When you know what we did and why we did it, you will understand
At the time of that quote, Missling had no clue how well or not A2-73 would perform clinically.
Just stating 'All end points met' in the P2b/3 trial doesn't tell us anything about how well A2-73 performs in the clinic (that missing n thing associated with the Odds Ratio thresholds). Biogen/Eisai released lecanamab data that met all endpoints by the book, but I think we can all agree that didn't mean amazing clinically meaningful outcomes.
We still need to fully appreciate how well A2-73 actually performed in the clinic. We are again waiting on another peer reviewed paper to more fully understand the P2b/3 results, but with fewer limitations, than we now understand the very small open label P2a results.
