Efficacy and safety of biosimilar infliximab in bio-naïve patients with Crohn's disease. Arab J Gastroenterol 2024; 25:257-262. [PMID: 38714472 DOI: 10.1016/j.ajg.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/09/2024] [Accepted: 03/23/2024] [Indexed: 05/10/2024]
Abstract
BACKGROUND AND STUDY AIMS The infliximab biosimilar CT-P13 was the first biosimilar drug targeting tumor necrosis factor-α. However, its efficacy and safety in real-world clinical situations have remained insufficient. Therefore, we aimed to verify the efficacy and safety of CT-P13 in bio-naïve patients with Crohn's disease. PATIENTS AND METHODS This retrospective multicenter study compared the remission rate at week 54 between patients with Crohn's disease who were treated with originator infliximab or CT-P13. Endoscopic and laboratory findings were assessed in both groups. A total of 184 (156 originator and 28 CT-P13) patients were analyzed. Of these, 138 originator users and 19 biosimilar users completed 54-week administration. RESULTS The clinical remission rates in patients taking originator infliximab of CT-P13 at week 54 were 92.5 % and 100 %, respectively. The endoscopic scores of each group significantly decreased from baseline at week 54 in both groups, and the mucosal healing rate at week 54 was 53 % and 64 %, respectively. Laboratory data including C-reactive protein, serum albumin, and hemoglobin significantly improved from baseline to week 14 and 54 in both groups. Adverse events were observed more frequently in the CT-P13 group (25 % vs. 4.5 %, p = 0.0015), but severe adverse events were rare in both groups. CONCLUSION The efficacy and safety of CT-P13 were comparable with those of originator infliximab in bio-naïve patients with Crohn's disease evaluated by clinical, endoscopic, and laboratory findings. This study establishes the needed groundwork for the development of a strategy for treatment with biologics in patients with Crohn's disease.

Abstract
Background Data on safety and efficacy of switching to Renflexis (SB2) from originator Infliximab (IFX) (single switch) or from originator IFX to Inflectra (CT-P13) to Renflexis (double switch) are limited. Methods We conducted a retrospective cohort study in a nationwide cohort of patient with inflammatory bowel disease (IBD) in remission who were switched to SB2. The main exposure was the treatment course of SB2. There are 2 levels in this variable: single switch (IFX to SB2) and double switch (IFX to CT-P13 to SB2). The outcome is SB2 drug discontinuation rate and/or not being in remission after 1 year. Logistic regression was used to estimate the adjusted and unadjusted odds ratios with 95% confidence intervals to study the efficacy difference between single switch and double switch. Results A total of 271 IBD patients were started on SB2. Among them 52 (19.2%) patients did not achieve remission at 1 year and 14 (5.1%) patients had to discontinue SB2 due to adverse events). In logistic regression analysis after controlling for covariates, there was no statistically significant difference observed in regard to efficacy or safety of the single switch versus double switch to SB2 (adjusted odds ratio for double switch compared to single switch = 1.33 (95% confidence interval 0.74-2.41, P = 0.3432). Conclusions Among IBD patients in remission, double switch was equally effective as compared to a single switch. This will help reassure the gastroenterologists who have concerns regarding the safety and efficacy of switching between multiple biosimilars for treating IBD.

Abstract
Healthcare systems worldwide are struggling to find ways to fund the cost of innovative treatments such as gene therapies, regenerative medicine, and monoclonal antibodies (mAbs). As the world's best known mAbs are close to facing patent expirations, the biosimilars market is poised to grow with the hope of bringing prices down for cancer treatment and autoimmune disorders, however, this has yet to be realized. The development costs of biosimilars are significantly higher than their generic equivalents due to therapeutic equivalence trials and higher manufacturing costs. It is imperative that academics and relevant companies understand the costs and stages associated with biologics processing. This article brings these costs to the forefront with a focus on biosimilars being developed for Rheumatoid Arthritis (RA). mAbs have remarkably changed the treatment landscape, establishing their superior efficacy over traditional small chemicals. Five blockbuster TNFα mAbs, considered as first line biologics against RA, are either at the end of their patent life or have already expired and manufacturers are seeking to capture a significant portion of that market. Although in principle, market-share should be available, withstanding that the challenges regarding the compliance and regulations are being resolved, particularly with regards to variation in the glycosylation patterns and challenges associated with manufacturing. Glycan variants can significantly affect the quality attributes requiring characterization throughout production. Successful penetration of biologics can drive down prices and this will be a welcome change for patients and the healthcare providers. Herein we review the biologic TNFα inhibitors, which are on the market, in development, and the challenges being faced by biosimilar manufacturers.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease linked to oxidative stress, which is associated with significant morbidity. The NADPH oxidase complex (NOX) produces reactive oxygen species (ROS) that are among the key markers for determining RA’s pathophysiology. Therefore, understanding ROS-regulated molecular pathways and their interaction is necessary for developing novel therapeutic approaches for RA. Here, by combining mouse genetics and biochemistry with clinical tissue analysis, we reveal that in vivo Rubicon interacts with the p22phox subunit of NOX, which is necessary for increased ROS-mediated RA pathogenesis. Furthermore, we developed a series of new aryl propanamide derivatives consisting of tetrahydroindazole and thiadiazole as p22phox inhibitors and selected 2-(tetrahydroindazolyl)phenoxy-N-(thiadiazolyl)propanamide 2 (TIPTP, M.W. 437.44), which showed considerably improved potency, reaching an IC50 value up to 100-fold lower than an inhibitor that we previously synthesized reported N8 peptide-mimetic small molecule (blocking p22phox–Rubicon interaction). Notably, TIPTP treatment showed significant therapeutic effects a mouse model for RA. Furthermore, TIPTP had anti-inflammatory effects ex vivo in monocytes from healthy individuals and synovial fluid cells from RA patients. These findings may have clinical applications for the development of TIPTP as a small molecule inhibitor of the p22phox-Rubicon axis for the treatment of ROS-driven diseases such as RA.

