About this study

Official title: A Randomized, Double-Blind, 8-week Comparing Safety and Tolerability of Switching From Generic Selective Serotonin Reuptake Inhibitors (SSRIs) and Selective Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs) to Three Different Dose Initiation Strategies With Vilazodone

This is an 8-week, randomized, double blind, parallel group, 3-arm trial to compare 10 mg/day, 20 mg/day and 40 mg/day as starting doses of vilazodone following a switch from generic SSRIs and SNRIs. Vilazodone HCl under the trade name Viibryd™ is approved by the U.S. FDA for the treatment of major depressive disorder in adults. The purpose of this study is to evaluate the efficacy (how well the drug works), safety (the side effects), and tolerability (how well tolerated) of Vilazodone in preventing relapse or recurrence of depression. As vilazodone is not approved by the United States Food and Drug Administration (FDA) to prevent the recurrence of depression, for the purposes of this study it is considered investigational. The word "investigational" means that the study drug is still being tested in research studies and has not been approved for this use by the FDA.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Total MADRS Scores From Baseline to Week 8

    The efficacy of switching to three different doses of vilazodone (10 mg/d, 20 mg/d, 40 mg/d) from equivalent dose range of generic SSRIs or SSNRIs in patients with MDD measured by the MADRS. The MADRS is a 10-item scale that evaluates the core symptoms and cognitive features of clinical depression. Each MADRS item is rated on a 0 to 6 scale. The MADRS Total score ranges from 0 (min) to 60 (max). Higher MADRS scores indicate higher levels of depressive symptoms.

    Measured: Baseline, Week 8

  2. Change in the Discontinuation Emergent Signs and Symptoms Check List (DESS)

    DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The primary tolerability measure for discontinuation symptoms will be The Discontinuation Emergent Signs and Symptoms Check List (DESS). Discontinuation symptoms that do not respond to education and supportive psychotherapy will be managed by reinstituting the last dose of Vilazodone at which patients did not experience discontinuation symptoms and slowly tapering the dose over 1 week or longer, if necessary.

    Total possible range is 0 to 172. A higher score indicates more symptoms.

    Measured: Baseline, week 9

  3. Change in Safety as Assessed by the Arizona Sexual Experience Scale (ASEX)

    The Arizona Sexual Experience Scale (ASEX) is a 5-item, patient selfrated scale that evaluates a patient's recent sexual experience. Patients are asked to assess their own experience over the last week (for example, "How strong is your sex drive?", "Are your orgasms satisfying?") and respond on a 6-point scale for each item. The ASEX is used to identify individuals with sexual dysfunction. Possible total score ranges from 5 to 30, with the higher score indicating more patient sexual dysfunction.

    Measured: Baseline, Weeks 8

Secondary outcomes (6)
  1. Change in Hamilton Anxiety Rating Scale (HAM-A) Total Scores

    HAM-A=clinician-rated interview measuring presence of anxiety-related symptoms in 14 areas including anxiety, tension, depressed mood, palpitations, breathing difficulties, sleep disturbances, \& restlessness. Total score ranges from 0 to 56; higher score indicates greater anxiety.

    Measured: Baseline, 8 weeks

  2. Change in Sheehan Disability Scale (SDS)

    The Sheehan Disability Scale assesses functional impairment in 3 domains: work/school, social life or leisure activities, and home life or family responsibilities. The participant rates the extent to which each aspect is impaired on a 10-point visual analog scale, from 0 (not at all) to 10 (extremely). The 3 scores are added together to calculate the total score, which ranges from 0 to 30, with higher scores indicating more impairment.

    Measured: Baseline, 8 week

  3. Change in Clinical Global Impression-Improvement (CGI-I) Scale

    The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

    Measured: Baseline, Week 8

  4. Change in Clinical Global Impression-Severity (CGI-S) Scale

    The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants". Higher scores indicate worsening.

    Measured: Baseline, 8 week

  5. MADRS Response

    Number of subjects who had a ≥ 50% decrease in MADRS score from baseline

    Measured: Baseline, Week 8

  6. MADRS Remission

    MADRS remission is defined as MADRS score < 10

    Measured: Week 8

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Vilazodone in people with Major Depressive Disorder (MDD), run by Duke University at 1 site in United States.

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 8 inclusion and 10 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 16 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 9 Feb 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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.

What does the primary outcome measure?

Change in Total MADRS Scores From Baseline to Week 8 (time frame: Baseline, Week 8). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02015546, which also lists 1 linked publication.

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 16 Apr 2015.
