Active clinical trials for "Depressive Disorder"

The purpose of this study is to compare the antidepressant efficacy, safety, and tolerability of DVS-SR in subjects receiving daily doses of 50 mg or 100 mg of DVS-SR versus subjects receiving placebo.

The purpose of the study is to evaluate the efficacy and safety of saredutant (or SR48968C) in patients with depression. The primary objective is to evaluate the efficacy of a 100 mg dose of saredutant compared to placebo in patients with depression. The secondary objectives are to evaluate the safety of saredutant, to evaluate the efficacy of saredutant on disability and quality of life in patients with depression, and to evaluate blood levels of saredutant.

The purpose of this study is to determinate if accelerated rTMS treatment over 1.5 days is effective for ameliorating depression in Parkinson's disease.

To evaluate the efficacy of a fixed dose of SR58611A(350 mg q12) compared to placebo in patients with MajorDepressive Disorder (MDD) using escitalopram (10 mgqd) as positive control. In addition, the tolerability and safety of SR58611A in patients with MDD will be evaluated.

This is an assessment of the efficacy of venlafaxine-HCL augmentation with the neuroleptic quetiapine in treatment resistant depression.

The primary objective of this study is to assess the efficacy of olanzapine and fluoxetine combined on all the visits as compared with the baseline visit in patients with bipolar disorder, measured by the total score of the Montgomery-Asberg Depression Rating Scale (MADRS).

A study in patients with depression

The purpose of this study is to test the hypothesis that duloxetine (Cymbalta), in doses of 60 or 120 mg/day, is an effective and tolerable treatment for adult outpatients suffering from dysthymia. Dysthymia is chronic, mild depression characterized by feeling sad or low more days than not for more than 2 years.

Objectives: This prospective investigation will compare premenopausal, perimenopausal and postmenopausal women's response to antidepressant medication. The effects of the menstrual cycle on the symptoms of depression and antidepressant response will also be examined. Hypotheses: Premenopausal women will show a significantly better response to a selective serotonin reuptake inhibitor (SSRI) than peri- or postmenopausal women. Premenopausal women during lower estrogen phases of the menstrual cycle will complain of increased depressive symptoms despite treatment. Perimenopausal and postmenopausal women with irregular periods and generally low estrogen levels will show less symptom variability over time. Method Subjects: Eighty-four women (28 premenopausal, 28 perimenopausal, 28 postmenopausal) meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for major depressive disorder will be enrolled in the study. Procedure: All the subjects will be followed prospectively for 12 weeks and through 2 menstrual cycles while receiving treatment with a standard SSRI antidepressant agent. All eligible women will have a structured clinical interview and will complete questionnaires assessing their depressive symptoms. Blood samples will be collected to evaluate for reproductive hormone levels during the late follicular, midluteal and late luteal phases of the menstrual cycle for two consecutive cycles. Serum SSRI levels will also be collected at these times. As the women in the perimenopausal and postmenopausal groups either have irregular menstrual cycles or no longer cycle, they will have blood samples drawn at baseline and on 6 other occasions. Research Implications: As the majority of psychiatric medication is prescribed to women, understanding the interplay between the menstrual cycle and antidepressant medication will ultimately translate into more diverse and improved patient care. The proposed study is one within a developing research program, which will in part be further guided by this study.

This study aims to treat young people with an adjunctive integrated cognitive behavioral therapy (CBT) intervention and to examine the acceptability of this treatment approach within this population. The study will also include a pilot placebo-controlled trial of sertraline for those young people who fail to or only partially respond to the CBT intervention, so as to determine whether adjunctive anti-depressant treatment improves clinical response in this population.
