Not they are not. They are ATL insider saying LL said this.
We have no info on what she allegedly said before or after that.
As for timeline: - There is a "Pre MAA Submission" timeline to follow. + An MAA submission timeline to follow. (including stop clock)
They submitted their Pip plan in Feb 2022. Which mean they started working on "pre MAA submission package in" ~ Oct 2021. (make sense). Their goal was to submit MAA in Sep2022. So they might announce MAA submission with JA next. (hopefully). Then we know we are ~ 8-12 months away from aproval or refusal. Would be nice to have a look at JA before this time, so we have a better idea about pulling out or keep being invested.
