We’re building a UK-wide site network of purpose-built sites dedicated to CNS and psychiatric trials and designed around people, not processes.
Because when every site in your network is purpose-built for CNS research and operated by people who see patients as humans, not data points, extraordinary results become the standard.

Faster and more representative patient recruitment
Unmatched operational consistency
Fast-tracked site selection, set up and trial initiation
Single point of contracting

Doncaster | In partnership with RDaSH NHS Foundation Trust
An NHS-embedded model designed with patient access, commercial timelines, and NHS infrastructure seamlessly built in.
Our Doncaster site is the UK’s first-ever NHS-private partnership focused on CNS and mental health research. Developed in collaboration with Rotherham Doncaster and South Humber NHS Foundation Trust (RDaSH), the site is embedded in NHS infrastructure while operated by Clerkenwell Health - combining the trust and reach of the NHS with the delivery strength of a specialised commercial trials provider.
Why Doncaster
Located in a region often underserved by clinical research, Doncaster provides a valuable opportunity to engage a diverse, non-London patient population - supporting research goals around inclusion and representation. The site also contributes to regional capacity building by revitalising unused NHS facilities and training local NHS staff in advanced research delivery.
Why NHS Partnership
By embedding trials within real-world NHS care settings, this model removes many of the traditional barriers in UK research - enabling faster start-up, smoother recruitment, and greater patient trust. Sponsors benefit from NHS alignment without operational complexity, supported by Clerkenwell’s full-service delivery model.
Capacity
The site features:
8 dosing and screening rooms
Refreshed pharmacy with Schedule 1 capabilities
Licensed for controlled drug trials
Staffed in collaboration with local NHS clinicians
Linked to Clerkenwell’s central patient recruitment and quality infrastructure
