Consensus-Based Overarching Principles and Recommendations on the Use of Biosimilars in the Treatment of Inflammatory Arthritis in the Gulf Region. BioDrugs 2024; 38:449-463. [PMID: 38402494 PMCID: PMC11055752 DOI: 10.1007/s40259-023-00642-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/28/2023] [Indexed: 02/26/2024]
Abstract
BACKGROUND Though biologic agents have significantly improved the treatment of inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis), high costs, stringent regulations, strict reimbursement criteria, and existing patents have limited patient access to treatments. While being highly similar in quality, safety, and efficacy to biologic reference products, biosimilars can reduce the financial burden and prevent underutilization of medication. OBJECTIVE The objective of this initiative was to develop an evidence-based consensus of overarching principles and recommendations aimed at standardizing the use of biosimilars in treating inflammatory arthritis in the Gulf region. METHODS A task force of practicing rheumatologists, a clinical pharmacist, a health economist, patients, regulators, and payors from across the Gulf region developed recommendations and overarching principles based on the outputs of a systematic literature review conducted to address Patient-Intervention-Comparison-Outcome (PICO) questions specific to key challenges regarding the use of biosimilars for the treatment of inflammatory arthritis in the region. As the data before 2017 have been previously reviewed in another publication, the current review focused on data published between January 2017 and August 2022 (PROSPERO ID CRD42022364002). Consensus on each statement required a level of agreement of 70% or greater. RESULTS Consensus was reached for five overarching principles and nine recommendations by the task force. The principles emphasize the importance of improving the awareness, understanding, and perception of biosimilars, as well as the need for regulated regional real-world data generation and protocols to make biosimilars a viable and affordable treatment option for all patients. The consensus recommendations advocate the need for shared treatment decisions between rheumatologists and patients when considering biosimilars. They further recommend that confirmation of a biosimilar's efficacy and safety in a single indication is sufficient for extrapolation to other diseases for which the reference product has been approved. Finally, there is a need for pharmacovigilance and national health policies governing the adoption and prescription of biosimilars in clinical practice across the region. CONCLUSIONS These are the first consensus recommendations for the Gulf region based on a systematic literature review and Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines, integrating clinical evidence with clinical expertise to optimize decision making for the use of biosimilars in patients with inflammatory arthritis. They were formulated based on predominantly international data because of the limited regional data and therefore can be generalized to serve as recommendations for healthcare professionals in other parts of the world.

Abstract
Biosimilars are biological drugs created from living organisms or that contain living components. They share an identical amino-acid sequence and immunogenicity. These drugs are considered to be cost-effective and are utilized in the treatment of cancer and other endocrine disorders. The primary aim of biosimilars is to predict biosimilarity, efficacy, and treatment costs; they are approved by the Food and Drug Administration (FDA) and have no clinical implications. They involve analytical studies to understand the similarities and dissimilarities. A biosimilar manufacturer sets up FDA-approved reference products to evaluate biosimilarity. The contribution of next-generation sequencing is evolving to study the organ tumor and its progression with its impactful therapeutic approach on cancer patients to showcase and target rare mutations. The study shall help to understand the future perspectives of biosimilars for use in gastro-entero-logic diseases, colorectal cancer, and thyroid cancer. They also help target specific organs with essential mutational categories and drug prototypes in clinical practices with blood and liquid biopsy, cell treatment, gene therapy, recombinant therapeutic proteins, and personalized medications. Biosimilar derivatives such as monoclonal antibodies like trastuzumab and rituximab are common drugs used in cancer therapy. Escherichia coli produces more than six antibodies or antibody-derived proteins to treat cancer such as filgrastim, epoetin alfa, and so on.

Abstract
PURPOSE OF REVIEW Biosimilars were introduced to decrease biologic-related expenditures, but their uptake in inflammatory bowel disease (IBD) remains suboptimal. Herein, we review biosimilar concepts, current products available for IBD treatment, and resources to support biosimilar utilization. RECENT FINDINGS Although a cornerstone of IBD treatment, biologics are costly due to their development. Biosimilars, which are biologic products highly similar to a reference product, aim to decrease these expenditures. Infliximab, adalimumab, and ustekinumab biosimilars are approved for IBD, but uptake remains low due to biosimilar efficacy and safety concerns and delayed market entry. Clinicians can effectively address some of these barriers and help patients and healthcare systems reap the benefits of decreased costs and increased treatment access. Data shows comparable efficacy and safety outcomes with biosimilars in IBD. Several biosimilar products are available and in the pipeline, but efforts are needed from various stakeholders to bolster utilization and generate benefits.

