What are you talking about? First look-in has not yet occurred.
And no, they have not been withholding negative or positive look-in information. It's impossible to hide this information in the real world we live in.
Why do you think first look-in already occurred? 1) if enrollment was slow to ramp up the first 3-6 months and the ecog 0 patients are living 10- 15 months+ vs Ecog 1 living 7- 12 months, then first look-in may not have occurred or may have occurred only very recently depending on the 3-6 month early enrollment window. 2) Joe Shan stated that first look-in would be announced as soon as possible at the last CC .
I do remember reading other board posts that blood work and other tests were being done throughout the trial, so perhaps this is giving some guidance to the collaborations/ partnerships?
