Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • At least 18 years of age
  • Previous diagnosis of primarily obstructive mild-moderate Sleep Disordered Breathing during in-laboratory polysomnography
  • Ability to read and understand English Language
  • Ability to provide informed consent

Who cannot join

  • Unstable medical illness within the last month (30 days)
  • Acute / recent upper airway infection
  • Prior use of non-continuous positive airway pressure medical technology therapies prescribed by a physician for the management of obstructive sleep disordered breathing (e.g., Provent®, Winx™, mandibular advancement oral appliances, etc.)
  • Prior use or exposure to CPAP / Bi-Level / or other non-invasive ventilatory modalities
  • Craniofacial or other anatomical anomalies that may predispose patients to upper airway obstruction, or obvious blockage to nasal air flow
  • Patients using opioids or amphetamines will be excluded from the study.
Show all 14Show fewer
  • Enhanced oxygen requirement (i.e., FiO2>0.21)
  • Patients requiring Bi-Level therapy upon CPAP titration attempt
  • Surgery since the diagnostic PSG
  • Significant recent sedative/hypnotic use likely, in the opinion of the principle investigator, to impair ventilatory control or impact the subsequent titration of either CPAP therapy or Flowrest therapy (including benzodiazepines, antihistamines, imidazopyridines)
  • Significant use of stimulant medications likely, in the opinion of the principle investigator, likely to alter ventilatory or upper airway control and impact the subsequent titration of either CPAP therapy or Flowrest therapy (including amphetamines, high dose caffeine, etc.)
  • Significant neurologic or cardiac pathology likely to seriously impact respiratory effort or ventilatory control (e.g., post CVA with ventilatory impairment)
  • Presence of significant sleep disorders likely to induce hypersomnolence or interfere with the ability to titrate CPAP therapy or Flowrest therapy (including narcolepsy, PLMS/RLS, severe chronic insomnia, non-OSA obesity hypoventilation syndrome, etc.)
  • Unsuitable for inclusion in the opinion of the investigators

About this study

Official title: Effect of High Flow Nasal Cannula (Flowrest®) on Mild-Moderate Sleep Disordered Breathing: A Non-Inferiority Study Versus Nasal Continuous Positive Airway Pressure (CPAP) Therapy

Order randomized crossover non-inferiority study evaluating the acute efficacy of High Flow Therapy (HFT) as compared to nasal Continuous Positive Airway Pressure therapy (CPAP) in the management of apnea / hypopnea index (AHI).

Read the detailed description

Study to evaluate the acute efficacy of a single night of High Flow Therapy (HFT) to treat mild-moderate predominantly obstructive Sleep Disordered Breathing, as compared to nasal Continuous Positive Airway Pressure (CPAP) therapy. Subjects will be order-randomized to receive HFT or CPAP in the laboratory, undergo a washout period, and return for the alternative therapy in the laboratory. The hypothesis is that HFT will be non-inferior to CPAP in controlling Apnea/Hypopnea events in this subject set during this study.

Primary outcome will be Apnea / Hypopnea Index (AHI) change on therapy as compared to baseline diagnostic polysomnography.

What is being measured

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

  1. AHI Change (Therapy v Baseline)

    Evaluate the change in AHI from baseline for HFT v CPAP therapy

    Measured: Acute - single night therapy exposure

Secondary outcomes (4)
  1. Pulse Oxygen Saturation

    Evaluate the mean, absolute minimum, absolute event-related nadir and mean nadir of pulse oxygen saturation during therapeutic polysomnography of HFT v CPAP

    Measured: Acute single night therapy exposure

  2. Sleep Architecture (WASO, %W, N1, N2, N3, REM, SL, RL, AI)

    Evaluate changes in sleep architecture on HFT and CPAP therapy as compared to baseline diagnostic polysomnography. Specifically, evaluate any difference between the therapies on %Wake Time (of SPT), % time in stages N1, N2, N3, REM (of TST), Minutes of Wake After Sleep onset, Sleep latency and REM Latency. Any difference in overall non-respiratory arousal index will be assessed.

    Measured: Acute single night therapy exposure

  3. Respiratory Event Related Arousals

    Compare the incidence of RERA on HFT and CPAP therapy as compared to diagnostic polysomnography.

    Measured: Acute single night therapy exposure

  4. Respiratory Disturbance Index (RDI)

    Evaluate the RDI on HFT v CPAP therapy as compared to the diagnostic polysomnography.

    Measured: Acute single night therapy exposure

Questions about this trial

What is this clinical trial studying?

A study testing High-Flow Therapy and Continuous Positive Airway Pressure in people with Mild-Moderate Obstructive Sleep Disordered Breathing, run by Vapotherm, Inc. 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: withdrawn, as of the sponsor's last update on 3 May 2023. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

AHI Change (Therapy v Baseline) (time frame: Acute - single night therapy exposure). 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 3 May 2023.
