Effects of Message Framing on Patients' Perceptions and Willingness to Change to a Biosimilar in a Hypothetical Drug Switch

Students respond positively to an instructor collecting and sharing aggregated class demographic data from a survey in a high-enrollment physiology course

The impersonal nature of high-enrollment science courses makes it difficult to build student-instructor relationships, which can negatively impact student learning and engagement, especially for members of marginalized groups. In this study, we explored whether an instructor collecting and sharing aggregated student demographics could positively impact student-instructor relationships. We surveyed students in a high-enrollment physiology course about their perceptions of their instructor 1) distributing a demographic survey, and 2) sharing aggregated survey results in class. We found that 72% of students appreciated the demographic survey, and 91% thought it helped their instructor get to know them. Further, 73% of students expressed that the instructor sharing aggregated demographic data in class positively impacted their overall course experience, and over 90% thought both the collection and sharing of demographic data were appropriate. Most students felt both parts of the intervention increased their sense of belonging in class, increased how connected they felt to their instructor, and made their instructor seem more approachable and inclusive, although the intervention also made some students feel more different from their peers. Women and nonbinary students felt the demographic survey increased instructor approachability more than men, and liberal students felt the survey increased instructor approachability more than nonliberal students. Compared to men, women and nonbinary students were more likely to report that taking the survey increased instructor inclusivity and made them feel less different from their peers. Based on these results, collecting student demographic information and sharing it in aggregate may be a practical, effective way to enhance student-instructor relationships.NEW & NOTEWORTHY This study examined undergraduate student perceptions of a high-enrollment physiology instructor collecting student demographics and sharing aggregated results to promote course inclusion. Most students perceived the collection and sharing positively, with women and nonbinary students, as well as liberal students, perceiving greater benefits from the data collection than their counterparts. Our results indicate that collecting and sharing in aggregate student demographics may be an effective way to enhance student-instructor relationships in high-enrollment science courses.

An Educational Digital Tool to Improve the Implementation of Switching to a Biosimilar (Rapid Switch Trainer): Tool Development and Validation Study

Background

Switching to biosimilars is an effective and safe practice in treating inflammatory diseases; however, a nocebo effect may arise as a result of the way in which the switch is communicated to a given patient.

Objective

We aimed to design a gaming-based digital educational tool (including a discussion algorithm) to support the training of health care professionals in efficiently communicating the switch to biosimilars, minimizing the generation of a nocebo effect and thus serving as an implementation strategy for the recommended switch.

Methods

The tool was developed based on interviews and focus group discussions with key stakeholders, both patients and health care professionals. Messages likely to either generate trust or to trigger a nocebo effect were generated on the basis of the interviews and focus group discussions.

Results

A total 7 clinicians and 4 nurses specializing in rheumatology, gastroenterology, and dermatology, with balanced levels of responsibility and experience, as well as balance between geographic regions, participated in the structured direct interviews and provided a list of arguments they commonly used, or saw used, to justify the switching, and objections given by the patients they attended. Patients with immune-mediated inflammatory diseases who were taking biologic drugs with (n=4) and without (n=5) experience in switching attended the focus groups and interviews. Major topics of discussion were the reason for the change, the nature of biosimilars, and their quality, safety, efficacy, and cost. Based on these discussions, a list of objections and of potential arguments was produced. Patients and health care professionals rated the arguments for their potential to evoke trust or a nocebo effect. Two sets of arguments, related to savings and sustainability, showed discrepant ratings between patients and health care professionals. Objections and arguments were organized by categories and incorporated into the tool as algorithms. The educators then developed additional arguments (with inadequate answers) to complement the valid ones worked on in the focus groups. The tool was then developed as a collection of clinical situations or vignettes that appear randomly to the user, who then has to choose an argument to counteract the given objections. After each interaction, the tool provides feedback. The tool was further supported by accredited medical training on biosimilars and switching.

Conclusions

We have developed a digital training tool to improve communication on switching to biosimilars in the clinic and prevent a nocebo effect based on broad and in-depth experiences of patients and health care professionals. The validation of this implementation strategy is ongoing.

Barriers and Enablers Affecting the Uptake of Biosimilar Medicines Viewed Through the Lens of Actor Network Theory: A Systematic Review

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.

Communication skills-based training about medication switch encounters: pharmacy staff and patients' experiences

BACKGROUND

Non-medical medication switches can lead to difficult conversations. To support pharmacy staff, a communication training has been developed based on two strategies: 'positive message framing' to emphasize positive elements of the message and 'breaking bad news model' to break the news immediately and address emotions.

AIM

To assess how patients and trained pharmacy staff experience the application of communication strategies for non-medical medication switch conversations and which are barriers and facilitators for the application.

