What is it? Why is it important?

After a preliminary approval round, Swissmedic might still have some remaining issues that need clarification (e.g. IMP labelling, Swiss Expert Committee for Biosafety). As a consequence, Swissmedic can request a Late Clarification Meeting (LCM). This avoids additional rounds of text reviews and saves time.


For the LCM Swissmedic will:

  • Forward any remaining and open issues to the SP-INV in writing
  • Request that the SP-INV decides on the preferred communication mode (e.g. by teleconference, in writing)


Chronology of a Swissmedic application including the potential for an Early- and Late clarification meeting:

  • The SP-INV submits the study to Swissmedic
  • Swissmedic forwards a list of questions to the SP-INV
  • SP-INV requests an Early Clarification Meeting (ECM)
  • Upon the ECM, Swissmedic reaches a preliminary decision with some remaining questions
  • The SP-INV replies to Swissmedic questions
  • Swissmedic requests a Late Clarification Meeting (LCM)
  • Upon a LCM, Swissmedic reaches a final decision regarding study approval

What do I need to do?

As a SP-INV:

  • Inform Swissmedic of the preferred communication mode within 5 days
  • After Swissmedic agrees on the selected communication mode:
    • Reply in writing to all open issues within 10 days
    • Contact Swissmedic and agree on a meeting within the next 5 to10 days


For the LCM:

  • Swissmedic chairs the meeting
  • Only prepare answers to questions forwarded by Swissmedic
  • Be short and concise
  • Take minutes during the meeting
  • After the meeting, submit minutes to Swissmedic for approval
