NCT07211438

Evaluating the Role of Psilocybin Monitors in Psilocybin Therapy for Treatment Resistant Depression

Psilocybin, the chemical component of "magic mushrooms", has been administered with psychological support in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. The purpose of this study is to determine the role of psilocybin monitors on the effects of psilocybin therapy in adults with treatment resistant depression.

Ultrasound Neuromodulation of Circuits and Negative Valence Systems in Treatment-Resistant Depression

Approximately one third of individuals with Major Depressive Disorder (MDD) are considered treatment-resistant, subject to severe disability and risk of suicide, and exhibit symptoms anchored in abnormalities of Research Domain Criteria (RDoC) Negative Valence Systems behavioral processes. In the present study we plan to use low-intensity focused ultrasound in 120 persons with treatment-resistant MDD to modulate deep white matter tracts connecting the thalamus and different regions of the prefrontal cortex reversibly and non-invasively, with the aim of assigning a causal, mechanistic role to large scale brain circuits in the production of those critical behavioral abnormalities. A successful study will help to attain the precise definition of neuromodulation targets for this clinical population in utter need of help.

Focused Ultrasound Neuromodulation in Patients With Treatment-Resistant Depression

The goal of this clinical trial is to evaluate the safety and initial effectiveness of Magnetic Resonance-guided focused ultrasound neuromodulation using the Next Generation Dome Helmet (NGDH) device in patients with treatment-resistant depression. This is a prospective, single-arm, non-randomized study. Participants will: * Undergo two focused ultrasound treatment sessions targeting nodes of the cortical-striatal-thalamic circuit (CSTC) , spaced four weeks apart. * Return for follow-up visits at 24 hours, 2 weeks, and 4 weeks after each treatment session, during which clinical scales and imaging assessments will be conducted to monitor safety and clinical effects.

Psilocybin-Assisted Psychotherapy for Treatment-Resistant Depression: Comparing One Versus Two Doses of Psilocybin

The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.
