Doktor, why are focused on PD-L1's now? If it's an attempt to understand the science, I applaud you. I have minimal knowledge on the science.
But if it's concern over the outcome of the trial, then it's too late. The hay is already in the barn. Even if PD-L1's aren't present in the same quantity for all cancers and all patients, I think it's a given that they are going to be present in a significant number of patients in the trial. If DCVax is duped by the presence of PD-L1s, the vaccine will fail.
I think it's why John's reminder about the early data is important. That data is why I jumped into NWBO as an investment. I don't need to know the science if I know the data. Time will tell if the phase III data is as good.