Abstract
Introduction: Biological drugs have revolutionized the treatment of various medical conditions. Recently, upon expiration of patents of a few biological agents, biosimilars are being rapidly developed as an affordable substitute for more expensive biologic drugs, which may serve as a therapeutic alternative for biologics reference medical product (RMP). Prior to approval for use of the biosimilar drug for treatment of RMP indications, a process involving several different assays is required, in which the biosimilar must prove to posses no meaningful differences from an existing approved RMP in terms of purity, safety and potency.Areas covered: This report describes the different assays which are used to assess biosimilar drugs using CT-P13 infliximab biosimilar as a case-in-point. It covers the assays of physicochemical characterization, biological activity, and immunogenicity and examines their rational along with methodological and conceptual caveats clinicians should be cognizant of.Expert opinion: The approval of a biosimilar is a complex process that requires several assays, specifically tailored to the characteristics of the RMP. Determining the required assays and the allowable margin of confidence are of great importance but are not sufficient in order to prove that the biosimilar is indeed not inferior in its clinical potency and safety to the RMP.

Abstract
Background: Anti-tumor necrosis factor (anti-TNF) monoclonal antibodies have
revolutionized the treatment of inflammatory bowel diseases (IBD). However, because of
their complexity, their production is expensive contributing to their high price. As the patent
protection of these therapies has expired in several countries, biosimilars have been developed
to reduce the healthcare costs. The aim of this article is to review the literature on the
safety, efficacy and immunogenicity of biosimilars in IBD.
</P><P>
Methods: A PubMed literature search was performed using the following terms until May
2016: ‘biosimilars’, ‘CT-P13’, ‘infliximab’, ‘Crohn’s disease’, ‘ulcerative colitis’, ‘inflammatory
bowel diseases’, ‘efficacy’, ‘safety’, ‘immunogenicity’. Additionally, abstracts from international
meetings were also reviewed.
</P><P>
Results: A total of eleven studies in IBD patients provided real-world evidence on the efficacy,
safety and immunogenicity profile of biosimilars in IBD patients. Based on the available
evidence, CT-P13 is efficacious and well tolerated in IBD patients in a real-life setting.
The vast majority of studies only included IBD patients who had never received biological
therapies. Information regarding the interchangeability between CT-P13 and its originator is
currently being investigated in the NOR-SWITCH trial. Otherwise, the immunogenicity profile
of CT-P13 seems to be similar to the originator.
</P><P>
Conclusion: The infliximab biosimilar seems to be efficacious, safe and with a similar immunogenicity
profile as the originator in IBD. Large prospective post-marketing studies are
needed to assess the long-term safety profile of CT-P13. The use of infliximab biosimilars
may lead to major healthcare cost savings.

Abstract
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). METHODS TNF-α neutralization was measured using a quantitative TNF-α sensor assay consisting of HeLa 8D8 cells that express the Green Fluorescence Protein (GFP) under control of a NF-кB response element. All available anti-TNF-α drugs and the IFX biosimilar CT-P13 (Inflectra) were tested for their TNF-α-neutralizing capacity. In addition, patient sera with ATI were tested for their potential to block the activity of IFX, IFX (F)ab2-fragment, biosimilar CT-P13 (Inflectra) and ADA. RESULTS TNF-α strongly induced GFP expression in Hela 8D8 cells. Higher concentrations of first-generation anti-TNF-α drugs were required to neutralize TNF-α compared to the second-generation anti-TNF-α drugs. Serum of IBD patients with proven ATI blocked TNF-α-neutralizing properties of IFX biosimilar CT-P13 (Inflectra), whereas such sera did not block the effect of ADA. CONCLUSION The second-generation anti-TNF-α drugs show increased TNF-α-neutralizing potential compared to first-generation variants. ATI show cross-reactivity toward IFX biosimilar CT-P13 (Inflectra), consequently patients with ATI are unlikely to benefit from treatment with this IFX biosimilar.

Abstract
BACKGROUND CT-P13, the first biosimilar monoclonal antibody to infliximab (IFX), has previously been confirmed to be efficacious in inducing mucosal healing in ulcerative colitis (UC) patients. The aim of this study was to evaluate the efficacy of CT-P13 therapy in maintaining mucosal healing in UC. METHODS CT-P13 trough levels, antibody positivity, serum inflammatory markers as CRP level, fecal calprotectin at weeks 14 and 54, concomitant steroid and azathioprine therapy at the time of induction therapy and at weeks 14 and 54, previous use of anti TNF drug and the need of dose intensification as possible predictive factors for mucosal healing at week 54 were evaluated in this prospective study. RESULTS 61 patients had already completed the 54-week treatment period. Mucosal healing was shown in 65.5 % and 62.1 %, complete mucosal healing was present in 31% and 38 % at week 14 and 54, respectively. The median values of CRP, leukocytes, thrombocytes, and albumin showed significant difference between baseline and week 54. Serum antibody positivity was proved in 6.5 % and 19.7 % of cases at week 14 and 54, respectively. CONCLUSION Our study confirmed the long-term efficacy of CT-P13 therapy on mucosal healing in UC.

Update on biosimilars in inflammatory bowel disease: Position and recommendations in Mexico. REVISTA DE GASTROENTEROLOGIA DE MEXICO (ENGLISH) 2018; 83:414-423. [PMID: 29685744 DOI: 10.1016/j.rgmx.2018.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2017] [Revised: 03/02/2018] [Accepted: 03/06/2018] [Indexed: 06/08/2023]
Abstract
The biotechnology-derived medicines known as biosimilars are defined as non-originator treatments that have demonstrated quality, efficacy, and safety comparable to the reference biologic drug. Clinical trials have shown that the infliximab biosimilar, CT-P13, and the candidates for the adalimumab biosimilars, ABP 501 and ZRC 3197, are not significantly different, with respect to efficacy and safety, from the originator drugs in patients with other autoimmune diseases. However, controversy has arisen over the use of biosimilars in inflammatory bowel disease, due to the incipient evidence not only in patients with no previous biotechnology treatment, but also in patients in remission, that could be switched to a biosimilar for non-medical reasons. The present review is the first critical analysis by different specialists in the area of gastroenterology on the use of biosimilars in inflammatory bowel disease, the evidence on interchangeability, the extrapolation of indications, efficacy, safety, immunogenicity, and the clinical impact of the Mexican health regulations. The aim of our review was to make the positioning and recommendations of these new therapeutic options known, given that they have a potential cost-benefit for both patients and healthcare institutions.

