George.....excellent DD on the preclinical prowess of AF710B or Anavex 3-71. It is the latest of three scientific studies and published abstracts on A 3-71
1. 2016 - Fisher A, Bezprozvanay, Wu - Isreal
2. 2017 - Hall H, Fisher A, Cuello AC, - McGill University, Canada
3. 2019 - Cuello AC, Hall H - McGill University, Canada
These studies are all highly positive about A 3-71's preclinical effectiveness against AZ and can be found at your link.
And by the way, look at who the last study's researchers were associated with..........
"ACC is the holder of the Charles E. Frosst/Merck endowed Chair in Pharmacology and a member of the Canadian Consortium on Neurodegeneration in Aging. The authors are grateful for the unrestricted support provided by Merck Canada."
