Abstract
Background and aims Favourable clinical data were published on the efficacy of CT-P13, the first biosimilar of infliximab (IFX), in pediatric inflammatory bowel disease (IBD); however, few studies have compared the effect on endoscopic healing (EH) and drug retention rate between the IFX originator and CT-P13. Therefore, we aimed to compare EH and the drug retention rate between the IFX originator and CT-P13. Methods Children with Crohn's disease (CD) and ulcerative colitis (UC)/IBD-unclassified (IBD-U) at 22 medical centers were enrolled, with a retrospective review conducted at 1-year and last follow-up. Clinical remission, EH and drug retention rate were evaluated. Results We studied 416 pediatric patients with IBD: 77.4% had CD and 22.6% had UC/IBD-U. Among them, 255 (61.3%) received the IFX originator and 161 (38.7%) received CT-P13. No statistically significant differences were found between the IFX originator and CT-P13 in terms of corticosteroid-free remission and adverse events. At 1-year follow-up, EH rates were comparable between them (CD: P=0.902, UC: P=0.860). The estimated cumulative cessation rates were not significantly different between the two groups. In patients with CD, the drug retention rates were 66.1% in the IFX originator and 71.6% in the CT-P13 group at the maximum follow-up period (P >0.05). In patients with UC, the drug retention rates were 49.8% in the IFX originator and 56.3% in the CT-P13 group at the maximum follow-up period (P >0.05). Conclusions The IFX originator and CT-P13 demonstrated comparable therapeutic response including EH, clinical remission, drug retention rate and safety in pediatric IBD.

Abstract
BACKGROUND Pharmacokinetic non-inferiority of subcutaneous (SC) to intravenous (IV) CT-P13 maintenance therapy was demonstrated in a randomized trial (NCT02883452). This post hoc analysis evaluated longitudinal clinical outcomes with the two infliximab treatment strategies. METHODS Patients with Crohn's disease or ulcerative colitis received CT‑P13 IV loading doses (5 mg/kg; Week [W] 0 and W2) before randomization (1:1) to receive CT-P13 SC (body weight-based dosing every 2 weeks [Q2W]; W6-54; 'SC maintenance group') or CT‑P13 IV (5 mg/kg Q8W; W6-22) then CT-P13 SC (Q2W; W30-54; 'IV-to-SC switch group'). Paired W30/W54 patient-level data were analyzed. RESULTS Fifty-three (IV-to-SC switch) and fifty-nine (SC maintenance) patients were analyzed. Median trough serum CT-P13 concentrations were significantly higher at W54 versus W30 in the IV-to-SC switch group (20.4 versus 2.3 µg/mL; p < 0.00001), while remaining consistent in the SC maintenance group. Statistically significant improvements in pharmacokinetics, efficacy, fecal calprotectin levels, and quality of life were seen following switch to SC administration at W30 in the IV-to-SC switch group; safety findings were similar pre- and post-switch. CONCLUSION Formulation switching from IV to SC infliximab maintenance therapy was well tolerated and may provide additional clinical improvements. Findings require confirmation in larger prospective studies.

Abstract
Background: The infliximab biosimilar CT-P13 was approved in Thailand in 2015. Methods: This open-label, multicenter, post-marketing surveillance study evaluated the safety (events of special interest [ESIs]; primary end point) and effectiveness of 46 weeks of CT-P13 treatment according to routine practice in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), or psoriatic arthritis (PsA), with 1 year follow-up post-treatment. Results: 30 patients were enrolled (16 RA, 8 AS and 6 PsA). Infections were the most frequently reported study drug-related ESIs (2 RA and 2 AS). One patient with RA and one with PsA experienced infusion-related reactions. No cases of tuberculosis, malignancy (as expected, given 1 year follow-up), or drug-induced liver disease were reported. Disease activity improved across indications. Conclusion: CT-P13 was well tolerated and effective across indications.

Abstract
INTRODUCTION As of May 2023, 19 and 18 biosimilars have been approved for the treatment of rheumatoid arthritis (RA) by the European Medicines Agency (EMA) and United States Food and Drug Administration (US FDA) respectively. AREA COVERED Pharmacokinetic results of phase 1 studies of approved biosimilars were reviewed by systematic literature search. The impact of immunogenicity on the pharmacokinetic data and clinical response was assessed, and the potential benefit of monitoring serum concentrations of biologic drugs is discussed. The advantage of subcutaneous CT-P13 (an infliximab biosimilar) in clinical practice is reviewed. EXPERT OPINION Biosimilars are approved based on the totality of evidence including comparable physiochemical properties, PK / PD profiles, and clinical efficacy and safety to the originator. To utilize biosimilars more effectively, physicians should be aware of the utility of combination DMARD therapy to reduce immunogenicity and maintain efficacy and PK profile. PK monitoring, however, is not currently recommended in clinical practice. CT-P13 subcutaneous (SC) is the first SC infliximab used for treatment of RA patients. Based on data from clinical studies and the real world, SC-infliximab is an attractive therapeutic option compared to IV formulations of infliximab based on its efficacy, pharmacokinetics, patient-reported outcomes, and safety profile.

Abstract
BACKGROUND The objective of this non-interventional, observational prospective cohort study (CONNECT-IBD) was to assess the use of CT-P13 (Inflectra®) in the treatment of patients with Crohn's disease (CD) and ulcerative colitis (UC) in the context of treatment with reference infliximab (IFX; Remicade®). METHODS Patients (recruited April 2015 to October 2018) at 150 sites across 13 European countries were followed for up to 2 years. Primary outcomes were safety, population characteristics, and drug utilization patterns. Secondary outcomes included clinical assessment of disease activity. Data were analyzed descriptively. RESULTS Overall, 2543 patients (CD, n = 1676; UC, n = 867) were included. In the CT-P13 cohort (n = 1522), median disease duration was 63 (0-579) months and 30% of patients were IFX naïve; median duration of prior IFX treatment was 5 months. During the observation period, median duration of drug exposure was 14 (0-28) months. 41% of patients reported 912 all-causality treatment-emergent adverse events (TEAEs); 24% experienced treatment-related TEAEs. Most TEAEs were of mild-to-moderate severity. Treatment-emergent serious adverse events were reported by 17% of patients. CONCLUSION Safety information for CT-P13 in this large study was consistent with the known safety profile for IFX and did not alter the established benefit-risk profile of CT-P13.

Abstract
BACKGROUND This study evaluated the existence of anti-drug antibodies (ADAs) before and 52 weeks after switching from intravenous infliximab (IFX) to intravenous CT-P13 in patients with rheumatoid arthritis (RA). METHODS We performed a prospective observational study. Twenty-eight patients (7 males and 21 females) received intravenous CT-P13 after intravenous IFX, and the clinical data were collected from medical records. Rheumatoid factor (RF) and anti-CCP antibody were examined at baseline. At baseline and 52 weeks after the start of CT-P13 treatment, the Disease Activity Score based on the 28-joint count and the levels of C-reactive protein, matrix metalloproteinase-3, and ADA, as well as the erythrocyte sedimentation rate were evaluated. ADAs were measured using an enzyme-linked immunosorbent assay kit. RESULTS Seven (25%) and 6 (21.4%) cases were positive for ADAs at baseline and 52 weeks after, respectively. One case became newly positive for ADAs at week 52. Two of the ADA-positive cases became ADA-negative 52 weeks after. The ADA-positive group showed significantly higher RF values at baseline than the ADA-negative group (p = 0.03). No difference was observed between the ADA-positive group and the ADA-negative group regarding other clinical parameters. CONCLUSIONS The positive rate of ADAs did not increase after switching from intravenous IFX to intravenous CT-P13. Among the patients with ADAs, a high level of RF was observed at baseline.

