PURPOSE: Infliximab (INX) has been approved for treating Crohn disease (CD) for many years, showing promis-ing efficacy in the clinic. However, the efficacy of the drug and the prognosis of CD vary significantly with dif-ferent locations of disease pathology. This study evaluated the efficacy of INX and prognosis in CD in different locations of disease pathology using systematic meta-analysis. METHODS: We used "Infliximab OR Remicade OR Avakine OR Inflectra OR Renflexis OR Remsima OR IgG1k monoclonal antibody" AND "Crohn's disease OR IBD OR inflammatory bowel disease" as search strategies for searching in PubMed, Wanfang and Embase...

Hydrogen exchange-mass spectrometry (HX-MS) is widely recognized for its potential utility for establishing the equivalence of the higher-order structures of proteins, particularly in comparability and similarity contexts. However, recent progress in the statistical analysis of HX-MS data has instead placed an emphasis on significance testing to identify regions of proteins where there are significant differences in HX between two or more protein states. In the cases involving assessment of similarity or equivalence of the higher-order structure of different protein samples (e...

The effect of switching from originator infliximab to biosimilar infliximab in patients with sarcoidosis is unknown. The objective of this study is to investigate the effect of switching from Remicade® or Inflectra® to Flixabi® in patients with severe refractory sarcoidosis. This single center retrospective cohort study was performed at St Antonius Hospital Nieuwegein, The Netherlands. All patients diagnosed with severe refractory sarcoidosis receiving Remicade® or Inflectra® switched to Flixabi® . The primary outcome was infliximab discontinuation within 6 months of switching...

OBJECTIVE: To examine whether non-medical switching of patients with inflammatory bowel disease (IBD) from originator infliximab to a biosimilar (CT-P13, Inflectra) is safe and clinically non-inferior to continued treatment with originator infliximab. DESIGN: Prospective, open label, multicentre, parallel cohort, non-inferiority study in seven Australian hospitals over 48 weeks, May 2017 - October 2019. PARTICIPANTS: Adults (18 years or older) with IBD receiving maintenance originator infliximab (Remicade) who had been in steroid-free clinical remission for at least 12 weeks...

INTRODUCTION: Acute graft-versus-host disease (aGVHD) is a significant immune-mediated complication of allogeneic hematopoietic stem cell transplant (HSCT). Despite prophylactic immunosuppression, the incidence of grades II-IV aGVHD post-HSCT varies from 20 to 80%. Tumor necrosis factor (TNF) is an important cytokine involved in the pathogenesis of GVHD, and medications such as infliximab (Remicade®) have been utilized as second-line treatment options in patients with steroid-refractory GHVD...

From the regulatory point of view a strong link between an animal model and human pharmacodynamics of biological drugs is very important to qualify the model as "relevant". Consistent changes in cell population between human physiology and animal model gain value of this model which then can be pharmacodynamically "relevant" from the regulatory point of view. Consequently, the aim of this study was to determine how similar to human observations is the effect of selected biological drugs on blood cells in a pig model...

Biologic drugs have revolutionized the treatment of psoriasis and other chronic inflammatory diseases. In recent years, many tumor necrosis factor-alpha 'biosimilar' agents have been developed. These biosimilars are similar in structure and function to their originator molecules, although they are not identical. Given that the safety and efficacy of the original biologic have already been proven, biosimilars are only required to show bioequivalence, or non-inferiority, to the reference biologic to be approved...

BACKGROUND: SB2 (Renflexis®, Merck) and CT-P13 (Inflectra®, Pfizer) are biosimilars of the reference Infliximab (Remicade®, Janssen) and are approved in Canada for use in indications for which Infliximab is approved, including inflammatory bowel disease. These biosimilars are structurally different but exhibit comparable physicochemical characteristics, pharmaceutical effectiveness and immunogenicity compared to Infliximab. Optimal Infliximab therapy currently relies on therapeutic drug monitoring offered by several reference laboratories...

BACKGROUND AND AIMS: Biosimilar approval, such as Inflectra™ (CT-P13) for treating ulcerative colitis (UC) and Crohn's disease (CD), has reduced direct drug costs. Though clinicians are comfortable with biosimilar use in treatment-naïve patients, there are concerns in some jurisdictions that there are insufficient data from well-controlled trials to support non-medical switching. A systematic review, along with a critical assessment of the study design, was conducted to assess the potential impact of switching stable CD/UC patients from infliximab to CT-P13...

BACKGROUND: A significant percentage of patients receiving anti-tumor necrosis factor alpha (anti-TNFα) agents lose clinical response over time. This study aims to provide representative real-world data on anti-TNFα drug sustainability, prevalence and predictors of anti-TNFα dose escalation. METHODS: In this nationwide, retrospective study, patients receiving infliximab or adalimumab therapy between 2013 and 2016 were included using the administrative claims database of the Hungarian National Health Insurance Fund...

