Infliximab biosimilars for IBD patients: experience from Italy

Biosimilars/Research | Posted 12/03/2021

In the last 20 years, biological drugs have become the mainstream therapy for patients affected by moderately-to-severely active inflammatory bowel disease (IBD), even though they are associated with a significant increase in health-related costs. After the expiry of patents on originator drugs, the advent of antitumour necrosis factor alfa (TNF-α) biosimilars resulted in considerable cost-savings and increased patients’ access to these drugs. After having completed registration trials in rheumatic diseases [1, 2], the infliximab biosimilar CT P13 obtained approval based on a comprehensive comparability exercise, for all other indications, including IBD. Accordingly, physicians started to increasingly prescribe biosimilars for patients with IBD – including those that were both anti-TNF-α naïve and experienced. There is growing evidence that early introduction of biological therapy in IBD is associated with more favourable outcomes in the medium to long term. Keeping that in mind, it follows that the advent of biosimilars has the potential to allow more patients to have access to biological therapy at an earlier stage of disease, which could contribute to prevent disease progression and damage accumulation, with a consequential improvement in patients’ quality of life.

Efficacy and safety of interferon beta-1a (ReciGen) in COVID-19

Since COVID-19, caused by SARS-CoV-2, emerged as a worldwide concern and was declared a pandemic, finding a safe and effective treatment for this disease has been a top priority. Different treatment candidates, including interferon [1], remdesevir [2], tocilizumab [3], and dexamethasone [4] have been investigated in multiple clinical trials.

Improving biosimilar use in clinical practice

Uncertainty about biosimilars and lack of motivation among healthcare providers and patients to use them may have been curbing biosimilar use. Guidance on how to implement biosimilars in clinical practice and how to incentivize stakeholders to use biosimilars may help to realize the benefits offered by biosimilars for healthcare systems and patients.

Improving stakeholder understanding about biosimilars

The arrival of biosimilars provides benefits for healthcare systems and patients by lowering treatment costs and improving patient access to biologicals. Despite these benefits and demonstrated comparability with the reference biological, the use of biosimilars varies across regions and remains limited in some cases. This may be partially due to a lack of knowledge and understanding among healthcare professionals and patients about biosimilars, limiting their willingness to use them.

Interchangeability, naming and pharmacovigilance of biosimilars

Results of a survey was carried out by the World Health Organization (WHO) revealed that challenges still remain when it comes to the regulatory evaluation of biosimilars [1].

Improving the understanding of biosimilars through education

Biosimilars/Research | Posted 12/02/2021

The process of introducing biosimilars into clinical practice is complex and involves many stakeholders. There are different strategies that healthcare systems have adopted to incorporate biosimilars into patient care. Regulators, payers, pharmacists, and physicians need adequate knowledge in order to be effective components of this process. Previous research in the region has shown a high prevalence of lack of understanding and major safety concerns on the use of biosimilars [1].

Understanding and minimizing injection-site pain for biologicals

Biologicals have revolutionized treatment across a range of immune and inflammatory-related diseases and have had considerable impact on the health economy. Switching to a biosimilar has proven to be an effective, safe and pharmacoeconomically advantageous strategy for health systems.

Clinical evidence for interchangeability of biosimilars in the US

In the United States, the Food and Drug Administration (FDA) approval of a biosimilar is based on the ‘totality of the evidence’ from comparative analytical and functional assessments and comparative clinical (pharmacology, immunogenicity, safety and efficacy) assessments that support a conclusion of biosimilarity [1]. An approved biosimilar can also be designated as ‘interchangeable’ if it can be concluded that the biosimilar is expected to produce the ‘same clinical result as the reference product in any given patient’ and there is no increased risk in terms of safety or diminished efficacy associated with switching or alternating between the biosimilar and reference product (RP) [2]. With such designation, an interchangeable biosimilar could be substituted for its RP at the pharmacy level where state law allows [2].

How organizations worldwide are producing HTA reports for biosimilars

The vital contribution of Health Technology Assessment (HTA) is well recognized and consolidated in scientific and technological practice; however, there is still no generally accepted position on its utilization in relation to biosimilars.

Influence of local policy measures and practices on biosimilar/originator market dynamics in Germany

Biosimilars/Research | Posted 15/01/2021

In Europe, the individual Member States are responsible for designing policies that regulate the market entry and use of pharmaceuticals. This decentralized approach has been found to contribute to variations in biosimilar uptake across countries, and even within countries, as was investigated for tumour necrosis factor-alfa (TNF-α) inhibitor biosimilars in Sweden [1, 2]. In Germany, biosimilar market shares are also known to vary at the regional level. This was studied by Blankart et al. for erythropoiesis-stimulating substances, filgrastim and somatropin, and variations in biosimilar market shares were partly attributed to the presence of explicit regional cost-control measures, such as quota regulations [3]. Differences in the uptake of biosimilars have also been described in Germany for the class of TNF-α inhibitors, although reasons behind this variable uptake have not been examined in detail [4].
