On-body injector pegfilgrastim for chemotherapy-induced neutropenia prophylaxis: Current Status

Abstract

Introduction: Myelosuppression, a challenge in cancer treatment, often results in severe complications. Prophylactic granulocyte colony-stimulating factors, particularly pegfilgrastim, mitigate chemotherapy-induced neutropenia. This narrative review evaluates the role of on-body injector (OBI) devices for pegfilgrastim administration. A comprehensive search strategy of PubMed and AI-powered intuitive search tools, complemented by authors’ contributions, yielded a body of papers presenting evidence on OBI devices, their effectiveness and safety, the benefits and challenges of OBI versus pre-filled syringe administration, patient preferences for pegfilgrastim administration, and economic considerations. Discussion: OBI devices prove effective and safe, with advantages such as reduced clinic visits and enhanced adherence. Studies highlight cost-efficiency and expanded access, emphasizing the socioeconomic context. Patient and provider preferences underscore the potential of OBI devices in cancer care, with implications for healthcare resource utilization and pharmacoeconomics. Conclusion: The value proposition of OBI devices lies in improving patient outcomes, convenience, resource optimization, and enhancing the overall cancer care experience. As biosimilar OBIs enter the market, they may offer cost savings, further influencing their adoption and their positioning as a cost-efficient alternative in cancer care. Ongoing research and technological advancements are expected to contribute to the broader acceptance of OBI devices in cancer care delivery.