Abstract
OBJECTIVE Transitions to biosimilars are common to reduce the cost burden of biologics. While brand changes can be daunting for patients, few studies have explored patients' experiences with the transitioning process. This study examined rheumatology patients' experiences with a mandatory nationwide brand change to an adalimumab biosimilar. METHODS People with rheumatic diseases involved in the adalimumab transition in Aotearoa New Zealand completed a nationwide online survey. Participants (n = 117, 48% with rheumatoid arthritis) reported their satisfaction with the biosimilar, logistics and supply, information and communication, and availability of support. They also reported what did and did not go well during the transition and provided recommendations for future transitions. RESULTS The mean [SD] satisfaction score with the transition was 6.2 [3.2] on a 0-10 scale, with 10 indicating high satisfaction. Participants were the least satisfied with the support and information from patient support organizations, and training for the device during the transition. Participants were most satisfied with the biosimilar supply, support from pharmacists, and how early they were informed before the transition occurred. After the transition, participants were less satisfied with the device quality, patient support program, biosimilar safety and efficacy, and the provision of alcohol wipes and sharps bins (p < 0.05 for all). Satisfaction with training for the biosimilar device (B = .25, p = .036) predicted overall satisfaction. Participants appreciated less injection pain and the ease of the biosimilar device. The lack of alcohol wipes and loss of the bio-originator support program were viewed negatively. CONCLUSION Future biosimilar transitions should ensure the availability of alcohol wipes, sharps bins, and a comparable patient support program. Patient support organizations could be involved in providing information to patients about the change.

Health Res Policy Syst 2023; 21:68. [PMID: 37415219 DOI: 10.1186/s12961-023-01015-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 06/08/2023] [Indexed: 07/08/2023] Open
Abstract
BACKGROUND The Belgian government has taken several measures to increase the uptake of biosimilars in past years. However, no formal evaluation of the impact of these measures has been made yet. This study aimed to investigate the impact of the implemented measures on biosimilar uptake. METHODS An interrupted time series analysis was performed using an autoregressive integrated moving average (ARIMA) model with the Box-Jenkins method. All data were expressed as defined daily doses (DDD) per month/quarter and obtained from the Belgian National Institute for Health and Disability Insurance (NIHDI). Three molecules were included in the analysis: etanercept (ambulatory), filgrastim (hospital), and epoetin (hospital). A significance level of 5% was used for all analyses. RESULTS In the ambulatory care, the effect of a financial prescriber incentive of 2019 was investigated. After this intervention, 44.504 (95% CI -61.61 to -14.812; P < 0.001) fewer etanercept biosimilar DDDs were dispensed monthly than expected in the absence of the intervention. Two interventions were modelled for biosimilars in the hospital setting. The first intervention of 2016 includes prescription targets for biosimilars and monitoring of hospitals on adequate tendering. The second intervention involves an information campaign on biosimilars. After the first intervention, a small decrease in quarterly epoetin biosimilar uptake of 449.820 DDD (95% CI -880.113 to -19.527; P = 0.05) was observed. The second intervention led to a larger increase in quarterly epoetin biosimilar uptake of 2733.692 DDD (95% CI 1648.648-3818.736; P < 0.001). For filgrastim, 1809.833 DDD (95% CI 1354.797-2264.869; P < 0.001) more biosimilars were dispensed immediately after the first intervention and 151.639 DDD (95% CI -203.128 to -100.150; P < 0.001) fewer biosimilars each quarter after the first intervention. An immediate and sustained increase of 700.932 DDD (95% CI 180.536-1221.328; P = 0.016) in quarterly biosimilar volume was observed after the second intervention. All other parameter estimates were not statistically significant. CONCLUSIONS The results of this study suggest that the impact of past policy interventions to increase the uptake of biosimilars has been variable and limited. A holistic policy framework is required to develop a competitive and sustainable off-patent biologicals market in Belgium.

