International Clinical Trials Day (ICTD) 2021

Platform trials: shift in testing, treatment & collaboration.

Due to the Covid-19 pandemic, ECRIN organised ICTD 2021 as an online, virtual event on May 20th, 2021. ICTD 2021 brought together stakeholders from across Europe and the globe to discuss the growing interest in platform trials from best practices to challenges in the European context.


About platform trials

ICTD 2021 bannerPlatform trials, sometimes known as adaptive platform trials, allow a multitude of different treatment options (arms) to be compared with a single control arm. They enable ineffective arms to be stopped after an interim analysis. To date, they have been used principally in the field of oncology and more recently infectious diseases. They represent the clinical approach selected by the European Commission to find a treatment for COVID-19.

This new trial format raises many questions, changes our approach to conducting clinical trials and testing for appropriate treatments. Through this online conference, we hope to help answering some of the following questions:

  • What are the underlying objectives of a platform trial?
  • Which parameters must be considered in the design, statistical plan and data management?
  • How should one address regulatory and ethical issues as well as the involvement of patients?
  • What types of management, economic and governance concerns may be encountered when we use this trial model?
