Here is figure 4 from the AACR poster by Cheng and Thorpe on HCC and Sorafenib. It shows the synergy between 2aG4 (mouse version of bavi) and Sorafenib. Note how 2aG4 alone is no better than the control, but sorafenib induces PS exposure and then the combination of 2aG4 and sorafenib is significantly better than sorafenib alone.
