Abstract
BACKGROUND Oncology patients receiving chemotherapy are at a high risk for developing infections. Identifying factors that predict infection practices among these patients can help improve the quality of care provided. PURPOSE The purpose of this study was to evaluate the knowledge, attitudes, and practices related to infection prevention in oncology patients receiving chemotherapy. METHODS A cross-sectional study was conducted among 170 patients with cancer. RESULTS The majority of participants had a low to moderate level of knowledge, with high levels of attitude and practice related to infection prevention. Knowledge was a significant predictor of attitude and practice, while attitude was a predictor of infection prevention practices. Knowledge and attitude emerged as mutual predictors, which could explain 23% of the variation in practice toward infection prevention (R2 = 0.230, P = .00). CONCLUSIONS Findings indicated that both knowledge and attitude were powerful predictors of practice toward infection prevention.

Cost-effectiveness analysis of granulocyte colony-stimulating factors for the prophylaxis of chemotherapy-induced febrile neutropenia in patients with breast cancer in Taiwan. PLoS One 2024; 19:e0303294. [PMID: 38857244 PMCID: PMC11164394 DOI: 10.1371/journal.pone.0303294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 04/22/2024] [Indexed: 06/12/2024] Open
Abstract
OBJECTIVES To examine the cost-effectiveness of using granulocyte colony-stimulating factor (G-CSF) for primary or secondary prophylaxis in patients with breast cancer from the perspective of Taiwan's National Health Insurance Administration. METHODS A Markov model was constructed to simulate the events that may occur during and after a high-risk chemotherapy treatment. Various G-CSF prophylaxis strategies and medications were compared in the model. Effectiveness data were derived from the literature and an analysis of the National Health Insurance Research Database (NHIRD). Cost data were obtained from a published NHIRD study, and health utility values were also obtained from the literature. Sensitivity analyses were performed to assess the uncertainty of the cost-effectiveness results. RESULTS In the base-case analysis, primary prophylaxis with pegfilgrastim had an incremental cost-effectiveness ratio (ICER) of NT$269,683 per quality-adjusted life year (QALY) gained compared to primary prophylaxis with lenograstim. The ICER for primary prophylaxis with lenograstim versus no G-CSF prophylaxis was NT$61,995 per QALY gained. The results were most sensitive to variations in relative risk of febrile neutropenia (FN) for pegfilgrastim versus no G-CSF prophylaxis. Furthermore, in the probabilistic sensitivity analysis, at a willingness-to-pay threshold of one times Taiwan's gross domestic product per capita, the probability of being cost-effective was 88.1% for primary prophylaxis with pegfilgrastim. CONCLUSIONS Our study suggests that primary prophylaxis with either short- or long-acting G-CSF could be considered cost-effective for FN prevention in breast cancer patients receiving high-risk regimens.

Abstract
PURPOSE Adolescents and young adults (AYAs) experience vast symptom burden resulting from cancer treatment-related toxicities (TRTs). Evidence supports integrated exercise to mitigate several TRTs in other cohorts; however, evidence in AYAs is lacking. Conventional reporting of TRTs adopts a maximum grade approach failing to recognise the trajectory over time, of persistent, or lower grade toxicities. Alternatively, longitudinal analysis of toxicities over time (ToxT) may provide clinically meaningful summaries of this data. We evaluated the longitudinal impact of an exercise intervention on TRTs in AYAs undergoing cancer treatment. METHODS A prospective, randomised trial allocated participants to a 10-week exercise intervention (EG) or control group (CG) undergoing usual care. Detailed information on TRTs was collected throughout the intervention. All TRTs were graded per the Common Terminology Criteria for Adverse Events (CTCAE v5.0). RESULTS Forty-three (43) participants (63% male, mean age 21.1 years) were enrolled. When categorised to reflect the maximal worst grade experienced (Grade 0, Grade 1-2 and ≥ Grade 3), the CG reported an increased incidence of severe fatigue (≥ Grade 3) compared with the EG (p = 0.05). No other differences between groups were evident (p > 0.05). ToxT analysis of the four most common toxicities (fatigue, pain, nausea and mood disturbances) demonstrated no difference in the mean grade of each over time (p > 0.05). CONCLUSION A 10-week exercise intervention reduces the severity of fatigue in AYAs undergoing treatment. While the ToxT approach provided insight into the toxicity profile, adequately powered studies are needed to better understand these differences within a homogenous sample.

Pharmaceuticals (Basel) 2024; 17:484.

Abstract
Venetoclax is a Bcl-2 homology domain 3 (BH3) mimetic currently approved for the treatment of chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML) that has proven to be highly effective in reinstating apoptosis in leukemic cells through the highly selective inhibition of the anti-apoptotic protein B-cell lymphoma-2 (Bcl-2). Clinically, venetoclax has provided lasting remissions through the inhibition of CLL and AML blasts. However, this activity has often come at the cost of grade III/IV neutropenia due to hematopoietic cells' dependence on Bcl-2 for survival. As life-threatening infections are an important complication in these patients, an effective management of neutropenia is indispensable to maximize patient outcomes. While there is general consensus over dose reduction and scheduling modifications to minimize the risk of neutropenia, the impact of these modifications on survival is uncertain. Moreover, guidelines do not yet adequately account for patient-specific and disease-specific risk factors that may predict toxicity, or the role combination treatment plays in exacerbating neutropenia. The objective of this review is to discuss the venetoclax-induced mechanism of hematological toxicity, the potential predictive risk factors that affect patient vulnerability to neutropenia, and the current consensus on practices for management of neutropenia.

Abstract
Background Neutropenic sepsis is a common complication of systemic anticancer treatment. There is variation in practice in timing of switch to oral antibiotics after commencement of empirical intravenous antibiotic therapy. Objectives To establish the clinical and cost effectiveness of early switch to oral antibiotics in patients with neutropenic sepsis at low risk of infective complications. Design A randomised, multicentre, open-label, allocation concealed, non-inferiority trial to establish the clinical and cost effectiveness of early oral switch in comparison to standard care. Setting Nineteen UK oncology centres. Participants Patients aged 16 years and over receiving systemic anticancer therapy with fever (≥ 38°C), or symptoms and signs of sepsis, and neutropenia (≤ 1.0 × 109/l) within 24 hours of randomisation, with a Multinational Association for Supportive Care in Cancer score of ≥ 21 and receiving intravenous piperacillin/tazobactam or meropenem for < 24 hours were eligible. Patients with acute leukaemia or stem cell transplant were excluded. Intervention Early switch to oral ciprofloxacin (750 mg twice daily) and co-amoxiclav (625 mg three times daily) within 12-24 hours of starting intravenous antibiotics to complete 5 days treatment in total. Control was standard care, that is, continuation of intravenous antibiotics for at least 48 hours with ongoing treatment at physician discretion. Main outcome measures Treatment failure, a composite measure assessed at day 14 based on the following criteria: fever persistence or recurrence within 72 hours of starting intravenous antibiotics; escalation from protocolised antibiotics; critical care support or death. Results The study was closed early due to under-recruitment with 129 patients recruited; hence, a definitive conclusion regarding non-inferiority cannot be made. Sixty-five patients were randomised to the early switch arm and 64 to the standard care arm with subsequent intention-to-treat and per-protocol analyses including 125 (intervention n = 61 and control n = 64) and 113 (intervention n = 53 and control n = 60) patients, respectively. In the intention-to-treat population the treatment failure rates were 14.1% in the control group and 24.6% in the intervention group, difference = 10.5% (95% confidence interval 0.11 to 0.22). In the per-protocol population the treatment failure rates were 13.3% and 17.7% in control and intervention groups, respectively; difference = 3.7% (95% confidence interval 0.04 to 0.148). Treatment failure predominantly consisted of persistence or recurrence of fever and/or physician-directed escalation from protocolised antibiotics with no critical care admissions or deaths. The median length of stay was shorter in the intervention group and adverse events reported were similar in both groups. Patients, particularly those with care-giving responsibilities, expressed a preference for early switch. However, differences in health-related quality of life and health resource use were small and not statistically significant. Conclusions Non-inferiority for early oral switch could not be proven due to trial under-recruitment. The findings suggest this may be an acceptable treatment strategy for some patients who can adhere to such a treatment regimen and would prefer a potentially reduced duration of hospitalisation while accepting increased risk of treatment failure resulting in re-admission. Further research should explore tools for patient stratification for low-risk de-escalation or ambulatory pathways including use of biomarkers and/or point-of-care rapid microbiological testing as an adjunct to clinical decision-making tools. This could include application to shorter-duration antimicrobial therapy in line with other antimicrobial stewardship studies. Trial registration This trial is registered as ISRCTN84288963.

