Engineering T cells in vivo to express a synthetic cytokine receptor enables preferential expansion and enrichment of anti-CD22 CAR T cells.

Preclinical studies are described demonstrating that UB-VV400 generates anti-CD22 CAR T cells that kill CD22-expressing B cells and tumor cells in vitro and in vivo, and that engagement of RACR results in the selective expansion and enrichment of CAR T cells in vivo leading to complete tumor clearance and B cell deplet...
