Filter by:The main purpose of this study is to assess the efficacy and safety of daily and intermittent dosing of MK-1942 compared to placebo among participants with Treatment-Resistant Depression (TRD) on a stable course of antidepressant therapy. The dual primary hypotheses of the study are that the daily MK-1942 treatment and/or intermittent MK-1942 treatment are superior to placebo in reducing Montgomery-Asberg Depression Rating Scale (MADRS) score.
The investigators will conduct a randomized controlled trial (RCT), comparing SSM (n=96) versus HEP (n=96) in 192 LLD participants stratified by site and presence of treatment resistant late life depression (TR-LLD). Participants will be blinded to the treatment hypothesis while investigators, raters and treating clinicians will be additionally blinded to the intervention. Both SSM and HEP will be taught over 4 consecutive days in similar sized groups (4-10 participants) followed by weekly reinforcement sessions for subsequent 11 weeks. Trained raters will collect data on depression symptoms (HAM-D 17 scale) and cognition at baseline, 12-week and 26-week follow-up as the primary and secondary outcome measures respectively.
The investigators are doing this research study to find out if using aspirin along with antidepressant treatment can lessen symptoms of depression. This study also aims to find out if some people improve more from taking aspirin than others. The investigators also want to see if it is possible to predict which participants will do better based on a blood test. Aspirin is approved by the U.S. Food and Drug Administration (FDA) as an over-the-counter pain medication. But, aspirin is not approved by the FDA to make antidepressant treatment better. This research study will compare aspirin to placebo.
The primary objective of this study is to determine the effectiveness of serial infusions of intravenous (IV) ketamine in adults with treatment resistant depression (TRD).
This study is intended to evaluate the safety and potential efficacy of Allogeneic Human Mesenchymal Stem Cell Infusion versus placebo in patients with Treatment Resistant Depression.
This study is looking at the efficacy, rapidity, safety, and tolerability of two doses of oral CERC-501 for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.
The purpose of this study is to assess the efficacy and safety of olanzapine and fluoxetine compared to placebo and fluoxetine as treatment for treatment-resistant depression (TRD) in Chinese participants.
This is an ancillary study to a clinical trial that is being conducted at Massachusetts General Hospital. Investigators at MGH are conducting a clinical trial to test the efficacy of ziprasidone together with escitalopram for treatment-resistant depression (NCT00633399). This observational study will involve magnetic resonance scans to examine brain chemistry (neurotransmitter levels), brain activity, and functional connections between brain regions before and after participating in the trial. The neurotransmitters of interest are glutamate, glutamine, and GABA. Comparisons will be made between individuals who receive ziprasidone and individuals who receive an inactive placebo. Differences between participants who respond to standard antidepressants and those who require additional medication will also be examined. All participants will have a baseline magnetic resonance scan before starting medication. The second scan will be after 8 weeks of escitalopram treatment for those who respond or following 8 weeks of escitalopram plus ziaprasidone or placebo (16 weeks after starting) for those who do not respond to escitalopram alone. Participants will complete standard rating scales for depression at each visit.
More than one out of three individuals treated for major depressive disorder (MDD) do not experience a full reduction of symptoms even when treated with adequate antidepressant medication. These individuals may have treatment-resistant depression. This is a condition that contributes to the tremendous costs of MDD, in terms of health care costs, functional impairment (limitation of an individual's functional ability), and diminished quality of life. There is a clear need for personalized medicine, for people at high risk for treatment-resistant depression. If these individuals could be identified early in the course of their depression, they could be recommended for more intensive or specialized interventions. Doing so could improve their likelihood of having a full reduction in their symptoms. Today, there are many treatment options for MDD. Individuals can spend months or years in and out of treatment before receiving one that works for their treatment-resistant depression. The investigators want to study treatment resistant depression by examining specific genes (genotyping) that might influence how your body responds to certain antidepressant medications. This process of examining specific genes is not experimental. To look at your specific genes, the investigators will collect a blood sample. Genes contain the material passed from parent to child that determines the make-up of the body and mind. For example, some genes control the color of your hair or eyes. Genes are contained in your DNA (deoxyribonucleic acid). There are many differences in DNA, from one person to another. These differences may affect a person's chances of having a particular disease.
