Your trusted partner for accelerating psychiatric and CNS research through innovative clinical trial design and delivery.

We design and deliver clinical trials on time and within budget, with optimised outcomes.


Clerkenwell Health is closing a critical gap in the clinical trial landscape, specialising in psychiatry and CNS—fields experiencing rapid growth and requiring expertise to deliver on time and budget. Despite this surge in research, specialised trial sites outside the US are limited. We’re on a path to becoming the European leader by building a scalable network of clinical trial sites and CRO-enabling services.

We’re leading the future of clinical research


Our forward-thinking operating model combines the operational consistency and resource access of site networks with the centralised services and oversight of a CRO, setting a new benchmark for trial design and delivery. We’re not just adapting to the future—we’re shaping it.

Integrated trial design and delivery


Our fully integrated model brings a new level of operational sophistication to complex clinical trials. By combining CRO services, trial sites, and advanced supporting technologies, we create valuable synergies that drive both efficiency and precision in trial execution.

With a single point of contracting for multiple sites and principal investigators, we streamline operations while maintaining tight control over trial design and delivery. This integrated approach ensures that trials are not only practical to run but also tailored to optimise the patient experience. By sharing workforce, standardised processes, and technology across all functions, we can design trials that are more efficient, patient-friendly, and deliver better clinical outcomes.

Reliable and efficient patient engagement


We take a patient-centric approach to recruitment and trial delivery, drawing from our extensive experience in mental health care and research. Our focus is on enhancing participant experience from initial contact through to trial completion.

Our multi-channel, adaptable recruitment strategy allows us to rapidly identify and screen participants using the most cost-effective methods. Alongside our highly engaged patient database, we maintain close partnerships with referral sources including patient groups, charities, hospitals, and a trusted network of clinicians and therapists. This model enables us to build a participant pipeline pre-approval and add sites without needing additional regulatory approval.

Network of principal investigators and therapists


We’ve built a robust network of principal investigators with extensive experience and a ready-to-deploy pool of therapists trained to the highest standards. With this foundation, we can swiftly assemble the right team to meet the unique demands of your trials.

Recognising the critical role psychological intervention plays in the success of psychedelic trials, we've developed a specialised psychedelic practitioner training program. This program, combined with our rigorous monitoring process, ensures that therapy is delivered consistently across all sites and by all practitioners, safeguarding the integrity and reliability of your trial results.

Deep expertise in psychiatry & CNS


In psychiatric and CNS research, a one-size-fits-all approach simply doesn’t work. Generalist CROs often rely on standardised, "cookie-cutter" models that overlook the critical nuances of thse patient populations. At our core, we understand that patients face unique challenges, and we’ve built our expertise around addressing these needs with precision and care.

Designing practical and easily deliverable studies requires a deep understanding of both the science and the patient journey. Our experience allows us to develop study designs that not only meet regulatory standards but also optimise the patient experience to ensure recruitment and retention.
