Abstract
We examined the assay formats used to detect anti-drug antibodies (ADA) in clinical studies of the anti-tumour necrosis factor (TNF) monoclonal antibodies adalimumab and infliximab in chronic inflammatory disease and their potential impact on pharmacokinetic and clinical outcomes. Using findings of a recent systematic literature review of the immunogenicity of 11 biological/biosimilar agents, we conducted an ancillary qualitative review of a subset of randomized controlled trials and observational studies of the monoclonal antibodies against anti-TNF factor adalimumab and infliximab. Among studies of adalimumab and infliximab, the immunoassay method used to detect antibodies was reported in 91 of 111 (82%) and 154 of 206 (75%) adalimumab and infliximab studies, respectively. In most adalimumab and infliximab studies, an enzyme-linked immunosorbent assay or radioimmunoassay was used [85 of 91 (93%) and 134 of 154 (87%), respectively]. ADA incidence varied widely among assays and inflammatory diseases (adalimumab, 0-87%; infliximab, 0-79%). Pharmacokinetic and clinical outcomes were only reported for ADA-positive patients in 38 of 91 (42%) and 61 of 154 (40%) adalimumab and infliximab studies, respectively. Regardless of assay format or biological used, ADA formation was associated with lower serum concentrations, reduced efficacy and elevated rates of infusion-related reactions. Consistent with previous recommendations to improve interpretation of immunogenicity data for biologicals, greater consistency in reporting of assay methods and clinical consequences of ADA formation may prove useful. Additional standardization in immunogenicity testing and reporting, application of modern, robust assays that satisfy current regulatory expectations and implementation of international standards for marketed products may help to improve our understanding of the impact of immunogenicity to biologics.

Abstract
OBJECTIVES A systematic review was conducted to explore the immunogenicity of biologic agents across inflammatory diseases and its potential impact on efficacy/safety. METHODS Literature searches were conducted through November 2016 to identify controlled and observational studies of biologics/biosimilars administered for treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), juvenile idiopathic arthritis (JIA), ankylosing spondylitis (AS), non-radiographic axial spondyloarthritis (nr-axSpA), psoriasis (Ps), Crohn's disease, and ulcerative colitis. RESULTS Of >21,000 screened publications, 443 were included. Anti-drug antibody (ADAb) rates varied widely among biologics across diseases (and are not directly comparable because of immunoassay heterogeneity); the highest overall rates were reported with infliximab (0-83%), adalimumab (0-54%), and infliximab biosimilar CT-P13 (21-52%), and the lowest with secukinumab (0-1%), ustekinumab (1-11%), etanercept (0-13%), and golimumab (0-19%). Most ADAbs were neutralizing, except those to abatacept and etanercept. ADAb+ versus ADAb- patients had lower rates of clinical response to adalimumab (RA, PsA, JIA, AS, Ps), golimumab (RA), infliximab (RA, PsA, AS, Ps), rituximab (RA), ustekinumab (Ps), and CT-P13 (RA, AS). Higher rates of infusion-related reactions were reported in infliximab- and CT-P13-treated ADAb+ patients. Background immunosuppressives/anti-proliferatives reduced biologic immunogenicity across diseases. CONCLUSIONS Based on reviewed reports, biologic/biosimilar immunogenicity differs among agents, with the highest rates observed with infliximab and adalimumab. As ADAb formation in biologic-/biosimilar-treated patients may increase the risk of lost response, the immunogenicity of these agents is an important (albeit not the only) consideration in the treatment decision-making process.

Abstract
BACKGROUND The infliximab originator's patent recently expired, leading to the production of biosimilar versions of the drug. The biosimilars' efficacy was not tested on patients with psoriasis but most regulatory authorities approved their use in psoriasis because of an extrapolation of data from studies conducted in other diseases. OBJECTIVE We sought to describe the use of the infliximab biosimilar (Remsima; CT-P13) in patients with psoriasis. METHODS Objective (Psoriasis Area and Severity Index) and subjective (visual analog pain scale) measurements of disease activity were collected in 2 cohorts of patients with moderate to severe plaque psoriasis: cohort 1 patients switched from the infliximab originator to the infliximab biosimilar; and cohort 2 patients were infliximab-naïve and started on the infliximab biosimilar. RESULTS We observed no changes of Psoriasis Area and Severity Index and visual analog pain scale scores in 30 patients who switched from the infliximab originator to the biosimilar. Four of 5 infliximab-naïve patients who started infliximab biosimilar treatment achieved 75% improvement or better from baseline Psoriasis Area and Severity Index score at the end of the induction phase. LIMITATIONS Number of patients and length of follow-up was limited. CONCLUSIONS Patients with psoriasis taking infliximab originator treatment can switch to the infliximab biosimilar without experiencing a significant change in clinical response or additional adverse events. The use of the infliximab biosimilar could reduce the growing pressure on health care budgets.