Abstract
Based on extrapolation of similar clinical outcomes in rheumatoid arthritis to the originator infliximab (IFX) in randomized clinical trials, the first biosimilar antibody CT-P13 was approved for the treatment of psoriasis. To evaluate the safety, efficacy, and drug survival of CT-P13 for psoriasis in real-world clinical practice, prospective post-marketing surveillance was conducted in 165 Japanese psoriasis patients. During a 1-year follow-up period, adverse drug reactions (ADRs) occurred in 29 patients (17.6%). Infusion reaction was the most frequent ADR (6.7%), and mild pneumonia was reported as the only case of infection. Serious ADRs were reported in two patients (1.2%): acute cholecystitis and interstitial pneumonia. The interstitial pneumonia developed after a single infusion of CT-P13 and the patient died of respiratory failure. In naive patients to biologic therapy (n = 44), the Psoriasis Area Severity Index (PASI) decreased rapidly after the start of CT-P13 treatment, and response rate achieving an absolute PASI score <1 was 55% at 30 weeks. The response rate was high (78%) in patients with psoriatic arthritis, and 40% and 20% in those in plaque psoriasis and pustular psoriasis, respectively. Of patients switched from IFX to CT-P13 mainly for nonmedical reasons (n = 105), 57% had already reached PASI <1 by pretreatment with IFX and CT-P13 maintained this status. The incidence of ADRs in this patient group was low and the drug survival rate was as high as 74%, even at 1 year, which was significantly higher than that in the naïve patient group (47%). Patients switched from other biologics for medical reasons (n = 16) responded similarly to biologic-naïve patients, but drug survival was lower (24%). In conclusion, CT-P13 showed excellent effectiveness as a first-line therapy, no clinical difficulties in switching from IFX, and usefulness in patients who failed other biologics. CT-P13 could be a cost-effective alternative to IFX for the treatment of psoriasis.

We performed a multivariate logistic analysis to demonstrate the association between early infliximab trough levels and treatment outcomes of CT-P13 and originator infliximab. Methods Early serum infliximab trough levels and anti-drug antibody (ADA) levels were compared between CT-P13 (n=100) and originator infliximab (n=98) groups. Receiver operating characteristic (ROC) analysis and multivariate logistic analysis were conducted to identify optimal cutoffs of serum infliximab trough levels and predictive factors for clinical outcomes. Results The median infliximab trough levels were not different between CT-P13 and originator infliximab groups at week 6, week 14, and in median ADA levels at week 14, respectively. ROC analysis found an infliximab concentration threshold of 4.5 μg/mL at week 6 and 4.0 μg/mL at week 14 as the cutoff value with the highest accuracy for the prediction of clinical outcomes. Serum infliximab trough levels at weeks 6 and 14 predicted clinical remission at weeks 30 and 54, and endoscopic remission at week 54. The combinations of clinical remission or C-reactive protein normalization with an early infliximab trough level improved the prediction of long-term clinical or endoscopic remission. Conclusions A threshold in serum infliximab trough level at week 6 and week 14 was highly predictive for long-term clinical outcomes. There were no statistical differences in serum infliximab trough levels and ADA levels between CT-P13 and originator infliximab.

Abstract
BACKGROUND Intravenous [IV] infliximab is a well-established therapy for inflammatory bowel diseases [IBD] patients. A subcutaneous [SC] formulation of infliximab [CT-P13] has recently been shown to be as effective as IV infliximab after two doses of IV induction in a randomised trial, but there are no data to support elective switching of patients on maintenance IV infliximab therapy. We aimed to assess the effectiveness of an elective switching programme to SC CT-P13 in patients treated with IV infliximab. METHODS Patients on established maintenance IV infliximab, who switched to SC CT-P13, were included in this retrospective multicentre cohort study. Disease activity was monitored serially with the Harvey-Bradshaw Index [HBI] for Crohn's disease [CD] and the Simple Clinical Colitis Activity Index [SCCAI] for ulcerative colitis (UC) for up to 12 months at months 3, 6, and 12. Faecal calprotectin [FC] and C-reactive protein [CRP] were recorded at baseline and follow-up, if available. Infliximab trough levels were measured prior to switch and at months 3, 6, and 12 following switch. The primary outcome measure was treatment persistence at latest follow-up. Secondary outcome measures included infliximab pharmacokinetics [PK], safety, need for corticosteroid rescue therapy, and need for surgery. RESULTS We included 181 patients, of whom 115 [63.5%] had CD. The majority [72.4%] were on 8-weekly dosing of intravenous infliximab prior to switching, and more than half [59.1%] were on concomitant immunomodulatory therapy. The majority of patients (CD: 106, 92.2%; UC: 46, 76.7%; and IBD unclassified [IBD-U]: 5, 83.3%) were in clinical remission. Treatment persistence rate was high [n = 167, 92.3%] and only 14 patients [7.7%] stopped treatment during the follow-up period. There was no significant difference between baseline and repeat measurements at 3, 6, or 12 months for HBI, SCCAI, CRP, or FC. Of the total cohort, 25 patients (13.8%) had perianal CD. Of these, only two patients [8%] had worsening of perianal CD and required antibiotic therapy and further examination under anaesthesia [EUA]. Both these patients also switched back to intravenous infliximab. Median infliximab level increased from a baseline of 8.9 µg/dl [range 0.4-16] to 16.0 µg/dl [range 2.3-16, p <0.001] at 3 months. Serum levels stayed stable at 6 months [median 16 µg/dl, range 0.3-17.2] and 12 months [median 16 µg/dl, range 0.3-19.1, both p <0.001 compared with baseline]. Among the variables examined, only antibodies to infliximab [ATI] was associated with infliximab levels (odds ratio [OR] -13.369, 95% CI -15.405, -11.333, p <0.001]. A total of 14 patients [7.7%] developed ATI; of these, nine [64.3%] were on concomitant immunomodulatory therapy. Immunomodulatory therapy was not significantly associated with development of ATI [p = 0.15]. In a subset of patients receiving escalated IV infliximab dosing frequency prior to switching, no difference in treatment persistence was observed in patients receiving weekly versus alternate weekly SC CT-P13. Patient acceptance and satisfaction rates with SC CT-P13 were very high. CONCLUSIONS Among patients on IV infliximab maintenance therapy switched to SC CT-P13, we observed high treatment persistence rates and low rates of immunogenicity, with no change in clinical disease activity indices or biomarkers. Infliximab levels increased after switch to SC CT-P13, and only ATI was associated with serum infliximab levels. Patient acceptance and satisfaction rates were high with SC CT-P13.

Abstract
Background: Many pediatric inflammatory bowel disease (IBD) patients are now using biosimilars of anti-tumor necrosis factor-α (TNF-α), with increasing trends in recent years. This study reviewed all available data regarding the use of biosimilars in children with IBD. Methods: PubMed, Google Scholar, Scopus, and CENTRAL databases were searched through keywords; inflammatory bowel diseases, Crohn’s disease, ulcerative colitis, biosimilar and child were combined using “AND” and “OR.” Original research articles involving pediatric patients receiving one of the biosimilar medications based on the anti-TNF-α biologic drugs approved for pediatric IBD treatment, independently from efficacy and drug response, were included. Results: Nine studies were included in the evidence synthesis. CT-P13 was the biosimilar used in all studies. Four studies assessed the induction effectiveness of CT-P13. Clinical response and remission rates of biosimilar treatment were 86–90% and 67–68%, respectively, and they were not significantly different to the originator group. Five prospective studies on patients elected to switch from originator IFX to CT-P13 yielded similar results. Adverse events related to CT-P13 were mostly mild. The most frequently reported were upper respiratory tract infections. The switch from the originator had no significant impact on immunogenicity. Conclusion: The current review showed reported CT-P13 effectiveness as measured by clinical response and/or remission rates after induction or during maintenance and suggest that there is no significant difference with that of the originator IFX. Further studies are warranted, including clinical, and pharmacovigilance studies.

