Abstract
BACKGROUND Healthcare sustainability is a global challenge. Various value-driven healthcare strategies have been implemented by Singapore's national health technology assessment (HTA) agency, the Agency for Care Effectiveness (ACE). Considering the high and growing expenditure on biologics, strategies have been implemented to drive the use of biosimilars. As Singapore has reached the 5-year mark since the subsidy listing of the first monoclonal antibody biosimilar infliximab, this review aimed to evaluate the impact of these strategies on the changes in adoption rates, utilisation, spending and cost savings for biosimilars in the public healthcare sector. METHODS A retrospective cross-sectional study was conducted using aggregated drug utilisation data from all public healthcare institutions. Five monoclonal antibodies with biosimilars, namely infliximab, adalimumab, trastuzumab, rituximab and bevacizumab, were included in this study. The outcomes evaluated were the monthly trends for utilisation volume, proportion attributed to biosimilar use, and drug spending up to December 2022. The simulated cost savings associated with biosimilar adoption were also reported. RESULTS After subsidy implementation, an upward trend in biosimilar use and proportion attributed to biosimilar adoption was observed, while spending reduced substantially. The adoption rate of most biosimilars reached more than 95% within 1 year of listing. Drugs with more than one approved biosimilar brand at the time of subsidy listing reported substantial price reductions of over 80%. Overall, spending for the five monoclonal antibodies have significantly reduced after biosimilar subsidy listing, with an estimated cumulative cost savings of $136 million over 5 years. CONCLUSION Value-driven healthcare strategies implemented in Singapore's public healthcare institutions have contributed to high adoption rates of biosimilars and have improved affordable access through lower treatment costs. This in turn has led to significant cost savings to the healthcare system.

Rieger C, Dean JA, Hall L, Vasquez P, Merlo G. Barriers and Enablers Affecting the Uptake of Biosimilar Medicines Viewed Through the Lens of Actor Network Theory: A Systematic Review. BioDrugs 2024; 38:541-555. [PMID: 38879730 PMCID: PMC11247062 DOI: 10.1007/s40259-024-00659-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/26/2024] [Indexed: 07/16/2024]
Abstract
BACKGROUND AND OBJECTIVE Biosimilars represent an opportunity to realise savings against the costs of innovative medicines. Despite efforts made by stakeholders, there are numerous barriers to the uptake of biosimilars. To realise the promise of biosimilars reducing costs, barriers must be identified, understood, and overcome, and enablers magnified. The aim of this systematic review is to summarise the enablers and barriers affecting uptake of biosimilars through the application of a classification system to organise them into healthcare professional (HCP), patient, or systemic categories. METHODS A systematic literature search was performed in PubMed, Scopus, CINAHL, eConlit, and Embase. Included were primary research studies published in English between Jan 2017 through June 2023 focused on enablers and barriers affecting uptake of biosimilars. Excluded studies comprised comparisons of biosimilar efficacy and safety versus the reference biologic. One reviewer extracted data that included classification of barriers or enablers, the sub-classification, and the identification of the degree of agency associated with the actor through their role and associations as a mediator within their network, through the application of Actor Network Theory. The data were validated by a second reviewer (PV). RESULTS Of the 94 studies included, 59 were cross-sectional, 20 were qualitative research, 12 were cohort studies, and three were economic evaluations. Within the review, 51 of the studies included HCP populations and 35 included patients. Policies and guidelines were the most cited group of enablers, overall. Systemic enablers were addressed in 29 studies. For patients, the most frequently cited enabler was positive framing of a biosimilar, while for HCPs, cost benefit was the most frequently noted enabler. The most frequently discussed systemic barrier to biosimilar acceptance was lack of effective policies or guidelines, followed by lack of financial incentives, while the most significant barriers for HCPs and patients, respectively, were their lack of general knowledge about biosimilars and concerns about safety and efficacy. Systemic actors and HCPs most frequently acted with broad degree of agency as mediators, while patient most frequently acted with a narrow degree of agency as mediators within their networks. CONCLUSIONS Barriers and enablers affecting uptake of biosimilars are interconnected within networks, and can be divided into systemic, HCP, and patient categories. Understanding the agency of actors within networks may allow for more comprehensive and effective approaches. Systemic enablers in the form of policies appear to be the most effective overall levers in affecting uptake of biosimilars, with policy makers advised to give careful consideration to appropriately educating HCPs and positively framing biosimilars for patients.

