What is the chance that this is really kind of BS? Presumably their is no cost to BMY for agreeing to this clause (assuming it is well defined). Yeh, if they want to run trials for cancer then a payment is possible, but perhapse they have 0 intent of ever doing such. Nobody will ever see the fine print.
Maybe a $1B deal just sounds cool. Gets the new management off to a flying start.
P.S., I am very long ZGEN so not bashing here.Just very much a cynic in Bioworld.
