Filter by:PARADIGM (Progressing TAAR-1, Dopamine, and Norepinephrine in Depression Using Solriamfetol) is a Phase 3, randomized, double-blind, placebo-controlled, multicenter trial to assess the safety and efficacy of solriamfetol for the treatment of major depressive disorder (MDD) in adults.
Although treatments for depression are effective for many people, not everyone responds to treatment. This lack of treatment response could be due, in part, to the presence of multiple underlying causes of people's depression. This study aims to identify subtypes of depression, based on two factors: how successful people perceive themselves to be at regulating their affect in everyday life; and how much activity in the parasympathetic nervous system increases during moments when people try to regulate. The study involves ambulatory assessment of affect, regulation strategies, and physiological activity in everyday life, in a sample of young adults with remitted major depressive disorder and healthy volunteers. We will study regulation responses in the lab to further determine how subtypes differ in neural, physiological, and behavioral responses. Finally, participants will be randomly assigned to a remote, self-administered biofeedback intervention (vs. control intervention) designed to increase parasympathetic activity and physiological regulation success. While engaging in biofeedback at home for 10 days, participants will simultaneously repeat the ambulatory assessments. This design will allow us to determine the proximal impact of biofeedback on indices of regulation success in everyday life, and whether biofeedback has differential impact on regulation success for different subtypes.
Major depressive disorder (MDD) is a common severe psychiatric disease with enormous socioeconomic costs for the patient and society alike. Current pharmacological treatments are ineffective in a substantial fraction of patients and are accompanied by unwanted side effects. Using a novel non-invasive brain stimulation method to specifically target and modulate dysfunctional brain oscillations with high spatial and temporal precision this study will investigate the efficacy of EEG-triggered transcranial magnetic stimulation to alleviate de-pressive symptomatology in patients with MDD in a double-blind randomized controlled pilot clinical trial.
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.
The study is a Phase 2, double-blind, randomized, placebo-controlled study in Major Depressive Disorder (MDD) participants with an inadequate response to standard antidepressants The objective of the study is to assess CLE-100 (oral esketamine) for the treatment of MDD in participants currently treated with an oral antidepressant medication and who have an inadequate response to at least 2 antidepressants.
The goal of this study is to evaluate the effectiveness of an behavioral activation intervention to increase meaningful activity and community participation for people with serious mental illness. The overall objective of this study is to increase engagement in meaningful activities and community participation. The objectives of the project are as follows: 1. To determine if the intervention leads to increases the frequency and variety of activities. 2. To determine if the intervention leads to increases in community mobility. 3. To determine which demographic and environmental factors and mechanisms of action impact the effectiveness of the intervention. 4. To determine if the the intervention leads to an improvement in overall well-being (e.g., improved quality of life). Participants will be asked to attend a 2-hour weekly online session for 10 weeks and then a 1-hour online monthly session for a 3 month maintenance period. For data collection, participants will also be asked to: 1. Complete three, approximately 1-hour interviews at baseline, after the 10 week intervention, and again at the end of the maintenance period; 2. Carry a mobile phone with a global positioning system app to track their movements outside their home for 2 weeks at a time, at three separate times (e.g., baseline, after the intervention, and at the end of the maintenance period); and 3. Complete a 15 minute weekly interviews for 26 weeks about their daily activities and participation. The study will enroll 52 participants split into 4 cohorts of 13. The study will use a multiple baseline design and, as such, all participants will receive the intervention and there is no control group.
The goal of this single-arm, observational pilot study is to learn about the safety, feasibility, preliminary efficacy of TMS for the treatment of depression in people with MS. Participants will receive outpatient TMS treatment over the course of 5-6 weeks. Participants will complete validated questionnaires and exams before, during, and after treatment.
Depressive rumination, a negative thinking style characterized by repetitive and passive thoughts about the causes, meanings, and consequences of one's feelings and distress, is often described as being a habitual response tendency that forms a vulnerability to depression. Behavioural Activation (BA) is an effective treatment for depression but little is known of mechanisms of changes during a successful treatment completion and for whom the treatment benefits the most. The main purpose of the study is to investigate whether habit-like mood-reactive rumination will change during Behavioral Activation treatment for current depression and mediates symptom changes in the treatment. Important moderators of change will also be investigated (i.e. history of early life stress and cognitive flexibility). We aim to provide individual BA treatment for up to 130 currently depressed participants in 12 treatment sessions over 11 weeks. Measures are obtained at pre-treatment, during treatment, at post-treatment and at 6 month follow up.
This two-armed randomized controlled trial aims to investigate the effectiveness of an emotion regulation intervention in individuals with and without depressive disorders. The study encompasses participants diagnosed with mild to moderate major depression or persistent depressive disorder and healthy controls without a current depressive disorder. Participants will be randomly assigned to either the intervention group, receiving a valence-specific emotion regulation intervention in daily life, or a monitoring-only control group. The valence-specific intervention supports the implementation of different emotion regulation strategies based on whether a person is experiencing mainly positive or negative emotions. In contrast, participants in the control group will solely monitor their positive and negative emotions and the strategies used to regulate them. Outcome measures include emotion regulation ability, self-efficacy, and strategy use, depressive symptoms, positive and negative affect, and emotion beliefs (controllability, usefulness). A second aim of the study is to compare beliefs about positive emotions and strategies to regulate them between individuals with and without current depressive disorders. Furthermore, the investigators aim to examine why individuals might choose unfavorable emotion regulation strategies even when feeling good. Therefore, another research question is, how emotion beliefs might explain emotion regulation strategy choice.
The aim of this Phase 2a study in patients with MDD is to assess safety and tolerability and preliminary antidepressant efficacy.