Abstract
INTRODUCTION After 17 years on the market, biosimilar medicines have contributed significantly to the sustainability of healthcare in Spain, providing cost-effective treatment options and savings of more than €1 billion by 2022 alone. To fully exploit this potential and meet the European pharmaceutical strategy's objectives of increased access and a resilient supply chain, Member States need to optimize their biosimilars policies. AREAS COVERED We conducted an exhaustive review of biosimilar medicines in Spain, first describing their regulatory framework. Biosimilar policies at both national and regional level have been collected and updated figures on the biosimilars market are provided based on official data. Knowledge and acceptance of biosimilar medicines among patients and medical societies based on biosimilar positioning documents is reviewed. National evidence on the contribution of biosimilars to savings and sustainability is also included in this study. EXPERT OPINION In Spain, there is a need to further build confidence in biosimilars, develop a strong national biosimilars policy and address regional variability, improve public procurement and adapt clinical practice guidelines following the commercialization of biosimilars. By implementing a holistic and evidence-based policy, Spain can fully exploit the benefits of biosimilar medicines and ensure better and equitable access across the healthcare system.

Abstract
Background The availability of biosimilar medicines in Southern European markets has allowed purchasing biologics at a lower cost for healthcare systems. However, the capacity to seize this cost-reduction opportunity in the long run depends on fostering a sustainable competitive environment for all the market players involved. Diverse policies and information campaigns have been launched in Italy, Portugal and Spain to support uptake of "best-value" biologics (BVB). Despite these measures, the utilization of lower-cost biologics in certain regions is low, especially when it comes to the treatment of chronic conditions. Objective We aim to identify biosimilar uptake determinants in hospital environments in Italy, Portugal and Spain, using the class of TNF-alpha inhibitors as an example. Methods This is a mixed-methods study based on (1) the quantitative analysis of regional uptake data for TNF-alpha inhibitor biosimilars and (2) the qualitative processing of semi-structured interviews capturing experts' views on uptake determinants for biosimilars. Results The organization of multi-stakeholder information campaigns supporting TNF-alpha inhibitor biosimilars use in Italy, Portugal and Spain has resulted in an increased familiarity of healthcare professionals and patients with the prescription/use of these products. However, barriers persist that impede high biosimilars uptake, especially in chronic patient populations eligible for a switch. These are: (1) the late publication of position statements on biosimilars interchangeability by regulatory health authorities; (2) the vague positioning of (national/regional) health authorities on best switching practices (including multiple biosimilar-to-biosimilar switches); (3) the existence of policy frameworks that do not necessarily support the initiation of switching protocols; (4) the establishment of sometimes inefficient purchasing procedures that limit biosimilars potential to compete for market shares. Diverse approaches taken regionally to address these barriers have contributed to heterogeneous TNF-alpha inhibitor biosimilars uptake across Southern Europe. Conclusion Our research signaled the limited reach of biosimilar policies implemented locally, if not supported by a national policy framework. This study highlights the need for the coordinated implementation of policy measures fostering biosimilars use at the regional and national level in Italy, Portugal and Spain. These measures should account for the particularities of off-patent biologic and biosimilar markets and should jointly address supply- and demand-side challenges.

Front Pharmacol 2023; 14:1151764. [PMID: 37153785 PMCID: PMC10160635 DOI: 10.3389/fphar.2023.1151764] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Accepted: 04/10/2023] [Indexed: 05/10/2023] Open
Abstract
Background: Factors like the number of biosimilar competitors and competitive pricing strategies from originator companies may influence price competition and biosimilar uptake. Objective: The aim of this study was to analyze multiple facets of biosimilar competition of TNF-alpha inhibitors in Europe by exploring the existence of a biosimilar first-mover advantage, pricing strategies of originator companies, and the evolution in patient access. Methods: Sales and volume data on biosimilar and originator infliximab, etanercept, and adalimumab between 2008 and 2020 were provided by IQVIA. Countries included 24 European Union Member States, Norway, Switzerland, United Kingdom, Serbia, and Bosnia and Herzegovina. Sales value was expressed as ex-manufacturer price per defined daily dose (DDD), and volume data were transformed into the number of DDDs per 1,000 inhabitants per day. Descriptive analyses were conducted based on the evolution in price per DDD, trends in biosimilar and originator market shares and utilization trends. Results: Market entry of the first biosimilars of infliximab and adalimumab resulted in a decrease of the volume-weighted average price (VWAP) per DDD by 13.6% and 0.9% on average, whilst the second biosimilars resulted in a decrease by 26.4% and 27.3%, respectively. The first and second etanercept biosimilars generated a similar decrease in the VWAP per DDD by 9.3% and 9.1% on average, respectively. Average market share captured by the first biosimilars was at least twice as large as the second biosimilars for all molecules. In addition, sharp reductions in price per DDD of Humira® in most countries indicated a pricing strategy resulting in low uptake of adalimumab biosimilars. Lastly, utilization of infliximab, etanercept, and adalimumab following biosimilar entry increased by an average of 88.9%, 14.6%, and 22.4%, respectively. However, introduction of (multiple) biosimilar competitors did not necessarily translate into increase in treatment access for all three molecules across some European countries indicating a shift in utilization from one molecule towards the other(s). Conclusion: Overall, this study revealed that biosimilar entry results in increased utilization and price reduction, although at a heterogenous rate among TNF-alpha inhibitors. Observed trends in market shares indicate a biosimilar first-mover advantage whereas pricing strategies considered to be anti-competitive can limit market uptake.

