What is the purpose of this trial?

This trial tests the effects of microdoses of psilocybin, a compound in certain mushrooms, to determine if it can help individuals who feel hopeless or have lost meaning in life. Researchers aim to discover if small doses can provide benefits without causing strong hallucinations or other effects that disrupt daily life. Participants will receive varying doses or a placebo once a week for five weeks. This trial suits English-speaking adults who have felt demoralized and have not used hallucinogens in three years. Participants should be in generally good health and able to arrange transportation after sessions. As an Early Phase 1 trial, this study focuses on understanding how psilocybin works in people, offering participants the opportunity to be among the first to receive this innovative treatment.

Will I have to stop taking my current medications?

Yes, you will need to stop taking certain medications, including those for ADHD, anxiety, depression, mood stabilization, and any with serotonin activity, as they are part of the exclusion criteria for this trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that psilocybin, a substance found in certain mushrooms, has generally been well-tolerated in past studies. In one study, participants took psilocybin in a single session with psychological support, and most found it acceptable. Some short-term side effects, such as anxiety, nausea, and increased blood pressure, have been reported, but these effects usually don't last long. It's important to note that while researchers are studying psilocybin for its potential benefits, limited information exists about its long-term safety. More research is needed to fully understand its long-term effects. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for demoralization?

Researchers are excited about psilocybin for treating demoralization because it offers a unique approach compared to traditional treatments like antidepressants or psychotherapy. While most conventional treatments focus on altering neurotransmitter levels or cognitive patterns over weeks or months, psilocybin, a psychedelic compound, may produce rapid and profound changes in perception and mood. It targets serotonin receptors in the brain, potentially leading to transformative experiences that redefine personal meaning and emotional outlook. The potential for psilocybin to provide fast-acting and long-lasting relief with minimal doses makes it a promising alternative for those who haven't responded well to existing therapies.

What evidence suggests that this trial's treatments could be effective for demoralization?

Research has shown that psilocybin can help reduce anxiety and distress. One study found that it significantly lowered anxiety symptoms just one day after treatment, with effects lasting up to six months. Another study revealed that psilocybin-assisted therapy helped people with serious illnesses feel less demoralized and distressed. Additionally, 75% of participants responded positively to psilocybin, with 58% experiencing complete relief from symptoms over a year. These findings suggest that psilocybin may help with feelings of hopelessness and lack of meaning, common in demoralization. Participants in this trial will receive varying doses of psilocybin or a placebo to evaluate its effectiveness in treating demoralization. ^{1 2 6 7 8}

Participants in this arm will receive 5 mg psilocybin once per week for 5 weeks.

Group II: 2.5 mg psilocybin Experimental Treatment 1 Intervention

Participants in this arm will receive 2.5 mg psilocybin once per week for 5 weeks.

Group III: 1 mg psilocybin Experimental Treatment 1 Intervention

Participants in this arm will receive 1 mg psilocybin once per week for 5 weeks.

Group IV: Placebo (0 mg psilocybin) Placebo Group 1 Intervention

Participants in this arm will receive 0 mg of psilocybin once per week for 5 weeks.

Published Research Related to This Trial

Psilocybin, a prodrug for psilocin, shows strong agonist activity at the serotonin 5-HT2A receptor, which is responsible for its psychedelic effects, and has been shown to have nanomolar affinity for various serotonin receptor subtypes in both in vitro and in vivo studies.

In mouse experiments, psilocybin and related compounds induced head twitch responses, a sign of psychedelic activity, which were blocked by a 5-HT2A antagonist, confirming the involvement of this receptor in their effects.

Psilocybin is primarily a pro-drug that converts to the active compound psilocin in the body, which then interacts with serotonin receptors to produce its hallucinogenic effects.

The metabolism of psilocybin and psilocin varies significantly among individuals, affecting their dose-response and potential toxicity, highlighting the need for personalized approaches in therapeutic settings.

In a survey of 1993 individuals who experienced challenging psilocybin trips, 39% rated their experience as one of the most difficult of their lives, with 11% reporting risks of physical harm, particularly influenced by dose and lack of support.

Despite the challenges, 84% of respondents felt they benefited from the experience, suggesting that while adverse effects can occur, the overall incidence of serious psychological distress is low, especially in controlled settings.

This study identified phenylethylamine in Psilocybe semilanceata mushrooms, which may contribute to adverse reactions during psilocybin intoxication, as evidenced by a case involving three young men who experienced severe symptoms.

The levels of phenylethylamine in these mushrooms can vary significantly, with the highest concentration found in the case of hospitalization, suggesting that this compound could play a role in the tachycardia and other symptoms not directly linked to psilocybin.

This study found that the binding of serotonin 2A receptors (5-HT2AR) in the brain can predict how long the peak effects of psilocybin last and how quickly individuals return to normal consciousness after its effects wear off.

Higher levels of 5-HT2AR binding were associated with lower scores on the Mystical Experience Questionnaire, suggesting that individual differences in receptor availability may influence the subjective experience of psilocybin, which could have implications for its therapeutic use.

The study successfully utilized GLC-mass spectrometry to analyze psilocin and psilocybin, two hallucinogenic compounds, by converting them into trimethylsilyl derivatives for better detection.

This method was specifically applied to an extract of the Psilocybe cubensis mushroom, indicating its potential for accurately identifying and quantifying these psychoactive substances in natural samples.

Psilocybin, a hallucinogenic compound found in certain mushrooms, has been associated with increasing rates of drug abuse, highlighting the need for comprehensive pharmacological understanding.

Despite its historical use in the 1960s for experimental medical purposes, recent research has only begun to uncover the pharmacological properties of psilocybin, indicating a gap in knowledge that needs to be addressed.

Psilocybin shows promising effects in alleviating anxiety, depression, and emotional distress in palliative care patients, with a favorable safety profile, based on recent studies and reports.

Despite its potential benefits, psilocybin is not yet approved for therapeutic use in the U.S., and significant barriers exist for access, particularly for vulnerable populations like the elderly and those in palliative care.

Psilocybin, a serotonergic psychedelic, has shown promise in treating various psychiatric disorders, including depression and substance use disorders, with 9 clinical trials conducted between 2000 and 2020.

The treatment is generally well tolerated with limited side effects, and some patients with treatment-resistant conditions have experienced significant long-term improvements after just a few sessions, indicating its potential efficacy.
