What is a 505(b)(2) New Drug Application

A 505(b)(2) application differs from a typical new drug application, in that the process to approval could potentially be quicker with less expense.  The 505(b)(2) process takes drugs that have already been approved and makes small modifications to them. Typically a company will perform a phase 1 bridging study to compare the systemic levels of the proposed drug product and the reference product.  A bridging study also allows a company to reference the safety and efficacy information that is known for the original drug.
There are three advantages for a company that pursues a 505(b)(2) application.
1.  It is a relatively lower risk process because the original drug may have already been proven to be safe.
2.  The entire process is lower cost.
3.  The pathway to approval can be quicker because of the fewer studies required.
Companies such as Auspex, and Concert Pharmaceuticals, who attempt to improve the metabolic, safety, or efficacy profile with the use of deuteration, could benefit greatly by following the pathway of a 505(b)(2) submission application to get to market quicker, with less expense.  As those drugs get approved quicker, with less expense, the benefit should fall to the patient in need, and our medical healthcare system that provides insurance coverage.  Thank you for reading.
