A science based approach to qualifying replenishment working cell banks, an industry view

Cell banks represent the fundamental starting substrates for biological drug substance (DS)/drug substance intermediate (DSi) manufacturing. Therefore, the availability of well-characterized cell banks capable of supporting manufacturing processes is imperative to ensure uninterrupted drug product supply to patients and global markets.

To this end, two-tier cell banking systems are developed, consisting of master cell banks (MCBs) and working cell banks (WCBs). Typically, WCBs are derived from the MCB to preserve the long-term integrity of the MCB. Although WCB inventories (e.g. vials, ampoules, bags) are generally developed in plentiful supply, over time it is necessary to replenish WCB inventories to meet product demand.

Recent experience shows that regulatory requirements for introducing replenishment WCBs in many countries are highly variable in terms of requirements for supporting data and reporting categories. This results in inconsistent expectations among different health authorities.

This paper examines the scenarios under which replenishment WCBs are manufactured, including when they are replenished and introduced according to the initially registered process (‘like-for-like’ replenishment). It highlights several changes to cell bank manufacturing and materials that can occur when WCBs are replenished.

Its goal is to ensure a consistent cross-industry expectation for an acceptable replenishment WCB qualification strategy using a risk-based scientific approach, considering the potential impact on cell bank growth, viability performance and product quality.

There are few circumstances where replenishing a WCB is likely to impact the phenotype of the WCB or quality of the DS/DSi. Even when changes are necessary to either the cell banking process, cell bank materials or location of cell bank manufacture, the risk of not meeting criteria for qualification (e.g. KPIs) is low for replenishment WCBs.

This will focus on, filing and review, interactions with Health Authorities, and harmonization. Our mission is not just to discuss, but to deliver applicable outputs and publications that will have an impact – learn more about how you can get involved.

Supply Chain to Patient

The pharmaceutical outbound supply chain was built on a blockbuster model and doesn’t fit the needs of the changing pipeline and new modalities currently being developed. The geopolitical challenges of recent years have shown that the outbound supply chain needs to evolve to become more agile, and resilient, and address a more expectant end-user bying on patient-centricity. Industry collaboration can accelerate improvements and transform performance in a way not possible when working independently. This Phorum is founded on the belief that learning from each other and challenging current thinking to re-imagine the supply chain can reduce costs and increase efficiency.

Supply Partner

BioPhorum SP members want the inbound supply chain for the biomanufacturing industry to be recognized as one of the best-understood and managed global supply chains. They intend to be not only a trusted advisory group but also the engine that drives change for the industry. Working together, we aim to achieve supply chain transformation that provides:

  • an enhanced robustness and resilience
  • accelerated capability and capacity to effect technology adoption
  • reduced cost of quality, and
  • industry-wide alignment on operational implementation

Introducing MediPhorum

The medical technology (MedTech) industry is a critical and complex sector. As highlighted during the Covid-19 pandemic, the MedTech industry provides a wide array of products and technologies that are vital to the safe and effective provision of care to many. Also, as seen over recent years, there is often the requirement for flexibility in supply, rapid development, and the introduction of new products to keep pace with global public health demands.

Advanced Wound Care and Wound Management

Advanced wound care (AWC) is the medical treatment for wounds that have not healed properly using conventional wound care products such as gauze, bandages, plasters, and wadding.

AWC involves treating chronic or complex wounds using products that are not as easily obtained over the counter. AWC can be divided into three main categories: wound healing, infection prevention, and restoration.

Drug Delivery

Drug delivery products are therapeutic and diagnostic products combining drugs, devices, and/or biological products, which enable safer and more efficient treatment due to careful and precise drug targeting, local administration, and tailored treatment.
