Biologics have revolutionized medical care, yet uniform access to these effective medicines remains difficult due to the increasing costs of healthcare. As patent exclusivity on the early biologics wanes, regulatory and legal systems are adapting to bring competition to the field in the form of biosimilars. Biosimilars are biologics that offer the same clinical benefit in one or more of the same indications as the reference biologic drug and bring competition to the biologics space. Legislation creating a pathway resulting in the first US approvals of biosimilars has been in place since 2010, but the regulatory methodology and science of evaluating the sameness of two biologics has been in use for decades...

PURPOSE OF REVIEW: This review provides an update on the evolution of, manufacturing of, and regulations for biosimilars in Asian countries. RECENT FINDINGS: The use of biologics revolutionized the treatment of various diseases. However, the high cost of biologics remained unaffordable for most Asian patients and increases the financial burden of Asian governments. The development of biosimilars provides the best solution for this predicament. A great boom of biosimilars is developing in Asia...

Nanomedicines in the class of nonbiological complex drugs (NBCDs) are becoming increasingly available. Up to 23 nanomedicines have been approved, and approximately 50 are in clinical development. Meanwhile, the first nanosimilars have entered the market through the generic approval pathway, but clinical differences have been observed. Many healthcare professionals may be unaware of this issue and must be informed of these clinically relevant variances. This article provides a tool for rational decision making for the inclusion of nanomedicines into the hospital formulary, including defined criteria for evaluation of substitutability or interchangeability...

BACKGROUND: GP2013 is a rituximab biosimilar developed to stringent development guidelines, including non-clinical and preclinical investigations and clinical trials in rheumatoid arthritis and follicular lymphoma. We aimed to compare the efficacy, safety, tolerability, pharmacokinetics, and pharmacodynamics of GP2013 plus cyclophosphamide, vincristine, and prednisone (GP2013-CVP) with rituximab-CVP (R-CVP) in patients with follicular lymphoma. METHODS: In this phase 3, multinational, double-blind, randomised, controlled trial, adults (aged 18 years or older) with previously untreated, advanced stage (Ann Arbor stage III or IV) follicular lymphoma of WHO histological grades 1, 2, or 3a were randomly assigned (1:1) using interactive response technology to eight cycles of GP2013-CVP or R-CVP (combination phase), followed by monotherapy maintenance in responders for a 2-year period...

BACKGROUND: Studies in patients with rheumatoid arthritis have shown that the rituximab biosimilar CT-P10 (Celltrion, Incheon, South Korea) has equivalent efficacy and pharmacokinetics to rituximab. In this phase 3 study, we aimed to assess the non-inferior efficacy and pharmacokinetic equivalence of CT-P10 compared with rituximab, when used in combination with cyclophosphamide, vincristine, and prednisone (CVP) in patients with newly diagnosed advanced-stage follicular lymphoma. METHODS: In this ongoing, randomised, double-blind, parallel-group, active-controlled study, patients aged 18 years or older with Ann Arbor stage III-IV follicular lymphoma were assigned 1:1 to CVP plus intravenous infusions of 375 mg/m(2) CT-P10 or rituximab on day 1 of eight 21-day cycles...

Currently, detailed structural characterization of low-molecular-weight heparin (LMWH) products is an analytical subject of great interest. In this work, we carried out a comprehensive structural analysis of LMWHs and applied a modified pharmacopeial method, as well as methods developed by other researchers, to the analysis of novel biosimilar LMWH products; and, for the first time, compared the qualitative and quantitative composition of commercially available drugs (enoxaparin, nadroparin, and dalteparin)...

Hydrogen Deuterium Exchange (HDX) Mass Spectrometry (MS) is a sensitive analytical technique that provides information on protein conformation and dynamics in solution. It is commonly used in the study of protein-ligand and protein-protein interactions and more recently in the pharmaceutical industry for epitope mapping, screening drug candidates and in the comparison of biopharmaceuticals to biosimilars. HDX-MS monitors the exchange of protein backbone hydrogen atoms with deuterium in solution. Recent advancements in HDX automation and data analysis, have taken the emphasis off developing a fundamental understanding of HDX, which is still lacking...

PURPOSE OF REVIEW: After expiry of the patent of originator anti-tumor necrosis factor drug infliximab (Remicade), CT-P13 was in 2013 the first infliximab biosimilar to be approved by the European Medicine Agency (EMA) for the same indications as the reference drug, including paediatric inflammatory bowel disease (IBD). The approval was based on extrapolation, after extensive in-vitro studies and clinical experience in patients with ankylosing spondylitis and rheumatoid arthritis. The extrapolation of CT-P13 to IBD and to paediatric patients raised concerns among paediatric IBD specialists...

Recent developments in medical biotechnology have facilitated to enhance the production of monoclonal antibodies (mAbs) and recombinant proteins in mammalian cells. Human mAbs for clinical applications have focused on three areas, particularly cancer, immunological disorders, and infectious diseases. Tumor necrosis factor alpha (TNF-α), which has both proinflammatory and immunoregulatory functions, is an important target in biopharmaceutical industry. In this study, a humanized anti-TNF-α mAb producing stable CHO cell line which produces a biosimilar of Humira (adalimumab) was used...

A number of low molecular weight heparin (LMWH) products are available for clinical use and although all share a similar mechanism of action, they are classified as distinct drugs because of the different depolymerisation processes of the native heparin resulting in substantial pharmacokinetic and pharmacodynamics differences. While enoxaparin has been extensively investigated, little information is available regarding the LMWH dalteparin. The present study is focused on the detailed structural characterization of Fragmin(®) by LC-MS and NMR applied both to the whole drug and to its enzymatic products...

In recent years, two-dimensional liquid chromatography (2D-LC) has seen an enormous evolution and one of the fields where it is being widely adopted is in the analysis of therapeutic monoclonal antibodies (mAbs). We here further add to the many flavours of this powerful technology. Workflows based on heart-cutting (LC-LC) and comprehensive (LC×LC) 2D-LC are described that allow to guide the clone selection process in mAb and biosimilar development. Combining Protein A affinity chromatography in the first dimension with size exclusion (SEC), cation exchange (CEX) or reversed-phase liquid chromatography-mass spectrometry (RPLC-MS) in the second dimension simultaneously allows to assess mAb titer and critical structural aspects such as aggregation, fragmentation, charge heterogeneity, molecular weight (MW), amino acid sequence and glycosylation...
