Your Partner for Clinical Trials in the UK

Want to volunteer for a paid clinical trial?

Before new medicines are given to patients, they must be tested in approved clinical trials. If you’re a healthy man or woman, aged 18 to 75, you can volunteer to take part in our paid clinical trials. So while you relax in our comfortable facilities, play on our PlayStations, watch the latest boxset on Netflix or the big match on Sky Sports, or even just catch up on sleep, you might help us find a treatment for a disease. Simple really, and we’ll pay you for taking part in our medical trial!

Are clinical trials safe?

The medicines we study are tested thoroughly before we give them to volunteers. All our paid clinical trials are reviewed by an independent ethics committee, who ensure that the information we give you is as full as possible and that our medical trials are ethical. A UK Government agency reviews them to make sure they are as safe as possible. Joining our trials not just gets you a handsome payout, but also helps us and our partners develop medicine that improves the quality of life for many patients worldwide.

Am I eligible to take part?

If you’re healthy and aged 18 to 75, you might be eligible to take part. We do medical trials in young and old people, petite or large, men and women, and smokers and non-smokers. We also do paid clinical trials in special groups like people with asthma or migraine. You won’t be able to take part if you’ve participated in another trial or given blood in the last 3 months, or have used recreational drugs, like cannabis, in the last 6 weeks. You must be registered with a GP and not take regular medication to be eligible for a medical trial.
