A Change of Ownership Application (COA) is the regulatory process by which an MA can be transferred from one marketing authorisation holder (MAH) to another. Most commonly this occurs when a company acquires an MA or is merged with or acquired by another company.
The process by which an MAH may transfer ownership of an MA varies greatly from market to market. In some cases a simple notification by letter is sufficient; in others a new MA must be sought.
Aside from the regulatory tasks, logistically a Change of Ownership needs carefully planning to ensure timely liaison with all necessary functions within the organisation ensuring the smooth transition from one livery to another thus maintaining continuity of supply to the market.
