Verifying the MoA is no longer anywhere near as important as proving whether in real-life A2-73 provides sufficient clinical benefits shown by clear trial results.
That proof is hopefully closer, but the full data to demonstrate that is missing in action, still...
You are highly respected here by many, including me! So MOA works, but why does it take so very long to present data results when many here feel it's just a few weeks to maybe several months?
This information is absolutely critical to speaking with the FDA let alone get into a "waiting period" of many months to get to talk with them for the eventual ability to apply for an NDA.....which probably takes a very long time......yeah, I guess that explains the ATM.
