FAQs on the conduct of clinical trials during the COVID-19 pandemic

latest update 22 February 2021


Sponsors, investigators and project managers of clinical studies and research projects in Switzerland must ensure that all studies are conducted in accordance with the COVID-19 Ordinance 3 of 19 June 2020 (as of 8 February 2021) of the Federal Council.

All decisions to adapt the conduct of clinical trials should be based on a risk assessment according to ICH GCP E6(R2) carried out by the sponsor and documented in the Trial Master File (TMF). The risk assessment must constantly be re-evaluated, documented and adapted to the evolving situation.

In case of doubt, the safety of study participants is of highest priority.
