They really can't jump the timeline past the consideration they already received (Fast Track, Orphan Drug Designation and Priority Review), and the hearsay you quoted is incorrect. Brainstorm's estimate is for topline (preliminary) data availability in mid 2020, not treatment availability. Not too long ago, they were planning top line data a year earlier. Things slip.
Then they will need final data before they can finish filing for registration, which the Fast Track allows them to do in installments. Next, there is an expedited review process that can still take up to 6 months, instead of the usual 10. Of course, if the trial is positive, the FDA will try to act as quickly as possible.
I have attached one of their recent decks.
Again, we don't know the results of the trial as yet. This dosing regimen is new, in an effort to improve the results. That means there could be more side effects.
Also remember they are requiring "rapid progressors" for this trial, based on the Phase II results, and no one >60.
So only time will tell for whom it works and how well, even if approved. It could all be wonderful, but we have no way to know as yet.
Because a lot can get garbled, we don't usually host secondhand reports of threads elsewhere. Let's leave it to our readers, Jaclyn, to check out the threads they're interested in.
