The PDXs had Bcl-2 and Myc rearrangements...the PDX tumor was resistant to the BTK inhibitor ibrutinib and moderately responsive to the proteasome inhibitor carfilzomib....In contrast, inhibition of the OXPHOS pathway with IACS-010759 significantly inhibited 96% tumor growth (IACS-010759 vs control, p < 0.00001) and prolonged mouse survival by approximately 25 days compared with the vehicle control and the other drugs (IACS-010759 vs control, ABT-199, or ibrutinib, p < 0.0001).
