AstraZeneca Comments on FDA QTc Draft Guidance

AstraZeneca has submitted both general and specific comments on an FDA draft guidance on QTc information in human prescription drug and biological product labeling. The company’s general comments were:

  • the guidance does not define what the agency considers to be clinically relevant QTc interval prolongation;
  • additional guidance is needed on study requirements for the “through QT/QTc study” cited in the guidance;
  • guidance on how to update labeling materials when new QTc information becomes available should be considered; and
  • the guidance does not emphasize the role of the integrated nonclinical and clinical risk assessment as presented in the International Council on Harmonization E14 and S7B guidances.