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
Biologicals have become an integral part of cancer treatment both as therapeutic agents and as supportive care agents. It is important to know that biologics are large, complex molecular entities requiring extensive immunogenicity testing and pharmacovigilance strategies to ensure no immune response is evoked in the body. Oncology's pharmacological market is dominated by biologics; however, their high development and manufacturing costs are burdensome to health care systems. Biologics being the most expensive prescription drugs on the market limit the accessibility for necessary treatment in the case of many patients. As biologics patents expire, the development of biosimilars is underway in an effort to lower costs and enable patients to access new cancer therapies. Regulatory guidelines for biosimilars have now been established and are constantly being revised to address any issues, facilitating their robust development. Moreover, many scientific societies offer guidance to help stakeholders better understand current regulations and biosimilar's safety. Despite the potential cost benefits, lack of knowledge about biosimilars, and the possibility of immunogenicity have created an uncertain environment for healthcare professionals and patients. In this review, we provide an overview of relevant legislation and regulations, pharmacoeconomics, and stakeholder perceptions regarding biosimilars. The article also describes biosimilars in development, as well as the ones currently available on the market.

Abstract
Introduction: The increasing availability of biosimilars can increase patient access to these drugs and reduce the economic burden. Nurses play a key role in the education, administration, pharmacovigilance and management of the side effects of biosimilars. The aim of this study was to assess the knowledge and attitudes of nurses towards biosimilar drugs in different countries. Methods: An international cross-sectional study was conducted from November 2021 to February 2022. The survey was carried out using Computer-Assisted Web Interview (CAWI), sent by the CAWI panel via the website. Results: The results showed that nurses with a greater level of education felt most knowledgeable about biosimilars (χ2 = 105.813, df = 2, p < 0.001). One-third of nurses with a doctorate and a second degree said biosimilars are used in their workplace (χ2 = 48.169, df = 4, p < 0.001); most nurses with a second degree said that they had never heard of biosimilars (41%). Doctorate-level nurses thought knowledge is the key factor to increasing biosimilar uptake (97%). Conclusions: Nurses are not knowledgeable about biosimilars. Most would like to participate in training on biosimilars. This is a very important topic, because biosimilars are constantly evolving in medicine.

Abstract
BACKGROUND AND AIMS Although subcutaneous formulations of infliximab CT-P13 and vedolizumab are registered for treating moderate-to-severe inflammatory bowel disease [IBD], many questions on their use remain unanswered. We set up a multi-stakeholder initiative resulting in a position statement. METHODS Based on publicly available data, statements on subcutaneous infliximab and vedolizumab were developed and reviewed by 45 Belgian IBD physicians in a three-round modified Delphi process. During a consensus meeting, input from 16 IBD patients, nine IBD nurses and two clinical pharmacologists was provided and statements were further discussed, modified and scored. Statements achieving agreement by at least 70% of the IBD physicians were accepted. RESULTS The Delphi process resulted in 79 agreed statements. In patients initiating intravenous therapy, IBD physicians would only consider switching to subcutaneous formulations in patients achieving both clinical and biological response [for Crohn's disease] or both clinical and endoscopic response [for ulcerative colitis]. For patients under maintenance therapy, switching to subcutaneous formulations was only considered in those achieving both clinical and endoscopic response while receiving standard dosing of infliximab or vedolizumab. While awaiting more scientific data, IBD physicians should consider weekly subcutaneous injections or switching back to an intravenous formulation in case of loss of response. Finally, switching to a subcutaneous formulation should always be a shared decision. CONCLUSIONS All stakeholders welcomed subcutaneous infliximab and vedolizumab. However, more scientific data are needed to select the right patients and timing for switching to these newer formulations, and to explore the optimal strategy in case of loss of response.