Abstract
BACKGROUND Though a single nonmedical switch from the originator infliximab (IFX) to a biosimilar is considered effective and safe for most patients with inflammatory bowel disease (IBD), very limited data are available on multiple successive switches. METHODS We performed a prospective multicenter cohort study of adult IBD patients who underwent 2 switches from the originator IFX to CT-P13 to SB2 (group 1), 1 switch from CT-P13 to SB2 (group 2), and 1 switch from the originator IFX to CT-P13 (group 3). Patients were assessed at 4 and 12 months since the most recent switch for remission using clinical (physician's assessment) and biochemical (C-reactive protein [CRP], and fecal calprotectin [FC]) measures. Patients discontinuing treatment for ineffectiveness or adverse events before month 12 were imputed as nonremitters. RESULTS One hundred seventy-six patients (Crohn's disease 71%, ulcerative colitis 27.8%, IBD unclassified 1.2%; group 1, 69; group 2, 80; group 3, 27) were included. At 12 months after the most recent switch 76.9% (40 of 52, group 1), 65.7% (46 of 70, group 2) and 76.9% (20 of 26, group 3) of patients were in clinical remission. Treatment persistence at 12 months was 85.0%, 87.0%, and 70.1%, respectively. There were no significant differences in the rate of clinical, CRP, FC remission, or treatment persistence at 12 months between the 3 groups. Infusion reactions occurred in 1.7% of patients (3/176), all in patients with antidrug antibodies from group 2. CONCLUSIONS Multiple successive switching and switching between biosimilars of IFX seemed to be effective and safe.

Abstract
BACKGROUND To compare the performances of Infliximab (IFX) biosimilar CT-P13 and SB2 in the treatment of Inflammatory Bowel Diseases (IBD) outpatients in Italy. RESEARCH DESIGN AND METHODS Three hundred and eighty IBD outpatients were retrospectively evaluated. The primary endpoint was to compare the two IFX biosimilars in terms of reaching and maintenance of remission at any timepoint. RESULTS 197 patients with Ulcerative Colitis (UC) and 183 patients with Crohn's Disease (CD) treated with CT-P13 or SB2 and having a median (IQR) follow-up of 12 (6-36) months were compared: 230 (60.5%) were naïve to anti-TNFα, 20 (5.26%) were switched from IFX originator or from IFX CT-P13 to IFX SB2. Clinical remission was achieved in 133 (67.5%) UC patients and in 164 (89.6%) CD patients (p < 0.000), with no differences between CT-P13 and SB2 in the rate of remission in UC (p = 0.667) and CD (p = 0.286). Clinical response, steroid-free remission, rate of surgery, mucosal healing (MH) in UC, switching from IFX originator or from other biosimilar, and safety were similar. Higher MH rate was obtained in CD patients treated with CT-P13 (p = 0.004). CONCLUSION This first comparative study found that both IFX biosimilars CT-P13 and SB2 are effective and safe in managing IBD outpatients.

Abstract
BACKGROUND In recent years, biological therapies have revolutionized the management of inflammatory bowel disease (IBD); however, they are expensive. The development of biosimilar products has allowed us to reduce healthcare costs and improve patients’ access to these treatments. Although various studies support the similarity between infliximab and its biosimilar CT-P13 in terms of efficacy and safety, there are unmet needs regarding research on these agents in the context of IBD.
AIM To analyze clinical response rates to CT-P13 and adverse events in IBD patients treated in real-life practice.
METHODS An observational, prospective, multicenter study of IBD patients treated with CT-P13 in clinical practice who were naïve to biological treatments or failed to respond to other anti-tumor necrosis factor drugs or had switched from infliximab originator was carried out. No diagnostic or follow-up interventions were conducted on patients outside usual clinical practice. The primary endpoints were clinical response rates and number of adverse events. The primary efficacy variable was the proportion of patients who were in clinical remission and/or had a clinical response at 3, 6, 9, and 12 mo.
RESULTS A total of 220 IBD patients treated with CT-P13 (Remsima®) were included in the study: 87 (40%) with ulcerative colitis and 133 (60%) with Crohn’s disease. Mean age of the patients was 41.47 (SD 15.74) years, and 58% were female. Nineteen (9%) patients started treatment with CT-P13 after switching from infliximab. Of the remaining 201 patients, 142 (65%) were naïve to biologic agents. At baseline, 68.6% (n = 138/201) of patients presented with active disease. After 12 mo of treatment, 14.8% (n = 12/81) presented with active disease, and 64.2% (n = 52/81) were in clinical remission without corticosteroids. After 3 mo, 75.5% (n = 115/152) had a clinical response or achieved clinical remission, which was sustained for 12 mo (85.2%; n = 69/81). There was a decrease in specific IBD indices at 3, 6, 9, and 12 mo (P < 0.001). A total of 34 adverse events were reported by 27 (12.3%) patients, 9 (26.5%) of which were serious.
CONCLUSION CT-P13 is an effective and safe infliximab biosimilar for the treatment of IBD in real-life practice and may be a valid and attractive alternative for the treatment of IBD.

Abstract
INTRODUCTION Management of Rheumatoid Arthritis (RA) has improved following the implementation of early intensive treat to target recommendations and the availability of different biologicals. Most experience is with TNF blockers, but challenges remain in the efficacy/safety balance, immunogenicity, and long-term drug survival as well as availability and affordability despite the introduction of biosimilars. AREA COVERED We provide an overview of the development of CT-P13 SC based on infliximab biosimilar CT-P13 IV. The one-year pivotal phase I/III trial in RA showed CT-P13 120 mg SC fixed dose to have favorable pharmacokinetics compared to CT-P13 IV classical weight adapted dosing, similar to lower anti-drug antibodies, similar safety and non-inferiority for efficacy at 6 months. EXPERT OPINION CT-P13 SC is an additional option in RA treatment and by extension for other inflammatory diseases as Inflammatory Bowel Disease. This new way of administration has the potential to improve long-term drug survival of infliximab, improve patient outcomes, and patient comfort.

Abstract
Background: Primary lack or secondary loss of response to therapy with infliximab is a significant problem. This study aimed to evaluate the response to treatment in patients with Crohn’s disease (CD) and ulcerative colitis (UC) achieving therapeutic and sub-therapeutic trough levels of biosimilar infliximab (CT-P13). Results: A total of 65 patients (32 with CD and 33 with UC) were recruited. The overall response rate in both CD and UC patients exceeded 80%. There were no significant differences in treatment response and CT-P13 levels for patients with CD or UC. We did not find significant differences in the percentage of patients achieving drug levels of 3 μg/mL at week 6, 10, or 12; a significant decrease was observed at week 14. Up to 55.5% of patients with CD and 64.3% of patients with UC with sub-therapeutic CT-P13 levels at week 14 primarily responded to treatment. Conclusions: Intermediate measurements of drug levels at weeks 10 and 12 did not capture any pronounced decrease in infliximab concentrations below therapeutic levels in either group, thus suggesting no clinical usefulness. A significant percentage of patients primarily responded to treatment despite sub-therapeutic drug levels after the induction phase.

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.

Abstract
OBJECTIVES The aim of this post-marketing surveillance (PMS) study is to evaluate the real-world safety and efficacy of CT-P13, the first biosimilar of infliximab (IFX). METHODS Japanese patients with rheumatoid arthritis were prospectively registered from November 2014 and followed up for 1 year. RESULTS Of 794 patients in the analysis set, 318 patients naïve to biological disease-modifying antirheumatic drugs (bDMARDs) showed an immediate decrease in Disease Activity Score in 28 joints with C-reactive protein (DAS28-CRP) and increased remission rate (DAS28-CRP < 2.6). In patients who switched from IFX to CT-P13 for non-medical reasons (n = 374), the low DAS28-CRP due to previous IFX treatment decreased further with continued CT-P13 therapy. As in naïve patients, patients who switched from other bDMARDs, mainly for medical reasons (n = 102), responded similarly to CT-P13. CT-P13 in this PMS and IFX in a previous PMS had similar adverse reaction profiles, although the incidence rate in naïve patients in this current PMS was lower due to earlier initiation of CT-P13 therapy. CONCLUSIONS CT-P13 showed excellent effectiveness as first-line therapy, no clinical difficulties in switching from IFX, and clinical improvement in patients who failed other bDMARDs. CT-P13 could be a cost-effective alternative to IFX in the treatment of rheumatoid arthritis.

