Understanding Music and Mindfulness Preferences in Psilocybin-Assisted Psychotherapy

Starting soon · Phase 2

Conditions studied: Treatment-Resistant Major Depressive Disorder

In brief

The goal of this pilot clinical trial is to learn whether it is feasible to individually tailor psilocybin-assisted psychotherapy (PAP) for people with treatment-resistant depression (TRD) based on their personal preferences. The study also aims to explore whether two different psychotherapy styles, music-centered and mindfulness-centered, influence how people respond to psilocybin treatment. The main questions it aims to answer are: * Is it feasible to conduct a patient-preference randomized trial of psilocybin-assisted psychotherapy? * Does receiving a preferred psychotherapy style improve treatment experiences or outcomes? * How do music-centered and mindfulness-centered PAP approaches compare in their effects on improving mood and well-being? Researchers will compare music-centered PAP to mindfulness-centered PAP to see if aligning psychotherapy with individual preferences is a practical and potentially beneficial approach for improving treatment efficacy and tolerability. Participants will: * Be adults with treatment-resistant depression * Receive two 25 mg psilocybin (PEX010, Filament Health) sessions, spaced four weeks apart * Experience one session with music-centered psychotherapy and one with mindfulness-centered psychotherapy * Before treatment, rate their preference for the two psychotherapy approaches * Be randomly assigned to receive their preferred or non-preferred approach first, followed by the other * Complete preparation and integration sessions before and after each psilocybin session This feasibility trial will also collect information on participants' cultural and personal factors influencing psychotherapy preferences using a modified Cultural Formulation Interview, and explore physiological measures of therapeutic alliance, an important factor in psychotherapy outcomes.

You may not qualify if…

• Deemed to be greater than low risk of suicide on psychiatric interview.
• Currently or previously diagnosed with any of the following, according to available information and psychiatric interview: major depression with psychotic features, schizophrenia spectrum or other psychotic disorders, and/or bipolar affective disorder I or related disorders.
• Current or past diagnosis of personality disorder deemed to pose a significant risk for safety and/or trial compliance.

• Deemed to be greater than low risk of future substance use disorder.
• Currently receiving and deemed to be unsuitable, on psychiatric interview, to discontinue medications with significant serotonin 2A antagonism (e.g., trazodone) or known potential for serious interactions with psilocybin including serotonin syndrome (e.g., monoamine oxidase inhibitors), seizures (e.g., lithium), or which may affect psilocybin pharmacokinetics (e.g. UDG modulators, aldehyde dehydrogenase inhibitors).
• Unwilling or unable to maintain current psychotropic medications throughout the treatment phase of the trial.
• Currently undergoing psychotherapy that will not remain stable for the duration of the study or was initiated within 21 days of baseline.
• Prior use of serotonergic psychedelics in the past year and/or more than five life-time uses.
• Use of any serotonergic psychedelic or ketamine, or any other illicit substance during the active treatment period of the trial.
• Medical contraindications:
• Current or past history of seizure disorder with the exception of infantile febrile seizures.
• Significant cardiovascular disease including uncontrolled blood pressure (> 140/90mmHg), clinically significant arrhythmia, heart failure, coronary artery disease, history of ischemic or hemorrhagic stroke, or history of myocardial infarction.
• Abnormal and clinically significant results on the physical examination, laboratory investigations, or ECG at screening.

• Pregnant or lactating.
• For women of child-bearing potential, defined as all women physiologically capable of becoming pregnant: unwilling to utilize highly effective contraceptive during the 10-week active intervention (e.g., oral contraceptive). Acceptable forms of highly effective contraception methods include: a. Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception; b. Male/female sterilization defined as: 1) Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed and documented by follow up hormone level assessment; 2) Male sterilization of the sole partner (at least 6 months prior to screening) of a female patient on the study. c. A combination of any two of the following (i+ii or i+iii or ii+iii):
• i) Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository ii) Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception iii) Placement of an intrauterine device (IUD) or intrauterine system (IUS).
