Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to evaluate whether psilocybin therapy can effectively treat depression and psychological distress in adult patients with COPD, ALS, MS, or APD who have at least 6 months life expectancy. The main questions it aims to answer are:

* Can psilocybin therapy safely reduce depressive symptoms compared to low-dose control?
* Will the therapeutic effects be rapid and sustained over a 6-month period?

Researchers will compare patients receiving two escalating doses of psilocybin (15mg followed by 25mg) against those receiving two low doses (1mg) to see if the higher doses lead to greater improvements in depression, anxiety, demoralization, and quality of life.

Participants will:

* Attend three preparation sessions with psychotherapists (1-2 hours each)
* Undergo two supervised psilocybin dosing sessions (6-8 hours each)
* Complete five integration therapy sessions following the dosing sessions
* Participate in follow-up assessments at 6 weeks, 3 months, and 6 months
* Have access to a digital care platform and peer support groups during the 6-month follow-up period
* Optional: Control group participants may receive one high-dose psilocybin session (25mg) after the initial study period

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rationale Patients with chronic obstructive pulmonary disorder (COPD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), or atypical and advanced Parkinsonian disorder (APD) often suffer from severe psychological distress with demoralization and death anxiety, which may culminate in to depressive disorder. Treatments of depression in palliative care currently involves psychotherapy and/or the use of antidepressants. However, these treatments have shown limited efficacy which urgently calls for new and innovative approaches. In recent years, a number of studies have shown very promising results of psilocybin therapy in alleviating psychological distress in patients with advanced cancer. The current study (PsyPal) aims to evaluate whether psilocybin therapy can also lead to rapid and sustained decreases in depressive symptoms, demoralization and other facets of psychological distress in patients who suffer from COPD, ALS, MS and APD.

Objective The primary objective of the PsyPal study is to assess the safety and efficacy of psilocybin therapy compared to low-dose control in reducing depressive symptoms in patients with COPD, ALS, MS, or APD. Secondary objectives of PsyPal are to assess change in clinical functioning, end-of-life anxiety, psychological/existential distress, health-related quality of life, and how it impacts caregiver 's health- and economic burden. The safety objective of PsyPal is to evaluate the difference in adverse events between high and low dose groups before, during and after the dosing session. Exploratory objectives include the investigation of psychological mechanism, subjective effects, biomarkers (EEG and blood-based), cost-effectiveness, and the usefulness of a digital care platform, with a mixed methods approach.

Main trial endpoints The main trial endpoint for PsyPal is the change in depression severity from baseline to 6 weeks after the second dose of psilocybin (high dose session). Adverse events and change in depression symptoms will also be assessed at 3- and 6-month follow-up to determine the safety and sustained effects of psilocybin therapy.

Secondary trial endpoints Secondary trial endpoints will be assessed at baseline and 6 weeks after the second dose of psilocybin. These include response rate, anxiety, demoralization, health-related quality of life, experiential avoidance, coping with illness, death anxiety, the wish to hasten death, self-compassion, spirituality, attachment, pain, healthcare resource use, blood-based biomarkers, and functional brain changes. Some secondary endpoints will also be assessed at the 3- and 6-month follow-up, including anxiety, demoralization, health-related quality of life, experiential avoidance, and coping with illness. These endpoints aim to improve our understanding of the effects of psilocybin therapy, how psilocybin therapy works, and to see which patients show the best response. Finally, changes in (religious/spiritual) beliefs/understandings and the experience(s) with psilocybin therapy will be assessed through in-depth qualitative interviews with patients that are conducted 6 weeks after the second dose of psilocybin.

Trial design PsyPal trial consists of a double-blind randomized low-dose controlled clinical trial with long term follow-up. Patients who are enrolled in the trial will be actively participating for ten weeks. After the primary endpoint, patients who received a low dose of psilocybin (1 mg) will be offered an optional single open label high-dose of psilocybin (25mg) together with three integration sessions. During long-term follow-up, patients will have access to a digital care platform and peer support groups.

Trial population The trial population in PsyPal consists of patients with COPD, ALS, MS, or APD and co-morbid depression. The main further inclusion criteria for participation are an age of 18 or higher, having an identified caregiver or support person, and a life expectancy of at least 6 months. The main exclusion criteria are current use of antipsychotic drugs, suicidal ideations, schizophrenia or other psychotic disorders, bipolar I/II disorder, other major neurological conditions, cardiovascular conditions, diabetes, and/or moderate to severe hepatic impairment (i.e., liver failure). Other exclusion criteria are a first-degree relative on the schizophrenia spectrum, other psychotic disorders, or bipolar I disorder.

Interventions

Patients will receive psilocybin therapy consisting of three phases; 1) preparation, 2) dosing, and 3) integration:

Preparation - The preparation phase consists of three psychotherapy sessions of 1-2 hours each. The purpose of these sessions is threefold: to build a therapeutic alliance between the patient and the therapist, to make a psychotherapeutic treatment plan for the patient using a process-based approach, and to educate patients about psilocybin's acute effects and how patients and therapists together can handle difficult experiences during the dosing sessions.

Dosing - The dosing phase of PsyPal starts 1-3 days after the last preparation session. It consists of two escalating dosing sessions of 6-8 hours each. The patient first receives a moderate dose of psilocybin (15mg). Two weeks later, the patient receives a high dose of psilocybin (25mg). Patients in the control group will receive two doses of psilocybin (1mg). All dosing sessions take place under supervision of two trained therapists within a treatment room specifically designed for psilocybin therapy and with a medical doctor on call.

Integration - The integration phase consists of five psychotherapeutic sessions of 1-2 hours each. There are two integration sessions following the first dosing session and three integration sessions following the second dosing session. The integration sessions are intended for further psychotherapeutic work, including working with the experience(s) that may have emerged during dosing sessions, and clinical assessment of the patient. Central topics may include the relationship with their life-limiting illness, death, meaning, sense of purpose, personal (religious/spiritual) beliefs, (social) relationships, and conflict resolution. The patient can also share thoughts and feelings about the PsyPal trial.

Long-term follow-up After the intervention, patients will be returned to regular care and followed for a period of 6 months, tracking usage of healthcare resources, the digital care platform, and peer support groups. Qualitative aspects of the intervention will be evaluated for patients, caregivers and therapists. Long-term safety data of psilocybin therapy will be collected for the four patient populations.