Abstract
Background: The level of competition achieved following biosimilars market availability varies by country, care setting and molecule. Hence, biosimilars contribution to attaining price reductions and extended access to treatments can also vary. Objective: The aim of this study is to capture market dynamics for tumor necrosis factor (TNF)-alpha inhibitors and competing molecules in Southern European markets (2011-2020), and to evaluate the benefits of the competition generated by the availability of biosimilars. Methods: This study is based on a literature review examining market characteristics for TNF-alfa inhibitors and competing immunomodulator molecules, and on the quantitative analysis of market data for these molecules in Italy, Portugal and Spain. Results: Following biosimilars availability in Italian, Portuguese and Spanish markets, there has been an expansion in the overall access to TNF-alfa inhibitor pharmaceuticals. Further, savings have been generated within the TNF-alfa inhibitors class even after the increased use of these molecules. However, the potential of infliximab, etanercept and adalimumab biosimilars to generate price competition outside of their own drug class appeared limited in the studied markets. Considering this limitation and that shifts towards on-patent and higher-cost therapies have occurred after TNF-alfa inhibitor biosimilars availability, the importance of investing in biosimilars development for still on-patent immunology biologics is emphasized. Conclusion: This study highlights the need for policies that do not only seek higher utilization of biosimilars, but that also support a sustainable market for these products. This is expected to foster the future development of biosimilar medicines.

Abstract
BACKGROUND AND OBJECTIVE Pharmaceutical policies are generally based on the assumption that involved stakeholders make rational decisions. However, behavioral economics has taught us that this is not always the case as people deviate from rational behavior in rather predictable patterns. This scoping review examined to what extent behavioral concepts have already been applied in the pharmaceutical domain and what evidence exists about their effectiveness, with the aim of formulating future applications and research hypotheses on policymaking for best-value biologicals. METHODS A scoping literature review was conducted on the evidence of behavioral applications to pharmaceuticals. Scientific databases (Embase, MEDLINE, APA PsycArticles, and Scopus) were searched up to 20 October, 2021. RESULTS Forty-four full-text scientific articles were identified and narratively described in this article. Pharmaceutical domains where behavioral concepts have been investigated relate to influencing prescribing behavior, improving medication adherence, and increasing vaccination uptake. Multiple behavioral concepts were examined in the identified studies, such as social norms, defaults, framing, loss aversion, availability, and present bias. The effectiveness of the applied interventions was generally positive, but depended on the context. Some of the examined interventions can easily be translated into effective policy interventions for best-value biological medicines. However, some applications require further investigation in a research context. CONCLUSIONS Applications of behavioral economics to pharmaceutical policymaking are promising. However, further research is required to investigate the effect of behavioral applications on policy interventions for a more sustainable market environment for best-value biological medicines.

Abstract
DISCLAIMER In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE With the growing availability of biosimilars on the global market, clinicians and pharmacists have multiple off-patent biological products to choose from. Besides the competitiveness of the product's price, other criteria should be considered when selecting a best-value biological. This article aims to provide a model to facilitate transparent best-value biological selection in the off-patent biological medicines segment. SUMMARY The presented model was developed on the basis of established multicriteria decision analysis tools for rational and transparent medicine selection, ie, the System of Objectified Judgement Analysis and InforMatrix. Criteria for the model were informed by earlier research, a literature search, and evaluation by the authors. The developed model includes up-to-date guidance on criteria that can be considered in selection and provides background on the allocation of weights that may aid hospital pharmacists and clinicians with decision-making in practice. Three main categories of criteria besides price were identified and included in the model: (1) product-driven criteria, (2) service-driven criteria, and (3) patient-driven criteria. Product-driven criteria include technical product features and licensed therapeutic indications. Service-driven criteria consist of supply conditions, value-added services, and environment and sustainability criteria. Patient-driven criteria contain product administration elements such as ease of use and service elements such as patient support programs. Relative weighting of the criteria is largely context dependent and should in a given setting be determined at the beginning of the process. CONCLUSION The practical model described here may support hospital pharmacists and clinicians with transparent and evidence-based best-value biological selection in clinical practice.