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).

Abstract
The introduction of therapeutic monoclonal antibodies directed against tumor necrosis factor-α has revolutionized the treatment of inflammatory bowel disease (IBD) by improving quality of life, decreasing the frequency and length of hospital admissions, and reducing corticosteroid use. Nevertheless, biologics are very expensive, substantially contributing to the cost of care for patients with IBD. To reduce this cost and improve treatment access, biosimilars, which are therapeutic monoclonal antibodies (biologicals) similar to but not identical to the reference biologic, were introduced. Despite their potential benefits, the adoption and uptake of biosimilars have varied considerably across the USA and Europe. Here, we highlight the current biosimilar therapeutic landscape, discuss barriers to their use, and provide an overview of published studies evaluating the efficacy and safety of biosimilars in IBD.

Abstract
BACKGROUND AND AIM CT-P13, an infliximab (IFX) biosimilar, was approved for treatment of inflammatory bowel disease. However, no comparison with the originator IFX in this indication has been conducted in Japan where endemic levels of tuberculosis and hepatitis virus infection are not low. We evaluated the safety and efficacy in real-world data of CT-P13 and compared with originator IFX data in Japan. METHODS In a prospective post-marketing surveillance (PMS) study, patients who received CT-P13 in a 28-month period from January 2015 were followed up for 2 years. By conducting Japanese administrative database search (DBS) for the same period of PMS, data of the originator IFX including treatment persistence, tuberculosis incidence, and liver injury were analyzed retrospectively and compared with the corresponding PMS data of CT-P13. RESULTS CT-P13 persistence in PMS (n = 640) and IFX persistence in DBS (n = 4113) were almost similar between patients who switched from the originator and patients who continued on the originator, and also between the biologics-naïve patient groups. There were no differences in the incidences of tuberculosis and hepatic injury (Tuberculosis: 2 patients [0.31%] with CT-P13, 10 patients [0.24%] with the originator, P = 0.75; Hepatic injury: 18.5% with CT-P13, 15.4% with the originator, P = 0.22). Most of the patients with hepatic injury continued treatment in PMS and DBS at similar rates (80.8% vs 83.6%, P = 0.65). CONCLUSION The results of long-term PMS of CT-P13 compared with external reference data from an administrative database suggested that the biosimilar and its originator were comparably useful in real-world clinical practice.

Abstract
Objective To assess non-inferiority of s.c. to i.v. CT-P13 in RA. Methods Patients with active RA and inadequate response to MTX participated in this phase I/III double-blind study at 76 sites. Patients received CT-P13 i.v. 3 mg/kg [week (W) 0 and W2] before randomization (1:1) at W6 to CT-P13 s.c. via pre-filled syringe (PFS) 120 mg biweekly until W28, or CT-P13 i.v. 3 mg/kg every 8 weeks until W22. Randomization was stratified by country, W2 serum CRP and W6 body weight. From W30, all patients received CT-P13 s.c. In a usability sub-study, patients received CT-P13 s.c. via auto-injector (W46–54) then PFS (W56–64). The primary endpoint was change (decrease) from baseline in disease activity score in 28 joints (DAS28)-CRP at W22 (non-inferiority margin: −0.6). Results Of 357 patients enrolled, 343 were randomized to CT-P13 s.c. (n = 167) or CT-P13 i.v. (n = 176) at W6. The least-squares mean change (decrease) from baseline (standard error) in DAS28-CRP at W22 was 2.21 (0.22) for CT-P13 s.c. (n = 162) and 1.94 (0.21) for CT-P13 i.v. [n = 168; difference 0.27 (95% CI: 0.02, 0.52)], establishing non-inferiority. Efficacy findings were similar between arms at W54. Safety was similar between arms throughout: 92 (54.8%; CT-P13 s.c.) and 117 (66.9%; CT-P13 i.v.) patients experienced treatment-emergent adverse events (from W6). There were no treatment-related deaths or new safety findings. Usability was similar for CT-P13 s.c. via auto-injector or PFS. Conclusion CT-P13 s.c. was non-inferior to CT-P13 i.v. in active RA. The convenience of s.c. administration could benefit patients. Trial registration ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show/NCT03147248.

Abstract
The drug infliximab has been a key milestone in the treatment of inflammatory conditions such as Crohn's disease, ulcerative colitis, rheumatoid arthritis and the seronegative spondyloarthritides. Biosimilar drugs followed the originator, further improving access and diversity of therapy choice. Subcutaneous infliximab (CT-P13) holds potential for greater patient flexibility by self administration, reducing travel and hospital attendance for infusion, particularly relevant at a time of pandemic. We highlight the pharmacodynamic and pharmacokinetic basis of the subcutaneous device, clinical trials in rheumatology and gastroenterology and consider the safety and cost implications. Real-world switching data is required to confirm the efficacy data from clinical trials given the reduction in dosing flexibility compared with intravenous therapy.

Abstract
Reports of the prevalence of antibodies to infliximab (anti-drug antibodies, ADA) are inconsistent due in part to the various assay formats used to monitor immunogenicity in the clinic and under clinical trial settings. This study aimed to determine the frequency of ADA in patients with inflammatory bowel disease (IBD) during induction and maintenance therapy with biosimilar infliximab (CT-P13) using the ELISA (enzyme-linked immunosorbent assay) method. In this prospective single-center study, we analyzed the incidence of ADA and the relationship between the presence of ADA and the following variables: gender, type of disease, immunosuppressive therapy used, and duration of treatment. A total of 84 patients with IBD received CT-P13 and were followed up for an average of 7 months. We found ADA in 50% of the patients with undetectable levels of the drug. The percentage of persons with antibodies detected during induction treatment was 11.3% compared to 9.6% during maintenance therapy. The analysis showed no relationship between response to treatment and antibody titers (p = 0.381). The study showed a statistically significant relationship between undetectable levels of CT-P13 and the presence of ADA at week 6 of therapy (i.e., ADA were detected in all the patients with undetectable levels of CT-P13). Patients with IBD and undetectable levels of CT-P13 before administration of the third induction dose were at high risk of the presence of anti-drug antibodies as well as primary non-response.

Abstract
BACKGROUND & AIMS This study compared pharmacokinetics, symptomatic and endoscopic efficacy, safety, and immunogenicity of a subcutaneous formulation of the infliximab biosimilar CT-P13 (CT-P13 SC) vs intravenous CT-P13 (CT-P13 IV) in patients with inflammatory bowel disease (IBD). METHODS This randomized, multicenter, open-label, parallel-group, phase 1 study enrolled tumor necrosis factor inhibitor-naïve patients with active ulcerative colitis (total Mayo score 6-12 points with endoscopic subscore ≥2) or Crohn's disease (Crohn's Disease Activity Index 220-450 points) at 50 centers. After CT-P13 IV induction at Week (W) 0/W2, patients were randomized (1:1) to receive CT-P13 SC every 2 weeks (q2w) from W6 to W54 or CT-P13 IV every 8 weeks from W6 to W22. At W30, all patients receiving CT-P13 IV switched to CT-P13 SC q2w until W54. The primary endpoint was noninferiority of CT-P13 SC to CT-P13 IV for observed predose CT-P13 concentration at W22 (Ctrough,W22), concluded if the lower bound of the 2-sided 90% confidence interval (CI) for the ratio of geometric least-squares means exceeded 80%. RESULTS Overall, 66 and 65 patients were randomized to CT-P13 SC and CT-P13 IV, respectively. The primary endpoint of noninferiority was met with a geometric least-squares means ratio for Ctrough,W22 of 1154.17% (90% CI 786.37-1694.00; n = 59 [CT-P13 SC]; n = 57 [CT-P13 IV]). W30/W54 clinical remission rates were comparable between arms. Other efficacy, safety, and immunogenicity assessments were also broadly comparable between arms, including after switching. CONCLUSIONS The pharmacokinetic noninferiority of CT-P13 SC to CT-P13 IV, and the comparable efficacy, safety, and immunogenicity profiles, support the potential suitability of CT-P13 SC treatment in IBD.

