What is it? Why is it important?

The International Council on Harmonisation (ICH) Good Clinical Practice (GCP) E6, defines international ethical and scientific quality standards for designing, conducting, recording, and reporting studies involving human participants.

 

ICH GCP E6 builds on key concepts outlined in ICH E8(R1) “General Considerations for Clinical Trials”. These documents are complementary guidelines that act together to ensure the:

 

ICH GCP E6 guidelines provide standards that:

  • Foster a quality culture in study planning and conduct, while supporting a risk-based approach towards factors critical to study quality
  • Facilitate the mutual acceptance of internationally performed studies (e.g. Switzerland, EU, US, Japan, Australia, Canada, Nordic countries, WHO)
  • Ensure principles retain their origin and are consistent with the principles defined in the Declaration of Helsinki

 

In Switzerland, ICH GCP E6(R3) Annex I came into force on the 15th of August 2025

What do I need to do?

As a SP-INV / Site-INV, conducting clinical studies with Medicinal Products and Transplant Products, your are required to:

  • Comply with ICH GCP guidelines
  • Provide proof of GCP training (i.e. relevant study staff may also require GCP training). 

 

ICH GCP E6 guidelines do not apply to Medical Device studies (i.e. ISO1455 standards apply).

 

In order to fulfil GCP requirements:

  • Attend a swissethics approved GCP course
  • Complete ICH GCP training course(s) based on whether you are a Site-INV or SP-INV
  • File individually issued GCP training certificates in the study TMF/ISF

 

Apart from ICH E8, ICH GCP E6 is read in conjunction with other study relevant ICH guidelines, such as:

  • E2A Clinical safety Data Management
  • E3 Structure and Content of Clinical Study Reports
  • E7 Studies in Support of Special Populations, Geriatrics
  • E9 Statistical Principles for Clinical Trials
  • E11 Clinical Investigation of Medicinal Products in the Paediatric Population

More

  • GCP guidelines are not mandatory for HRO studies, but are highly recommended
  • CTUs offer swissethics approved face-to-face GCP training courses, including GCP-refresher courses
  • GCP online training courses are available. Prior to signing-up ensure these courses are approved by swissethics
  • Only trainings certificates obtained after 01.01.2014 are considered valid
