regulatory endpoint
A study outcome measure that has been accepted by regulatory agencies for drug approval decisions.
Full Definition
A regulatory endpoint is a clinical outcome measure that regulatory authorities such as the FDA or EMA have determined to be clinically meaningful and appropriate for supporting drug approval decisions in a specific indication. These endpoints must demonstrate clinical benefit that is relevant to how patients feel, function, or survive. In psychiatric research, regulatory endpoints often include established rating scales like MADRS for depression or PANSS for schizophrenia, but they must be supported by evidence of clinical meaningfulness. Regulatory agencies provide guidance on acceptable endpoints for different psychiatric conditions, and sponsors must justify their endpoint selection in discussions with regulators. The choice of regulatory endpoint significantly impacts study design, sample size, and the likelihood of successful drug approval.
Usage
Usage note: Emphasize the regulatory acceptance aspect. Distinguish from endpoints that are merely primary or clinically relevant.