Qualitative Analysis of the Design and Implementation of Benefit-Sharing Programs for Biologics Across Europe. BioDrugs 2022; 36:217-229.

Abstract
Background To encourage the rational prescribing of biologics, payers across Europe have experimented with the implementation of benefit-sharing programs. Benefit-sharing programs are incentive programs that promote the use of ‘best-value’ off-patent biologics and biosimilars by driving changes in prescribing practices. The aim of these programs is to generate savings that can be shared among stakeholders involved (e.g. health authorities/payers, health care professionals, hospital managers/administration) and are generally used to improve the quality of health care and to increase patients’ access to innovative services and medicines. However, the scarcity of information concerning the design, implementation and outcomes of benefit-sharing programs limits the transfer of knowledge to institutions aiming to adopt these types of incentive schemes in the future. Objective The aim of our study was to map benefit-sharing experiences across Europe, to compare their design and implementation characteristics and to assess the impact of the different benefit-sharing strategies on the use of ‘best-value’ biologics. Method Our approach was based on a literature review and on semi-structured interviews with payers/insurers, regulators, health care professionals and industry representatives. Results Our analysis revealed variable design characteristics for benefit-sharing programs, depending on the organization of the health care system, the specific timeframe, the care setting and the policy environment. All these aspects can influence the robustness of benefit-sharing initiatives and their potential to stay in effect over time. We also noted a generalized lack of transparency regarding the distribution of savings and how they are reinvested. This lack of transparency has raised questions on how to optimally implement benefit-sharing in the future. Conclusions To realize the full potential of benefit-sharing programs, we identify the importance of (i) setting up and timely monitoring success indicators for these programs; (ii) including quality of care and access to care parameters as success indicators; (iii) establishing clear pathways for the transparent redistribution/reinvestment of savings and (iv) transparently communicating with patients about the outcomes of benefit-sharing programs.

Abstract
Background and objectives: Biosimilar medicines have been on the European market for 15 years. Despite the extensive and positive experience with biosimilars across Europe, their uptake remains limited in Belgium. One of the possible factors limiting uptake in clinical practice is the inadequate understanding and lack of trust in biosimilars among patients. This study aimed to assess the level of knowledge and perceptions about biosimilar medicines among Belgian patients in the ambulatory care. Methods: This study consisted of online questionnaires among Belgian patients in the ambulatory care (i.e., rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, Crohn’s disease, ulcerative colitis, diabetes mellitus type I and II). The results were collected between December 2020 and February 2021. The data were analyzed with descriptive and inferential statistics. Results: In total, 657 patients across all disease areas of interest participated in this study. Only 38% of patients had heard of biosimilars before. Of those patients, most (58%) were aware that biosimilars are as safe and effective as their reference product. The vast majority of respondents (68%) would agree with transitioning to a biosimilar if their physician prescribed it, only 3% would never agree with a transition to a biosimilar. If a physician would propose to change their current originator biological therapy with its biosimilar, nearly all patients (95%) want their physician to explain the decision and inform them. For additional information about biosimilars, Belgian patients prefer brochures or folders (41%), or available resources on the internet (35%). Physicians were indicated as the preferred source of information (95%), followed by pharmacists (51%), academia (39%), and patient associations (35%). Most patients require information regarding the safety and efficacy (78%), price and reimbursement (64%), and the clinical development process (56%) of the biosimilar. Conclusion: Belgian patients require information about biosimilar medicines. However, most patients are open and positive towards transitioning their current biological therapy with its biosimilar if sufficiently supported by their healthcare providers.

