Optimizing cell culture media — a critical factor in bioproduction
Growing success in biotherapeutic production
The development of biologics-based therapies is part of the ongoing quest to improve human health. Since their introduction in 1982, biologics have been blazing new trails for the treatment of a broad spectrum of diseases. New therapies driven by technological advances in bioproduction have led to exciting opportunities to improve human health while addressing new patient populations and unmet medical needs.
Biologics are complex, large-molecule therapeutics manufactured in living systems such as microorganisms, insect cells, or animal cells; human cells that have been genetically reprogrammed to attack specific disease targets are also considered biologics. Biologics may include a wide range of products, such as proteins, antibodies, messenger RNA (mRNA), and advanced therapy medicinal products (ATMPs).
Recombinant DNA technology led to the development of recombinant insulin, first produced in 1978 and made commercially available in 1982.1 Recombinant human insulin continues to be a mainstay of treatment for type 1 and advanced type 2 diabetes mellitus.1
The first monoclonal antibody was fully licensed in 1986 for the prevention of kidney transplant rejection.2 Today, monoclonal antibodies are indicated for the treatment of a variety of conditions including cancer and cardiovascular, infectious, and autoimmune/inflammatory diseases.
For decades, scientists pondered the seemingly endless therapeutic potential of mRNA in the field of cancer.3 But the urgency of the coronavirus disease 2019 (COVID-19) pandemic spurred the rapid development and commercialization of the first mRNA vaccines approved by the U.S. Food and Drug Administration (FDA).4 Researchers are now exploring applications of the technology as a tool against emerging coronavirus variants and other infectious diseases, such as human immunodeficiency virus (HIV), Epstein-Barr virus, and cytomegalovirus (CMV).5-9
Scientific research continues to drive therapeutic discovery with ATMPs, a fast-growing field of innovation.10 These groundbreaking products are expected to address challenging therapeutic targets that have evaded conventional therapies, slowing disease progression, and perhaps even offering the promise of a cure for diseases that were once considered incurable. In the United States, these technologies, which include cell and gene therapies such as chimeric antigen receptor (CAR) T-cell therapies, are expected to revolutionize the treatment paradigms for many complex conditions.11
Seven of the top 10 best-selling medicines globally are biologics.12 Of the 209 drugs approved by the FDA from 2000 to 2008, 7.17% were biologics.13 This number has increased exponentially in recent years: 15.56% of the 302 drugs approved by the FDA from 2009–2017 were biologics.13 In 2021 alone, 28% of the 50 drugs approved by the FDA were biologics,14 including an mRNA COVID-19 vaccine and CAR-T therapies.15,16
Cell culture media: the foundation for success
Because biologics are manufactured in living organisms such as animal and microbial cells, as the field of biotherapeutics continues to grow, so will the demand for bioprocessing and related services. Yield and quality of product is heavily dependent on the cell culture process, a crucial component of which is cell culture media optimization. As new large-molecule therapies hit the drug development pipeline, relying on the expertise and capabilities of companies like FUJIFILM Irvine Scientific’s Media Development and Optimization (MDO) program to co-create custom formulations helps address product-specific bioprocessing challenges in real time.17
One of the biggest challenges in the development, manufacture and commercialization of any advanced therapy comes early on, when cell culture media and workflow decisions are made. When first choosing cell culture media, focus is typically placed on its functionality— how it will affect cell expansion and viability, whereas considerations as to its scale-up potential and regulatory compliance might be overlooked.
For instance, media that work at a small scale may rely on complex or undefined components, such as human serum, which can introduce the possibility of manufacturing errors later in the scale-up process. Appropriate packaging must also be considered when scaling-up cell culture, as it requires that media bottles typically used in small-scale studies be replaced by bag or powder formats in automated, large-scale processes. In addition, it’s important to ascertain whether the media is available in all regions where the therapy will be manufactured, and assess the stability of the supply chain for all ingredients in the formulation, particularly for advanced therapies such as CAR T-cell therapy that require a constant supply of media for cell expansion.
Understanding and accounting for regulatory requirements in media formulation and process development is yet another important consideration in the early stages of protocol design and media optimization. Early development is often achieved using commercially-available media with poorly defined or undefined components, while media used in the clinical development and commercial manufacturing stages must meet international regulatory guidelines and local requirements.18 Achieving these considerations early in the development process can ensure high-quality production and save valuable time and money.
FUJIFILM Irvine Scientific's deep expertise in cell biology and cell culture optimization makes them a leading cell culture media supplier. Through the supply of quality media, they help customers navigate the journey from early-stage development to clinical applications and commercial manufacturing.
