Talon, I agree in theory...
I just think that the FDA would be more likely to give the RMAT designation to drugs that are further along in the clinical development than 273 is at the moment.
Is 273 a candidate down the line? I absolutely think so, but for now, we have to temper our expectations with regards to buyout offers, FDA labels, etc because all things considered, 273 is still in its infancy in the drug development timeline.
A proper P3 trial will probably take at least a year, maybe longer. And we still have some time for the extended P2A; I suspect that Anavex isn't going to want to push forward with a new trial until it's extracted as much data as possible from the current one so as to maximize odds of success when the trial is blinded and controlled.
