This whole thread, including my posts, is becoming (or always was) in IMO completely irrelevant to $AVXL. Mainly because we can't buy shares in United Neuroscience, at least not yet.
Finally, the recent UB-111 P2 trial was in 43 patients with three arms: two treatment arm and a placebo arm. The positive results were not stat sig. In comparison the A2-73 treated 32 patients and was not placebo controlled, but met all endpoints. I would argue that the A2-73 adaptive crossover trial design yielded far more information about A2-73 than a similar size 3 arm placebo controlled design would.
Aside from all that and more importantly, IMO, is that A2-73 addresses an upstream mitochondrial dysfunction that also in turn stops the protein misfolding that leads to plaque and tangles.