Knowledge, Attitudes and Practice of Healthcare Providers, Healthcare Regulatory Practitioners and Patients Toward Biosimilars in China: Insights From a Nationwide Survey. Front Pharmacol 2022; 13:876503. [PMID: 35721219 PMCID: PMC9201466 DOI: 10.3389/fphar.2022.876503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 05/13/2022] [Indexed: 11/24/2022] Open
Abstract
Objective: With increasing numbers of biosimilars entering the market or in the approval pipeline in China, understanding the current awareness and attitudes of biosimilars still remains the first step to promote uptake. This study aims to investigate the knowledge, attitudes and practices (KAP) of multiple stakeholders toward biosimilars, including healthcare providers (HCPs), healthcare regulatory practitioners and patients, and to provide practical information for future uptake of biosimilars in China. Methods: This nationwide cross-sectional online survey was conducted in mainland China. The questionnaire with a high level of reliability and validity was designed based on previous studies and clinical questions in the Clinical Practice Guideline for Clinical Application of Biosimilars. Logistic regression model was employed to identify possible impact factors, and Spearman’s rank correlation test was used to identify the correlation between knowledge and attitudes. Chi-squared test was used to compare the differences between different stakeholders. Results: Overall, 599 valid respondents were recruited, of whom 77.63%, 7.01% and 15.36% were HCPs, healthcare regulatory practitioners and patients, respectively. A total of 504 respondents who had heard of biosimilars were included in the KAP analysis. 76.70% of HCPs, 90.24% of healthcare regulatory practitioners and 50.98% of patients had good knowledge about the definition, while less familiarity with the development process and regulations on interchangeability and indication extrapolation was found in the former two groups. For attitudes toward biosimilars, an overall lack of positivity was shown, as only 18.20% HCPs, 14.63% healthcare regulatory practitioners and 23.53% patients were classified as having positive attitudes. More specifically, most respondents were positive about the influence of payment policy on the uptake of biosimilars, but they showed a neutral attitude toward the clinical medication and interchangeability of biosimilars. Efficacy, safety, immunogenicity, interchangeability and indication extrapolation are major concerns when utilizing biosimilars. Regarding practice, our study showed an inadequate utilization of biosimilars in China. Several further suggestions on the regulation of biosimilars were proposed by healthcare regulatory practitioners. Conclusions: There is still plenty of room for improvement of knowledge, attitudes and practice toward biosimilars among multiple stakeholders in China, which can be improved through high-quality real world evidence, educational programs and other effective measures directed towards barriers.

Abstract
Background Beyond evaluation and approval, European and national regulators have a key role in providing reliable information on biosimilars and the science underpinning their development, approval, and use. Objectives This study aims to (i) review biosimilar information and guidance provided by EMA and national medicines agencies and (ii) explore stakeholder perspectives on the role of regulators in enabling acceptance and use of biosimilars. Methods This study consists of (i) a comparative review of regulatory information and position statements across medicine agencies (n = 32) and (ii) qualitative interviews with stakeholders in Europe (n = 14). Results The comparative analysis showed that regulatory information and guidance about biosimilars offered by national medicines agencies in Europe varies, and is limited or absent in multiple instances. Approximately 40% (13/31) of the national medicines agencies' websites did not offer any information regarding biosimilars, and for about half (15/31) no educational materials were provided. Only less than half of national medicines agencies provided guidance on biosimilar interchangeability and switching (8/31 and 12/31, respectively). Among the national medicines agencies that did offer guidance, the extent (e.g., elaborate position vs. brief statement) and content (e.g., full endorsement vs. more cautious) of the guidance differed substantially. Countries that have a strong involvement in EU level biosimilar regulatory activities generally had more elaborate information nationally. Interviewees underwrote the need for (national) regulators to intensify biosimilar stakeholder guidance, especially in terms of providing clear positions regarding biosimilar interchangeability and switching, which in turn can be disseminated by the relevant professional societies more locally. Conclusion This study revealed that, despite strong EU-level regulatory biosimilar guidance, guidance about biosimilars, and their use differs considerably across Member States. This heterogeneity, together with the absence of a clear EU-wide position on interchangeability, may instill uncertainty among stakeholders about the appropriate use of biosimilars in practice. Regulators should strive for a clear and common EU scientific position on biosimilar interchangeability to bridge this gap and unambiguously inform policy makers, healthcare professionals, and patients. Furthermore, there is a clear opportunity to expand information at the national level, and leverage EU-developed information materials more actively in this regard.

