Nice preclinical work similar to what the other sigma 1 failures had. I've given links several times to both pre clincal and the failed P2 studies. M1 study abandoned for cognition failure already as well. Pridopidine study. Sounds good pre clinic. https://www.ncbi.nlm.nih.gov/pubmed/30756361
M1 AD trial last year. Abandoned. https://www.sciencedirect.com/science/article/pii/S235287371830012X Plenty of things work well in preclinical studies and plenty of drugs claim autophagy or degrees of homeostasis. Even things other than drugs claim to promote autophagy including fasting.
What I haven't heard is a reason that restoring normal endogenous brain enzyme levels, therefore regrowing the synpatic network would NOT result in successful AD trials. This is no longer preclinical in nature or a hypothesis paper. Its in human trials.
