These pages are for:

  • Patients, carers, and members of the public who want to know more about clinical trials and who might want to participate in a trial or give input into the research process.
  • Researchers who are looking for help to actively involve patients, carers, and members of the public in their research.


They tell you more about:

  • Clinical trials: what is a clinical trial, how do they run, and how to take part.
  • Patient and Public Involvement (PPI): what is PPI, and how we are working to embed PPI in all our studies. We also share a useful list of PPI resources that we have created.


Read more about it in the sections below.  

About Clinical Trials

Clinical trials are research studies involving patients, which compare a new or different type of treatment with the best treatment currently available (if there is one).

Taking Part in a Clinical Trial

These pages tell you how you can find a trial to take part in and what questions you could ask, if you are invited to take part in a trial.

Patient and Public Involvement

These pages tell you what Patient and Public Involvement (PPI) is, and how it is being taken forward at the MRC Clinical Trials Unit at UCL.