Abstract
Data about biosimilar Peg-filgrastim (bioPEG) in autologous stem cell transplant (ASCT) are still scarce. The aim of this study has been to assess efficacy and safety of bioPEG among lymphoma and myeloma patients undergoing ASCT, comparing these data with historical controls receiving other G-CSFs. Furthermore, an economic evaluation has been included to estimate the savings by using bioPEG. This is a prospective cohort study comparing lymphoma and myeloma patients undergoing ASCT and receiving bioPEG (n = 73) with three historical consecutive cohorts collected retrospectively who received other G-CSFs (Lenograstim - Leno - n = 101, biosimilar Filgrastim - bioFIL n = 392, and originator Peg-filgrastim - oriPEG n = 60). We observed a significantly shorter time to neutrophils and platelet engraftment (p < 0.001) in patients treated with bioPEG and oriPEG. Moreover, patients who received bioPEG showed a shorter hospitalization time (p < 0.001) and a lower transfusion need (p < 0.001). We did not observe any significant difference in terms of transplant-related mortality, mucositis, and diarrhea among the four groups. No serious adverse events were associated with bioPEG. Similar data were obtained after running a stratified analysis for lymphomas and myeloma separately conducted by using a propensity score matching. The average total cost per patient of bioPEG was € 18218.9 compared to € 23707.8, € 20677.3 and € 19754.9 of Leno, oriPEG, and bioFIL, respectively. In conclusion, bioPEG seems to be as effective as the originator and more effective than short-acting G-CSFs in terms of post-transplant engraftment in myeloma and lymphoma patients undergoing ASCT. Moreover, bioPEG was cost-effective when compared with the other G-CSFs.

Abstract
The White Blood Cell (WBC) count is one of the key parameters signaling the health of the immune system. Abnormal WBC counts often signal a systemic insult to the body such as an underlying infection or an adverse side effect to medication. Typically, the blood collected is sent to a central lab for testing, and results come back within hours, which is often inconvenient and may delay time-sensitive diagnosis or treatment. Here, we present the CytoTracker, a fully electronic, microfluidic based instant WBC analyzer with the potential to be used at point-of-care. The CytoTracker is a lightweight, portable, affordable platform capable of quantifying WBCs within minutes using only 50 μl of blood (approximately one drop of blood). In this study, we clinically evaluated the accuracy and performance of CytoTracker in measuring WBC and granulocyte counts. A total of 210 adult patients were recruited in the study. We validated the CytoTracker against a standard benchtop analyzer (Horiba Point of Care Hematology Analyzer, ABX Micros 60). Linear dynamic ranges of 2.5 k/μl- 35 k/μl and 0.6 k/μl- 26 k/μl were achieved for total WBC count and granulocyte count with correlation coefficients of 0.97 and 0.98. In addition, we verified CytoTracker's capability of identifying abnormal blood counts with above 90% sensitivity and specificity. The promising results of this clinical validation study demonstrate the potential for the use of the CytoTracker as a reliable and accurate point-of-care WBC analyzer.

Abstract
INTRODUCTION Trilaciclib was recently approved in the USA for reducing chemotherapy-induced myelosuppression (CIM) among adults with extensive-stage small cell lung cancer (ES-SCLC) when administered prior to chemotherapy. There is limited understanding of real-world outcomes of trilaciclib. METHODS A comprehensive literature review was conducted using a keyword search in the MEDLINE, Embase, and conference abstracts. Additional studies were identified through communications with the authors of relevant studies. Published and unpublished real-world studies of trilaciclib- and comparable non-trilaciclib-treated patients with ES-SCLC were included. Evidence on myelosuppressive hematologic adverse events (HAEs), cytopenia-related healthcare utilization, and other reported outcomes (e.g., hospitalizations, dose reduction, and treatment delay) were synthesized. If feasible, outcomes were compared qualitatively between the trilaciclib and historical reference groups, and between first-line trilaciclib initiators and the overall trilaciclib population. Weighted averages were estimated for selected outcomes using sample size as the weight. RESULTS The literature search identified five unique studies based on eight records-two included trilaciclib only, two non-trilaciclib only, and one both. In trilaciclib cohorts, the weighted average prevalence of grade ≥ 3 myelosuppressive HAEs in ≥ 1 lineage, ≥ 2 lineages, and all three lineages was 40.5%, 14.5%, and 7.5%, respectively. All rates were numerically lower compared to the historical non-trilaciclib cohorts (58.8%, 28.0%, 13.0% respectively). Cytopenia-related healthcare utilization was also lower in the trilaciclib cohorts. In general, first-line trilaciclib initiators had numerically lower myelosuppressive HAEs and cytopenia-related healthcare utilization than the overall trilaciclib patients. CONCLUSIONS The existing evidence suggests that trilaciclib may reduce single and multilineage grade ≥ 3 myelosuppressive HAEs and cytopenia-related healthcare utilization among patients with ES-SCLC in the real world. It is a promising new treatment for CIM prevention in ES-SCLC and may bring greater benefits to first-line trilaciclib initiators. Future studies are recommended to further evaluate the real-world effectiveness of trilaciclib.

Abstract
Telomerase RNA (TERC) has a noncanonical function in myelopoiesis binding to a consensus DNA binding sequence and attracting RNA polymerase II (RNA Pol II), thus facilitating myeloid gene expression. The CR4/CR5 domain of TERC is known to play this role, since a mutation of this domain found in dyskeratosis congenita (DC) patients decreases its affinity for RNA Pol II, impairing its myelopoietic activity as a result. In this study, we report that two aptamers, short single-stranded oligonucleotides, based on the CR4/CR5 domain were able to increase myelopoiesis without affecting erythropoiesis in zebrafish. Mechanistically, the aptamers functioned as full terc; that is, they increased the expression of master myeloid genes, independently of endogenous terc, by interacting with RNA Pol II and with the terc-binding sequences of the regulatory regions of such genes, enforcing their transcription. Importantly, aptamers harboring the CR4/CR5 mutation that was found in DC patients failed to perform all these functions. The therapeutic potential of the aptamers for treating neutropenia was demonstrated in several preclinical models. The findings of this study have identified two potential therapeutic agents for DC and other neutropenic patients.

Abstract
BACKGROUND Febrile Neutropenia (FN) caused by bacteria in cancer patients is associated with poor prognosis. The aim of this study was to determine the prevalence of FN and associated factors among cancer patients on chemotherapy at Ocean Road Cancer Institute (ORCI), Tanzania. METHODS A cross-sectional study was conducted from June to September 2019. Study participants were conveniently recruited. A desk review of participants medical records was performed. Standard microbiological procedures used to culture and identify the bacterial isolates from the positive blood cultures of participants that presented with FN. Kirby-Bauer disc diffusion was used to perform the antibiotics susceptibility testing. SPSS version 20.0 and MS Excel were used in data entry and analysis. Chi-Square was used as a measure of association between various factors and neutropenia. P-value less than 0.05 was considered statistically significant. RESULTS A total 213 participants were enrolled. Of these 76.1% were female. Most of the participants came from the Coast region. Majority of participants presented with breast Cancer (36.2%) and GIT (20.2%). The prevalence of FN and bacteremia was 5.6% and 35.3% respectively. Staphylococcus Aureus (60%) and Coagulase-Negative Staphylococci (40%) were the main isolates. Of the 6 isolates tested most were resistant to Co-Trimoxazole 4/6 (66.7%) and Doxycycline 3/6 (50%). FN was positively associated with chemotherapy regimen (P = 0.0001), platelets count (P = 0.0001) and use of G-CSF (P = 0.0001). CONCLUSION The prevalence of FN among the cancer patients on chemotherapy in Tanzania is low but associated with drug-resistant bacteria.

Abstract
Febrile neutropenia (FN) is one of the most important life-threatening complications in haemato-oncology. Our objective was to report all-cause mortality rates in patients ill with a hematological malignancy (HM) hospitalized with a first FN episode and to identify predictors for mortality. We conducted a historical retrospective cohort study of consecutive patients with an HM, >18 years of age, admitted between January 2012 and August 2018 for a first episode of FN. Data on all-cause mortality 12 months after admission for FN were obtained. The Kaplan-Meier curve was used to describe mortality during the follow-up period. Univariate and multivariable analyses identified predictors for 1,3 and 12-month mortality. One hundred and fifty-eight patients (mean age 69.5, 49.4% males) were included. Overall, 54 patients died (15.8%, 25.9%, and 34.1% died after 1, 3, and 12 months, respectively). Lower serum albumin, higher serum gamma-glutamyl transferase (GGT), lower estimated glomerular filtration rate (eGFR), older age, higher temperature, and lower absolute lymphocyte count at admission were independent predictors of all-cause mortality after 12 months. Further studies are needed to confirm our results and identify therapeutic strategies to improve survival.

