Abstract
INTRODUCTION Biosimilar CT-P13 was approved with limited data from clinical trials compared to the originator infliximab in biologic-naïve patients with rheumatoid arthritis. Three prospective post-marketing surveillance studies have been conducted in Japanese biologic-naïve patients and switched patients from biologics including the originator infliximab. OBJECTIVE We performed an integrated analysis of final data from three post-marketing studies to provide long-term safety and efficacy data of CT-P13 in a real-world clinical setting. METHODS A total of 1816 patients consisting of 987 patients with rheumatoid arthritis, 342 patients with Crohn's disease, 322 patients with ulcerative colitis, and 165 patients with psoriasis were evaluated for safety. Efficacy was assessed in 1150 patients whose disease parameter values were serially collected. RESULTS Adverse drug reactions were reported in 24.2% of all patients. The incidence of adverse drug reactions differed by the prior treatment status with biologics: 30.5% in patients naïve to biologics, 17.0% in patients switched from the originator infliximab, and 33.5% in patients switched from other biologics. Infusion reactions were the most frequent adverse drug reactions (8.2%), and its incidence was significantly higher in patients with ulcerative colitis and an allergy history in a multivariable Cox regression analysis. Infection was the second most frequent (6.1%), but tuberculosis only occurred in four patients (0.2%). The incidence of infection was low in patients with Crohn's disease and psoriasis, and significant risk factors were an allergy history, comorbidities, and concomitant steroid use. Interstitial lung disease occurred in 16 patients (0.9%), including 11 patients with rheumatoid arthritis. With CT-P13 therapy, disease activity parameters decreased similarly in all four diseases, although long-term drug discontinuation rates because of inefficacy varied by disease. In naïve patients, the disease activity parameters decreased rapidly and the proportion of patients in remission increased. Patients switched from infliximab maintained lowered parameter levels with infliximab pretreatment. Decreases were also observed in patients switched from other biologics, but discontinuations were most often because of insufficient efficacy. CONCLUSIONS The integrated analysis of a large number of patients detected no new safety signals with long-term CT-P13 treatment. Efficacy in rheumatoid arthritis, psoriasis, Crohn's disease, and ulcerative colitis cases was confirmed in biologic-naïve patients and switched patients from the originator infliximab or other biologics.

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.

Real-world observational cohort study of treatment patterns and safety outcomes of infliximab biosimilar CT-P13 for the treatment of inflammatory bowel disease (CONNECT-IBD). Expert Opin Biol Ther 2023; 23:791-800. [PMID: 37038897 DOI: 10.1080/14712598.2023.2200883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 04/05/2023] [Indexed: 04/12/2023]
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.

BioDrugs 2022; 36:359-371.

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

Impact of Infliximab Biosimilar CT-P13 Dose and Infusion Interval on Real-World Drug Survival and Effectiveness in Patients with Ankylosing Spondylitis. J Clin Med 2021; 10:jcm10194568. [PMID: 34640586 PMCID: PMC8509762 DOI: 10.3390/jcm10194568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/16/2021] [Accepted: 09/24/2021] [Indexed: 11/28/2022] Open
Abstract
CT-P13 is an infliximab biosimilar approved for indications including ankylosing spondylitis (AS); the approved maintenance regimen is 5 mg/kg infused every 6–8 weeks. In clinical practice, modifications to infliximab dose and/or infusion interval can be beneficial to the patient. For CT-P13, real-world data on dose and/or interval adjustment are lacking. This analysis investigated the impact of such treatment pattern changes on effectiveness and drug survival up to five years for adult (≥18 years old) patients with AS in the Korean, real-world, retrospective rheumatoid arthritis and ankylosing spondylitis (RAAS) study. Overall, 337 patients with AS were identified: 219 who initiated infliximab treatment with CT-P13 (‘naïve’) and 118 who switched from reference infliximab to CT-P13 (‘switched’). Overall, 18/235 (7.7%), 110/224 (49.1%), and 101/186 (54.3%) evaluable patients had dose, infusion interval, or combined treatment pattern changes, respectively. More naïve (61.0%) versus switched (42.6%) patients had treatment pattern changes. Overall, Bath Ankylosing Spondylitis Disease Activity Index scores decreased from baseline to week 54, then remained stable; improvements were greater for patients with than without treatment pattern changes. Drug survival did not differ significantly between patients with or without treatment pattern changes. Findings suggest that adjusting dose and/or infusion interval can improve clinical outcomes for CT-P13-treated patients with AS.

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).

Post-marketing analysis for biosimilar CT-P13 in inflammatory bowel disease compared with external data of originator infliximab in Japan. J Gastroenterol Hepatol 2021; 36:2091-2100. [PMID: 33450057 PMCID: PMC8451807 DOI: 10.1111/jgh.15399] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 12/27/2020] [Accepted: 01/01/2021] [Indexed: 12/11/2022]
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 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
INTRODUCTION The use of biological agents in patients with rheumatic diseases has achieved the therapeutic target, i.e., remission or low disease activity. The share of biological agents has been growing with the approval of biosimilars, which have been recognized for their equivalent efficacy, safety, pharmacokinetics, and immunogenicity to the original as well as their reduced economic burden. AREA COVERED Biosimilars are being examined for their bioequivalence to reference products in randomized-controlled trials; however, the use of biosimilars in actual clinical practice is complicated owing to issues with switching and comorbidities. Therefore, this review describes real-world data in the rapidly evolving field of biosimilars in the treatment of rheumatoid arthritis and spondyloarthropathy, including ankylosing spondylitis and psoriatic arthritis. EXPERT OPINION According to published data, the use of biosimilars for inflammatory arthritis led to no significant inferiority in treatment outcomes and resulted in considerable cost savings in the real-world. Currently, beyond the use of biosimilars, issues with the interchangeability of biosimilars, including immunogenicity, should be addressed. Strategies to overcome these concerns will improve treatment efficacy and safety in patients with inflammatory arthritis.
