About this study

Generalized anxiety disorder (GAD) is a very common disorder in the geriatric population with prevalence rates reaching 7% and even higher rates of 8% among elderly veterans. However, despite such high prevalence treating clinicians are presently forced to address treatment issues in this population without the guidance of scientific data. This proposal aims to begin to address this void.

In light of emerging information regarding efficacy of the newer anti anxiety agents, specifically the selective serotonin reuptake inhibitors (SSRIs), in the treatment of young adult GAD patients it is time to prospectively evaluate the safety and efficacy of these medications in the treatment of elderly GAD patients. Therefore, this study will examine the effects and safety of the SSRI sertraline at different doses (50mg and 100mg per day) for older patients with GAD.

Read the detailed description

Generalized anxiety disorder (GAD) is a serious and distinct illness that occurs in significant numbers, affecting at least 7 million people in the United States alone. The prevalence of GAD is higher in the primary care setting with rates twice as high as the rates reported in community samples. GAD is a life-long disorder with low remission rates, resulting in high disability and morbidity. Of significance are emerging epidemiological data suggesting that GAD is highly prevalent in the geriatric population with prevalence rates ranging from 1.9% to 7.1% and accounting for the majority of anxiety disorder cases in this age group. More alarming is the fact that the presence of anxiety symptoms leads to considerable functional impairment, increased morbidity, and mortality among the affected elderly population, thus leading to increases in the costs of their care. However, despite advances made in GAD treatment in the adult population, no prospective data are presently available on the treatment of GAD in the elderly population, forcing clinicians to provide treatment without the guidance of scientific data. These findings are of particular relevance to the Veterans Affairs Health Care System where the average age of patients treated in primary care clinics is currently 60-64 years. The present application focuses on this target subpopulation of elderly veterans.

This proposal aims to provide evidence-based guidelines for pharmacological management of elderly veterans suffering from generalized anxiety disorder. This will be accomplished by conducting a clinical trial in elderly veterans suffering from GAD by evaluating the efficacy and safety of sertraline - a proven anxiolytic compound widely used in the young adult population.

We believe that this proposed study will be one of the first studies in this area. Thus, it may also serve as a first step in a future line of research aimed at developing comprehensive pharmacological and psychosocial interventions in the treatment of anxiety in the elderly.

(b) HYPOTHESIS/RESEARCH QUESTIONS Study Hypothesis In a double-blind, placebo-controlled trial in elderly veterans diagnosed with GAD, sertraline will be more effective and equally safe as placebo in reducing symptoms of generalized anxiety disorder.

Research Question Will the presence of differences in pharmacokinetics (PK) (i.e., mean population values of steady state plasma concentrations) and plasma levels of sertraline explain differences in efficacy and side effect profile between and within the two fixed sertraline doses studied, if detected? (c) SPECIFIC OBJECTIVE The objective of the proposed study is to conduct a multi-site, double-blind, placebo-controlled trial evaluating the efficacy and safety of sertraline at fixed doses vs. placebo in the treatment of GAD among elderly primary care outpatient veterans.

What is being measured

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

  1. Comparisons of End of Study HAM-A Score Means for Sertraline 50 mg vs Placebo, Sertraline 100 mg vs Placebo, and Sertraline 50 mg vs. Sertraline 100 mg

    Least squares (LS) means estimate and p-value from mixed effects model with baseline and site as covariates and Tukey-Kramer adjustment for multiple comparisons Hamilton Rating Scale for Anxiety (HAM-A) is a widely used rating scale for anxiety describes the presence/absence of the severity of anxiety symptoms. It's clinician-rated scale of 14 items rated from 0-4. Generally, total score of <17 is mild anxiety; 18-24 is mild to moderate, and 25 and up is moderate to severe.

    Measured: 11 weeks from baseline

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing sertraline 50 mg daily and sertraline 100 mg daily in people with Generalized Anxiety Disorder, run by VA Office of Research and Development at 3 sites 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 6 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 29 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 29 Dec 2016). 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?

Comparisons of End of Study HAM-A Score Means for Sertraline 50 mg vs Placebo, Sertraline 100 mg vs Placebo, and Sertraline 50 mg vs. Sertraline 100 mg (time frame: 11 weeks from baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Dec 2016.