[PMID: 34966285 PMCID: PMC8710743 DOI: 10.3389/fphar.2021.795002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Accepted: 11/30/2021] [Indexed: 12/03/2022] Open
Abstract
Background: The aim of this study was to investigate the impact of selected legislative initiatives and their implementation for off-patent medicinal products in Slovakia compared with the rest of the Visegrád Group (V4 countries). Methods: We analyzed the development of applications for the reimbursement of generic and biosimilar drugs. Particular emphasis was placed on a) the availability and penetration of biosimilars from 2006 to 2020 in Slovakia, b) a comparative analysis of biosimilars in V4 countries based on the national reimbursement lists of medicinal products for August 2021. Data relating to the sales of generic and biosimilar medicines in Czechia, Hungary, Poland, and Slovakia were based on the IQVIA MIDAS MAT July 2021. Results: The number of applications for the reimbursement of generic drugs decreased from 296 in 2016 to 165 in 2020. In financial terms, the sales of generic medicines in Slovakia increased from 21.7% in 2015 to 22.3% in 2020. Over the same period, the sales of generic drugs in Poland fell from 40.4% in 2015 to 35.0% in 2020, from 26.2 to 22.1% in Hungary, and from 29.6 to 20.4% in Czechia. When considering the 66 biosimilars registered by the European Medicines Agency 38 drugs (58%) were available on the Slovak market as of August 1, 2021; this compared to 32 drugs (48%) in Poland, 38 drugs (58%) in Hungary, and 40 drugs (61%) in Czechia. In financial terms, the sales of biosimilars in Slovakia increased from 0.94% in 2015 to 2.00% in 2020. Over the same period, the sales of biosimilars in Poland increased from 0.59% in 2015 to 1.29% in 2020, from 0.72 to 2.23% in Hungary, and from 0.76 to 2.15% in Czechia. Conclusion: To intensify the use of generic and biosimilar medicines, we suggest the comprehensive re-evaluation of combinations of the three-threshold entry, the amount of mandatory price reductions, and external reference pricing requirements (as the average of the three lowest prices among the official prices of a medicinal product in other Member States) for generic and biosimilar drugs. We also suggest cancellation of the exception from the fixed co-payment of the insured.

Abstract
INTRODUCTION Five years after the launch of the first infliximab biosimilar, biologics have found their place in the treatment of chronic inflammatory conditions, but there are remaining questions. This is a review of the introduction of antibody biosimilars in Europe; the reasons for their success and how biosimilar hesitancy was quailed. AREAS COVERED We provide an overview of the concepts of biosimilarity, extrapolation, and interchangeability, using examples in rheumatology and gastroenterology for illustration. A review of the evidence collected from switching studies using robust designs is included. Remaining questions such as 'inter-switching' are also discussed. EXPERT OPINION Biosimilars have democratized access to powerful medicines. Efficacy and safety studies provided reassuring data, but knowledge gaps persist. The availability of so-called 'bio-betters' might open new avenues and change clinical practice.

Abstract
Background and objective: Best-value biological medicines may generate competition in the off-patent biologicals market, resulting in having more resources available to provide patients with access to necessary medicines while maintaining high-quality care. Belgium is a country known to have low biosimilar market shares, suggesting a malfunctioning market for off-patent biologicals. This study aims to gain an in-depth understanding of the Belgian off-patent biologicals market, by looking at the evolution in volumes and costs of the relevant products in the market. Methods: This study included a combination of quantitative and qualitative research methods. The quantitative part of this study consisted of the analysis of market data obtained by the National Institute for Health and Disability Insurance (NIHDI) for all relevant products in the Belgian off-patent biologicals market (i.e. TNF-inhibitors, insulins, granulocyte colony-stimulating factors, epoetins, rituximab, trastuzumab). In addition, for the qualitative part of this study, semi-structured interviews with Belgian stakeholders were conducted between December 2019 and March 2020. Results: Belgian market data and stakeholder perceptions suggest a suboptimal market environment for off-patent biological and biosimilar medicines. Shifts are observed after loss of exclusivities of originator biologicals toward second-generation products or new therapeutic class products, at a higher cost and often limited added value. Moreover, cost reductions for off-patent biologicals after biosimilar market entry are mainly determined by mandatory price reductions applicable to both originator and biosimilar products, and not by lower prices induced by competition. For products used in the retail setting, significant mandatory price reductions for both originator and reference products with low biosimilar volumes were pointed out as the main reasons for the lack of price competition. For products dispensed in hospitals, the hospital financing system is important. First, it does not always encourage the use of lower cost alternatives. Second, competition mainly takes place at the level of confidential discounts in tenders. Most interviewees acknowledged the lack of a competitive environment, which is not supportive of a sustainable Belgian off-patent biologicals market. Conclusion: Market data and stakeholder perceptions indicate that the sustainability of the Belgian market for off-patent biologicals is challenged. A sustainable market ensures access to biological therapies now and in the future.

