A Study to Determine the Flow Changes And/or AHI Reduction When Stimulating Two Targets (neural And/or Muscular) for the Treatment of Obstructive Sleep Apnea in Adult Subjects

October 8, 2024 updated by: Invicta Medical Inc.

Single Center Proof-of-Concept Study to Determine the Flow Changes And/or AHI Reduction When Stimulating Two Targets (neural And/or Muscular) for the Treatment of Obstructive Sleep Apnea in Adult Subjects

This Proof-of-Concept study will collect acute and sub-acute flow and/or AHI data following the placement of lead arrays under direct vision. The acute placement and data collection will be collected following the completion of the pre-scheduled neck dissection surgery. The sub-acute data will be collected in a sleep lab during a polysomnography (PSG). Both data collections will be done when stimulating (using an external pulse generator) the hypoglossal nerve or Genioglossus muscle (GG) and a second neural target (Ansa Cervicalis - AC) or the strap muscles (sternohyoid and sternothyroid) with a set of Off-the-Shelf (OTS) electrode arrays.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
3

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

A patient must meet all of the following inclusion criteria to be eligible for inclusion in this study:

  • Age above 18 years not under guardianship, under curatorship or under judicial protection.
  • Body Mass Index (BMI) < 38 kg/m2.
  • Subject must be eligible for neck dissection surgery.
  • Written informed consent obtained from the patient prior to performing any study specific procedure.
  • Willing and capable to comply with all study requirements, including specific lifestyle considerations, evaluation procedures and questionnaires for the whole duration of the trial.

Exclusion Criteria:

Patients meeting any of the following criteria will be excluded from participation in this study:

  • Major anatomical or functional abnormalities that would impair the ability of the electrode arrays to be positioned.
  • Significant comorbidities that contraindicate surgery or general anesthesia.
  • Significant tongue weakness.
  • Aerodigestive tract tumor or reconstructive surgery performed at the same time as neck dissection.
  • Any other chronic medical illness or condition that contraindicates a surgical procedure or general anesthesia in the judgment of the investigator.

  • Prior surgery or treatments that could compromise the placement and effectiveness of the electrode array systems:

    • Airway cancer surgery or radiation, or
    • Mandible or maxilla surgery in the previous 3 years (not counting dental treatments).
  • Other upper airway surgery to remove obstructions related to OSA in the previous 3 months (e.g., uvulopalatopharyngoplasty (UPPP), tonsillectomy, nasal airway surgery).
  • Prior hypoglossal nerve stimulation device implantation.
  • Currently pregnant or breastfeeding during the study period.
  • Concomitant oral or pharyngeal surgery.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Target stimulation
Stimulation of a combination of targets: Hypoglossal nerve (HGN) and Ansa Cervicalis (AC), Genioglossus (GG) and AC, HGN and strap muscles, or GG and strap muscles, during an acute and sub-acute phase.

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
Impacts on acute airway opening
Time Frame: Day 0 to 3
Demonstration of acute airway opening as visually observed under nasoendoscopy when stimulating the HGN or GG and a second target (neural or direct muscle stimulation).
Day 0 to 3
Impacts on airflow during a acute assessment
Time Frame: Day 0 to 3
Acute increase in airflow when stimulating the HGN or GG and a second target (neural or direct muscle stimulation), measured by changes in amplitude (mA) during target stimulation.
Day 0 to 3

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
Impacts on airway opening during a sub-acute assessment
Time Frame: Day 0 to 3
Demonstration of sub-acute flow increase and/or AHI reduction when stimulating two targets simultaneously during natural sleep as measured with polysomnography (PSG), measured by polysomnography.
Day 0 to 3
