About this study
Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study To Evaluate The Efficacy And Safety Of DVS-233 SR For Prevention Of Depressive Relapse In Adult Outpatients With Major Depressive Disorder
Primary Objective: To compare the efficacy and safety of DVS-233 SR versus placebo treatment in reducing the relapse rate of depressive symptoms in subjects with major depressive disorder (MDD), and to compare the percentages of relapse in terms of time to relapse between DVS-233 SR and placebo treatment groups by using survival analysis.
Secondary Objective: To assess the response of subjects on DVS-233 SR versus placebo for the clinical global evaluation, functionality, general well-being, pain, and absence of symptoms (Hamilton Psychiatric Rating Scale for Depression, 17-item [HAM-D17] < 7).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing DVS-233 SR in people with Major Depressive Disorder, run by Wyeth is now a wholly owned subsidiary of Pfizer.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Aug 2009. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00075257, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2009; AzTrials last refreshed its copy on 6 Nov 2026.