BACKGROUND: To lighten the burden on health-care spending, switching from the infliximab originator to a biosimilar in patients with inflammatory bowel disease (IBD) is advocated. However, the uptake of biosimilars lacks initiatives aimed at educating patients. AIMS: To explore the impact of a gastroenterologist's interview on IBD patients' acceptance for switching from infliximab bio-originator Remicade® to its biosimilar CT-P13 Inflectra®. METHODS: After the interview of 138 included patients, 120 properly responded to a self-administered questionnaire to collect consent about the switch and relevant data...

Biosimilars are new drugs, highly similar copies of biological medicines, equally effective and safe but at lower prices. The aim of this brief review is to provide the current status of biosimilars approved in the European Union for dermatological use. We used PubMed for literature search up to June 2018. The keyword 'biosimilars' was searched and 1,691 items were found. From the 1,691 studies, we included 34 articles in our review. Biologics, biosimilars and generics are different types of drugs. Biosimilars are complex molecules produced by a difficult manufacturing process, and changes in product quality may affect its safety and efficacy...

BACKGROUND AND OBJECTIVE: Regulatory approval of biosimilars often depends on extrapolating evidence from one clinical indication to all of those of the originator biologic. We aimed to develop a quantitative benefit-risk analysis to assess whether the resulting increase in the uncertainty in the clinical performance of biosimilars (i.e. risk) may be countered by their lower pricing (benefit). METHODS: A 1-year decision-analytic model was developed for the biosimilar infliximab (Inflectra® ) for Crohn's disease...

BACKGROUND: There are two products in which infliximab is the active pharmaceutical ingredient. These are Remicade® (INF; reference product) and Remsima™/Inflectra™ (CT-P13; infliximab biosimilar). Remsima™/Inflectra™ are bioidentical products. Different recommendations have been made for the clinical solutions of each brand (Remicade® or Remsima™/Inflectra™) despite the manufacturer of the biosimilar claiming high levels of similarity to the innovator. OBJECTIVE: The objective of this study was to assess and compare stability against degradation and over time of different clinical infliximab solutions prepared from Remicade® and from Remsima™/Inflectra™ using a suitable set of characterization methods in line with the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) recommendations...

INTRODUCTION: TNF-α-neutralizing antibodies, such as infliximab (IFX) and adalimumab (ADA), are effective in the treatment of inflammatory bowel diseases (IBD), but they are expensive and become ineffective when patients develop anti-IFX or anti-ADA antibodies (ATI and ATA, respectively). Second-generation anti-TNF-α antibodies, such as Golimumab, Etanercept, Certolizumab-pegol and IFX biosimilars, may solve these issues. AIM: To determine the neutralizing capacity of first- and second generation anti-TNF-α antibodies and to determine whether ATI show cross-reactivity with the IFX biosimilar CT-P13 (Inflectra)...

Immune-mediated inflammatory diseases share several pathogenic pathways and this pushes sometimes to extrapolate from one disease or indication to others. A biosimilar can be defined as a biotherapeutic product which is similar in terms of quality, safety, and efficacy to an already licensed reference biotherapeutic product. We review the substrate for extrapolation, the current approval process for biosimilars and the pioneering studies on biosimilars performed in rheumatoid arthritis patients. A biosimilar has the same amino acid sequence as its innovator product...

Background: The advent of Remicade® biosimilars, Remsima®, Inflectra® and, more recently, Flixabi®, has brought along the potential to decrease the costs associated with this therapy, therefore increasing its access to a larger group of patients. However, and in order to assure a soft transition, one must make sure the assays and algorithms previously developed and optimized for Remicade perform equally well with its biosimilars. This study aimed to: (a) validate the utilization of Remicade-optimized therapeutic drug monitoring assays for the quantification of Flixabi; and (b) determine the existence of Remicade, Remsima and Flixabi cross-immunogenicity...

OBJECTIVES: The aim of the study was to summarize short-term effectiveness, safety, and cost of using infliximab biosimilar (IFX-B) drugs, (Inflectra [Hospira] and Remsima [NAAP]) compared to originator infliximab (IFX-O) (Remicade [MSD]) in biologic naive pediatric inflammatory bowel disease in the United Kingdom. METHODS: Prospective audit of patients starting anti-tumour necrosis factor (TNF) therapy. Disease severity, response to treatment, and remission rate was measured by Pediatric Crohn's Disease Activity Index (PCDAI) and/or Physician Global Assessment...
