Post-approval changes can arise throughout the lifecycle of a drug product and must be addressed appropriately. After the product approval and during the commercialization of drug products, manufacturers may propose certain changes to a product and/or active substance for many reasons such as optimising operational costs, increasing productivity, administrative reasons, etc.
Evaluation of such changes must determine whether a submission to the relevant health authorities is necessary, and if it is, a variation package must be prepared. The submission required might be a Type IA, IA, IB or Type II variation package, depending on the categorization of change in accordance with the relevant variation guidelines.
Changes requiring prior to health authority approval must only be implemented after this has been granted, and in many cases, the implementation may be required within a defined period following the approval. Robust post-approval submission strategies and accurate change categorization are critical to minimize health authority questions and to avoid rejections.
In order to maintain compliance, timely submission of changes is essential during the lifecycle of drug products.
