Cross-sectional patient survey of biological medicine users in Finland to investigate the types of guidance needed by patients in order to carry out their treatment successfully.
BMJ Open
January 2025
Oriola Finland Oy, Espoo, Uusimaa, Finland
Background: The use of new biological medicines as standard treatment is expected to increase substantially and cover new therapeutic indications in the near future. Interchange of biological medicines in pharmacies increases the need for patient guidance.
Objectives: The study aims to gain a patient perspective on biological medicine users' needs and wishes regarding patient guidance by exploring what kind of information patients wish to receive and to further investigate the potential differences in needs between originator biological medicine users and biosimilar users.
Aggregation of human plasma and of human blood induced in vitro by pegfilgrastim originator formulation buffer and pegfilgrastim products.

PEGylated recombinant human granulocyte colony stimulating factor (pegfilgrastim) is used clinically to reduce the incidence and duration of severe neutropenia in patients who have received chemotherapy treatment. Pegfilgrastim products are administered by subcutaneous injection. We herein report that solutions of pegfilgrastim originator product Neulasta®, of a biosimilar product candidate, and also of the pegfilgrastim originator formulation buffer, induced aggregate formation when mixed in vitro with human plasma, and formation of large membranous aggregated structures when mixed with human blood.

Background: Pegfilgrastim is a long-acting recombinant human granulocyte colony-stimulating factor biologic that is indicated to reduce the incidence of infections, manifested by febrile neutropenia, in patients receiving myelosuppressive anti-cancer drugs and to increase survival in patients acutely exposed to myelosuppressive doses of radiation. Due to the high cost of biologic therapy and the scarcity of biosimilar alternatives, there is an unmet medical need for targeted biologics.
Objective: This comparative analytical investigation aimed to confirm the similarity of biosimilar Stimufend® (pegfilgrastim-fpgk) to reference product Neulasta® (pegfilgrastim).
Mecapegfilgrastim for prophylaxis of febrile neutropenia in children and adolescents with rhabdomyosarcoma or Ewing sarcoma: a prospective, single-arm, pilot study.

Background: The chemotherapy regimens recommended for both rhabdomyosarcoma (RMS) and Ewing sarcoma (ES) patients are myelosuppressive and can reduce the absolute neutrophil count (ANC) and subsequently increase the risk of febrile neutropenia (FN). However, only a few studies have focused on the efficacy and safety of granulocyte-colony stimulating factor (G-CSF) drugs in pediatric and adolescent patients with RMS and ES. Our objective was to investigate the efficacy and safety of mecapegfilgrastim, a biosimilar of pegfilgrastim, in prophylaxis of FN for pediatric and adolescent patients with RMS or ES.

Biosimilars offer the potential for cost savings and expanded access to biologic products; however, there are concerns regarding the rate of biosimilar uptake. We assessed the relationship between biosimilar and originator pricing, coverage, and market share by describing four case studies that fall into two categories: (1) sole preferred coverage strategy (ie, aim is to have originator product preferred; biosimilar(s) non-preferred), defined as steep average sales price (ASP) reductions for originator products (decline in net prices by at least 50% following the introduction of biosimilar competition by 2022) and (2) non-sole preferred coverage strategy (ie, aim is to have originator product preferred alongside biosimilar products), defined as moderate ASP reductions for originator products with (net prices did not decline by at least 50% of its pre-biosimilar competition value). We found that originators with sole preferred coverage strategies maintained formulary preference and market share relative to originators with non-sole preferred coverage strategies.
