About this study

Official title: Randomized Controlled Trial of Trazodone Dose Tolerance and APAP Adherence

Trazodone may help obstructive sleep apnea patients to stick to their therapy, but optimal dosing is unknown. This study looks at what dose of trazodone has the best balance of potential benefits to side-effects in people with obstructive sleep apnea who are either starting on positive airway pressure therapy or not adherent to it. Participants will be randomly assigned to one of three groups: trazodone 50 mg, trazodone 100 mg, or placebo for 14 days. The investigators will monitor side-effects and adherence to positive airway pressure therapy.

Read the detailed description

Clinical Significance: Trazodone is an often-used medication in clinical sleep medicine. However, there is a dearth of information on side-effects with doses typically used for sleep. In addition, a significant proportion of the VA population have obstructive sleep apnea for which the primary treatment is positive airway therapy. However, many patients have difficulty adhering to this treatment long-term. Increased adherence to this modality has been shown to improve risk for cardiovascular and neurologic co-morbidity associated with obstructive sleep apnea. This project explores both the tolerability and safety of common doses of trazodone used in clinical sleep practice as well explores potential effects on positive airway pressure therapy adherence.

Objectives: This project seeks to determine the tolerability and multi-domain effect on sleep and mood of a 14 day course of trazodone at either 50 mg or 100 mg or placebo.

Research Plan: This is a three-group, randomized, double-blind, placebo-controlled trial with prospective data collection of VA outpatient sleep clinic patients with obstructive sleep apnea with who are non-adherent or newly started on auto-titrating positive airway pressure therapy. Evaluation focuses on medication tolerability as measured by number of days before study drug discontinuation by the participant, the Treatment Satisfaction Questionnaire for Medication, the side-effect profile at the two doses (50mg and 100mg) compared to placebo as well as longitudinal collection of adherence data and standardized questionnaires on sleepiness, insomnia, depression, anxiety, and self-efficacy. The investigators also plan to longitudinally monitor coefficient of variation of breath-to-breath tidal volume, a measure of respiratory mechanics which may be affected by trazodone use. Study participants will have 2 visits at baseline and 2 weeks after randomization.

Methodology: This study will be conduced in the Louis Stokes Cleveland Medical Center - Wade Park Sleep Clinic, a tertiary institutional referral facility. Participants must be adults with obstructive sleep apnea prescribed auto-titrating positive airway therapy who are either newly initiated or do not fulfill standard criteria for adherence and do not have allergy to trazodone; current use of trazodone, monoamine oxidase inhibitors, or sedative hypnotics; alcohol or drug abuse; severe psychiatric disease; epilepsy; significant cardiac disease; liver disease; pregnancy; hypotension; or predisposition to priapism. Study staff will interview the potential participant and do a review of the medical record for exclusion criteria before consent is obtained. The investigators expect to recruit 45 participants into the study with a 20% attrition rate before completion. Hypothesis about the tolerability of trazodone and effect on positive airway therapy adherence was prespecified.

What is being measured

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

  1. Discontinuation rate by participant

    Did the participant discontinue trazodone at a higher rate than placebo?

    Measured: 14-16 days post-randomization

Secondary outcomes (9)
  1. 3 month APAP adherence

    APAP use in last 30 days (of the 3 month period) as measured by (1) average hours/day and (2) percent days with 4 or more hours use

    Measured: 3 months post-randomization assessing 30 days before this 3 month period

  2. Respiratory patterning

    Variation of breath to breath tidal volume obtained from plethysmography (a stretchy band around the chest x 20 minutes while wearing APAP)

    Measured: 14-16 days post-randomization

  3. Medication Satisfaction

    Treatment Satisfaction Questionnaire for Medications version II overall and subscale scores

    Measured: 14-16 days post-randomization

  4. side-effect profile

    participant-reported side effects of study drug

    Measured: 14-16 days post-randomization

  5. sleepiness

    Epworth Sleepiness Scale

    Measured: 14-16 days post-randomization

  6. insomnia

    Insomnia Severity Index

    Measured: 14-16 days post-randomization

  7. general self-efficacy

    General Self-Efficacy Scale

    Measured: 14-16 days post-randomization

  8. depression

    Clinically Useful Depression Outcome Scale (CUDOS)

    Measured: 14-16 days post-randomization

  9. anxiety

    Clinically Useful Anxiety Outcome Scale (CUXOS)

    Measured: 14-16 days post-randomization

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Trazodone in people with Sleep Apnea, Obstructive, run by Louis Stokes VA Medical Center 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 4 inclusion and 14 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: paused, as of the sponsor's last update on 11 May 2020. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Discontinuation rate by participant (time frame: 14-16 days post-randomization). 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 11 May 2020.
