Placement of Integrated Summaries of Safety and Effectiveness (ISS/ISE) in Applications Submitted in the eCTD Format

The CTD summary sections in Module 2 are not the correct location for the integrated summaries of safety and effectiveness (ISS/ISE) required by 21 CFR 314.50 (see ICH M4: The CTD -- Efficacy Q&As.

CTD submissions are being submitted electronically, it is important that the location of ISS/ISE information in an eCTD be consistent:

  • In an eCTD, the ISE and ISS go in Module 5, section 5.3.5.3.
  • If the narrative portions of the ISE and ISS are suitable for use in Module 2, sections 2.7.3 and 2.7.4 of the CTD, the documents are placed once in these sections and referenced in Module 5, section 5.3.5.3 (i.e., provide leaf elements in section 5.3.5.3).

The following table lists the various sections of the CTD that contain summary and integrated discussions of efficacy and safety and the corresponding FDA regulations, where applicable, that inform the content of those sections. Any questions about these matters can be raised with the appropriate reviewing division at FDA.
