Development processes must be adapted specifically for cell-based drug products. Regulatory T-cell therapy represents a promising new frontier in the immunotherapy of autoimmune disorders, especially for patients who have been refractory to available treatments. Because of intrinsic fragility, cell therapy products can be highly sensitive to variations in manufacturing procedures. Standardization of drug-product cryopreservation and storage…