METHOD

The Kirkpatrick training evaluation model, level 3 'behavior', including barriers and facilitators and 4 'results' was used. Trained pharmacy staff registered switch conversation characteristics and asked patients to complete a questionnaire. Semi-structured interviews with trained pharmacy staff members were conducted. Quantitative data were analyzed descriptively and interview data were analyzed thematically.

RESULTS

Of the 39 trained pharmacy staff members, 21 registered characteristics of 71 conversations and 13 were interviewed; 31 patients completed questionnaires. Level 3: trained pharmacy staff self-reported they applied aspects of the strategies, though indicated this was not yet a standard process. Interviewees indicated signs of increased patient contact and job satisfaction. Time, face-to-face conversations and colleague support were facilitators. Level 4: pharmacy staff members were satisfied with most switch conversations (89%), particularly with addressing emotions (74%). Patients were (very) positive (77%) about the communication, particularly about clear explanations about the switch.

CONCLUSION

Pharmacy staff's learned behavior includes being able to apply aspects of the strategies. The training results show first signs of better patient-pharmacy staff relationships and increased job satisfaction.

Clinical outcomes and cost savings of a nonmedical switch to a biosimilar in children/young adults with inflammatory bowel disease

OBJECTIVES

The safety, efficacy, and cost savings associated with biosimilar medications are well established. However, a lack of pediatric data exists surrounding clinical outcomes when switching from an originator to a biosimilar. Our primary aim is to evaluate clinical outcomes following a nonmedical switch from the infliximab originator to a biosimilar in children and young adults with inflammatory bowel disease (IBD). Our secondary aim is to estimate cost savings associated with this switch.

METHODS

A quality improvement project was implemented to establish safe switching protocols, then those patients who underwent a nonmedical switch from the infliximab originator to the biosimilar were retrospectively reviewed. Demographic data, physician global assessments (PGAs), and laboratory values were recorded 1 year pre- and post-switch. Continuation rates on the biosimilar were reported at 6 and 12 months. Cost savings were estimated using two different pricing models.

RESULTS

Fifty-three patients underwent a nonmedical switch. Laboratory values including inflammatory markers, infliximab levels, and PGA scores remained similar when assessed pre- and post-switch. No infusion reactions or antidrug antibody development occurred. Two patients reported psoriasis-like rashes. Five patients switched back to the originator during the study period. There were 379 biosimilar infusions completed with an estimated total cost savings of $11,260 (average sales price) and $566,223 (wholesale acquisition cost).

CONCLUSIONS

Clinical remission rates, inflammatory laboratory markers, serious adverse events, infliximab levels, and antidrug antibodies remained similar after a one-time nonmedical switch to an infliximab biosimilar. Nonmedical switching to biosimilars resulted in significant cost savings.

Rheumatology Patients' Experiences of a Mandatory Nationwide Transition to an Adalimumab Biosimilar

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.

The Nocebo Effect

Adverse nocebo responses can cause harm to patients and interfere with treatment adherence and effects in both clinic practice and clinical trials. Nocebo responses refer to negative outcomes to active medical treatments in clinical trials or practice that cannot be explained by the treatment's pharmacologic effects. Negative expectancies and nocebo effects are less known than placebo responses. Nocebo effects can be triggered by verbal suggestions, prior negative experiences, observation of others experiencing negative outcomes, and other contextual and environmental factors. As research advances over the years, mechanistic knowledge is accumulating on the neurobiological mechanisms of nocebo effects. This review summarizes studies on different facets of nocebo effects and responses and discusses clinical implications, ethical considerations, and future directions.

Biosimilars: From Production to Patient

Biologic drugs are large, complex molecules produced through biotechnology. A biosimilar is a biologic product that is highly similar to an already approved biologic (reference product), with no clinically meaningful differences in purity, safety, or efficacy; as such, a biosimilar does not need to undergo the same level of study in a clinical trial program as the original reference product. Due to the potential impact of biosimilars on patient access and health care systems, the US Food and Drug Administration introduced an abbreviated pathway for approving biosimilars (351[k]) in 2009. There is strong evidence that switching from a reference product to a biosimilar does not reduce treatment effectiveness or increase the risk of adverse events. Biosimilars may reduce costs and increase patient access to biologic therapies. Biosimilar use in the United States has increased, as have the associated biosimilar cost savings, which are expected to reach $104 billion between 2020 and 2024. Yet, a need remains for increased knowledge among health care professionals and patients. Prescriber confidence is key to patient acceptance of biosimilars and minimizing the incidence of the nocebo effect. Infusion nurses are well positioned to help educate patients and to improve clinical outcomes across a range of diseases.

Patients' Perceptions of Biosimilars: A Systematic Review

OBJECTIVE

To systematically summarize and evaluate the findings of existing studies about patients' perceptions of biosimilars by assessing their attitudes and knowledge.

