Canada’s Ontario introduces biosimilars switching policy
The Canadian province of Ontario is the latest to introduce a biosimilars switching policy. Under the terms of the policy, Ontario Drug Benefit (ODB) recipients who are on an originator biological will be required to transition to a Health Canada approved biosimilar version of the drug.
Biosimilar advances for Alvotech-Teva and setback for Biocon Biologics

Drug survival of adalimumab biosimilars in psoriasis treatment in Spain
A review by López-Ferrer A et al. entitled ‘Drug survival of adalimumab biosimilars in real-world treatment of psoriasis: A Spanish multicenter study’ provided perspective of the factors associated with biosimilar adalimumab survival in Spain [1].
Advances for Bio-Thera’s secukinumab and mepolizumab copy biologicals
China’s Bio-Thera Solutions announced in November 2022 that dosing has begun in a phase III clinical study for BAT2306, a proposed copy biological of arthritis anti-inflammatory treatment, Cosentyx (secukinumab). In addition, the company also recently announced a phase I clinical study to compare the pharmacokinetics and safety of BAT2606, a proposed copy biological of asthma treatment, Nucala (mepolizumab), to US-sourced and EU-sourced reference product in normal healthy volunteers.
Pegfilgrastim biosimilars in US supportive oncology
Humphreys et al. published a narrative review article concerning the administration options and the economic considerations of biosimilar pegfilgrastim in supportive cancer treatment in the US to maximize patient benefit[1].
Investigating cell, tissue and gene therapy products and their regulation
Cell, tissue and gene therapy products or (CTGTPs) are often breakthrough therapies with immense potential in treating diseases with no cure or rare diseases with high treatment burdens. However, few of such therapies have been approved and some have been recalled due to safety issues. Now, a study published in GaBI Journal [1] has investigated these therapies and the manufacturing and regulatory challenges they pose.
FDA and EMA file acceptance of Biogen’s tocilizumab biosimilar
Biogen announced on 9 December 2022 that the US Food and Drug Administration (FDA) has accepted for review the abbreviated Biologics License Application (BLA) for BIIB800, a biosimilar candidate referencing Roche’s Actemra/RoActemra (tocilizumab); and on 30 September 2022 that the European Medicines Agency (EMA) has accepted the Marketing Authorization Application for BIIB800.
AVT02 biosimilarity with Humira proved in chronic plaque psoriasis treatment

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].