Abstract
Objective The aim was to report results from PERSIST, a real-life, observational, prospective cohort study of CT-P13, an infliximab (IFX) biosimilar, for treatment of patients with RA, AS or PsA who were biologic naïve or switched from an IFX reference product (IFX-RP; Remicade). Methods Adult patients were recruited during usual care at 38 sites in Europe and Canada and enrolled by their physicians after meeting eligibility criteria according to the country-approved label for CT-P13. Primary outcomes were to determine drug utilization and treatment persistence and to assess safety. Patients were followed for up to 2 years. Data were analysed and reported descriptively. Results Of 351 patients enrolled, 334 were included in the analysis (RA, 40.4%; AS, 34.7%; PsA, 24.9%). The safety analysis set comprised all 328 patients treated with CT-P13. The majority (58.2%) of patients received CT-P13 monotherapy, most (72.6%) by dosing every 6 or 8 weeks. The mean treatment persistence was 449.2 days; 62.3% of patients completed 2 years of treatment. In all, 214 treatment-emergent adverse events (TEAEs) were reported in 38.4% of patients. Most TEAEs were of mild or moderate intensity; 13 were severe. The most commonly reported TEAEs were drug ineffective (9.5%) and infusion-related reactions (5.2%). The most frequently reported infection-related TEAEs were upper respiratory tract infections (3.0%), nasopharyngitis (2.1%) and bronchitis (1.5%). No patients experienced tuberculosis. Conclusion Drug utilization and treatment persistence with CT-P13 were consistent with historical reports of IFX-RP in this patient population. Safety findings did not identify new concerns for CT-P13 in the treatment of patients with RA, AS or PsA. Trial registration ClinicalTrials.gov: NCT02605642.

Abstract
BACKGROUND A subcutaneous (SC) formulation of infliximab biosimilar CT-P13 is approved in Europe for the treatment of adult patients with rheumatoid arthritis (RA). It may offer improved efficacy versus intravenous (IV) infliximab formulations. METHODS A network meta-regression was conducted using individual patient data from two randomised trials in patients with RA, which compared CT-P13 SC with CT-P13 IV, and CT-P13 IV with reference infliximab IV. In this analysis, CT-P13 SC was compared with CT-P13 IV, reference infliximab IV and pooled data for both reference infliximab IV and CT-P13 IV. Outcomes included changes from baseline in 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP), Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI), and rates of remission, low disease activity or clinically meaningful improvement in functional disability per Health Assessment Questionnaire-Disability Index (HAQ-DI). RESULTS The two studies enrolled 949 patients with RA; pooled data for 840 and 751 patients were evaluable at weeks 30 and 54, respectively. For the CT-P13 SC versus pooled IV treatment arm comparison, differences in changes from baseline in DAS28-CRP (- 0.578; 95% confidence interval [CI] - 0.831, - 0.325; p < 0.0001), CDAI (- 3.502; 95% CI - 5.715, - 1.289; p = 0.002) and SDAI (- 4.031; 95% CI - 6.385, - 1.677; p = 0.0008) scores at 30 weeks were statistically significant in favour of CT-P13 SC. From weeks 30 to 54, the magnitude of the differences increased and remained statistically significant in favour of CT-P13 SC. Similar results were observed for the comparison of CT-P13 SC with CT-P13 IV and with reference infliximab IV. Statistically significant differences at week 30 favoured CT-P13 SC over the pooled IV treatment arms for the proportions of patients achieving EULAR-CRP good response, American College of Rheumatology (ACR) 50 and ACR70 responses, DAS28-CRP-defined remission, low disease activity (DAS28-CRP, CDAI and SDAI criteria) and clinically meaningful HAQ-DI improvement. CONCLUSIONS CT-P13 SC was associated with greater improvements in DAS28-CRP, CDAI and SDAI scores and higher rates of clinical response, low disease activity and clinically meaningful improvement in functional disability, compared with CT-P13 IV and reference infliximab IV.

Abstract
The relatively high cost of anti-TNF agents and looming or actual expiry of patents for several biologics have led to the development of "highly similar" versions of the "originator" drugs called "biosimilars." The approval of biosimilars has been based on "extrapolation," whereby approval is granted in licensed indications for the reference product without the need for clinical trials. We discuss efficacy and safety data in support of biosimilar use from prospective studies, switching from originator biologic, impact on immunogenicity, pharmaco-economic, and practical considerations for clinicians.

Abstract
The biosimilar concept is now well established. Clinical data accumulated pre- and post-approval have supported biosimilar uptake, in turn stimulating competition in the biologics market and increasing patient access to biologics. Following technological advances, other innovative biologics, such as “biobetters” or “value-added medicines,” are now reaching the market. These innovative biologics differ from the reference product by offering additional clinical or non-clinical benefits. We discuss these innovative biologics with reference to CT-P13, initially available as an intravenous (IV) biosimilar of reference infliximab. A subcutaneous (SC) formulation, CT-P13 SC, has now been developed. Relative to CT-P13 IV, CT-P13 SC offers clinical benefits in terms of pharmacokinetics, with comparable efficacy, safety, and immunogenicity, as well as increased convenience for patients and reduced demands on healthcare system resources. As was once the case for biosimilars, nomenclature and regulatory pathways for innovative biologics require clarification to support their uptake and ultimately benefit patients.

Abstract
OBJECTIVES There are few comparative data for tumor necrosis factor inhibitors in patients with rheumatoid arthritis (RA). METHODS Historical data for reference product/biosimilar intravenous infliximab, or adalimumab and etanercept, were pooled and compared with phase 3 study results for a subcutaneous (SC) formulation of the infliximab biosimilar CT-P13, in a systematic review and meta-analysis (PROSPERO: CRD42019149621). RESULTS The authors identified 13 eligible controlled trials that randomized over 5400 participants to prespecified treatments of interest. Comparison with pooled historical data suggested a numerical advantage for CT-P13 SC over intravenous infliximab for almost every prespecified efficacy outcome evaluated, including Disease Activity Score in 28 joints (C-reactive protein/erythrocyte sedimentation rate), Clinical/Simplified Disease Activity Index scores, American College of Rheumatology responses, and multiple measures of disease remission and low disease activity; for the majority of outcomes, there was no overlap in 95% confidence intervals between groups. A numerical advantage for CT-P13 SC was also observed for safety outcomes (adverse events, infections, and discontinuations). Similar, but less marked, trends were observed for comparison with historical efficacy and safety data for adalimumab/etanercept. CONCLUSION CT-P13 SC offers an improved or similar benefit-to-harm ratio compared with infliximab (intravenous) and adalimumab/etanercept, for the treatment of moderate-to-severe RA.

