The company has disclosed that intention. Rett is an orphan rare disease, so it is a prime candidate for BTD's. It's disappointing we haven't applied or been granted it (by this time it would have been, it's a relatively simple application, not part of a full clinical report), so the FDA is likely wanting Excellence results; the adult trials showed potential signal, but no apparent dose effect in Avatar. So let's see what Excellence shows. I'll be surprised if TLR comes in by end of H2 2022. It's looking like it's going to be another target date pushback, maybe to Q1 2023.