METHODS

We conducted a systematic review of published studies concerning patients' perceptions of biosimilars, using databases of China National Knowledge Infrastructure, SinoMed, Web of Science, PubMed, Embase, and Cochrane Library. Two independent reviewers screened a total of 2197 Chinese or English papers published between 1 January 2018, and 1 October 2022. We assessed the quality of the included studies by applying the Joanna Briggs Institute appraisal tools.

RESULTS

Forty-three studies were included in the review, with the majority originating from Europe (n = 22) and North America (n = 10). Of these studies, 37 were cross-sectional quantitative studies, three were quasi-experimental studies, and the remaining three were qualitative studies based on semi-structured interviews. The sample sizes of the included studies ranged from 9 to 6554 patients. Twenty-two out of 31 studies investigating patients' acceptance of biosimilars found that most participants expressed satisfaction with treatment using biosimilars. However, doubts about the clinical effects and regulatory approval pathway could negatively influence patients' attitudes. The majority of patients understood the economic advantages of biosimilars; however, some incorrectly connected lower prices with lower quality. Patients generally lacked knowledge about biosimilars. There were 6-51% of participants who were familiar with biosimilars, and 25-58% thought they did not know enough about biosimilars. Physicians, pharmacists, medicines agencies, academia, and patient associations were identified as the main sources of information on biosimilars for patients. Healthcare providers not informing or advising patients about switching may hinder patients from acquiring enough knowledge.

CONCLUSIONS

The majority of patients expressed satisfaction with treatment using biosimilars, but limited knowledge continued to impede their perceptions. Doubts about the clinical effects and regulatory approval pathway were identified as major factors that negatively influenced patients' attitudes towards biosimilars, while the impact of a price advantage was mixed. It is essential to maintain a focus on educating healthcare professionals about biosimilars, including their clinical outcomes and the regulatory pathway, which equips them to provide comprehensive and informed guidance to patients.

The impact of policy interventions to promote the uptake of biosimilar medicines in Belgium: a nationwide interrupted time series analysis

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.

Facilitating pharmacy staff's conversations about non-medical medication switches: Development and testing of a communication training

BACKGROUND

Non-medical medication switches, a change to another medicine or medication label not motivated by medical reasons, occur frequently. Switches often lead to negative patient emotions, such as confusion and anger. Pharmacy staff's communication, i.e. delivering the message and addressing patients' emotions is crucial, but experienced as difficult.

OBJECTIVE

To develop and test a communication training for the pharmacy team to facilitate medication switch conversations.

METHODS

A communication training was developed based on the 'breaking bad news model' and 'positive message framing' strategies, and incorporating needs and preferences from practice. The training consisted of an e-learning with theory and reflective exercises, a half-day live training session, and an online reflection session. The Kirkpatrick training evaluation model (levels one 'reaction' and two 'learning') was used to evaluate the training. Quantitative data were analyzed using descriptive statistics and interview data was transcribed verbatim and analyzed thematically.

RESULTS

Twelve pharmacists and 27 pharmacy technicians from 15 Dutch pharmacies participated in the training. According to Kirkpatrick's model level one, the major learning outcome was to give space to patients to express their emotions and/or concerns (e.g. more silences in the conversations). For level two, most participants valued practicing the conversations, role-playing, and receiving feedback. The majority of the participants indicated that they had sufficient tools and practice during the live training to apply the strategies in daily practice. A few participants still needed time and practice, or missed examples to apply the strategies.

CONCLUSION

The communication training based on the two strategies was well-received and participants felt well-equipped post-training. The take-away for participants was to give space to patients to express their emotions. Using these strategies and skills, pharmacy teams can tailor their medication counseling to patients' emotions and concerns during non-medical medication switches to better support patients in proper medication use.

Does an Information System Security Notice Format Influence Users’ Compliance Willingness from the Perspective of the Framing Effect?

Information security issues have triggered both academic and practical circles to think about operation management and the sustainable development of information systems. Based on the theory of framing effect, this study constructs a theoretical model of the presentation framework of security notice information on users’ compliance willingness and empirically tests the proposed research hypotheses using a combination of behavioral experiments and questionnaires to analyze the mechanism of the information presentation framework on compliance willingness. The results show that (1) the information presentation framework has a significant effect on users’ decision to comply, but it varies according to specific frameworks. While the attribute and risk frameworks have a significant effect on users’ decision to comply, the goal framework does not have a significant effect on users’ decision to comply. (2) The security notice situation moderates the relationship between the security notice information presentation frame and users’ compliance willingness, but this varies according to the specific situation of the specific framework. The security notice situation moderates the relationship between the attribute framework, the risk framework, and users’ compliance willingness but not the relationship between the goal framework and users’ compliance willingness. (3) Information security cognition has a moderating effect on the relationship between the security notice presentation framework and users’ compliance willingness, but it varies by the specific frameworks. Information security cognition moderates the relationship between attribute frames, risk frames, and users’ compliance willingness but not the relationship between goal frames and users’ compliance willingness.

