International Trial Master File Day:

27 May 2025 – Creation of the International Trial Master File (TMF) Day – 10th June
International Trial Master file was the brainchild of Sarah Hitching, founder of Hedian Records Management, who recognised that the TMF deserves its own celebratory day. A day for education, raising awareness and calling all trial team members to action to raise the priority of TMF filing. The day was launched on 27th May 2025 in a LinkedIn post by Sarah Hitching and subsequently  celebrated on the day in LinkedIn by Sarah Hitching, Karen Roy and Jamie Toth.

The date was inspired by the first time the term ‘Trial Master File’ was used officially in the guideline International Council for Harmonisation of Good Clinical Practice Revision 1 (ICH GCP E6 R1). The date of this publication is 10th June 1996 – the perfect day for International Trial Master File Day! This date in 2010, some 14 years later, is also the launch date of the TMF Reference Model Version 1 as you can see in the launch presentation.

This important awareness day is also noted  on Wikipedia at the bottom of the Trial Master File page.
