I've been to FDA meetings.. research the process... it's all online on the FDA website, call them, ask.. they filed a pre-IND (Investigational New Drug Application). Process will be the same or longer for a biologic... claims and safety are #1 priority and issue with FDA.
Yes, there are laws that say they must respond to you in a certain amount of time, but all they need to do is say we will respond to your request within x # of days, but first submit this, submit that, etc... FDA is backlogged