Abstract
Biopharmaceuticals or 'biologics' have revolutionized the treatment of many diseases. However, some patients generate an immune response to such drugs, potentially limiting clinical efficacy and safety. Infliximab (Remicade(®)) is a monoclonal antibody used to treat several immune-mediated inflammatory disorders. A biosimilar of infliximab, CT-P13 (Remsima(®), Inflectra(®)), has recently been approved in Europe for all indications in which infliximab is approved. Approval of CT-P13 was based in part on extrapolation of clinical trial data from two indications (rheumatoid arthritis and ankylosing spondylitis) to all other indications, including inflammatory bowel disease. This review discusses the validity of extrapolating immunogenicity data across indications - a process adopted by the EMA as part of their biosimilar approval process - with a focus on CT-P13.

Abstract
The introduction of biologic drugs represents the most significant advance in the management of immune-mediated inflammatory diseases for a decade. However, complex proteins are expensive to produce and manufacture. Biosimilar versions of established biologics are becoming available as another version of the reference medicinal product and are expected to provide substantial cost savings. However, because of their complexity, the approval of biosimilars requires strict controls to ensure that all therapeutically relevant characteristics are comparable to the reference medicinal product. This review summarizes the scientific principles and data requirements underpinning regulatory approval of biosimilars and the assumptions that enable extrapolation of data between indications. These important concepts are exemplified by CT-P13 (Remsima(®), Inflectra(®)), the first biosimilar monoclonal antibody approved in Europe.

Abstract
The development of biologic drugs has undoubtedly enhanced the spectrum of treatments available for immune-mediated inflammatory rheumatic diseases such as rheumatoid arthritis. However, despite their clear clinical benifits, use of biologics is often hindered by their high costs. The manufacture and subsequent approval of more cost-effective 'biosimilar' versions of these drugs may address this issue and improve patient access. CT-P13 (Remsima(®), Inflectra(®)), a biosimilar of infliximab (Remicade(®)), has shown comparable efficacy, safety and pharmacokinetics to its originator drug in clinical studies. The articles in this supplement present a scientific update on the development and use of biosimilars in rheumatic disorders, with specific focus on CT-P13. The information discussed highlights the predicted positive clinical and economic impact of biosimilars on the management of rheumatic diseases.

Abstract
The introduction of targeted biological therapies has revolutionised the management of immune-mediated inflammatory diseases (IMIDs) such as rheumatoid arthritis, ankylosing spondylitis, psoriasis and inflammatory bowel disease. Following treatment with these therapies, many patients experience significant improvements in different aspects of their disease, including symptoms, work productivity and other outcomes relevant for individuals and society. However, due to the complexity of biological drug development and manufacturing processes, the costs of these therapies are relatively high. Indeed, the financial burden on healthcare systems due to biological therapies is considerable and lack of patient access to effective treatment remains a concern in many parts of the world. As many reference biological therapies have now reached or are near to patent expiry, a number of 'biosimilar' drugs have been developed for use in various clinical settings, and some of these drugs are already in use in several countries. While the potential pharmacoeconomic benefits of cost-effective biosimilars seem clear, several issues have been raised regarding, for example, the definition of biosimilarity and the validity of indication extrapolation, as well as the 'switchability' and relative immunogenicity of biosimilars and their reference drugs. In this review, these issues will be discussed with reference to CT-P13, a biosimilar of the anti-tumour necrosis factor monoclonal antibody infliximab, which is approved in Europe and elsewhere for the treatment of various IMIDs. Other important issues, including those related to data collection during nonclinical and clinical development of biosimilars, are also discussed.

Abstract
Biosimilars are biologic medical products whose active drug substance is made by a living organism or derived from it. The term is used to describe a subsequent version of an innovator biopharmaceutical product aiming at approval following patent expiry on the reference product. Biosimilars of monoclonal need to demonstrate similar but not identical quality of nonclinical and clinical attributes. Not all data of the originator product need to be recapitulated, as large numbers of patient-years of exposure data are already available. Thus, biosimilar development is largely based on the safety profiles of the originator product. The evaluation of biosimilarity includes immunogenicity attributed risks. CT-P13 (Remsima™/Inflectra™, Celltrion/Hospira), a biosimilar of the innovator drug infliximab (INF), was the first approved complex biosimilar monoclonal antibody in the EU, within the framework of WHO, EMA and US FDA biosimilar guidelines. CT-P13 has shown analytical and nonclinical features highly similar to INF including pharmacokinetics, efficacy, safety and immunogenicity profiles in ankylosing spondylitis and rheumatoid arthritis. The objective of this article is to highlight the recent biosimilar development and to review the results from the studies PLANETRA and PLANETAS, which have supported the approval of CT-P13 for several indications.