Abstract
Background Regions within England, Scotland and Wales show variation in rate of adoption of biosimilar infliximab and etanercept. Objectives This study aims to examine how local decisions and practices in regions within England, Scotland and Wales might explain initial variation in market dynamics of biosimilar and originator infliximab and etanercept. Methods Market data provided by the National Health Service (NHS) on biosimilar and originator infliximab and etanercept uptake were analysed for the 10 historical regions of England, 14 health boards in Scotland and 7 health boards in Wales (2015–2018). Findings were discussed in ten semi-structured interviews: on a national level with an industry representative (1), on a regional level with NHS employees in England (6), Scotland (1) and Wales (1), and on a local level with a representative of a clinical commissioning group in England (1). Results Tenders for infliximab and etanercept in England, Scotland and Wales have consistently resulted in a biosimilar as the best value biological. Early and late biosimilar adopters are seen, with overall convergence towards high biosimilar market shares over time. Qualitative results suggest that biosimilar adoption was positively influenced by (a) a price difference between biosimilar and originator product making it worthwhile to switch patients; (b) a good relationship between commissioner and provider in England resulting in gain share agreements; (c) leadership on biosimilars in regional NHS offices in England or Scottish and Welsh health boards; (d) key opinion leaders or leading hospitals that start using biosimilars early and gain experience. Conclusions This study has shown that the savings potential drives biosimilar use. Regions with a proactive attitude, good stakeholder relationships, and clinician engagement were identified as early adopters.

Abstract
Background: From October 2018, adalimumab biosimilars could enter the European market. However, in some countries, such as Netherlands, high discounts reported for the originator product may have influenced biosimilar entry. Objectives: The aim of this paper is to provide a European overview of (list) prices of originator adalimumab, before and after loss of exclusivity; to report changes in the reimbursement status of adalimumab products; and discuss relevant policy measures. Methods: Experts in European countries received a survey consisting of three parts: 1) general financing/co-payment of medicines, 2) reimbursement status and prices of originator adalimumab, and availability of biosimilars, and 3) policy measures related to the use of adalimumab. Results: In May 2019, adalimumab biosimilars were available in 24 of the 30 countries surveyed. Following introduction of adalimumab biosimilars, a number of countries have made changes in relation to the reimbursement status of adalimumab products. Originator adalimumab list prices varied between countries by a factor of 2.8 before and 4.1 after loss of exclusivity. Overall, list prices of originator adalimumab decreased after loss of exclusivity, although for 13 countries list prices were unchanged. When reported, discounts/rebates on originator adalimumab after loss of exclusivity ranged from 0% to approximately 26% (Romania), 60% (Poland), 80% (Denmark, Italy, Norway), and 80–90% (Netherlands), leading to actual prices per pen or syringe between €412 (Finland) and €50 – €99 (Netherlands). To leverage competition following entry of biosimilar adalimumab, only a few countries adopted measures specifically for adalimumab in addition to general policies regarding biosimilars. In some countries, a strategy was implemented even before loss of exclusivity (Denmark, Scotland), while others did not report specific measures. Conclusion: Even though originator adalimumab is the highest selling product in the world, few countries have implemented specific policies and practices for (biosimilar) adalimumab. Countries with biosimilars on the market seem to have competition lowering list or actual prices. Reported discounts varied widely between countries.

Abstract
Introduction: Little is known about market access to biosimilars from a health economic perspective, except for studies that compute the budget impact of biosimilar use. Areas covered: This comprehensive health economic guide to the market access of biosimilars focuses on the role of biosimilars in pharmaceutical innovation and competition, the objective of biopharmaceutical policy, the budget impact of biosimilars, and the cost-effectiveness of biologic therapy in the presence of biosimilars. Expert opinion: We argue that the objective of biopharmaceutical policy in a health system should be to create a competitive and sustainable market for off-patent reference biologics, biosimilars, and next-generation biologics that makes biologic therapy available to patients at the lowest cost. Market access of biosimilars can contribute to this objective as a result of the lower price of biosimilars and price competition with alternative therapies. The resulting improvement in the cost-effectiveness of biologic therapy needs to be accounted for by revisiting reimbursement decisions and conditions. When examining the cost-effectiveness of biologic therapy following patent expiry, stakeholders need to consider residual uncertainties at the time of biosimilar marketing authorization, the nocebo effect, market entry of a second-generation reference biologic with a different administration form than the biosimilar, and value-added services.

