Refining and validating the consumable cassette and core instrument to meet GMP specifications for on-site CAR-T production is performed in this working package: partners will iterate on the Point-of-Care (PoC) - cell and gene therapy cassette design (affinity capture, washing, concentration) and verify cell-isolation performance (purity, viability, yield) across multiple donor samples. Standardized quality-control cartridges and protocols will be developed to automate cell counts, viability checks, and contamination assays, by stakeholder feedback from WP8. Finally, a Digital Twin will integrate process and quality control data into hospital EHR/LIMS systems, enabling real-time interoperability and streamlined clinical workflows.
