Regulatory Classification of Non-Interventional Studies: When Do They Require Approval? Understanding When Non-Interventional Phase 4 Studies Require Regulatory Approval Introduction Not all clinical research conducted post-approval is interventional. In Phase 4 clinical trials, many studies fall under the category of non-interventional studies (NIS), where the treatment is prescribed as per routine clinical practice. However, there’s…
