Don't underestimate LP. That's why I guess she never clears the BMY or MRK CI combo trials yet. Like longfellow told us we may never need them and thus we are toxic free; may be they need us. L said Come with the checkbook before; but after TLD, come with your bank.
Read the paper where LL and team basically prove PDL1 is actually inefficient by itself and also doesnt do anything when used in conjunction with DC. They also prove DC alone is amazing on its own.