Abstract
Chemotherapy is the standard of care for most malignancies. Its tumor debulking effect in adjuvant or neoadjuvant settings is unquestionable, although secondary effects have been reported that paradoxically promote metastasis. Chemotherapy affects the hematopoietic precursors leading to myelosuppression, with neutropenia being the main hematological toxicity induced by cytotoxic therapy. We used renal and lung murine tumor models metastatic to the lung to study chemotherapy-induced neutropenia (CIN) in the metastatic process. Cyclophosphamide and doxorubicin, two myelosuppressive drugs, but not cisplatin, increased the burden of artificial metastases to the lung, by reducing neutrophils. This effect was recapitulated by treatment with anti-Ly6G, the selective antibody-mediated neutrophil depletion that unleashed the formation of lung metastases in both artificial and spontaneous metastasis settings. The increased cancer dissemination was reversed by granulocyte-colony stimulating factor-mediated boosting of neutrophils in combination with chemotherapy. CIN affected the early metastatic colonization of the lung, quite likely promoting the proliferation of tumor cells extravasated into the lung at 24-72 hours. CIN did not affect the late events of the metastatic process, with established metastasis to the lung, nor was there any effect on the release of cancer cells from the primary, whose growth was, in fact, somewhat inhibited. This work suggests a role of neutrophils associated to a common cancer treatment side effect and claims a deep dive into the relationship between chemotherapy-induced neutropenia and metastasis.

Abstract
OBJECTIVE To examine the microbiological profile, sensitivity of organisms, treatment and outcomes of in-patients suffering from febrile neutropenia in a tertiary healthcare centre. METHODS Data was obtained from the Electronic Medical Health records in Aster Medcity, Cochin, IND. The study population included adult patients undergoing treatment for hematologic malignancies or solid tumors in the hospital between January 2021 and March 2023. Febrile neutropenia episodes were identified based on (1) absolute neutrophil count ≤1500 mm3, (2) at least a single recorded oral temperature of >38.0∘C (100.4∘F) sustained over a one-hour period. Febrile neutropenia consequences included ICU admission, length of ICU admission, and mortality. RESULTS Total 115 cases of febrile neutropenia were identified in the time period from January 2021 to March 2023. Organisms were isolated from 43% of all the cultures taken. The most common organism isolated was Klebsiella pneumoniae (32.81%), followed by Escherichia coli (29.69%) and Pseudomonas aeruginosa (10.94%). Other organisms that were also isolated were Candida albicans (3.13%), Aeromonas hydrophilia, Acinetobacter baumannii, Burkholderia cepacia, Enterobacter cloacae, Enterococcus faecium, Staphylococcus epidermidis, Staphylococcus hemolyticus, Streptococcus spp, and one case of Ralstonia mannitolytica. Multi-drug resistance (MDR) was seen in 33% of isolates and extensive-drug resistance was seen in 19% of isolates. E. coli showed the highest prevalence of antibiotic resistance with 68% growing MDR isolates and 16% growing XDR isolates. ICU stay was required in 34% of patients with a median duration of stay of three days. A mortality rate of 16.52% was seen, with 17.11% in hematological malignancies and 15.38% in solid tumors. CONCLUSIONS This study showed an increasing prevalence of Gram-negative bacterial infection in patients with febrile neutropenia. It also shows a high prevalence of antibiotic resistance in microbes in febrile neutropenia. Larger multi-hospital studies are required to better understand the microbiological profile of febrile neutropenia and identify the developing antimicrobial resistance trends.

Abstract
The majority of published findings on chemotherapy-induced febrile neutropenia (FN) are restricted to three ethnic groups: Asians, Caucasians, and African Americans. In this two-part study, we examined FN incidence and risk factors in Chinese, Malay, and Indian chemotherapy-treated breast cancer (BC) patients. Hospital records or ICD codes were used to identify patients with FN. In both the Singapore Breast Cancer Cohort (SGBCC) and the Joint Breast Cancer Registry (JBCR), the time of the first FN from the start of chemotherapy was estimated using Cox regression. Multinomial regression was used to evaluate differences in various characteristics across ethnicities. FN was observed in 170 of 1014 patients in SGBCC. The Cox model showed that non-Chinese were at higher risk of developing FN (HRMalay [95% CI]:2.04 [1.44-2.88], p < 0.001; HRIndian:1.88 [1.11-3.18], p = 0.018). In JBCR, FN was observed in 965 of 7449 patients. Univariable Cox models identified ethnicity, a lower baseline absolute neutrophil count, non-luminal A proxy subtypes, and anthracycline-containing regimens as risk factors. Disparities across ethnicities' risk (HRMalay:1.29 [1.07-1.54], p = 0.006; HRIndian:1.50 [1.19-1.88], p < 0.001) remained significant even after further adjustments. Finally, an age-adjusted multinomial model showed that Malays (p = 0.006) and Indians (p = 0.009) were significantly more likely to develop multiple episodes of FN during treatment. Ethnic differences in chemotherapy-induced FN among BC patients exist. Further studies can focus on investigating pharmacogenetic differences across ethnicities.

Abstract
PURPOSE OF REVIEW While chemotherapy treatment options for patients with solid and hematologic malignancies have dramatically improved over recent years, chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN) remain major barriers to delivering treatment at full doses and optimal timing. Despite concurrent advances in granulocyte colony-stimulating factor (G-CSF) administration, multiple barriers to the administration of and disparities in the access to these agents remain. The introduction of new, emerging agents, including biosimilars and novel therapies show promise in improving outcomes for CIN. RECENT FINDINGS The introduction of biosimilar filgrastim products has improved access to G-CSF administration by driving marketplace competition and has reduced costs for both patients and healthcare systems without sacrificing efficacy. Emerging therapies to address similar issues include long-acting G-CSF products, efbemalenograstim alfa and eflapegrastin-xnst, as well as agents with novel mechanisms of action, plinabulin and trilaciclib. These agents have shown efficacy and cost-saving benefits in certain populations and disease groups. SUMMARY Multiple emerging agents show promise in decreasing the burden of CIN. Use of these therapies will reduce access disparities and will improve outcomes for patients with cancer receiving cytotoxic chemotherapy. Many ongoing trials are underway to evaluate the roles of these agents for more widespread use.

Abstract
BACKGROUND Reduced relative dose intensity (RDI) of neoadjuvant chemotherapy (NACT) in patients with breast cancer may compromise treatment outcome and survival. We examined patient-related characteristics associated with treatment modifications and suboptimal RDI and tumour response in patients with breast cancer. METHODS In this observational study, electronic medical records were reviewed retrospectively for female patients with breast cancer scheduled for NACT at a university hospital in Denmark between 2017 and 2019. The RDI (ratio of delivered dose intensity in relation to standard dose intensity) was calculated. Multivariate logistic regression analyses examined associations of sociodemographics, general health and clinical cancer characteristics with dose reductions, dose delays, discontinuation of NACT and suboptimal RDI < 85%. RESULTS Among 122 included patients, 43%, 42% and 28% experienced dose reductions, dose delays ≥3 days and discontinuation, respectively. A total of 25% received an RDI < 85%. Comorbidity, taking long-term medications and being overweight were statistically significantly associated with treatment modifications, while age ≥ 65 years and comorbidity were associated with RDI < 85%. Around one third of all patients had radiologic (36%) or pathologic (35%) complete tumour response, with no statistically significant differences by RDI < or ≥85% irrespective of breast cancer subtype. CONCLUSIONS While most patients had RDI ≥85%, still one out of four patients received an RDI < 85%. Further investigations of possible supportive care initiatives to improve patients' treatment tolerability are needed, particularly among subgroups of older age or with comorbidity.

Abstract
Multiple myeloma (MM) is the main indication for autologous stem cell transplantation (ASCT). Novel supportive therapies (e.g., granulocyte colony-stimulating factor) have significantly improved post-ASCT-related mortality; however, data on biosimilar pegfilgrastim-bmez (BIO/PEG) in this setting is lacking. This prospective cohort study compared Italian patients with MM who received BIO/PEG post-ASCT with data collected retrospectively from historical control groups from the same center who received either filgrastim-sndz (BIO/G-CSF) or pegfilgrastim (PEG; originator). The primary endpoint was time to neutrophil engraftment (three consecutive days with an absolute neutrophil count ≥ 0.5 × 109/L). Secondary endpoints included incidence and duration of febrile neutropenia (FN). Of the 231 patients included, 73 were treated with PEG, 102 with BIO/G-CSF, and 56 with BIO/PEG. Median age was 60 years and 57.1% were male. Neutrophil engraftment was reached after a median of 10 days in the BIO/PEG and PEG groups and 11 days in the BIO/G-CSF group. Among patients who achieved neutrophil engraftment earlier than this (i.e., day 9), 58% (29/50) were on PEG; of those who achieved it later (i.e., day 11), 80.8% (59/73) were on BIO/G-CSF. FN incidence was higher with BIO/G-CSF (61.4%) versus PEG (52.1%) or BIO/PEG (37.5%) (p = 0.02 among groups). Patients on BIO/PEG had less frequent grade 2-3 diarrhea (5.5%) compared with BIO/G-CSF (22.5%) or PEG (21.9%); grade 2-3 mucositis was most frequent in the BIO/G-CSF group. In conclusion, pegfilgrastim and its biosimilar displayed an advantageous efficacy and safety profile compared with biosimilar filgrastim in patients with MM post-ASCT.

