3 Stakeholder Comments on FDA QTc Guidance
Pharmaceutical Research and Manufacturers of America (PhRMA) says it is concerned that an FDA draft guidance on QTc information in drug and biological product labeling does not fully embrace approaches discussed in a related International Council on Harmonization guideline. “We have concerns that the draft guidance effectively discourages the use of an integrated risk assessment as a substitute for a clinical Thorough QT study to demonstrate low risk for clinically relevant QT prolongation,” the PhRMA comment letter says….“Internationally harmonized guidance is particularly important because it helps ensure alignment among ICH member regions, preserves efficiency in pharmaceutical research, development, and manufacturing, and facilitates patient access to medicines more efficiently. We encourage FDA to revise the draft guidance to facilitate an internationally harmonized approach to the adoption of the [ICH guidelines] and application of the integrated risk assessment.”
