Biosimilars in the age of patient-centricity

Biosimilars/Research | Posted 06/03/2020

In 2020, nearly all pharmaceutical companies claim to be ‘patient-centric’. In fact, some companies have even initiated processes of designing new treatments ‘around the patient’ and convened ‘Patient Advisory Boards’ to ensure patients provide their input into clinical trial design. In addition, though to a lesser extent, some have also developed educational programmes to ensure clinicians and patients truly understand the use and function of biosimilars. Regulators have also participated in the effort to ensure that patients consent to be prescribed biosimilar treatments and are well informed of their relative risks and benefits. President of the French Association of Pharmaceutical Medicine, Dr Francois-Xavier Frapaise, discusses how these latest ‘patient-centric’ efforts affect patients [1].

Is switching to biosimilar infliximab safe?

Biosimilars/Research | Posted 14/06/2019

Building on a number of studies on biosimilar infliximab for inflammatory bowel disease (IBD), a recent review shows switching to CT-P13 is safe, but more evidence is needed on switching back to originator and switching between biosimilars [1].

Safety of switching between reference products and biosimilars

Biosimilars/Research | Posted 29/05/2020

The safety of switching a patient under chronic treatment with a reference biological to a biosimilar has been a topic of ongoing debate since the first biosimilar approval in Europe in 2006. The topic sparked further discussion with the arrival of the more complex monoclonal antibody biosimilars. Concerns have been raised that switching between highly similar but non-identical versions of a biological medicine might lead to increased immunogenicity and as such, impact treatment outcomes. The existing stakeholder uncertainty regarding the safety of switching may have been curbing the use of biosimilars in clinical practice and guidance to support healthcare professionals with clinical decision-making is needed.

Do patent strategies delay market entry of biosimilar monoclonal antibodies in Europe?

Biosimilars/Research | Posted 22/05/2020

Patents have been shown to be the main determinant to guarantee market exclusivity of originator biologicals [1], with patent disputes causing uncertainty on a patent’s validity and subsequently potentially influencing launch dates of competitor products, such as biosimilars [2]. In addition, the launch date of a biosimilar might be affected by strategies for prolongation of exclusivity rights on the originator product, such as filing additional patents for a new formulation, new indication or new dosage regime [3].

Scientific evidence in development of trastuzumab biosimilar ABP 980

Biosimilars/Research | Posted 15/05/2020

ABP 980 (Kanjinti) is a biosimilar to trastuzumab reference product (RP) (Herceptin), a monoclonal antibody directed against human epidermal growth factor receptor 2 (HER2). A biosimilar is highly similar to a licensed biological with no clinically meaningful differences in safety, purity and potency [1, 2]. Kanjinti is approved in the US, European Union, and as trastuzumab BS [trastuzumab biosimilar 2] in Japan for all Herceptin indications, which include treatment of HER2 positive (HER2+) metastatic breast cancer, early breast cancer (EBC), and metastatic gastric cancer [3-5]. Development and approval were based on a totality of evidence (TOE) approach, involving stepwise generation of comparative analytical (structural and functional), preclinical, and clinical (pharmacokinetics [PK], pharmacodynamics [PD], efficacy, safety and immunogenicity) evidence [6].

Now, the province of Alberta is also considering plans to stop coverage of originator biologicals and switch patients to biosimilars for certain indications. The new policy, if introduced, will apply to the approximately 30,000 patients in Alberta living with inflammatory bowel disease (IBD) [2].

Tackling the challenge of safe automatic substitution of biologicals

Biosimilars/Research | Posted 13/03/2020

The costs of biologicals are challenging the sustainability of pharmacotherapy. Affordable biosimilars are expected to trigger competition within the biologicals market. Increasing real-world experience on biosimilars and clinical switching studies have led to position papers supporting the interchangeability of biosimilars with their reference products under the supervision of the prescriber [1]. However, the uptake of biosimilars has been poor in Finland, since physicians have been reluctant to prescribe biosimilars, especially in the outpatient setting. One option to stimulate the uptake of biosimilars is the automatic substitution of biologicals at the pharmacy level.

Efficacy, safety and immunogenicity of adalimumab biosimilar BI 695501

Biosimilars/Research | Posted 22/06/2018

Adalimumab is the most commonly prescribed biological and is approved for rheumatoid arthritis as well as psoriasis, psoriatic arthritis, along with Crohn’s and ulcerative colitis. Its patent life terminated in 2016 in the US [1]. However, in the US AbbVie has stated that, although the composition of matter patent covering Humira expired in December 2016, non-composition of matter patents covering Humira expire no earlier than 2022. The company has therefore made settlement agreements with Amgen and Samsung Bioepis, delaying the launch of biosimilars until January 2023 [2, 3].

Reasons and solutions for the high cost of insulin in the US

Biosimilars/Research | Posted 21/02/2020

The most commonly used forms of analogue insulin cost 10 times more in the US than in any other developed country. In fact, the cost of insulin in the country has more than tripled in the past 10 years [1]. This has led to patients rationing their insulin; something that does not happen in other developed countries, but is common in the US.

This is a subject fraught with issues related to both the law and the ethics of switching. Authors Blake Murdoch and Timothy Caulfield of the Health Law Institute, Faculty of Law, University of Alberta, Edmonton, Alberta, Canada, try to address how such issues might affect Canada [1].
