Biosimilars/Research | Posted 18/03/2022

The last decade and a half have witnessed a paradigm shift in the way vascular disorders affecting the retina are treated. Anti-vascular endothelial growth factor (VEGF) antibodies have become the mainstay of treatment. These monoclonal antibodies are injected in the vitreous cavity. For the treatment to be effective, repeated injections every 4 to 8 weeks over many years need to be given, which proves to be quite expensive.

Will the unclear path of biosimilar interchangeability become clearer?

Biosimilars/Research | Posted 11/03/2022

Biosimilar use has led to increased access to biological treatments for some molecules wherein switching from originator to biosimilar has been one means to exchange products [1, 2]. Another but less applied way to exchange the products is via substitution by a pharmacist, i.e. without informing the prescriber [2]. Substitution of biosimilars is a topic with many contrasting views and has been highly debated [3-12]. More clarity on the matter is needed because health care has reached a point where policy decisions need to be made about whether substitution should become a practice in biosimilar use. Therefore, researchers from Denmark, Sweden and The Netherlands investigated the views of experts from medicines agencies and the pharmaceutical industry on the science underpinning interchangeability of biosimilars [13].

Biological standardization of bevacizumab: impact on global harmonization of potency assessment

Biosimilars/Research | Posted 21/01/2022

Bevacizumab is a humanized monoclonal antibody (mAb) targeting vascular endothelial growth factor (VEGF), which causes excessive growth of new blood vessels from pre-existing ones in the form of angiogenesis, underlying pathology of cancers and intraocular neovascular diseases. Through binding to soluble VEGF, bevacizumab sterically blocks the interaction of VEGF with VEGF receptor 2 on endothelial cells and thereby interrupts the activation of downstream signalling for angiogenesis. Bevacizumab is indicated for the treatment of a range of cancers, including metastatic colorectal cancer, metastatic breast cancer and non-small-cell lung cancer. It is also used for off-label treatment of eye diseases including neovascular age-related macular degeneration and diabetic macular oedema.

Patent litigation insights on barriers to US biosimilar market growth

Biosimilars/Research | Posted 29/10/2021

High prices of biological drugs have placed substantial strain on the US healthcare system. To help address this problem, Congress passed the Biologics Price Competition and Innovation Act of 2009 (BPCI Act) as part of the Affordable Care Act, which created an abbreviated approval pathway for biosimilars – versions of ‘originator’ biological drugs made by different manufacturers. To resolve disputes over whether a biosimilar manufacturer would infringe patents on the originator biological by entering the market, the BPCI Act included a multi-step litigation process, which starts when the biosimilar manufacturer submits its abbreviated biological license application to the US Food and Drug Administration (FDA). However, a decade after its passage, the BPCI Act has spurred only limited competition [1].

Demand for similar biotherapeutic products in Latin America

Biosimilars/Research | Posted 02/07/2021

Development of biologicals has experienced steady growth over the past three decades. Expiration of patents on many originator biologicals, such as insulin, human growth hormone and erythropoietin, has opened the door for the development of biosimilars. The high cost of biologicals, however, has limited their accessibility, particularly in developing countries. Biosimilars offer much-needed affordability and hence improved accessibility. Global health agencies, such as the World Health Organization, are engaged in developing a prequalification program in order to help countries that do not have strong regulatory systems [1].

Competition from biosimilars drives price reductions for biologicals in France

Biosimilars/Research | Posted 15/10/2021

The US has experienced a policy debate as to whether competition from biosimilars is the best strategy for achieving price reductions for biologicals or, rather, whether direct price regulation after loss of patent exclusivity would be more effective.

Candidate trastuzumab biosimilar AryoTrust

Biosimilars/Research | Posted 08/10/2021

Biologicals are one of the interesting and effective treatment options which can save the lives of many patients, however, their high cost and restricted access for some patients remains a challenge. The emergence of biosimilars, with their similar efficacy and safety profiles, could be a solution for this hurdle. According to the European Medicines Agency (EMA) guidance entitled ‘Biosimilars in the EU – information guide for healthcare professionals’, a biosimilar is ‘a biological medicine highly similar to another biological medicine already approved in the EU’ [1]. Biosimilars are required to have the same standards of pharmaceutical quality, safety and efficacy as for originator biologicals in order to obtain marketing authorization. Although, according to the EMA guidance ‘approval of biosimilars builds on existing scientific knowledge on safety and efficacy of the reference medicine gained during its clinical use, so fewer clinical data are needed’ [2].
