Yes.
Regardless of a patient's RSBQ score, they only counted a patient as a responder IF the Physician CGI-I score was 1-3. That is the threshold requirement.

All other RSBQ scores that are positive go into the placebo category!!!

I'm pretty sure that is not the case.

Data is kept within the group that generates it. RSBQ scores that do not rise to the threshold to show improvement are kept within the drug receiving group if that is where the data came from.

What the 39% score in the placebo groups shows is how variable the RSBQ scores can be. Missling said they can vary as much as 300%. What that tells me is that the Rett girls can have good days and bad days. And when there are only a few data points taken the variability can be very high depending on whether the data taking day happens to be a good day or a bad day for the individual patient.

In 2004, I was cured of Plaque Psoriasis that covered 95% of my body. The medication was Enbrel which was first approved in 1999 for arthritis. I found it curious that Missling used this condition as a trial example when explaining the anchored RSBQ. I recall my doctor telling me that patients responding to the medication saw plaque clearance rates of 75%, so clearly Amgen had established an endpoint that was a dramatic outcome for the patient. Though even a 50% clearance would have been clinically meaningful, $35,000 per year in cost would not have been worth the benefit, especially with moderately effective topicals available at a fraction of the cost.

I don’t quite understand the concerns I am reading regarding Trofinetide. We all know it is inferior in effectiveness and has some, well rather uncomfortable side effects for wheel chair bound patients. I wouldn’t be so certain that the fda approves their drug, in light of the fact it has no effect on adult patients, and used for a primary endpoint what we all now realize is an error prone RSBQ score comparison between 2 points in time. Caregiver bias is a given. Even if approved and on the market before Blarcamesine, if you were the caregiver of the patient, would you not switch to the more effective, fewer side effect option; and alternatively if you were a physician recommend your patient switch meds; and if you were an insurance company manager, steer payment to the better indication.

We got this!
