Filter by:The primary purpose of this study is to compare the antidepressant efficacy and safety of two doses of desvenlafaxine succinate sustained release (10 and 50 mg/day) in adults with Major Depressive Disorder. The study will also assess changes in sexual function and general and functional quality of life outcomes.
Primary objective: - To evaluate the long-term safety and tolerability of SR58611A (amibegron) patients with major depressive disorder (MDD). Secondary objective: - To determine plasma concentrations of SR58878 (the active metabolite of SR58611A), for pharmacokinetic population analyses, to evaluate the quality of life (QoL) in patients with MDD, and to evaluate the efficacy of amibegron in patients with MDD.
This is an outpatient study to evaluate the safety, and efficacy of RGH-188 as an add-on therapy to standard antidepressants in patients who did not respond to previous antidepressant therapy.
The purpose of this study is to understand the efficacy of light therapy for bipolar depression.
The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. Creatine may have effects of interest in the brain. The reason for the MRI component of this study is to learn about new ways to see inside the brain. The investigators will use magnetic fields and radio waves to look at the brain and chemicals in the brain. The investigators hope that this technique will have medial use in the future. The primary hypothesis of the study is that oral creatine supplementation will have a beneficial effect as adjunctive therapy in female adolescents with MDD who are non-responders to an adequate trial of the SSRIs Fluoxetine or Escitalopram.
The purpose of this study is to assess whether duloxetine is superior to placebo in the treatment of children and adolescents with major depressive disorder (MDD)

The purpose of this research study is to learn more about cognitive deficits in people with certain mood disorders. The mood disorders are Major Depressive Disorder (MDD) and Bipolar disorder, depressed type. Cognitive deficits are problems with things like thinking and memory. People with cognitive deficits may have problems concentrating and paying attention. When talking, they may have trouble recalling a word they want to say. They may think slowly and have problems remembering things. These deficits can affect an individual's ability to work and function socially. Cognitive deficits that occur with depression may increase the risk of a relapse of major depressive disorder. We want to study the course of cognitive impairment in subjects as they are receiving treatment for their depression. We want to find out if their cognitive deficits get better, worse, or stay the same. We also want to learn more about a stress hormone called cortisol that is produced in the body. We want to study the relationship between cortisol and cognitive impairment. Recent research has shown that cognitive impairment may be more severe in people who have high levels of cortisol in their blood. We will also measure the levels of a protein in your blood called brain-derived neurotrophic factor (BDNF). BDNF helps the growth of new brain cells. It appears that the growth of new brain cells lessens when people are depressed. Treatment with antidepressant medications may cause BDNF levels to increase and return to normal. We are interested in studying the relationship between BDNF levels and cognitive impairment throughout treatment.
The primary objective is to evaluate, separately in diabetic polyneuropathic pain (DPNP) patients with and without co-morbid major depressive disorder (MDD), whether duloxetine given as 60 mg to 120 mg once daily (QD) leads to a clinically relevant improvement as measured by the change in Brief Pain Inventory (BPI) 24 hours average interference score from baseline to after 12 weeks. A clinically relevant improvement will be demonstrated if the confidence interval for the mean change from baseline does not lie above the clinically relevant change of -1.35. If statistically significant results are obtained for the DPNP patients with MDD, then the same evaluation will be performed for the DPNP patients without MDD in another confirmatory analysis. As secondary objectives the study will compare the two groups (MDD+/MDD-) regarding efficacy of duloxetine on BPI severity scales, the distribution of different percentages of pain reduction among the patient population, and the patients and physicians impressions of severity and improvement of pain. The study will also compare treatment outcomes regarding patient-relevant functionality and quality of life (QoL) between the two groups (MDD+/MDD-) by evaluating each single BPI interference item, the Short Form 12 (SF-12) Health Questionnaire and the West Haven Multidimensional Pain Inventory (MPI). As a third group of secondary objectives the efficacy of duloxetine of the psychological symptoms (e.g. depression) of DPNP patients with or without depression will be assessed using the Hamilton depression scale, the Beck Depression Inventory-II and the hospital Anxiety and Depression Scale. Further the effect of duloxetine treatment on fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) will be evaluated. To monitor safety and tolerability, treatment discontinuation rates, treatment emergent adverse events, change in vital signs, laboratory results and suicidal thoughts will be assessed.
The purpose of this study is to compare women randomized to Interpersonal Psychotherapy (IPT) and those randomized to usual care in a community mental health center. The main outcome is depression, and it will be assessed in several ways. Other outcome measures will provide vital information about social, psychological, and health functioning. Key patient-level variables that predict outcomes will be identified. The acceptability of IPT will also be examined.
