Regulatory Compliance and Gap Analysis - Overview

Regulatory compliance and gap analysis of the supporting documents/data are critical for registering medicinal products. Though most Health Authorities (HAs) accept applications/dossiers in the CTD format, the content to be provided in the CTD section may vary. Thus, a thorough Regulatory gap analysis/technical assessment of the documents/data enables manufacturers to identify and mitigate the gaps before the submission. It avoids submission rejections and minimizes any major/critical queries to hasten the approvals.

Gap analysis of the legacy dossiers against the current practices followed for the medicinal product’s manufacture ensures Regulatory compliance. The identified gaps can be mitigated by the submission of probable supplements/variations to avoid non-compliance. Freyr, as a proven service provider with experienced Regulatory Affairs CMC resources, provides Regulatory gap analysis support.

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.

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!