Abstract
Objective CT-P13 is a biosimilar with comparable pharmacokinetics, efficacy and safety to its reference product (RP), infliximab. Studies have shown that switching from RP to CT-P13 does not reduce the effectiveness or safety of treatment. Methods In this retrospective real-world study, patients with inflammatory diseases treated with RP were switched to CT-P13 (n = 7) or continued on RP (n = 6). Clinical outcomes were compared between groups after four treatment cycles. Results CT-P13 demonstrated comparable effectiveness to its RP. All patients who switched to the biosimilar maintained or improved their clinical response, including two who remained in remission and three who moved into remission. In the RP group, five patients maintained their clinical response, with one achieving remission. Safety profiles were similar between groups. Conclusions CT-P13 was equally effective as infliximab RP in this real-world study. CT-P13 is a valid, lower-cost alternative for patients currently receiving RP.

Abstract
Background We studied the comparative effectiveness of biosimilar filgrastim vs original filgrastim in patients with chemotherapy-induced neutropenia. Patients and methods This multicenter, observational study was conducted at 14 centers. The study included 337 patients experiencing neutropenia under chemotherapy. Patients were given either filgrastim 30 MIU or 48 MIU (Neupogen®) or biosimilar filgrastim 30 MIU (Leucostim®). Data regarding age, chemotherapeutic agents used, number of chemotherapy courses, previous diagnosis of neutropenia, neutrophil count of patients after treatment, medications used for the treatment of neutropenia, and duration of neutropenia were collected. Time to absolute neutrophil count (ANC) recovery was the primary efficacy measure. Results Ambulatory and hospitalized patients comprised 11.3% and 45.1% of the enrolled patients, respectively, and a previous diagnosis of neutropenia was reported in 49.3% of the patients, as well. Neutropenia occurred in 13.7% (n=41), 45.5% (n=136), 27.4% (n=82), 11.4% (n=34), and 2.0% (n=6) of the patients during the first, second, third, fourth, and fifth cycles of chemotherapy, respectively. While the mean neutrophil count was 0.53±0.48 before treatment, a significant increase to 2.44±0.66 was observed after treatment (p=0.0001). While 90.3% of patients had a neutrophil count <1.49 before treatment, all patients had a neutrophil count ≥1.50 after treatment. Neutropenia resolved within ≤4 days of filgrastim therapy in 60.1%, 56.7%, and 52.6% of the patients receiving biosimilar filgrastim 30 MIU, original filgrastim 30 MIU, and original filgrastim 48 MIU, respectively. However, there was no significant difference between the three arms (p=0.468). Similarly, time to ANC recovery was comparable between the treatment arms (p=0.332). Conclusion The results indicate that original filgrastim and biosimilar filgrastim have comparable efficacy in treating neutropenia. Biosimilar filgrastim provides a valuable alternative; however, there is need for further studies comparing the two products in different patient subpopulations.

Abstract
The treatment goal for children suffering from inflammatory bowel disease has been evolving with biologic therapies like anti-tumor necrosis factor agents assuming a more central role in treatment of more aggressive and extensive phenotype. Earlier introduction of anti-tumor necrosis factor agents have shown to be more effective and may even alter the natural history of inflammatory bowel disease. Development of anti-drug antibodies, however, limits long-term usage and leads to dose adjustment in almost half of patients treated with these medications. One of the strategies to minimize the development of anti-drug antibodies has been concomitant use of immunomodulator medications, resulting in fewer infusion reactions and sustained trough levels, potentially lowering the need for dose adjustments. Balanced with these benefits of optimized dosing and likely more sustained response, however, is the concern about increased risk of complications, such as infections and malignancies. The current manuscript reviews the available pediatric literature regarding efficacy, safety, and side effect profile of combination (immunomodulator and biologics) therapy in pediatric Crohn disease and ulcerative colitis, with particular emphasis on cost constraints, and recommendations for selection of patients who would benefit most from combination therapy.

Abstract
INTRODUCTION By definition, biosimilars are similar to a biological reference that has already received marketing authorization for biologic drugs.The purpose of biosimilars is reducing costs, thus increasing access to this treatment, however, the concerns of health professionals and users refer to the fact that to reduce costs will not neglecting the quality, effectiveness and especially security. OBJECTIVE The aim of this study is then to assess the degree of similarity between the biosimilar and its reference biopharmaceuticals, trying to understand the production process, requirements necessary for approval, and its impact on the quality, safety, efficacy and costs. METHODS For the systematic review without meta-analysis, we researched articles to the b-on, Pubmed and Medscape to 2005-2014, and selected 23 articles that contributed to the verification of the objectives of this study. RESULTS Several studies indicate that overall the biosimilar and biological reference showed no significant differences except those inherent to the production process, being the first susceptible to comparability tests demonstrating the similarity in terms of clinical efficacy and safety. CONCLUSION Biosimilars will be increasingly present in the future as promising therapeutic arsenal and targeted therapy, however, issues related to immunogenicity, interchangeability, automatic substitution and extrapolation of indications should continue to be studied and debated.