Abstract
AIMS Trilaciclib is a first-in-class, intravenous cyclin-dependent kinase 4/6 inhibitor that provides multilineage protection from chemotherapy-induced myelosuppression. This analysis aimed to characterize the population pharmacokinetics (PK) of trilaciclib, identify potential covariates influencing trilaciclib PK, and evaluate exposure-response relationships in extensive-stage small cell lung cancer (ES-SCLC) and triple-negative breast cancer (TNBC) trials. METHODS Population PK analysis was performed using data from healthy volunteers (n = 72), patients with ES-SCLC (n = 111) and patients with TNBC (n = 14). Exposure-response analyses were conducted to investigate the impact of trilaciclib exposure (AUC) on myeloprotective efficacy, antitumour efficacy and safety. Logistic regression and Cox regression models were used for binary and time-to-event endpoints, respectively. RESULTS Trilaciclib PK was described by a three-compartment model. Sex, body surface area, baseline albumin concentration and age were identified as significant covariates on trilaciclib PK but did not have clinically relevant impact on exposure. Based on exposure-response analyses, lower and higher exposures of trilaciclib at clinical doses (200-280 mg/m2 ) were associated with similar myeloprotective effects. Trilaciclib exposure did not impact the antitumour effects of chemotherapy. Higher exposure to trilaciclib was associated with higher probabilities of headache, phlebitis/thrombophlebitis and injection site reactions. CONCLUSION No dose adjustments are required based on the covariates tested. Trilaciclib resulted in optimal myeloprotective effects with no impact on antitumour effects of chemotherapy. However, higher exposure increased the probabilities of adverse events. The data further support selection of the recommended phase 2 dose (trilaciclib 240 mg/m2 ).

Abstract
Neutropenic fever (NF) is an oncologic emergency for which expert consensus recommends that anti-pseudomonas antibiotics be administered within 60 minutes of detection. This study investigated whether delays in time to antibiotics (TTA) impacted overall survival (OS) for patients with hematological malignancies who developed inpatient NF via a retrospective cohort study of 187 de novo NF cases categorized by TTA (<1, 1-2, 2-3, 3-4 and >4 hours). OS at 180 days post-NF episode was compared using Kaplan-Meier estimates and multivariable Cox proportional hazards model. TTA did not significantly affect OS (P = 0.420). Patients with Charleston Comorbidity Indexes ≥3, a measure of overall health, had higher hazard (hazard ratio [HR] = 2.728, 95% confidence interval, 1.265-5.882, P = 0.010). TTA delays in the hospital may not be long enough to cause significant patient harm. Larger studies may be needed to detect small, but significant mortality differences.

Abstract
Treatment with bevacizumab is known to cause adverse events such as proteinuria and hypertension, amongst others. However, while bevacizumab-induced hypertension has been linked to increased overall survival (OS), data on proteinuria are controversial. We performed a retrospective analysis to observe the influence of adverse events developed during treatment with bevacizumab and chemotherapy on the OS in patients with metastatic colorectal cancer (mCRC). Kaplan–Meier and log-rank analyses were used to assess differences in OS, and hazard ratios (HR) were estimated using Cox models. Out of the 3497 mCRC patients admitted to our center between 2014 and 2019, 150 met the criteria for inclusion in our analysis. Out of these, 50.7% experienced proteinuria and had reached a longer OS (40 versus 25 months, p = 0.015) and progression-free survival (15 versus 12 months, p = 0.039). The following groups were identified as having a lower risk of death: patients with proteinuria (HR 0.589; 95% CI 0.402–0.863; p = 0.007), one metastatic site (HR 0.533; 95% CI 0.363–0.783; p = 0.001), and non-metastatic stage at diagnosis (HR 0.459; 95% CI 0.293–0.720; p = 0.001). Patients with anemia and diabetes had an increased risk of death. Proteinuria emerges as a useful prognostic factor in mCRC patients undergoing bevacizumab-based systemic therapy, and it could be easily integrated into the decision-making process, thus allowing physicians to further individualize systemic treatments.

Abstract
The importance of the tumor microenvironment (TME) in dynamically regulating cancer progression and influencing the therapeutic outcome is widely accepted and appreciated. Several therapeutic strategies to modify or modulate the TME, like angiogenesis or immune checkpoint inhibitors, showed clinical efficacy and received approval from regulatory authorities. Within recent decades, new promising strategies targeting myeloid cells have been implemented in preclinical cancer models. The predominance of specific cell phenotypes in the TME has been attributed to pro- or anti-tumoral. Hence, their modulation can, in turn, alter the responses to standard-of-care treatments, making them more or less effective. Here, we summarize and discuss the current knowledge and the correlated challenges about the tumor-associated macrophages and neutrophils targeting strategies, current treatments, and future developments.

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
BACKGROUND We aimed to evaluate relationships between clinical outcomes and explanatory variables by network clustering analysis using data from a post marketing surveillance (PMS) study of castration-resistant prostate cancer (CRPC) patients. METHODS The PMS was a prospective, multicenter, observational study of patients with metastatic, docetaxel-refractory CRPC treated with cabazitaxel in Japan after its launch in 2014. Graphical Markov (GM) model-based simulations and network clustering in 'R' package were conducted to identify correlations between clinical factors and outcomes. Factors shown to be associated with overall survival (OS) in the machine learning analysis were confirmed according to the clinical outcomes observed in the PMS. RESULTS Among the 660 patients analyzed, median patient age was 70.0 years, and median OS and time-to-treatment failure (TTF) were 319 and 116 days, respectively. In GM-based simulations, factors associated with OS were liver metastases, performance status (PS), TTF, and neutropenia (threshold 0.05), and liver metastases, PS, and TTF (threshold 0.01). Factors associated with TTF were OS and relative dose intensity (threshold 0.05), and OS (threshold 0.01). In network clustering in 'R' package, factors associated with OS were number of treatment cycles, discontinuation due to disease progression, and TTF (threshold 0.05), and liver and lung metastases, PS, discontinuation due to adverse events, and febrile neutropenia (threshold 0.01). Kaplan-Meier analysis of patient subgroups demonstrated that visceral metastases and poor PS at baseline were associated with worse OS, while neutropenia or febrile neutropenia and higher number of cabazitaxel cycles were associated with better OS. CONCLUSIONS Neutropenia may be a predictive factor for treatment efficacy in terms of survival. Poor PS and distant metastases to the liver and lungs were shown to be associated with worse outcomes, while factors related to treatment duration were shown to positively correlate with better OS.

Abstract
AIMS Chemotherapy-induced myelosuppression, which commonly exhibits as neutropenia, anemia, or thrombocytopenia, represents a substantial burden for patients with cancer that affects health-related quality of life and increases healthcare resource utilization (HCRU). We evaluated the burden of myelosuppression among chemotherapy-treated patients with small cell lung cancer (SCLC) using real-world data from community cancer care providers in the Western United States. MATERIALS AND METHODS This was a retrospective, observational analysis of electronic medical records (EMRs) from Providence St. Joseph Health hospital-associated oncology clinics between January 2016 and December 2019. Patient demographics were assessed from the date of first SCLC diagnosis in adult patients with chemotherapy-induced grade ≥3 myelosuppression in first-line (1L) or second-line-and-beyond (2L+) treatment settings. Myelosuppressive adverse events (AEs), treatment patterns, and HCRU were assessed from the date of chemotherapy initiation (index date) until 12 months, date of the last visit, date of death, or study end, whichever occurred earliest. RESULTS Of 347 eligible patients with SCLC who had received chemotherapy (mean age 66; 49% female), all had received at least 1L treatment, and 103 (29.7%) had a 2L + treatment recorded within the EMR during the study period. Of 338 evaluable patients with longitudinal laboratory data, 206 (60.9%) experienced grade ≥3 myelosuppressive AEs, most commonly neutropenia, anemia, and thrombocytopenia (44.9, 41.1, and 25.4 per 100 patients, respectively). Rates of granulocyte colony-stimulating factor use and red blood cell transfusions were 47.0 and 41.7 per 100 patients, respectively. There was a trend toward increasing the use of supportive care interventions and visits to inpatient and outpatient facilities in patients with myelosuppressive AEs in more than one cell lineage. CONCLUSIONS Chemotherapy-induced myelosuppression places a substantial real-world burden on patients with SCLC in the community cancer care setting. Innovations to protect bone marrow from chemotherapy-induced damage have the potential to reduce this burden.

