About psilocybin therapy

Psilocybin is a psychoactive substance and an active ingredient in so-called ‘magic mushrooms’. In our psilocybin therapy protocol, patients are given a dose of our synthesised psilocybin with psychological support from a therapist. This is preceded by, and followed up with, preparation and integration sessions.

A number of small academic studies have suggested that psilocybin therapy provides immediate and sustained reductions in depression and other health conditions, following a single treatment. The timeline below shows some of the key developments in psilocybin research in the last few decades.

We are running a clinical trial of psilocybin therapy for treatment-resistant depression. This will be the world’s largest psilocybin study to date, and is taking place in clinical trial sites across Europe and North America. For more information on our clinical trial, see ‘Our clinical trials’ below.

About treatment-resistant depression

‘Treatment-resistant depression’ (TRD) is a term used when people with depression do not respond adequately to anti-depressant medications within a set amount of time.

Definitions of treatment-resistant depression can vary. Many doctors diagnose their patients with TRD if they have tried at least two different types of anti-depressant medication without any improvement.

Depression is the leading cause of disability and ill health worldwide. Up to two-thirds of people with depression do not respond to the first antidepressant medication they try. Up to a third of people with depression do not respond to multiple attempts at treatment.

Our clinical trials

Treatment-resistant depression study

We are running a randomised controlled trial of psilocybin therapy for treatment-resistant depression. This will be the largest clinical study of its kind and is taking place in a number of clinical trial sites across Europe and North America.

I suffer with depression

Recruitment to this trial is managed directly by the research teams at our trial sites, who work with specific eligibility criteria. In particular, only people who have tried two, three or four anti-depressants without success in the last two years could be eligible to join – and this would need to be verified by your physician. If you think you might be eligible, please contact a study centre near you – locations are listed on the map below.

It may be possible to receive treatment at a site in a country other than that where you live, but this can be very complicated to organise and is up to the site to agree.  All applicants need to speak the national language of the country where the trial takes place. In addition, due to the number of face-to-face clinic visits required, applicants should ideally live within one to two hours of the site, unless special provisions have been made.


I am a clinician

Only people who have tried two, three or four anti-depressants without success in the last two years could be eligible for this trial. If single episode, it must be more than 3 months but less than 2 years. People interested in joining this trial who satisfy the below eligibility criteria need to be referred by their physician in order to be considered for the study. If you have a patient who may be suitable, please contact a study centre near you. Locations are listed on the map below, or visit ClinicalTrials.gov for a list of contact details.

Healthy volunteers study

In conjunction with the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London, we have completed a double-blind placebo-controlled phase I study with 89 healthy volunteers, aged between 18 and 65 years.

Initial results of the study were presented at the ACNP 2019 annual meeting with a poster. Click here to read our press release.

 

Expanded access policy

We are currently conducting a phase IIb clinical trial of psilocybin therapy for treatment-resistant depression. We will not have the required preliminary efficacy and safety data to make a benefit-risk analysis until the end of this phase, at the very earliest, and so our psilocybin is not yet available under compassionate use.

COMPASS Pathways’ position on offering compassionate use of investigational medicines

We conduct clinical trials to assess the safety and efficacy of investigational medicines which, if proven, will allow us to obtain the necessary approvals from regulatory authorities to provide patients with access to these medicines. We believe that participating in clinical trials is the best way for patients to access medicines prior to approval.

In some circumstances, when this is not possible, patients with diseases or conditions may seek special access to investigational medicines outside of a clinical trial setting. These situations are typically referred to as compassionate use, but can also be known as expanded access, early access, pre-approval access and emergency use.

Through the clinical development process, a drug is rigorously tested for safety and efficacy in humans; if proven, it is submitted to regulatory authorities for approval for sale, and then made available through healthcare systems to as many patients in need as possible, as quickly as possible. Because we do not know during the clinical development whether the investigational medicine is safe or effective, compassionate use may present risks for both the patient and the clinical development programme. For patients, compassionate use may bring potential safety risks or a false sense that the medicine will provide benefit; for the clinical development programme, it can delay or jeopardise the approval of a new medicine sought by many.

We are responsible for ensuring the quality and integrity of our clinical trials and for minimising any risks to participants and possible future patients. When considering compassionate use of an investigational medicine, we consider many factors, such as the strength of the clinical data, the benefit-risk profile, the impact on the clinical development programme, the phase of development, and the probability and timing of regulatory approval.

A compassionate use programme, or a single request for compassionate use of an investigational medicine, can only be considered if the following conditions are met:

• There are no adequate alternative therapies or clinical trials available

• Sufficient preliminary efficacy and safety data exist for the therapy to enable COMPASS Pathways to make a benefit-risk analysis consistent with the establishment of a compassionate use programme. This would not occur earlier than the end of Phase IIb studies, and depending on the clinical programme, potentially even later

• Sufficient clinical data is available to identify an appropriate dose

• A patient’s treating physician and COMPASS Pathways’ Head of Clinical Development both believe there is potential for the patient to reasonably expect benefit from the treatment, and there is robust evidence to support the possibility that the patient will benefit from it

• Adequate supply exists to support both the ongoing clinical trials and approved compassionate use, until and if the product becomes commercially available

• The patient is not eligible for any of the COMPASS-sponsored studies of the treatment. Geographic limitations to participation in a trial would typically not mean a patient is ineligible

• Compassionate access will not adversely impact the clinical development programme, in particular, the conduct of a pivotal clinical trial that is required for regulatory approval

• The request must be made by the patient’s treating physician, unsolicited by COMPASS Pathways or any other individual or organisation

COMPASS Pathways will use the above criteria in consideration of whether to offer compassionate use. We cannot, however, guarantee that a compassionate use programme will be offered, and if it is offered, that the investigational medicine will be available to a particular patient.

Any pre-approval access to an investigational product must always comply with the applicable country-specific laws and regulations, including medicine importation requirements, and approvals must be secured from relevant regulatory bodies and the Institutional Review Board or Ethics Committee of the treating hospital.

Investigator-initiated studies

We are keen to further research that will change mental health outcomes and help those who have not been helped by other treatments. To support this, we work in collaboration with select academic institutions and researchers around the world. We provide our cGMP (clinical Good Manufacturing Practice – the highest manufacturing grade) psilocybin to researchers free of charge, in exchange for the right to use safety data. Researchers are expected to cover packaging and shipping costs with our logistics provider.

For these investigator-instigated studies, we also provide support in protocol development through a project manager and input from our Scientific Advisory Board.

If you are interested in working with COMPASS through an investigator-instigated study, please contact us at info@compasspathways.com.

Partnerships

Collaboration is key to developing a new approach to mental health. We are bringing together digital health innovators, healthcare systems, payers, and others, for the benefit of patients.

Mindstrong Health delivers digital biomarkers of brain health. Its scientifically validated technology uses content-free, human-smartphone interactions to measure cognition and mood. We are working with Mindstrong Health on our treatment-resistant depression clinical trial to assess digital biomarkers as exploratory clinical endpoints.

Calm gives our therapists access to meditation content and training.

7Cups has developed a training bot which is used by our therapists to develop and practise their active listening skills.

Our pipeline

We are committed to developing new therapies that will help people suffering with mental health conditions and ease the burden on healthcare systems.

We are actively exploring additional indications for psilocybin and at least two new substances, with a goal of bringing these to market over the next 5-10 years.

Our goal is to accelerate patient access to evidence-based innovation. We are interested in any innovation that might help those for whom existing treatments don’t work, whether that involves psychedelic drugs or not.