Abstract
BACKGROUND Switching from IFX originator to CT-P13 is safe; however, little data on immunogenicity exists. RESEARCH DESIGN AND METHODS Consecutive IBD patients on IFX originator were switched to CT-P13 and followed-up for 12 months. Clinical activity, infliximab trough levels (ITLs), anti-drug antibodies (ATIs), and adverse events were recorded at predefined timepoints (baseline, second CT-P13 infusion, 6 and 12 months). The outcomes investigated were immunogenicity, pharmacokinetics, effectiveness and safety. RESULTS 119 patients were switched to CT-P13 after a median time with IFX of 5.8 years. No changes in mean ITLs were observed. ATIs were detected in 30 patients (25.2%): 14 before and 16 after switch. Mean persistent ATIs were significantly higher compared to mean transient ones (109.74 ng/mL ±84.70 vs 18.22 ng/mL ±11.37, p < 0.001), with significantly lower ITLs associated (mean 0.32 µg/mL ±0.6 vs 3.08 µg/mL ±3.22, p < 0.001). A significant decrease of patients in steroid-fee clinical remission was observed after the switch (p = 0.004), with subsequent improvement at 6 months (p = 0.005). Eighteen patients (15.1%) discontinued IFX, only 6 (5%) for loss of response. CONCLUSIONS Switching from infliximab originator to CT-P13 seems safe and effective, without differences in immunogenicity. A temporary reduction of clinical benefit after switching could be potentially explained by a 'nocebo-effect response'.

Abstract
BACKGROUND Whether therapeutic drug monitoring (TDM) of infliximab should be implemented in daily practice is an ongoing controversy. AIMS To assess the real-world use of TDM in an observational multicentre cohort study with consecutive patients with inflammatory bowel disease (IBD) treated with CT-P13. METHODS Between September 2015 and December 2016, 364 patients with IBD were treated with CT-P13 in 13 gastroenterology departments and were followed up for 54 weeks. Disease activity, CT-P13 trough concentration and anti-CT-P13 antibody (ACA) were recorded. RESULTS Steroid-free clinical remission rates at week 54 were 67.0% and 56.4% in patients with CD and UC, respectively. CT-P13 trough concentrations were measured in 70.7% of the patients. The mean CT-P13 trough concentration was 4.2±4.3μg/mL. The presence of ACA was observed in 53 (15.9%) patients. CT-P13 trough concentration was collected in a proactive approach in 62.8% of cases and in a reactive approach in 37.2%. Among patients who submitted to TDM, CT-P13 therapy was optimized in 88.7% of the reactive group and in 22.5% of the proactive group (P<0.001). CONCLUSION In a real-world cohort of patients with IBD treated with CT-P13, more than two-thirds of the patients underwent TDM. CT-P13 optimization was much less common in the proactive approach than in the reactive approach.

Abstract
INTRODUCTION Biologic drugs have significantly improved the treatment of ulcerative colitis (UC) and Crohn's disease (CD). However, the availability of these drugs is limited by their high cost. Infliximab was the first biologic to be approved for inflammatory bowel diseases (IBD). After its patent expired other manufactures developed biosimilar versions, among which CT-P13, and licensed them thorough an expedite process. AREAS COVERED The aim of this review is to summarize the available evidence on CT-P13 use in IBD, with particular interest in the phase II trials of a subcutaneous version of CT-P13. EXPERT OPINION Biosimilars, such as CT-P13, are an important resource for health-care systems. Although CT-P13 approval in IBD was based on extrapolation, subsequent studies confirmed its clinical equivalence to originator infliximab. A new subcutaneous formulation of CT-P13 showed promising results in phase I and II trials in both CD and UC. Clinical efficacy and safety were comparable and interestingly serum drug doses appeared to be more stable than conventional intravenous CT-P13. If these preliminary results will be confirmed, the first sub-cutaneous version of infliximab could soon be available for IBD.

Abstract
WHAT IS KNOWN AND OBJECTIVE Based on extrapolation, biosimilar infliximab (IFX) was approved to treat inflammatory bowel disease (IBD). The first studies in adults have shown similar efficacy and safety in comparison with reference drug. The aim of this review was to collect and evaluate all the literature data regarding the use of biosimilar IFX in paediatric IBD. METHODS This article reviewed efficacy, immunogenicity and safety profile of biosimilar IFX in IBD paediatric patients through a comprehensive search of the published literature. RESULTS AND DISCUSSION Eight papers were extracted and critically reviewed. Four paediatric studies (prospective, n = 3; retrospective, n = 1) assessed the induction efficacy of the biosimilar IFX. Clinical response and remission rates reported were 86%-90% and 67%-68%, respectively. No significant difference in clinical response and remission rates between the reference and biosimilar IFX groups was found at follow-up (range: 3-13 months). Similar findings were shown in the prospective studies (n = 4) conducted on patients elected to switch from reference IFX to its biosimilar. The most frequently reported adverse events (AEs) of biosimilar IFX were mild upper respiratory tract infections. Taking into account of all AEs coming from published data, biosimilar IFX seems to be as safe as its originator. Immunogenicity has not been significantly impacted by the switch from the reference drug. WHAT IS NEW AND CONCLUSION To date, treatment with (or switch to) biosimilar IFX in paediatric patients with IBD have been successful, without affecting efficacy, immunogenicity or safety. However, further studies are warranted, including clinical trials and pharmacovigilance studies.

Abstract
We evaluated the appropriateness of various equivalence margins for CT-P13, an infliximab biosimilar, in the PLANETRA clinical trial. The 95-95% method was used to independently determine an equivalence margin by pooling the historical clinical trials with original infliximab versus placebo, identified in a systematic literature search. The constancy assumption with the PLANETRA trial was assessed for each identified historical clinical trial to decide which study was scientifically justifiable to be pooled. A sensitivity analysis was performed for each study-pooling scenario. As a result, we identified two historical clinical trials that were deemed appropriate, whereas the PLANETRA trial pooled three additional studies to determine an equivalence margin, which was accepted by the United States Food and Drug Administration. However, those extra clinical trials did not meet the constancy assumption in baseline characteristics, methotrexate dose, and efficacy assessment time. The clinically more appropriate equivalence margin was 5.7 percentage points, which was much narrower than the 12 percentage points applied in the approval of CT-P13. In conclusion, the equivalence claim for CT-P13 to original infliximab in patients with rheumatoid arthritis did not appear to be supported when the constancy assumption was strictly assessed. The equivalence margin for biosimilars could be determined more conservatively.

Abstract
The introduction of anti-TNFs, such as infliximab (IFX), has revolutionized the treatment of immune-mediated inflammatory diseases. Anti-TNF agents have shown outstanding efficacy and long-term improvement of clinical outcomes, but the cost has been relatively high. Out of this concern, several 'biosimilar' drugs of anti-TNF agents have been developed. CT-P13, the first biosimilar of reference IFX, was approved by the European Medicines Agency and licensed by the US FDA for use in all indications of IFX. This updated review summarizes all aspects of CT-P13, including pharmacology and pharmacokinetics, and evaluates its efficacy, safety and immunogenicity for all indications based on the results of the latest clinical trials as well as on real-world experiences.

Abstract
BACKGROUND The use of infliximab biosimilar CT-P13 has increased in patients with inflammatory bowel disease. Nevertheless, doubts about switching from infliximab originator to biosimilar still exist among patients and health care professionals. METHODS Our tertiary referral center underwent a mandatory switch from infliximab originator to CT-P13 in 2017. We investigated pharmacokinetics, efficacy, and safety of this switch. The primary endpoint was infliximab discontinuation within 6 months of switching. Secondary endpoints included loss of clinical remission, need for treatment optimization, adverse events, evolution of patient-reported outcome, C-reactive protein, infliximab trough levels, and antidrug-antibodies. RESULTS A total of 361 patients (54.0% male, 70.0% Crohn's disease, 55.6% in clinical remission) were enrolled. Infliximab discontinuation within 6 months was observed in 4%. Loss of clinical remission, adverse events, and antidrug-antibodies were identified in only 2.0%, 2.2%, and 1.1% of patients, respectively. C-reactive protein concentrations and infliximab trough levels remained stable. Independent factors associated with remission at 6 months were lower PRO2 at switch (HR 6.024; 95% CI, 4.878-8.000; P < 0.0001) and higher hemoglobin levels (HR 1.383; 95% CI, 1.044-2.299; P = 0.018). CONCLUSIONS Switching from infliximab originator to CT-P13 was not associated with an increased risk of treatment discontinuation, loss of clinical remission, or adverse events. No significant changes in infliximab trough levels or immunogenicity could be identified.

