Abstract
INTRODUCTION Disease-modifying anti-rheumatic drugs (DMARDs) have improved the outcomes of patients with rheumatoid arthritis (RA). DMARDs are classified into three categories: conventional synthetic DMARDs, biological DMARDs (including biosimilars), and targeted synthetic DMARDs. DMARDs, by way of their effect on the immune system, are associated with increased risk of adverse events, including infections, malignancies, cardiovascular disease, gastrointestinal perforations, and other less common events. AREAS COVERED In this narrative literature review performed with searches of the PubMed database from 1 January 2010 through 1 January 2023, we compare the risk of safety events between DMARDs using data from both randomized clinical trials and observational studies. EXPERT OPINION DMARD use in RA is associated with higher rates of serious infections, tuberculosis reactivation, opportunistic infections, and possibly malignancies. Specific biologic DMARDs and higher doses are associated with elevated risks of various adverse events (gastrointestinal perforations, thromboembolism, serious infection). Shared decision-making is paramount when choosing a treatment regimen for patients based on their own comorbidities. JAKi are the newest class of medications used for RA with robust safety data provided in clinical trials. However, more real-world evidence and phase-IV pharmacovigilance data are needed to better understand comparative safety profile of DMARDs in RA.

Characteristics and 6-Month Outcomes in Patients with Rheumatoid Arthritis Initiating Infliximab Biosimilar IFX-dyyb in a Real-World Setting. Rheumatol Ther 2024; 11:841-853. [PMID: 38507187 PMCID: PMC11111629 DOI: 10.1007/s40744-024-00653-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 02/07/2024] [Indexed: 03/22/2024] Open
Abstract
INTRODUCTION Real-world studies describing biosimilar initiation or switching in patients with rheumatoid arthritis (RA) are limited. The aim of this study was to assess treatment patterns and effectiveness of real-world patients with RA initiating infliximab biosimilar IFX-dyyb (CT-P13; Inflectra®) in the USA. METHODS This observational study evaluated patients with RA from the CorEvitas RA Registry who initiated IFX-dyyb and had Clinical Disease Activity Index (CDAI) recorded at baseline and 6 months. The primary outcome was reaching low disease activity (LDA; CDAI ≤ 10) at 6 months in patients with moderate or high disease activity (CDAI > 10) at baseline. Secondary outcomes were change at 6 months in CDAI and certain patient-reported outcomes (PROs). Patient data were stratified by prior treatment: biologic/targeted synthetic disease-modifying antirheumatic drug (tsDMARD)-naïve, reference infliximab (IFX-REF) or IFX biosimilar, or a non-IFX biologic or tsDMARD. RESULTS Of 318 patients initiating IFX-dyyb, 176 had baseline and 6-month CDAI scores; 73 (41%) switched from IFX, 61 (35%) switched from another non-IFX/biologic/tsDMARD, 32 (18%) were naïve to biologics/tsDMARDs, and 10 (6%) switched from an IFX biosimilar. Among patients with moderate or high disease activity at baseline, 32.9% (95% CI 22.9, 42.9) achieved LDA at 6 months. Mean 6-month change from baseline in CDAI was - 1.8 (95% CI - 3.3, - 0.3) overall; - 4.7 (- 7.6, - 1.7) in patients who switched from a non-IFX biologic/tsDMARD, - 4.1 (- 7.8, - 0.3) in biologic/tsDMARD-naïve patients, and 1.1 (- 0.4, 2.6) in patients who switched from IFX-REF/IFX biosimilar. Other clinical outcomes/PROs improved at 6 months. Of the IFX-dyyb initiators, 68% remained on IFX-dyyb at 6 months. CONCLUSION In this real-world population of patients with RA initiating IFX-dyyb, the majority switched from IFX-REF or a non-IFX biologic/tsDMARD. CDAI remained stable in patients switching from IFX-REF/IFX biosimilar and improved in patients switching from a non-IFX biologic/tsDMARD and in biologic/tsDMARD-naïve patients.

