PhRMA on FDA Negative Controls Workshop
Pharmaceutical Research and Manufacturers of America (PhRMA) says it appreciates FDA efforts to meet its PDUFA 7 commitment to discuss negative control methods in real-world data studies and their potential to enhance and modernize the agency drug safety system. The comments came in response to the FDA 3/8 public workshop on the topic.
PhRMA suggests that FDA share its experience with using negative controls and assessment of their validity, when appropriate and to the extent that they can at future annual Sentinel Initiative public workshops or in other appropriate forums. It also recommends that the agency consider using negative control methods beyond Sentinel safety evaluations to detect potential unmeasured confounding and its impact when designing real-world evidence studies.
The letter includes specific comments.
