemotherapy model indicated lipegfilgrastim led to higher gains in both life years (18.72 versus 18.61) and quality-adjusted life years (17.28 versus 17.18) in comparison to pegfilgrastim. Sensitivity analysis showed that the results from the chemotherapy model is very sensitive to the baseline risk of SN; while from the probabilistic sensitivity analysis, lipegfilgrastim was likely to be more cost-effective than pegfilgrastim based on two models. CONCLUSIONS Lipegfilgrastim was likely to be a cost-effective alternative to pegfilgrastim as primary prophylaxis. The sensitivity analysis showed the confidence interval for the cost and benefit outcomes overlapped to a great extent, suggesting an insignificant difference.

Cost-Utility Analysis of Lipegfilgrastim Compared to Pegfilgrastim for the Prophylaxis of Chemotherapy-Induced Neutropenia in Patients with Stage II-IV Breast Cancer. Front Pharmacol 2017; 8:614. [PMID: 28955224 PMCID: PMC5601405 DOI: 10.3389/fphar.2017.00614] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Accepted: 08/23/2017] [Indexed: 11/13/2022] Open
Abstract
Background: Lipegfilgrastim (Lonquex®) has demonstrated to be non-inferior to pegfilgrastim (Neulasta®) in reducing the duration of severe neutropenia (SN) in patients with stage II-IV breast cancer. Compared to pegfilgrastim, lipegfilgrastim also demonstrated statistically significant lower time to ANC recovery in cycles 1-3, lower incidence of SN in cycle 2 and lower depth of absolute neutrophil count (ANC) nadir in cycles 2 and 3. The aim of this study was to quantify the cost utility of lipegfilgrastim compared to pegfilgrastim in stage II-IV breast cancer patients, taking the perspective of the Belgian payer over a lifetime horizon. Methods: Two Markov models were developed to track on- and post-chemotherapy related complications, including SN, febrile neutropenia (FN), chemotherapy dose delay, chemotherapy relative dose intensity of less than 85%, infection, death rates, and quality-adjusted life years (QALYs). Data on costs (2015 value) and effects were obtained from literature, national references, and complemented by a survey of clinical experts using a modified Delphi method. Both deterministic and probabilistic sensitivity analyses were carried out. Outcomes measures included costs, QALYs and life-years (LY). Results: At current equivalent price of €1,169, treatment with lipegfilgrastim was associated with overall costs of €9,845 vs. €10,208 for pegfilgrastim and overall QALYs of 13.977 vs. 13.925 for pegfilgrastim. Life expectancy was increased by 21 days (or 0.058 LY gained). The difference in costs stem from avoided infection, SN and FN cases in the lipegfilgrastim compared to the pegfilgrastim group. Similarly, the difference in QALYs was explained by the difference in the number of patients in the chemotherapy/G-CSF Markov state followed by infection and FN between lipegfilgrastim and pegfilgrastim. The probability of lipegfilgrastim to be cost-effective compared to pegfilgrastim was 68, 79, and 83% at the willingness-to-pay thresholds (WTP) of €10,000, €30,000 and €50,000 per QALY gained, respectively. At a WTP threshold of €30,000 per QALY gained, lipegfilgrastim was cost-effective up to €1,500 across all age bands and cancer stages, compared to the current price. Conclusions: Lipegfilgrastim is a cost-effective use of health care resources in patients with stage II-IV breast cancer.

Abstract
The adoption of primary (PP) versus secondary prophylaxis (SP) of febrile neutropenia (FN), with granulocyte colony-stimulating factors (G-CSF), for adjuvant chemotherapy (AC) regimens in breast cancer (BC) could be affected by its "value for money". This systematic review examined (i) cost-effectiveness of PP versus SP, (ii) FN threshold at which PP is cost-effective including the guidelines 20 % threshold and (iii) potential impact of G-CSF efficacy assumptions on outcomes. The systematic review identified all cost-effectiveness/cost-utility analyses (CEA/CUA) involving PP versus SP G-CSF for AC in BC that met predefined inclusion/exclusion criteria. Five relevant CEA/CUA were identified. These CEA/CUA examined different AC regimens (TAC = 2; FEC-D = 1; TC = 2) and G-CSF formulations (filgrastim "F" = 4; pegfilgrastim "P" = 4) with varying baseline FN-risk (range 22-32 %), mortality (range 1.4-6.0 %) and utility (range 0.33-0.47). The potential G-CSF benefit, including FN risk reduction with P versus F, varied among models. Overall, relative to SP, PP was not associated with good value for money, as per commonly utilized CE thresholds, at the baseline FN rates examined, including the consensus 20 % FN threshold, in most of these studies. The value for money associated with PP versus SP was primarily dependent on G-CSF benefit assumptions including reduced FN mortality and improved BC survival. PP G-CSF for FN prevention in BC patients undergoing AC may not be a cost-effective strategy at the guidelines 20 % FN threshold.

