Gator, the trial was a P2a that began in early 2015 and while there was NO placebo, there still was a comparison between those taking DPZ and 2-73 (combo therapy) and those only taking 2-73 (Mono).
Those early results showed how the mono-users (7 @ start) performed much better than the combo-users (25 @ start). This showed the power of 2-73 to help the body to stop Alzheimer's when not polluted with DPZ.
That potential still exists today as Anavex works towards trials that will solidify its efficacy in not only one, but, at a minimum, 3 CNS diseases.
ANAVEX NOW ... MONO-STYLE ... RWEm for Life ... and for ALL AGES!!!
