RBN013209 is an orally active, small molecule inhibitor of CD38, exhibiting potent inhibitory activity with an IC₅₀ ranging from 0.01 to 0.1 μM against human CD38. It effectively blocks the enzymatic conversion of extracellular NAD⁺ to ADPR and cADPR in both tumor cells and peripheral blood mononuclear cells (PBMCs), thereby modulating the tumor microenvironment.
Beyond its direct antitumor potential, RBN013209 also enhances the efficacy of immunotherapies. It preserves the naïve and central memory phenotypes of CAR-T cells, while reducing the expression of activation markers and exhaustion-associated inhibitory receptors. These properties position RBN013209 as a promising agent for both tumor research and the development of combination strategies to improve CAR-T cell persistence and function.