[PMID: 36334157 PMCID: PMC9715510 DOI: 10.1007/s00520-022-07430-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 10/23/2022] [Indexed: 11/08/2022]
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 Febrile neutropenia (FN) is a life-threatening complication of Docetaxel-based chemotherapy regimens (DBRs). Prophylactic granulocyte-colony stimulating factor (G-CSF) can reduce the risk of FN. This study investigated the effect of G-CSF on FN in patients receiving DBRs for breast cancer. METHODS Patients treated between 2015 and 2017 were identified from the hospital's pharmacy database and their medical records were examined retrospectively. Data from patients' first four cycles of DBR were collected. FN rate, FN associated length of hospital stay (FN-LOS), and chemotherapy dose modification/delay due to FN were compared between patients who did (G-CSF group) or did not (non-GCSF group) receive prophylactic G-CSF. RESULTS Of the 276 included patients, 83.3% received a DBR as adjuvant or neoadjuvant therapy, and 50% received docetaxel as combination therapy. Prophylactic G-CSF was administered with the first cycle of a DBR in 69.9% of patients who were significantly less likely to experience FN compared to the non-G-CSF group (6.2% vs. 15.7%; odds ratio: 0.36 [95% CI: 0.16-0.82]; p = 0.020). Collectively and after the 4 DBR treatment cycles, FN rate (4.8 vs. 8.5; odds ratio: 0.54 [95% CI: 0.30-0.97]; p = 0.043) and the mean FN-LOS (3.55 vs. 5.28 days; t = -2.22; p = 0.037) were reduced in the G-CSF group. There was no difference in DBR dose delay/reduction between both groups in cycles 2-4. CONCLUSION In patients receiving DBRs for breast cancer, prophylactic G-CSF significantly reduced both the rate of FN and duration of hospitalization for FN.

Exploratory composite endpoint demonstrates benefit of trilaciclib across multiple clinically meaningful components of myeloprotection in patients with small cell lung cancer. Int J Cancer 2021; 149:1463-1472. [PMID: 34109630 PMCID: PMC8457063 DOI: 10.1002/ijc.33705] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 05/14/2021] [Accepted: 06/01/2021] [Indexed: 11/07/2022]
Abstract
Chemotherapy-induced myelosuppression is an acute, dose-limiting toxicity of chemotherapy regimens used in the treatment of extensive-stage small cell lung cancer (ES-SCLC). Trilaciclib protects haematopoietic stem and progenitor cells from chemotherapy-induced damage (myeloprotection). To assess the totality of the myeloprotective benefits of trilaciclib, including analysis of several clinically relevant but low-frequency events, an exploratory composite endpoint comprising five major adverse haematological events (MAHE) was prospectively defined: all-cause hospitalisations, all-cause chemotherapy dose reductions, febrile neutropenia (FN), prolonged severe neutropenia (SN) and red blood cell (RBC) transfusions on/after Week 5. MAHE and its individual components were assessed in three randomised, double-blind, placebo-controlled Phase 2 trials in patients receiving a platinum/etoposide or topotecan-containing chemotherapy regimen for ES-SCLC and in data pooled from the three trials. A total of 242 patients were randomised across the three trials (trilaciclib, n = 123; placebo, n = 119). In the individual trials and the pooled analysis, administering trilaciclib prior to chemotherapy resulted in a statistically significant reduction in the cumulative incidence of MAHE compared to placebo. In the pooled analysis, the cumulative incidences of all-cause chemotherapy dose reductions, FN, prolonged SN and RBC transfusions on/after Week 5 were significantly reduced with trilaciclib vs placebo; however, no significant difference was observed in rates of all-cause hospitalisations. Additionally, compared to placebo, trilaciclib significantly extended the amount of time patients remained free of MAHE. These data support the myeloprotective benefits of trilaciclib and its ability to improve the overall safety profile of myelosuppressive chemotherapy regimens used to treat patients with ES-SCLC.

Abstract
INTRODUCTION A decrease in relative-dose intensity (RDI) of chemotherapy has been shown to be associated with poor patient outcomes in solid tumors and non-Hodgkin's lymphoma. The actual delivered chemotherapy dose received by patients can be influenced by dose reductions and treatment delays, often due to toxicities, most commonly chemotherapy-induced neutropenia (CIN). AREAS COVERED We review seminal evidence and more recent studies that have shown an association between higher RDI and improved patient survival. A smaller number of studies has shown no association between RDI and outcomes. These differences may be due to study limitations, including low power, differences in patient and disease characteristics, or the chemotherapeutic regimen. We describe guidelines recommendations to prevent and treat CIN with granulocyte-colony stimulating factor (G-CSF) and describe novel approaches to prevent neutropenia that are being developed that may provide greater value and be associated with fewer adverse events than standard G-CSF options. EXPERT OPINION Maintaining RDI is important to ensure optimal patient outcomes. This can be achieved through the proper administration of G-CSF prophylaxis and treatment. Newer agents in development to treat and/or prevent CIN are entering regulatory review and may potentially change the treatment landscape for CIN in the future.

Abstract
Eribulin is one of the few recommended chemotherapies for locally advanced breast cancer (LABC) or metastatic breast cancer (MBC). We systematically searched MEDLINE Ovid, Cochrane Library, IPA, CINAHL, Web of Science and ProQuest Dissertations for studies evaluating eribulin versus non-eribulin regimens in LABC/MBC till January 15, 2021. Primary effectiveness and safety outcomes were overall survival (OS) and adverse events (AE), respectively. Hazard ratios (HR) and relative risks (RR) with 95 % confidence intervals (CIs) were calculated using fixed or random-effects meta-analyses. Of 1183 publications identified, 13 studies were included in this review. Eribulin based therapy showed significantly increased OS [HR (95 % CI) = 0.77 (0.67-0.88)] compared to non-eribulin in both main and sensitivity analyses, as well as subgroup analyses according to receptor expression and line of therapy. Incidence of all-grade neutropenia was the only significant AE in eribulin than non-eribulin groups. Eribulin has a manageable toxicity profile and provides significant survival benefit in LABC/MBC patients.

A Community Hospital-Based Study: A Prespecified Neutrophil Count with Adjuvant mFOLFOX6 Associated with Increased Delays, Increased G-CSF Use, and Reduced Dose Intensity. Cancer Manag Res 2021; 13:4087-4094. [PMID: 34040446 PMCID: PMC8141389 DOI: 10.2147/cmar.s307713] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 04/28/2021] [Indexed: 12/20/2022] Open
Abstract
Purpose To look at how the absolute neutrophil count (ANC) is used by community oncologists as the main factor in ordering adjuvant mFOLFOX6 for colorectal cancer. This study reports on how this decision impacts chemotherapy delays, effects received dose intensity (RDI), and increases the use of granulocyte-colony-stimulating factor (G-CSF). Methods A retrospective chart review was conducted for all patients receiving adjuvant mFOLFOX6 for colorectal cancer at a two-site community hospital in Toronto, Ontario, Canada, between July 2013 and March 2019. Seven physicians treated 140 patients, who made 1636 clinic visits to receive 1461 cycles of prescribed chemotherapy. Results The mean ANC per physician associated with a decision to give chemotherapy ranged from 1.05×109/L (95% CI 0.98-1.13×109/L) to 1.5x109/L with a decision to delay if the ANC was lower. Subsequent cycles were then supported by G-CSF with very similar ANC decision levels for dose delay. Physicians were more likely to prescribe chemotherapy with higher pretreatment ANC, r=0.3 (p<0.000). G-CSF was used in 24.6% of cycles and usage had grown to 44.2% by the 12th cycle; physician use ranged from 0.36% to 54.2% of cycles. Secondary prophylaxis was the indication in 94.7% of cases. There was an inverse relationship between the frequency of G-CSF use and the RDI of continuous infusion 5FU, r=-0.26 (p<0.001). There were delays for 8.8% of visits for cycles not supported by G-CSF and, surprisingly, 15.9% of visits for cycles supported by G-CSF. Neutropenia caused 61.6% of delays for chemotherapy cycles not supported by G-CSF and 44.1% for cycles supported by G-CSF. Conclusion Physicians required a pretreatment ANC of 1.05-1.5×109/L before prescribing mFOLFOX6 chemotherapy. When ANC was low, a dose delay and secondary prophylaxis with G-CSF failed to consistently achieve the much sought after ANC. This then caused more delay, reduced RDI and increased expense for both patients and the system. Fewer delays, less G-CSF and increased RDI would have resulted with reduced reliance on ANC and adoption of chemotherapy dose reduction.

