The cure rate for hepatitis C was very low before Gilead Sciences, Inc. invented Harvoni.
I believe that Anavex 2-73 will become part of the next standard of care for Alzheimer's disease and that Anavex 2-71 could be a cure or at least a prevention for Alzheimer's disease and various other diseases and conditions such as Parkinkson's, Rett's syndrome, Huntington's disease, ALS, epilepsy, etc., etc., etc.
Good luck and GOD bless,
