You probably noticed in my post that I cited an intent to complete the 2b/3 OLE as a factor affecting timing.
However, Anavex has less than 50 employees, and only a subset of those will be tasked with completing regulatory AD submissions in Europe and the United States. There won't be very many key figures on that team, the people who can truly professionalize the product at the highest level.
While there will be overlaps in AD submissions, there will also be differences. There will be ongoing conversations with each group of regulators; there will be deadlines for each. Aside from the obvious potential for timing conflicts, there is a significant cost to transferring attention between equally critical projects. I expect management to minimize these concerns by working out separate pre submission timelines. That means not trying to do more at one time than can be well handled.
Larger companies do not have to make these tradeoffs, but this small pre revenue biotech must. Please don't be shocked.
