CAR-T cell therapy represents a breakthrough in cancer treatment, yet its implementation in developing countries remains challenging due to technical and infrastructural barriers. This study aimed to establish clinical-scale CAR-T production in Kazakhstan, a country with no prior experience in advanced cell and gene therapies. We implemented a complete CAR-T manufacturing pipeline, including in-house lentiviral vector (LV) production and automated CAR-T cell processing using the CliniMACS Prodigy system. Two anti-CD19 CAR LVs were used, one modeled after FDA-approved Kymriah (4-1BB costimulation) and another replicating Yescarta (CD28 costimulation). The vector produced locally achieved functional titers of 1.5 × 1010 TU/mL after concentration. Twelve clinical-scale CAR-T products were manufactured, exhibiting a memory-skewed T-cell phenotype. Functional assessments revealed that CD28-based CAR-T cells produced significantly higher Th1 cytokines (IFN-γ, TNF-α, IL-2; p < 0.05) than 4-1BB-based cells, though both demonstrated comparable cytotoxicity against CD19+ targets. These findings demonstrate the feasibility of establishing CAR-T production in resource-limited settings using a decentralized manufacturing framework. This work provides a scalable model of CAR-T therapy production in developing regions, suitable for clinical implementation using the hospital exemption framework. Critical gaps in access to advanced immunotherapies, including CAR-T, in the Central Eurasia region are addressed.
