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.

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.

Biosimilars of ustekinumab

Biosimilars/General | Posted 09/04/2021

Ustekinumab is a humanized monoclonal antibody that interferes with the triggering of the body’s inflammatory response through the suppression of certain cytokines. Specifically, it blocks interleukin IL 12 and IL 23 which help activate certain T cells. It binds to the p 40 subunit of both IL 12 and IL 23 so that they subsequently cannot bind to their receptors. It is indicated for the treatment of Crohn’s disease, psoriasis and psoriatic arthritis.

Public health impact of using biosimilars and relevance of automated follow-up

Biosimilars/Research | Posted 26/03/2021

Biological reference drugs and biosimilars have highly complex structures. Biosimilars need to demonstrate their biosimilarity during their development but unpredictable variations can remain, such as micro-heterogeneity. The healthcare community may raise questions regarding the clinical outcomes induced by this micro-heterogeneity. Indeed, unwanted immune reactions may be induced for numerous reasons, including product variations. However, it is challenging to assess these unwanted immune reactions because of the multiplicity of causes and potential delays before any reaction. Moreover, safety assessments, as part of preclinical studies and clinical trials, may be of limited value with respect to immunogenicity assessments because they are performed on a standardized population during a limited period. Real-life data could therefore supplement the assessments of clinical trials by including data on the real-life use of biosimilars, such as switches. Furthermore, real-life data also include any economic incentives to prescribe or use biosimilars.
