What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how psilocybin therapy can reduce anxiety and depression in cancer patients. It targets those with metastatic solid tumors or incurable blood cancers. The treatment combines psilocybin, which may alter brain activity and mood, with group therapy sessions. Individuals experiencing anxiety or depression related to their cancer and willing to participate in group therapy may be suitable for this study. As a Phase 2 trial, the research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to significant findings.

Do I need to stop taking my current medications for the trial?

You may need to stop taking certain medications, especially psychiatric medications, during the study. If you are on selective serotonin reuptake inhibitors (SSRIs) or other psychiatric medications, you should discuss this with the study team. Some medications, like MAOIs and tramadol, are not allowed, and you must avoid starting new psychiatric medications during the trial.

Is there any evidence suggesting that psilocybin therapy is likely to be safe for humans?

Research has shown that psilocybin therapy might be safe for treating anxiety and depression in cancer patients. In earlier studies, cancer patients who received psilocybin reported lower levels of depression and anxiety. For instance, one study found a 53% drop in depression severity based on patients' own ratings after receiving the treatment. These studies also suggest that patients generally tolerated psilocybin therapy well, with no serious side effects reported. Although researchers continue to study psilocybin, early results appear promising for its safety and effectiveness in helping cancer patients with anxiety and depression.12345

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for anxiety and depression in cancer patients, which often involve antidepressants and therapy, psilocybin therapy is derived from a psychedelic compound found in certain mushrooms. Psilocybin works by affecting serotonin receptors in the brain, potentially leading to profound shifts in mood and perception. Researchers are excited because this treatment could offer rapid and long-lasting relief, sometimes noticeable after just one session, which is significantly faster than traditional antidepressants. Additionally, the integration of group and individual therapy sessions enhances the therapeutic experience, helping patients process and integrate their experiences effectively.

What evidence suggests that psilocybin therapy might be an effective treatment for anxiety and depression in cancer patients?

Research has shown that psilocybin can help reduce anxiety and depression in cancer patients. In studies with these patients, psilocybin significantly lowered these symptoms. One study found that about 80% of patients felt better, with some experiencing complete relief from their depression. In this trial, participants will receive psilocybin therapy, which changes brain activity and helps improve mood. This treatment is used alongside therapy sessions to help patients better understand their situation. Early results suggest that this method is both safe and effective.12467