Abstract
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. French national IBD patients' association (Association François Aupetit) provided an information sheet on biosimilars. RESULTS 93 (67.0%) out of 138 and 82 (68.3%) out of 120 patients switched treatment. 114 (79.8%) had never heard about biosimilars. Paradoxically, having heard about biosimilars was associated with a poorer chance to switch (Odds Ratio OR [95% CI] = 0.13 [0.02-0.72]). On the contrary, the more satisfied about generics, the more patients accepted the switch (OR [95% CI] = 1.31 [1.01-1.69]). There were 1.47 (Relative Risk RR [95% CI] = 1.47 [1.07-2.01]) times more chance to agree to the switch if the interview modified the patient's opinion on biosimilars. CONCLUSION This study confirms that an organized information provided to the patient is a contributive way to enhance patient's acceptance of biosimilars in IBD.

Abstract
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. OBJECTIVE Because the appropriate dosing depends on accurate determination of drug levels and anti-drug antibodies, the ability of current Infliximab assays to measure the biosimilars and corresponding antibodies needs to be demonstrated. METHODS The correlation between Infliximab and the biosimilars measured with four different enzyme-linked immunosorbent assays for Infliximab detection was evaluated. Spiked serum samples were assayed with kits from (A) Immunodiagnostik/ALPCO Diagnostics, (B) R-Biopharm, (C) Theradiag and (D) Progenika Biopharma. The impact of various concentrations of antibodies to Infliximab on the quantification of biosimilars was also tested. RESULTS A good correlation of SB2, CT-P13 and reference Infliximab spiked serum samples was observed with the four assays. The observed bias between the original drug and biosimilars is clinically insignificant and less than the usual analytical variability observed with these methods. The quantification of the biosimilars and Infliximab was equally impacted in serums containing antibodies to Infliximab. The recovery of the drugs was inversely correlated with the concentration of anti-Infliximab antibodies, suggesting common immunodominant epitopes for SB2, CT-P13 and Infliximab. CONCLUSION The ability of these assays to properly quantify the biosimilars Renflexis® and Inflectra® has been demonstrated. The therapeutic drug monitoring required for Infliximab therapy can be adequately performed with the biosimilars using the kits currently in use or available in clinical laboratories.

Abstract
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. METHODS A literature search using PubMed and abstracts/posters from 3 major gastroenterology conferences from 2014 to 2018 was completed. Two individual reviewers extracted data from each relevant report and compiled it into evidence tables to facilitate descriptive analyses. Key randomized trial and observational study designs were critically assessed to contextualize data relevance. RESULTS A total of 49 reports (3 randomized controlled trials, 40 observational trials, and 1 case series) were included. Most studies revealed no efficacy, safety, or immunogenicity concerns with non-medical switch. Limitations of supporting data include a small number of randomized controlled trials; predominance of observational studies with varying outcome assessments and lack of appropriate controls; and scarcity of research on biosimilar switch long-term effects. CONCLUSIONS The majority of studies suggested non-medical switch is safe. However, clinicians and regulatory bodies should be aware of differences and limitations in study designs when making inferences about the risks and benefits of switching stable IBD patients to biosimilars.

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 Patients' perspectives after switching from infliximab to a biosimilar have yet to be assessed. AIM To assess patients' perspectives in a prospective manner after switching from infliximab to CT-P13. METHODS 113 consecutive patients with inflammatory bowel disease (IBD) on maintenance therapy with infliximab were switched to CT-P13. Patients' perspectives were assessed by questionnaires, including the Beliefs about Medicines Questionnaire (BMQ) and FACIT-F (questionnaire regarding fatigue), and patient-reported outcomes (IBD disability index) at the inclusion and after the fourth CT-P13 infusion. RESULTS After one year, the patients' perspectives did not change after the switch according to BMQ-general, BMQ-specific necessity and BMQ-specific concerns subscales. No difference was observed in the mean IBD-DI score, while a significant improvement in fatigue was observed according to the FACIT-F questionnaire. Patients' concerns were raised about the use of biosimilars and the risks of switching with a significant improvement after switching (65% vs. 42%, respectively, p = 0.01). Fourteen (12.4%) patients experienced loss of response to CT-P13, including 12 with restoration of steroid-free clinical remission after CT-P13 dose optimization. CONCLUSION Although some concerns were reported, no difference was observed in patients' perspectives after switching from infliximab to CT-P13.

Abstract
OBJECTIVE We aimed to evaluate the efficacy and safety of infliximab biosimilar, CT-P13, for patients with inflammatory bowel disease. METHODS We searched PubMed, Scopus, Ovid, and Web of Science for relevant clinical trials discussing CT-P31 administration for IBD patients either naïve to biological therapy or switched from IFX therapy. Data of the rates of clinical response, clinical remission, and adverse events were extracted and pooled in a random effect model meta-analysis using CMA version 2. RESULTS Thirty-two studies with a total of 3464 IBD patients treated with CT-P13 were identified. The pooled rates of clinical response among Crohn's disease (CD) and ulcerative colitis (UC) at 8-14 weeks were 0.81 (95% CI = 0.72 to 0.87) and 0.68 (95% CI = 0.63 to 0.72), respectively, and at 48-63 weeks were 0.69 (95% CI = 0.48 to 0.85) and 0.54 (95% CI = 0.45 to 0.63) respectively. After switching from IFX to CT-P13, the pooled rates of sustained clinical response among CD and UC at 30-32 weeks were 0.84 (95% CI = 0.57 to 0.96) and 0.96 (95% CI = 0.58 to 0.99), respectively, and at 48-63 weeks were 0.51 (95% CI = 0.22 to 0.79) and 0.83 (95% CI = 0.19 to 0.99) respectively. Moreover, adverse events were reported (CD = 0.10, 95% CI 0.04 to 0.22; UC = 0.18, 95% CI 0.05 to 0.15). CONCLUSION CT-P13 is effective and well tolerated in short and long-term periods. Switching to CT-P13 is recommended for the management of IBD.

Abstract
Biotechnologicals are an invaluable resource in the treatment of patients with inflammatory rheumatic diseases (IRD) non-responsive or intolerant to conventional therapies. However, they are the main driver for increase in direct costs and represent a significant economic burden to healthcare systems worldwide. Since biosimilars are similar and more affordable versions of previously licenced biotechnologicals, they are expected to contribute to healthcare system sustainability and reduce inequities in treatment access. The landmark approval of CT-P13 as the first infliximab biosimilar paved the way for new infliximab but also etanercept, adalimumab and rituximab biosimilars. In Europe, North America and some countries of Asia, development is strictly regulated and only those presenting a totality-of-evidence dossier with highly similar physicochemical, biological and clinical performances are endorsed by regulatory agencies as biosimilars. The current article addresses the importance of biosimilar medicines in the treatment of IRD, as well as their innovative development and regulatory pathways, clinical evidence of similarity and challenges that may undermine their widespread use and success.

