Trial ID Title Status Sponsor Phase Start Date Summary
NCT00401245 ↗ The Effect Of Dose Titration And Dose Tapering On The Tolerability Of DVS SR In Women With Vasomotor Symptoms Completed Pfizer Phase 3 2006-12-01 Desvenlafaxine succinate (DVS SR) is a serotonin and norepinephrine reuptake inhibitor (SNRI). It is a nonhormonal option for the treatment of Vasomotor Symptoms (VMS) associated with menopause. Nausea is the most common adverse event that is observed in clinical studies and is the main reason for discontinuation during the first week of therapy. Other adverse events (headache, nausea, and dizziness) associated with DVS SR have been noted to occur when subjects abruptly discontinue the medication. The purpose of this study is to evaluate several titration and tapering regimens of DVS SR to ensure a better tolerability profile at the start and completion of treatment. In addition, this study will provide a long posttreatment follow-up to assess any symptoms after treatment is discontinued.
NCT00824291 ↗ Study Evaluating Desvenlafaxine Succinate Sustained Release In Outpatients With Major Depressive Disorder Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 3 2009-02-01 This is a multicenter study to assess the health and well-being in subjects who are outpatients with major depressive disorder that take desvenlafaxine succinate sustained release (DVS SR) or placebo for 12 weeks.
NCT00887224 ↗ Relapse Prevention Study Of Desvenlafaxine Succinate Sustained Release In Outpatients With Major Depressive Disorder Completed Pfizer Phase 3 2009-06-01 The primary purpose of this study is to compare the long-term efficacy and safety of desvenlafaxine succinate sustained release versus placebo in adults with Major Depressive Disorder, using a randomized withdrawal design. Randomized withdrawal means that after receiving desvenlafaxine succinate sustained release for a predetermined period of time, subjects will be selected by chance to either continue receiving the study drug or to be withdrawn from the study drug and receive placebo for the remainder of their participation in the trial. Subjects will not know to which group they have been assigned. The study consists of an up to 14-day screening period followed by an 8-week open-label period in which subjects will knowingly receive 50 mg/day of desvenlafaxine succinate sustained release. Subjects who do not respond to treatment, demonstrating no significant change in their depressive symptoms, will be withdrawn from participation at the end of this period. Responding subjects will receive an additional 3 months of open-label desvenlafaxine succinate sustained release at the same dose. Subjects with stable response to treatment at the conclusion of this 3 month period will be randomized to either desvenlafaxine succinate sustained release at 50 mg/day or placebo in a blinded manner for an additional 6 months or until symptoms of depression return. Following discontinuation at any point after enrollment in the study, subjects will receive two weeks of follow-up monitoring, including one week of blinded taper with 25 mg/day of desvenlafaxine succinate sustained release treatment for any subjects who have been taking desvenlafaxine succinate sustained release prior to discontinuation. Subjects assigned to placebo will receive a blinded placebo taper. Following taper, subjects will be evaluated for one additional week to monitor safety.
NCT00888862 ↗ Desvenlafaxine Succinate (DVS) for Major Depressive Disorder (MDD) in Midlife Men and Women Unknown status McMaster University Phase 3 2009-06-01 The main objective of this study is to characterize a range of brain activation symptoms associated with depression and response to treatment in midlife men and women with MDD, using MRI and functional MRI. Moreover, in the female sub-group, the investigators will examine whether these brain activation symptoms are related to menopausal symptoms (i.e., hot flashes and night sweats). Also, assessing brain activation before and after the treatment might help to uncover some mechanisms associated with the pathophysiology of depression and menopause.
NCT00888862 ↗ Desvenlafaxine Succinate (DVS) for Major Depressive Disorder (MDD) in Midlife Men and Women Unknown status St. Joseph's Healthcare Hamilton Phase 3 2009-06-01 The main objective of this study is to characterize a range of brain activation symptoms associated with depression and response to treatment in midlife men and women with MDD, using MRI and functional MRI. Moreover, in the female sub-group, the investigators will examine whether these brain activation symptoms are related to menopausal symptoms (i.e., hot flashes and night sweats). Also, assessing brain activation before and after the treatment might help to uncover some mechanisms associated with the pathophysiology of depression and menopause.