Cost-utility analyses of drug therapies in breast cancer: a systematic review. Breast Cancer Res Treat 2016; 159:407-24.

Abstract
The economic evaluation (EE) of health care products has become a necessity. Their quality must be high in order to trust the results and make informed decisions. While cost-utility analyses (CUAs) should be preferred to cost-effectiveness analyses in the oncology area, the quality of breast cancer (BC)-related CUA has been given little attention so far. Thus, firstly, a systematic review of published CUA related to drug therapies for BC, gene expression profiling, and HER2 status testing was performed. Secondly, the quality of selected CUA was assessed and the factors associated with a high-quality CUA identified. The systematic literature search was conducted in PubMed, MEDLINE/EMBASE, and Cochrane to identify published CUA between 2000 and 2014. After screening and data extraction, the quality of each selected CUA was assessed by two independent reviewers, using the checklist proposed by Drummond et al. The analysis of factors associated with a high-quality CUA (defined as a Drummond score ≥7) was performed using a two-step approach. Our systematic review was based on 140 CUAs and showed a wide variety of methodological approaches, including differences in the perspective adopted, the time horizon, measurement of cost and effectiveness, and more specially health-state utility values (HSUVs). The median Drummond score was 7 [range 3-10]. Only one in two of the CUA (n = 74) had a Drummond score ≥7, synonymous of "high quality." The statistically significant predictors of a high-quality CUA were article with "gene expression profiling" topic (p = 0.001), consulting or pharmaceutical company as main location of first author (p = 0.004), and articles with both incremental cost-utility ratio and incremental cost-effectiveness ratio as outcomes of EE (p = 0.02). Our systematic review identified only 140 CUAs published over the past 15 years with one in two of high quality. It showed a wide variety of methodological approaches, especially focused on HSUVs. A critical appraisal of utility values is necessary to better understand one of the main difficulties encountered by authors and propose areas for improvement to increase the quality of CUA. Since the last 5 years, there is a tendency toward an improvement in the quality of these studies, probably coupled with economic context, a better and widely spreading of recommendations and thus appropriation by medical practitioners. That being said, there is an urgent need for mandatory use of European and international recommendations to ensure quality of such approaches and to allow easy comparison.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is commonly administered to patients with Hodgkin lymphoma (HL) with neutropenia. We constructed a decision-analytic model to compare the cost-effectiveness of secondary prophylaxis with G-CSF to a strategy of 'no G-CSF' in response to severe neutropenia for adults with advanced-stage HL treated with ABVD. A Canadian public health payer's perspective was considered and costs were presented in 2013 Canadian dollars. The quality-adjusted life years (QALYs) attained with the G-CSF and 'no G-CSF' strategies were 1.403 and 1.416, respectively. Costs for the strategies with and without G-CSF were $38,971 and $33,982, respectively. In the base case analysis, the 'no G-CSF' strategy was associated with cost savings and improved QALYs; therefore, 'no G-CSF' was the dominant approach. For patients with severe neutropenia during ABVD chemotherapy for advanced-stage HL, a strategy without G-CSF support is associated with improved quality-adjusted outcomes, cost savings, and is the preferred approach.

Abstract
PURPOSE OF REVIEW Clinical practice guidelines for the prevention of febrile neutropenia in patients receiving cancer chemotherapy utilizing the myeloid growth factors have been developed by several major international professional organizations. This review provides updates on the current status of these guidelines and summarizes recent reported studies currently under review by guideline panels which may alter guideline recommendations. RECENT FINDINGS Whereas the consensus guidelines from the National Comprehensive Cancer Network (NCCN) are updated annually, previous evidence-based recommendations from the American Society of Clinical Oncology (ASCO) and the European Organisation for Research and Treatment of Cancer (EORTC) are currently undergoing an update in their evidence base and recommendations. These updates will consider and base new recommendations on recent important studies related to the efficacy, safety, and cost of these agents in the prevention of neutropenic complications including febrile neutropenia. New information relating to the risk of second malignancies and the ability of the myeloid growth factors to sustain or increase chemotherapy dose intensity and improve overall survival is reviewed. SUMMARY Current guideline recommendations for the prevention of febrile neutropenia are reviewed along with recent published results likely to alter future guideline recommendations on the use of these agents.

