Cost Analysis of Cell Therapy Manufacture: Autologous Cell Therapies, Part 2

by , and

In part 2, we continue to analyze manufacturing costs of an autologous cell therapy. A typical process involves the expansion and activation of cells derived from a single patient, which is currently very labor-intensive. To date, there is little published information on overall production costs (1). In part 1, we used a software modeling platform to identify opportunities for potential cost savings. We developed a baseline model of a cell therapy manufacturing process using the production of autologous dendritic cells…

Cost Analysis of Cell Therapy Manufacture: Autologous Cell Therapies, Part 1

by , and

Cell therapies are a growing area of interest for the treatment of a number of indications such as neurological, cardiovascular, and ophthalmological maladies that are refractory to other more conventional drug therapies. A number of cell-based therapy products currently are undergoing clinical trials. The most common target is oncology, which represents 46% of all cell-based therapies through the use of traditional blood-cell and immune-cell–based therapies. For treatment of various cancers, immune cells, lymphocytes (natural killer cells, T cells, and B…

Standardized Economic Cost Modeling for Next-Generation MAb Production

by , , , and

Historically, in generating material for clinical testing during antibody process development, emphasis was placed on efficacy, product quality, regulatory compliance, and speed. As the biopharmaceutical industry has matured (and with increasing competition), emphasis has shifted toward cost optimization and manufacturability. Reducing the costs of medicines for patients and payers (thereby broadening access to drugs) is now a key driver during development of new therapies as well as modernizing processes for existing molecules. Cost reduction includes providing robust manufacturing processes that…

Cost-Effective Process Development for Plasmid DNA Manufacture: Evaluation of Single-Use Technologies to Support Escherichia coli Culture

by , , and

DNA-based gene therapy products have been in clinical development since the 1990s. But over the past 24 months, the overall demand and therapeutic applications for plasmid DNA (pDNA) have rapidly grown and expanded. Currently, pDNA can be used directly as a therapeutic agent (e.g., in gene therapy or generation of vaccine antigens) and indirectly for a range of applications. Those include its use as a critical starting material for transient transfection to produce both viral-vector constructs (e.g., lentivirus or adenoassociated…
