Downstream Technology Landscape for Large-Scale Therapeutic Cell Processing
Bioprocess International
The Cell Therapy Industry has an opportunity to
learn from protein processing and
anticipate downstream processing bottlenecks by
proactively developing technologies to
address future scales. Cell Therapy companies
are in a unique position to take their
industry to the next level of scalable
manufacturing by using functionally
closed, single-use technologies that can
process hundreds of liters of cell
suspension in a single batch. Here, we

them to newly developed, scalable
downstream bioprocessing technologies
in terms of efficiency, scalability, degree
of automation, cost, and applicability to
large-scale volume reduction and

Potency assay development for cellular therapy products: an ISCT review of the requirements and experiences in the industry
Cytotherapy
The evaluation of potency plays a key role in defining the quality of cellular therapy products (CTPs). Potency can be defined as a quantitative measure of relevant biologic function based on the attributes that are linked to relevant biologic properties. To achieve an adequate assessment of CTP potency, appropriate in vitro or in vivo laboratory assays and properly controlled clinical data need to be created. The primary objective of a potency assay is to provide a mechanism by which the…
The evaluation of potency plays a key role in defining the quality of cellular therapy products (CTPs). Potency can be defined as a quantitative measure of relevant biologic function based on the attributes that are linked to relevant biologic properties. To achieve an adequate assessment of CTP potency, appropriate in vitro or in vivo laboratory assays and properly controlled clinical data need to be created. The primary objective of a potency assay is to provide a mechanism by which the manufacturing process and the final product for batch release are scrutinized for quality, consistency and stability. A potency assay also provides the basis for comparability assessment after process changes, such as scale-up, site transfer and new starting materials (e.g., a new donor). Potency assays should be in place for early clinical development, and validated assays are required for pivotal clinical trials. Potency is based on the individual characteristics of each individual CTP, and the adequacy of potency assays will be evaluated on a case-by-case basis by regulatory agencies. We provide an overview of the expectations and challenges in development of potency assays specific for CTPs; several real-life experiences from the cellular therapy industry are presented as illustrations. The key observation and message is that aggressive early investment in a solid potency evaluation strategy can greatly enhance eventual CTP deployment because it can mitigate the risk of costly product failure in late-stage development.

Meeting Lot Size Challenges of Manufacturing Adherent Cells for Therpy
Bioprocess International
Here, we examine the three platforms available for producing adherent cells — planar technologies, packed-bed systems, and suspension platforms such as microcarriers and aggregate cultures — for their potential of meeting lot requirements at different scales. As new production methods are introduced, we propose addressing downstream processing bottlenecks before they occur and introduce some large-volume downstream process technologies.

Developing Assays to Address Identity, Potency, Purity, and Safety: Cell Characterization in Cell Therapy Process Development
Regenerative Medicine
A major challenge to commercializing cell-based therapies is developing scalable manufacturing processes while maintaining the critical quality parameters (identity, potency, purity, safety) of the final live cell product. Process development activities such as extended passaging and serum reduction/elimination can facilitate the streamlining of cell manufacturing process as long as the biological functions of the product remain intact. Best practices in process development will be dependent on…
A major challenge to commercializing cell-based therapies is developing scalable manufacturing processes while maintaining the critical quality parameters (identity, potency, purity, safety) of the final live cell product. Process development activities such as extended passaging and serum reduction/elimination can facilitate the streamlining of cell manufacturing process as long as the biological functions of the product remain intact. Best practices in process development will be dependent on cell characterization; a thorough understanding of the cell-based product. Unique biological properties associated with different types of cell-based products are discussed. Cell characterization may be used as a tool for successful process development activities, which can promote a candidate cell therapy product through clinical development and ultimately to a commercialized product.

Peak Serum: Implications of Serum Supply for Cell Therapy Manufacturing
Regenerative Medicine
The cell therapy industry (CTI) is emerging as a distinct and competitive component of global healthcare, creating value for investors and pro- viding life-changing therapies to patients [1,2].

The cell therapy industry (CTI) is emerging as a distinct and competitive component of global healthcare, creating value for investors and pro- viding life-changing therapies to patients [1,2]. Industry growth has necessitated an increased focus on large-scale manufacturing strategies to meet future demands [3,4]. One major chal- lenge is the limited availability of some crucial raw materials used in cell therapy manufactur- ing – including bovine serum. Without a sus- tainable supply or viable alternatives to these components, the commercial-scale production of cell therapies will be impossible, halting the momentum of the industry. We propose that solutions to these challenges are achievable, and can be expedited by industry-wide collaboration.
Bovine serum is currently used in the majority of cell therapy manufacturing processes. Current stocks and production rates of serum suitable for GMP manufacture may only be sufficient to support the production of one blockbuster cell therapy. Limitations in the availability of bovine serum thus act as a major cost driver and sig- nificant barrier to the commercial success of the industry as a whole. Thus, without an increase in serum production, or at least a significant increase in the development and implementation of serum-free production strategies, the growth and sustainability of the CTI will be severely constrained.Other authors -
