ECRIN - European Clinical Research Infrastructure Network

International Clinical Trials Day (ICTD)

In 2005, ECRIN launched International Clinical Trials Day (ICTD) to commemorate the day when James Lind started his famous clinical trial on scurvy in 1747, May 20th, and laid the foundation for modern clinical research. Celebrated every year on or around May 20th, ICTD is an opportunity for research organisations, clinical research professionals, and the public to acknowledge the achievements that result from clinical research and to discuss various trial topics.

ECRIN’s annual celebration of ICTD brings together European and international stakeholders. Given its success, the conference has been replicated by some of ECRIN’s member/observer countries, who have now introduced their own national/international ICTD celebrations.

ICTD 2020 will take place on May 19th, 2020 in Berlin (Langenbeck-Virchow-Haus Berlin, Luisenstraße 58/59, 10117 Berlin, Germany). The topic will be (patient-)recruitment in clinical trials. More information will be available soon.
