Efficacy & Safety Assessment

AcceGen offers comprehensive in vivo efficacy assessment services, utilizing xenograft tumor models established on their proprietary C-NKG mouse with depleted T, B, and NK cells. This model is ideal for evaluating the therapeutic activity of drugs, including cell therapy products, as well as for constructing human immune system models. In addition, we possess expertise in constructing syngeneic mouse tumor models and maintain an extensive tumor model database, providing customers with a wide range of options for in vivo efficacy assessment.

Service case

Three days after tumor modeling using Nalm-6 cells, mice were intravenously injected with PBS, T cells (1×107 cells), and CAR-T cells (1×107 cells) for observation and recording. The results demonstrated a significant prolongation of the survival period in mice injected with CAR-T cells, accompanied by a delayed tumor growth.