Using family-centered communication to optimize patient-provider-companion encounters about changing to biosimilars: A randomized controlled trial

OBJECTIVE

To explore whether family-centered communication impacts decisions and optimizes patient-companion-provider consultations.

METHODS

A parallel, two-arm randomized controlled trial was conducted with 108 participants acting as patients with inflammatory arthritis or companions. Pairs attended a mock consultation where a physician explained the change from a bio-originator to a biosimilar using family-centered or patient-only communication. Participants reported their willingness to transition, risk perceptions, understanding and social support, and completed various scales including the Patient Perception Scale. Interviews helped understand perceptions towards the consultation.

RESULTS

Family-centered communication did not impact willingness to change or cognitive risk perceptions compared to patient-only communication. However, it improved emotional risk perceptions (p = 0.047, Cohen's d=.55) and satisfaction with communication (p = 0.015, Cohen's d=.71). Feeling the explanation was reassuring was associated with less worry (p = 0.004). Receiving emotional support (p = 0.014) and companions asking fewer questions (p = 0.046) were associated with higher recall. The intervention improved companion involvement (p < 0.001, Cohen's d= 1.23) and support (p = 0.002, Cohen's d=.86). Interviews showed that encouraging questions, inclusive body language, and acknowledging companions facilitated involvement.

CONCLUSION

Family-centered communication augments patient-companion-provider encounters but does not influence willingness to change treatment.

PRACTICE IMPLICATIONS

Practitioners can use family-centered communication when discussing biosimilars but should provide reassurance, encourage emotional support, and summarize key points to improve understanding.

Perceptions towards biologic and biosimilar therapy of patients with rheumatic and gastroenterological conditions

BACKGROUND

Biologic and targeted synthetic disease modifying agents (b/tsDMARDs) have broadened the treatment landscape for autoimmune diseases particularly in patients refractory to conventional DMARDs. More recently, the introduction of biosimilars has reduced the price of bDMARDs, potentially improving accessibility. Though efficacy and safety have been described, patient attitudes to b/tsDMARDs are not well-understood. We aim to investigate patients' beliefs about biologic and biosimilar therapy, and the factors influencing their perceptions.

METHODS

Patient consumer groups (Arthritis Australia, Crohn's and Colitis Australia) assisted in advertising an online questionnaire for people with a self-reported diagnosis of inflammatory arthritis (IA) or inflammatory bowel disease (IBD). The questionnaire incorporated the Belief about Medicines Questionnaire (BMQ) and the single-item literacy screener (SILS). Sources and favourability of biologic/biosimilar information were analysed, using the chi-square and a non-parametric trend test for unordered and ordered categorical variables respectively, comparing respondents with IA and IBD.

RESULTS

Eight hundred and thirty eight people (686-IA, 144-IBD, 8 both) responded. 658 (79%) used b/tsDMARDs. The BMQ demonstrated high necessity belief (median 4.2) with moderate concerns (median 2.8) about biologics. 95% of respondents obtained medication information from specialists though most used multiple sources (median 4). The most positive resources were specialists and specialist nurses. 73/141 (52%) respondents with IBD obtained information from specialist nurses compared with 202/685 (29%) with IA (p = 0.012). Respondents with limited reading ability on SILS were more likely to discuss information with a general practitioner or pharmacist. Younger respondents and those with higher BMQ concern scores more frequently consulted less reliable sources (e.g. social media). 502 respondents (60%) answered the biosimilar questions. Only 23 (4.6%) reported currently using a biosimilar and 336 (66.9%) were unsure if biosimilars were available in Australia. Specialist recommendation was the most frequent factor that would influence a patient to change from originator to biosimilar (352/495, 71.1%).

CONCLUSIONS

There is a high level of trust in specialists' recommendations about b/tsDMARDs, although most people also utilise additional information sources. Contextual factors influencing resource selection include age, reading ability and degree of concern about medicines. People with IA and IBD have similar attitudes though those with IBD more frequently access specialist nurse advice.

Applications of Behavioral Economics to Pharmaceutical Policymaking: A Scoping Review with Implications for Best-Value Biological Medicines

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.

Effectiveness and safety of a biosimilar-to-biosimilar switch of the TNF inhibitor etanercept in patients with chronic inflammatory rheumatic diseases

Background:

Biosimilar disease-modifying anti-rheumatic drugs (bsDMARDs) has created a financial incentive to encourage switching to cheaper products.

Objectives:

We aim to study the effectiveness and safety of a non-medical bsDMARD-to-bsDMARD switch from originator etanercept (ETN) to bsDMARD ETN (SB4) and successive to another bsDMARD ETN (GP2015) in patients with chronic inflammatory rheumatic diseases in a real-life setting.

