Potential benefits of 
joining the RADIAL trial

Recruitment closed

Deciding to join the RADIAL trial could have a number of potential benefits:

Close, regular, medical attention within a structured plan

Being in a clinical trial creates a new structure in your life where you will have a clear set of personal responsibilities and frequent contact with healthcare professionals. It has been shown that being in a clinical trial (regardless of the medication that is provided) can improve glucose management, presumably because trial participants get more medical attention than usual and begin to feel empowered and supported to make changes in their self-care.1,2

Opportunity to switch your long-acting basal insulin

Your current long-acting insulin will be switched to the long-acting insulin, Toujeo®, which may help you improve your blood glucose management. You may also join the trial when you are already using Toujeo® as your current long-acting basal insulin.

Some published studies have shown Toujeo® to have advantages among long-acting basal insulins in terms of keeping glucose levels stable and reducing the risk of hypos 3,4,5,6. You’ll be given clear guidance on how to adjust the dose of Toujeo® yourself, which will put you in control of your glucose management. When the trial is over, you can talk to your own doctor about prescribing Toujeo® for you, if you’d like to continue with it.

Opportunity to try new healthcare technology

All participants who take part from their home will use the latest technology. This will include video calls with the trial doctor, a ‘smart’ cap for your insulin pen – which automatically captures the dose, date and time of each injection – and a connected glucometer, which automatically transmits your blood glucose readings to your trial apps and the research team.

Opportunity to be a research pioneer

Alongside the potential personal benefits, joining the RADIAL trial means you will be helping to shape the future of clinical trials. This in turn could accelerate medical progress. Because decentralised (home-based) trials have the potential to make clinical research in general more convenient and more accessible for participants, it is likely that more people will decide to take part in future research. So, your efforts to focus on your own health as a RADIAL participant will also make you a research pioneer.

RADIAL trial timeline (decentralised group)

The RADIAL trial will last for about 7½ months. The first six weeks will be the screening phase where the research team will make certain the trial is suitable for you. You will continue on your current long-acting basal insulin during this period.

The main treatment period of the trial – where you will receive Toujeo® – will last for 6 months (24 weeks), with three scheduled video calls with the trial doctor. 

You’ll be self-injecting Toujeo® once a day using a disposable injection pen and ultra-fine needle. Your Toujeo® pen cap will automatically record the dose, date and time each time you inject.

What you’ll need to do if you join the RADIAL trial 

Testing your blood glucose regularly is a very important part of the RADIAL trial. This will be done by pricking your finger with a sterilised lancet and using a 'smart' glucometer that will automatically transfer blood glucose readings to your trial apps.

You will need to do this every morning during the time taken to find the most appropriate dose of Toujeo® and after that, three times a week.  You should also do it if you suspect a hypo may be happening. 

The thought of finger-pricking on a daily basis may be worrying or unappealing at first, but most people become accustomed to it fairly quickly.

Doing this is vital as it guides adjustment of your insulin dose and helps you gain the most benefit from it. 

On three occasions, you will also need to provide a few drops of blood from your finger for measuring your HbA1c level (a measure of your average blood glucose over time). You will be given additional instructions on how to do this and how to send the sample to the research team.

What other trial responsibilities will you have?
What medical support will be provided?
What will happen after the trial?
What equipment will you need for the trial?
What training and support will be provided?

You will need to download two trial apps. These will set up automatic recording of your blood glucose readings and dosages/times of Toujeo® injections and provide access to an electronic diary (e-diary) where you’ll be able to record important trial data, join scheduled video calls with the trial doctor, receive reminders and messages, and contact the research team.

Both apps used in the trial are secure, virus-free and will respect your privacy.

Help and support with the technology will be available from the research team whenever you may need it.
