Current Industry Best Practice on in-use Stability and Compatibility Studies for Biological Products.

Evaluating the in-use stability of a biological product including its compatibility with administration components allows to define handling instructions and potential hold times that retain product quality during dose preparation and administration. The intended drug product usage may involve the dilution of drug formulation into admixtures for infusion and exposure to new interfaces of administration components like intravenous (iv) bags, syringes, and tubing. In-use studies assess the potential impact on product quality by simulating drug handling throughout the defined in-use period.

Examination of the Protein Drug Supply Chain in a Swedish University Hospital: Focus on Handling Risks and Mitigation Measures.

Protein drugs, such as monoclonal antibodies, have proved successful in treating cancer and immune system diseases. The structural complexity of these molecules requires careful handling to ensure integrity and stability of the drug. In this study, a failure mode and effects analysis was performed based on a Gemba Walk method in a Swedish University Hospital.

Suitability of transiently expressed antibodies for clinical studies: product quality consistency at different production scales.

Transgenic human monoclonal antibodies derived from humanized mice against different epitopes of the Middle East respiratory syndrome coronavirus (MERS-CoV), and chimeric llama-human bispecific heavy chain-only antibodies targeting the Rift Valley fever virus (RVFV), were produced using a CHO-based transient expression system. Two lead candidates were assessed for each model virus before selecting and progressing one lead molecule. MERS-7.

Zoonoses Anticipation and Preparedness Initiative, stakeholders conference, February 4 & 5, 2021.

The Zoonoses Anticipation and Preparedness Initiative (ZAPI) was set up to prepare for future outbreaks and to develop and implement new technologies to accelerate development and manufacturing of vaccines and monoclonal antibodies. To be able to achieve surge capacity, an easy deployment and production at multiple sites is needed. This requires a straightforward manufacturing system with a limited number of steps in upstream and downstream processes, a minimum number of in vitro Quality Control assays, and robust and consistent platforms.

Rapid and accurate in silico solubility screening of a monoclonal antibody library.

Antibodies represent essential tools in research and diagnostics and are rapidly growing in importance as therapeutics. Commonly used methods to obtain novel antibodies typically yield several candidates capable of engaging a given target. The development steps that follow, however, are usually performed with only one or few candidates since they can be resource demanding, thereby increasing the risk of failure of the overall antibody discovery program.
