A Multidimensional Analytical Comparison of Remicade and the Biosimilar Remsima.

ABSTRACT: In April 2016, the Food and Drug Administration approved the first biosimilar monoclonal antibody (mAb), Inflectra/Remsima (Celltrion), based off the original product Remicade (infliximab, Janssen). Biosimilars promise significant cost savings for patients, but the unavoidable differences between innovator and copycat biologics raise questions regarding product interchangeability. In this study, Remicade and Remsima were examined by native mass spectrometry, ion mobility, and quantitative peptide mapping. The levels of oxidation, deamidation, and mutation of individual amino acids were remarkably similar. We found different levels of C-terminal truncation, soluble protein aggregates, and glycation that all likely have a limited clinical impact. Importantly, we identified more than 25 glycoforms for each product and observed glycoform population differences, with afucosylated glycans accounting for 19.7% of Remicade and 13.2% of Remsima glycoforms, which translated into a 2-fold reduction in the level of Fc?IIIa receptor binding for Remsima. While this difference was acknowledged in Remsima regulatory filings, our glycoform analysis and receptor binding results appear to be somewhat different from the published values, likely because of methodological differences between laboratories and improved glycoform identification by our laboratory using a peptide map-based method. Our mass spectrometry-based analysis provides rapid and robust analytical information vital for biosimilar development. We have demonstrated the utility of our multiple-attribute monitoring workflow using the model mAbs Remicade and Remsima and have provided a template for analysis of future mAb biosimilars.

Project description:Background: Since the late '90s, infliximab (Remicade®) is being used successfully to treat patients with several non-infectious immune mediated inflammatory diseases (IMIDs). In recent years, infliximab biosimilars, including Remsima® were introduced in clinical practice. Aim: To investigate the interchangeability of Remicade® (originator infliximab) and its biosimilar Remsima® in patients with rare immune-mediated inflammatory diseases (IMIDs). Methods: This two-phased prospective open label observational study was designed to monitor the transition from Remicade® to Remsima® in patients with rare IMIDs. All included patients were followed during the first 2 years. The primary endpoint was the demonstration of non-difference in quality of life and therapeutic efficacy, as measured by parameters including a safety monitoring program, physicians perception of disease activity (PPDA) and patient self-reported outcomes (PSROs). Secondary outcomes included routine blood analysis, pre-infusion serum drug concentration values and anti-drug antibody formation. Results: Forty eight patients treated with Remicade® were switched to Remsima® in June-July 2016 and subsequently monitored during the first 2 years. The group consisted of patients with sarcoidosis (n = 17), Behçet's disease (n = 12), non-infectious uveitis (n = 11), and other diagnoses (n = 8). There were no significant differences in PPDA, PSROs, clinical and laboratory assessments and pre-infusion serum drug concentrations between the groups. De novo anti-drug antibodies were observed in two patients. Seven patients with sarcoidosis and five with another diagnosis developed a significant disease relapse (n = 7) or adverse events (n = 5) within 2 years; 10 of these patients discontinued Remsima® treatment, one withdrew from the study and one received additional corticosteroid therapy. Conclusions: We observed no significant differences in PSROs, PPDA and laboratory parameters after treatment was switched from Remicade® to Remsima®. However, disease relapse or serious events were observed in 12 out of 48 patients when treatment was switched from Remicade® to Remsima®. The choice to switch anti-TNF alpha biologics in patients with rare IMIDs, particularly in sarcoidosis, requires well-considered decision-making and accurate monitoring due to a possibly higher incidence of disease worsening.

Project description:INTRODUCTION:Inflammatory autoimmune diseases (rheumatoid arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, psoriasis, and psoriatic arthritis) have a considerable impact on patients' quality of life and healthcare budgets. Biosimilar infliximab (Remsima(®)) has been authorized by the European Medicines Agency for the management of inflammatory autoimmune diseases based on a data package demonstrating efficacy, safety, and quality comparable to the reference infliximab product (Remicade(®)). This analysis aims to estimate the 1-year budget impact of the introduction of Remsima in five European countries. METHODS:A budget impact model for the introduction of Remsima in Germany, the UK, Italy, the Netherlands, and Belgium was developed over a 1-year time horizon. Infliximab-naïve and switch patient groups were considered. Only direct drug costs were included. The model used the drug-acquisition cost of Remicade. The list price of Remsima was not known at the time of the analysis, and was assumed to be 10-30% less than that of Remicade. Key variables were tested in the sensitivity analysis. RESULTS:The annual cost savings resulting from the introduction of Remsima were projected to range from €2.89 million (Belgium, 10% discount) to €33.80 million (Germany, 30% discount). If any such savings made were used to treat additional patients with Remsima, 250 (Belgium, 10% discount) to 2602 (Germany, 30% discount) additional patients could be treated. The cumulative cost savings across the five included countries and the six licensed disease areas were projected to range from €25.79 million (10% discount) to €77.37 million (30% discount). Sensitivity analyses showed the number of patients treated with infliximab to be directly correlated with projected cost savings, with disease prevalence and patient weight having a smaller impact, and incidence the least impact. CONCLUSION:The introduction of Remsima could lead to considerable drug cost-related savings across the six licensed disease areas in the five European countries.

Project description:Development of bio-therapeutics has exhibited exponential growth in China over the past decade. However, no biosimilar drug has been approved in China (CN) due to the lack of a national biosimilar regulatory guidance. HLX01, a rituximab biosimilar developed in China under European Medicines Agency biosimilar guidelines and requirements, was the first such drug submitted for regulatory review in China, and it is expected to receive approval there as a biosimilar product. To demonstrate the analytical similarities of HLX01, CN-rituximab (sourced in China but manufactured in Europe) and EU-rituximab (sourced and manufactured in Europe), an extensive 3-way physicochemical and functional similarity assessment using a series of orthogonal and state-of-the-art techniques was conducted, following the similarity requirement guidelines recently published by China's Center for Drug Evaluation. The results of the similarity study showed an identical protein amino acid sequence and highly similar primary structures between HLX01 and the reference product (RP) MabThera®, along with high similarities in higher order structures, potency, integrity, purity and impurity profiles, biological and immunological binding functions, as well as degradation behaviors under stress conditions. In addition, HLX01 presented slightly lower aggregates and better photostability compared with the RP. Despite slight changes in relative abundance of glycan moieties and heavy chain C-terminal lysine modification, no differences in biological activities and immunological properties were observed between the RP and HLX01. In conclusion, HLX01 is highly similar to CN- and EU-sourced RP in terms of physicochemical properties and biological activities, suggesting similar product quality, efﬁcacy, and safety. The regulatory requirements interpreted and applied towards the HLX01 marketing application sets a precedent for analytical similarity assessment of biosimilar products in China.
