I'm not sure about that but i am unclear about the extra 10 patients they need. I remember that they stated they would have them before the end of the year. The 4-6 weeks timeline for PE and the end of the year for extra 10 patients seem to be relatively close together. I am mostly unsure if they plan to release the PE for the 40 patients and then the extra 10 or just release the full 50 patient PE. Either way, they can't miss on these milestones or decide to hold data that is past due.
