30 years’ clinical trial experience

Quotient Sciences are world experts in running clinical trials, supporting medical advancements and making them simpler for sufferers to take. All new test medicines undergo rigorous testing before they can be prescribed or sold and the clinical trials we run are part of this process.

We have 28 years’ experience operating clinical trials, during which time we have been involved in the development of medicines for many key health issues facing the UK today and have developed specialist knowledge in developing once-a-day medicines and inhaled medicines.

Every day, our nurses evaluate and monitor the health of our volunteers

Ensuring your safety and well-being

Our state-of-the-art clinical unit is based in Ruddington, just outside Nottingham, and features the highest quality facilities and equipment, ensuring your stay is as relaxing and enjoyable as possible.

Your safety and well-being is our primary concern and we have highly qualified staff, including doctors, nurses and technicians at our unit 24 hours a day. We are approved and regulated by the MHRA (Medicines and Healthcare products Regulatory Agency), who approve and monitor all clinical trials in the UK. The MHRA also regularly reviews every detail of how we run our trials to ensure the safety and comfort of our volunteers. An independent ethics committee also reviews each trial that we conduct before it begins.

This ensures that we continuously deliver an independent and volunteer-centric view of our processes and documentation, through feedback and open forums.Volunteer centricity
