Decision-Support Tools for Monoclonal Antibody and Cell Therapy Bioprocessing: Current Landscape and Development Opportunities

Industrial-scale manufacturers in a number of fields — from automobiles to biotherapeutics — have long relied on powerful computational and mathematical tools to aid in the scale-up, optimization, quality control, and monitoring of product development (1–5). Typical process pathways are highly multifactorial, with numerous branch points, feedback steps, instrumental attributes, and target parameters. Moreover, margins for error are minimal for most industrial processes, requiring high standards of precision from industrial and operational pathways (6). For those reasons, the complexity of…

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…
