100% of the AL patients joined the extension trial. Conclusion - PBT2 is working.
Funny how no one reads the data. Think about it, if you just completed a trial (IMAGINE) and it did not work for you, would you turn around and sign up for the extension trial and continue therapy? Nope. But what happened, 100% of patients completing IMAGINE, signed up for the extension trial - conclusion? PBT2 is working for those patients.
As far as I read it, 13/17 = 76% joined the extension trial. That is a great number and means that safety and side effects are good. Now how many of these were on PBT2 and how many on placebo. Was the dosing 50-50 ? If so also some of the placebo patients feel better.
