The first link might answer some of the questions that were asked a day or so about Dr. Schilsky's trial. I think it's clear that those who participated believe the drug warranted further study, even if GSK didn't without a modification to the partnership.
I'm still of the belief that the modification they wanted included C242-DM4 and in the end they weren't willing to pay what IMGN wanted for access to it. This is of course JMHO.