Abstract
OBJECTIVES Few studies have investigated factors influencing the efficacy of chemotherapy in older patients with cancer. This study aimed to evaluate the usefulness of G8, geriatric assessment (GA), and factors measured in general clinical practice for evaluating progression-free survival (PFS) of first-line palliative chemotherapy in older patients with advanced gastrointestinal cancer. MATERIALS AND METHODS This was a prospective observational study of older patients (age ≥ 70 years) with advanced gastrointestinal cancer. The modified cut-off value of G8 was determined by referring to two or more abnormal GA conditions. The usefulness of baseline GA and G8 (conventional and modified cut-off value) was assessed according to the efficacy (PFS and disease control rate) of the administered first-line palliative chemotherapy. RESULTS Overall, 93 patients were evaluated between March 2017 and February 2019. A modified G8 cut-off value of ≤12 had a sensitivity and specificity of 68.9% and 46.9%, respectively. PFS was significantly prolonged in the patients with G8 > 12, serum albumin ≥3.5 g/dl, and in whom grade ≥ 3 adverse events occurred. There was no significant difference in the PFS between monotherapy and combination therapy. GA was not useful for predicting PFS prolongation or the occurrence of serious adverse events in first-line treatment. CONCLUSION Among older patients with advanced gastrointestinal cancer who receive first-line chemotherapy, a modified G8 cut-off value of 12 points, occurrence of grade 3 or higher adverse events, albumin levels, rather than age or performance status were predictors of PFS prolongation.

Abstract
Background A classification tree was used to analyze background factors for granulocyte colony-stimulating factor (G-CSF) preparation selection for febrile neutropenia (FN) prophylaxis in Japanese patients with non-Hodgkin B-cell lymphoma receiving the first R-CHOP cycle. Methods This was a subanalysis of the retrospective observational study STOP FN in NHL 2 (UMIN000029534). Patient characteristics, changes in neutrophil count, incidence and severity of neutropenia, and risk factors for dose reduction/delay of R-CHOP were assessed by G-CSF formulation. Results Among 234 patients in cycle 1, 25.6% received no G-CSF preparation, 52.1% received daily G-CSF, and 22.2% received pegfilgrastim. Pegfilgrastim use was most frequent among patients aged ≥ 80 years, while that of daily G-CSF was most frequent in patients with lymphocyte count (LC) < 1000 cells/μL. Changes in neutrophil count were more marked with pegfilgrastim compared with daily G-CSF and no G-CSF. Relevant factors for G-CSF preparation selection in the first R-CHOP cycle were age ≥ 80 years and LC < 1000 cells/μL; for chemotherapy dose reduction were FN onset in cycle 1 and female sex; and for dose delay was hemoglobin (< 12 g/dL). After cycle 2 and onward, pegfilgrastim use increased markedly (72.6%) compared with cycle 1 (22.2%), with significantly greater proportions continuing pegfilgrastim use and switching from daily G-CSF. Conclusion Relevant factors for G-CSF preparation selection were age ≥ 80 years and LC < 1000 cells/μL. The use of pegfilgrastim increased markedly after cycle 2. These results may be useful for selecting appropriate G-CSF preparations in the first R-CHOP cycle.

Abstract
Management of febrile neutropenia (FN) is an integral part of supportive care for patients undergoing cancer treatment. The NCCN Guidelines for Hematopoietic Growth Factors provide suggestions for appropriate evaluation, risk determination, prophylaxis, and management of FN. These NCCN Guidelines are intended to guide clinicians in the appropriate use of growth factors for select patients undergoing treatment of nonmyeloid malignancies. These NCCN Guidelines Insights highlight important updates to the NCCN Guidelines regarding the incorporation of newly FDA-approved granulocyte-colony stimulating factor biosimilars for the prevention and treatment of FN.

Objectives: This study evaluated the effect of lipegfilgrastim, a glycopegylated granulocyte-colony stimulating factor, used as primary (PP) or secondary prophylaxis (SP) on chemotherapy (CT) treatment modifications, as well as the incidence of CT-induced neutropenic events in adult patients receiving cytotoxic CT with or without biological therapy (BT) for solid and hematological tumors, in routine clinical practice. Other objectives were to characterize the population of lipegfilgrastim-treated cancer patients and safety assessment. Methods: This phase 4, prospective, observational study was conducted at 15 centers from Belgium and Luxembourg, between 2015 and 2017. Results: Of 139 patients, 82.7% had breast cancer and 54.7% were treated with dose-dense regimens. Most received lipegfilgrastim as PP (82.0%) and were at high-risk of febrile neutropenia (FN) (68.3%). FN and grade III/IV neutropenia were reported for 7.9% and 22.3% patients. Among 123 evaluated patients, CT/BT dose modifications were recorded for 33.3% (PP) and 52.4% (SP) of patients receiving lipegfilgrastim; dose reductions, followed by dose delays, were more frequent than omissions. Among 45 patients with dose modifications, FN was reported for 8.8% and 9.1% patients and grade IV neutropenia for 17.6% and 18.2% of patients when lipegfilgrastim was applied for PP and SP, respectively. Adverse events related to lipegfilgrastim occurred for 55 (39.6%) patients; bone pain and back pain were more frequent. Lipegfilgrastim-related serious adverse events were reported for 9 (6.5%) patients. Conclusion: Use of lipegfilgrastim in real-world settings resulted in limited CT dose modifications and low incidences of neutropenic events, with no new safety concerns arising.

Abstract
BACKGROUND Despite granulocyte colony-stimulating factor (GCSF) is widely used in clinical, cancer chemotherapy induced neutropenia (CCIN) infection and infection-related mortality is high for lack of functionally mature neutrophils. Generating functional neutrophils is new therapeutic approaches to reduce CCIN-associated infection and mortality. Saikosaponin a (SSA) is one of the major bioactive components of Radix Bupleuri (RB) and exerts immunoregulatory effects. PURPOSE The present study aims to investigate the efficacy and mechanism of SSA in CCIN therapy. METHODS SSA was applied both in vitro and in vivo to assess the efficacy of CCIN therapy. The differentiation of neutrophils was measured by Nitroblue tetrazolium (NBT) reduction assay and Giemsa staining assay. The neutrophil differentiation related real-time transcription factors were detected by quantitative PCR (RT-qPCR) and Western Blot. Bacteria killing assay was used to assess the ability of fighting infection. Network pharmacology was employed to explore the mechanism network, and the predicted pathways were validated by Western Blot. RESULTS We found that SSA contributed to generate functional mature neutrophils which capable of fighting infection both in vitro and in vivo. Network pharmacology prediction showed 55 pathways were predicted involved in SSA against CCIN. Further validation showed that CBL-ERK1/2 pathway was activated by SSA, which could upregulate PU.1 and CEBPβ expression leading to neutrophil differentiation. CONCLUSIONS Our findings suggest a natural regimen SSA regenerates microbicidal neutrophils to effectively reduce CCIN-associated infection via activating CBL-ERK1/2 pathway, providing a rationale for future therapeutic approaches.

Abstract
INTRODUCTION Granulocyte colony-stimulating factors are used in medical oncology for the prevention of neutropenia. On-body injectors (OBI) have an advantage over the traditional injection (TI) method of not requiring a second visit to the clinic, but these devices are subject to failure. The objective of this study was to assess the efficacy of OBIs in the real-world. METHODS Women with breast cancer diagnosed between June 2015 and June 2016 treated with cytotoxic chemotherapy and a granulocyte colony-stimulating factor were retrospectively identified from the medical records of Henry Ford Hospital. The primary outcome was the incidence of severe neutropenia (SN), defined as an absolute neutrophil count (ANC) ≤500. Secondary outcomes included incidence of neutropenia (ANC ≤ 1500), neutropenic fever, and mortality. A secondary analysis of the data was performed to identify predictors of SN. RESULTS A total of 837 cycles of chemotherapy were analyzed. The OBI was used in 395 cycles and the TI in 442. The OBI group had patients that were older, had higher baseline ANC, and were more often white. The incidences of SN, neutropenic fever and neutropenia were not different between groups. Patients with a lower baseline ANC and white ethnicity were at a higher risk for SN. AC (doxorubicin and cyclophosphamide) was the most commonly used chemotherapy regimen (38% of total cycles). CONCLUSIONS There was no difference in the efficacy of the OBI and TI methods for preventing SN, neutropenic fever and neutropenia.

Abstract
BACKGROUND Although hematologic review criteria for general hospitals have been established, they may be insufficient for cancer hospitals. This study aimed to establish the appropriate review criteria for hematology analyzers in cancer hospitals. METHODS A total of 1003 samples from our hospital were randomly selected for blood smear preparation and microscopic review. The review criteria of the International Consensus Group for Hematology Review (ICGH) and Chinese consensus group were used to obtain the review, true-negative (TN), true-positive (TP), false-negative (FN), and false-positive (FP) rates, as well as the triggered rules. Our review criteria were established by comparing flag or numeric value information of TP and FP samples, adjusting rules to obtain better efficiency, a low slide review rate, and an acceptable FN rate. RESULTS Overall, 197 (19.64%) samples showed positive smear findings. Compared to the ICGH criteria, the slide review rate of the newly established criteria declined from 51.25% to 39.28%, and the TP and TN rates increased from 17.85% and 46.06% to 23.13% and 55.83%, respectively. The FN rate of the newly established criteria was 3.69%. Another set of samples used to validate the newly established criteria yielded the review, FN, and FP rates as 33.49%, 1.86%, and 25.58%, respectively. CONCLUSION The newly established review criteria for hematology analyzers enabled the prompt identification, smear, and further verification of doubtful specimens, without a significant increase in the workload, thus improving the efficiency of the review process. This study provided data support for other cancer hospitals to establish review criteria.

