Cost-effectiveness of granulocyte colony-stimulating factors (G-CSFs) for the prevention of febrile neutropenia (FN) in patients with cancer.

PURPOSE: Clinical practice guidelines recommend the use of all approved granulocyte colony-stimulating factors (G-CSFs), including filgrastim and pegfilgrastim, as primary febrile neutropenia (FN) prophylaxis in patients receiving high- or intermediate-risk regimens (in those with additional patient risk factors). Previous studies have examined G-CSF cost-effectiveness by cancer type in patients with a high baseline risk of FN. This study evaluated patients with breast cancer (BC), non-small cell lung cancer (NSCLC), or non-Hodgkin's lymphoma (NHL) receiving therapy who were at intermediate risk for FN and compared primary prophylaxis (PP) and secondary prophylaxis (SP) using biosimilar filgrastim or biosimilar pegfilgrastim in Austria, France, and Germany. METHODS: A Markov cycle tree-based model was constructed to evaluate PP versus SP in patients with BC, NSCLC, or NHL receiving therapy over a lifetime horizon. Cost-effectiveness was evaluated over a range of willingness-to-pay (WTP) thresholds for incremental cost per quality-adjusted life year (QALY) gained. Sensitivity analyses evaluated uncertainty. RESULTS: Results demonstrated that using biosimilar filgrastim as PP compared to SP resulted in incremental cost-effectiveness ratios (ICERs) well below the most commonly accepted WTP threshold of €30,000. Across all three countries, PP in NSCLC had the lowest cost per QALY, and in France, PP was both cheaper and more effective than SP. Similar results were found using biosimilar pegfilgrastim, with ICERs generally higher than those for filgrastim. CONCLUSIONS: Biosimilar filgrastim and pegfilgrastim as primary prophylaxis are cost-effective approaches to avoid FN events in patients with BC, NSCLC, or NHL at intermediate risk for FN in Austria, France, and Germany.

Impact of health system specialty pharmacies on total cost of care in cancer treatment, a multisite review.

INTRODUCTION: Integrated delivery networks can use medically integrated dispensing of oral oncolytics on site through health system specialty pharmacies. There is little published research examining cost savings. Our objective was to demonstrate the financial value of health system specialty pharmacies among patients receiving oral oncolytics dispensed through fully, partially, and non-integrated dispensing strategies. METHODS: This was a retrospective cohort study of adult patients from Symphony Health's Integrated Dataverse® repository who filled a prescription for an agent of interest from 7/1/16-6/30/20 that was written within 25 US health systems. Outcomes included costs, healthcare resource utilization, and duration of therapy. RESULTS: In total, 36,816 patients were included; 986 patients (2.7%) integrated, 1,822 (4.9%) partially integrated, and 34,008 (92.4%) non-integrated. Mean 6-month medical charge and oncolytic prescription costs were lower for the integrated group ($36,831; $55,786) than the partially integrated ($46,304, p = 0.053; $63,295, p = 0.071) and non-integrated groups ($54,261, p < 0.001; $65,005, p = 0.004). In most healthcare resource utilization categories, the integrated group had the lowest patient percentage utilizing medical care. Duration of therapy was lower on average by ∼3 months in the integrated vs non-integrated group, which may represent closer monitoring of patient medical records and need for fills vs autoship practices. CONCLUSIONS: Patients receiving oral oncolytics through medically integrated dispensing at health system specialty pharmacies may have lower medical and pharmacy costs and decreased healthcare resource utilization. This study adds to the growing body of literature supporting integrated delivery networks and integrated dispensing. Further research is needed to demonstrate the value of medically integrated dispensing through health system specialty pharmacies in the delivery of treatment to patients with cancer and other high-cost diseases.

Economic Impact of Transformation to Acute Myeloid Leukemia Among Actively Managed Patients with Higher-Risk Myelodysplastic Syndromes in the United States.

INTRODUCTION: Transformation of higher-risk myelodysplastic syndromes (MDS) to acute myeloid leukemia (AML) may be associated with increased healthcare resource utilization (HCRU) and costs. To describe this economic impact, HCRU and costs were compared between US patients who experienced transformation to AML and those who did not. METHODS: Using the Optum administrative claims data, this retrospective matched cohort study identified patients (≥ 18 years old) with higher-risk MDS who initiated first-line therapy between January 1, 2008, and June 30, 2019. Patients whose disease transformed to AML were matched 1:1 to patients whose disease did not transform, based on the duration of follow-up. The follow-up period was divided into two periods: pre- (before transformation to AML) and post-AML (after transformation to AML). For patients who did not transform to AML, pre- and post-AML periods were determined using the transformation date of their matched pair. HCRU and total adjusted costs (2019 US dollars, $) were compared between patients who transformed to AML and those who did not. RESULTS: A total of 118 matched patient pairs were included in the study. The hospitalization rate was significantly higher in patients who transformed than in those who did not during the entire follow-up (58.8% vs. 44.1%; P = 0.0295) and post-AML (47.5% vs. 28.0%; P = 0.0028) periods. Across all periods, supportive care use was significantly higher among patients who transformed to AML vs. patients who did not transform. Adjusted mean monthly costs for patients with higher-risk MDS who transformed to AML were higher than those who did not transform ($25,964 vs. $19,150; P < 0.0001). The observed total cost difference was more notable in the post-AML period ($36,424 vs. $14,860; P < 0.0001). CONCLUSIONS: Patients with higher-risk MDS whose disease transformed to AML incurred significantly higher healthcare costs compared to those whose disease did not transform, highlighting the important need for treatments that prevent or delay transformation.