Abstract
BACKGROUND: Infliximab (IFX) was one of the first tumor necrosis factor inhibitors developed to treat rheumatoid arthritis (RA) and has transformed the treatment and management of many chronic inflammatory diseases. Large-scale studies in the real-world setting on the utilization patterns of IFX biosimilars are limited. OBJECTIVE: To conduct a scoping review of observational studies investigating the switching and discontinuation outcomes of the IFX biosimilars in patients with RA. METHODS: A comprehensive literature search was conducted in 3 databases (ie, PubMed, Embase, and Web of Science). This review identified observational studies that examined switching and/or discontinuation outcomes of IFX biosimilar products in adult patients with RA. Studies published in English between 2015 and 2020 were included. Studies that did not include either switching or discontinuation patterns of IFX biosimilars, had a pooled result for biologics, or were nonobservational were excluded. Extracted data were summarized using descriptive statistics. RESULTS: The initial literature search yielded 1,130 studies. With 244 duplicate articles removed and 779 excluded after title and abstract screening, the search resulted in 107 studies for full-text screening. 18 articles were included in this review. 13 countries were represented in the included studies, with most studies originating in a European country and only one article from the United States. Discontinuation rates of IFX biosimilars were reported by 14 studies and varied substantially from 8.3% to 87.0%. 4 studies (22%) directly compared discontinuation rates between IFX reference and biosimilar. Switching rates, similarly, had a great variance from 4% to 81.5%; only 4 articles described rates specifically in patients with RA. The most common causes of discontinuation were ineffectiveness and adverse effects. CONCLUSIONS: The growing market of biologic products necessitates more large-scale studies examining the real-world treatment patterns of these therapy options to provide reassurance to and build trust among patients and clinicians. Our findings suggest the inconclusiveness of current literature on the real-world implications of IFX biosimilars discontinuation and product switching. This review captures the heterogeneity in reported data and identifies areas for future research to provide clarity to the value of IFX biosimilars.

Abstract
Ankylosing spondylitis is a chronic inflammatory disorder characterized by inflammation of the axial skeleton and sacroiliac joints and to a lesser extent by peripheral arthritis and the involvement of some extra-articular organs. It is paramount for the provision of effective health care delivery to be familiar with the epidemiologic studies on prevalence, mortality, and disability. Furthermore, there is no systematic arrangement of studies related to the treatment of ankylosing spondylitis in Korea. In this review, we addressed Korean ankylosing spondylitis epidemiological studies related to prevalence, genetic factor especially human leucocyte antigen-B27, extra-articular manifestations, infections, mortality, radiologic progression, child-birth, and quality of life. Furthermore, we reviewed Korean ankylosing spondylitis treatment researches about treatment trend, patients' registration program called The KOrean College of Rheumatology BIOlogics and targeted therapy (KOBIO) registry project, biologics and biosimiliars, complications especially infections, and issues about bony progression. There would be value to further studying the epidemiology and treatment of Korean ankylosing spondylitis.

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. Drugs Real World Outcomes 2022; 9:425-436. [PMID: 35590047 PMCID: PMC9392673 DOI: 10.1007/s40801-022-00299-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/09/2022] [Indexed: 11/02/2022] Open
Abstract
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.

Abstract
Biologics are effective, though costly, medications for the treatment of rheumatoid arthritis (RA). Biosimilars are medications that have no clinically meaningful differences when compared with their corresponding reference biologics but cost significantly less. The U.S. Food and Drug Administration and the European Medication Agency have approved biosimilars for adalimumab, etanercept, infliximab, and rituximab for the treatment of RA. Streamlined approval processes are expected to expedite biosimilar development while maintaining strict safety and efficacy standards. Encouragingly, many analyses have demonstrated the potential for massive healthcare savings if biosimilars are used over biologics. Challenges to biosimilar uptake, including patient and provider hesitancy, can likely be overcome with the education of all stakeholders within healthcare systems.

