Biogen's AA was 10 months after the NDA was submitted.

Actually, Eisai/Biogen had the Accelerated Approval BLA (biologic equivalent of NDA) accepted for review on July 5, 2022 and was concurrently granted priority review. 6 months later they got accelerated approval (Jan 5,2023) and they received conventional approval July 6, 2023. Breakthrough therapy had previously been granted in 2021 which allowed rolling submission

I think its very noteworthy that not only was the phase 3 initiated before AA in January, the TLD had been released at CTAD end of November AND a peer reviewed NEJM article of the phase 3 was out. Therefore, AA approval was low risk for the FDA. They took only 8 weeks after the end of study to report TLD at CTAD.