Learnings from Regional Market Dynamics of Originator and Biosimilar Infliximab and Etanercept in Germany. Pharmaceuticals (Basel) 2020; 13:E324. [PMID: 33096709 PMCID: PMC7590006 DOI: 10.3390/ph13100324] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/17/2020] [Accepted: 10/17/2020] [Indexed: 12/05/2022] Open
Abstract
Drug budget and prescription control measures are implemented regionally in Germany, meaning that the uptake of pharmaceuticals, including biosimilars, can vary by region. We examine regional market dynamics of tumor necrosis factor alpha (TNFα) inhibitor originators and biosimilars in Germany and studied the influence of biosimilar policies on these dynamics. This study is based on: (1) a literature review in which German biosimilar policies are identified, (2) the analysis of dispensing data (2010-2018) for the class of TNFα inhibitors, and (3) ten semi-structured interviews investigating prescribers' and insurers' views on factors potentially influencing biosimilar uptake. The analysis of biosimilar market shares of infliximab and etanercept revealed wide variations across the 17 German Regional Associations of Statutory Health Insurance Accredited Physicians (PA regions). Quantitative analyses indicated that biosimilar market shares for infliximab and etanercept were significantly lower in former East Germany when compared to former West Germany regions. Through qualitative interview analyses, this study showed that the use of infliximab and etanercept biosimilars across Germany is primarily influenced by (1) the regional-level implementation of biosimilar quotas and the presence of monitoring/sanctioning mechanisms to ensure adherence to these quotas, (2) the different insurer-manufacturer discount contracts, and (3) gainsharing arrangements established at the insurer-prescriber level.

Abstract
Objectives: To analyse the market shares of biosimilars in Slovakia and to calculate the potential cost-savings from the use of biosimilars in Slovakia based on two different data sources. Methods: National reimbursement lists from the Czech Republic, Hungary, Poland and Slovakia were used for analyzing the availability of biosimilars with public funding. In addition, the reimbursement dossiers of biosimilars, the justifications of reimbursement decisions by the Slovak Ministry of Health, and final reimbursement decrees, which are published on the webpage of the Slovak Ministry of Health, were utilized for this study. Reimbursement decisions regarding biosimilars by the Slovak Ministry of Health from 2006 to August 2019 were considered and the detailed utilization of biosimilars in 2018 was analyzed based on data from the State Institute for Drug Control. The study was validated based on data from the Slovak National Health Information Center. Results: Fifty four biosimilars were approved by the European Medicines Agency (EMA) in August 2019. Of the total group of licensed biosimilars on the market, 29 biosimilars (54%) were available in the Czech Republic, 28 biosimilars (52%) were available in Poland, and 27 biosimilars (50%) were available in Hungary and 24 biosimilars (44%) were available in Slovakia. Our analysis, based on the data provided by distributors of medicinal products to the State Institute for Drug Control, revealed that the health fund in Slovakia could have saved 35 to 50 million euros per year if biosimilars with marketing authorisations had been available on the Slovak market. The calculations assumed a 25-35% price decrease against the original biological medical products, and that there would be no increase in the utilization of biosimilars in Slovakia. Conclusions: To achieve significant improvement in patient access to biosimilars in Slovakia, a top-down approach establishing targets and quotas for the procurement of biosimilars should be applied.

Front Pharmacol 2020; 11:970. [PMID: 32733238 PMCID: PMC7363801 DOI: 10.3389/fphar.2020.00970] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2020] [Accepted: 06/15/2020] [Indexed: 12/18/2022] Open
Abstract
Objective To compare the market dynamics of biosimilar infliximab among four Organization for Economic Cooperation and Development (OECD) countries (UK, France, Japan, and Korea) where supply-side and demand-side policies varied greatly, given high and growing expenditure on biological medicines to treat immunological diseases across countries. Methods A quarterly dataset covering October 2012 to March 2018 was constructed from the MIDAS-IQVIA International database. The sales value (in USD) and volume (in standard units) of originator infliximab and biosimilar products and their relative price in each country were compared. Results With the introduction of biosimilars, the sales value of infliximab increased approximately 2.5 times in Korea, whereas it only slightly increased (1.2 times for France and the UK) or decreased (0.9 for Japan) in other countries. While stable market size dynamics were observed in the other countries, an escalating market size, attributable to the increase in originator infliximab, was observed in Korea. In the UK and France, which have implemented demand-side policies, the sales volume of originator infliximab appreciably decreased after the entry of biosimilar infliximab while that of biosimilars increased; however, in Korea, which has supply-side policies based on price-linking with few demand-side policies, the volume of originator infliximab actually increased by 70% alongside a very limited increase in biosimilar infliximab. The lowest price ratio between biosimilar and originator infliximab was found in Japan, at 68%. In France and Korea, the ex-factory prices of biosimilar infliximab were 99 and 95%, respectively, of the originator infliximab price. In the UK, the ex-factory price of biosimilar infliximab started at 87% of that of originator infliximab and then decreased to 80% as the market matured. However, actual price differences might differ. Conclusion The uptake of biosimilar infliximab varied greatly, and in contrast to the UK, France, and Japan, the introduction of biosimilar infliximab resulted in market expansion in Korea, which might be explained by a lack of demand-side policies in Korea. Both supply- and demand-side measures are necessary for health authorities to achieve desired savings from the availability of biosimilars.

