Triple Space-Time Yield in Discontinuous Antibody Biomanufacturing by Combination of Synergetic Process Intensification Strategies.

Monoclonal antibodies are the workhorse of the pharmaceutical industry due to their potential to treat a variety of different diseases while providing high specificity and efficiency. As a consequence, a variety of production processes have been established within the biomanufacturing industry. However, the rapidly increasing demand for therapeutic molecules amid the recent COVID-19 pandemic demonstrated that there still is a clear need to establish novel, highly productive, and flexible production processes.

A novel hybrid bioprocess strategy addressing key challenges of advanced biomanufacturing.

Monoclonal antibodies (mAb) are commonly manufactured by either discontinuous operations like fed-batch (FB) or continuous processes such as steady-state perfusion. Both process types comprise opposing advantages and disadvantages in areas such as plant utilization, feasible cell densities, media consumption and process monitoring effort. In this study, we show feasibility of a promising novel hybrid process strategy that combines beneficial attributes of both process formats.

Boosting Productivity for Advanced Biomanufacturing by Re-Using Viable Cells.

Monoclonal antibodies (mAb) have gained enormous therapeutic application during the last decade as highly efficient and flexible tools for the treatment of various diseases. Despite this success, there remain opportunities to drive down the manufacturing costs of antibody-based therapies through cost efficiency measures. To reduce production costs, novel process intensification methods based on state-of-the-art fed-batch and perfusion have been implemented during the last few years.

A novel approach for enumeration of extracellular vesicles from crude and purified cell culture samples.

The interest in extracellular vesicles (EVs) has been increased in recent years due to their potential application in diagnosis and therapy of severe diseases. The versatile fields of application due to the numerous possible cargos and the targeted delivery system make them a promising biopharmaceutical product. However, their broad size range as well as varied surface protein content result in challenges for the purification, characterization, and quantification.
