Overall, the engineering of a single-vector targeting IL10R CAR, which subsequently secretes CD33-targeted bsAb, addresses the issue of immune escape due to the heterogeneous expression of IL10R and CD33, and represents a promising progress in AML therapy aimed at improving treatment outcomes.
The discovery of the role of galectin-1 in cell surface CAR down-regulation provides important insights for developing strategies to restore anti-tumor functions.
Immune cell therapy has become a cornerstone in cancer therapy. When administered in combination with daratumumab, QN-023a demonstrated superior ADCC compared to unmodified iPSC-derived NK cells against primary AML blasts from patients. Together, we have engineered iPSC-derived QN-023a NK cells as promising clinical drug candidates for treatment of AML.
