Circumstances dictate top line critical stats should be correct while underlying supporting stats which are shared may be fine tuned, though any stats with serious questions should be withheld and not divulged initially but reserved for confirmation. Startups tend to show their lack of horsepower when they stretch too far and stumble but it does not change the directional facts.
My opinion only but I am not sure AVXL did not have agreement from RA's to conduct this trial and publish its results as a titratable drug assuming safety has been studied at both ends of the range and guidelines for titration have been established prior to the trial. As we all know there are many drugs that are administered to patients in practice on a titratable basis such as cholesterol drugs as one example. There has been much work on adaptable trials to make them more conducive to product development and approval decision making. Maybe this type of patient dosage management is what AVXL sought to establish and had agreement to study it that way given their prior safety and efficacy studies.
I have followed AVXL from a distance for a long time, GLTA!
