I think the estimated expenses for an AD P3 (>800 subjects) and a Rett P3 are quite conservative. My estimate would be $150 M minimum for the trials alone. The number of objects may need to be higher (the P2/3 of 500 subject did not reach statistical significance for approval). The way Missling runs the company, I put the chances of approval for 273 within 6 years for anything at zero. As for 3-71, see you in a decade if Anavex still exists.
Doc, I apologize for citing the logic of your post so that the class clown commented to you. Can't imagine it is anything other than water off a duck's back.