Abstract
SUMMARY Aim: To determine the incidence of febrile neutropenia (FN) following adjuvant chemotherapy with docetaxel, carboplatin and trastuzumab (TCH) for early-stage breast cancer and the grade of neutropenia after cycle one. Methods: A retrospective multicenter audit of patients with early-stage breast cancer treated with TCH, was conducted at four Australian hospitals between October 2009 and September 2013. Results: Of 79 patients analyzed, data from 78 women were evaluated for FN incidence and data from 64 women were evaluated for grade of neutropenia. After cycle one of TCH, 26 patients developed FN (33.3%). Following all cycles, 32 patients developed FN (41.0%). There was no statistical difference in the incidence of FN between hospitals or between age groups (above or below 65 years). After cycle one, ten patients developed grade 3 neutropenia (15.6%) and 37 patients developed grade 4 neutropenia (57.8%). Conclusion: This study demonstrates a high incidence of FN post-TCH chemotherapy thus supporting the use of granulocyte colony-stimulating factor as primary prophylaxis.

Abstract
INTRODUCTION In the USA, neutropenia-related hospitalization is estimated to occur in 34.2 cases per 1,000 chemotherapy-treated patients. The cost of hospitalization is significant with estimates ranging, on average, from $10,000 to $30,000 per neutropenia-related hospitalization. Prophylactic use of granulocyte colony-stimulating factor (G-CSF) significantly reduces the risk and duration of neutropenia-related negative events. However, the exact economic benefits of using G-CSF prophylactically are not completely known. The objective of this review is to examine the cost of G-CSF as primary prophylaxis (PP) as well as when used reactively to treat severe neutropenia (SN) or febrile neutropenia (FN). METHODS Electronic databases were searched for studies published up to January 2014. RESULTS The evidence supporting the cost-effectiveness of PP use of G-CSF is inconsistent. The cost savings of PP use of G-CSF associated with the reduction of neutropenia-related events are offset by the increased costs associated with improved chemotherapy administration. Cost savings due to the reduction in mortality and disease/symptoms and use of dose-dense regimens have not been adequately incorporated into previous cost-effectiveness studies. Available data suggest that using G-CSF in conjunction with antibiotics is more cost-effective than antibiotics alone when treating patients with SN/FN. Recent studies of biosimilars suggest that they are as effective as originator G-CSFs and, given their lower cost, could represent a cost-effective alternative. Finally, studies have not taken into consideration the indirect patient costs of experiencing a neutropenia-related event. CONCLUSION G-CSF use is effective in preventing SN/FN. Costs due to hospitalization and other neutropenia-related events are lower in patients treated with G-CSF as PP versus untreated patients. Despite this, many studies have not found solid evidence for the overall cost-effectiveness of PP use of G-CSF. One possibility for this is that patients receiving G-CSF prophylactically often receive more intense chemotherapy regimens, have better relative dose intensity, and fewer dose delays, and thereby have greater costs associated with chemotherapy administration than patients who do not receive G-CSF.

Abstract
BACKGROUND Tamoxifen therapy reduces the risk of breast cancer but increases the risk of serious adverse events including endometrial cancer and thromboembolic events. OBJECTIVES The cost effectiveness of using a commercially available breast cancer risk assessment test (BREVAGen™) to inform the decision of which women should undergo chemoprevention by tamoxifen was modeled in a simulated population of women who had undergone biopsies but had no diagnosis of cancer. METHODS A continuous time, discrete event, mathematical model was used to simulate a population of white women aged 40-69 years, who were at elevated risk for breast cancer because of a history of benign breast biopsy. Women were assessed for clinical risk of breast cancer using the Gail model and for genetic risk using a panel of seven common single nucleotide polymorphisms. We evaluated the cost effectiveness of using genetic risk together with clinical risk, instead of clinical risk alone, to determine eligibility for 5 years of tamoxifen therapy. In addition to breast cancer, the simulation included health states of endometrial cancer, pulmonary embolism, deep-vein thrombosis, stroke, and cataract. Estimates of costs in 2012 US dollars were based on Medicare reimbursement rates reported in the literature and utilities for modeled health states were calculated as an average of utilities reported in the literature. A 50-year time horizon was used to observe lifetime effects including survival benefits. RESULTS For those women at intermediate risk of developing breast cancer (1.2-1.66 % 5-year risk), the incremental cost-effectiveness ratio for the combined genetic and clinical risk assessment strategy over the clinical risk assessment-only strategy was US$47,000, US$44,000, and US$65,000 per quality-adjusted life-year gained, for women aged 40-49, 50-59, and 60-69 years, respectively (assuming a price of US$945 for genetic testing). Results were sensitive to assumptions about patient adherence, utility of life while taking tamoxifen, and cost of genetic testing. CONCLUSIONS From the US payer's perspective, the combined genetic and clinical risk assessment strategy may be a moderately cost-effective alternative to using clinical risk alone to guide chemoprevention recommendations for women at intermediate risk of developing breast cancer.

