Practice-Based Clinical Experience Studies (PESs) are:

• A. Only voluntarily conducted by companies
• B. Never requested by the FDA
• C. Always requested by the FDA
• D. Sometimes requested by the FDA

Answer: (D)

Practice-Based Clinical Experience Studies are real-world investigations conducted in typical clinical settings to gather data on how a product performs outside the controlled environment of trials. The FDA may request or require these studies when there are uncertainties about safety, effectiveness, or how the product is used in everyday practice after it reaches the market. Because the need for real-world data varies by product and what is already known, PESs are not automatic or solely sponsor-initiated; they can be prompted by regulatory questions. So, this statement reflects how such studies fit into post-market data collection: they are sometimes requested by the FDA.
