Same-day CAR-T production is established and refined through the comparison of novel vector and gene-editing strategies with classical methods. Both processes are then standardized to ensure consistent, clinical-scale use. It develops cutting-edge analytical assays - leveraging CRISPR off-target profiling, 3D ex vivo efficacy screens, and cytokine-release monitoring - to qualify edited cells for safety and potency. Finally, it conducts paired comparisons of the new rapid workflow versus traditional ex vivo culture to demonstrate equivalence or superiority in product quality.
