简要总结
The primary objectives of this placebo-controlled trial are to evaluate effectiveness and safety of DOV 21,947 at two oral dose levels.
详细描述
DOV 21,947 is an investigational drug that is being developed for the treatment of depression. The purpose of this study is to evaluate the safety and effectiveness of a flexible dosing schedule of DOV 21,947 (25 mg twice daily for two weeks, then 50 mg twice daily for four weeks as compared to placebo) in the treatment of major depressive disorder. Information about any side effects that may occur will also be collected.
The efficacy evaluation will be based on the change in the total MADRS and HAMD-17 scores from randomization to week 9 .The secondary objective is to determine if DOV 21,947 improves the quality of life for patients with MDD as compared to placebo

入选标准
- •Males or females between 18 and 65 years of age (inclusive).
- •Either outpatients or inpatients diagnosed with major depressive disorder (MDD) according to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR, see Appendix 3) and MINI International Neuropsychiatric Interview (MINI).
- •Patients with recurrent depressive episode of at least 2 months in duration. Patients must have previously responded (significant clinical improvement judged by the Principal Investigator) to at least one antidepressant treatment.
- •HAMD-17 total score * 22 with a severity score of at least 2 on Item 1 at the Placebo Run-In Visit and the Baseline/Day 1 Visit.
- •HAMD-17 score reduction ≤ 15% between the Placebo Run-In Visit and the Baseline/Day 1 Visit.
- •HAM-A total score < 17 at the Screening Visit.
排除标准
- •Patients with a HAMD-17 total score reduction of more than 15% between the Placebo Run-In Visit and the Baseline/Day 1 Visit (placebo responders).
- •Patients with a medical history of MDD that consistently did not respond significantly to an adequate treatment regimen of a monoamine oxidase (MAO) inhibitor.
- •Patients who are known to be antidepressant treatment-resistant. Patients are defined as treatment-resistant if in the past they have failed adequate antidepressant treatments (dose level approved in the product labeling and was administered for at least 4 weeks) from two or more different pharmacological classes (e.g., TCA, SSRI, SNRI, MAO-I, etc). Failure to respond to an adequate antidepressant treatment is defined as the absence of at least a 50% improvement in symptoms by patient report or documented history, or lack of significant clinical improvement at the Principal Investigator's discretion.
- •Patients with a medical history of MDD who consistently did not respond significantly to electroconvulsive shock therapy (ECT) or had ECT within a year prior to the Screening Visit regardless of outcome.
- •Patients with psychotic depression
