If as I suspect, keytruda increases the potency of DCVax's combo treatment, NWBO and Merck will be forced into a symbiotic relationship and due to NWBO's struggle to survive, we will have to overlook any transgressions that Merck may have committed.
Merck also has no choice whereas NWBO could probably with time conduct trials with other CIs that may or my not be more efficacious than Keytruda but right now I believe that path is still very academic.