Abstract
Purpose This review aims to provide an overview of the impact of TNFis biosimilars, with marketing authorization, in patient-reported outcome measures (PROMs) scores and explore how PROMs endpoints might add value in biosimilars uptake in RA patients. Patients and Methods A comprehensive search of Medline, Scopus, Lilacs, and CINAHL databases was performed for papers published between January 2012 and December 2021. For inclusion, studies had to be prospective, published in a peer-reviewed journal, published in English or Spanish language; studies using PROMs as an outcome measure. After screening title and abstracts and assessing the remaining full texts fulfilling the inclusion criteria, 31 papers were used in this narrative review. Results PROMs were used as secondary outcomes in included studies. The most frequently employed domains to assess biosimilar efficacy include physical function, patient global assessment (PtGA), health-related quality of life (HRQoL), and fatigue. The results of randomized clinical trials uniformly showed that mean change in PROMs scores is comparable between biosimilar and reference biologic treatment groups. However, open-label and real-world studies revealed high rates of discontinuation of therapy, mainly for subjective worsening of disease activity or non-specific adverse events. Even without objective clinical evidence of inflammation, patients who are considered to have active disease (higher scores on PtGA) have higher discontinuation rates of biosimilars. The available information suggests that the nocebo effect is the most likely cause for the discontinuation of biosimilars. Conclusion There is scarce literature surrounding the impact of biosimilars in PROMs, especially in open-label studies. In real-life studies, biosimilars have a higher discontinuation rate than reference products. TNFis biosimilars treatment efficacy in RA depends on disease activity and other factors such as PtGA and fatigue. The nocebo effect is the best explanation for biosimilar’s discontinuation.

Abstract
The World Health Organization (WHO) guidelines on evaluation of similar biotherapeutic products (SBPs; also called biosimilars) were adopted by the WHO Expert Committee on Biological Standardization (ECBS) in 2009. In 2019, the ECBS considered that a more tailored and potentially reduced clinical data package may be acceptable in cases where this was clearly supported by the available scientific evidence. The goal of this publication is to review the current clinical experience and scientific evidence and to provide an expert perspective for updating the WHO guidelines to provide more flexibility and clarity. As the first step, the relevant guidelines by other regulatory bodies were reviewed in order to identify issues that might help with updating the WHO guidelines. Next, a literature search was conducted for information on the long-term efficacy, safety, and immunogenicity of biosimilars to identify possible long-term problems. Finally, a search for articles concerning the role of clinical studies in the benefit-risk evaluation of biosimilars was conducted. The analysis of other guidelines suggested that the WHO guidelines may need more emphasis on the importance of the state-of-the-art physicochemical and structural comparability exercise and in vitro functional testing. The use of "foreign" reference product will also need clarifications. The value of in vivo toxicological tests in the development of biosimilars is questionable, and the non-clinical part needs revisions accordingly. The concepts of "totality of evidence," "stepwise development," and "residual uncertainty" were applied in the evaluation of the clinical sections of the guideline. The review of long-term safety and efficacy demonstrated the robustness of the current biosimilar development concept. The analysis of the roles of different development phases suggested that the large efficacy, safety, and immunogenicity studies are, in most cases, redundant. The residual uncertainty of safety, immunogenicity, and efficacy of biosimilars that has shaped the current regulatory guidelines is now substantially reduced. This will allow the re-evaluation of the non-clinical and clinical requirements of the current WHO main guideline. The shift of the relative impact of the development phases towards physico-chemical and in vitro functional testing will provide a relief to the manufacturers and new challenges to the regulators.