Methods:

Retrospective chart review of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) who had been treated with originator ETN and were switched twice to ETN bsDMARD for non-medical reasons thereafter. All patients received ETN 50 mg/week. Disease activity and physical function was assessed every 12 weeks with standardized questionnaires.

Results:

A total of 100 patients who switched twice [54 RA, 27 axSpA, 19 PsA, mean age 54.3 (15.1), 46% male] were included. Patients with axSpA were younger than RA and PsA patients. Patients with SpA were less likely to receive conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) than RA patients. Duration of treatment with originator ETN before the first switch was 3.3 (2.3) years. Retention rate 6 months after the second ETN bsDMARD switch was 89%. Disease activity and physical function scores remained rather unchanged in patients with RA and axSpA longitudinally, while there was some more fluctuation in PsA patients. Six patients lost efficacy and were switched back to originator ETN in month 6 (n = 4) or to another mode of action (n = 2). There were 14 adverse events (AE) reported in eight patients. One patient re-administered bsDMARD GP2015 successfully 3 months after healing of mucosal erosions.

Conclusion:

No relevant change in disease activity and physical function were observed in a non-medical bsDMARD-to-bsDMARD switch scenario. The retention rate after switches from originator ETN to two ETN bsDMARD was close to 90%. Multiple switches resulted in a high adherence rate without clinically important efficacy or safety signals.

Patient and Caregivers' Perspectives on Biosimilar Use in Pediatric Inflammatory Bowel Disease

BACKGROUND

Studies assessing adult inflammatory bowel disease (IBD) patient perspectives on biosimilar use revealed that most were unfamiliar with biosimilars and had a negative perception. The objective of this study was to evaluate the perspectives of pediatric patients with IBD and their caregivers regarding biosimilar use and non-medical switches.

METHODS

A survey was given to a cross section of patients with IBD ages 11-21 years receiving the intravenous anti-tumor necrosis factor originator and caregivers of patients with IBD ages 3-21 years receiving the originator. Recruitment occurred via mail, during clinic visits, and infusions. Fisher exact tests were used to test for statistically significant differences.

RESULTS

Response rate amongst caregivers was 49% (n = 98) and among patients was 35% (n = 67). Sixty-four percent of caregivers and 79% of patients had never heard of biosimilars. There was increased discomfort surrounding the use of biosimilars and switching to a biosimilar amongst caregivers who had previously heard of biosimilars compared to caregivers who had not previously heard of biosimilars ( P < 0.05). Similar concerns were not seen in patient respondents. The length of time on the originator had no effect on patient or caregiver concerns related to biosimilar efficacy, adverse effects, or switches.

CONCLUSION

The majority of pediatric patients and caregivers had never heard of biosimilars. Caregivers that had heard of biosimilars before the study were more likely to have a negative perception of them. This study highlights the importance of providing thorough and accurate education to pediatric patients and families regarding the safety and efficacy of biosimilars.

Exploring the Reasons Behind the Substantial Discontinuation Rate Among Patients Taking CT-P13 in a Large Tertiary Hospital in Western Switzerland: A Retrospective Cohort Study Using Routinely Collected Medical Data

BACKGROUND

CT-P13 is an infliximab biosimilar that was granted market authorization in Switzerland in 2016. Despite the growing literature supporting the equivalence of CT-P13 compared with originator infliximab regarding the efficacy, safety, and immunogenicity and the undeniable cost-saving opportunities, CT-P13 remains widely underused in Switzerland.

OBJECTIVE

Leaving aside the phenomenon of a low initiation rate, this study aimed to explore the reasons behind the high discontinuation rate observed among the patients taking CT-P13 in a large tertiary hospital in Western Switzerland.

METHODS

We performed a retrospective cohort study using routinely collected data. Patients were eligible if they received originator infliximab or CT-P13 between September 2017 and December 2020. They were included if they had received at least two CT-P13 infusions during the same period. Patients were excluded if the follow-up was incomplete prior to or 6 months after their first CT-P13 infusion and if they had an oncological main diagnosis. Primary outcomes were the reasons for treatment discontinuation.

RESULTS

One hundred and fifty-six patients were included and classified into two groups: switchers who were treated with originator infliximab and were switched to CT-P13 (n = 85, 54%) and initiators who did not receive originator infliximab prior to CT-P13 treatment (n = 71, 46%). Included patients belonged to three different groups of diagnosis: gastroenterological (67, 43%), rheumatological (61, 39%), and immunological (28, 18%). Twenty-three (27%) switchers and 35 (49%) initiators discontinued CT-P13 after 12 months. Main reasons for CT-P13 discontinuation were lack of efficacy (n = 21, 36%) and secondary loss of response (n = 16, 28%); however, objective assessments were not available. Initiators' probability to discontinue CT-P13 at 12 months was significantly higher than switchers' (p < 0.01).