Abstract
BACKGROUND Biosimilars of anti-tumour necrosis factor (TNF)-α agents have now become clinically available for the treatment of inflammatory bowel diseases (IBD). AIM To perform a systematic review and meta-analysis to evaluate the efficacy and safety of biosimilars of anti-TNF-α agents in patients with IBD. METHODS Electronic databases were searched. The outcomes were the pooled rates of clinical response or remission, sustained clinical response or remission, and adverse events in patients with IBD induced with or switched to biosimilars of anti-TNF-α agents. RESULTS Eleven observational studies reporting outcomes in 829 patients treated with biosimilar of infliximab (CT-P13) were identified. The pooled rates of clinical response among Crohn's disease (CD) and ulcerative colitis (UC) at 8-14 weeks were 0.79 (95% confidence interval (CI) = 0.65-0.88) and 0.74 (95% CI = 0.65-0.82), respectively, and at 24-30 weeks were 0.77 (95% CI = 0.63-0.86) and 0.77 (95% CI = 0.67-0.85) respectively. Adverse events were rare (CD, 0.08 (95% CI = 0.02-0.26); UC, 0.08 (95% CI = 0.03-0.17)). The pooled rates of sustained clinical response among CD and UC after switching from infliximab to CT-P13 at 30-32 weeks were 0.85 (95% CI = 0.71-0.93) and 0.96 (95% CI = 0.58-1.00), respectively, and at 48-63 weeks were 0.75 (95% CI = 0.44-0.92) and 0.83 (95% CI = 0.19-0.99) respectively. Adverse events were rare (CD, 0.10, 95% CI = 0.02-0.31; UC, 0.22, 95% CI = 0.04-0.63). CONCLUSIONS CT-P13 was associated with excellent clinical efficacy and safety profile, supporting its use in the treatment of IBD.

Abstract
Early biologic therapy is recommended in patients with inflammatory bowel disease and poor prognostic factors and in those refractory to conventional medications. Anti-tumor necrosis factor (anti-TNF) agents are the most commonly used biologic agents. However, some patients may not have an initial response to anti-TNF therapy, and one-third will develop loss of response over time. Anti-TNF drugs can also be associated with side effects. In addition, the use of biologics is currently limited by their cost, especially in developing countries. A number of new therapeutic targets, including novel small molecules, and cellular therapy are available or under investigation. These novel molecules include oral Janus kinase (JAK) inhibitor (tofacitinib), interleukin inhibitor (ustekinumab), oral SMAD7 antisense oligonucleotide (mongersen), and anti-integrin inhibitors (vedolizumab). Here, we review the mechanisms of action, the efficacy, and the safety data of these novel agents. Biological products that are highly similar to reference biologic products whose patents have expired-also known as "biosimilars"-can be produced at lower cost with similar efficacy, and are also available for the treatment of IBD. We review the efficacy data for such agents as well.

Abstract
Biologic agents have revolutionized the care management of many life-threatening and debilitating diseases. As patents for older biologic therapies have begun to expire, the market has opened to copy versions of the originators - commonly referred to as biosimilars, follow-on biologic agents or subsequent-entry biologic agents - which are expected to gain a portion of the market, reduce health-care spending and increase treatment access worldwide. Importantly for patients with IBD, CT-P13 was the first biosimilar to infliximab that obtained regulatory approval by the European Medicines Agency in September 2013 and by the FDA in April 2016. In May 2016, SB2 was the second biosimilar to infliximab receiving marketing authorization in Europe. Currently, >20 other biosimilars to infliximab and adalimumab are in the development pipeline. Their similar-but-not-identical nature, and the concept of extrapolating efficacy and safety data from one therapeutic indication to another, seem to be confusing to physicians and cause concerns about the efficacy and safety of biosimilar products. A relevant debate is still ongoing in the field of IBD. This Review discusses the scientific principles underlying the biosimilar concept established in Europe and the USA, and discusses the current state of knowledge on biosimilar use in IBD.

Abstract
BACKGROUND AND AIM The aim of this survey was to find out the patients' perspectives concerning biosimilars. METHODS An online survey consisting of 14 questions was made available between November 2014 and October 2015. Only respondents who had heard of biosimilars were asked to respond the final twelve questions. RESULTS A total of 1181 patients responded. Of these, 38% had heard of biosimilars. The respondents worried about biosimilars' safety profile [47.0%], efficacy [40.3%], and molecular basis [35.0%]. Only 25.2% of the respondents had no concerns about biosimilars. Just over half [55.9%] of the respondents thought that the lower cost of the biosimilars should not come before their safety and efficacy. Only 12.5% of respondents felt that extrapolation made sense. The survey showed that 39.9% felt that patients should be systematically informed, and 26.7% felt that patient associations should be informed and able to give their opinions. It also revealed that 20.9% of the respondents would be against the idea of interchangeability if the patient was not aware; 65.7% of the respondents would want to know whether they were receiving the reference drug or the biosimilar, and have all necessary information in writing before the drug was administered. Only 31.0% of the respondents would be fully confident about biosimilars, even if they were prescribed and explained by the treating physician. CONCLUSIONS Most patients were not familiar with biosimilars, and those who were had doubts and concerns about the biosimilars' safety and efficacy. The patients wished to be informed and involved in decision-making concerning biosimilars.

Abstract
BACKGROUND Despite regulatory efforts to formalize guidance policies on biosimilars, there remains a need to educate healthcare stakeholders on the acknowledged definition of biosimilarity and the data that underpin it. OBJECTIVES The objectives of the study were to systematically collate published data for monoclonal antibodies and fusion protein biosimilars indicated for cancer, chronic inflammatory diseases, and other indications, and to explore differences in the type and weight (quantity and quality) of available evidence. METHODS MEDLINE, Embase, and ISI Web of Science were searched to September 2015. Conference proceedings (n = 17) were searched 2012 to July 2015. Included studies were categorized by originator, study type, and indication. To assess data strength and validity, risk of bias assessments were undertaken. RESULTS Across therapeutic areas, 43 named (marketed or proposed) biosimilars were identified for adalimumab, abciximab, bevacizumab, etanercept, infliximab, omalizumab, ranibizumab, rituximab, and trastuzumab originators. Infliximab CT-P13, SB2, and etanercept SB4 biosimilars have the greatest amount of published evidence of similarity with their originators, based on results of clinical studies involving larger numbers of patients or healthy subjects (N = 1405, 743, and 734, respectively). Published data were also retrieved for marketed intended copies of etanercept and rituximab. CONCLUSIONS This unbiased synthesis of the literature exposed significant differences in the extent of published evidence between molecules at preclinical, clinical, and post-marketing stages of development, providing clinicians and payers with a consolidated view of the available data and remaining gaps.