Abstract
In der Therapie der rheumatoiden Arthritis sind seit ca. 20 Jahren Biologika ein fester Bestandteil. Da Arzneimittelpatente in der Regel nach 10 Jahren auslaufen, wurden in den letzten Jahren Biosimilars auf den Markt gebracht. In vielen Studien konnte gezeigt werden, dass sie bei vergleichbarer Sicherheit und Effektivität eine gleichwertige Alternative zum Referenzarzneimittel darstellen. In manchen Fällen zeigten sich sogar geringere Raten an unerwünschten Arzneimittelwirkungen im Vergleich zu den Referenzarzneimitteln. Weiterhin können durch Biosimilars erhebliche Kosten eingespart werden, die sich allein in Deutschland auf einen jährlichen dreistelligen Millionenbetrag belaufen. Dabei lassen sich große regionale Unterschiede bei der Verschreibungshäufigkeit von Biosimilars in Deutschland ausmachen, die sich auch im Einsparungspotenzial widerspiegeln. Eine Umstellung auf ein Biosimilar ist unter Einbezug des Patienten gut möglich und auch erwünscht. In diesem Sinne ist auch die Erstverschreibung eines Biosimilars statt des Referenzarzneimittels zu befürworten.

Abstract
Objective: Concerns exist regarding the potential development of malignancy and tuberculosis in patients with spondyloarthritis (SpA) treated with biologics. We assessed the extent to which biologic therapy may increase the risk of malignancy and tuberculosis in patients with SpA by meta-analysis to derive estimates of sparse harmful events occurring in Randomized Controlled Trials (RCTs). Methods: A systematic literature search was conducted in PubMed, EMbase, Web of Science, the Cochrane Library, and China Biology Medicine disc for RCTs evaluating the risk of sparse harmful events of biologic therapy in patients with SpA from inception through August 9, 2021. We calculated a pooled Peto OR for malignancy and tuberculosis in biologics-treated patients vs. placebo patients. The risk of bias on the included RCTs was assessed by using Cochrane Risk of Bias tool. Results: In total, 63 studies were included in this meta-analysis, and 83 patients and 7 patients developed malignancy and tuberculosis, respectively. Overall, the risk of malignancy and tuberculosis was increased in SpA patients treated with biologics compared to placebo (malignancy: Peto OR: 2.49, 95%CI: 1.61-3.87, p < 0.001; tuberculosis: Peto OR: 5.98, 95%CI: 1.29-27.76, p = 0.022). Remarkably, compared to placebo, there was higher risk of malignancy for IL-17 inhibitors (Peto OR: 3.68, 95%CI: 1.20-11.30, p = 0.023) and small molecule targeted drugs (Peto OR: 3.08, 95%CI: 1.37-6.90, p = 0.043) in peripheral SpA, and for TNF receptor-Fc fusion protein in axial SpA (Peto OR: 7.18, 95%CI: 1.21-42.69, p = 0.030). Besides, the risk of tuberculosis was higher for anti-TNFα antibody in axial SpA (Peto OR: 6.17, 95%CI: 1.03-37.13, p = 0.046). Conclusion: This meta-analysis showed an elevated risk of malignancy in patients with peripheral SpA treated with biologics, especially for IL-17 inhibitors, and small molecule targeted drugs, a slightly increased risk of malignancy in TNF receptor-Fc fusion protein in axial SpA, and increased risk of tuberculosis in patients with axial SpA treated with anti-TNFα antibody. These findings need to be validated by studies with larger population and longer follow-up.

Impact of Infliximab Biosimilar CT-P13 Dose and Infusion Interval on Real-World Drug Survival and Effectiveness in Patients with Ankylosing Spondylitis. J Clin Med 2021; 10:jcm10194568. [PMID: 34640586 PMCID: PMC8509762 DOI: 10.3390/jcm10194568] [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: 08/12/2021] [Revised: 09/16/2021] [Accepted: 09/24/2021] [Indexed: 11/28/2022] Open
Abstract
CT-P13 is an infliximab biosimilar approved for indications including ankylosing spondylitis (AS); the approved maintenance regimen is 5 mg/kg infused every 6–8 weeks. In clinical practice, modifications to infliximab dose and/or infusion interval can be beneficial to the patient. For CT-P13, real-world data on dose and/or interval adjustment are lacking. This analysis investigated the impact of such treatment pattern changes on effectiveness and drug survival up to five years for adult (≥18 years old) patients with AS in the Korean, real-world, retrospective rheumatoid arthritis and ankylosing spondylitis (RAAS) study. Overall, 337 patients with AS were identified: 219 who initiated infliximab treatment with CT-P13 (‘naïve’) and 118 who switched from reference infliximab to CT-P13 (‘switched’). Overall, 18/235 (7.7%), 110/224 (49.1%), and 101/186 (54.3%) evaluable patients had dose, infusion interval, or combined treatment pattern changes, respectively. More naïve (61.0%) versus switched (42.6%) patients had treatment pattern changes. Overall, Bath Ankylosing Spondylitis Disease Activity Index scores decreased from baseline to week 54, then remained stable; improvements were greater for patients with than without treatment pattern changes. Drug survival did not differ significantly between patients with or without treatment pattern changes. Findings suggest that adjusting dose and/or infusion interval can improve clinical outcomes for CT-P13-treated patients with AS.

