Bio-Techne And Carterra Initiate A Clinical Research Collaboration For COVID-19 Variant Analysis

Bio-Techne, a leading supplier of high-quality and innovative tools for life science research, therapeutic manufacturing and clinical diagnostics and Carterra Inc., the world leader in high-throughput antibody screening and characterization, today announced a clinical research collaboration studying COVID-19 variants. New variants, such as Delta, can be more easily transmitted and more likely to evade the immune response of vaccinated or previously infected people. To assess immune responses to new variants and to plan for intervention mechanisms that avoid vaccine escape, scientists and epidemiologists need a fast and effective assay.

The partnership leverages Carterra's flagship analytical platform - the LSA® - to characterize panels of SARS-CoV-2 spike and receptor-binding domain (RBD) variants in an information-rich assay. The SARS-CoV-2 variants were developed by Bio-Techne and used to fast-track the new, scalable assay for measuring the potential risks that new variants may evade the ability of the immune system to block the virus.

Bio-Techne has been leading the way in COVID-19 research reagent and immunoassay development enabling scientists to make discoveries leading to effective diagnoses, therapies and vaccines. The company was first to market with COVID-19 research protein variants and has significant expertise with SARS-CoV-2 antibody quantitation. Bio-Techne and Carterra will focus this collaboration on more than 40 variants, including the Delta variant that is prevalent today, and emerging variants as they are discovered.

The Carterra LSA will be used to generate high-definition insights with over 120 data points from patient serum samples, including a variant profile, ACE-2 blocking potential, and isotyping profiles of immunoglobin response. The LSA's hands-free, high-throughput setup requires only 2 µL of patient serum and provides for the analysis of new and emerging variants in the ever-evolving field of COVID-19 research.

Carterra's LSA instrument is the fastest, most sensitive and flexible biosensor platform on the market. Combining proprietary flow printing microfluidics with High Throughput Surface Plasmon Resonance (HT-SPR) technology, the LSA enables detailed screening and characterization of vast antibody or variant libraries, including full kinetic profiles. With the ability to generate real-time binding data for 384 proteins on one chip and assay up to 1152 patient samples in a single unattended run, the LSA significantly improves efficiency and speed in both drug discovery and clinical research.

Stevanato Group Launches EZ-fill® Kit and Laboratory Fill and Finish Service to Support Small Batch Drug Development and Commercialization

Stevanato Group | January 25, 2024

Stevanato Group S.p.A. a leading global provider of drug containment and delivery solutions to the pharmaceutical, biotechnology, and life sciences industries, unveiled today two new offerings for efficient small batch pharmaceutical manufacturing: the EZ-fill® Kit and the non-GMP laboratory fill and finish service at its Technology Excellence Centers (TEC). In a context where reducing time-to-market is key, Stevanato Group’s new EZ-fill® Kit offers fast access to a customizable and versatile solution to pharma and biotech companies needing to efficiently fill small batches with high-quality injectable formulations during clinical trials or commercial phases. The surge the industry has seen in biopharmaceuticals treating various diseases in several therapeutical areas may signal a significant growth potential for pharmaceutical companies. Injectables, comprising more than 60% of the over 21,000 drugs currently in development, of which 44% are biopharmaceuticals, require high-performance primary packaging and delivery technologies for proper storage and administration. Stevanato Group’s EZ-fill® Kit builds on its existing ready-to-use platform of pre-sterilized containment solutions – vials, cartridges, and syringes – allowing customers to effectively screen different primary packaging in combination with drug products. The kit will be available as a modular box made up of glass ready-to-use drug containers and add-on components on request, shipped by courier. As a result, the platform can bring enhanced levels of quality and safety to patients across the entire drug life cycle and improve the rate at which new drugs enter the market. EZ-fill® Kit will be presented at Pharmapack and is expected to be available commercially beginning in the second quarter of 2024. Additionally, to better support customers, Stevanato Group has introduced a non-GMP laboratory filling and finishing service at its Technology Excellence Centers (TEC) in Boston, USA, and Piombino Dese, Italy. This new service allows customers to assess and identify the possible effects of the fill-and-finish process on their product performance as early as the container selection stage, thus de-risking processes and enhancing development and commercialization strategy. “In the race to bring new advanced biopharmaceutical products to market and to patients, Stevanato Group is tackling the challenge of supporting customers with flexible drug containment and filling solutions in a timely manner," says Fabio Bertacchini, Senior Director EZ-fill® Vials & Cartridges at Stevanato Group.
