Smart Modular Package Units for Single-Use Processing: Addressing Cost, Speed, and Flexibility Challenges in Biologics Manufacturing

How to reduce costs, while still increasing speed, and flexibility in biologics manufacturing currently represent major issues for the biopharma industry. In this article, Burkhard Joksch, Product Manager Bioprocess Automation and Stuart Tindal, Product Manager FlexAct® Platform at Sartorius Stedim Biotech GmbH, detail the evolution of automation for single-use technology towards modular packaging units. They also including case studies of how these units can be used in real life cGMP processes, as well as explain the manufacturing and industry benefits…

Monitoring Live Biomass in Disposable Bioreactors

Often simply referred to as capacitance, radio-frequency (RF) impedance has been used for over two decades to measure online biomass. It is generally regarded as the most robust and reliable method to monitor live-cell concentrations in mammalian cell culture (1). Many biopharmaceutical companies have now made the transition from conventional glass or stainless steel multiuse (MU) vessels to single-use (SU) bioreactors. Disposables are rapidly becoming the preferred platform for new processes requiring current good manufacturing practice (CGMP) compliance. At the…

The Potential Application of Real‑Time Release Testing for the Biomanufacture of Autologous Cell‑Based Immunotherapies

Cell-based immunotherapies (iTx) are emerging as a truly transformative therapeutic modality that is both complementary and convergent with existing regenerative medicine approaches, including gene therapy, cell therapy, and tissue engineering (Figure 1). Critically, iTx offer step-change improvements in efficacy compared with current standards of care (1) for a range of clinical indications and unmet therapeutic needs — particularly oncology. The clear efficacy of iTx is in contrast with some previous regenerative medicine approaches, including early mesenchymal stem cell (MSC) therapies…