CONCLUSIONS

Lack of efficacy and secondary loss of response were the main reasons for the high CT-P13 discontinuation rate observed in a large tertiary hospital in Western Switzerland. Lack of active training and coordination among healthcare professionals and little education in patients may have exacerbated patients' subjective complaints and increased the CT-P13 discontinuation rate.

Moving forward: Implementing health psychology research to improve patient acceptance of biosimilars

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.

[Use of biosimilars in the treatment of rheumatoid arthritis : An overview]

Biologics have been an integral part of the treatment of rheumatoid arthritis for approximately 20 years. As patents for pharmaceuticals generally expire after 10 years, in recent years biosimilars have come onto the market. Many studies have shown that they are an equivalent alternative to the reference drug with comparable safety and efficacy. In some cases, they even showed lower rates of adverse drug reactions compared to the reference drugs. Furthermore, considerable costs can be saved by biosimilars, which amount to an annual three-digit million sum in Germany alone. Large regional differences in the prescription frequency of biosimilars in Germany can be identified, which are also reflected in the savings potential. A switch to a biosimilar is possible and desirable with the involvement of the patient. In this sense, the initial prescription of a biosimilar instead of the reference drug is also to be advocated.

Incidence of and Reasons and Determinants Associated with Retransitioning from Biosimilar Etanercept to Originator Etanercept

Background

Patients in clinical practice are transitioned from originator etanercept (OR-ETA) to biosimilar etanercept (BS-ETA), but some subsequently retransition. Insights into the incidence of and reasons for retransitioning and the characteristics of these patients could help clinicians successfully introduce biosimilars.

Objective

Our objective was to assess the incidence of and reasons for retransitioning from BS-ETA to OR-ETA in patients with a rheumatic disease (RD) and to explore the determinants thereof.

Methods

This cohort study included all patients with RD who had transitioned from OR-ETA to BS-ETA in a large hospital in the Netherlands in 2016. The incidence of retransitioning to OR-ETA and the 1-year persistence with BS-ETA were assessed using the Kaplan–Meier estimator. Reasons for retransitioning were classified as related to (1) efficacy, (2) adverse events, (3) the administration device, and (4) other. Determinants for retransitioning, including baseline and treatment characteristics, were assessed in a nested case–control study using conditional logistic regression.

Results

We included 342 patients (median age 57.8 years; 53.5% females). At 1 year after transitioning, 9.4% of patients had retransitioned to OR-ETA and 69.7% were persistent with BS-ETA. At the end of follow-up (median 4.4 years), 47 patients (13.7%) had retransitioned to OR-ETA. The median time until retransitioning was 0.55 years (interquartile range 0.2–1.3). Most patients (n = 34 [72.3%]) retransitioned because of a (perceived) loss of effect, followed by adverse events (23.4%). In total 3.8% of patients switched to another biological treatment or a Janus kinase inhibitor; 17.1% of patients discontinued BS-ETA without retransitioning or switching within the first year. Univariate determinants for retransitioning included initiating corticosteroids or intensifying immunomodulator treatment (odds ratio [OR] 2.37; 95% confidence interval [CI] 1.03–5.45) and the number of visits to the rheumatology department (OR 2.06; 95% CI 1.55–2.74). In the multivariate analysis, only the number of visits to the rheumatology department remained significantly associated with retransitioning (OR 2.19; 95% CI 1.60–3.01).

Conclusion

When introducing a biosimilar in clinical care, clinicians should anticipate that one in seven patients will retransition to the originator. A (perceived) loss of effect was the most frequently reported reason for retransitioning. Patients who visited the rheumatology department more frequently had an increased risk of retransitioning, which is likely to be related to patients reporting a loss of effect and to adverse events resulting in more visits to the rheumatology department.

A bio-what? Medical companions' perceptions towards biosimilars and information needs in rheumatology

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.

Treatment journey in rheumatoid arthritis with biosimilars: from better access to good disease control through cost savings and prevention of nocebo effects

Early diagnosis and treatment of rheumatoid arthritis (RA) are of critical importance to halt the progression of the disease. Optimal use of advanced imaging techniques or biomarkers may facilitate early diagnosis of RA. Even though many disease-modifying anti-rheumatic drugs (DMARDs) are available for RA treatment, biological DMARDs (bDMARDs) offer expanding therapeutic options and good outcomes in patients with RA who do not have a sufficient response to conventional synthetic DMARDs. However, high costs of bDMARDs have limited patient access to optimised disease management and increased the cost burden for healthcare systems. The advent of biosimilars led to significant cost savings driven by price competition among the reference products, which could be beneficial for healthcare systems. Healthcare provider (HCP)–patient communication and informed shared decision-making are crucial to prevent the occurrence of a nocebo effect, which results from negative perceptions that patients may have and could lead to less effective outcomes. Research has demonstrated that effective communication between HCPs and patients utilising positive framing can improve acceptance by patients to be initiated on or switched to a biosimilar and can help to integrate biosimilars into routine clinical practice to maximise benefits for patients with RA.

