A quiet period declaration can’t be used in and of itself to avoid announcing something that has happened already. The point of the quiet period is to avoid premature disclosure of details that might cause issues with a regulator or two or create potential legal liability spawning lawsuits and/or to do both.
The reason people are discussing approval is not because approval is directly connected to release of TLD, by some rule, or hard connection, but because of possible practical reasons that have left that as a fallback to address issues that have yet to be resolved by more appropriate means by a primary regulator. Various circumstances could change that not just including resolution of the regulator’s delayed final announcement. So nothing is directly dependent on anything, but if you have an approval in hand, then other issues that may be a good reason for a journal to delay publication, dissolve. And so do regulatory and legal risks.
As for manufacturing, it is in the guidance and details from the FDA that they need to be able to readily produce DCVax-L to achieve any accelerated status, and they need that to get into special programs like Project Orbis, though the have PIM status in the UK and that covers a lot of ground on that across the board.
I agree that I do not think they necessarily need Flaskworks certified to be approved, just a practical plan that the regulator feels comfortable with, and I agree you definitely do not need manufacturing in place to publish TLD, but if you’re going for approval, any approval to address other practical issues, then yes, it can become a practical reason to have the scaling plan well in place, to get the accelerated approval that basically suggests you’re the new standard of care.
It’s like playing Jenga, lots of pieces, and some have fallen in a way that they have become unexpectedly connected or dependent or interwoven with the overall project, and pulling out one or another can have frustrating consequences, but in the case of this situation, it is not quite the same level of causality, it would be to ensure the proper legal of care to not scramble the effort and undermine it by unnecessary mistakes.
This is all my humble opinion. I have no special information but my due diligence and experience.