Abstract
OBJECTIVE Evaluate the cost-effectiveness of primary prophylaxis (PP) or secondary prophylaxis (SP) with pegfilgrastim, filgrastim (6-day and 11-day), or no prophylaxis to reduce the risk of febrile neutropenia (FN) in patients with recurrent ovarian cancer receiving docetaxel or topotecan. METHODS A Markov model was used to evaluate the cost-effectiveness of PP vs SP from a US payer perspective. Model inputs, including the efficacy of each strategy (relative risk of FN with prophylaxis compared to no prophylaxis) and mortality, costs, and utility values were estimated from public sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per FN event avoided, incremental cost per life-year saved (LYS), and incremental cost per quality-adjusted life-year (QALY) gained over a lifetime horizon. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted. RESULTS For patients receiving docetaxel, the incremental cost-effectiveness ratio (ICER) for PP vs SP with pegfilgrastim was $7900 per QALY gained, and PP with pegfilgrastim dominated all other comparators. For patients receiving topotecan, PP with pegfilgrastim dominated all comparators. Model results were most sensitive to baseline FN risk. PP vs SP with pegfilgrastim was cost effective in 68% and 83% of simulations for docetaxel and in >99% of simulations for topotecan at willingness-to-pay thresholds of $50,000 and $100,000 per QALY. CONCLUSIONS PP with pegfilgrastim should be considered cost effective compared to other prophylaxis strategies in patients with recurrent ovarian cancer receiving docetaxel or topotecan with a high risk of FN.

Abstract
INTRODUCTION Granulocyte colony-stimulating factor (G-CSF; filgrastim) and its pegylated form (pegfilgrastim) are widely used to treat neutropenia associated with myelosuppressive chemotherapy and bone marrow transplantation, AIDS-associated or drug-induced neutropenia, and neutropenic diseases. G-CSF facilitates restoration of neutrophil counts, decreases incidence of infection/febrile neutropenia and reduces resource utilization. G-CSF is also widely used to mobilize peripheral blood stem cells for hematopoietic transplant. AREAS COVERED We review the therapeutic use, cost effectiveness and disease impact of G-CSF for neutropenia, development of G-CSF biosimilars and current next-generation discovery efforts. EXPERT OPINION G-CSF has impacted the treatment and survival of patients with congenital neutropenias. For chemotherapy-associated neutropenia, cost effectiveness and impact on survival are still unclear. G-CSFs are expensive and require systemic administration. Market entry of new biosimilars, some with enhanced half-life profiles, will probably reduce cost and increase cost effectiveness. There is no evidence that marketed or late development biosimilars display effectiveness superior to current G-CSFs. Second-generation compounds that mimic the activity of G-CSF at its receptor, induce endogenous ligand(s) or offer adjunct activity have been reported and represent attractive G-CSF alternatives, but are in preclinical stages. A significant therapeutic advance will require reduced depth and duration of neutropenia compared to current G-CSFs.