Abstract
INTRODUCTION CT-P13 is the first biosimilar to infliximab that has been approved for the same indications as its originator infliximab. No data are available on the effect of infliximab biosimilar on mucosal healing. The aim of this study was to evaluate the efficacy of CT-P13 induction therapy on mucosal healing in patients with ulcerative colitis [UC]. PATIENTS AND METHODS UC patients, who received CT-P13 therapy from its local introduction at three Hungarian and one Czech inflammatory bowel disease centres, were prospectively enrolled. Sigmoidoscopy was performed after the end of the induction therapy at week 14. Mucosal healing was defined as Mayo endoscopic subscore 0 or 1. Complete mucosal healing was defined as Mayo endoscopic subscore 0. Trough level of CT-P13 was measured at week 14. RESULTS Sixty-three UC patients who underwent CT-P13 induction therapy were enrolled in the study. Indication for the therapy was acute, severe flare up and chronic, refractory activity in 24 and 39 patients, respectively. Cumulative clinical response and steroid-free remission at week 14 were achieved in 82.5% and 47.6% of the patients, respectively. Sigmoidoscopy revealed steroid-free mucosal healing in 47.6% of the patients, and complete mucosal healing was present in 27%. Mayo endoscopic subscore decreased significantly at week 14 compared to baseline. Trough levels of infliximab correlated with mucosal healing. CONCLUSION This is, to our knowledge, the first study examining the efficacy of CT-P13 induction therapy on mucosal healing in UC. The results indicate that mucosal healing is achieved in two-thirds of UC patients by the end of the induction treatment with CT-P13.

Abstract
Aim In 2006, Omnitrope (by Sandoz) was the first approved biosimilar in Europe. To date, 21 biosimilars for seven different biologics are on the market. The present study compared the clinical trials undertaken to obtain market authorization. Methods We summarized the findings of a comprehensive review of all clinical trials up to market authorization of approved biosimilars, using the European public assessment reports (EPARs) published by the European Medicines Agency (EMA). The features compared were, among others, the number of patients enrolled, the number of trials, the types of trial design, choice of endpoints and equivalence margins for pharmacokinetic (PK)/pharmacodynamic (PD) and phase III trials. Results The variability between the clinical development strategies is high. Some differences are explainable by the characteristics of the product; if, for example, the PD marker can be assumed to predict the clinical outcome, no efficacy trials might be necessary. However, even for products with the same reference product, the sample size, endpoints and statistical models are not always the same. Conclusions There seems to be flexibility for sponsors regarding the decision as to how best to prove biosimilarity.

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
INTRODUCTION Crohn's disease (CD) and ulcerative colitis (UC) are chronic disabling conditions. Monoclonal antibody therapy directed against tumor necrosis factor-alpha (anti-TNF) has revolutionized the care of patients with inflammatory bowel disease (IBD). AREAS COVERED Considerations before starting anti-TNF therapy are highlighted: the best time to start with anti-TNF therapy, either alone or in combination with an immunomodulator, the choice of an anti-TNF agent and the contra-indications to anti-TNF therapy. Primary nonresponse and secondary loss of response are discussed. De-escalating therapy, the role of therapeutic drug monitoring and the use of biosimilars, are handled. Finally, the future directions of anti-TNF therapy are emphasized. EXPERT OPINION Anti-TNF therapy remains the cornerstone in the treatment of IBD. When initiating long-term therapy, safety and cost issues are of great importance. The therapeutic armamentarium in the treatment of IBD is rapidly growing. Therefore, the challenge is to optimize the use and refine the exact position of anti-TNF therapy in the near future, with personalized medicine as the ultimate goal.

Abstract
OBJECTIVE The cross-immunogenicity of the recently approved infliximab-biosimilar Remsima (CT-P13) with the originator drug Remicade is still unknown. DESIGN Sera of patients with IBD with or without measurable anti-Remicade antibodies to infliximab (ATI) were tested for their cross-reactivity to two batches of Remsima. Experiments were repeated after deglycosylation of Remicade/Remsima, IgG purification, excipients' dialysis and monomer purification by size exclusion chromatography. Anti-Remicade antibodies were tested for their functional inhibition of TNF-α binding by Remsima/Remicade by competition assay. Cross-reactivity of anti-adalimumab antibodies with Remicade/Remsima was also investigated. RESULTS 125 patients' and controls' sera were tested (median age 31 years, IQR 24.5-39.5). All 56 anti-Remicade ATI-negative controls (14 healthy individuals, 42 patients with IBD) were also negative for anti-Remsima ATI. All 69 positive anti-Remicade IBD sera were cross-reactive with Remsima. ATI titres against Remicade or Remsima were strongly correlated (r values between 0.92 and 0.99, p<0.001 for all experiments, Spearman's correlation test). The background ELISA signal for Remsima was slightly higher compared with Remicade in negative controls (1.25±0.6 µg/mL vs 0.76±0.5 µg/mL, respectively, p<0.001), and persisted after deglycosylation, dialysis or protein size filtration, but abolished by IgG purification and significantly diminished by monomer purification. Anti-Remicade ATIs of patients with IBD (n=10) exerted similar functional inhibition on Remsima or Remicade TNF-α binding capacity (p=NS for all inhibition curve points). Antibodies-to-adalimumab in adalimumab-treated patients with IBD (n=7) did not cross-react with either Remicade or Remsima. CONCLUSIONS Anti-Remicade antibodies in patients with IBD recognise and functionally inhibit Remsima to a similar degree, suggesting similar immunogenicity and shared immunodominant epitopes on these two infliximab agents. In contrast, anti-adalimumab antibodies do not cross-react with Remsima or Remicade.

