The transition of cell therapies from the research lab to the clinic is not always straightforward. In particular, selecting and qualifying ancillary materials (AMs; also referred to as raw materials) can be challenging and confusing for researchers and cell therapy manufacturers. The absence of definitive regulations for AMs, and for supplier compliance claims, results in regulatory ambiguity for both cell therapy manufacturers and AM suppliers. To determine the best solution and smoothest pathway to the clinic, it is therefore critical for cell therapy manufacturers and AM suppliers to work closely together to understand their respective regulatory and compliance requirements and capabilities.
Find answers to common questions about qualifying AMs for cell therapy manufacturing below, and learn how STEMCELL can partner with you to navigate the process more efficiently.
Ancillary materials (AMs) are components, reagents, and materials used during the manufacture of cell therapy products, but they are not intended to be part of the final product. The term “ancillary material” is not globally recognized by regulators and nomenclature varies by region (e.g. in Europe they are referred to as “raw materials”). AMs may include cell isolation reagents, culture and cryopreservation media, and disposables such as plasticware and bioprocessing bags.
The quality of AMs is widely recognized as having a potential impact on the efficacy, safety, and consistency of a cell therapy. Therefore, AMs must be carefully evaluated for their chemical and biological characteristics as well as their effects on the final cell therapy product. Importantly, establishing the safety and suitability of an AM is critical to gaining approval for cell therapy products.
How are AMs qualified for cell therapy manufacturing?
AM qualification refers to the process of establishing the source, identity, purity, biological safety, and general suitability of a given AM.
Selecting and qualifying necessary AMs for the complex production of cell therapies can be both challenging and confusing for manufacturers. It is impossible to provide a “one-size-fits-all” qualification program for every situation and manufacturers are advised to follow a risk-based approach.1 For example, while a growing number of AMs are produced under Good Manufacturing Practices (GMPs), the specific AM that performs the best for your cell therapy application may not have been manufactured under GMP. The question then, is: “Must it?”
While there are still no specific and definitive regulations for AMs, there are resources and guidelines for developing AM qualification programs, such as from the United States Pharmacopeia (USP); the International Organization for Standardization (ISO); and the European Pharmacopoeia (Ph. Eur.).2-4 For a more detailed overview on qualifying AMs, please refer to the Technical Bulletin: Ancillary Material Qualification.
What are cGMPs?
cGMP stands for current Good Manufacturing Practices. GMP are a series of processes, policies, and controls within a quality management system (QMS) that ensures the resulting manufactured product is safe and efficacious for its intended use. “Current” signifies that although the regulations for GMP were put in place decades ago, compliance to these regulations must include current industry standards, science, and technology. In general, cGMP and GMP may be used interchangeably. The compliance requirements of GMP extend through the product life cycle and include design, manufacture, testing, labeling, and more.
Do all AMs for cell therapy require manufacture under cGMP?
The regulations will vary by region, but the use of AMs manufactured under relevant cGMPs may not be strictly required to produce cell therapies for preclinical and early-phase clinical trials. For more information on the use of AMs in cell therapy manufacturing, please refer to the Technical Bulletin: Ancillary/Raw Material Qualification.
STEMCELL may be able to support the use of our products as AMs even without GMP by following the qualification framework outlined in Chapter <1043> of the United States Pharmacopeia (USP) or Ph. Eur. 5.2.12,2,4 which provide guidance on assessing the safety of ancillary materials. We manufacture AMs under our robust quality management system (QMS), which often demonstrates sufficient control to support preclinical and early-phase clinical trials. Our Services for Cell Therapy team is available to work with you to define your specific quality requirements and design a solution that best fits your needs.
What “grade” of AM does cell therapy manufacturing require?
Contrary to widespread belief, globally there is no particular grade of AM that is required for use in cell therapy manufacturing. Indeed, any claim that a product is of “cell-therapy grade” reflects market-driven nomenclature rather than an accepted regulatory compliance standard. However, AMs manufactured under a robust quality management system (QMS) present a reduced qualification burden for cell therapy manufacturers. For this reason, it can be preferable to source AMs that are manufactured under relevant cGMPs or that are themselves approved, cleared, or licensed therapeutic products or medical devices.
It is important to note that even an approved therapeutic product used as an AM must be validated for applications outside of its intended use. In other words, GMP or other regulatory approvals do not guarantee that a particular AM is the best choice for manufacturing your final cell therapy product.
For more information on the respective accountabilities for AM suppliers and users, see Table 2 in Solomon et al. 2016.1
How can cell therapy manufacturers streamline AM qualification?
Ultimately, the responsibility for AM qualification lies with the cell therapy manufacturer. The process can be made more efficient, however, by partnering closely with the AM supplier, who can make the path to AM qualification easier to navigate.
Suppliers can assist manufacturers by providing quality documentation, allowing facility audits, communicating proactively about AM changes, and providing increased testing or custom formulations. Establishing strong working relationships and clear communication with AM suppliers at an early stage can also enable manufacturers to anticipate and resolve issues or concerns related to the use of an AM.
For a review of case studies of manufacturers and AM suppliers collaboratively resolving quality or regulatory issues, refer to Table 3 in Solomon et al. 2016.1