Infliximab Biosimilar CT-P13 Observational Studies for Rheumatoid Arthritis, Inflammatory Bowel Diseases, and Ankylosing Spondylitis: Pooled Analysis of Long-Term Safety and Effectiveness. Adv Ther 2021; 38:4366-4387. [PMID: 34250583 DOI: 10.1007/s12325-021-01834-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 06/17/2021] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Long-term, real-world safety and effectiveness data are required to support biosimilar use. This analysis pooled 5-year findings from observational studies of infliximab biosimilar CT-P13 treatment in patients with rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and ankylosing spondylitis (AS). METHODS Patients enrolled in the CT-P13 4.2, 4.3, or 4.4 Korea/European Union registries were analysed if they had initiated infliximab treatment with CT-P13 (CT-P13 group) or had switched from reference infliximab to CT-P13 (switched to CT-P13 group). The primary objective was to investigate long-term safety by evaluating adverse events of special interest (AESIs) per the CT-P13 risk-management plan. Incidence rates per 100 patient-years (PYs) were calculated. Additional long-term safety endpoints, immunogenicity (assessments optional), and effectiveness were evaluated. RESULTS Overall, 736 patients (642 CT-P13; 94 switched to CT-P13) were analysed. Median (range) exposure to CT-P13 was 19.433 (0.03-63.11) months overall. The incidence of treatment-emergent adverse events was 69.0% (CT-P13 group) and 60.6% (switched to CT-P13 group). Infusion-related reaction/hypersensitivity/anaphylactic reaction was the most frequent AESI overall, with an incidence of 4.3828 per 100 PY (95% confidence interval: 3.3603-5.6185). For most AESIs, incidence rates per 100 PY were broadly comparable between treatment groups, considering overlapping 95% confidence intervals. At baseline, 42/445 (9.4%) and 21/59 (35.6%) evaluable patients in the CT-P13 and switched to CT-P13 groups, respectively, were antidrug antibody (ADA)-positive. After CT-P13 treatment during the study, 188/425 (44.2%) evaluable patients had ≥ 1 ADA-positive result, including 147/425 (34.6%) patients with negative or no ADA results reported at baseline. Effectiveness tended to increase over time for all indications. CONCLUSION The analysis did not identify any new safety findings for patients with RA, IBD, and AS treated with CT-P13 for up to 5 years in those who were infliximab-naïve at CT-P13 initiation, or those who had switched from reference infliximab to CT-P13. TRIAL REGISTRATION ClinicalTrials.gov identifiers: NCT02557295 (CT-P13 4.2; retrospectively registered on 23 September 2015); NCT02326155 (CT-P13 4.3; retrospectively registered on 25 December 2014); NCT02557308 (CT-P13 4.4; retrospectively registered on 23 September 2015).

