OpenTrials launch - 10th Oct, World Health Summit, Berlin


We are excited to share the news with you that we will officially launch the beta version of OpenTrials - an open, linked database of publicly available data and documents on all clinical trials conducted - this Monday 10th October at the World Health Summit in Berlin.

We hope that OpenTrials will increase discoverability, facilitate research, help identify inconsistent data, enable audits on the availability and completeness of this information, support advocacy for better data, and drive standards around open data in evidence-based medicine.

The launch will take place at the ‘Fostering Open Science in Global Health’ workshop, with OpenTrials being represented by our Community Manager, Ben Meghreblian. The workshop will be a great opportunity to talk about the role of open data, open science, and generally how being open can bring improvements in medicine and beyond!

If you’ll be attending the conference or the workshop, we’d love to meet you – please do get in touch and let us know.

Just before the launch, on 8th Oct, we’re also running a Hack Day (sponsored by PLOS Medicine) to help people learn more about the data that powers OpenTrials, how it’s structured, and how to use our API to search the OpenTrials database.

For more information about both events see:

If you’re interested in evidence-based medicine and open data, you can get involved with OpenTrials in a number of ways - have a look:

Just to update you all, we have now successfully launched the beta version of OpenTrials: our full press release with further details on the launch is available here:

In addition, Dr. Ben Goldacre published a blog and video on why we are launching this prototype now, inviting you to give us feedback, let us know what is not working, what is confusing or what features you would like to see. The blog also includes a walkthrough video in which Ben Meghreblian explains how to use the OpenTrials platform.

Finally, we have also created a User Stories page at, where we share several examples of how the OpenTrials platform could be used around the world. If you have questions on how the database works, if there is something you would like to see, or if you would like to share your own testimonial of how you’ve used even this early version of OpenTrials, then do get in touch, either here on the Forum or through email at
