Psychedelic drugs are a class of psychoactive substances that alter a person's perception, thoughts, and feelings. Examples of psychedelics include LSD, psilocybin (found in magic mushrooms), and DMT, which we study in our trials to treat conditions such as depression, post-traumatic stress disorder (PTSD) or adjustment disorder.

Psychedelic clinical trials are research studies that investigate the safety and effectiveness of psychedelic substances as a treatment for various mental health conditions. These trials are conducted in a controlled, clinical setting under the guidance of trained healthcare professionals on either healthy volunteers or patients.

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.

Our team will notify you if you meet the eligibility criteria for a trial based on the information you give us. That means it's important to keep your details up to date on the registration platform.

If you subscribe to our mailing list above we will notify you when we have a new trial.

Most clinical trials take place in major cities in the UK.

We do not focus on a specific condition and carry out clinical trials for any condition our clients are interested in studying. This includes mental health conditions as well as CNS disorders.

We do not focus on a specific drug and carry out clinical trials for any psychedelic drug our clients are interested in studying. This includes psilocybin, LSD, MDMA, and 5-MeO-DMT among others.

All of our clinical trials are different so your involvement will vary depending on which trial you take part in. Some trials may involve multiple visits over a long period (in excess of 1 year) and on rare occasions may also require an overnight stay at one of our clinical facilities. Most of the trials we run at Clerkenwell Health will require you to attend a series of therapy sessions alongside a day or two of drug dosing over the course of 2 - 3 months. You will be made fully aware of what taking part will involve before you decide to take part in any of our studies.

You may receive financial compensation for your time and be reimbursed for travel expenses if you take part in a clinical trial.

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.

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.
