Agree w/your points and would also add that Dr.M. (IMO) is going for the Verification & Validation of the AVXL MOA claims. Restoration and Regeneration evidence is/will be WW breakthrough stuff. RSD, PDD and AD trials are the method of proof (CNS COMPILED evidence from 3 trials). Proof by suitable WW review considering this level all positive will open the WW eyes on CNS the disease spectrum and the AVXL CNS cellular Homeostasis claims are proven. IMO, he is doing multiple trials for this reason. IMO, WS does not see what is REALLY going on w/AVXLyet.
I admit it is unclear right now what can be done to make such a claim credibly (short of actually performing-completing the trials as planned). At some point the combined AVXL trial plans will be linked, Stand by.
It's all about validating the MOA, one CNS indication trial at a time, then a flashover happens.
