Good Clinical Trials Collaborative

Randomised clinical trials are essential to advancing evidence-based medicine and improving human health. But new guidance is needed, which is why we've launched the Good Clinical Trials Collaborative.

Our position 

Results from well-designed randomised clinical trials tell us the difference between a promising medical intervention and a proven treatment. Their results inform patient care and public health. 

Researchers running clinical trials must comply with a complex system of regulations and guidelines that aim to reduce risk, provide clarity and standardise approaches. 

However, the over-interpretation of confusing or outdated guidelines has driven up costs through waste, delay and failure, and reduced the availability of proven and affordable treatments for many important health conditions. 

New guidance is needed to support a more effective regulatory environment for clinical trials – enabling more informative, ethical and efficient trials to improve patient care. 

What we're doing 

Launched in June 2020, the Good Clinical Trials Collaborative, supported by Wellcome, the Gates Foundation and the African Academy of Sciences, are reviewing the principles of randomised clinical trials for all types of healthcare interventions, in all settings. 

The new guidance will: 

  • be grounded in scientific principles
  • be easy to understand 
  • be proportionate and flexible 
  • be generalisable  
  • promote critical thinking and innovation. 

How we're shaping the guidance 

To inform the new guidance, we have:

  • run a survey to hear from researchers whose trials had been impacted by the Covid-19 pandemic. The aim was to capture the innovative practices that have enabled some trials to continue and the challenges that have affected others. 
  • consulted with a range of stakeholders, including clinical trial volunteers in Africa, Asia and Latin America, representatives of patient groups in Europe and North America, and more than 100 multidisciplinary experts.    

The survey report and draft guidance will be published in June 2021, followed by a public consultation period.

The Collaborative will publish the final guidance in autumn 2021.  

Our team 

The team is based at Wellcome and led by Professor Martin Landray, Nuffield Department of Population Health, University of Oxford. 

Our steering group  gives strategic advice to shape the work of the Collaborative.
