AI Article Synopsis
- Biologics, including biosimilars like SB5, are complex products that require strict manufacturing controls to ensure their quality and safety, as their quality attributes can significantly affect clinical outcomes.
- This study evaluates 93 batches of SB5, a biosimilar of Humira, produced between 2013 and 2022, to confirm the consistency of its quality profile.
- The findings demonstrate that SB5's purity, charge variants, and functional activities have remained stable over time, meeting regulatory standards despite variations in the manufacturing process.
Article Abstract
Background: Biologics, regardless of whether they are biosimilars or reference products, are inherently variable due to their size, complexity, and the manufacturing process involved to produce them. Since a drift or evolution of quality attributes of a biologic may impact its clinical safety or efficacy, it is critical for the manufacturer to carefully control the manufacturing process and monitor the quality attributes of a biologic.
Objective: The aim of this study was to demonstrate that the quality profile of the SB5 drug product has been consistent over its production history from 2013 to 2022. SB5 is a biosimilar referencing adalimumab (Humira, trademark of AbbVie Biotechnology Ltd) and SB5 has been approved by 14 regulatory authorities including the European Commission in August 2017 (brand name Imraldi™) and the US Food and Drug Administration in July 2019 (brand name Hadlima™).
Methods: A total of 93 SB5 drug product batches manufactured between 2013 and 2022 were analyzed for a series of release parameters to evaluate the consistency in their critical quality attributes including purity, charge variants, and functional activities (TNF-α binding activity and TNF-α neutralizing potency).
Results: The purity, charge variants, and functional activities of all batches were consistent over time and within the stringent acceptance criteria defined by regulatory agencies to ensure the safety and efficacy of SB5.
Conclusion: The data presented in this study provide evidence that the quality of SB5 has remained consistent and tightly controlled even through process changes such as manufacturing site transfers and change in formulation.

Symbiotic anti-oxidant, anti-glycation, and anti-inflammatory qualities of a combination of thiamine and niacin protected type-2 diabetic male rats against both macro and micro-vascular complications.
Iran J Basic Med Sci

Faculty of Medical Sciences, Ardabil, Iran.
Objectives: Increased nuclear factor (NF-kβ) and carbonyl stress due to decreased glyoxalase-1 activity (Glo-I) contribute significantly to insulin resistance and vascular complications. Therefore, we aimed to study the impact of the combination of thiamine and niacin on hepatic NF-kβ signaling, metabolic profile, and Glo-I activity in male rats with type-2 diabetes (T2DM).
Materials And Methods: Forty male rats were divided equally into five groups: control, diabetic, diabetic treated with thiamine (180 mg/l in drinking water), niacin (180 mg/l), and a combination of both.

Introduction: The Quality by Design (QbD) approach for developing cell therapy products using mesenchymal stromal/stem cells (MSCs) is a promising method for designing manufacturing processes to improve the quality of MSC products. It is crucial to ensure the reproducibility and robustness of the test system for evaluating critical quality attributes (CQAs) in the QbD approach for manufacturing of pharmaceutical products. In this study, we explored the key factors involved in establishing a robust evaluation system for the immunosuppressive effect of MSCs, which can be an example of a CQA in developing and manufacturing therapeutic MSCs for treating graft-versus-host disease, , and we have identified method attributes to increase the robustness of a simple assay to assess the immunosuppressive effects of MSCs.

Background: With an aging global population, establishing integrated systems for long-term care is challenging in several countries. Adequate and quality service for older adults in nursing homes can improve their quality of life. The career self-reliance of nurses working in nursing homes may affect the quality of life of older adults; this suggests a need for educational support for career self-reliance behavior.

Post-harvest losses and rapid fruit ripening at room temperature are major challenges in preserving fruit quality. This study aimed to reduce such losses by applying a red carotenoid pigment, bacterioruberin extracted from an sp. The carotenoid was characterized as bacterioruberin and its derivative tetra anhydrous bacterioruberin (λmax 490 nm), and an / value of 675 and 742 (M+ 1H).

Background: The outcomes of simple trapeziectomy (T) versus trapeziectomy with ligament reconstruction and tendon interposition (LRTI) for trapeziometacarpal (TMC) osteoarthritis have been compared in several systematic reviews (SRs) with conflicting results across the various outcomes studied. Despite a lack of conclusions regarding the superiority of one treatment versus the other, LRTI remains the most popular surgical option. This raises the questions of whether published SRs are of high methodological quality, and whether discordant conclusions can be attributed to differences in methodologic quality.
