CRS in all pts was manageable and resolved after treatment with Ruxolitinib, SOC and supportive care. Robust CAR-T cell expansion was observed in DL2 at 1.5x10 7 cells/kg in heavily pretreated r/r B-ALL patients, including those previously treated with CD19 or CD19-CD22 CAR-T therapies. The study is ongoing and continues accruing patients.
It demonstrated robust anti-tumor efficacy and promising potentials to suppress HvG. This report presents an example that the dual CAR design of GC502 may serve as a novel “off-the-shelf” CAR-T technology.