Abstract
Objective To examine the incidence, treatment, and consequences of febrile neutropenia across inpatient and outpatient care settings. Methods Data were obtained from Humedica's National Electronic Health Record-Derived Longitudinal Patient-Level Database (2007–2010). The study population included adult patients who received myelosuppressive chemotherapy for a solid tumor or non-Hodgkin’s lymphoma. For each patient, each chemotherapy regimen course and each cycle within each regimen course was characterized. Febrile neutropenia episodes were identified on a cycle-specific basis based on any of the following: (1) absolute neutrophil count <1.0 × 109/L and evidence of infection or fever; (2) inpatient diagnosis of neutropenia, fever, or infection; (3) outpatient diagnosis of neutropenia and non-prophylactic antimicrobial use; or (4) mention of febrile neutropenia in physician notes. Febrile neutropenia episodes were categorized as inpatient or outpatient based on the initial setting of care (i.e. acute-care inpatient facility vs. ambulatory care facility). Febrile neutropenia consequences included hospital length of stay and mortality (inpatient cases only), as well as number of febrile neutropenia-related outpatient encounters. Results Among the 2131 patients in this study, 401 experienced a total of 458 febrile neutropenia episodes. Risk of febrile neutropenia during the chemotherapy regimen course was 16.8% (95% CI: 15.3, 18.4). In cycle 1 alone, risk of febrile neutropenia was 8.1% (7.1, 9.3). Most febrile neutropenia episodes (83.2%) were initially treated in the inpatient setting; the hospital mortality rate was 8.1% (5.8, 11.1), and mean hospital length of stay was 8.4 days (7.7, 9.1). Among febrile neutropenia episodes initially treated in the outpatient setting (16.8%), the mean number of outpatient management encounters was 2.6 (2.1, 3.1), most of which were in the physician’s office (69.2%) or emergency department (26.9%). Conclusions Febrile neutropenia remains a common occurrence among patients receiving myelosuppressive chemotherapy and typically results in extended hospitalization and, for many patients, death. A minority of patients are, however, treated exclusively on an outpatient basis.

Abstract
OBJECTIVE The objective of this study was to assess the value of research of the RxPONDER study, an ongoing comparative effectiveness RCT designed to evaluate a 21-gene profile in early stage, node-positive breast cancer. METHODS We developed a disease-based decision-analytic model to compare use of the 21-gene profile versus standard care. Key clinical data were derived from SWOG-8814, an RCT of chemotherapy in lymph node-positive breast cancer. Other model parameters were obtained from published sources. Probabilistic simulations and value of information calculations were used to assess the expected value of sample information (EVSI) and the expected value of sample parameter information (EVSPI). RESULTS The cost of the RxPONDER trial is expected to be at least $27 million. The expected value of research of the RxPONDER trial ranged from $450 million to $1 billion, representing a return of 17 to 39 times the projected cost of the trial. The primary objective of RxPONDER, to assess survival, had the largest estimated value relative to other model inputs. The value of RxPONDER increased by $50 million to $100 million after stakeholder input on additional data collection. CONCLUSION The RxPONDER study appears to represent a good investment of public research funds. Stakeholder engagement and assessment of the return on investment should be considered to optimize and quantify the value of comparative effectiveness studies.

Abstract
BACKGROUND Use of granulocyte colony-stimulating factor (g-csf) as primary prophylaxis against chemotherapy-induced neutropenia has significant cost implications. We examined use of g-csf for early-stage breast cancer patients at our centre. The study also examined the pattern of nurse-led patient teaching with respect to drug self-administration. METHODS Patients who received g-csf between November 2009 and October 2010 were identified from pharmacy records. After consent had been obtained, electronic charts were examined to extract data on chemotherapy and use of g-csf. Patients were contacted by telephone to obtain information on the utilization of home-care nursing visits for g-csf administration. RESULTS The study analyzed 36 patients. Median age was 58 years (range: 31-78 years). Of the 36 patients, 30 (83%) had received adjuvant treatment, and 6 (17%), neoadjuvant treatment. Most patients (71%) received 10 days (range: 7-10 days) of filgrastim. Of the 36 patients, 29 (81%) received g-csf as primary prophylaxis. In 90% of those patients, primary prophylaxis commenced with the taxane component of treatment. Of the 36 patients, 7 (19%) received g-csf after neutropenia, including 2 who had febrile neutropenia. In 96% of the patients, injections were received at home with the help of a nurse; those patients were subsequently taught self-injection techniques. The median number of nursing visits was 2 (range: 1-3 visits). Most patients were satisfied with the home care and g-csf teaching they received. CONCLUSIONS Most of the g-csf used in breast cancer treatment during the study period was given for primary prophylaxis. A major reason for the decision to use g-csf appears to have been physician-perceived risk of febrile neutropenia. Delivery of g-csf by home-care nurses was well received by patients.

