BCL2 inhibitor venetoclax was added to enhance the effectiveness of ibrutinib and AZD 1208...CD79B-mutant Val cells and PIM1-mutant OCI-Ly8 cells were more sensitive to Ibrutinib (10 μM)- and AZD 1208 (40 μM)-induced apoptosis (p < 0.01)...Venetoclax (0.1 μM) showed the most synergistic effect on Ibrutinib (10 μM)- and AZD 1208 (40 μM)-induced apoptosis (p < 0.01).
