Could be that it takes much more time, still. I don't think it will - and no, "heroic" Rett results are not needed, just a repeat of the 32 patient adult trial in the 90+ patients juvenile trial. IMO, no big deal. As the picture gets clearer and clearer - the quality of the AD data and path to approval, the quality of the Rett data, etc. - if the stock price remains low then just keep accumulating.
