I didn’t know those details senti, but TFF can certainly be used for DCVax-L. Whether they actually validated the system back then, or Advent is doing it now, shouldn’t really matter in the big picture, but if it was previously validated, then obviously that would be one less task for Advent now. I simply assumed that TFF will be used because I think that Linda Powers wants to control the manufacturing process using NW Bio’s patented systems, as much as possible.
