What is it? Why is it important?

The aim of monitoring is to verify or notice particular things.

As in daily medical practice, activities are monitored and inconsistencies are corrected. These processes are especially important when conducting a study.

The purpose of study monitoring is to verify that:

  • Participants’ safety, rights, and well-being are protected
  • The quality and integrity of study data is guaranteed
  • A study is conducted in compliance with the study protocol, GCP, and applicable laws and regulations.

What do I need to do?

As a SP-INV select a study monitor who:

  • Is appropriately trained and has experience in study monitoring
  • Has relevant scientific knowledge
  • Is thoroughly familiar with the study protocol, GCP, study IMP/MD, including applicable laws and regulations


The study SP-INV is responsible to appoint a qualified study monitor. The SP-INV can delegate monitoring tasks to a contractor/CRO/local CTU, but remains responsible for the quality of any delegated services.
