Psoriasis is a chronic, inflammatory, lifelong disease with a high prevalence (afflicting approximately 1-5% of the population worldwide) and is associated with significant morbidity. The introduction of biologic therapies has improved the management of this disease. Multiple biologic medicines that block cytokine signaling, including tumor necrosis factor (TNF) antagonists (adalimumab, etanercept, and infliximab) and inhibitors of interleukin (IL)-17 (brodalumab, ixekizumab, and secukinumab), IL-23 (guselkumab), or IL-12/23 (ustekinumab), are approved for the treatment of psoriasis...

This policy research aims to map patient access barriers to biologic treatments, to explore how increased uptake of biosimilars may lower these hurdles and to identify factors limiting the increased utilisation of biosimilars. A policy survey was developed to review these questions in 10 Central and Eastern European (CEE) and Commonwealth of Independent States (CIS) countries. Two experts (one public and one private sector representative) from each country completed the survey. Questions were related to patient access, purchasing, clinical practice, and real-world data collection on both original biologics and biosimilars...

OBJECTIVE: Currently, a biosimilar of Remicade is available (CT-P13). Switching patients from Remicade to a biosimilar is still under debate, especially for patients with inflammatory bowel disease (IBD). In a retrospective study, we investigated the feasibility and safety of switching patients with IBD from Remicade to a biosimilar infliximab. PATIENTS AND METHODS: At two large general hospitals in The Netherlands, adult patients with a diagnosis of Crohn's disease or ulcerative colitis being treated with Remicade were asked to switch to the biosimilar infliximab (CT-P13)...

Biosimilar insulins have expanded treatment options for diabetes. We compared clinical efficacy and safety between biosimilar and originator insulins by meta-analysis. Random effects meta-analysis was performed on randomized controlled trials comparing biosimilar and originator insulins in adults with diabetes from electronic databases up to December 2017. Ten trials (4,935 patients) were assessed (2 each for LY2963016, MK-1293, Mylan's insulin glargine, and SAR342434, and 1 each for FFP-112 and Basalog). Meta-analysis revealed no differences between long-acting biosimilar and originator insulins for reduction of hemoglobin A1c at 24 weeks (0...

For the approval of biosimilars, it is, in most cases, necessary to conduct large Phase III clinical trials in patients to convince the regulatory authorities that the product is comparable in terms of efficacy and safety to the originator product. As the originator product has already been studied in several trials beforehand, it seems natural to include this historical information into the showing of equivalent efficacy. Since all studies for the regulatory approval of biosimilars are confirmatory studies, it is required that the statistical approach has reasonable frequentist properties, most importantly, that the Type I error rate is controlled-at least in all scenarios that are realistic in practice...

In 2013, the European Medicines Agency (EMA) approved the biosimilar infliximab (CT-P13) for the full range of indications of the originator product, based on data from two trials conducted in rheumatoid arthritis and ankylosing spondylitis. The same year, our Society published a position statement that was later reviewed.

Trastuzumab improves survival outcomes for patients with HER2-positive (HER2+ ) breast cancer, yet not all such women receive this important therapy. Trastuzumab was approved by the US Food and Drug Administration in 1998 and the European Medicines Agency in 2000 as treatment for HER2+ metastatic breast cancer (MBC). Observational studies between 2000 and 2015 in patients with HER2+ MBC suggest that nearly 12% in the United States, 27% to 54% in Europe, and 27.1% to 49.2% in China did not receive trastuzumab or any other HER2-targeted agent as first- and/or later-line for treatment of metastatic disease...

The absence of a surface-lining mucus layer is a major pitfall for the Caco-2 epithelial model. However, this can be alleviated by applying biosimilar mucus (BM) to the apical surface of the cell monolayer, thereby constructing a mucosa mimicking in vivo conditions. This study aims to elucidate the influence of BM as a barrier towards exogenic compounds such as permeation enhancers, and components of fed state simulated intestinal fluid (FeSSIF). Caco-2 cell monolayers surface-lined with BM were exposed to several compounds with distinct physicochemical properties, and the cell viability and permeability of the cell monolayer was compared to that of cell monolayers without BM and well-established mucus-secreting epithelial models (HT29 monolayers and HT29/Caco-2 co-culture monolayers)...

Human serum albumin one of the most demanded proteins possess an array of clinical and biotechnological applications. Currently, the prime source for HSA production is the human blood which possesses the risk of pathogen contamination and is limited. Thus, there exists an indispensable need to promote non-animal derived HSA production. In the present work, we have exploited the opportunity and promoted the preparation of pathogen-free rHSA from the E. coli host which is blessed with numerous advantages like scalability, cost-effectiveness etc...

Protein A-based affinity chromatography is a highly-efficient separation method to capture, purify and isolate biosimilar monoclonal antibodies (mAb) - an important medical product of biopharmaceutical industrial manufacturing. It is considered the most expensive step in purification downstream operations; therefore, its performance optimization offers a great cost saving in the overall production expenditure. The biochemical mixture-separating specific interaction experiments with Chinese hamster ovary (CHO) cell culture harvest, containing glycosylated extracellular immunoglobulins (Ig), were made using five different state-of-the-art commercial resins...

This article provides an overview of four case studies to demonstrate the utility of pharmacometric analysis in biosimilar development to help design sensitive clinical pharmacology studies for the demonstration of biosimilarity. The two major factors that determine the sensitivity of a clinical pharmacokinetic/pharmacodynamic (PK/PD) study to demonstrate biosimilarity are the size of the potential difference to be detected (signal) and the inter-subject variability (noise), both of which can be characterized and predicted using pharmacometric approaches...

Three biosimilar filgrastim products are currently available in Japan. Among these, the safety and efficacy of two imported drugs for autologous peripheral blood stem cell harvest (autoPBSCH) and autologous peripheral blood stem cell transplantation (autoPBSCT) have been studied widely; however, evidence of the safety and efficacy of domestically manufactured filgrastim is limited. Therefore, we compared the efficacy and safety of domestic biosimilar filgrastim (BF1, n=23) with those of originator filgrastim (OF, n=21) for autoPBSCH and autoPBSCT...

For approval of biosimilar products, the U.S. Food and Drug Administration (FDA) recommends a stepwise approach for obtaining the totality-of-the-evidence for assessing biosimilarirty between a proposed biosimilar product and its corresponding innovative (reference) biologic product. The stepwise approach starts with the assessment of analytical similarity of critical quality attributes (CQAs) for structural/physicochemical and functional properties in the manufacturing process of biosimilar products. For Tier 1 CQAs which are most relevant to clinical outcomes, the FDA recommends an equivalence test be performed for similarity assessment based on an equivalence acceptance criterion (EAC)...
