ANDA Post-approval Changes

Unlock the full potential of your approved ANDAs with Freyr's post-approval change management services. From major manufacturing site changes to minor administrative updates, we provide expert guidance to navigate FDA regulations and optimize your generic drug portfolio.

ANDA Post-approval Changes - Overview

ANDA post-approval changes are important throughout the lifecycle of a generic drug product. After the approval of a generic drug application and during the commercialization of the drug product, manufacturers may propose certain changes to an ANDA/DMF to optimize the operational cost, increase productivity, or due to administrative reasons. These post-approval changes are submitted to the US FDA by filing supplements or amendments per Section 506A of the Federal Food, Drug, and Cosmetic Act and § 314.70 (21 CFR 314.70).

Based on the impact and complexity, changes to an approved ANDA have been categorized as major, moderate, and minor, and the types of submissions and the necessity for prior approval from the US FDA before the change implementation are varied.

Timely submission of the respective supplement/amendment/annual report is critical to maintain the lifecycle of the product and be compliant. In case of an inappropriate categorization of the change, preparation of a post-approval submission strategy is crucial to avoid rejections from the US FDA.

Freyr’s Regulatory affairs team has extensive knowledge and experience in handling US FDA post-approval changes to ANDA and DMF, with their submissions aligned to the requirements and guidelines of the US FDA.

I am sure you have heard by now that we have received our first-ever approval from the FDA for our Brands division. This is a major milestone for us as well as for my team here in Reg Ops. I would be remiss if I didn’t point out that we would not have been able to do this without the help of your dedicated team. From the original filing, then the following year of responses, all helped get us to final approval.

Thank you Freyr team for a job well done!

Please relate to the team the excellent job they have done on the IND reactivation. Specifically, the high-quality module 3, written by Freyr. It was very comprehensive, very few revisions were required, and we had no questions from Health Canada or FDA. No CMC questions: that was a first for me. So very responsive to my many requests, which I am sure can be frustrating but always helpful while producing excellent work.

Thank you for always being available and responding quickly and comprehensively to all my requests.

What a great team you have, Freyr.