Abstract
Polymer conjugation can be considered one of the leading approaches within the vast field of nanotechnology-based drug delivery systems. In fact, such technology can be exploited for delivering an active molecule, such as a small drug, a protein, or genetic material, or it can be applied to other drug delivery systems as a strategy to improve their in vivo behavior or pharmacokinetic activities such as prolonging the half-life of a drug, conferring stealth properties, providing external stimuli responsiveness, and so on. If on the one hand, polymer conjugation with biotech drug is considered the linchpin of the protein delivery field boasting several products in clinical use, on the other, despite dedicated research, conjugation with low molecular weight drugs has not yet achieved the milestone of the first clinical approval. Some of the primary reasons for this debacle are the difficulties connected to achieving selective targeting to diseased tissue, organs, or cells, which is the main goal not only of polymer conjugation but of all delivery systems of small drugs. In light of the need to achieve better drug targeting, researchers are striving to identify more sophisticated, biocompatible delivery approaches and to open new horizons for drug targeting methodologies leading to successful clinical applications.

Abstract
Purpose The regimen including concurrent docetaxel, doxorubicin, and cyclophosphamide (TAC) has been categorized as an important risk factor for febrile neutropenia (FN). This comparative study examined the clinical impact of long-acting granulocyte colony-stimulating factor (G-CSF) (pegfilgrastim) during adjuvant TAC chemotherapy in Korean patients with advanced breast cancer. Methods We analyzed data from 239 patients who received 6 cycles of adjuvant TAC chemotherapy. We categorized patients into 2 groups according to the use of primary prophylactic pegfilgrastim and compared the incidence and risk of FN, hospital care costs, and survival in the 2 groups. Results The incidence of FN decreased from 54.2% to 21.2% in all patients, after the use of pegfilgrastim. The analysis of a total of 1,432 chemotherapy cycles showed that the incidence of FN decreased from 36.1% to 9.1% after the use of pegfilgrastim. Moreover, the decrease in the incidence of FN with the use of pegfilgrastim resulted in a significant decrease in the mean duration of neutropenia (4.15 to 1.29 days), the risk of hospitalization (99.5% to 29.7%) and the mean total hospital care cost (USD 3,038 to USD 2,347). High relative dose intensity (RDI) in patients treated with pegfilgrastim than in those not treated with pegfilgrastim (99.18% vs. 93.85%) was associated with a better overall survival (p = 0.033). Conclusions The use of pegfilgrastim during adjuvant TAC chemotherapy was significantly associated with a decrease in the incidence and risk of FN, hospital care costs, and risk of death compared to the use of adjuvant TAC without primary prophylaxis.

Abstract
BACKGROUND PEGylated granulocyte colony-stimulating factor (G-CSF) is a safe alternative to G-CSF to improve chemotherapy-induced neutropenia (CIN). This superiority has resulted in its increased use by physicians; however, the superiority of PEGylated G-CSF for CIN in breast cancer has not been conclusively determined. OBJECTIVES To assess the superiority of PEGylated G-CSF for CIN in breast cancer in terms of effectiveness and safety via a systematic review and meta-analysis. METHODS A literature search in PubMed, Embase, Cochrane Library, and Web of Science was performed for eligible studies published from database inception to December 2019. All studies comparing PEGylated G-CSF and G-CSF for CIN of breast cancer were reviewed. After literature selection, data extraction and quality assessment were performed by two reviewers independently. Meta-analysis was conducted using Revman, version 5.2. RESULTS Nine randomized controlled trials were finally identified. The publication bias of these studies was acceptable. For the endpoint of effectiveness, analysis of the incidence/duration of grade ≥ 3 neutropenia, the duration of grade 4 neutropenia, the incidence of febrile neutropenia (FN), and the time to absolute neutrophil count recovery showed no advantage of PEGylated G-CSF over G-CSF for CIN of breast cancer (P > 0.05), with the premise of a sufficient dose of G-CSF according to the guidelines. No significant differences in grade 4 adverse events were observed between the groups (P = 0.29), and PEGylated G-CSF did not increase the incidence of skeletal and/or muscle pain compared with G-CSF (P = 0.32). CONCLUSION PEGylated G-CSF was as effective and safe as G-CSF to reduce CIN in breast cancer but did not show an obvious superiority. However, in clinical practice, PEGylated G-CSF has an obvious advantage in terms of convenience, which could improve patient's quality of life.

Abstract
Simple Summary Because FOLFIRINOX shows high prevalence of hematologic toxicity, it is meaningful to investigate of usefulness of primary G-CSF prophylaxis in metastatic pancreatic cancer patients. In this retrospective study, a total of 165 patients were divided into G-CSF user group (n = 57) and non-user group (n = 105). Baseline characteristics were not significantly different between two groups, which included initial absolute neutrophil counts and metastatic burden. Primary G-CSF prophylaxis reduced the risk of neutropenia (55.6% to 31.6%, p = 0.003) and febrile neutropenia (18.5% to 1.8%, p = 0.002) and improved OS (8.8 to 14.7 months; hazard ratio (HR): 1.766, 95% CI: 1.257–2.481, p = 0.001). When administering FOLFIRINOX for MPC, primary G-CSF prophylaxis could be rationalized to reduced AEs and improve survival, and more prospective studies are needed. Abstract Although FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) has been proven efficacious in metastatic pancreatic cancer (MPC), physicians hesitate to administer it due to its hematologic toxicities. We investigated the usefulness of primary granulocyte colony-stimulating factor (G-CSF) prophylaxis. We reviewed electronic medical records of MPC patients with good performance status who were administered FOLFIRINOX as the first-line treatment from 2011 to 2017. The patients were divided into primary G-CSF prophylaxis users (group A) and non-users or therapeutic/secondary users (group B). Cumulative relative dose (cRDI), adverse effects (AEs), and overall survival (OS) were compared. A total of 165 patients (group A (57) vs. group B (108)) were investigated. Intergroup differences in baseline characteristics were not significant, although the cRDI and the number of treatment cycles were both higher in group A than in group B (cRDI: 80.6% vs. 73.9%, p = 0.007; 9 vs. 6 cycles, p = 0.004). Primary G-CSF prophylaxis reduced the risk of neutropenia (55.6% to 31.6%, p = 0.003) and febrile neutropenia (18.5% to 1.8%, p = 0.002) and improved OS (8.8 to 14.7 months; hazard ratio [HR]: 1.766, 95% CI: 1.257–2.481, p = 0.001). When administering FOLFIRINOX for MPC, primary G-CSF prophylaxis could be rationalized to reduced AEs and improve survival; more prospective studies are needed.

Doxorubicin uptake in ascitic lymphoma model: resistance or curability is governed by tumor cell density and prolonged drug retention. J Cancer 2020; 11:6497-6506. [PMID: 33046971 PMCID: PMC7545667 DOI: 10.7150/jca.46066] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Accepted: 08/13/2020] [Indexed: 01/14/2023] Open
Abstract
Background/Aims: Chemotherapy resistance of malignancies is a universal phenomenon which unfavorably affects therapeutic results. Genetic adaptations as well as epigenetic factors can play an important role in the development of multidrug resistance. Cytotoxic drug content in plasma of cancer patients is known to variate up to one hundred-fold regardless of the same dose injected per m2 body surface. The relationship between plasma concentrations, tissue uptake, and chemotherapy response is not completely understood. The main objective of this study was to investigate how the identical dose of Doxorubicin (Dox) can result in a different therapeutic response pattern depending on tumor size. Study Design: The study was performed on ascitic EL4 lymphoma in an exponential growth phase focusing on the rapidly changing tumor susceptibility to the Dox treatment. Well distinguishable tumor response patterns (curability, remission-relapse, resistance) were selected to unveil Dox intratumoral uptake and drug tissue persistence. Intratumoral Dox content within peritoneal cavity (PerC) in conjunction with systemic toxicity and plasma pharmacokinetics, were monitored at several time points following Dox injection in tumor bearing mice (TBM) with differing patterns of response. Results: Following intraperitoneal (i.p.) transplantation of 5x104 EL4 lymphoma cells rapid exponential proliferation with ascites volume and animal mass increase resulted in median survival of 14.5 days. The increase in tumor cell mass in PerC between day 3 and day 9 was 112.5-fold (0.2±0.03 mg vs 22.5±0.31 mg respectively). However, tumors at this time interval (day 3 to day 9 post-transplantation) were relatively small and constituted less than 0.05% of animal weight. An identical dose of Dox (15 mg/kg) injected intravenously (i.v.) on Day 3 lead to a cure whereas a TBM injected on day 9 exhibited resistance with a median survival time no different from the untreated TBM control. Injection of Dox resulted in noticeable differences of cellular uptake in PerC between all three groups of TBM ("cure", relapse", "resistance"). Larger tumors were consistently taking up less Dox 60 min after the 15 mg/kg i.v. bolus injection. Higher initial uptake resulted also in longer retention of drug in PerC cells. The area under the concentration curve in PerC cells AUC0-10d was 8.2±0.57 µg/g x h, 4.6±0.27 µg/g x h and 1.6±0.02 µg/g x h in "cure", "relapse" and "resistance" TBM respectively (p<0.05 "relapse" vs "cure" and p<0.001 "resistance" vs "cure"). No differences in plasma Dox pharmacokinetics or systemic hematological effects were observed in TBM following a single i.v. Dox push. Hematologic nadir was tested on day 2 and subsequent hematologic recovery was evaluated on day 10 following Dox administration. Hematologic recovery on day 10 coincided with complete drug efflux from PerC and rising tumor cell numbers in PerC of "relapse" TBM. Myelosuppression and hematological recovery patterns were identical in all surviving animal groups regardless of the tumor size on the day of Dox injection. Conclusions: Within a few days of exponential tumor growth, an identical dose of Dox produced dramatically different responses in the TBM with increasing resistance. Systemic toxicity and plasma pharmacokinetics were indistinguishable between all TBM groups. Initial uptake in tumor cells was found to be consistently lower in larger tumors. Drug uptake in tumor cells was regulated locally - a phenomenon known as inoculum effect in vitro. The duration of drug retention in cells was directly related to initial cellular uptake. The magnitude of Dox cellular retention could potentially play a role in determining tumor remission and relapse.

