What is it? Why is it important?

The ability to conduct a study is largely based on the ability to comply with requirements defined by the Ethics Committee (EC), the law (e.g. Swiss law), including relevant standard (e.g. ISO) and guidelines (e.g. ICH GCP, Declarations of Helsinki and Taipei).


Both EC and if applicable Swissmedic will initially evaluate the study and decide whether the study can be approved for implementation.


The overall aim is to ensure that:

  • The safety, rights and confidentiality of study participants are protected
  • The quality and integrity of study data is guaranteed
  • The documentation of the investigational product (IMP/IMD) is available and fulfils quality obligations


In order to ensure that studies are conducted in accordance with given laws, regulations, directives and guidelines, requires that:

What do I need to do?

Aspects to consider are:

  • Scientific validity: the degree to which the study question accurately reflects and assesses the concept a researcher is trying to measure
  • Recruitment: a fair selection of study participants, inclusion of consenting participants, special handling of vulnerable participants
  • Resources: trained and educated study staff, required infrastructure and equipment, sufficient time available to implement the study
  • Risk-benefit ratio: participant safety takes precedence over scientific interest
  • Data handling: Protection and confidentiality of study data, including traceability and protection against damage and loss
  • Handling of biological material: Correct handling, protection against damage and loss, confidentiality of genetic data, infrastructure for long term storage
  • Budget: guarantee financial coverage until study completion, including archiving and possible storage of biological material