Abstract
As more biosimilars enter the pharmaceutical market, patient acceptance remains a significant barrier to their uptake. Psychological factors, such as negative expectations, are important causes of patient hesitancy. As a result, patients can develop nocebo responses following a transition, discontinue biosimilar treatment early, or have poor adherence. These negative outcomes may offset some of the cost-saving potential of biosimilars. Key healthcare professionals such as pharmacists, physicians, and nurses already play a noteworthy role in educating and transitioning patients. However, given the psychological aspect of biosimilar acceptance, it is logical for healthcare professionals and researchers to draw on research and theory from health psychology. This commentary outlines how a multidisciplinary approach can add to the understanding of the mechanisms behind patient resistance to biosimilars and help engage patients in the transitioning process. It also explores how health psychology strategies that have been successful in similar areas can be translated to help conduct more effective transitions. Future directions in research are discussed.

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.

Abstract
Patient perceptions influence biosimilar uptake in non-mandatory transitions. Companions (support people) are often actively involved in the patient's medical journey and are likely to have unique perceptions of biosimilars, which may shape patient attitudes. This study explores the congruence between patient and companion perceptions towards biosimilars and their information needs. Patients taking bio-originators for rheumatic diseases (59% for rheumatoid arthritis) and their companions received an explanation about biosimilars. Participants (N = 78) completed questionnaires assessing their familiarity with biosimilars, perceptions, concerns, and benefits of being accompanied. Contingency tables and paired sample t-tests were used to explore differences in familiarity, confidence in knowledge, and perceptions. Intra-class correlation coefficients were calculated to assess the degree of congruence for perceptions towards biosimilars. Companions were significantly less familiar with biosimilars (p = 0.014, Cramer's V = 0.28) and reported lower confidence in their knowledge (p = 0.006, Cohen's d = 0.47) than patients. Companions and patients had moderate to good congruency for perceptions toward confidence in biosimilar use and safety, efficacy, and side-effect expectations (intra-class correlation coefficients ranging from 0.75 to 0.81). Companions and patients were most concerned about safety and effectiveness. Companions also reported concerns about cost savings driving the transition, while patients had concerns about uncertainty and testing. Patients reported the ability for discussion, improved understanding, and validation as benefits of being accompanied. Companions and patients have similar levels of perceptions and expectations towards biosimilars but report some unique information needs. Future educational interventions should involve companions and address their concerns to help improve biosimilar acceptance.

Abstract
Background: Recent approvals for novel agents such as the small molecule Janus kinase
inhibitors (JAKi), combined with the advent of biosimilars has widened the
gamut of available therapeutic options in the treatment of rheumatoid
arthritis (RA). This combined with the introduction of mandatory non-
medical switches to biosimilars in some jurisdictions by both public and
private payors has led to a significant increase in the volume of
therapeutic changes for patients. Pharmacists are well positioned to ensure
effective and safe transitions, however there is a significant unmet need
for objective and subjective clinical guidance around therapy as well
disease state monitoring in RA that facilitates best practices throughout
the patient journey. Objective: In this paper we aim to create a consensus derived monitoring algorithm for
pharmacists to facilitate best practices throughout therapeutic transitions
from originator biologic to other originator biologics, biosimilars, and
Janus kinase inhibitors in RA. Methods: The Nominal Group Technique (NGT) was used to understand if consensus could
be found among the participants. Clinically relevant questions were
developed to capture solutions to the identified unmet need. The faculty
considered the questions as individuals, and privately generated
answers/ideas. After discussion and consideration, the participants ranked
the ideas and established a consensus. Results: Based on the outcome of the consensus discussions, an algorithm was created
to help guide pharmacists through therapeutic transitions in RA. The tool
covers important topics such as pre-transition considerations, avoiding the
nocebo effect for biosimilars, specific considerations for each drug or
class, monitoring efficacy, and when to refer. Conclusions: New classes of anti-rheumatic drugs including JAKi, along with the
introduction of biosimilars are presenting more opportunity for therapeutic
changes and monitoring in patients with RA. We hope our evidence-based
consensus derived guidance tool will assist frontline pharmacists in
supporting their patients to a successful therapeutic transition in RA.

