On the 2nd of August 2021 EMA published the start of the countdown to go-live for the Clinical Trials Information System (CTIS) (1). The countdown comprises 6 months and will end on 31 January 2022. As the application of the Clinical Trials Regulation depended on the confirmation of functionality of the clinical trial EU portal and database (one of the key components of CTIS) this confirmation has been long awaited. After announcing the CTR on 16 June 2014 the expectation was that CTIS would be available in December 2015. However, due to technical difficulties the “portal’s go-live date” was delayed several times over the past years, but was now confirmed on 31 July 2021.
