Overview - What ISO 20404:2023 covers
ISO 20404:2023, "Biotechnology - Bioprocessing - General requirements for the design of packaging to contain cells for therapeutic use," provides high-level requirements and design considerations for packaging that directly contains cells used as medicinal products. The standard applies to packaging for final products as well as starting and intermediate materials, covering primary and secondary packaging design, trial manufacturing, testing and quality management. It does not apply to processing receptacles used in manufacturing (e.g., culture flasks/bags), shipping containers used solely for transport, or services that use packages (e.g., third‑party storage).
Key technical topics and requirements
ISO 20404 emphasizes practical design and risk considerations for packaging used with cell therapies and related bioprocessing products:
- Configuration and content - packaging for suspensions, tissues and other cell configurations, and their accompanying media or additives.
- Enclosing and containment processes - design for the enclosing step and transition through storage, handling and clinical use.
- Disturbance and contamination control - assessment of risks from storage/transport disturbances and potential contamination.
- Leakage and integrity - requirements to minimize leak risk and to consider consequences if leakage occurs.
- Cell–packaging interactions - compatibility between packaging materials and cells, media, cryoprotectants and drugs.
- Usability in clinical settings - ergonomic and operational considerations for clinical facilities and administration routes (infusion, surgery, etc.).
- Environmental impact - life‑cycle and environmental considerations for packaging materials and design.
- Design elements - guidance on shape, layers, ports and material selection for primary and secondary packaging.
- Quality management and implementation - trial manufacture, testing, supplier–user communication and documented quality processes.
- Test methods - examples of methods related to disturbance, leakage and interaction testing (informative guidance).
Practical applications and who uses this standard
ISO 20404 is intended for both packaging suppliers and packaging users in the cell therapy value chain:
- Packaging manufacturers designing primary/secondary packages for cell therapy products.
- Biopharmaceutical developers and manufacturers of cells for therapeutic use (autologous, allogeneic, tissue‑engineered products).
- Clinical product development teams specifying packaging requirements for storage, handling and administration.
- Quality, regulatory and procurement specialists assessing supplier capabilities and design controls.
Use cases include designing leak‑resistant primary containers for cell suspensions, specifying material compatibility for cryopreservation solutions, and establishing supplier–user communication and verification protocols.
Related standards
ISO 20404 references and complements other standards and terminology (e.g., ISO 21973, ISO 11683, ISO 20391‑2) and should be used alongside applicable regional and regulatory requirements for medicinal products and medical devices.
