Mirtazapine for Chronic Insomnia in Older Adults (MIRAGE)

August 9, 2024 updated by: Centre hospitalier de l'Université de Montréal (CHUM)

Safety and Efficacy of Mirtazapine in the Treatment of Chronic Insomnia in Older Adults : The MIRAGE Study

Insomnia is highly prevalent in the older adult population. The pharmacolgical management of chronic insomnia includes benzodiazepines and Z-drugs (zolpidem, zopiclone). Although these drugs are indicated for insomnia, they are not without side effects. These drugs are associated with cognitive impairment, rebound insomnia, falls and addiction. Mirtazapine has a hypnotic and sedative effect related to the blocking of histamine-1 receptors. No clinical trials has evaluated the efficacy and safety of mirtazapine for insomnia in the older population.

The goal of the study is to assess the efficacy and safety of mirtazapine compared to a placebo in older adults with chronic insomnia.

This prospective double-blind placebo controlled trial will be conducted in adults 65 years and older with chronic insomnia. The treatment group will receive mirtazapine 7.5 mg at bedtime for 28 days and the control group will receive a matching placebo for 28 days. The sample size for the pilot study will be 60 subjects, 30 subjects in the treatment group and 30 subjects in the control group. The efficacy of mirtazapine will be measured using the Insomnia Severity Index and the Pittsburgh Sleep Quality Index. Safety will be monitored during the study

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Insomnia Severity Index
Time Frame: For Mirtazapine and placebo group : Assess the change in the Insomnia Severity Index between the initial examination (Day 1) and the end of the treatment course (Day 36)
Self-reported insomnia symptoms using an insomnia severity scale from 0 to 28, 28 being the worst outcome
For Mirtazapine and placebo group : Assess the change in the Insomnia Severity Index between the initial examination (Day 1) and the end of the treatment course (Day 36)
Pittsburgh Sleep Quality Index
Time Frame: For Mirtazapine and placebo group : Assess the change in the Pittsburgh Sleep Quality Index between the initial examination (Day 1) and the end of the treatment course (Day 36)
Sleep scale from 0 to 21, 21 being the worst outcome
For Mirtazapine and placebo group : Assess the change in the Pittsburgh Sleep Quality Index between the initial examination (Day 1) and the end of the treatment course (Day 36)