The mode of delivery and content of communication strategies used in mandatory and non-mandatory biosimilar transitions: a systematic review with meta-analysis

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.

Is Three a Crowd? The Influence of Companions on a Patient's Decision to Transition to a Biosimilar

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.

Biosimilar Uptake: The Importance of Healthcare Provider Education

From peptide hormones to monoclonal antibodies, advances in biotherapeutic medicines, or biologics, have brought incalculable benefits to patients, especially for conditions where previous classes of therapy were ineffective or non-existent. At the same time, the development of biologics has been accompanied by questions of access and cost. The advent of biosimilars, molecules highly similar to their reference biologics, has offered the promise of ameliorating cost and access challenges. However, issues regarding biosimilar uptake remain. Multiple factors impact the utilization of biosimilars by healthcare providers and perhaps the best recognized of these is education. This paper discusses the importance of education to biosimilar adoption and lists action-items that various stakeholders in healthcare can adopt to improve the overall understanding of this important class of therapeutics.

Policies to Encourage the Use of Biosimilars in European Countries and Their Potential Impact on Pharmaceutical Expenditure

Introduction: Biosimilar medicines are considered promising alternatives to new biologicals with high price tags. The extent of savings resulting from biosimilar use depends on their price and uptake, which are largely shaped by pricing, reimbursement, and demand-side policies. This article informs about different policy measures employed by European countries to design the biologicals market and explores potential savings from the increased use of biosimilar medicines in Germany. Methods: Policy measures that target the price and uptake of biosimilar medicines were identified based on a prefilled questionnaire survey with public authorities in 16 European countries, who were the members of the Pharmaceutical Pricing and Reimbursement Information network (July 2020). Potential savings that could have been generated in Germany if different measures identified in the surveyed countries had been implemented were calculated for six publicly funded biological molecules. Price data of the Pharma Price Information service and German consumption data for 2018 were used for the calculation of five scenarios. Results: Several countries use a price link policy, setting the biosimilar price as a percentage of the price of the reference biological. Also lowering the price of the reference biological upon market entry of a biosimilar is less frequently used. While tendering of biosimilar medicines in the inpatient setting is the norm, it is rarely employed for biosimilars in outpatient use. Reference price systems and INN prescribing of medicines are the commonly used policy measures in the off-patent market, but some countries define exemptions for biologicals. Substituting biosimilars at the pharmacy level is rather an exception. Potential savings in Germany ranged from 5% (simple price link) to 55% (prices at the level of other countries) for the six studied molecules. Conclusion: Despite some differences, there are discernible tendencies across European countries with regard to their applications of certain policy measures targeting the price and uptake of biosimilar medicines. The potential for savings of some of these policies was clearly demonstrated. Monitoring and evaluation of these rather recent measures is key for obtaining a more comprehensive picture of their impact.

Who is afraid of biosimilars? Openness to biosimilars in an Australian cohort of patients with rheumatoid arthritis

Biosimilars are increasingly adopted to improve affordability of biologics. An effective introduction of biosimilars requires an understanding of patient acceptance of these agents. We performed a cross-sectional study of 132 patients with rheumatoid arthritis prior to the introduction of biosimilar switching or prescribing in this cohort. Despite being unfamiliar with biosimilars, most patients are willing to accept biosimilar medicines if recommended by their rheumatologist. Patient concerns about biosimilar uptake mainly focus on concerns about its efficacy. There is a significant correlation between patient attitudes towards biosimilar and generic medicines.

Informing Patients about Biosimilar Medicines: The Role of European Patient Associations

Biosimilar medicines support the sustainability of national healthcare systems, by reducing costs of biological therapies through increased competition. However, their adoption into clinical practice largely depends on the acceptance of healthcare providers and patients. Patients are different from health care professionals (HCPs), who are informing themselves professionally. For patients, the biosimilar debate only becomes actual when they are confronted with disease and drug choices. This paper provides a literature review on how patients are and should be informed about biosimilars, searching in scientific databases (i.e., Medline, Embase). Several large surveys have shown a lack of knowledge and trust in biosimilars among European patients in recent years. This review identified five main strategies to inform patients about biosimilars: (1) provide understandable information, (2) in a positive and transparent way, (3) tailored to the individual’s needs, (4) with one voice, and (5) supported by audiovisual material. Moreover, the importance of a multistakeholder approach was underlined by describing the role of each stakeholder. Patients are a large and diffuse target group to be reached by educational programs. Therefore, patient associations have become increasingly important in correctly informing patients about biosimilar medicines. This has led to widespread biosimilar information for patients among European patient associations. Therefore, a web-based screening of European Patients’ Forum (EPF) and International Alliance of Patients’ Organizations (IAPO) member organizations on publicly available information about biosimilars was performed. We found that the level of detail, correctness, and the tone of the provided information varied. In conclusion, it is paramount to set up a close collaboration between all stakeholders to communicate, develop, and disseminate factual information about biosimilars for patients.

Biosimilar-Umstellung: Gesprächstechnik beeinflusst Bereitschaft der Patienten

Viele Patienten mit rheumatischen Erkrankungen stehen der Umstellung von einem Biologikum auf ein Biosimilar kritisch gegenüber und viele behandelnde Ärzte sind unsicher, wie sie die Akzeptanz der Betroffenen erhöhen können. Ein Team neuseeländischer Forscher hat nun untersucht, welche Gesprächstechniken bei den Patienten eine positive Einstellung gegenüber dem Präparatewechsel hervorrufen.

The Importance of Countering Biosimilar Disparagement and Misinformation

Biosimilar use is limited in some healthcare systems because biosimilars are not well understood by many healthcare professionals and patients. The knowledge gap is exacerbated by disparagement of biosimilars and dissemination of misinformation, whether intentional or otherwise. There are several different types of disparagement and misinformation directed towards biosimilars as a class, including statements about biosimilar science or policy that are factually incorrect; misleading information, where the information is correct, but is provided out of context; incomplete information, where only partial or a limited set of facts are provided; creation of a false narrative, especially in scientific and medical literature, that provides a set of references to support incorrect conclusions; and negative message framing of factual statements to create a negative perception. Disparagement and misinformation about biosimilars can be countered by educational efforts, appropriate oversight, and regulatory activities with the option of enforcement action by governmental agencies, if warranted. Balanced educational materials about biosimilars should be made easily accessible. Physicians, nurses, pharmacists, and patient advocacy groups should work together to provide patients with consistent, positive messages about the value of biosimilars.

Patients' beliefs and behaviours are associated with perceptions of safety and concerns in a hypothetical biosimilar switch

Although patient acceptance is important for biosimilar adoption and reducing healthcare costs, many patients perceive biosimilars to be unsafe and have concerns about switching. Studies show that patients' characteristics influence negative perceptions toward generic drugs, but little research has explored biosimilar acceptance. This study examines which demographic and psychological characteristics are associated with patients' safety perceptions and concerns about switching to biosimilars. Ninety-six patients taking bio-originators for rheumatic conditions (65% for rheumatoid arthritis) completed the Brief Illness Perceptions Questionnaire, Beliefs about Medicines Questionnaire and Perceived Sensitivity to Medicines Scale. Demographic factors, information seeking, concerns about switching and safety perceptions were also assessed. Pearson's correlations and hierarchical linear regressions were conducted to explore whether patient characteristics are associated with perceptions of biosimilars. Negative safety perceptions were associated with being female, short-term bio-originator use, illness beliefs, seeking health information online, high perceived sensitivity to medicines and negative beliefs about medicines. Only being female (β = 0.24, P = 0.02) was independently associated. More concerns about switching were associated with being female, illness beliefs, high perceived sensitivity to medicines, information-seeking behaviours and preferring innovator drugs. Seeking health information online (β = 0.20, P = 0.04), preferring innovator drugs (β = 0.29, P = 0.004) and stronger emotional responses (β = 0.26, P = 0.01) were independently associated. Perceived bio-originator effectiveness was inversely associated with preferring biosimilars (r_s=  - 0.33, P < 0.001). Patients who have stronger emotional responses to their condition, are females, seek health information online and prefer innovator drugs that have more negative perceptions about biosimilars. Experiences with bio-originators influence attitudes towards switching.

[Biosimilars and the nocebo effect]

Biosimilars have been approved for use in Germany for many years and in the meantime also in rheumatology but only a few years ago. Biosimilars, which are biotechnologically manufactured products the same as reference biologicals, have actually now achieved a substantial proportion of the market in some regions but there are still doubters among patients and physicians who fear a loss of quality even if there is no evidence for this. A part of this problem can be explained by the nocebo effect but which furthermore also has a substantial medical importance. This effect is described and explained in this article. Psychosocial and context-related factors, such as the relationship between patient and physician, previous experience with treatment and treatment expectations can either improve or impair the efficacy of treatment interventions. These phenomena are commonly known as placebo and nocebo effects. As placebo and nocebo effects can influence the development of symptoms, the frequency of undesired events and the efficacy of treatment, it is decisive to know these effects and to develop strategies for prevention in order to optimize the treatment results. Although in recent years experimental studies have achieved substantial progress in the clarification of the psychosocial and neurobiological mechanisms of placebo effects, detailed mechanisms of nocebo effects are still widely unexplored. An improved understanding of these mechanisms promises the development of user-friendly strategies for the clinical care to improve treatment results and patient satisfaction.
