Given the unmet need for anything to treat dementia, anything that really has a positive effect is basically like printing money.

Given the unmet need for anything to treat dementia, anything that really has a positive effect is basically like printing money. It would not be hidden, it would be out there until the patents ran out. And the amyloid situation is a word of warning to anybody thinking they could really speed up drug discovery. The researchers had a model. They created various compounds that were effective vs this model. These compounds were active in vivo vs the model target and safe to deliver. Problem was, they didn’t actually do anything vs dementia. The human body isn’t really well understood. There are unknown mechanisms and interactions that appear at unexpected often undesirable times. There’s things that only show up in human testing, after models and animal testing shows no problems. And as in this case, the disease reveals it’s not really understood. Companies have burned through billions chasing this as the upside is damn well infinite.
