What is it? Why is it important?

Study monitoring requirements are:




A study monitor:

  • Is in most cases the main line of communication between SP-INV and study site
  • Is independent of the study site being monitored (e.g. foremost the Site-INV),  including any study activities to be monitored
  • Reports to the SP-INV ongoing study progress, including recorded irregularities at the study site
  • Supports the study site to ensure compliance with the study protocol, GCP, and applicable laws and regulations (e.g. HRA , swissethics guidelines)

What do I need to do?

As a SP-INV define which Swiss law(s) is applicable to your study.

Monitoring activities are:

  • Mandatory for studies conducted under the ClinO and ClinO-MD
  • Possible but not mandatory for studies conducted under the HRO


When deciding to include a monitor in your study:

  • Make sure you employ a qualified monitor
  • Be aware that the monitor should work according to an SOP, that describes monitoring procedures, including respective staff responsibilities (e.g. how to plan, set up, and conduct study monitoring)


The SP-INV can delegate monitoring activities to a contractor/CRO/local CTU, but remains responsible for the quality of any delegated services. As agreed, the SP-INV or the delegated party is responsible to provide applicable monitoring SOPs.

Where can I get help?
