OK so my reference on timeline of Ph 2 was wrong, but I disagree that they, at least initially, will be doing "shots in the dark" regarding 2-73. That's not how science works, not in academia and especially not in pharma. They must have some data that suggests or reason to believe that 2-73 may have an effect on differentiation of OPCs, otherwise they wouldn't be doing the experiment. They may do further exploratory studies to test other avenues with 2-73, but that by no way means they are "shooting in the dark."
