Sorry about my spelling errors today but I am posting from my phone and I broke the screen a couple days ago and can't always see when my fingers fumble.
I am sure they would love to see efficacy in the phase 1 but I don't thinl everyone realizes it doeasnt matter. They get the MTD and all these other trials start in combination with other therapies. The best part of that is they are with Pfizer drugs and if just one of them shows early signs of efficacy shareholders are golden and we improve lives of cancer patients.