Abstract
Effective patient-provider communication is crucial to promote shared decision-making. However, it is unclear how to explain treatment changes to ensure patient acceptance, such as when transitioning from a bio-originator to a biosimilar. This review investigates communication strategies used to educate patients on transitioning to biosimilars and explores whether the willingness to transition and treatment persistence differs for the delivery (verbal or written) and the amount of information provided. MEDLINE, Embase, Scopus, and relevant conference databases were systematically searched. Communication strategies from 33 studies (88% observational cohort studies) published from 2012 to 2020 were synthesized and willingness to transition, persistence, and subjective adverse events explored. Patients only received information verbally in 11 studies. The remaining 22 studies also provided written information. Cost-saving was the main reason provided for the transition. Patients were most willing to transition when receiving written and verbal information (χ2 = 5.83, p = .02) or written information that only addressed a few (3-5) concerns (χ2 = 16.08, p < .001). There was no significant difference for persistence or subjective adverse events (p's > .05). Few randomized controlled trials have been conducted. Available data shows more willingness to transition when patients received written and verbal information. Initial documents should contain basic information and consultations or telephone calls used to address concerns.

Abstract
BACKGROUND Involving patients in treatment decisions is commonplace in healthcare, and patients are frequently accompanied by a companion (support person). Companions are often actively involved in medical consultations, yet their impact on decisions to change medications is unknown. PURPOSE This study examines the influence of companions on a patient's decision to transition from their bio-originator therapy to a biosimilar. METHODS A parallel, two-arm randomized controlled trial was conducted with 79 patients taking a bio-originator for rheumatic diseases who regularly attend clinic with a companion. Patients were randomized to receive an explanation about a hypothetical transition to a biosimilar alone or with their companion. Patients reported willingness to transition, risk perceptions, difficulty understanding, social support, and completed the Decisional Conflict Scale and Satisfaction with Decision Scale. RESULTS Companions did not influence decisions to transition to biosimilars or cognitive and affective risk perceptions. Accompanied patients reported more difficulty understanding the explanation (p = .006, Cohen's d = .64) but thought it was more important to receive information with companions (p = .023, Cohen's d = -.52). Companions did not impact decision satisfaction or decisional conflict. Receiving emotional, but not practical support, was associated with less decisional conflict in accompanied patients (p = .038, r 2 = 0.20). CONCLUSIONS The presence of companions does not seem to influence risk perceptions or decisions about transitioning to biosimilars. Companions, however, impact the patient's reporting of their ability to understand treatment explanations. Providers should check understanding in all patients but may need to provide additional time or educational resources to accompanied patients and companions.

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.

Lobo F, Río-Álvarez I. Barriers to Biosimilar Prescribing Incentives in the Context of Clinical Governance in Spain. Pharmaceuticals (Basel) 2021; 14:ph14030283.

Abstract
Incentives contribute to the proper functioning of the broader contracts that regulate the relationships between health systems and professionals. Likewise, incentives are an important element of clinical governance understood as health services’ management at the micro-level, aimed at achieving better health outcomes for patients. In Spain, monetary and non-monetary incentives are sometimes used in the health services, but not as frequently as in other countries. There are already several examples in European countries of initiatives searching the promotion of biosimilars through different sorts of incentives, but not in Spain. Hence, this paper is aimed at identifying the barriers that incentives to prescribe biosimilars might encounter in Spain, with particular interest in incentives in the framework of clinical governance. Both questions are intertwined. Barriers are presented from two perspectives. Firstly, based on the nature of the barrier: (i) the payment system for health professionals, (ii) budget rigidity and excessive bureaucracy, (iii) little autonomy in the management of human resources (iv) lack of clinical integration, (v) absence of a legal framework for clinical governance, and (vi) other governance-related barriers. The second perspective is based on the stakeholders involved: (i) gaps in knowledge among physicians, (ii) misinformation and distrust among patients, (iii) trade unions opposition to productivity-related payments, (iv) lack of a clear position by professional associations, and (v) misalignment of the goals pursued by some healthcare professionals and the goals of the public system. Finally, the authors advance several recommendations to overcome these barriers at the national level.
