The application that has been submitted is for Advent to manufacture commercial products. It says nothing about DCVax-L.
In the same PR, they say no submission of a BLA/MAA for DCVax-L has been made. They have provided no guidance on the issue, not even saying they plan to submit it.
The bolded portion was to imply that with the manufacturing certification, they will be able to manufacture DCVax/cell therapies but only if those have received regulatory approval.
Basically it's saying that manufacturing will be ready to roll as soon as an approval is granted.
