What patient, physician and practice characteristics are associated with biosimilar usage for the biologicals filgrastim and infliximab was a question asked by researchers from the US [1].

British Columbia adds adalimumab to biosimilar switching programme

Biosimilars/General | Posted 16/04/2021

British Columbia (BC), the first province in Canada to switch patients to biosimilar drugs, has added adalimumab to its switching programme. Almost 6,000 patients will be transitioned from originator adalimumab (Humira) to one of five biosimilar versions.

Biosimilars in the treatment of psoriasis

Biosimilars/Research | Posted 16/04/2021

A recent paper by Spanish dermatologists reviews the principles of biosimilarity and equivalence trials that have led to the approval of the available adalimumab biosimilars [1]. Given the current sophistication of the analytical processes, the need to include therapeutic equivalence trials for some drug classes might be eventually waived, but they are currently standard. Equivalence trials are designed to establish that the efficacy and safety of the biosimilar are similar to those of the reference biological, with a predetermined margin of equivalence that in psoriasis ranges from ±14% to ±18%. Lower margins would imply potentially unaffordable sizes of treatment groups. The primary endpoint of the study and the timing of the determination may or may not be the same as those used in the pivotal trials of the reference biological, but the number of patients included is intentionally lower; the statistical design of equivalence trials is currently the subject of active research. In many equivalence studies, biosimilars obtain response rates higher than those reported in the pivotal studies for the originator, probably because of the absence of a placebo arm, which would tend to raise researchers’ and patients’ efficacy expectations.

Advances for Formycon and Alteogen’s eye disease biosimilar candidates

Biosimilars/News | Posted 16/04/2021

In March 2021, Formycon confirmed the resubmission strategy for their Lucentis® (ranibizumab) biosimilar candidate (FYB2010) in the US. In addition, Alteogen announced the completion of its phase I clinical trial of Eylea® (aflibercept) biosimilar (ALT-L9). Both of these biological drugs are used to treat conditions leading to the loss of vision.

Adalimumab biosimilar FKB327 causes less pain than originator

Biosimilars/Research | Posted 09/04/2021

Fujifilm Kyowa Kirin Biologics’ adalimumab biosimilar FKB327 has been found to cause less injection-site pain compared to the reference product, according to data from more than 1,001 subjects and patients [1].

Biosimilars regulation, clinical trials, approval and adverse events in Malaysia

Biosimilars/Research | Posted 09/04/2021

Compared to chemical drugs, biologicals are more expensive because of their complicated manufacturing processes. Patients often use biologicals for long-term therapy, which may exert huge budgetary pressure on healthcare systems. One alternative solution to address this issue is to use biosimilars that are similar to the originator biologicals, with no clinical differences in terms of quality, efficacy, safety and immunogenicity. In Malaysia, the National Pharmaceutical Regulatory Agency (NPRA) approved the country’s first biosimilar, somatropin, in 2010. Since then, the number of approved biosimilars and clinical trials on biosimilars continue to rise. With increased use of biosimilars, an increased number of adverse events (AEs) is expected because like any other biological, they may elicit immunogenic reactions.
