2-73 has some promise but our clinical trials have not been definitively successful compared to the pre-clinical support.
Because the entire company (and all the other alzheimers trials of all the other companies), are based on a completely nonsensical unsupportable and primitive theory, which actually is a bit ridiculous. That the brain or central nervous system of a rat or mouse is fundamentally similar to a humans. The theory is dicey on its face. The human brain is not analogous to a limb, the muscle or skeleton tissue of a human. All the other human systems are completely different from the human brain, other than that they are organic (so is a tree or a shrub), other than it is lodged inside a human. The human brain is something we have no idea how it works, nor will we for the next thousand years (probably 10,000 years ). It is engaging in 100,000 mysterious processes per second. The brain has as much similarity to the other human structures as a nuclear submarine has similarities to a large cuban savanna cigar. BTW, who said the "preclinical" (such a big word) trials of anavex with mice have any significance or are themselves statistically significant in the world of rats? It is all a clue and a prayer, let alone thinking that the silly liquid solutions that biotech companies assemble in a lab will in any way materially affect the human brain. Because somebody can rebuild a broken toilet does not mean their "solutions" permit them to build the James Webb Space Telescope. False leap of logic, motivated by money. The assumptions are absurd, so the test results of the FDA will be proven absurd. You can throw 20 buckets of paint up against a ceiling and I guarantee if you do it a million times, against a million ceilings, you will never come up with the Cristine Chapel. Try doing it 50 million or 100 million times, same result, slop on a wall. The alzheimers experimenters are better off thinking they can change the way the brain functions by "bleeding" the people in their arms or legs, the way people believed 500 years ago........
