Hear from participants

The entire team have been so welcoming, informative, attentive and kind throughout both trials. I've felt very safe and supported and able to freely share any queries or concerns. I feel fortunate to have had such a warm, structured and safe environment to journey through my own mind and learn how to better love, honour and accept myself. I've been liberated from many unhelpful, entrenched patterns and deep wounds now have the opportunity to heal. Thank you, team. It has truly been revolutionary!!

Trial participant, 2025

During this trial I have felt very well held and looked after by all staff involved with Clerkenwell Health who all seem committed to providing the highest level of patient care through every step of the way. [...] I was worried going into this that the setting and organisation would be too clinical and corporate but this couldn't have been further from the truth. Everybody has been so generous with their time, flexibility, reimbursement of ticket costs etc. I would strongly recommend this organisation to anyone interested in participating in clinical trials of this nature.

Trial participant, 2025

For so many who were lost in darkness, [Clerkenwell] has been a lifeline. Their groundbreaking work has changed countless lives for the better, mine included. I didn't realise how close to the sun I was Lying until the trial was complete. I owe them the rest of my life, my happiness and being reunited with my partner and son. I hope one day I see them in the headlines for helping others at scale like they have for me so I can show my son and say, these are the people who brought me back from the dead.

You have literally saved my life. I’m not exaggerating.

FAQ

FAQ

Common questions people ask before joining

Common questions people ask before joining

Is it safe to take part?

All our studies follow strict UK regulatory guidelines. Every trial is reviewed by ethics committees and led by psychiatrists, therapists and nurses experienced in mental health care. You'll be carefully screened, supported throughout and can stop at any time.

What if I change my mind?

You can withdraw at any point - before, during or after the trial - with no questions asked. Your wellbeing comes first, always.

Do I have to pay or will I be paid?

You'll never pay to take part. In many cases, we cover travel and related expenses. Some trials offer modest compensation for your time.

Can I continue my current medications?

When you take part in a clinical trial, it is important that you continue to take all the medications that are advised by your healthcare provider. Certain medications cannot be taken at the same time as the treatments we are testing in our trials and may affect whether you can take part. In some cases, you may still be able to take part but this will be discussed fully with you as part of our screening process.

Will psychedelic treatments help me?

If you take part in a psychedelic-assisted psychotherapy trial you will be offered therapy and a psychedelic or a dummy drug. Therapy on its own can be helpful. Psychedelics have the potential to make therapy work better, but we don't know for sure yet.

Am I eligible to take part?

Researchers call the entry conditions for trials 'eligibility criteria'. Trials have these to make sure that the patients taking part in a trial are as similar as possible. That way, if one group does better than the other, researchers can be sure it was due to a difference in treatment and not due to their condition being more or less severe.

Eligibility criteria are clearly written in trial protocols. Examples where there are clear guidelines around eligibility could be age or the types of medication you are on or the diagnosis that you have. Eligibility criteria change for all trials so while you may not be eligible for one trial you may be for another.

How will I know if I'm eligible after I register?

After you complete the short form, our clinical team reviews your details. If you're a potential fit, we'll invite you for a screening call and health check to confirm eligibility.

When do clinical trials start?

We run new studies throughout the year. Once you register, we'll keep you updated when a suitable trial opens near you.

Where do clinical trials take place?

Our clinics are located in central London and Doncaster, with more sites launching soon.

Which conditions are researched?

We focus on neuro and psychiatric conditions.

Psychiatry: Depression, PTSD, Anxiety Disorders, Eating Disorders, Substance Use Disorders, ADHD, and Autism Spectrum Disorder.

Neurology: Pain, Migraine, Parkinson's Disease, Alzheimer's Disease, and Dementia.