Abstract
BACKGROUND The pharmacoeconomics of the myeloid growth factors (MGFs) is an important topic that has received substantial attention in recent years. The use of the MGFs as primary prophylaxis to prevent febrile neutropenia (FN) has grown considerably over the past decade and professional guidelines regarding their use have broadened the settings in which these agents are indicated. Recent data also suggest a potential role for them in reducing infection-related and all-cause mortality. The cost and effectiveness of these agents will continue to gain visibility as companies pursue approval for biosimilar agents in the US, similar to their recent approval in Europe. OBJECTIVES The objective of this paper is to review the available pharmacoeconomic literature on the MGFs, which is particularly timely in light of the recent passage of healthcare reform and the increasing focus on cost control. The cost of treating cancer in the US is rising faster than the already rapid increase in overall medical expenditure. The clinical utility and cost effectiveness of supportive care measures in oncology must therefore be weighed carefully. This review focuses on the use of different formulations of MGFs for primary and secondary prophylaxis of chemotherapy-induced neutropenia. METHODS A MEDLINE search was performed to find studies that became available since the prior review of this topic was published in Pharmacoeconomics in 2003. RESULTS Acceptable cost-minimization estimates for primary prophylaxis with the MGFs in patients receiving cancer chemotherapy have been provided by several studies in the US. Of the commonly used agents in the US, pegfilgrastim appears to be superior to the currently recommended dose and schedule of filgrastim in terms of cost minimization, and primary prophylaxis appears to be less costly than secondary prophylaxis. However, the cost benefits of primary prophylaxis in Europe are not as pronounced as in the US, due to the lower costs of medical care. Data continue to emerge suggesting a decreased risk of early mortality from averted infections as well as the possibility of a disease-specific mortality benefit through maintaining the relative dose intensity of chemotherapy with MGF support. CONCLUSION This evidence will prove valuable in assessing the overall cost effectiveness and cost utility of the MGFs in patients receiving cancer chemotherapy.

Abstract
PURPOSE The 2006 American Society of Clinical Oncology (ASCO) guideline recommended primary prophylaxis (PP) with granulocyte colony-stimulating factor (G-CSF) instead of secondary prophylaxis (SP) for elderly patients with diffuse aggressive lymphoma receiving chemotherapy. We examined the cost-effectiveness of PP when compared with SP. METHODS We conducted a cost-utility analysis to compare PP to SP for diffuse aggressive lymphoma. We used a Markov model with an eight-cycle chemotherapy time horizon with a government-payer perspective and Ontario health, economic, and cost data. Data for efficacies of G-CSF, probabilities, and utilities were obtained from published literature. Probabilistic sensitivity analysis (PSA) was conducted. RESULTS The incremental cost-effectiveness ratio of PP to SP was $700,500 per quality-adjusted life-year (QALY). One-way sensitivity analyses (willingness-to-pay threshold = $100,000/QALY) showed that if PP were to be cost-effective, the cost of hospitalization for febrile neutropenia (FN) had to be more than $31,138 (2.5 × > base case), the cost of G-CSF per cycle less than $960 (base case = $1,960), the risk of first-cycle FN more than 47% (base case = 24%), or the relative risk reduction of FN with G-CSF more than 91% (base case = 41%). Our result was robust to all variables. PSA revealed a 10% probability of PP being cost-effective over SP at a willingness-to-pay threshold of $100,000/QALY. CONCLUSION PP is not cost-effective when compared with SP in this population. PP becomes attractive only if the cost of hospitalization for FN is significantly higher or the cost of G-CSF is significantly lower.

Abstract
OBJECTIVES We examined health care use in conjunction with primary prophylaxis use of colony stimulating factors (CSF) during patients' initial course of chemotherapy. METHODS This retrospective cohort study identified adults aged 25 years and older with a diagnosis of breast, colorectal, or nonsmall cell lung cancer between 2002 and 2005 from the Western Washington Surveillance Epidemiology and End Results Puget Sound registry. We linked these records to health insurance claims from four payers representing 75% of those insured in the state. Claims records were used to determine chemotherapy regimen type, CSF use, febrile neutropenia occurrences, and supportive care. Chemotherapy regimens were categorized as conferring high, intermediate, or low risk of myelosuppression according to the National Comprehensive Cancer Network guidelines. CSF use was described as primary prophylaxis, other, or none. Antibiotics and antifungal and antiviral agents per National Comprehensive Cancer Network guidelines for supportive care for cancer infection were categorized using Healthcare Common Procedure Coding System and National Drug Code assignments. RESULTS Use of CSF as primary prophylaxis is not significantly associated with a reduction in antibiotic use or inpatient or outpatient visits. Primary prophylactic CSF use was associated with less use of antiviral drugs. CONCLUSIONS CSF use is not associated with a reduction in health care use, with the exception of antiviral drug use. Given the expense associated with CSF use, pragmatic trials and additional research are needed to further assess the affects of CSF on health care use.

