BH3 mimetics targeting BCL-XL have efficacy in solid tumors with RB1 loss and replication stress

Abstract BH3 mimetic drugs that inhibit BCL-2, BCL-XL, or MCL-1 have limited activity in solid tumors. Through assessment of xenograft-derived 3D prostate cancer models and cell lines we find that tumors with RB1 loss are sensitive to BCL-XL inhibition. In parallel, drug screening demonstrates that...
