Before medications are approved by the U.S. Food and Drug Administration (FDA) or before certain therapy methods are widely accepted as effective, they are tested on people who volunteer to participate in a clinical trial.

Organizations across the country are looking for people like you to take part in their research studies. The list of studies below have been selected from ClinicalTrials.gov based on their inclusion of one or more of the following terms: anxiety disorders, depression, OCD, PTSD, and bipolar disorder.

The Anxiety and Depression Association of America (ADAA) is supportive of research that is conducted through clinical trials. Participating in research can potentially help change the mental health outcomes for you and others who suffer anxiety, depression, and related disorders. You may learn about new interventions/treatments that are being considered.

Effects of Multi-day Interruptions in Sitting on Type 2 Diabetes-relevant Outcomes in Children
University of Southern California Sedentary Behavior Affect Metabolic Disturbance Anxiety Cardiac Autonomic Nervous System Function
The overall objective of this in-lab randomized controlled trial is to test the efficacy of multi-day interruptions in sedentary behavior vs. single bouts of sustained exercise on metabolic, cognitive, affective, and cardiac autonomic nervous system responses in children with overweight and obesity1 expand

The overall objective of this in-lab randomized controlled trial is to test the efficacy of multi-day interruptions in sedentary behavior vs. single bouts of sustained exercise on metabolic, cognitive, affective, and cardiac autonomic nervous system responses in children with overweight and obesity who are at risk for type 2 diabetes. The use of continuous glucose monitoring will provide insight into the daily and cumulative metabolic effects of each condition that have thus far not been studied. In-lab studies demonstrating sustained efficacy of this approach in ameliorating negative effects of sedentary behaviors in children are necessary for the optimization of field-based interventions. Given the lack of success of interventions to prevent obesity-related diseases and increasing rates of type 2 diabetes in children and its related healthcare costs, this study addresses a critical public health need by testing of novel intervention strategies to reduce obesity-related diseases in children with overweight and obesity.

Approximately one in two individuals with bipolar disorder (BD) are non-adherent with medication, often leading to severe and negative consequences. Unfortunately, there is no widely used evidence-based approach to target poor adherence among individuals with BD. Building upon positive efficacy trial results, the proposed project will test the effectiveness of technology-facilitated Customized Adherence Enhancement (CAE) vs. enhanced treatment as usual (eTAU) using a prospective randomized controlled design in public mental health care settings and preferentially enrolling poorly adherent/high-risk individuals with BD. Deliverables include a curriculum-driven adherence enhancement approach that can be implemented in public healthcare settings and which can improve outcomes for the most vulnerable groups of people with BD.

In the United States, adolescents experience alarmingly high rates of major depression, and gold-standard treatments are only effective for approximately half of patients. Rumination may be a promising treatment target, as it is well-characterized at the neural level and contributes to depression onset, maintenance, and recurrence as well as predicts treatment non-response. Accordingly, the proposed research will investigate whether an innovative mindfulness-based real-time functional magnetic resonance imaging (fMRI) neurofeedback intervention successfully elicits change in the brain circuit underlying rumination to improve clinical outcomes among depressed adolescents.

Lack of perceived control, particularly during stress, has been critically implicated in major depressive disorder (MDD) and anhedonic symptoms, especially among female adolescents; yet the neural underpinnings of perceived control disruptions in MDD remain poorly understood.

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. The main goal of the study is to evaluate how safe and effective fosigotifator is in treating MDD. Fosigotifator (ABBV-CLS-7262) is a new treatment being developed for adult patients with depression. This study is double-blinded, which means that neither the patients nor the study doctors know who is given fosigotifator and who is given placebo. Participants will be randomly assigned to one of the two groups to receive fosigatofator or placebo. There is 1 in 2 chance that participants will receive placebo. Approximately 106 adult participants with MDD will be enrolled in approximately 15 sites across the world. Participants will receive oral fosigotifator or matching placebo. Duration of the study is approximately 144 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly 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.

Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. This study will assess how safe and effective ABBV-932 is in treating participants with bipolar I or II disorder. ABBV-932 is an investigational drug being developed for the treatment of depressive episodes in adult participants with bipolar I or II disorder. Study doctors put participants in 1 of 4 groups, called treatment arms. There is a 1 in 4 chance that a participant will be assigned to placebo. Around 160 adult participants with bipolar I or II disorder will be enrolled in approximately 40 sites worldwide. Participants will receive oral capsules of ABBV-932 or matching placebo once daily for 6 weeks. The treatment period will be followed by a safety follow-up (SFU) period for 4 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly visits during the study at a hospital or clinic.

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...
