About this study

Official title: The Effect of Patient and Investigator Expectation on the Efficacy of Escitalopram in the Treatment of Patients With Major Depressive Disorder.

To evaluate the effect of visit number, patient expectation, and rater expectation of the efficacy of escitalopram treatment in fixed doses of 10 and 20mg, based on baseline severity in patients with MDD.

Read the detailed description

This study is designed to determined if trial design, in the form of the frequency of patient contact (assessment visit numbers) has an effect on the efficacy outcome after 8-week treatment with escitalopram.

The placebo response is a major issue in clinical trials for psychiatric disorders-and especially in the management of depression. Possible contributing factors to this problem include diagnostic misclassification, issues concerning inclusion/exclusion criteria, outcome measures' lack of sensitivity to change, measurement errors, poor quality of data entry and verification, waxing and waning of the natural course of depression, regression toward the mean phenomenon, patient and clinician expectations about the trial, study design issues, non-specific therapeutic effects, and high attrition.

Over the past few decades, researchers have attempted to reduce the placebo effect in a variety of ways. Unfortunately, approaches with very little or no benefit have included restricting enrollment to selected populations, rater training, requirement of same rater, and placebo lead-in phases. Some benefits, although often marginal, have been derived from standardizing diagnostic procedures, managing clinicians' overestimation of change, simplification of study visits and assessments, minimizing nonspecific, therapeutic effects, extending trial duration, reducing number of sites, increasing the sensitivity of outcome measures, and reducing the number of treatment arms.

Thus far, there has been no attempt to develop new study designs aimed at reducing the placebo effect.

We are proposing a novel study design, suitable for doubleblind, trials in mood disorders. This design is aimed at characterizing and identifying both the overall placebo response rate and the sample size required for such

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EscitalopramDrug

    Also called Cipralex, Lexapro

    Patients diagnosed with MDD and will fulfill the inclusion and exclusion criteria will start with escitalopram 10mg, according to the Summary of Product Characteristics. At week 2, patients with a baseline MADRS between 22 and 29 continue on 10mg, and patients with a baseline MADRS > 30 receive a fixed dose 20mg until the end of treatment.

What is being measured

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

  1. Sheehan Disability Scale

    The Sheehan Disability Scale (Sheehan 1983) is a composite of three self-rated items designed to measure the extent to which three major sectors in the patient's life are impaired by panic, anxiety, phobic, or depressive symptoms. This scale has been used widely in psychopharmacology randomized controlled trials, particularly for panic disorder. This anchored visual analog scale uses spatiovisual, numeric, and verbal descriptive anchors simultaneously to assess disability across three domains: work, social life, and family life.

    Measured: Change from baseline to study completion by week 8.

Secondary outcomes (1)
  1. Montgomery Åsberg Depression Rating Scale

    This is a 10-item checklist. Widely used in drug-treatment trials, mainly because of its particular sensitivity to treatment effects. Since there is a comparative lack of emphasis on somatic symptoms, the scale is useful for the assessment of depression in people with physical illness.

    Measured: Change from baseline to study completion in week 8.

Questions about this trial

What is this clinical trial studying?

A study testing Escitalopram in people with Major Depressive Disorder, run by Abarbanel Mental Health Center at 1 site in Israel.

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 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 24 Jun 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 Israel. 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.

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.

What does the primary outcome measure?

Sheehan Disability Scale (time frame: Change from baseline to study completion by week 8.). 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 NCT02480400, 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 24 Jun 2015.
