Yes these are excellent illustrations. However they do illustrate that Bavi is dependent on chemo or radiation. (Bavi is ineffective as a mono-therapy.) The present movement in research is to move beyond the nonselective radiation and chemo agents. It is not at all obvious to me that Bavi will play well with PD-1 or other downstream immuno-stimulative agents. I do hope the current pre-clinical work pans out but success is not assured no matter how hopeful SK was yesterday. I await the results with crossed fingers. And then of course we need confirmation in the clinic.
