Biosimilars/Research
AVT02 biosimilarity with Humira proved in chronic plaque psoriasis treatment
Results of clinical patient trials of Alvotech’s high concentration formulation biosimilar of adalimumab, AVT02, demonstrate comparable efficacy, safety and immunogenicity to the reference product Humira, according to a study published in Biodrugs [1].
Investigating biosimilar product drift and divergence
Following the establishment of biosimilarity, there are no regulations that require manufacturers to perform quality or clinical studies to compare biosimilar versus originator products post-approval. In an investigation published in GaBI Journal [1], Dr Pablo Matar examined the concept of biosimilar manufacturing ‘drift’ and product divergence [2].
Biosimilars, are they comparable to their reference counterparts?
Biologicals such as rituximab and trastuzumab have improved treatment outcomes for many cancers. However, due to their high economic burden, ‘highly similar’ products known as biosimilars have been developed and used. Yet, there is still concern surrounding comparability of efficacy and safety between the biosimilar and its reference biological, especially regarding patients switching from the reference to the biosimilar.
The cost savings of non-medical switching in dermatology
Non-medical switching is when a patients' therapy is changed due to reasons not linked to their health and can involve non-interchangeable drugs, potentially affecting the treatment outcomes.
Switching from adalimumab originator and ABP501 to SB5 in arthritis patients
The introduction and availability of biosimilars entails a considerable increase in the patient access as well as a decrease in the patient cost. Thus, biosimilars could be the answer to the economic impact of the reference biological.
Updates for European Pharmacopoeia monographs for biotherapeutic products
The European Pharmacopoeia produces monographs for biotherapeutic products that are publicly available and considered the standard for defining the quality of these medicines. A recent study published in GaBI Journal [1] examines whether the challenges posed by complex products such as the introduction of biosimilars, have been met by new elements that have been added to the monographs.
Recommendations for improving biosimilar regulations in Latin America
The biosimilar regulatory scenario is very diverse and varies widely in the large group of Latin American countries. Authors Teran et al. presented some recommendations for making biosimilar regulations in Latin America more homogeneous and comprehensive [1].
Successful trials for Sandoz and Lannett biosimilars
On 19 September 2022, Sandoz announced positive results following its ROSALIA I/III clinical trial study for its proposed biosimilar denosumab. This follows the August announcement that Lannett Company successfully completed subject dosing in the clinical trial of its biosimilar insulin glargine.
Recommendations to address challenges to biosimilars in Latin America
After reviewing the regulatory landscape for biosimilars [1] and access to biosimilars for cancer treatments in Latin America [2], authors Teran et al. advised several recommendations to address challenges related to poor access to biosimilars in Latin America healthcare systems.
Totality of evidence for biosimilar pegfilgrastim Ziextenzo
Agarwala et al. have recently published a review on the totality of evidence (ToE) for the biosimilar pegfilgrastim Ziextenzo® (LA-EP2006) matching the European Union- (EU) and US-reference biological pegfilgrastim Neulasta® (marketed by Amgen) [1].
