Biosimilars/General

Biosimilars approved in Australia

Last update: 26 February 2021

In Australia, the legal framework for approving medicines was established via the Therapeutic Goods Act 1989.

Biosimilar approvals and patent litigation in the US

Authors from Law360 have examined biosimilar approvals by the US Food and Drug Administration (FDA) under the Biologics Price Competition and Innovation Act of 2009 (BPCI Act) and ensuing patent litigation actions. They also discuss why the lack of new approvals and litigation in 2020 does not suggest reduced interest in biosimilars but signals a new wave of biosimilars on the horizon [1].

Biosimilars of bevacizumab

Last update: 5 February 2021

Bevacizumab is a humanized monoclonal antibody. It inhibits angiogenesis (the formation of new blood vessels) by blocking the action of vascular endothelial growth factor A (VEGF-A). Bevacizumab can therefore slow the growth of new blood vessels in tumours and is used to treat various cancers, including colorectal, lung, breast, glioblastoma, kidney and ovarian.

Samsung biosimilars: denosumab clinical trials begin, while rituximab development is halted

Korea-based Samsung Bioepis (Samsung and Biogen’s joint venture) has initiated phase III trials for its denosumab biosimilar, while development on a rituximab biosimilar through subsidiary company Archigen Biotech has been stopped.

Biosimilars of filgrastim

Last update: 22 January 2021

Filgrastim is a granulocyte colony-stimulating factor (G-CSF). Filgrastim treatment can be used to stimulate the bone marrow to produce more neutrophils (white blood cells) to fight infection in patients undergoing chemotherapy for cancer treatment.

Biosimilars applications under review by EMA – January 2021

The European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the European Union (EU). A legal framework for approving biosimilars was established in 2003. Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or reference drug.

Biosimilars of pegfilgrastim

Last update: 15 January 2021

Pegfilgrastim is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (G-CSF) analogue filgrastim. It serves to stimulate the level of white blood cells (neutrophils). Pegfilgrastim treatment can be used to stimulate bone marrow to produce more neutrophils (white blood cells) to fight infection in patients undergoing chemotherapy.

Biosimilars of trastuzumab

Last update: 15 January 2021

Trastuzumab is a monoclonal antibody that binds to and inactivates the human epidermal growth factor receptor 2 (HER2)/neu receptor. In some cancers, notably certain types of breast cancers, HER2 is over-expressed, and causes cancer cells to reproduce uncontrollably. Trastuzumab is therefore used to treat HER2 positive (HER2+) breast cancers.

Biosimilars in Australia – a-flagging and sustainability

Australia first introduced guidelines for biosimilars back in August 2008 when it adopted a number of guidelines from the EU on similar biological medicinal products [1].

Biosimilars of rituximab

Last update: 8 January 2021

Rituximab is a chimeric monoclonal antibody against the protein CD20, which is primarily found on the surface of immune system B cells. Rituximab destroys B cells and is therefore used to treat diseases that are characterized by excessive number of B cells, overactive B cells or dysfunctional B cells. This includes many lymphomas, leukaemias, transplant rejection and autoimmune disorders.