Abstract
Many reference biological therapies have now reached or are near to patent expiry, and therefore a number of biosimilars have been or will be developed. The term biosimilar can be defined as a biotherapeutic product that is similar in efficacy, safety and quality to the licensed reference product. Biosimilars may lead to a reduced price and significant cost savings for the health community and hopefully more patients globally will have easier access to biological therapy when indicated. CT-P13, which is a TNF-alfa inhibitor, is the first monoclonal antibody biosimilar being used in clinical practice. The drug is approved for all indications as an innovator product although clinical efficacy has only been demonstrated in rheumatic diseases. Until now the number of patients with inflammatory bowel disease (IBD) treated with CT-P13 is confined, but experience is continuously growing. Based on current data, CT-P13 seems to be efficacious and generally well tolerated in IBD especially in patients who are naïve to biological therapy. Knowledge with regard to interchangeability between CT-P13 and the originator infliximab is however, still rather sparse and more data are desired. Immunogenicity and long-term safety related to CT-P13 are other areas of great importance and good and reliable postmarketing pharmacovigilance is therefore required in the coming years.

Abstract
OBJECTIVES The cost of medical care for Crohn's disease (CD) and comorbidities in the era of biologics is unclear. We examined insurance claims data from US health plans to understand this relationship. METHODS Longitudinal CD patient data and reimbursement information from 11 health plans engaged with Accordant Health Services between 2011 and 2013 were analyzed. The analysis considered data for all CD patients and for the patient subgroup ≤20 years and >20 years of age. Descriptive statistics measured the mean health-plan paid costs per patient, the relative cost contribution of anti-tumor necrosis factor (TNF) agents, and health care costs for 31 specific comorbid conditions among CD patients. RESULTS Overall, there were 5,090 CD patients (57% women) of which 587 CD patients were ≤20 years of age. The mean health-plan paid cost per member per year was $18,637 (s.d. $32,023) for all CD patients, $22,796 (s.d. $ 41,905) for CD patients ≤20 years, and $18,095 (s.d. $30,065) for patients >20 years of age. Twenty-eight percent of CD patients accounted for 80% of total costs. No differences were found in costs based on gender. Increased health-plan paid costs were significantly correlated with the number of comorbid conditions across all ages. Pharmacy utilization costs account for nearly one-half (45.5%) of the total CD-attributable costs, exceeding inpatient care costs. Anti-TNF agents alone comprised nearly one-third (29.5%) of total costs. Aside from anti-TNF costs, other major categories of expense were as follows: inpatient 23.1%, outpatient hospital setting 15.7%, and MD office 8.2%. CONCLUSIONS Total health-care costs in CD exceed previous estimates, with the majority of costs being allocated to a relatively small subgroup of patients. Pharmacy utilization costs, owing to anti-TNF use, result in increasing total health-care costs and currently exceed costs for inpatient care. Pragmatic strategies to encourage gastroenterologists in the best clinical practice of optimizing anti-TNF use-in particular for younger age patients and those with multiple comorbidities-are necessary to reduce avoidable pharmacy utilization and inpatient care costs.

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
Inflammatory bowel disease (IBD) is a disorder of unknown aetiology that provokes chronic inflammation of the gastrointestinal tract. Anti-tumor necrosis factor drugs have represented a major advance in the treatment of IBD patients in the last few years and also have a good safety profile. Nevertheless, these treatments are not effective in all patients and, in initial responders, there can be a loss of response in the long-term. Consequently, new treatments are needed for IBD, aimed at distinct therapeutic targets. In the last few years, new molecules have been incorporated into the therapeutic armamentarium of IBD patients. Golimumab is an anti-tumor necrosis factor monoclonal antibody with demonstrated effectiveness in the treatment of ulcerative colitis. The use of CT-P13 (biosimilar infliximab) has been approved in Europe for the same indications as the original infliximab. More recently, vedolizumab, an anti-α4β7 integrin monoclonal antibody, has been approved for the treatment of Crohn's disease and ulcerative colitis. A large number of molecules are currently under development, some of which will, in the future, broaden the therapeutic options available in the treatment of IBD patients. Finally, in the next few years, studies should aim to identify factors predictive of response to the distinct biological agents for IBD in order to allow personalized selection of the best therapeutic alternative for each patient.

Abstract
BACKGROUND AND AIM The biosimilar of infliximab, CT-P13, has recently been shown to be equivalent to infliximab in both efficacy and safety in the treatment of rheumatologic diseases. However, no data are available with respect to the drug's efficacy in patients with inflammatory bowel disease (IBD). We aimed to assess the efficacy and safety of CT-P13 in IBD patients METHODS This was a retrospective multicenter study including both anti-tumor necrosis factor (TNF) naïve patients and patients who switched from the biologic originator to CT-P13. RESULTS In anti-TNF naïve Crohn's disease (CD) patients (n = 32), clinical response and remission rates were 90.6% and 68.8% at week 2, 90.6% and 84.4% at week 8, 95.5% and 77.3% at week 30, and 87.5% and 75.0% at week 54, respectively. In anti-TNF naïve ulcerative colitis (UC) patients (n = 42), clinical response and remission rates were 76.2% and 19.0% at week 2, 81.0% and 38.1% at week 8, 91.3% and 47.8% at week 30, and 100% and 50.0% at week 54, respectively, while mucosal healing rates were 58.3% at week 8, 66.7% at week 30, and 66.7% at week 54. The efficacy of CT-P13 was maintained in 92.6% (25/27) of CD patients and in 66.7% (6/9) of UC patients after switching from its originator. Adverse events related to CT-P13 occurred in 11.8% of UC patients. CONCLUSIONS CT-P13 appears to have comparable efficacy, safety, and interchangeability with its originator in the treatment of IBD. Further prospective studies with long-term follow-up periods will be needed to confirm the biosimilarity of CT-P13.

