The goal of this clinical trial is to learn if DT-101 can treat depression in adults. The effect of DT-101 will be compared to placebo. Subjects will attend the clinic every couple of weeks complete general health checks and complete questionnaires.

The purpose of this study is to evaluate the efficacy and safety of KarXT for treatment of Schizophrenia in adolescents.

The goal of this clinical trial is to learn if ACP-211 can help treat adults with major depressive disorder (MDD) who have not improved with antidepressant therapy (ADT), including those with treatment resistant depression (TRD). The main questions the study aims to answer are: * Does ACP-211 work better than a placebo (a look-alike capsule with no medicine) to reduce symptoms of depression? * What adverse events do participants have when taking ACP-211?

The primary objectives of this clinical investigation are to (1) determine the acceptability and feasibility of joining psilocybin-assisted therapy with cognitive-behavioral therapy (PA-CBT) for patients with depression, (2) optimize CBT to most effectively integrate the psilocybin experience with psychotherapy and (3) examine the clinical benefit of psilocybin as an adjunct to cognitive-behavioral therapy (CBT) for major depressive disorder. This study is a randomized, two-arm, fixed dose trial that will test the feasibility, acceptability, and participant and therapist adherence to PA-CBT. Both treatment arms will receive two doses of psilocybin (10mg and then 25mg, separated by one month). In Phase II, participants will be randomized (1:1) to either a 12-session PA-CBT or a 6-session standard psilocybin-assisted therapy (PAT) condition (3 hours of preparation plus 3 hours of supportive therapy integration following the psilocybin experiences).

Major depressive disorder (MDD; depression) is a mood disorder that causes a continued feeling of sadness and loss of interest. It is a common and serious illness that can cause both emotional and physical symptoms such as feelings of sadness, irritability, not being able to focus on activities, tiredness, changes in eating habits, and aches and pains. This study will assess the changes in disease activity and adverse events of oral Icalcaprant in adult participants with major depressive disorder who are currently experiencing a major depressive episode (MDE). Icalcaprant is an investigational drug being developed for the treatment of depressive episodes in adult participants with major depressive disorder. Participants are placed in 1 of 3 groups, called treatment arms. There is a 1 in 3 chance that a participant will be assigned to placebo treatment. Around 195 adult participant with major depressive disorder will be enrolled in approximately 35 sites in North America. Participants will receive oral capsules of Icalcaprant or matching placebo once daily for 6 weeks, with a 30-day safety follow-up. There may be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Multi-centre, parallel group, blinded, 1:1 randomized controlled trial to determine the effect of nitrous oxide on reducing symptoms of depression in patients with treatment resistant depression.

The RESPOND trial explores the link between early life adversity and later life depressive symptoms. The investigators have designed a new psychological therapy tailored to address the symptoms that can be caused by difficult experiences in early life. These symptoms include low mood, emotional dysregulation, and distressing thoughts and beliefs related to difficult or traumatic experiences. The investigators would like to see if this new therapy helps people feel better. The investigators are also studying the biological changes that can occur as a result of early life adversity, and how this therapy may influence those changes. To do this, The investigators ask questions about participants' physical and mental health and take blood samples.

The goal of this study is to improve depression treatment by establishing reliable prefrontal excitability markers through Targeting with Automated Real-time Guidance for Enhancing TEPs (TARGET).

The purpose of this multi-site randomized controlled trial is to evaluate the efficacy and risks of psilocybin for the treatment of depression in U.S. military Veterans with and without (±) concurrent posttraumatic stress disorder.

In this study, investigators are testing whether a higher dose of a non-invasive brain stimulation technique, called transcranial direct current stimulation (tDCS), can be safely used in people with depression. Participants will come to the Brain Stimulation Lab and receive mild electrical stimulation through electrodes placed on their scalp. The study begins with a safety run-in, where the first few participants will receive stimulation at gradually increasing levels (2, 4, and 6 milliamps) while being closely monitored. If no serious side effects are found, later participants will receive repeated 6 milliamp sessions for 5 days total. Investigators will check skin comfort, mood, and overall tolerability after each session.

This study investigates the effects of intentionally sequencing aerobic exercise immediately prior to cognitive behavioral therapy (CBT) to determine its effects on mechanisms of CBT (i.e., working alliance, behavioral activation). To assess the utility of this treatment augmentation, investigators will conduct a randomized controlled trial involving 100 adults with Major Depressive Disorder who will watch a nature documentary while either resting quietly ( 'CalmCBT') or exercising at a moderate intensity ('ActiveCBT') immediately prior to 8 weekly sessions of CBT.

The purpose of this study is to characterize the effect of KarXT on voiding dynamics and urological safety in participants with DSM-5 schizophrenia.
