Excellent post. Like you said our drug and the way it interacts with the sigma 1 receptor may show improvements in people in varied ways.
So we are using the CDR as our primary endpoint and the actigraph along with other tools to measure 2-73s effectiveness.
It’s hard to believe but I guess theoretically a person can fail at these endpoints but feel improvements in a whole host of other areas since the receptor is prevalent throughout our bodies. So, I don’t sleep any better and my cognitive deficiencies are still there and possibly decking but my blood pressure is better, my eyesight has improved, etc.
Like others have stated before, it’s hard to see these improvements without the improvement of sleep in conjunction.