Prophylaxis of chemotherapy-induced febrile neutropenia with granulocyte colony-stimulating factors: where are we now? Support Care Cancer 2010; 18:529-41.

Abstract
Updated international guidelines published in 2006 have broadened the scope for the use of granulocyte colony-stimulating factor (G-CSF) in supporting delivery of myelosuppressive chemotherapy. G-CSF prophylaxis is now recommended when the overall risk of febrile neutropenia (FN) due to regimen and individual patient factors is ≥20%, for supporting dose-dense and dose-intense chemotherapy and to help maintain dose density where dose reductions have been shown to compromise outcomes. Indeed, there is now a large body of evidence for the efficacy of G-CSFs in supporting dose-dense chemotherapy. Predictive tools that can help target those patients who are most at risk of FN are now becoming available. Recent analyses have shown that, by reducing the risk of FN and chemotherapy dose delays and reductions, G-CSF prophylaxis can potentially enhance survival benefits in patients receiving chemotherapy in curative settings. Accumulating data from ‘real-world’ clinical practice settings indicate that patients often receive abbreviated courses of daily G-CSF and consequently obtain a reduced level of FN protection. A single dose of PEGylated G-CSF (pegfilgrastim) may provide a more effective, as well as a more convenient, alternative to daily G-CSF. Prospective studies are needed to validate the importance of delivering the full dose intensity of standard chemotherapy regimens, with G-CSF support where appropriate, across a range of settings. These studies should also incorporate prospective evaluation of risk stratification for neutropenia and its complications.

Abstract
PURPOSE OF REVIEW The present review updates treatment of neutropenia from articles published from January 2008 through April 2009. RECENT FINDINGS Chemotherapy-induced neutropenia occurs most commonly in the first cycle of treatment. Older patients, patients with multiple comorbidities, and those receiving more myelotoxic drugs are prone to develop neutropenia and its complications. Current guidelines recommend the prophylactic use of the myeloid growth factors for the first cycle of chemotherapy for patients with more than a 20% risk of febrile neutropenia. Meta analysis from randomized trials shows that granulocyte colony-stimulating factor prophylaxis is associated with patients receiving more intensive chemotherapy, having better survival, but also having a higher risk of secondary acute myeloid leukemia. Antibiotics are standard treatment of febrile neutropenia and are increasingly used for prophylaxis in 'low-risk' patients. SUMMARY The myeloid growth factor granulocyte colony-stimulating factor has radically changed our approach to the prevention of febrile neutropenia. Antibiotics remain the mainstay of treatment of febrile neutropenia.

Abstract
BACKGROUND AND SCOPE This article discusses health economic challenges of research and development, registration, pricing and reimbursement of biopharmaceuticals and biosimilars. A literature search was carried out of PubMed, Centre for Reviews and Dissemination databases, Cochrane Database of Systematic Reviews and EconLit up to March 2009. FINDINGS The development process of biopharmaceuticals is risky, lengthy, complex and expensive. Registration is complicated by the inherent variation between biopharmaceuticals. Also, as biopharmaceuticals are likely to be efficacious in a subgroup of the patient population, there is a need to select the most responsive target population and to identify biomarkers. To inform pricing and reimbursement decisions, the development process needs to collect comparative data to calculate the incremental cost effectiveness and budget impact of biopharmaceuticals. There is a role for innovative mechanisms such as risk-sharing arrangements to reimburse biopharmaceuticals. CONCLUSIONS Given that biosimilars are similar, but not identical to the reference biopharmaceutical, the development process needs to generate clinical trial data in order to gain marketing authorisation. From a health economic perspective, the question arises whether inherent differences between biopharmaceuticals and biosimilars produce differences in safety, effectiveness and costs: to date, this question is unresolved. The early inclusion of health economics in the process of developing biopharmaceuticals and biosimilars is imperative with a view to demonstrating their relative (cost) effectiveness and informing registration, pricing and reimbursement decisions.
