Take part in clinical trials

Clinical trials are a vital step in making sure that new treatments reach patients. If you would like to take part in clinical trials, speak to your healthcare team about trials that may be suitable.

On this page we’ll cover:

What are clinical trials?

What are clinical trials?

Before searching for and talking about clinical trials, it can help to understand better what clinical trials are and how to decide if they could be the right thing for you. 

Clinical trials are used to test new treatments or research. They aim to find out whether the treatment will work as well the best ways of delivering it. They are also important for testing side effects.

Clinical trials could be helpful to you because they could give you access to a new treatment, which might benefit your journey. You would also be helping to advance treatment, which might help many more people.

How do I take part in clinical trials?

The best thing to do first is to talk to your healthcare team about why you wish to take part in clinical trials. 

Ideally, you should try to have this conversation with your consultant (e.g. your neurosurgeon or oncologist). We have some guidance on this here: 

  • Start the conversation as early as possible with your consultant. Your treatment may impact the trials you’re eligible for. 
  • Consider why you would like to participate in a trial and explain this to your doctor. 
  • Talk to your consultant about any trials you are interested in
  • Contact the Principal Investigator (lead researcher) for a trial you are interested in to find out if you may be eligible 
  • Ask your medical team for a referral to a trial that is suitable 
  • Ask for a second opinion or referral to a different specialist who can talk to you about trials. You can do this on the NHS or privately. 
  • Advocate for yourself or ask someone else to. Bring someone with you to the appointments where possible. 
  • Take notes or record the conversation, so that you can remember what was said and reflect back on this afterwards.

Are there clinical trials near me? And how do I find a suitable trial?

When searching for a clinical trial, there are a few things which it can help to look out for, to find out if it’s right for you.

Eligibility criteria – Clinical trials often have strict entry conditions which you must meet in order to take part. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). These criteria may include: 
·       your tumour type, grade and location
·       whether your tumour is newly diagnosed or recurrent 
·       the results of any biomarker testing 
·       any treatments you have had 
·       your age
·       other medical conditions you have or medications you are taking
It can help to make sure you know as much of this information as possible before you start looking for trials. 

Location – Knowing where the trial is taking place, whether this is in certain hospitals or online, can help you understand whether you’d be able to travel there easily.  
It may be useful to ask about help with the costs for travelling to and from the hospital for your clinical trial appointments.  
Phase – The phase of a clinical trial can help you understand more about it, such as how many people will be involved and the evidence behind the treatment so far.

Recruitment status –  this can help to understand how soon the trial will be available to take part in. Examples of what this status may be are: 
·       not yet recruiting 
·       recruiting  
·       active, not recruiting 
·       completed 

Trial design – In some trials, a group of patients will not be given the new treatment and are instead given the current standard treatment or a placebo. This allows a comparison with the group who are taking the treatment, so that the impact of the new treatment can be accurately determined. You may want to see whether this is the case for a trial you are looking at.
Cancer Research have some information on placebos and trial design  

It’s important to note that there are still benefits to being on a placebo within a trial. Read more about the benefits of being on a trial.  
If you are struggling to understand some of the terminology around trials, please get in touch with our Support team who will be happy to help.

Where can I search for clinical trials? 

Clinical trials take place globally and there are a number of different databases that you can search to see what is available.

While we are not able to recommend any specific platforms, we have included some information below on platforms which our community have found helpful. 

Please remember that clinical trials have strict eligibility criteria, which you must meet in order to join the trial.

If you find a trial that you think is suitable, you should speak to your doctor. 


MyTomorrows is a free international platform that helps patients and physicians to access drugs that are still in development.

Following an initial telephone interview with you, they will search for clinical trials and treatment options on your behalf and provide you with a comprehensive report listing their findings.

What can I do if I’m not able to take part in a clinical trial?

There may be several reasons why you may not be able to take in a trial. This can be difficult to accept, but it can help to know that there are other things you can consider.  

Ask about other treatment options. You can speak to your healthcare team about whether there are any other treatment options you can explore, such as emerging or alternative treatments.

Read our information on emerging treatments.

Tips from our community

“You should always advocate for yourself or your relative who may be going through this. Every single person is so different and in a particularly vulnerable time, it is easy to get weighed down with facts and figures you read on the internet or get told by your doctor. You don’t have to accept this: you do have the right for more.”

“Clinical trials always seem to scare people and doctors alike, but it doesn’t have to be this way. As long as you are equipped with every resource and option available to you, you know that you have explored your options wholeheartedly.”


This may not be easy. It can mean travelling to and staying near the site of the clinical trial. Sometimes a trial is geared to take patients from other regions. The best thing is to talk to your healthcare team to see if particular arrangements can be made. 

We have heard from our community that it can seem difficult to find a trial that they can take part in or that they have not heard about clinical trials before. There may be a number of reasons for this:

There are unfortunately not a huge number of clinical trials for brain tumours, meaning it is more difficult to find one that is right for you. This is something we are keen to change.

Read more about the research we fund.

The eligibility criteria for trials can be strict. There are several reasons for this: 

  • Eligibility criteria are important to ensure the trial has accurate results. By ensuring that trial participants have similar characteristics (e.g. tumour type), researchers will know that the results of the trial are because of the treatment being given and not a result of other factors. 
  • The eligibility criteria also ensure that people who could become more ill by participating in the study are not enrolled. 

If you do not meet the criteria you unfortunately won’t be able to join the trial. Most often, trials are aimed at people who are newly diagnosed with a brain tumour or who have had a recurrence. 

Trial locations vary across the UK and globally

Hospitals across the country have variable dedicated research staff and time. You may wish to consider other hospitals which it would be possible to travel to in order to receive treatment.  

Find out about choosing where to be treated.

While there may be trials available outside of the UK, in order to access these you would need to transfer your entire care to this country. Some people may also not be able to travel due to their diagnosis.