Biobetters in patients with immune-mediated inflammatory disorders: An international Delphi consensus. Autoimmun Rev 2021; 20:102849. [PMID: 33974946 DOI: 10.1016/j.autrev.2021.102849] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Revised: 03/03/2021] [Accepted: 03/12/2021] [Indexed: 12/27/2022]
Abstract
Several efforts have been made to improve the available therapeutic armamentarium of patients with immune-mediated inflammatory disorders (IMIDs) leading to the development of biobetters. To date, there is no commonly accepted definition of biobetters. Sixteen physicians with expertise in the field of IMIDs from eleven countries attended a virtual international consensus meeting to provide for the first time a definition of biobetter and to identify unmet needs on this topic. Improvements in clinical outcomes and drug pharmacology were considered crucial for the definition of biobetters, while safety profile and patient acceptability were not. In addition, an appropriate balance between clinical outcomes and costs and a shared decision between physicians and patients should guide the decision to use a biobetter. Clinical studies are required to validate the biobetter definition and to investigate their role in the management of patients with IMIDs.

Abstract
Rheumatoid arthritis (RA) affects around 1.2% of the adult population. RA is one of the main reasons for work disability and premature retirement, thus substantially increasing social and economic burden. Biological disease-modifying antirheumatic drugs (bDMARDs) were shown to be an effective therapy especially in those rheumatoid arthritis (RA) patients, who did not adequately respond to conventional synthetic DMARD therapy. However, despite the proven efficacy, the high cost of the therapy resulted in limitation of the widespread use and unequal access to the care. The introduction of biosimilars, which are much cheaper relative to original drugs, may facilitate the achievement of the therapy by a much broader spectrum of patients. In this review we present the properties of original biologic agents based on cytokine-targeted (blockers of TNF, IL-6, IL-1, GM-CSF) and cell-targeted therapies (aimed to inhibit T cells and B cells properties) as well as biosimilars used in rheumatology. We also analyze the latest update of bDMARDs' possible influence on DNA methylation, miRNA expression and histone modification in RA patients, what might be the important factors toward precise and personalized RA treatment. In addition, during the COVID-19 outbreak, we discuss the usage of biologicals in context of effective and safe COVID-19 treatment. Therefore, early diagnosing along with therapeutic intervention based on personalized drugs targeting disease-specific genes is still needed to relieve symptoms and to improve the quality of life of RA patients.

Abstract
Traumatic brain injury (TBI) has both high morbidity and mortality rates and can negatively influence physical and mental health, while also causing extreme burden to both individual and society. Hitherto, there is no effective treatment for TBI because of the complexity of the brain anatomy and physiology. Currently, management strategies mainly focus on controlling inflammation after TBI. Tumor necrotizing factor alpha (TNF-α) plays a crucial role in neuroinflammation post-TBI. TNF-α acts as the initiator of downstream inflammatory signaling pathways, and its activation can trigger a series of inflammatory reactions. Infliximab is a monoclonal anti-TNF-α antibody that reduces inflammation. Herein, we review the latest findings pertaining to the role of TNF-α and infliximab in TBI. We seek to present a comprehensive clinical application prospect of infliximab in TBI and, thus, discuss potential strategies of infliximab in treating TBI.

Abstract
INTRODUCTION The use of biological agents in patients with rheumatic diseases has achieved the therapeutic target, i.e., remission or low disease activity. The share of biological agents has been growing with the approval of biosimilars, which have been recognized for their equivalent efficacy, safety, pharmacokinetics, and immunogenicity to the original as well as their reduced economic burden. AREA COVERED Biosimilars are being examined for their bioequivalence to reference products in randomized-controlled trials; however, the use of biosimilars in actual clinical practice is complicated owing to issues with switching and comorbidities. Therefore, this review describes real-world data in the rapidly evolving field of biosimilars in the treatment of rheumatoid arthritis and spondyloarthropathy, including ankylosing spondylitis and psoriatic arthritis. EXPERT OPINION According to published data, the use of biosimilars for inflammatory arthritis led to no significant inferiority in treatment outcomes and resulted in considerable cost savings in the real-world. Currently, beyond the use of biosimilars, issues with the interchangeability of biosimilars, including immunogenicity, should be addressed. Strategies to overcome these concerns will improve treatment efficacy and safety in patients with inflammatory arthritis.