Abstract
BACKGROUND Anti-tumour necrosis factor (anti-TNF) monoclonal antibodies have shown efficacy in inflammatory bowel diseases (IBD). As these therapies lose patent protection, biosimilar versions of the originator products are being developed, such as the infliximab biosimilar CT-P13; however, some uncertainty exists regarding their pharmacology in IBD. AIM To review the literature on anti-TNF biosimilars focusing on pharmacokinetics, pharmacodynamic properties and comparative effectiveness, related to their use in IBD. METHODS A PubMed literature search was performed using the following terms individually or in combination: 'biosimilars,' 'CT-P13,' 'Crohn's disease,' 'inflammatory bowel disease,' 'ulcerative colitis,' 'anti-TNFα therapy,' 'infliximab,' 'adalimumab,' 'pharmacokinetics,' 'immunogenicity.' RESULTS Bioequivalence of CT-P13 and infliximab was shown in ankylosing spondylitis (AS) and therapeutic equivalence in rheumatoid arthritis (RA). Preliminary results of CT-P13 in IBD come from small post-marketing registries and case series with a relatively short-term follow-up period and suggest comparable efficacy and safety to infliximab. Inter- and intra-individual differences in exposure and response are well known for the original molecules but dosing regimens and concomitant medications are different for RA compared to IBD, limiting the ability to translate some of the pharmacology data in RA to IBD. Uncertainty exists about cross-reactivity of anti-drug antibodies and whether similar exposure-response relationships will be observed for biosimilars and efficacy thresholds for therapeutic drug monitoring can be used interchangeably. CONCLUSIONS It is likely that biosimilars will be widely used for the treatment of IBD due to their cost savings and comparable efficacy. Nevertheless, robust post-marketing studies and pharmacovigilance are warranted in the coming years.

Abstract
BACKGROUND This article presents the design of clinical trials for the development of biosimilars in the European Union and the United States, with special focus on inflammatory diseases. METHODS All information available in PubMed and the Internet relating to the clinical development of biosimilars in inflammatory rheumatic conditions (e.g. rheumatoid arthritis, psoriasis, psoriatic arthritis and ankylosing spondylitis) was collated. The European Medicines Agency (EMA) and US Food and Drug Administration (FDA) websites were screened for guidelines on biosimilars. RESULTS More than 10 years ago the EMA began to publish guidelines for the development of biosimilars and several biosimilars have now been approved. In the USA the FDA has published guidance for the nonclinical and clinical development of biosimilars but until early 2015 no biosimilar had been approved. CONCLUSION Clinical trials aim to resolve uncertainties that may remain following nonclinical development regarding the similarity of the proposed biosimilar with the reference product. Pharmacokinetic and pharmacodynamic studies are essential for early clinical development and further phase 3 clinical studies. Factors to be considered in the clinical process include study population, design, endpoints, sample size, duration and analytical methods.

Abstract
Six biologic agents are currently approved for the treatment of IBD: four anti-TNF agents (infliximab, adalimumab, golimumab and certolizumab pegol) and two anti-integrin agents (natalizumab and vedolizumab). In Crohn's disease and ulcerative colitis refractory to standard medications, treatment choice among available biologic agents can be challenging. Several parameters should be taken into account to help physicians through the decision-making process, including the comparative effectiveness and long-term safety profile, availability and labelling in the prescriber's country, international guidelines, and cost, as well as patient preferences (such as the route of administration). Herein, we provide practical insights on the use of biologic agents in IBD. The results of head-to-head trials between biologic agents are eagerly awaited to guide decision-making regarding the choice of first-line biologic agents and to determine whether switching within the same drug class or swapping (switching out of the drug class) is preferable after primary or secondary loss of response to the first biologic agent. In the near future, treatment algorithms might evolve with the launch of new drugs (such as ustekinumab, tofacitinib and etrolizumab) and the increased use of biosimilars.

Abstract
Although corticosteroids are an effective treatment for induction of remission in inflammatory bowel disease (IBD), many patients are dependent on or refractory to corticosteroids. This review is based on scrutinizing current literature with emphasis on randomized controlled trials, meta-analyses, and Cochrane reviews on the management of IBD refractory to corticosteroids. Based on this evidence, we propose algorithms and optimization strategies for use of immunomodulator and biologic therapy in IBD refractory to corticosteroids.

Abstract
PURPOSE OF REVIEW The goal is to review the most recent literature about biosimilars in inflammatory bowel disease (IBD), with emphasis on controversial regulatory issues. RECENT FINDINGS Although biosimilars have been in use in Europe since 2005, the recent approval of CT-P13 (Remsima, Inflectra), a biosimilar of the reference infliximab (Remicade), by the European Medicines Agency (EMA) and several regulatory agencies has become a widely discussed topic in IBD, rheumatology, and other areas. Biologics are the main drivers of cost in current IBD units, and biosimilars can reduce prices thus increasing the availability of this type of treatment. The guidelines for evaluation of biosimilars are considerably different from those of the reference biologics, regulatory agencies relying on detailed in-vitro studies for defining 'high similarity', and requiring many fewer clinical data. 'High similarity' is considered sufficient for clinical trials, as the new molecule is demonstrated so structurally similar to the reference one that no significant difference in efficacy or safety is expected. Two trials in ankylosing spondylitis and rheumatoid arthritis gave no evidence of real difference and provided the required pharmacokinetic and PD data. The main controversy remains in the 'extrapolation' of indications, accepted by EMA but not by Health Canada. Position statements from several scientific societies and some expert's reviews have expressed concerns to the concept of extrapolation without direct IBD clinical evidence, whereas EMA experts have published detailed reviews supporting extrapolation. SUMMARY Biosimilars in IBD are here to stay. New data are awaited to settle the controversy of extrapolation, but only the complex behavior of markets will show whether biosimilars fuel competition and extend access to biologics with significant cuts in drug costs.

