For the ORR to be released at ASCO it would of had to been unblinded before the abstract deadline of 2/1/2012 because the trial isn't eligible as a late breaker. That could of happened as the increase in trading volume seems to coincide with that timing but on the other hand SK indicated that he was still waiting on the data as of 2/14/2012.
IMO, it's looking like it could be unblinded any time between now and the end of next month.