Abstract
BACKGROUND AND AIM A biosimilar of infliximab, CT-P13 (Remsima®) has the potential to reduce treatment costs and enhance access to biological therapy for inflammatory bowel disease (IBD) patients. However, long-term clinical data on its use for IBD treatment are currently sparse. We aimed to investigate the long-term efficacy and safety of CT-P13 therapy in a large, real-life IBD cohort. METHODS A total of 368 IBD patients (227 with Crohn's disease [CD] and 141 with ulcerative colitis [UC]) treated with CT-P13 at 16 referral hospitals in Korea between July 2012 and December 2017 were retrospectively analyzed. RESULTS The cumulative retention rates at years 1, 3, and 5 were 86.1%, 68.5%, and 58.7% and 69.7%, 46.0%, and 26.7% in anti-tumor necrosis factor (TNF)-naïve CD and UC patients, respectively. The clinical response and remission rates at week 14 and at years 1, 3, and 5 were 94.3%, 92.7%, 76.8%, and 17.6% and 78.6%, 82.4%, 72.2%, and 17.6% in anti-TNF-naïve CD and 85.6%, 80.0%, 55.2%, and 6.7% and 42.6%, 59.8%, 44.2%, and 6.7% in anti-TNF-naïve UC patients, respectively. Among patients who switched from the biologic originator to CT-P13, the cumulative retention rates at years 1, 3, and 5 were 88.5%, 66.1%, and 44.8% in CD, and 73.9%, 42.5%, and 42.5% in UC patients, respectively. Significant improvements in disease activity scores were accompanied by marked reductions in inflammatory marker levels, and no unexpected adverse events including death or malignancy occurred during the study period. CONCLUSIONS Long-term treatment with CT-P13 is effective in inducing and maintaining disease improvement and is well-tolerated in patients with IBD. CT-P13 may be a promising treatment option for IBD.

Abstract
Introduction: CT-P13 was developed as an infliximab biosimilar in 2013. The primary structure of CT-P13 is identical to that of original infliximab and it has highly similar higher order structure, physiochemical characteristics, and biological properties. To date, data from real-life cohorts and randomized controlled trials show comparable clinical efficacy, safety and immunogenicity of biosimilar CT-P13, and the original reference medicinal Product (RMP). Areas covered: This article reviews the comparability of CT-P13 and the RMP and focuses on the emerging clinical trial and observational cohorts data on efficacy and safety of CT-P13 in inflammatory bowel disease (IBD) patients. The development of a subcutaneous formulation of Infliximab CT-P13 is also addressed. Expert opinion: There is a plethora of evidence to show CT-P13 is non-inferior to infliximab RMP in IBD and that a switch from RMP to this biosimilar is feasible and safe. However, interchangeability and multiple switches can still not be endorsed for introduction into clinical practice.

Abstract
BACKGROUND/AIMS An interim analysis of post-marketing surveillance of CT-P13, an infliximab biosimilar, was performed to evaluate its safety and efficacy in Japanese patients with inflammatory bowel disease. METHODS Patients were prospectively enrolled between November 2014 and March 2017, after the launch of CT-P13 in Japan, and case report forms of patients followed for at least 4 months were analyzed as of July 2018. RESULTS Of 523 patients in the analysis set, 372 remained on CT-P13 therapy, while 54 (20.2%) of 267 patients with Crohn's disease, and 97 (37.9%) of 256 patients with ulcerative colitis were withdrawn during follow-up. A total of 144 adverse drug reactions (ADRs) were reported in 106 patients (20.3%). Infusion reaction was the most frequent ADR observed in 49 patients (9.4%). Efficacy parameters decreased immediately after the start of treatment in naïve patients to anti-tumor necrosis factor-α antibody. In the patients switched from originator infliximab for nonmedical reasons, the decreased parameters due to proceeded treatment with the originator were maintained in low ranges, and the treatment continuation rate was high with low ADR incidence. In contrast, in patients switched for medical reasons such as adverse event or loss of response, the incidence of ADRs was high. However, the efficacy parameters were improved, and the treatment continuation rate was not significantly different from that of the naïve patient group. CONCLUSIONS In this interim analysis, CT-P13 was comparable to the originator infliximab with respect to ADRs and efficacy, and is therefore considered to be a cost-efficient interchangeable biosimilar for Japanese patients with inflammatory bowel disease.

Abstract
BACKGROUND Inflammatory bowel disease is treated with anti-TNF agents such as infliximab and its biosimilars, but use of biosimilars is limited due to perceived risks of adverse events. AIM To explore safety and effectiveness of switching from the infliximab originator to a first biosimilar. PATIENTS AND METHODS Clinical and biological outcomes were compared between 53 patients who switched from the infliximab originator to the biosimilar CT-P13 (Switched group) and 13 patients treated with CT-P13 from the beginning (Naïve group). Infliximab trough levels and antidrug antibodies were measured. RESULTS At enrolment, patients in the Switched group had a longer median duration of infliximab treatment than Naïve (4.0 vs. 0.6 years, p < 0.0001) but similar proportions of patients were in remission (77% and 62%, respectively). Infliximab discontinuation due to adverse events or loss of efficacy was less common in the Switched (26%) than Naïve group (62%, p = 0.017). Variables independently associated with time to discontinuation were disease activity (p < 0.0001) and immunomodulating treatment (p = 0.019) at enrolment. Trough levels and antidrug antibodies were similar between groups during observation. CONCLUSION This study confirms that switching from infliximab originator to a first biosimilar is safe and effective. Patients at highest risk of losing treatment efficacy are those with active disease, irrespective of the therapeutic switch.

Abstract
Objective: To assess the effectiveness and safety of biosimilar infliximab (CT-P13) in a real-life setting in adults with moderate-to-severe active Crohn’s disease (CD) or ulcerative colitis (UC). Methods: This multi-centre, observational cohort study was conducted at medical centres in Romania, Czech Republic, and Bulgaria. Effectiveness was measured using the Crohn’s Disease Activity Index (CDAI) for CD or partial Clinical Activity Index (pCAI) for UC. Quality-of-life (QoL) was measured using the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Safety was assessed according to treatment withdrawals and adverse events (AEs) monitoring. Analyses were performed in the safety population and were reported based on the observed case (OC) or last observation carried forward (LOCF) method. Results: Altogether, 85 patients with CD (n = 38) or UC (n = 47) received biosimilar infliximab for up to 30 weeks. Most patients (n = 68; 80.0%) had no prior exposure to infliximab. At the end of treatment, 65.8% (95% CI = 49.8–78.9) of CD patients and 55.3% (95% CI = 41.2–68.6) of UC patients showed a clinical response, and 47.4% (95% CI = 32.5–62.7) and 48.9% (95% CI = 35.3–62.8), respectively, were in remission. Statistically significant (p < 0.0001) improvements from baseline were observed in CDAI and pCAI scores (both LOCF). In the combined CD and UC population, SIBDQ was significantly improved (p < 0.0001) from baseline to end of treatment (OC). Two AEs (moderately severe infusion reactions) were judged by investigators to be definitely related to treatment, one of which led to treatment withdrawal. Conclusion: Results align with those of previous studies demonstrating the effectiveness and safety of biosimilar infliximab in CD and UC.

Abstract
BACKGROUND Several studies have reported positive efficacy outcomes for patients with inflammatory bowel disease treated with CT-P13, an infliximab biosimilar. Data from follow-up periods longer than 1 year are still scarce. Here, we assessed the long-term efficacy data, loss of response and safety after switching from infliximab to CT-P13 in patients with inflammatory bowel disease. METHODS This was a prospective single-center observational study involving patients with moderate-to-severe Crohn's disease and ulcerative colitis switched from infliximab to CT-P13 treatment and reviewed up to 24 months. Efficacy and loss of response were measured using the Harvey-Bradshaw (HB) index and partial Mayo score for patients with Crohn's disease and ulcerative colitis respectively. C-reactive protein, infliximab drug levels, adverse events and antidrug antibodies were also monitored throughout the study. RESULTS A total of 64 patients with Crohn's disease and 36 patients with ulcerative colitis were included. Most of them (72%) remained on CT-P13. Overall, 28% of patients discontinued the therapy due to loss of response, adverse events or long-lasting clinical remission. Remission at 18 and 24 months occurred in 69.9% and 68.5% of patients, respectively. Dose increase was performed in 22% of patients, with remission being reached in 60% of them. HB index, partial Mayo score, C-reactive protein and infliximab drug levels did not show significant changes. Serious adverse events were reported in 14% of patients. Overall, two patients developed low levels of antidrug antibodies. CONCLUSIONS Most of the patients switching from original infliximab were maintained on CT-P13 at 2 years of follow up with a good profile of efficacy and safety.
