What is it? Why is it important?

Study Set-Up requirements include:


Registering the study in an official website guarantees ongoing research transparency. This is important in order to allow other researchers and the public to gain knowledge and updates regarding current medical research.

Study registration is only possible after EC approval but must be done before study start. Exceptions are Phase I studies, that have the option to be registered for up to one year after study completion.

What do I need to do?

As a SP-INV, check that the study is ready to recruit participants, such as:

  • The study is registered
  • A risk-based QMS is implemented
  • Site staff is properly trained
  • Documentation is up to date (e.g. study initiationTMF/ISF)
  • Site contracts are signed (e.g. responsibilities are defined)
  • eCRF is ready for data entry
  • Processes are in place for the handling of BM
  • IMP/IMD is ready for use
  • Initiation visit is completed


As a Site-INV, ensure:

  • The site is properly initiated by the SP-INV (e.g. IMP use, study staff is trained on study tasks regarding responsibilities, internal study processes, patient inclusion criteria and visit schedule)
  • Protocol instructions on how to conduct the study are clear (e.g. intervention, safety reporting, communication)
  • Document filing is up to date (e.g. ISF)


In Switzerland, a researcher can take on the dual role of being both the SP-INV of the study and the Site-INV. In that case, both responsibilities apply. In order to avoid any conflict of interests, certain services should be hired through external service providers (e.g. study monitoring and auditing)

The SP-INV can delegate selected tasks to a CRO or CTU. However, the main responsibility remains with the SP-INV.

The Site-INV can delegate selected tasks to study staff. However, the main responsibility remains with the Site-INV.
