Filter by:This is a multi-center, double blind, randomized, placebo-controlled, parallel group, flexible dose titration study conducted in centers in the USA and India. Following a washout period, subject will be treated with citalopram 20 mg once daily for 4 weeks, then with 40 mg once daily for 4 weeks. Subjects who tolerate 40 mg citalopram, but whose MADRS score is < 50% from baseline, but no lower than 17, will be considered partial or non-responders and will be randomized to receive either placebo or TC-5214 as add-on therapy. TC-5214 or placebo will be started at 2 mg daily (BID dosing), and be titrated based on tolerability and therapeutic response up to 8 mg daily. Approximately 560 subjects will enter the Open Label Phase and approximately 220 will enter the double blind phase of the study.
This multi-centred study will be conducted at three centres. The design will be a randomized, placebo-controlled, parallel-group one. This investigation will evaluate the efficacy of add-on Quetiapine XR (extended release) treatment for patients who meet diagnostic criteria for depressive disorders and one or more comorbid anxiety disorder.
The purpose of this study is to determine whether a reduced dose of aripiprazole is effective in treating patients with major depressive disorder
This randomized, double-blind, placebo-controlled, multicenter, 8-week, clinical trial is designed to assess the efficacy and safety of vilazodone and to evaluate genetic biomarkers of treatment response associated with vilazodone use in adult patients diagnosed with MDD by the DSM-IV-TR criteria.
The purpose of this study is to determine the efficacy and safety of once daily vortioxetine (Lu AA21004) in adults with major depressive disorder.
The purpose of this study is to determine the efficacy and safety of vortioxetine, once daily (QD), in adults with major depressive disorder.
This is a short-term study to evaluate the efficacy, safety, and tolerability of escitalopram in adult patients (18 to 65 years of age) with moderate to severe depression. Patients completing the study may be eligible to enter a long-term open-label extension study with escitalopram.
The primary objectives of this placebo-controlled trial are to evaluate effectiveness and safety of DOV 21,947 at two oral dose levels.
This open label 52-week clinical trial is designed to assess the safety and tolerability of vilazodone and to analyze genetic markers of response to vilazodone in adult patients diagnosed with MDD. This study will enroll approximately 600 patients.
Hypothesis I: Patients in the SSRI + ramelteon treatment group will achieve remission (defined as an IDS-C30 score of 11 or less) more quickly than those in the SSRI + placebo group.
