The purpose of this study is to quantify the impact of adopting biosimilar granulocyte colony-stimulating factors (G-CSFs) for febrile neutropenia (FN) primary prophylaxis (PP) from a US practice perspective. <\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p> A 1-year economic analysis on real-world direct drug costs and health care resource utilization was conducted in a hypothetical cohort of 500 patients with nonmyeloid cancer receiving chemotherapy. The first model simulated total cost savings of biosimilar versus reference G-CSFs over six cycles of chemotherapy. The second model evaluated cost and outcome implications of expanding the use of biosimilar G-CSFs to an additional 10% of patients at intermediate FN risk. <\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p> Based on real-world evidence over 1 year, a total of 121 of 500 patients received G-CSF prophylaxis resulting in cost savings that ranged from $0.54M US dollars (USD) (short-acting, eg, filgrastim) to $1.68M USD (long-acting, eg, pegfilgrastim) when switching from reference to biosimilar G-CSFs. Expanding the use of biosimilar G-CSFs allowed an additional 24 patients to receive prophylaxis of FN, leading to cost savings of $0.03M USD or $1.19M USD, with a reduction of $0.08M USD in FN-related resource utilization cost. The per-patient per-year cost saving for long-acting G-CSFs was about $3,000 USD. <\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION:<\/jats:title><jats:p> The implementation of biosimilar versus reference G-CSFs to OCM-participating practices results in a reduction of costs and facilitates achieving OCM metrics by improving patients' outcomes while expanding biosimilar G-CSFs access to patients at intermediate risk of chemotherapy-induced FN.
