Sleep Apnea in Multiple Sclerosis Positive Airway Pressure Trial (SAMSPAP)

January 10, 2019 updated by: Dr John Kimoff, McGill University

A Randomized, Controlled, Clinical Trial of Continuous Positive Airway Pressure Treatment of Obstructive Sleep Apnea-Hypopnea in Multiple Sclerosis

Fatigue is highly prevalent among multiple sclerosis (MS) patients and has pervasive adverse effects on daily functioning and quality of life. The investigators found in a recent study that obstructive sleep apnea-hypopnea (OSAH) is the most common sleep abnormality in multiple sclerosis (MS) patients. There was also a significant relationship between OSAH and higher fatigue scores in MS patients. Preliminary work from the investigators in this group of subjects shows that treatment of sleep disorders (mostly OSAH) can improve fatigue and other symptoms in some MS patients. However, it is now necessary to systemically test the effect of OSAH treatment in a randomized, controlled study, to be sure that it really does improve fatigue and other symptoms. The best treatment for OSAH in the general population is continuous positive airway pressure (CPAP). This treatment has been well tolerated by most MS patients who have used the device at the investigators' center. This project will therefore be a randomized, controlled, clinical trial of CPAP in MS patients with OSAH. The effects of six months of CPAP treatment on fatigue as well as sleep quality, somnolence, pain, disability, and quality of life will be studied.

Study Overview

Status

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.

Study Type

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers
