Abstract
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.

Abstract
OBJECTIVES Transition from originator biological medicines to their biosimilar equivalents is now part of routine clinical practice, but there is little understanding of patient experiences, which influence adherence and overall satisfaction with care. Understanding this will help ensure future switches adequately address patients' concerns and expectations leading to better outcomes for all stakeholders. METHOD 35 patients participating in a clinical trial including an open-label transition event from originator to biosimilar adalimumab, mimicking what would be encountered in a real-world setting, took part in semi-structured interviews exploring their experience of biosimilar transition. RESULTS Opinions expressed were often heterogeneous, but common experiences and themes were identified. Five themes were identified following thematic analysis. (1) Understanding and awareness of biosimilars: prior awareness of biosimilars and knowledge of the biosimilar concept was low, indicating a disparity between healthcare professionals and patients. (2) Motivation to undertake transition: patients accept a biosimilar transition to minimise drug expenditure. (3) Initial concerns: before undertaking biosimilar transition away from the brand they had experienced, anticipated loss of efficacy and adverse effects from the biosimilar were common concerns for patients. (4) Reassuring factors: trust in the healthcare team is critical to patient acceptance of biosimilars. Important reassurances include a point of contact, education about biosimilars and monitoring. (5) Experiences during the transition: on reflection, participants described consistent efficacy and tolerability (although 22 participants specifically mentioned injection pain) following brand transition. CONCLUSION The majority of patients felt comfortable with future transition to another adalimumab biosimilar. Injection experience was an important component of patient satisfaction.

Abstract
BACKGROUND AND AIM There are few clinical data on Adalimumab (ADA) biosimilars in inflammatory bowel disease. We aimed to perform a multicenter, observational, prospective study on safety and effectiveness of ADA biosimilar ABP 501 in patients with inflammatory bowel disease. METHODS All consecutive patients from the cohort of the Sicilian Network for Inflammatory Bowel Disease treated with ADA biosimilar ABP 501 from February 2019 to February 2020 were enrolled. Patients were divided into three groups: group A, naïve to ADA and naïve to anti-tumor necrosis factors; group B, naïve to ADA and previously exposed to anti-tumor necrosis factors; and group C: switched from ADA originator to ABP 501. RESULTS A total of 559 patients (median age 39 years; Crohn's disease 88.0%, ulcerative colitis 12.0%) were included, with a follow-up time of 403.4 patient-years. Thirty-six serious adverse events occurred in 36 patients (6.4%; incidence rate [IR]: 8.9 per 100 person-years [PY]). The IR of serious adverse events was higher among patients in group A compared with group C (17.4 vs 4.8 per 100 PY; IR ratio = 3.61; P < 0.001) and among patients in group B compared with group C (16.4 vs 4.8 per 100 PY; IR ratio = 3.42; P = 0.041). Among ADA-naïve patients (group A + B), 188 (85.8%) had a clinical response after 12 weeks, including 165 (75.3%) who achieved steroid-free remission. Higher treatment persistence estimates were reported for patients in group C compared with groups A and B (log-rank P < 0.001). CONCLUSIONS Safety and effectiveness of ABP 501 seem to be overall similar to those reported for ADA originator. Switching from originator to ABP 501 was safe and effective.

Abstract
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.

Abstract
Background: There are gaps in gastroenterologist team members' understanding of various topics related to biosimilars. We aimed to examine perspectives, views, and attitudes toward biosimilar and shared decision-making (SDM) among gastroenterology team members in Colorado, USA. The ultimate goal was to increase knowledge and awareness of biosimilars and SDM. Research design and methods: We developed educational materials focused on biosimilars and SDM and distributed them to each participating gastroenterology office. Subsequently, we conducted a survey of all team members from participating offices. Results: Responses were obtained from 54 gastroenterology team members. Most respondents identified the correct answer regarding biosimilars, the nocebo effect, and SDM. Almost half (47.2%) of respondents scored their level of awareness regarding biosimilars prior to reading our educational materials as poor, and nearly one quarter (26.4%) indicated so for SDM. Improvement in scores after reading our materials was significant for both biosimilars and SDM (i.e. biosimilar: z = 6.276, p-value <0.001 and SDM z = 6.328, p-value <0.001). Conclusions: Educational efforts effectively increased the low baseline knowledge and awareness of biosimilars and SDM among gastroenterology team members. More educational projects focused on biosimilars and SDM are needed to reduce the nocebo effect and prevent hampering of the cost-savings of biosimilars.
