BACKGROUND: CT-P10 is the first biosimilar of the anti-CD20 monoclonal antibody, rituximab. CT-P10 is currently available in over 51 countries worldwide, where it is approved in the same indications as its reference product rituximab. In-use stability studies are conducted for biologics to determine how conditions (e.g., temperature, light, humidity, length of time stored) affect drug quality following dilution and storage in infusion bags. OBJECTIVE: We evaluated the in-use stability of CT-P10 for intravenous infusion stored diluted in infusion bags over longer periods than currently recommended by manufacturer guidelines...

Detailed analysis of biopharmaceuticals is crucial for safety, efficacy and stability. Aptamers, which are folded, single-stranded oligonucleotides, can be used as surrogate antibodies to detect subtle conformational changes. We aimed to generate and assess DNA aptamers against the therapeutic anti-CD20 antibody rituximab. Six rituximab-specific aptamers with Kd  = 354-887 nM were obtained using the magnetic bead-based systematic evolution of ligands by exponential enrichment (SELEX) technology. Aptamer folds were analysed by online prediction tools and circular dichroism spectroscopy suggesting quadruplex structures for two aptamers while others present B-DNA helices...

Biologic therapies are an important option in the treatment of patients with rheumatic disease. As the development of potential biosimilars increases, many countries are following the guidelines developed by the WHO, European Medicines Agency, or US Food and Drug Administration to create country-specific regulations for the review and approval of these products. Iraq does not yet have such regulations, and this presents a potential safety concern for patients. The analytical, nonclinical, and clinical data requirements for approval of a potential biosimilar are specific and scientifically rigorous...

The concept of biosimilar was established in the early 2000s in EU. Currently, the regulatory framework for biosimilar has also been established in the US, Japan, and other countries. As of 2018, biosimilars for infliximab, adalimumab, rituximab, trastuzumab, and bevacizumab have been approved. During the development of a biosimilar, product quality should be evaluated and compared with those of the reference product extensively. Among the quality attributes of therapeutic antibodies, FcRn binding and related structures are well known to affect the pharmacokinetic profile of the product...

Doctors are convinced that Truxima, the first rituximab biosimilar approved by the FDA, is as effective as rituximab; European experience with the biosimilar over the last 2 years has also revealed no problems with unexpected side effects. However, cost will be a factor in determining whether doctors in the United States prescribe Truxima instead of rituximab.

PURPOSE OF REVIEW: Since its initial approval in 1997, rituximab has revolutionized the treatment of CD20-positive lymphoproliferative disorders. Now, over two decades later, second-generation molecules are emerging that may have key biological advantages compared to rituximab, as well as biosimilars that may be more cost-effective. Clinicians, health policy makers, and payers will now need to critically appraise the available evidence for these competitors and decide which anti-CD20 to use...

BACKGROUND: Studies in patients with rheumatoid arthritis and advanced follicular lymphoma have shown that CT-P10, a rituximab biosimilar, has equivalent or non-inferior efficacy and pharmacokinetics to rituximab. We aimed to assess the therapeutic equivalence of single-agent CT-P10 and rituximab in patients with newly diagnosed low-tumour burden follicular lymphoma. METHODS: In this ongoing, randomised, double-blind, parallel-group, active-controlled, phase 3 trial, adult patients (≥18 years) with stage II-IV low-tumour-burden follicular lymphoma were randomly assigned (1:1) using an interactive web or voice response system stratified by region, stage, and age to CT-P10 or US-sourced rituximab...

The advent of monoclonal antibody biosimilar products has stimulated the development of analytical methods that can better characterize an important quality attribute, namely the higher order structure (HOS). Here, we propose a simple approach based on heteronuclear 2D NMR techniques at natural abundance for generating spectral fingerprints of the HOS at high resolution. We show that the proposed method can assess the HOS of six therapeutic products, adalimumab (Humira®), bevacizumab (Avastin®), infliximab (Remicade®), rituximab (Rituxan®), trastuzumab (Herceptin®), and Etanercept (Enbrel®)...

Biological products for treatment of rheumatoid arthritis usually are cost effective for healthcare systems in Europe, but they are huge financial burden due to the high number of patients and the significant budget impact. The expected saving from introduction on the market of biosimilars are significant and are linked to better access and affordability. The aim of this study was to conduct comparative price analysis of biological products for rheumatoid arthritis therapy among seventeen EU countries. The point of view is that of the Bulgarian pricing and reimbursement system and the chosen countries are those from external reference basket for prices comparison at manufacturing level...

Rituximab is a chimeric mouse/human monoclonal antibody (mAb) therapy with binding specificity to CD20. It was the first therapeutic antibody approved for oncology patients and was the top-selling oncology drug for nearly a decade with sales reaching $8.58 billion in 2016. Since its initial approval in 1997, it has improved outcomes in all B-cell malignancies, including diffuse large B-cell lymphoma, follicular lymphoma, and chronic lymphocytic leukemia. Despite widespread use, most mechanistic data have been gathered from in vitro studies while the roles of the various response mechanisms in humans are still largely undetermined...
