HYpopnea and Apnea Detection and Treatment Performance of a New cardiOreSpiratory Holter Monitor (HYPNOS)

October 2, 2017 updated by: LivaNova

The HYPNOS study is an acute feasibility study to validate a new device for automatic detection and treatment of sleep apnea syndrome. The system is known as the PASITHEA system and it will perform the following tasks:

  • Detect apneas and hypopneas in real time, based on physiological signals acquired with a cardiorespiratory holter (nasal air flow, heart rate and blood oxygen saturation (SaO2))
  • Upon detection of apnea or hypopnea events, trigger kinesthetic stimulation of mechanoreceptors of the skin close to the mastoid bone

The primary objective is to verify that the PASITHEA system is able to detect apneas and hypopneas reliably.

The main secondary objective of the study is to assess the effect of kinesthetic stimulation on reducing the number of sleep respiratory disorders.

Another objective of the study is to verify the safety of the PASITHEA system.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

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

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Description

Inclusion Criteria:

  • above 18 years.
  • Patient with diagnosed severe obstructive sleep apnea syndrome (AHI > 30/h and > 80% of obstructive events diagnosed on polysomnography or polygraphy performed less than 6 months ago )
  • Patient free from CPAP treatment or any other SAS treatment for at least 3 months
  • Patient with stable psychotropic medication since the diagnostic polysomnography or polygraphy exam

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
Performance of real-time detector of apnea and hypopnea: sensitivity and positive predictive value of the detector will be calculated when comparing automatically detected respiratory events to gold-standard PSG scoring of apnea/hypopnea events.
Time Frame: 1 night
During the night of the recording, the PASITHEA system and the PSG will be positioned in parallel. PSG-scored events will be matched with the output of the real-time detector: a true positive event is defined as an event detected less than 10 seconds before or within the duration of a PSG-annotated events. Apneas detected as hypopneas (and reciprocally) will be regarded as true positives. Sensitivity and positive predictive value will be calculated as per conventional definintion and the 9% confidence interval will be calculated using the Wilson score.
1 night

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety: number of adverse events with treatment ON or OFF as defined by ISO 14155, rev 2011
Time Frame: 1 night
All adverse events will be recorded and assessed according to ISO 14155, rev 2011

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
