Anavex doesn't have to reveal interim data to the TGA, they have it as a function of their EHR records.
They are working with AI in their EHR records. They will know, and I don't think it will take 24 weeks of data because the changes were noticeable at 5 weeks in the P2a. I also don't think it will take 450 people... 50, 100, I don't know but I think the Aussies had a number in mind when the trial started.