Abstract
The safety and feasibility of oral fluoroquinolone monotherapy in patients with low-risk febrile neutropenia (FN) were demonstrated in recent studies. Levofloxacin (LVFX) is a commonly prescribed antibiotic; however, evidence for its efficacy against FN is limited. Therefore, in this study, we retrospectively investigated the efficacy of LVFX against low-risk FN in patients with malignant lymphoma at our institution. Treatment success was defined as recovery from fever and neutropenia without alteration of the initial regimen. We recruited 29 patients between January 2013 and December 2018. The median age of the cohort was 64 (range: 21–87) years; 13 (44.8%) were aged over 65 years. In total, 22 patients had diffuse large B-cell lymphoma (DLBCL). Therapy was successful in 24 (82.8%) patients, whereas 5 had treatment failure requiring a change from LVFX to intravenous broad-spectrum antibacterial agents. No deaths related to FN were observed. Two patients required FN-related chemotherapy dose reduction in subsequent cycles. Although this cohort comprised many elderly patients, our study confirmed the efficacy of LVFX in patients with low-risk FN. This may improve the treatment of low-risk FN and malignant lymphoma.

Correlation between hematological parameters and outcome in patients with locally advanced cervical cancer treated by concomitant chemoradiotherapy. Cancer Med 2020; 9:8432-8443. [PMID: 32954675 PMCID: PMC7666723 DOI: 10.1002/cam4.3465] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 08/23/2020] [Accepted: 08/25/2020] [Indexed: 01/28/2023] Open
Abstract
Background Hemoglobin (Hb), white blood cell (WBC), and polymorphonuclear neutrophil (PMN) blood counts may be correlated with outcomes in patients with locally advanced cervical cancer. Methods Hb, WBC, and PMN counts were measured at diagnosis and during concomitant cisplatin‐based chemoradiotherapy (CCRT) in a retrospective sample of 103 patients between 2010 and 2017. Red blood cell (RBC) transfusions were also recorded. The associations between hematological variables and patient overall survival (OS) and recurrence‐free survival (RFS) were assessed by Cox regression models. Results The 3‐year OS and RFS rates were 81.4% and 76.8%, respectively. In addition to tumor size and smoking, OS and RFS were found to be significantly associated with changes in WBC and PMN counts from the first to the last cisplatin cycle. Hb count throughout the treatment and RBC transfusions were not predictive of outcome. Conclusions This study found no association between Hb count or RBC transfusions and outcome. The daily practice of maintaining the Hb count above 12 g/dL during CCRT should be weighed against the potential risks of transfusions. Drops in WBC and PMN counts during treatment positively impacted OS and RFS and could, therefore, serve as biomarkers during CCRT to adapt the follow‐up and consider the need for adjuvant systemic treatments.

Abstract
Cancer chemotherapy induced neutropenia (CCIN) is one of the most common toxicity caused by cytotoxic anticancer agents. Despite granulocyte colony-stimulating factor (GCSF) is widely used in clinical practice, the infection and infection-related mortality rate is still high for lack of functionally mature neutrophils. Saikosaponin d (SSD) is one of the major bioactive constituents of Radix Bupleuri (RB), which exerts immune-modulatory properties. We explored the function of SSD in CCIN therapy, we found that SSD contributed to generate functional mature neutrophils which capable of fighting infection both in vitro and in vivo. Network pharmacology was employed to explore the mechanism, 61 signal pathways might play an important role in CCIN treatment. Western Blot was employed to further confirm the potential pathway involved. We found CBL-ERK1/2 pathway was activated by SSD, followed by upregulating PU.1 and CEBPβ expression and leading to neutrophil differentiation. Our findings suggest a natural regimen SSD which could regenerate microbicidal neutrophils to effectively reduce CCIN-associated infection via activating CBL-ERK1/2, providing a rationale for future therapeutic approaches.

Justification for a Fixed Dose of Eflapegrastim, a Long-Acting G-CSF, in Patients Receiving Docetaxel-Cyclophosphamide Chemotherapy. J Clin Pharmacol 2020; 61:204-210. [PMID: 32827162 DOI: 10.1002/jcph.1723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Accepted: 08/01/2020] [Indexed: 11/09/2022]
Abstract
Eflapegrastim (Rolontis) is a long-acting granulocyte colony-stimulating factor (G-CSF) produced by conjugating a human G-CSF analogue and a human immunoglobulin G4 Fc fragment, linked via a polyethylene glycol linker. Weight-based doses of 45 to 270 μg/kg eflapegrastim (12.3-73.6 μg/kg as G-CSF) were evaluated in a phase 2 study in patients. Based on these results, a fixed dose of 13.2 mg eflapegrastim (3.6 mg G-CSF) was compared with pegfilgrastim (6 mg G-CSF) in 2 phase 3 studies and in a pharmacokinetic single-arm multicenter study. Absolute neutrophil count (ANC) data from these 3 studies were evaluated in patients with early-stage breast cancer who were treated with docetaxel and cyclophosphamide (n = 669). Serum concentrations of eflapegrastim were determined by enzyme-linked immunosorbent assay. Eflapegrastim systemic exposures were higher in cycle 1 than in cycle 3, likely attributable to the higher ANC in cycle 3, increasing neutrophil-mediated clearance. Eflapegrastim elicited a greater effect on ANC than pegfilgrastim in patients at ∼60% of the G-CSF dose. Body weight had no clinically significant effect on response, justifying administration of a fixed dose of eflapegrastim. The results from 2 phase 3 studies demonstrate that eflapegrastim at a fixed dose of 13.2 mg (3.6 mg G-CSF) administered once per chemotherapy cycle is effective in prophylactic treatment of chemotherapy-induced neutropenia.

Abstract
PURPOSE MSB11455 is a proposed biosimilar to the reference pegfilgrastim (Neulasta®). This pivotal equivalence study (NCT03251248) assessed the pharmacokinetic and pharmacodynamic equivalence of MSB11455 to the reference product. METHODS This 2-way, 2-sequence, group-sequential, crossover study was conducted in healthy subjects. Subjects received a single subcutaneous dose of MSB11455 or the reference product (both 6 mg/0.6 mL) on Day 1 of each study period. Pharmacokinetic and pharmacodynamic (absolute neutrophil count; ANC) samples were taken predose and up to day 16 post-dose. Non-compartmental parameters were calculated. Immunogenicity samples were taken pre-dose and up to day 84 after the first dose. Safety was assessed throughout the study. FINDINGS A total of 292 subjects were randomized to therapy and treated; 244 received both treatments. For all primary pharmacokinetic and pharmacodynamic parameters, 90% repeated confidence intervals of geometric means ratio of MSB11455 to the reference product were within the pre-defined equivalence range (80.00%-125.00%) for AUC0-∞ (96.59-112.82); AUC0-last (97.29-113.96), Cmax (97.13-114.99), maximum observed effect on ANC (98.74-102.39), and area under the effect-time curve from time zero to time to last quantifiable concentration (97.30-100.23). Safety, tolerability, and immunogenicity were comparable between treatments. No filgrastim-specific neutralizing antibodies were detected with either treatment sequence. IMPLICATIONS Pharmacokinetic and pharmacodynamic equivalence of MSB11455 and the reference product was shown, with comparable immunogenicity, safety, and tolerability between treatments. The study supports the biosimilarity of MSB11455 to the reference product. ClinicalTrials.gov identifier: NCT03251248.

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.