Abstract
Background Diverging approaches towards market entry and uptake of biosimilars, even within a country, leads to regional variation in biosimilar use. This is the case in Sweden, where the 21 county councils control the healthcare budget and offer regional guidance. Objectives This study aimed to analyse the market dynamics of originator and biosimilar etanercept (outpatient setting) in the different counties of Sweden, and examine the influence of local policy measures and practices, in addition to national policy. Methods This study was performed in three steps: (1) a structured review of the literature on (biosimilar) policies in Sweden; (2) analysis of market data on the counties’ originator and biosimilar etanercept uptake (quarter two 2012 to quarter four 2017) provided by IQVIA™; and (3) discussion of findings in face-to-face semi-structured interviews with the national pricing and reimbursement agency, key experts in the county councils of Skåne, Västra Götaland and Stockholm, and an industry representative. Results Notwithstanding the existence of a national managed entry agreement for etanercept, wide variations in biosimilar market shares between counties were observed (40–82% in 2017). Over time, early and late adopters of biosimilar etanercept can be distinguished. In quarter four 2017, biosimilar market shares of all counties slightly decreased in accordance with the lower priced originator product from 1 October 2017. As prescriptions for treatment with etanercept are often provided for a year, two approaches are possible to switch patients: active pullback of prescriptions resulting in additional workload, or wait until the patient’s next visit. Qualitative analysis indicated that the choice to use the biosimilar or the originator product depends on differences in rebated prices of the biosimilar and originator product, the presence of key opinion leaders, local guidelines, and financial streams and local gainsharing arrangements. Our estimates of current rebated prices and costs after gainsharing for the county councils and Government reveal only limited price differences between products. Conclusions Regional variations in use of biosimilar etanercept can be seen although prices are coordinated nationally. This suggests that counties react differently to price differences and highlights the role of local policy and attitudes of stakeholders towards biosimilars and switching. It seems that some counties are hesitant to switch patients, as it is associated with an increased administrative workload that might not be compensated for by savings associated with a lower priced product.

Mansell K, Bhimji H, Eurich D, Mansell H. Potential cost-savings from the use of the biosimilars filgrastim, infliximab and insulin glargine in Canada: a retrospective analysis. BMC Health Serv Res 2019; 19:827. [PMID: 31718624 PMCID: PMC6852752 DOI: 10.1186/s12913-019-4680-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Accepted: 10/25/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND In 2014 and 2015, biosimilars for the drugs filgrastim, infliximab, and insulin glargine were approved for use in Canada. The introduction of biosimilars in Canada could provide significant cost savings for the Canadian healthcare system over originator biologic drugs, however it is known that the use of biosimilars varies widely across the world. The aim of this study was to estimate the use of biosimilars in Canada and potential cost-savings from their use. METHODS We performed a retrospective analysis of Canadian drug purchases for filgrastim, infliximab, and insulin glargine from July 2016 to June 2018. This was a cross-sectional study and the time horizon was limited to the study period. As a result, no discounting of effects over time was included. Canadian drugstore and hospital purchases data, obtained from IQVIA™, were used to estimate the costs per unit and unit volume for biosimilars and originator biologic drugs within each province. Potential cost-savings were calculated as a product of the units of reference originator product purchased and the cost difference between the originator biologic and its corresponding biosimilar. RESULTS The purchase of biosimilars varied by each province in Canada, ranging from a low of 0.1% to a high of 81.6% of purchases. In total, $1,048,663,876 Canadian dollars in savings could have been realized with 100% use of biosimilars over the originator products during this 2 year time period. The potential savings are highest in the province of Ontario ($349 million); however, even in smaller markets (PEI and Newfoundland), $28 million could have potentially been saved. Infliximab accounted for the vast majority of the potential cost-savings, whereas the purchases of the biosimilar filgrastim outpaced that of the originator drug in some provinces. In sensitivity analyses assuming only 80% of originator units would be eligible for use as a biosimilar, $838 million dollars in cost savings over this two-year time period would still have been realized. CONCLUSIONS The overall use of biosimilar drugs in Canada is low. Policy makers, healthcare providers, and patients need to be informed of potential savings by increased use of biosimilars, particularly in an increasingly costly healthcare system.