Abstract
Musculoskeletal manifestations are the most common extraintestinal manifestations in inflammatory bowel diseases. Some appendicular manifestations are independent of gut inflammation and are treated with standard anti-inflammatory strategies. On the other hand, axial involvement is linked to gut inflammatory activity; hence, there is a considerable amount of treatment overlap. Biological therapies have revolutionized management of inflammatory bowel diseases as well as of associated articular manifestations. Newer mechanisms driving gut associated arthropathy have surfaced in the past decade and have enhanced our interests in novel treatment targets. Introduction of biosimilar molecules is expected in the US market in the near future and will provide an opportunity for considerable cost savings on healthcare. A multidisciplinary approach involving a gastroenterologist, rheumatologist, and physical therapist is ideal for these patients.

Abstract
Biological agents for inflammatory bowel diseases (IBD) targeting tumor necrosis factor (TNF) have changed the way to treat IBD refractory to standard medications and allowed us to reach new therapeutic goals such as mucosal healing and deep remission. A better understanding of the components of the pathological processes that are a hallmark of IBD has led to the development of a new family of biological agents in Crohn's disease and ulcerative colitis. Biosimilars, which are copy versions of currently licensed biological agents, will be soon available. The biosimilar of infliximab is as effective and as safe as its originator in rheumatologic conditions, while a new anti-TNF agent, namely golimumab, has been recently approved for refractory ulcerative colitis. Beyond TNF blockers, anti-adhesion molecules appear to be a potent drug class for IBD. Vedolizumab was recently approved for both Crohn's disease and ulcerative colitis. Numerous other compounds are in the pipeline. Ustekinumab looks very promising for Crohn's disease. Smad7 antisense oligonucleotide might enrich our armamentarium if preliminary data are confirmed in upcoming clinical trials. Herein, we review the efficacy and safety of new and emerging biological agents that are currently investigated in IBD clinical trials.

Abstract
Biologics have revolutionized several areas of medical therapeutics, and dozens of them are used by millions of patients. Monoclonal antibodies are only one type of biologics, but more than 900 are now in different phases of development. These drugs are complex to make and not cheap. The market is constantly increasing, and several biosimilars (copies of biologics) are being used, while many are still waiting to become available to the public. Biosimilars are more complex than generics, and regulatory agencies have very stringent criteria for approval. In the IBD field, the biosimilar infliximab (Inflectra®, Remsima®) has been recently approved by the EMA, but not by Canadian authorities. The EMA has considered that 'high similarity' in preclinical studies together with clinical data from two trials in ankylosing spondylitis and rheumatoid arthritis warrant the 'extrapolation' for all approved indications for original infliximab (Remicade®), specifically Crohn's disease and ulcerative colitis. Canadian authorities have not accepted extrapolation, based on differences in glycosylation (fucosylation) that could be related to properties important in Crohn's disease. Most scientific societies do support the idea of asking for specific clinical trials before approval, although they acknowledge that following EMA, FDA, and WHO guidelines warrant safe products. Practical issues such as interchangeability and substitution remain unsolved, and it is very likely that there will be different solutions at the national level. Pharmacovigilance plans will be key for obtaining reliable data. Biosimilars are not better drugs, but can be clearly cheaper and may facilitate access to new treatments in many populations.

Abstract
A biosimilar is a copy of an approved biological medicine whose patent protections have expired. Biosimilars of antibodies to tumour necrosis factor α (TNFα) are becoming important in the treatment of inflammatory bowel diseases (IBD). The first one introduced commercially is an infliximab biosimilar. The aim of this study was to provide an overview of anti-TNFα biosimilars. The literature on biosimilars of monoclonal anti-TNFα antibodies was reviewed, including their manufacture and approval pathways, concerns about efficacy, safety, immunogenicity, extrapolation, switching and labelling. Previous experience with biosimilars of epoetin and other growth factors was also reviewed. The infliximab biosimilar CT-P13 was the first biosimilar monoclonal antibody registered for the treatment of IBD. The major advantage of biosimilars is the reduced cost of therapy. Concerns have arisen, however, about the efficacy and safety of CT-P13 in IBD, the extrapolation of results from rheumatologic trials to IBD and the free interchangeability of CT-P13 with infliximab. Experience with simple peptide biosimilars, such as epoetins and growth factors, has generally been positive, with these biosimilars having similar efficacy and safety as the original products, although immunogenicity remains a major concern. Upcoming postregistration studies will address concerns on biosimilars in IBD, including their efficacy, safety, immunogenicity, switching and interchangeability. Biosimilars active against the same epitopes, but with improved pharmacokinetic properties that enhance their efficacy and/or safety, may be the next stage in the development of biosimilars. Anti-TNFα biosimilars represent promising new treatment options for patients with IBD. However, data on their efficacy and safety in IBD are needed.

Abstract
A health care system is needed where care is based on the best available evidence and is delivered reliably, efficiently, and less expensively (best care at lower cost). In gastroenterology, anti-tumor necrosis factor agents represent the most effective medical therapeutic option for patients with moderate-to-severe inflammatory bowel disease (IBD), but are very expensive and account for nearly a quarter of the cost of IBD care, representing a major area of present and future impact in direct health care costs. The ImproveCareNow Network, consisting of over 55 pediatric IBD centers, seeks ways to improve the value of care in IBD, curtailing unnecessary costs and promoting better health outcomes through systematic and incremental quality improvement initiatives. This report summarizes the key evidence to facilitate the cost-effective use of anti-tumor necrosis factor agents for patients with IBD. Our review outlines the scientific rationale for initiating cost-reducing measures in anti-tumor necrosis factor use and focuses on 3 implementable strategies and 4 exploratory considerations through practical clinical guidelines, as supported by existing evidence. Implementable strategies can be readily integrated into today's daily practice, whereas exploratory considerations can guide research to support future implementation.
