Delays in starting the TOX have no bearing on the length of time required for its completion once it has started.
TOX will start soon, and once begun, will take a few months to complete, and a few more months to write up and submit. I'll take BK's estimates that he's provided more than once today.
Constantly rehashing the delays we've all experienced getting to this point won't be the least bit relevant once the TOX studies have begun.
