As your cell therapy products (e.g., CAR-T, TCR-T, CAR-NK) progress into clinical stages, higher demands are placed on process stability, product consistency, and production scale. By optimizing process parameters and strengthening quality systems, we ensure the provision of high-quality, reproducible cell products for pivotal clinical studies (Phase II/III). We effectively manage the complexity of personalized medicines and meet the stringent consistency requirements of multi-center clinical trials.
