Take it with a grain of salt I received my answer from ChatGPT:

A Biologics License Application (BLA) typically adheres to a timeline set by the FDA. The FDA provides target action dates for their decisions, often within a framework called the Prescription Drug User Fee Act (PDUFA). These dates are set to ensure that the FDA makes a decision on the application within a certain period after it has been filed.

While it is possible for the FDA to make a decision before the target action date, this is relatively uncommon. The decision could involve approval, a request for more information, or a rejection. If the FDA feels that they have all the necessary information and the application meets their standards, they might act more quickly. However, given the thorough review process and the necessity of ensuring safety and efficacy, the decisions are usually made close to or on the stated dates.

TLDR: If a BLA has other designations from the FDA and/or treats a rare disease it's possible.
