Can you share any more information about the medical device that showed efficacy against Alzheimers in the 200-patient trial?
There was also benefit across most measures, but just not of statistical significance.
The trial had some major problems with appropriate controls, and is widely cited as a poster child for why the FDA should not require a control group to undergo invasive brain-surgery, and how this can taint the results.
It also showed a 89% reduction in amyloid Beta, the same proxy measure Biogen's aducanumab was recently approved based on.
There are a lot of treatments that's worth dumping several million dollars in even if they are low probability of having durable effects.
I obviously have biases and an axe to grind, but these are my opinions.
