If it is the MRVF, then MRK most likely will partner with $ONCS with substantial upfront monies to fund the trial. MRK can risk failure but $ONCS cannot risk. A failure for MRK is "pocket change". Based on the Investigator trial there could be a 16 to 17% response success for the non-responders which would make it worthwhile for MRK and Keytruda.
