Sky has mentioned many times: combination is the king.
To tackle all these tumor-associated immunosuppressive characteristics, combination is the way. IMO, NWBO has achieved the most crucial milestone in treating cancer: triggering massive and sustainable t cell infiltration into tumor sites. The next step is to take care of immunosuppresion of different types. Of course, adding CYT107 to increase t cell counts should be included in the future trials too.
Guess which company has most of the inhibitors can be used in future clinical trials to tackle immunosuppresion.
