Biosimilars/Research
Perceptions of biosimilars among US cancer patients
Amid increasingly expensive cancer treatments, researchers in the US explored perceptions of generic drugs among a group of 75 patients, in findings presented alongside the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting.
Comparison of darbepoetin alfa and epoetin alfa for the treatment of renal anaemia
Darbepoetin alfa (DA-α) manufactured by Hetero Biopharma (Hetero) is the first long-acting erythropoiesis-stimulating agent with extended dosing intervals. This gives it an advantage over epoetin alfa (EPO) and epoetin beta. It also has a half-life three-fold longer than that of EPO.
Safety of SC form of infliximab biosimilar CT-P13
Positive results for Celltrion Healthcare’s (Celltrion) subcutaneous (SC) formulation of its infliximab biosimilar, CT-P13 (Remsima), have been presented at the European Congress of Rheumatology 2019 (EULAR 2019) [1].
Positive phase III results for bevacizumab copy biological IBI305
Innovent Biologics (Innovent) has presented positive phase III results for its bevacizumab copy biological IBI305 at the 55th Annual Meeting of the American Society of Clinical Oncology (ASCO).
Extensive characterization of biosimilars: a pegylated filgrastim study
Pegfilgrastim, is a 38 kDa, pegylated form of filgrastim, with a 20 kDa monomethoxypolyethylene glycol (mPEG) molecule covalently bound to the N-terminal methionyl residue of filgrastim developed by Amgen. Attachment of the mPEG-moiety enables a longer half-life, that enables only once-per-cycle administration for the management of chemotherapy-induced neutropenia. This results in a much simpler treatment regime for patients. The biosimilar version of pegfilgrastim developed by Intas Pharmaceuticals, and marketed by Accord Healthcare under the brand name Pelgraz, is one of the first pegfilgrastim biosimilars to be approved for market authorization in the European Union (EU) [1].
Distinct suffixes will aid biosimilar competition, says new research
The differential naming of originator and biosimilar products supports accurate pharmacovigilance and promotes biosimilar uptake, finds a literature review recently published in GaBI Journal [1].
Real-world data on switching of etanercept biosimilars
Real-world and clinical data from different studies involving switching to etanerept biosimilars were presented at the European Congress of Rheumatology 2019 (EULAR 2019) [1].
Long-term safety results for adalimumab biosimilar
ABP 501 is an adalimumab biosimilar which was compared to reference adalimumab in a 24-week phase lll study demonstrating equivalent efficacy and similar safety and immunogenicity [1]. The results of this clinical trial, along with the totality of evidence from analytical and biofunctional evaluation, lead to the approval of this adalimumab biosimilar for rheumatoid arthritis in the European Union and the US. ABP 501 is marketed as Amgevita in Europe and other markets. However, it will not be available in the US until 2023 due to an agreement between Amgen, the developer of the biosimilar, and AbbVie who manufactures the originator product, Humira (adalimumab) [2].
Positive phase III data for adalimumab copy biologicals
Positive phase III data for adalimumab copy biologicals has been presented at the European Congress of Rheumatology 2019 (EULAR 2019) [1].
Positive results for rituximab non-originator and copy biologicals
Positive results for the rituximab non-originator biological BCD-020 (AcellBia) and for the rituximab copy biological HLX01 (Hanlikon) have been presented at the European Congress of Rheumatology 2019 (EULAR 2019) [1, 2].
