RE:RE:RE:BTD and pre-BTD overview I'm not sure what you mean be screwup. The BTD process always has had a pre-BTD check in. It is on the FDA website as an opportunity to review the details and clarify if ready for BTD. It is a good thing as the person doing the pre-BTD look over knows more about what would be accepted or not accepted and can tell you what to do to optimize success of application.
